    A course of a game is formulated as a physical process that will consume free energy in the least time. Accordingly, the rate of entropy increase is the payoff function that will subsume all forms of free energy that motivate diverse decisions. Also other concepts of game theory are related to their profound physical counterparts. When the physical portrayal of behavior is mathematically analyzed, the course of a game is found to be inherently unpredictable because each move affects motives in the future. Despite the non-holonomic character of the natural process, the objective of consuming free energy in the least time will direct an extensive-form game toward a Lyapunov-stable point that satisfies the minimax theorem. -- Highlights: → Behavior in the context of game theory is described as a natural process. → The rate of entropy increase, derived from statistical physics of open systems, is identified as the payoff function. → Entropy as the payoff function also clarifies motives of collaboration and subjective nature of decision making. → Evolutionary equation of motion that accounts for the course of a game is inherently unpredictable.

  8. Effect of hunting awareness on wild game meat purchase behavior

    Full Text Available Although wild game meat constitutes a sustainable and healthy alternative to conventional meat and hunting contributes to the control of game populations, international studies on consumer attitudes towards this type of meat are still limited and no previous research has been focused on the Italian population. For the development of successful marketing strategies and/or public policy intervention, the knowledge of consumers’ purchase behavior is a key factor. Among all the determinants that can influence the behavior of consumers of hunted wild game meat (i.e. animal welfare, sustainability, ecological food choice, product safety, nutritional quality, the consumers’ awareness of hunting activity and their perceptions of wild game meat assume a crucial role. Accordingly, in this paper an online survey on a sample of 741 Italian meat consumers has been conducted to investigate the relationship between consumers’ purchase behavior and their awareness of hunted game meat and hunting practices (chi-square test, F-test. Statistically significant differences were found among segments of consumers with different levels of wild game meat consumption frequency. The analysis shows that, as expected, the highest consumption level of wild game meat relates to the highest level of general awareness of wild game meat and hunting practices. Our findings are in line with previous literature, that links positive behaviors of consumers towards wild game meat and hunting to familiarity and experience with hunting and hunters. Nonetheless, the present study provides a deeper understanding of the Italian consumers’ attitudes and perceptions of wild game meat and could suggests policy guidelines for the development of future targeted marketing strategies.

  12. Provisioning of game meat to rural communities as a benefit of sport hunting in Zambia.

    Full Text Available Sport hunting has reportedly multiple benefits to economies and local communities; however, few of these benefits have been quantified. As part of their lease agreements with the Zambia Wildlife Authority, sport hunting operators in Zambia are required to provide annually to local communities free of charge i.e., provision a percentage of the meat obtained through sport hunting. We characterized provisioning of game meat to rural communities by the sport hunting industry in Zambia for three game management areas (GMAs during 2004-2011. Rural communities located within GMAs where sport hunting occurred received on average > 6,000 kgs per GMA of fresh game meat annually from hunting operators. To assess hunting industry compliance, we also compared the amount of meat expected as per the lease agreements versus observed amounts of meat provisioned from three GMAs during 2007-2009. In seven of eight annual comparisons of these GMAs, provisioning of meat exceeded what was required in the lease agreements. Provisioning occurred throughout the hunting season and peaked during the end of the dry season (September-October coincident with when rural Zambians are most likely to encounter food shortages. We extrapolated our results across all GMAs and estimated 129,771 kgs of fresh game meat provisioned annually by the sport hunting industry to rural communities in Zambia at an approximate value for the meat alone of >US$600,000 exclusive of distribution costs. During the hunting moratorium (2013-2014, this supply of meat has halted, likely adversely affecting rural communities previously reliant on this food source. Proposed alternatives to sport hunting should consider protein provisioning in addition to other benefits (e.g., employment, community pledges, anti-poaching funds that rural Zambian communities receive from the sport hunting industry.

    Wild game hunting is a popular activity in many regions of the United States. Recently, the presence of lead fragments in wild game meat, presumably from the bullets or shot used for hunting, has raised concerns about health risks from meat consumption. This study examined the association between blood lead levels (PbB) and wild game consumption. We recruited 742 participants, aged 2-92 years, from six North Dakota cities. Blood lead samples were collected from 736 persons. Information on socio-demographic background, housing, lead exposure source, and types of wild game consumption (i.e., venison, other game such as moose, birds) was also collected. Generalized estimating equations (GEE) were used to determine the association between PbB and wild game consumption. Most participants reported consuming wild game (80.8%) obtained from hunting (98.8%). The geometric mean PbB were 1.27 and 0.84 microg/dl among persons who did and did not consume wild game, respectively. After adjusting for potential confounders, persons who consumed wild game had 0.30 microg/dl (95% confidence interval: 0.16-0.44 microg/dl) higher PbB than persons who did not. For all game types, recent (game consumption was associated with higher PbB. PbB was also higher among those who consumed a larger serving size (> or = 2 oz vs. game' consumption only. Participants who consumed wild game had higher PbB than those who did not consume wild game. Careful review of butchering practices and monitoring of meat-packing processes may decrease lead exposure from wild game consumption.

  15. Sexual dimorphism in relation to big-game hunting and economy in modern human populations.

    Collier, S

    1993-08-01

    Postcranial skeletal data from two recent Eskimo populations are used to test David Frayer's model of sexual dimorphism reduction in Europe between the Upper Paleolithic and Mesolithic. Frayer argued that a change from big-game hunting and adoption of new technology in the Mesolithic reduced selection for large body size in males and led to a reduction in skeletal sexual dimorphism. Though aspects of Frayer's work have been criticized in the literature, the association of big-game hunting and high sexual dimorphism is untested. This study employs univariate and multivariate analysis to test that association by examining sexual dimorphism of cranial and postcranial bones of two recent Alaskan Eskimo populations, one being big-game (whale and other large marine mammal) hunting people, and the second being salmon fishing, riverine people. While big-game hunting influences skeletal robusticity, it cannot be said to lead to greater sexual dimorphism generally. The two populations had different relative sexual dimorphism levels for different parts of the body. Notably, the big-game hunting (whaling) Eskimos had the lower multivariate dimorphism in the humerus, which could be expected to be the structure under greatest exertion by such hunting in males. While the exertions of the whale hunting economic activities led to high skeletal robusticity, as predicted by Frayer's model, this was true of the females as well as the males, resulting in low sexual dimorphism in some features. Females are half the sexual dimorphism equation, and they cannot be seen as constants in any model of economic behavior.

    Full Text Available Knowing the profileof hunting tourism consumers is particularly useful to the administrators ofhunting funds or natural parks, and of travel agencies that develop huntingtourism products for the hunting of large game for trophy, of small game asrecreational activity and also for the experienced hunting tourists who loveadventure and hunting with traditional weapons. The motivation for huntingconsists in the existing fauna in a certain area, but there are also cultural,historical reasons or spending time in the middle of nature. Consumers ofhunting tourism have a wide range of ages: hunting tourists prefer watching theanimals in their natural habitat and are less adventure-oriented, unlike trophyhunting tourists who are self-contended, travel much and wish to know thehistory, the culture and the behaviour of animals in protected areas. Theyprefer special accommodation and transport conditions and rely on largeincomes: they wish to get the rarest trophies to display back home as a symbolof their hunting skills and courage

    Development from extracting oil and gas resources can have unintended effects on multiple ecosystem functions, with cascading effects on wildlife, ecosystem services, and local economies. Big-game hunting opportunities may be closely related to these effects, but empirical analyses of impacts of energy development on hunting are limited. We examined the influence of oil and gas development density on harvest efficiency, or harvest per unit of hunter effort, within all hunt areas in Wyoming, USA, from 2008 to 2014 for 3 big-game species: elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana). Using harvest/hunter day as the response variable, we compared linear mixed-effects models for each species that included total well density (i.e., all wells constructed up to the year of record), active well density (i.e., only those wells currently producing oil or gas in that year), or neither as a predictor variable. We used well densities as indicators of development in the absence of data specifying the locations of other oil and gas infrastructure (e.g., roads, well pads). Models also accounted for the fixed effects of road density, hunter density, proportion of the area that is public land with unrestricted hunter access, proportion of the area that is forested, year of observation, and random effects of variation among hunt areas nested within associated game herd units. Presence of oil and gas wells had a positive influence on harvest efficiency for elk and mule deer. Although there was no overall effect to pronghorn, there was a negative influence of wells on juvenile pronghorn harvest efficiency. Changes in harvest efficiency due to expanding oil and gas development could alter the time spent hunting by hunters and their chances of harvesting an animal. This could have subsequent impacts on hunter satisfaction, game populations, and economic revenue generated from recreational hunters.

    The amount of caesium 134 and 137 in Hessian game hunted for food (556 animals) after the reactor accident at Chernobyl was investigated. Comparisons have been made before and after the accident. Although there was only a very low level of contamination, the contamination rate of different species varied; on average, the Red Deer showed the highest activity (130 Bq/kg). The level of caesium contamination was mostly influenced by the permanent habitat of the animals. The main influence was due to regional, geographical and meteorological conditions. The influence of age or sex could not be determined. The contamination rate was shown to decrease with time [de

    The Greater Yellowstone Ecosystem contains the rare combination of an intact guild of native large carnivores, their prey, and differing land management policies (National Park versus National Forest; no hunting versus hunting). Concurrent field studies on large carnivores allowed us to investigate activities of humans and carnivores on Yellowstone National Park's (YNP) northern boundary. Prior to and during the backcountry big-game hunting season, we monitored movements of grizzly bears (Ursus arctos), wolves (Canis lupus), and cougars (Puma concolor) on the northern boundary of YNP. Daily aerial telemetry locations (September 1999), augmented with weekly telemetry locations (August and October 1999), were obtained for 3 grizzly bears, 7 wolves in 2 groups of 1 pack, and 3 cougars in 1 family group. Grizzly bears were more likely located inside the YNP boundary during the pre-hunt period and north of the boundary once hunting began. The cougar family tended to be found outside YNP during the pre-hunt period and moved inside YNP when hunting began. Wolves did not significantly change their movement patterns during the pre-hunt and hunting periods. Qualitative information on elk (Cervus elaphus) indicated they moved into YNP once hunting started, suggesting that cougars followed living prey or responded to hunting activity, grizzly bears focused on dead prey (e.g., gut piles, crippled elk), and wolves may have taken advantage of both. Measures of association (Jacob's Index) were positive within carnivore species but inconclusive among species. Further collaborative research and the use of new technologies such as Global Positioning System (GPS) telemetry collars will advance our ability to understand these species, the carnivore community and its interactions, and human influences on carnivores.

  11. Place Of Hunting Tourism In The Structure Of Modern Tourism Types

Tourism hunting covers six types of tourism: subsistence indigenoushunting, traditional hunting, commercial hunting, recreational-sport hunting,integrated hunting, and optimum level game maintenance hunting. Huntingtourists should be classified into three distinct categories: large gamehunting tourists (for whom what matters is adventure and trophies, small gamehunting tourists (interested in the hunting experience, and experiencedhunting tourists (characterised by the use of frontal charge guns or arrowshooting.

  12. The magnitude and selectivity of natural and multiple anthropogenic mortality causes in hunted brown bears.

    2009-05-01

    1. The population dynamic and evolutionary effects of harvesting are receiving growing attention among biologists. Cause-specific estimates of mortality are necessary to determine and compare the magnitude and selectivity of hunting and other types of mortalities. In addition to the logistic and financial constraints on longitudinal studies, they are complicated by the fact that nonhunting mortality in managed populations usually consists of a mix of natural and human-caused factors. 2. We used multistate capture-recapture (MCR) models to estimate cause-specific survival of brown bears (Ursus arctos) in two subpopulations in Sweden over a 23-year period. In our analysis, we distinguished between legal hunting and other sources of mortality, such as intraspecific predation, accidents, poaching, and damage control removals. We also tested whether a strong increase in harvest quotas after 1997 in one of the subpopulations affected vulnerability to legal hunting. 3. Although only a fraction of mortalities other than legal hunting could be considered natural, this group of causes showed a general pattern of demographic selectivity expected from natural mortality regimes in populations of long-lived species, namely greater vulnerability of young animals. On the other hand, demographic effects on hunting vulnerability were weak and inconsistent. Our findings support the assumption that hunting and other mortalities were additive. 4. As expected, an increase in hunting pressure coincided with a correspondingly large increase in vulnerability to hunting in the affected subpopulation. Because even unbiased harvest can lead to selective pressures on life-history traits, such as size at primiparity, increasing harvest quotas may not only affect population growth directly, but could also alter optimal life-history strategies in brown bears and other carnivores. 5. Legal hunting is the most conveniently assessed and the most easily managed cause of mortality in many wild

  14. “Redneck, Barbaric, Cashed up Bogan? I Don’t Think So”: Hunting and Nature in Australia

    Directory of Open Access Journals (Sweden)

    Michael Adams

    2013-05-01

    Full Text Available Hunting is a controversial activity in Australia, and much debated in international research. Positions range from ‘the first hunters were the first humans’ to the ‘meat is murder’ argument. There is, however, very little research on non-Indigenous hunting in Australia, particularly on the social aspects, but also on biological and ecological issues. In contrast to a general lack of research on non-Indigenous hunting, there is extensive literature on Indigenous hunting. This paper reviews initial research exploring hunting participation and motivation in Australia, as a window into further understanding connections between humans, non-humans and place. My focus is on an analysis of hunting as cultural involvement in nature. Is it a cruel, archaic and redundant practice; or a respectful relationship between and among humans and non- humans which can reorient us to our emerging recombinant ecologies?

    2015-04-01

    Full Text Available This project shows a creative approach to the familiar scavenger hunt game. It involved the implementation of an iPhone application, HUNT, with Augmented Reality (AR capability for the users to play the game as well as an administrative website that game organizers can use to create and make available games for users to play. Using the HUNT mobile app, users will first make a selection from a list of games, and they will then be shown a list of objects that they must seek. Once the user finds a correct object and scans it with the built-in camera on the smartphone, the application will attempt to verify if it is the correct object and then display associated multi-media AR content that may include images and videos overlaid on top of real world views. HUNT not only provides entertaining activities within an environment that players can explore, but the AR contents can serve as an educational tool. The project is designed to increase user involvement by using a familiar and enjoyable game as a basis and adding an educational dimension by incorporating AR technology and engaging and interactive multimedia to provide users with facts about the objects that they have located

    In 1986, the contamination of some regions in Austria by 137 Cs, due to the Chernobyl accident was relatively high. Among other 137 Cs is taken up by people by the consumption of game. In an area of Lower Austria which is relatively heavily contaminated by Chernobyl fallout since 1986 the 137 Cs-contamination of meat of game-animals was measured every year. Clear differences arose in the load of the single game species whose causes just like the temporal changes are discussed. The highest 137 Cs activity concentration was with 5243 Bq/kg measured on a wild boar. With this activity concentration an annual effective dose of only 0,06 mSv can be estimated for an annual average consumption of one kilogram meat of wild boar. (orig.) [de

    Full Text Available Although prohibited, hunting is widely practiced by rural populations settled along the Transamazon Highway. A diagnostic of subsistence hunting was conducted in 1997 in the Uruará district of Brazil. Beat, hide and trap were the three main hunting techniques, and each one targeted a specific type of game. Although these techniques were rudimentary, 62% of the hunts were successful. Hunters kept their movements within five kilometers at most from their homes, thus covering an 80 km² area. The number of species caught was low: pacas (Agouti paca, deer (Mazama sp. and collared peccaries (Tayassu tajacu provided more than 70% of game meat. The red mazama (Mazama americana, the favorite species, and the paca underwent the highest hunting pressure. In addition to social and ludic roles, hunting had a real nutritional value. Mean daily game meat consumption ranged from 36 to 45.9 g per person (i.e. 13.1–16.7 kg per person per year, depending on the origin of the hunters (urban or rural, respectively. Game hunting did not seem to be the main factor for loss of biodiversity, which might rather result from the transformation of the forest ecosystem into agricultural zones: the habitats were parceled out, generating a reduction in the biodiversity. Community management of wildlife and development of new activities such as breeding of wild animals could help preserve natural resources.

  1. Applying principles from the game theory to acute stroke care: Learning from the prisoner's dilemma, stag-hunt, and other strategies.

    Saposnik, Gustavo; Johnston, S Claiborne

    2016-04-01

    Acute stroke care represents a challenge for decision makers. Decisions based on erroneous assessments may generate false expectations of patients and their family members, and potentially inappropriate medical advice. Game theory is the analysis of interactions between individuals to study how conflict and cooperation affect our decisions. We reviewed principles of game theory that could be applied to medical decisions under uncertainty. Medical decisions in acute stroke care are usually made under constrains: short period of time, with imperfect clinical information, limit understanding about patients and families' values and beliefs. Game theory brings some strategies to help us manage complex medical situations under uncertainty. For example, it offers a different perspective by encouraging the consideration of different alternatives through the understanding of patients' preferences and the careful evaluation of cognitive distortions when applying 'real-world' data. The stag-hunt game teaches us the importance of trust to strength cooperation for a successful patient-physician interaction that is beyond a good or poor clinical outcome. The application of game theory to stroke care may improve our understanding of complex medical situations and help clinicians make practical decisions under uncertainty. © 2016 World Stroke Organization.

  6. Modelling the costs of natural hazards in games

    2012-04-01

    City are looked for today, including a development at the University of Torino called SimTorino, which simulates the development of the city in the next 20 years. The connection to another games genre as video games, the board games, will be investigated, since there are games on construction and reconstruction of a cathedral and its tower and a bridge in an urban environment of the middle ages based on the two novels of Ken Follett, "Pillars of the Earth" and "World Without End" and also more recent games, such as "Urban Sprawl" or the Romanian game "Habitat", dealing with the man-made hazard of demolition. A review of these games will be provided based on first hand playing experience. In games like "World without End" or "Pillars of the Earth", just like in the recently popular games of Zynga on social networks, construction management is done through providing "building" an item out of stylised materials, such as "stone", "sand" or more specific ones as "nail". Such approach could be used also for retrofitting buildings for earthquakes, in the series of "upgrade", not just for extension as it is currently in games, and this is what our research is about. "World without End" includes a natural disaster not so analysed today but which was judged by the author as the worst of manhood: the Black Death. The Black Death has effects and costs as well, not only modelled through action cards, but also on the built environment, by buildings remaining empty. On the other hand, games such as "Habitat" rely on role playing, which has been recently recognised as a way to bring games theory to decision making through the so-called contribution of drama, a way to solve conflicts through balancing instead of weighting, and thus related to Analytic Hierarchy Process. The presentation aims to also give hints on how to design a game for the problem of earthquake retrofit, translating the aims of the actors in such a process into role playing. Games are also employed in teaching of urban

  7. Model for Educational Game Using Natural User Interface

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Natural User Interface (NUI is a new approach that has become increasingly popular in Human-Computer Interaction (HCI. The use of this technology is widely used in almost all sectors, including the field of education. In recent years, there are a lot of educational games using NUI technology in the market such as Kinect game. Kinect is a sensor that can recognize body movements, postures, and voices in three dimensions. It enables users to control and interact with game without the need of using game controller. However, the contents of most existing Kinect games do not follow the standard curriculum in classroom, thus making it do not fully achieve the learning objectives. Hence, this research proposes a design model as a guideline in designing educational game using NUI. A prototype has been developed as one of the objectives in this study. The prototype is based on proposed model to ensure and assess the effectiveness of the model. The outcomes of this study conclude that the proposed model contributed to the design method for the development of the educational game using NUI. Furthermore, evaluation results of the prototype show a good response from participant and in line with the standard curriculum.

    2018-01-01

    Full Text Available We summarize information provided by some recent scientific studies in relation to the opinions, views and attitudes of Spanish hunters regarding hunting and its management. In particular, we discuss the different functions (economic, ecological and social that hunters attribute to hunting, as well as their moral judgements associated with the different motives for hunting. In addition, we explore how hunters value different game management tools (including predator control, releases of farm-reared animals and the regulation of hunting pressure, and we discuss how such valuations affect their decision-making. Finally, we assess potential future trends of hunting, as expressed by the hunters themselves.

  12. How much land is needed for feral pig hunting in Hawai'i?

    Science.gov (United States)

    Hess, Steven C.; Jacobi, James D.

    2014-01-01

    Hunting is often considered to be incompatible with conservation of native biota and watershed functions in Hawai'i. Management actions for conservation generally exclude large non-native mammals from natural areas, thereby reducing the amount of land area available for hunting activities and the maintenance of sustainable game populations. An approach which may be useful in addressing the necessary minimum amount of land area allocated for hunting in Hawai'i is to determine the amount of land area necessary for sustaining populations of hunted animals to meet current levels harvested by the public. We ask: What is the total amount of land necessary to provide sustained-yield hunting of game meat for food at the current harvest level on Hawai'i Island if only feral pigs (Sus scrofa) were to be harvested? We used a simplistic analysis to estimate that 1 317.6 km2-1 651.4 km2 would be necessary to produce 187 333.6 kg of feral pig meat annually based on the range of dressed weight per whole pig, the proportion of a pig population that can be sustainably removed annually, and the density of pig populations in the wild. This amount of area comprises 12.6-15.8% of the total land area of Hawai'i Island, but more likely represents 27.6-43.5% of areas that may be compatible with sustained-yield hunting.

  17. Learning the Rules of the Game: The Nature of Game and Classroom Supports When Using a Concept-Integrated Digital Physics Game in the Middle School Science Classroom

    Science.gov (United States)

    Stewart, Phillip Michael, Jr.

    Games in science education is emerging as a popular topic of scholarly inquiry. The National Research Council recently published a report detailing a research agenda for games and science education entitled Learning Science Through Computer Games and Simulations (2011). The report recommends moving beyond typical proof-of-concept studies into more exploratory and theoretically-based work to determine how best to integrate games into K-12 classrooms for learning , as well as how scaffolds from within the game and from outside the game (from peers and teachers) support the learning of applicable science. This study uses a mixed-methods, quasi-experimental design with an 8th grade class at an independent school in southern Connecticut to answer the following questions: 1. What is the nature of the supports for science content learning provided by the game, the peer, and the teacher, when the game is used in a classroom setting? 2. How do the learning gains in the peer support condition compare to the solo play condition, both qualitatively and quantitatively? The concept-integrated physics game SURGE (Scaffolding Understanding through Redesigning Games for Education) was selected for this study, as it was developed with an ear towards specific learning theories and prior work on student understandings of impulse, force, and vectors. Stimulated recall interviews and video observations served as the primary sources and major patterns emerged through the triangulation of data sources and qualitative analysis in the software QSR NVivo 9. The first pattern which emerged indicated that scaffolding from within the game and outside the game requires a pause in game action to be effective, unless that scaffolding is directly useful to the player in the moment of action. The second major pattern indicated that both amount and type of prior gaming experience has somewhat complex effects on both the uses of supports and learning outcomes. In general, a high correlation was found

    2014-12-15

    Rates of trichinellosis have declined significantly in the United States due to improved pork production practices and public awareness of the danger of eating raw or undercooked pork. In April 2011, the Minnesota Department of Health received a report of presumptive trichinellosis in a 50-year-old man with a history of wild boar consumption. A public health investigation was initiated. Medical record reviews and patient and family interviews were conducted. Trichinella species serology was performed on patient and family serum samples, and larval identification was attempted on clinical specimens and meat samples. The index patient harvested a wild boar from an Iowa game farm; he processed the meat after returning home and developed gastrointestinal symptoms 2 days later. Four days after his illness onset, all 5 family members consumed a roast from the boar. The index patient sought healthcare 4 times after illness onset before being definitively diagnosed with trichinellosis. Following initiation of albendazole therapy, the index patient developed atrial fibrillation. One additional family member who processed the raw meat was diagnosed with trichinellosis. Trichinella spiralis larvae were identified in wild boar meat samples. Trichinellosis has long been recognized as a potential hazard of consuming undercooked wild carnivore meat, and historically has been associated with consumption of pork from domestic swine, but may be unfamiliar to practicing clinicians in the United States. Education of hunters and the broader population on the potential for trichinellosis and the importance of proper handling and cooking meat from wild or free-range animals needs to be reinforced.

    Full Text Available In the last decades, Natural Language Processing (NLP has obtained a high level of success. Interactions between NLP and Serious Games have started and some of them already include NLP techniques. The objectives of this paper are twofold: on the one hand, providing a simple framework to enable analysis of potential uses of NLP in Serious Games and, on the other hand, applying the NLP framework to existing Serious Games and giving an overview of the use of NLP in pedagogical Serious Games. In this paper we present 11 serious games exploiting NLP techniques. We present them systematically, according to the following structure:  first, we highlight possible uses of NLP techniques in Serious Games, second, we describe the type of NLP implemented in the each specific Serious Game and, third, we provide a link to possible purposes of use for the different actors interacting in the Serious Game.

  1. The Legal Nature of Video Games – Adapting Copyright Law to Multimedia

    Directory of Open Access Journals (Sweden)

    Julian Simon Stein

    2015-06-01

    Full Text Available In Copyright Law, video games are still a contentious matter. The multimedia nature of games brings up the question on how to define their legal nature. While there are several original underlying works in video games such as computer programs, artistic works, musical works, dramatic works etc., video games enjoy protection as films or audiovisual works respectively in many jurisdictions, making video games an arrangement of a multiplicity of works. However, some have argued to define video games as a single 'multimedia work' rather than a product of many works of copyright.This article analyses the different types of original and derivative works contained in video games before evaluating the necessity and feasibility of a multimedia category of work, arguing in favour of the current system.

    2017-01-01

    Parkinson's Disease rehabilitation can be long and boring being difficult to maintain patient engagement on therapy programs. Novel technologies are allowing computer games to be played throught natural interfaces. This paper presents the development and assessment of a system of serious games for fine motor skills rehabilitation using natural interfaces. The games were assessed throught a questionnaire that evaluated the game experience through seven components: immersion, flow, competence, tension, challenge and positive and negative affect. In addition, a conceptual framework for development of serious games for fine motor skills rehabilitation was proposed. The results from the quantitative questionnaire suggested that the player experience was positive on all components assessed. Also, player experience between the three games was statistically the same, implying that the games can be used with consistency in a physical therapy rehabilitation program.

  3. Impact of environmental diversity of hunting complexes in the Lublin region on ontogenetic quality indicators in roe deer (Capreolus capreolus).

    2018-01-01

    Populations of game are not confined to single ecosystems but function within higher-order units, e.g. ecological landscape. The basis for the establishment of the hunting complexes was the assumption that the existing game hunting grounds, i.e. the basic units implementing game management, are too small and do not cover the natural areas inhabited by game populations. Roe deer are flexible species and easily adapt to various site conditions, so they inhabit many different habitats, from large forest complexes, through small in-field tree stands and shrubs, to treeless grounds and field monocultures. The aim of the study was to determine a possible impact of environmental conditions prevailing in the hunting complexes of the Regional Directorate of State Forests (RDLP in Lublin) on the ontogenetic quality of roe deer. The study was conducted on 518 European roe deer ( Capreolus capreolus ) aged from 4 to 7 years (379 bucks and 139 does) harvested within hunting seasons 2010/2011-2013/2014. The results have shown that animals originating from areas with greater forest cover and denser stands are characterised by lower values of the mean ontogenetic quality parameters (carcase weight, kidney fat index, chest girth, weight of antlers) in comparison with animals from typical agricultural areas with fragmented forest complexes. These results indicate that, even in the case of such a eurytopic species as the roe deer, the ontogenetic quality differs between individual hunting complexes. The study has proved that strategies for hunting management of the roe deer should take into account the impact of the landscape structure, which provides a rationale behind creation of hunting complexes.

  4. Deforestation and hunting effects on wildlife across Amazonian indigenous lands

    Directory of Open Access Journals (Sweden)

    Pedro de Araujo Lima. Constantino

    2016-06-01

    Full Text Available Deforestation and hunting are main wildlife threats in Amazonia, affecting the ecosystem and dwellers that rely on game meat. Data from 9109 hunted animals from 35 villages of 8 Pano indigenous lands in Brazilian Amazonia were used to build 4 indicators of wildlife status based on ecological models and to analyze the effects of deforestation, hunting pressure, and socioeconomic aspects on wildlife variation. Although variation in wildlife status indicated depletion in certain locations, hunters from most villages continued to hunt their preferred game after decades of intensive hunting. Indigenous hunting resulted in local depletion of species because of the dispersal of animals away from the source of hunting. This local effect can be explained by the permanent hunting of wildlife in the region, the behavior of Pano hunters, and the design and scale of this study analysis. Regionally, however, deforestation and associated factors are the cause of reduced population density and hunting success, extirpating sensitive species. Roads exacerbated hunting effects through disturbance, encroachment, and provision of access to livestock meat at markets. To avoid local depletion, indigenous people must review their subsistence hunting practices, whereas to achieve regional wildlife conservation and to maintain indigenous societies in Amazonia, wildlife habitat loss should be limited.

    Full Text Available In the Republic of Croatia, game meat is consumed far less than meat of domestic animals. Yearly game meat consumption amounts to only 0.55 kg per household member. Consumers prefer meat of domestic animals, because it is cheaper, not paying attention to specific nutritive advantages of game meat. A research on the game meat market and consumers’ preferences was carried out on 101 examinees, chosen among inhabitants of Slavonia and Baranja. The majority of questioned inhabitants did consume game meat (92%, of whom 66% consider game meat to be of better quality than meat of domestic animals. Significant number of examinees considers game meat as healthy food, being also convinced that game was healthier to consume if hunted in their natural environment, than if reared on specialized farms (90%. Irrespective of quality, only 22% of examinees buy game meat, and 51% think such meat is too expensive. This is the main reason why consumers have game meat only once a month (51%. Taking into consideration monthly income of their respective household, 58% of examinees can afford game meat only once a month, and, if having an opportunity, they would opt for meat of roe deer (55% and rabbit (25%. When asked what would stimulate the game meat market in Croatia, 56% of examinees believe this could be achieved by lowering of prices, 27% think the issue could be addressed by opening of specialty stores, and only 17% opted for more aggressive marketing activities.

  8. Using systems gaming to explore decision-making under uncertainty in natural hazard crises

    Science.gov (United States)

    McCaughey, Jamie W.; Finnigan, David

    2017-04-01

    Faced with uncertain scientific forecasts of a potential hazard, it is perhaps natural to wait and see. As we wait, uncertainties do decrease, but so do our options to minimise impacts of the hazard. This tradeoff is fundamental to preparing for natural hazards, yet difficult to communicate. Interactive systems gaming is one promising way forward. We are developing in-person interactive games, drawing on role-playing and other table-top scenario exercises in natural hazards, as well as on game-based modeling of complex systems. Our games model an unfolding natural hazard crisis (such as volcanic unrest or an approaching typhoon) as a complex social-physical system. Participants take on the roles of diverse stakeholder groups (including government, scientists, media, farmers, city residents, and others) with differing expertise, responsibilities, and priorities. Interactions among these groups play out in a context of decreasing scientific uncertainty and decreasing options for actions to reduce societal risk. Key design challenges are (1) to engage players without trivialising the real-world context; (2) to provide the right level of guidance for players to navigate the system; and (3) to enable players to face realistic tradeoffs and see realistic consequences of their choices, without feeling frustrated that the game is set up for them to fail. We will first prototype the games with general public and secondary-school participants, then adjust this for specialist groups working in disaster management. We will illustrate participatory systems gaming techniques in our presentation 'A toolkit of systems gaming techniques' in the companion EGU session EOS6: 'Perform! A platform to discuss art & science projects with live presentation'.

    the hunter the solicited new game if he has completed his ritual duties and has not broken the prescribed hunting rules. The Loojil Ts'oon does not only represent the continuity and regeneration of animals, that is, fauna as a resource, but also of the whole hunting cycle. The hunter does so to maintain and recreate order and equilibrium in one's relationship with nature as a whole, with the rest of one's social group, and with oneself. Thus, hunting transcends the exclusively material dimension of a subsistence activity.

  13. The influence of action video game playing on eye movement behaviour during visual search in abstract, in-game and natural scenes.

    2017-02-01

    Action game playing has been associated with several improvements in visual attention tasks. However, it is not clear how such changes might influence the way we overtly select information from our visual world (i.e. eye movements). We examined whether action-video-game training changed eye movement behaviour in a series of visual search tasks including conjunctive search (relatively abstracted from natural behaviour), game-related search, and more naturalistic scene search. Forty nongamers were trained in either an action first-person shooter game or a card game (control) for 10 hours. As a further control, we recorded eye movements of 20 experienced action gamers on the same tasks. The results did not show any change in duration of fixations or saccade amplitude either from before to after the training or between all nongamers (pretraining) and experienced action gamers. However, we observed a change in search strategy, reflected by a reduction in the vertical distribution of fixations for the game-related search task in the action-game-trained group. This might suggest learning the likely distribution of targets. In other words, game training only skilled participants to search game images for targets important to the game, with no indication of transfer to the more natural scene search. Taken together, these results suggest no modification in overt allocation of attention. Either the skills that can be trained with action gaming are not powerful enough to influence information selection through eye movements, or action-game-learned skills are not used when deciding where to move the eyes.

    Full Text Available Researchers are increasingly exploring the role of emotions in interactive decision‐making.  Recent theories have focused on the interpersonal effects of emotions—the influence of the decisionmaker’s expressed emotions on observers’ decisions and judgments. In this paper, we examine  whether people assess others’ risk preferences on the basis of their emotional states, whether this  affects their own behavior, and how this assessment matches others’ actual behavior. To test these  ideas, we used an experimental Stag Hunt game (n = 98, and included non‐trivial financial  consequences. Participants were told (truthfully that their counterparts’ previous task had left them  happy, fearful, or emotionally neutral. People who were told their counterparts were fearful  reported that they expected less risky decisions from these counterparts than people told their  counterparts were neutral or happy. As a result, given that the Stag Hunt is a coordination game,  these participants were themselves less risky. Interestingly, these participants’ expectations were  not accurate; thus, coordination failed, and payoffs were low. This raises the possibility of a “curse  of knowledge” whereby one player’s erroneous beliefs about the effects of the counterpart’s  emotional state leads the first player to make poor action choices.

  15. Stochastic noncooperative and cooperative evolutionary game strategies of a population of biological networks under natural selection.

    Chen, Bor-Sen; Yeh, Chin-Hsun

    2017-12-01

    We review current static and dynamic evolutionary game strategies of biological networks and discuss the lack of random genetic variations and stochastic environmental disturbances in these models. To include these factors, a population of evolving biological networks is modeled as a nonlinear stochastic biological system with Poisson-driven genetic variations and random environmental fluctuations (stimuli). To gain insight into the evolutionary game theory of stochastic biological networks under natural selection, the phenotypic robustness and network evolvability of noncooperative and cooperative evolutionary game strategies are discussed from a stochastic Nash game perspective. The noncooperative strategy can be transformed into an equivalent multi-objective optimization problem and is shown to display significantly improved network robustness to tolerate genetic variations and buffer environmental disturbances, maintaining phenotypic traits for longer than the cooperative strategy. However, the noncooperative case requires greater effort and more compromises between partly conflicting players. Global linearization is used to simplify the problem of solving nonlinear stochastic evolutionary games. Finally, a simple stochastic evolutionary model of a metabolic pathway is simulated to illustrate the procedure of solving for two evolutionary game strategies and to confirm and compare their respective characteristics in the evolutionary process.

In an area of Lower Austria which is relatively heavily contaminated by Chernobyl fallout since 1986 the {sup 137}Cs-contamination of meat of game-animals was measured every year. Clear differences arose in the load of the single game species whose causes just like the temporal changes are discussed. The highest {sup 137}Cs activity concentration was with 5243 Bq/kg measured on a wild boar. With this activity concentration an annual effective dose of only 0,06 mSv can be estimated for an annual average consumption of one kilogram meat of wild boar. (orig.) [German] Druch den Reaktor-Unfall in Tschernobyl wurde Oesterreich gebietsweise relativ stark mit {sup 137}Cs kontaminiert.

    2015-01-01

    Internet Gaming Disorder has been added as a research diagnosis in section III for the DSM-V. Previous findings from neuroscientific research indicate an enhanced motivational attention toward cues related to computer games, similar to findings in substance-related addictions. On the other hand in clinical observational studies tolerance effects are reported by patients with Internet Gaming disorder. In the present study we investigated whether an enhanced motivational attention or tolerance effects are present in patients with Internet Gaming Disorder. A clinical sample from the Outpatient Clinic for Behavioral Addictions in Mainz, Germany was recruited, fulfilling the diagnostic criteria for Internet Gaming Disorder. In a semi-natural EEG design participants played a computer game during the recording of event-related potentials to assess reward processing. The results indicated an attenuated P300 for patients with Internet Gaming Disorder in response to rewards in comparison to healthy controls, while the latency of N100 was prolonged and the amplitude of N100 was increased. Our findings support the hypothesis that tolerance effects are present in patients with Internet Gaming Disorder, when actively playing computer games. In addition, the initial orienting toward the gaming reward is suggested to consume more capacity for patients with Internet Gaming Disorder, which has been similarly reported by other studies with other methodological background in disorders of substance-related addictions.

    Full Text Available The impacts of unregulated sport hunting can severely affect populations of target game species. Because hunting in Brazil is limited by law, obtaining data on illegal sport hunting in this country is challenging. We used an unusual online resource, YouTube™, to detect the occurrence of sport hunting in Brazil, measure the impacts of the activity on the main Brazilian game species and biomes, evaluate the opinions of hunters and internet users on sport hunting, and discuss the need for policy interventions in wildlife conservation in this country. We found 383 videos related to Brazilian sport hunting on YouTube™, accounting for more than 15 million views. Most videos were produced in the Cerrado (Brazilian savannah and approximately 70% of them depicted events of pursuit and killing of wild animals, especially lowland pacas (Cuniculus paca and armadillos (Family Dasypodidae. Videos were posted primarily in July and December, coinciding with the two main Brazilian vacation periods. Furthermore, the shotguns identified on videos show that sport hunters expend large sums of money to undertake their hunts. These results indicate that Brazilian sport hunters are possibly wealthier urban residents who travel to rural areas to hunt, contrasting with previous hunting studies in the country. Most viewers declared themselves in favor of sport hunting in comments (n = 2893 and ratings (n = 36,570 of the videos. Discussions generated by comments suggest that Brazilian sport hunters employ several informal management strategies to maintain game species stocks for future hunting and intensely question the restrictions of Brazilian environmental policies. Our results demonstrate that solutions are needed for the regulation of sport hunting in Brazil. Government actions, whether to increase surveillance or legalize hunting programs, should take into account the opinions of sport hunters and their perceptions on hunting dynamics to support effective policy

    Although the cheetah is recognised as the fastest land animal, little is known about other aspects of its notable athleticism, particularly when hunting in the wild. Here we describe and use a new tracking collar of our own design, containing a combination of Global Positioning System (GPS) and inertial measurement units, to capture the locomotor dynamics and outcome of 367 predominantly hunting runs of five wild cheetahs in Botswana. A remarkable top speed of 25.9 m s(-1) (58 m.p.h. or 93 km h(-1)) was recorded, but most cheetah hunts involved only moderate speeds. We recorded some of the highest measured values for lateral and forward acceleration, deceleration and body-mass-specific power for any terrestrial mammal. To our knowledge, this is the first detailed locomotor information on the hunting dynamics of a large cursorial predator in its natural habitat.

    Natural and artificially produced radionuclides were determined in meat and bones of deer, boar and wild hare on hunting areas in Vojvodina (Serbia). Seven natural radionuclides and three fission products ( 235 U, 238 U, 232 Th, 7 Be, 144 Ce, 40 K, 106 Ru, 134 Cs, 137 Cs, 90 Sr) were identified in the investigated game samples. The highest contents of the radionuclides were found in bones and meat of boars and the lowes in the bones of fallow-deer. The predominant radionuclides were 40 K and 90 Sr, for all of the investigated animals and their contents depended strongly upon the game species, organ type and the age of the animal. The examined breeding sites did not appear to have any effect on the radionuclide contents in game, which indicates that the radionuclides were uniformly distributed over the habitat.

  10. Toward brain correlates of natural behavior: fMRI during violent video games.

    Science.gov (United States)

    Mathiak, Klaus; Weber, René

    2006-12-01

    Modern video games represent highly advanced virtual reality simulations and often contain virtual violence. In a significant amount of young males, playing video games is a quotidian activity, making it an almost natural behavior. Recordings of brain activation with functional magnetic resonance imaging (fMRI) during gameplay may reflect neuronal correlates of real-life behavior. We recorded 13 experienced gamers (18-26 years; average 14 hrs/week playing) while playing a violent first-person shooter game (a violent computer game played in self-perspective) by means of distortion and dephasing reduced fMRI (3 T; single-shot triple-echo echo-planar imaging [EPI]). Content analysis of the video and sound with 100 ms time resolution achieved relevant behavioral variables. These variables explained significant signal variance across large distributed networks. Occurrence of violent scenes revealed significant neuronal correlates in an event-related design. Activation of dorsal and deactivation of rostral anterior cingulate and amygdala characterized the mid-frontal pattern related to virtual violence. Statistics and effect sizes can be considered large at these areas. Optimized imaging strategies allowed for single-subject and for single-trial analysis with good image quality at basal brain structures. We propose that virtual environments can be used to study neuronal processes involved in semi-naturalistic behavior as determined by content analysis. Importantly, the activation pattern reflects brain-environment interactions rather than stimulus responses as observed in classical experimental designs. We relate our findings to the general discussion on social effects of playing first-person shooter games. (c) 2006 Wiley-Liss, Inc.

  14. Hunting Motifs in Situla Art

    Andrej Preložnik

    2013-07-01

    Full Text Available Situla art developed as an echo of the toreutic style which had spread from the Near East through the Phoenicians, Greeks and Etruscans as far as the Veneti, Raeti, Histri, and their eastern neighbours in the region of Dolenjska (Lower Carniola. An Early Iron Age phenomenon (c. 600—300 BC, it rep- resents the major and most arresting form of the contemporary visual arts in an area stretching from the foot of the Apennines in the south to the Drava and Sava rivers in the east. Indeed, individual pieces have found their way across the Alpine passes and all the way north to the Danube. In the world and art of the situlae, a prominent role is accorded to ani- mals. They are displayed in numerous representations of human activities on artefacts crafted in the classic situla style – that is, between the late 6th  and early 5th centuries BC – as passive participants (e.g. in pageants or in harness or as an active element of the situla narrative. The most typical example of the latter is the hunting scene. Today we know at least four objects decorat- ed exclusively with hunting themes, and a number of situlae and other larger vessels where hunting scenes are embedded in composite narratives. All this suggests a popularity unparallelled by any other genre. Clearly recognisable are various hunting techniques and weapons, each associated with a particu- lar type of game (Fig. 1. The chase of a stag with javelin, horse and hound is depicted on the long- familiar and repeatedly published fibula of Zagorje (Fig. 2. It displays a hound mauling the stag’s back and a hunter on horseback pursuing a hind, her neck already pierced by the javelin. To judge by the (so far unnoticed shaft end un- der the stag’s muzzle, the hunter would have been brandishing a second jave- lin as well, like the warrior of the Vače fibula or the rider of the Nesactium situla, presumably himself a hunter.

    Full Text Available While hunting in traditional societies, was most commonly practised as a profession, for food, sports or entertainment, it was fully a part of Ottoman State organization as a military exercise or war game. From the first Ottoman rulers, there has been hunting institution in the palace. An organized hunting institution, regular hunting practices and the number of hunted animals had been perceived as the symbols of power of the ruler. Hunting organization was instrumental in identifying the situations of the country and people, inspecting government officials and listening to people’s problems. In this respect, the meaning of hunting ceremony gains great importance. Hunting bird-growing organization in Ottoman Empire palace had been institutionalized since early years. Its provincial administration was created for particular sanjaks. The structure of provincial hunting organization was organized in the form of taşra doğancıları (provincial falconers or hawkers, sayyad (hunters, yavrucu (fledgeling careres, yuvacı (nest carers, kayacı (carer of nest rocks, görenceci (bird observers, tuzakçı (bird catchers. There are records in Ottoman archives about this units concerning their organization, numbers, how they were spread and how the duties were passed from father to son. In this study, in the 16th century provincial Ottoman hunting organization and services in Silistra has been throughly examined, using archive documents.

    Electronic medical records (EMRs) are increasingly repurposed for activities beyond clinical care, such as to support translational research and public policy analysis. To mitigate privacy risks, healthcare organizations (HCOs) aim to remove potentially identifying patient information. A substantial quantity of EMR data is in natural language form and there are concerns that automated tools for detecting identifiers are imperfect and leak information that can be exploited by ill-intentioned data recipients. Thus, HCOs have been encouraged to invest as much effort as possible to find and detect potential identifiers, but such a strategy assumes the recipients are sufficiently incentivized and capable of exploiting leaked identifiers. In practice, such an assumption may not hold true and HCOs may overinvest in de-identification technology. The goal of this study is to design a natural language de-identification framework, rooted in game theory, which enables an HCO to optimize their investments given the expected capabilities of an adversarial recipient. We introduce a Stackelberg game to balance risk and utility in natural language de-identification. This game represents a cost-benefit model that enables an HCO with a fixed budget to minimize their investment in the de-identification process. We evaluate this model by assessing the overall payoff to the HCO and the adversary using 2100 clinical notes from Vanderbilt University Medical Center. We simulate several policy alternatives using a range of parameters, including the cost of training a de-identification model and the loss in data utility due to the removal of terms that are not identifiers. In addition, we compare policy options where, when an attacker is fined for misuse, a monetary penalty is paid to the publishing HCO as opposed to a third party (e.g., a federal regulator). Our results show that when an HCO is forced to exhaust a limited budget (set to $2000 in the study), the precision and recall of the

    Full Text Available Rational management of hunting and gathering: An Aristotelian entelechy or a chimera? Since the dawn of time, consumption of animal protein has been crucially important to the evolution of humans. Cooperative hunting is an Evolutionarily Stable Strategy from the time when Palaeolithic hunters specialized in the pursuit of large animals. The entire process involves making decisions related to game management, some of which are still used by contemporary hunter-gatherers. In these societies, which still practice subsistence hunting, the composition of their diets and the exploitation techniques employed are explained by the theoretical underpinnings contained in the Optimal Foraging Theory (OFT. In order to test this theory, we have taken into account four decisions involving the adoption of different management strategies by hunter-gatherers: I what to eat, II where and how to look for food, III the most appropriate size and composition of the group of hunter-gatherers and IV the most efficient guidelines for the handling and distribution of prey. The OFT has been tested several times, and in a high percentage of cases studied, its predictions fit observations made in various hunter-gatherer societies. This means that maximizing catch yields in the short term is their main concern, rather than behaving as ‘cautious predators’ or passively selecting prey according to their size, accessibility and abundance. Such behaviour does not contradict the possibility that hunter-gatherers can act as conservationists, but discards the idea that this is the main focus of their way of life. There is no doubt that indigenous peoples have a wide knowledge of the environment, but it is unclear this knowledge is used to maintain a balance with nature or to be more efficient hunters. It more likely that the presence of sustainable hunting of game is due to low hunting pressure in areas where animal prey is abundant, and is thus an epiphenomenon rather than a

  2. Forest Stakeholder Participation in Improving Game Habitat in Swedish Forests

    2012-07-01

    Full Text Available Although in Sweden the simultaneous use of forests for timber production and game hunting are both of socioeconomic importance it often leads to conflicting interests. This study examines forest stakeholder participation in improving game habitat to increase hunting opportunities as well as redistribute game activities in forests to help reduce browsing damage in valuable forest stands. The data for the study were collected from a nationwide survey that involved randomly selected hunters and forest owners in Sweden. An ordered logit model was used to account for possible factors influencing the respondents’ participation in improving game habitat. The results showed that on average, forest owning hunters were more involved in improving game habitat than non-hunting forest owners. The involvement of non-forest owning hunters was intermediate between the former two groups. The respondents’ participation in improving game habitat were mainly influenced by factors such as the quantity of game meat obtained, stakeholder group, forests on hunting grounds, the extent of risk posed by game browsing damage to the economy of forest owners, importance of bagging game during hunting, and number of hunting days. The findings will help in designing a more sustainable forest management strategy that integrates timber production and game hunting in forests.

  5. Wolves on the hunt: The behavior of wolves hunting wild prey

    Mech, L. David; Smith, Douglas W.; MacNulty, Daniel R.

    2015-01-01

    The interactions between apex predators and their prey are some of the most awesome and meaningful in nature—displays of strength, endurance, and a deep coevolutionary history. And there is perhaps no apex predator more impressive and important in its hunting—or more infamous, more misjudged—than the wolf. Because of wolves’ habitat, speed, and general success at evading humans, researchers have faced great obstacles in studying their natural hunting behaviors. The first book to focus explicitly on wolf hunting of wild prey, Wolves on the Hunt seeks to fill these gaps in our knowledge and understanding. Combining behavioral data, thousands of hours of original field observations, research in the literature, a wealth of illustrations, and—in the e-book edition and online—video segments from cinematographer Robert K. Landis, the authors create a compelling and complex picture of these hunters. The wolf is indeed an adept killer, able to take down prey much larger than itself. While adapted to hunt primarily hoofed animals, a wolf—or especially a pack of wolves—can kill individuals of just about any species. But even as wolves help drive the underlying rhythms of the ecosystems they inhabit, their evolutionary prowess comes at a cost: wolves spend one-third of their time hunting—the most time consuming of all wolf activities—and success at the hunt only comes through traveling long distances, persisting in the face of regular failure, detecting and taking advantage of deficiencies in the physical condition of individual prey, and through ceaseless trial and error, all while risking injury or death. By describing and analyzing the behaviors wolves use to hunt and kill various wild prey—including deer, moose, caribou, elk, Dall sheep, mountain goats, bison, musk oxen, arctic hares, beavers, and others—Wolves on the Hunt provides a revelatory portrait of one of nature’s greatest hunters.

    2018-03-12

    Much evidence demonstrates the adverse effects of lead ammunition on wildlife, their habitats and human health, and confirms that the use of such ammunition has no place within sustainable hunting. We identify the provisions that define sustainable hunting according to European law and international treaties, together with their guidance documents. We accept the substantial evidence for lead's actual and potential effects on wildlife, habitats and health as persuasive and assess how these effects relate to stated provisions for sustainability and hunting. We evaluate how continued use of lead ammunition negatively affects international efforts to halt loss of biodiversity, sustain wildlife populations and conserve their habitats. We highlight the indiscriminate and avoidable health and welfare impacts for large numbers of exposed wild animals as ethically unsustainable. In societal terms, continued use of lead ammunition undermines public perceptions of hunting. Given the existence of acceptable, non-toxic alternatives for lead ammunition, we conclude that hunting with lead ammunition cannot be justified under established principles of public/international policy and is not sustainable. Changing from lead ammunition to non-toxic alternatives will bring significant nature conservation and human health gains, and from the hunter's perspective will enhance societal acceptance of hunting. Change will create opportunities for improved constructive dialogue between hunting stakeholders and others engaged with enhancing biodiversity and nature conservation objectives.

  7. Sustainable use of forest and hunting resources

    Full Text Available This paper presents the issue of the use of forest and hunting resources in Serbia, with special emphasis on their sustainability. The use of modern technological solutions in terms of sustainable use of forest and hunting resources should be seen through an analysis and evaluation of environmental impacts. The existing machinery used in Serbian forestry cannot respond to the current demands of forestry production. However, the current unfavourable conditions can be significantly improved with appropriate measures. The planning of a network of roads including a number of factors that directly and indirectly affect sustainable use is of great importance for the development of forestry and hunting. Wood biomass in Serbian forests should be used in the manner and to the extent that ensures the sustainability of ecosystems and the production of large quantities of energy. In recent years, non-timber forest products have gained importance, so that the income generated from their use is growing. The impact of newly adopted laws and bylaws in the field of forestry, hunting and the protection of nature and environment will depend primarily on their application, control, execution and possible amendments and adjustments.

    Swiss Telescope at La Silla Very Successful Summary The intensive and exciting hunt for planets around other stars ( "exoplanets" ) is continuing with great success in both hemispheres. Today, an international team of astronomers from the Geneva Observatory and other research institutes [1] is announcing the discovery of no less than eleven new, planetary companions to solar-type stars, HD 8574, HD 28185, HD 50554, HD 74156, HD 80606, HD 82943, HD 106252, HD 141937, HD 178911B, HD 141937, among which two new multi-planet systems . The masses of these new objects range from slightly less than to about 10 times the mass of the planet Jupiter [2]. The new detections are based on measured velocity changes of the stars [3], performed with the CORALIE spectrometer on the Swiss 1.2-m Leonard Euler telescope at the ESO La Silla Observatory , as well as with instruments on telescopes at the Haute-Provence Observatory and on the Keck telescopes on Mauna Kea (Hawaii, USA). Some of the new planets are unusual: * a two-planet system (around the star HD 82943) in which one orbital period is nearly exactly twice as long as the other - cases like this (refered to as "orbital resonance") are well known in our own solar system; * another two-planet system (HD 74156), with a Jupiter-like planet and a more massive planet further out; * a planet with the most elongated orbit detected so far (HD 80606), moving between 5 and 127 million kilometers from the central star; * a giant planet moving in an orbit around its Sun-like central star that is very similar to the one of the Earth and whose potential satellites (in theory, at least) might be "habitable". At this moment, there are 63 know exoplanet candidates with minimum masses below 10 Jupiter masses, and 67 known objects with minimum masses below 17 Jupiter masses. The present team of astronomers has detected about half of these. PR Photo 13a/01 : Radial-velocity measurements of HD 82943, a two-planet system . PR Photo 13b/01 : Radial

    2015-01-01

    Full Text Available Wildlife hunting is an important economic activity that contributes to the subsistence of indigenous peoples and the maintenance of their cultural identity. Changes in indigenous peoples' ways of life affect the way they manage the ecosystems and resources around them, including wildlife populations. This paper explores the relationship between cultural change, or detachment from traditional culture, and hunting behaviour among the Tsimane', an indigenous group in the Bolivian Amazon. We interviewed 344 hunters in 39 villages to estimate their hunting activity and the degree of cultural change among them. We used multilevel analyses to assess the relationships between three different proxies for cultural change at the individual level (schooling, visits to a market town, and detachment from tradition, and the following two independent variables: 1 probability of engaging in hunting (i.e., hunting activity and 2 hunting efficiency with catch per unit effort (CPUE. We found a statistically significant negative association between schooling and hunting activity. Hunting efficiency (CPUE biomass/km was positively associated with visits to a market town, when holding other co-variates in the model constant. Other than biophysical factors, such as game abundance, hunting is also conditioned by social factors (e.g., schooling that shape the hunters' cultural system and impel them to engage in hunting or deter them from doing so.

    Subsistence hunting is a traditional practice providing food and many other goods for households in the Yucatan Peninsula, southeast Mexico. Economic, demographic, and cultural change in this region drive wildlife habitat loss and local extinctions. Improving our understanding about current practices of wildlife use may support better management strategies for conserving game species and their habitat. We aimed to evaluate if wildlife use remained relevant for the subsistence of rural residents of the Yucatan Peninsula, as well as if local hunting practices were related to environmental, geographical, and cultural factors. Fieldwork was done between March 2010 and March 2011. Information was obtained through conversations, interviews, and participant observation. Record forms allowed recording animals hunted, biomass extracted, distance intervals to hunting sites, habitat types and seasonality of wildlife harvests. Data were analyzed using one-way Analysis of Variance, and Generalized Linear Models. Forty-six terrestrial vertebrate species were used for obtaining food, medicine, tools, adornments, pets, ritual objects, and for sale and mitigating damage. We recorded 968 animals taken in 664 successful hunting events. The Great Curassow, Ocellated Turkey, paca, white-tailed deer, and collared peccary were the top harvested species, providing 80.7% of biomass (10,190 kg). The numbers of animals hunted and biomass extracted declined as hunting distances increased from villages. Average per capita consumption was 4.65 ± 2.7 kg/person/year. Hunting frequencies were similar in forested and agricultural areas. Wildlife use, hunting patterns, and technologies observed in our study sites were similar to those recorded in previous studies for rural Mayan and mestizo communities in the Yucatan Peninsula and other Neotropical sites.

    its prevalence suggests that it is both adaptive and that it has an underlying pharmacological explanation. We hypothesize that hallucinogenic plants alter perception in hunting dogs by diminishing extraneous signals and by enhancing sensory perception (most likely olfaction) that is directly involved in the detection and capture of game. If this is true, plant substances also might enhance the ability of dogs to detect explosives, drugs, human remains, or other targets for which they are valued. Copyright © 2015 Elsevier Ireland Ltd.

In the Stag-Hunt and Chicken games, the Win-Stay, Lose-Shift and Grim-Trigger strategies are the ones with the most occurrences. Overall, the pairs that converged quickly ended up at the cooperative outcomes, whereas the ones that were extremely slow to reach convergence ended up at non-cooperative outcomes.

    Conservation scientists are increasingly focusing on the drivers of human behavior and on the implications of various sources of uncertainty for management decision making. Trophy hunting has been suggested as a conservation tool because it gives economic value to wildlife, but recent examples show that overharvesting is a substantial problem and that data limitations are rife. We use a case study of trophy hunting of an endangered antelope, the mountain nyala (Tragelaphus buxtoni), to explore how uncertainties generated by population monitoring and poaching interact with decision making by 2 key stakeholders: the safari companies and the government. We built a management strategy evaluation model that encompasses the population dynamics of mountain nyala, a monitoring model, and a company decision making model. We investigated scenarios of investment into antipoaching and monitoring by governments and safari companies. Harvest strategy was robust to the uncertainty in the population estimates obtained from monitoring, but poaching had a much stronger effect on quota and sustainability. Hence, reducing poaching is in the interests of companies wishing to increase the profitability of their enterprises, for example by engaging community members as game scouts. There is a threshold level of uncertainty in the population estimates beyond which the year-to-year variation in the trophy quota prevented planning by the safari companies. This suggests a role for government in ensuring that a baseline level of population monitoring is carried out such that this level is not exceeded. Our results illustrate the importance of considering the incentives of multiple stakeholders when designing frameworks for resource use and when designing management frameworks to address the particular sources of uncertainty that affect system sustainability most heavily.

  20. Sustainability and Long Term-Tenure: Lion Trophy Hunting in Tanzania.

    Directory of Open Access Journals (Sweden)

    Henry Brink

    Full Text Available It is argued that trophy hunting of large, charismatic mammal species can have considerable conservation benefits but only if undertaken sustainably. Social-ecological theory suggests such sustainability only results from developing governance systems that balance financial and biological requirements. Here we use lion (Panthera leo trophy hunting data from Tanzania to investigate how resource ownership patterns influence hunting revenue and offtake levels. Tanzania contains up to half of the global population of free-ranging lions and is also the main location for lion trophy hunting in Africa. However, there are concerns that current hunting levels are unsustainable. The lion hunting industry in Tanzania is run by the private sector, although the government leases each hunting block to companies, enforces hunting regulation, and allocates them a species-specific annual quota per block. The length of these leases varies and theories surrounding property rights and tenure suggest hunting levels would be less sustainable in blocks experiencing a high turnover of short-term leases. We explored this issue using lion data collected from 1996 to 2008 in the Selous Game Reserve (SGR, the most important trophy hunting destination in Tanzania. We found that blocks in SGR with the highest lion hunting offtake were also those that experienced the steepest declines in trophy offtake. In addition, we found this high hunting offtake and the resultant offtake decline tended to be in blocks under short-term tenure. In contrast, lion hunting levels in blocks under long-term tenure matched more closely the recommended sustainable offtake of 0.92 lions per 1000 km2. However, annual financial returns were higher from blocks under short-term tenure, providing $133 per km2 of government revenue as compared to $62 per km2 from long-term tenure blocks.

    While trophy hunting provides revenue for conservation, it must be carefully managed to avoid negative population impacts, particularly for long-lived species with low natural mortality rates. Trophy hunting has had negative effects on lion populations throughout Africa, and the species serves as an important case study to consider the balance of costs and benefits, and to consider the effectiveness of alternative strategies to conserve exploited species. Age-restricted harvesting is widely recommended to mitigate negative effects of lion hunting, but this recommendation was based on a population model parameterized with data from a well-protected and growing lion population. Here, we used demographic data from lions subject to more typical conditions, including source-sink dynamics between a protected National Park and adjacent hunting areas in Zambia's Luangwa Valley, to develop a stochastic population projection model and evaluate alternative harvest scenarios. Hunting resulted in population declines over a 25-yr period for all continuous harvest strategies, with large declines for quotas >1 lion/concession (~0.5 lion/1,000 km 2 ) and hunting of males younger than seven years. A strategy that combined periods of recovery, an age limit of ≥7 yr, and a maximum quota of ~0.5 lions shot/1,000 km 2 yielded a risk of extirpation lion trophy hunting with a combination of regulations. To implement sustainable trophy hunting while maintaining revenue for conservation of hunting areas, our results suggest that hunting fees must increase as a consequence of diminished supply. These findings are broadly applicable to hunted lion populations throughout Africa and to inform global efforts to conserve exploited carnivore populations. © 2016 by the Ecological Society of America.

  5. Child witch hunts in contemporary Ghana.

    The persecution of children as witches has received widespread reportage in the international mass media. In recent years, hundreds of children have been killed, maimed and abandoned across Africa based on individual and village-level accusations of witchcraft. Despite the media focus, to date, very little systematic study has investigated the phenomenon. In this case study, the persecution of child witches in Ghana is studied to explore the nature and patterns of witch hunts against children in the West African nation. There are no reliable national data on child abuse related to witchcraft accusations in Ghana. For this study, 13 cases of child witch hunts appearing in the local media during 1994-2009 were analyzed. Case summaries were constructed for each incident to help identify the socio-demographic characteristics of assailants and victims, victim-offender relationships, the methods of attacks, the spatial characteristics, as well as the motivations for the attacks. Children branded as witches ranged in age from 1-month-old to 17-years-old, were primarily from poor backgrounds, and lived in rural areas of the country. Accusations of witchcraft and witch assaults were lodged by close family members often through the encouragement of, or in concert with Christian clergymen and fetish priests. Accused witches were physically brutalized, tortured, neglected, and in two cases, murdered. For school-aged children, imputations of witchcraft contributed to stigmatization in both the community and at school, resulting in dropping out. The most frequently expressed reason for persecution of the child was suspicion that the child had used witchcraft to cause the death or illness of family relations or someone in the community. Another reason was suspicion that the child was responsible for the business failure or financial difficulties of a perceived victim. The results of this research are consistent with findings in the witchcraft literature suggesting that seemingly

  6. Differences between Pygmy and Non-Pygmy Hunting in Congo Basin Forests.

    Directory of Open Access Journals (Sweden)

    John E Fa

    Full Text Available We use data on game harvest from 60 Pygmy and non-Pygmy settlements in the Congo Basin forests to examine whether hunting patterns and prey profiles differ between the two hunter groups. For each group, we calculate hunted animal numbers and biomass available per inhabitant, P, per year (harvest rates and killed per hunter, H, per year (extraction rates. We assess the impact of hunting of both hunter groups from estimates of numbers and biomass of prey species killed per square kilometre, and by examining the proportion of hunted taxa of low, medium and high population growth rates as a measure of their vulnerability to overhunting. We then map harvested biomass (kg-1P-1Yr-1 of bushmeat by Pygmies and non-Pygmies throughout the Congo Basin. Hunting patterns differ between Pygmies and non-Pygmies; Pygmies take larger and different prey and non-Pygmies sell more for profit. We show that non-Pygmies have a potentially more severe impact on prey populations than Pygmies. This is because non-Pygmies hunt a wider range of species, and twice as many animals are taken per square kilometre. Moreover, in non-Pygmy settlements there was a larger proportion of game taken of low population growth rate. Our harvest map shows that the non-Pygmy population may be responsible for 27 times more animals harvested than the Pygmy population. Such differences indicate that the intense competition that may arise from the more widespread commercial hunting by non-Pygmies is a far more important constraint and source of conflict than are protected areas.

    Primates are regularly hunted for bushmeat in tropical forests, and systematic ecological monitoring can help determine the effect hunting has on these and other hunted species. Monitoring can also be used to inform law enforcement and managers of where hunting is concentrated. We evaluated the effects of law enforcement informed by monitoring data on density and spatial distribution of 8 monkey species in Taï National Park, Côte d'Ivoire. We conducted intensive surveys of monkeys and looked for signs of human activity throughout the park. We also gathered information on the activities of law-enforcement personnel related to hunting and evaluated the relative effects of hunting, forest cover and proximity to rivers, and conservation effort on primate distribution and density. The effects of hunting on monkeys varied among species. Red colobus monkeys (Procolobus badius) were most affected and Campbell's monkeys (Cercopithecus campbelli) were least affected by hunting. Density of monkeys irrespective of species was up to 100 times higher near a research station and tourism site in the southwestern section of the park, where there is little hunting, than in the southeastern part of the park. The results of our monitoring guided law-enforcement patrols toward zones with the most hunting activity. Such systematic coordination of ecological monitoring and law enforcement may be applicable at other sites. ©2012 Society for Conservation Biology.

We give the general result for a Nash equilibrium and payoff relations for a game based on non-factorizable joint probabilities, which embeds the classical game. We study a quantum version of Prisoners' Dilemma, Stag Hunt, and the Chicken game constructed from a given table of non-factorizable joint probabilities to find new outcomes in these games. We show that this approach provides a general framework for both classical and quantum games without recourse to the formalism of quantum mechanics.

    Tanzania holds most of the remaining large populations of African lions (Panthera leo) and has extensive areas of leopard habitat (Panthera pardus), and both species are subjected to sizable harvests by sport hunters. As a first step toward establishing sustainable management strategies, we analyzed harvest trends for lions and leopards across Tanzania's 300,000 km(2) of hunting blocks. We summarize lion population trends in protected areas where lion abundance has been directly measured and data on the frequency of lion attacks on humans in high-conflict agricultural areas. We place these findings in context of the rapidly growing human population in rural Tanzania and the concomitant effects of habitat loss, human-wildlife conflict, and cultural practices. Lion harvests declined by 50% across Tanzania between 1996 and 2008, and hunting areas with the highest initial harvests suffered the steepest declines. Although each part of the country is subject to some form of anthropogenic impact from local people, the intensity of trophy hunting was the only significant factor in a statistical analysis of lion harvest trends. Although leopard harvests were more stable, regions outside the Selous Game Reserve with the highest initial leopard harvests again showed the steepest declines. Our quantitative analyses suggest that annual hunting quotas be limited to 0.5 lions and 1.0 leopard/1000 km(2) of hunting area, except hunting blocks in the Selous Game Reserve, where harvests should be limited to 1.0 lion and 3.0 leopards/1000 km(2) . ©2010 Society for Conservation Biology.

    2010-03-23

    Evolutionary game dynamics of two players with two strategies has been studied in great detail. These games have been used to model many biologically relevant scenarios, ranging from social dilemmas in mammals to microbial diversity. Some of these games may, in fact, take place between a number of individuals and not just between two. Here we address one-shot games with multiple players. As long as we have only two strategies, many results from two-player games can be generalized to multiple players. For games with multiple players and more than two strategies, we show that statements derived for pairwise interactions no longer hold. For two-player games with any number of strategies there can be at most one isolated internal equilibrium. For any number of players with any number of strategies , there can be at most isolated internal equilibria. Multiplayer games show a great dynamical complexity that cannot be captured based on pairwise interactions. Our results hold for any game and can easily be applied to specific cases, such as public goods games or multiplayer stag hunts.

  18. From Subsistence to Commercial Hunting: Technical Shift in Cynegetic Practices Among Southern Cameroon Forest Dwellers During the 20th Century

    Directory of Open Access Journals (Sweden)

    Edmond Dounias

    2016-03-01

    Full Text Available Tropical rainforest dwellers, who are currently engaged in bushmeat trade, used to track game for their own subsistence. We investigate the technical evolution over the past century of bushmeat procurement by the Fang, a group of southern Cameroon forest dwellers who are renowned for their extensive cynegetic expertise. This investigation consists of a diachronic approach to assess Fang hunting and trapping technology by comparing firsthand data on bushmeat procurement collected in the early 1990s with detailed descriptions recorded in the early 1900s among the same populations by the German anthropologist Günter Tessmann. Other archive sources bequeathed by explorers in the twilight of the 19th century are also exploited. The comparison conveys a more dynamic view of hunting practices following the greater involvement of the Fang hunters in the bushmeat trade. Historical sources remind us that projectile weapons were initially destined for warfare and that trapping, mobilizing a vast panel of modalities, was the prominent means to catch game for domestic consumption. Net hunting and crossbow hunting, which used to be typical Fang activities, are now exclusively conducted by Pygmies; spear hunting with hounds has become anecdotal. If a large range of trap mechanisms is still functional, effort is now focused on snares, elicited by the banalization of twisted wire cable. The legacy of other remaining models is left to children who carry out a didactic form of garden trapping. The major detrimental change is the use of firearms, which were initially adopted as a warfare prestige attribute before becoming the backbone instrument of bushmeat depletion. Revisiting the past provides useful lessons for improving current hunting management, through the promotion of garden hunting and wildlife farming, and the revitalization of a collective and cultural art of hunting as an alternative to indiscriminate overhunting by neophyte and increasingly

    Conservation organizations have increasingly raised concerns about escalating rates of illegal hunting and trade in wildlife. Previous studies have concluded that people hunt illegally because they are financially poor or lack alternative livelihood strategies. However, there has been little attempt to develop a richer understanding of the motivations behind contemporary illegal wildlife hunting. As a first step, we reviewed the academic and policy literatures on poaching and illegal wildlife use and considered the meanings of poverty and the relative importance of structure and individual agency. We placed motivations for illegal wildlife hunting within the context of the complex history of how wildlife laws were initially designed and enforced to indicate how hunting practices by specific communities were criminalized. We also considered the nature of poverty and the reasons for economic deprivation in particular communities to indicate how particular understandings of poverty as material deprivation ultimately shape approaches to illegal wildlife hunting. We found there is a need for a much better understanding of what poverty is and what motivates people to hunt illegally. © 2015 Society for Conservation Biology.

  20. DAMAGE BY GAME ANIMALS IN AGRICULTURAL CROPS

    Directory of Open Access Journals (Sweden)

    Monika Sporek

    2014-06-01

    Full Text Available In the recent years the damage caused by the game animals to the agricultural crops has increased considerably. An immediate cause of this situation is an expanding population of big game, especially wild boar. This increase is primarily due to the changes in agrocenoses, dominated by large area maize cropping. The crop damage is compensated by hunting associations leasing the specific areas. The aim of this paper was to present the costs of the compensation incurred by the lease-holders of the hunting grounds. A cause - effect relationship between greater game damage and increased harvest of the game animals was demonstrated. The analysis was based on the data provided in the Statistical Yearbooks of the Central Statistical Office for 2000-2013. The study also indicated a problem of a decline in roe deer population, caused by more intense harvest resulting from farmer compensation claims.

    Nicaragua's Bosawás Biosphere Reserve is a vast forested area inhabited largely by indigenous Mayangna and Miskitu people. Most Bosawás residents rely on subsistence hunting and swidden agriculture, and hunting dogs are important for finding and securing wild game. We investigated the health of hunting dogs in three communities differing in location, size, and economy. Dogs in all communities were nutritionally compromised and experienced a heavy burden of disease. Seroprevalence of canine distemper, canine parvovirus, Rickettsia rickettsii, and Leptospira spp. exceeded 50% of dogs. At least one dog was actively shedding leptospires in urine, and many dogs were anemic and/or dehydrated. These dogs interact with wildlife in the forest and humans and domestic livestock in the communities, and may therefore serve as sources of zoonotic and wildlife diseases. Bosawás represents one of the largest intact tracts of habitat for jaguars (Panthera onca) in Central America, and given that these communities are located within the forest, jaguars may be at risk from disease spillover from hunting dogs. Dog owners reported that four of 49 dogs had been attacked and killed by jaguars in the past year, and that retaliatory killing of jaguars was sometimes practiced. Disease spillover from dogs to wildlife could occur both in the course of dogs' hunting activities as well as during jaguar attacks. A better understanding of dog depredation by jaguars, pathogen exposure in jaguars, and a management strategy for the hunting dog population, are urgently needed to mitigate these dual threats to jaguars, improve the lives of hunting dogs, and safeguard the health of their owners.

    A combination of new technologies is now leading Canada's EnCana Corporation to increase its investment in natural gas production. The corporation recently split itself into 2 companies, with Cenovus Energy taking the heavy oil assets, while the new EnCana is keeping its unconventional gas operations in northeast British Columbia (BC), Alberta, Wyoming, Colorado, Texas, and Louisiana. The division will allow EnCana to focus on becoming the best and lowest-cost producers of natural gas in North America. EnCana believes that long-term gas prices will increase over time. Four of its 8 natural gas key resources are located in Canada. The company is now producing gas from coalbed methane resources in south central Alberta, as well as from the Montney, Cadomin, and Doig geological formations. New hydraulic fracturing and horizontal drilling technologies have enabled the company to provide an estimated 100 years of gas supply in North America. EnCana has also adopted the use of various new technologies that reduce the surface disturbances and environmental impacts associated with drilling. It is hoped that EnCana's production methods will help to reduce imports of natural gas from other countries. 4 figs.

    The Hponkanrazi Wildlife Sanctuary, North Myanmar and three contiguous protected areas, comprise some of the largest expanses of natural forest remaining in the region. Demand for wildlife products has resulted in unsustainable exploitation of commercially valuable species resulting in local extirpation of vulnerable species. Camera trap, track and sign, and questionnaire-based surveys were used to examine (a) wildlife species targeted by hunters, (b) the importance of wild meat for household consumption, and (c) the significance of hunting as a livelihood activity for resident villages. Certain commercially valuable species highly preferred by hunters were either completely absent from hunt records (tiger, musk deer and otter) or infrequently obtained during actual hunts (bear, pangolin). Species obtained by hunters were commonly occurring species such as muntjacs with low commercial value and not highly preferred by hunters. Fifty eight percent of respondents ( n = 84) indicated trade, 27% listed subsistence use and 14% listed human-wildlife conflict as the main reason for hunting ( n = 84). Average amount of wild meat consumed per month is not significantly higher during the hunting season compared to the planting season (paired t-test, P > 0.05). Throughout the year, the average amount of fish consumed per month was higher than livestock or wild meat (Friedman test, P < 0.0001). Hunting is driven largely by trade and wild meat, while not a critical source of food for a large number of families could potentially be an important, indirect source of access to food for hunting families. Findings and trends from this study are potentially useful in helping design effective conservation strategies to address globally prevalent problems of declining wildlife populations and dependent human communities. The study provides recommendations to reduce illegal hunting and protect vulnerable species by strengthening park management through enforcement, increasing the

    1985-10-01

    This paper provides a model of natural resource exploration, where the sole motivation to explore arises from a strategic incentive to preempt competitors. It is assumed that private ownership rights over a finite unexplored and commonly held resource stock can be established through a costly deterministic exploration process. The open-loop and the feedback Nash equilibrium is analysed. It is shown that in between intervals of soaring exploratory activities there may be an interval where exploration is declining over time.

    Full Text Available Galați county is a geographical area that is less valued in terms of tourism, but which benefits by a natural tourism potential. The aim of this study is to identify the potential and the activities of the hunting and fishing tourism. Exploitation of hunting and fishing activities in touristic aim is only partial because of the lack of touristic infrastructure and the lack of collaboration with various travel agencies from this branch of tourism. Proposals that would help the future development and improvement of tourism activity are from “wildlife watching tourism” domain: capturing images with the camera, observing the behavior of hunting species without affecting them, providing information for those interested in the hunting behavior and life fauna, creating a wildlife museum and last but not least, upgrading the transport infrastructure.

    This study evaluates the channels through which shale formations and new natural gas supplies can change energy, economic and environmental opportunities within North America. It concludes that continued shale gas development within North America is likely to have more sweeping impacts on future energy prices than on the economy or the environment. This evaluation was conducted by a working group of 50 experts and advisors from a range of diverse universities, research institutes, corporations and government agencies. Support for the study’s conclusions came from 14 different expert teams using their own energy-economy models.

    The game statistics for the island of Olkiluoto was updated in February 2006. The estimate of game populations in Olkiluoto was done on the basis of interviews of local hunters and available statistical materials. The collected data were compared to earlier studies of game animals done in Olkiluoto. The populations of Elk and White-tailed Deer are stable, and the population of Roe Deer is increasing significantly. The populations of small mammal predators (American Mink, Raccoon Dog, Red Fox) are very high level, despite of intensive hunting. Other game animals like waterfowls are hunted moderately and the amount of catches are small. (orig.)

    In Denmark, the right to hunt is vested with the land owner but can be transferred to others and is traded on a well-established market. The dominant form of hunting leases is time limited contract transferring the hunting rights on a piece of land to one or more persons. We analyze this market...... for hunting leases using the hedonic method on a rich set of data obtained from Danish hunters.

    Full Text Available Bushmeat hunting threatens biodiversity and increases the risk of zoonotic pathogen transmission. Nevertheless, limited information exists on patterns of contact with wildlife in communities that practice bushmeat hunting, especially with respect to social drivers of hunting behavior. We used interview responses from hunters and non-hunters in rural hunting communities in Nigeria to: 1 quantify contact rates with wildlife, 2 identify specific hunting behaviors that increase frequency of contact, 3 identify socioeconomic factors that predispose individuals to hunt, and 4 measure perceptions of risk. Participants engaged in a variety of behaviors that increased contact with wild animals, including: butchering to sell (37%, being injured (14%, using body parts for traditional medicine (19%, collecting carcasses found in forests and/or farms (18%, and keeping as pets (16%. Hunters came into contact with wildlife significantly more than non-hunters, even through non-hunting exposure pathways. Participants reported hunting rodents (95%, ungulates (93%, carnivores (93%, primates (87%, and bats (42%, among other prey. Reported hunting frequencies within taxonomic groups of prey were different for different hunting behaviors. Young age, lower education level, larger household size, having a father who hunts, and cultural group were all associated with becoming a hunter. Fifty-five percent of respondents were aware that they could contract diseases from wild animals, but only 26% of these individuals reported taking protective measures. Overall, hunters in this setting frequently contact a diversity of prey in risky ways, and the decision to become a hunter stems from family tradition, modified by economic necessity. Conservation and public health interventions in such settings may be most efficient when they capitalize on local knowledge and target root socio-economic and cultural drivers that lead to hunting behavior. Importantly, interventions that

    Understanding the physical connection, or lack thereof, between the growth of galaxies and supermassive black holes is a key challenge in extragalactic astronomy. Dynamical studies of nearby galaxies are building a census of black hole masses across a broad range of galaxy types and uncovering statistical correlations between galaxy bulge properties and black hole masses. These local correlations provide a baseline for studying galaxies and black holes at higher redshifts. Recent measurements have probed the extremes of the supermassive black hole population and introduced surprises that challenge simple models of black hole and galaxy co-evolution. Future advances in the quality and quantity of dynamical black hole mass measurements will shed light upon the growth of massive galaxies and black holes in different cosmic environments.

    Full Text Available The use of game meat as a food source is currently a growing trend in our country. These products have strong and historic ties with cultural and culinary tradition, but are also appreciated for their sensory and nutritional characteristics. A major contributor to the supply of this type of product is hunting. Practiced since the dawn of time for survival, hunting has evolved into a recreational activity with substantial commercial interests. Of particular importance in this context is hunting of large ungulates. The progressive urbanization of the population has allowed for the re-establishment of bush and wooded areas that represent the ideal habitat of species such as the wild boar, whose numbers are increasing throughout the country. It is therefore clear that implementation of safety rules regarding the hunting and consumption of game meat needs to be urgently addressed. The understanding and application of rules isn’t always easy since the health law is intertwined with that of hunting, and the decision- making power left to the different regions does not contribute to a uniform application throughout the country. The aim of this study was to examine the norms that regulate the use of large wild game meat intended for human consumption and their applicability in hunting activities. From the comparison of the data reported in the literature and our field experience the rules implementation and the problems are evaluated. Operational procedures are then proposed to simplify some of the most difficult aspects and fill in the gaps highlighted.

    Gray wolves (Canis lupus) are managed for competing uses in the Greater Yellowstone Ecosystem (GYE). Tourism benefits Yellowstone National Park (YNP) visitors while trophy hunting benefits hunters outside of the park. We investigate the policy scope of gray wolf management across jurisdictional boundaries by incorporating three foundations of the behavioral ecology of wolves: refuge-seeking behavior, optimal foraging group size and territoriality. Tradeoffs between and within consumptive and non-consumptive human benefits and wolf population fitness and life history indicators are quantified as a set of elasticities, providing clear implications to resource managers. Our approach highlights that hunting intensity affects the provision of consumptive and non-consumptive human benefits across jurisdictional boundaries and ought to be managed accordingly. We also show that population levels are an incomplete indicator of species fitness, which may depend on how hunting policies impact underlying group ecology. Our findings suggest traditional optimization approaches to wildlife management may lead to suboptimal policy recommendations when the boundaries on the natural system are oversimplified. Highlighting the human element of wildlife management, we show that understanding tourist and hunter responses to wildlife population abundances is critical to balancing provision of consumptive and non-consumptive human uses.

    Therapeutic computer games might enhance children's motivation for psychotherapy, facilitate their understanding of important therapeutic concepts, structure therapy sessions, enhance treatment of migrant children and disseminate evidence-based treatment approaches. The game Treasure Hunt was developed to support cognitive behaviour therapy with children who come into treatment for various mental health problems. To evaluate the applicability and appropriateness of the game, 124 therapists answered a questionnaire on their impression of Treasure Hunt three months after download. Of these, 42 consented to participate in the further evaluation and sent questionnaires of 218 children in whose therapy Treasure Hunt had been used. A limitation of these data is an eventual positive bias, as therapists with a positive attitude towards therapeutic computer games may have been more likely to participate. Data show that the vast majority of children were satisfied their therapist had used the game during treatment. Therapists used Treasure Hunt for a broad range of diagnoses. They judged the game as helpful in the explanation of cognitive-behavioural concepts, used it as reinforcement and reported it enhanced child motivation for psychotherapy and strengthened the therapeutic relationship with the child.

    We present a novel formulation of quantum game theory based on the Schmidt decomposition, which has the merit that the entanglement of quantum strategies is manifestly quantified. We apply this formulation to 2-player, 2-strategy symmetric games and obtain a complete set of quantum Nash equilibria. Apart from those available with the maximal entanglement, these quantum Nash equilibria are extensions of the Nash equilibria in classical game theory. The phase structure of the equilibria is determined for all values of entanglement, and thereby the possibility of resolving the dilemmas by entanglement in the game of Chicken, the Battle of the Sexes, the Prisoners' Dilemma, and the Stag Hunt, is examined. We find that entanglement transforms these dilemmas with each other but cannot resolve them, except in the Stag Hunt game where the dilemma can be alleviated to a certain degree

    Conservation of Neotropical game species must take into account the livelihood and food security needs of local human populations. Hunting management decisions should therefore rely on abundance and distribution data that are as representative as possible of true population sizes and dynamics. We simultaneously applied a commonly used encounter-based method and an infrequently used sign-based method to estimate hunted vertebrate abundance in a 48,000-km2 indigenous landscape in southern Guyana. Diurnal direct encounter data collected during three years along 216, four-kilometer -long transects consistently under-detected many diurnal and nocturnal mammal species readily detected through sign. Of 32 species analyzed, 31 were detected by both methods; however, encounters did not detect one and under-detected another 12 of the most heavily hunted species relative to sign, while sign under-detected 12 never or rarely collected species relative to encounters. The six most important game animals in the region, all ungulates, were not encountered at 11–40% of village and control sites or on 29–72% of transects where they were detected by sign. Using the sign methodology, we find that tapirs, one of the terrestrial vertebrates considered most sensitive to overexploitation, are present at many sites where they were never visually detected during distance sampling. We find that this is true for many other species as well. These high rates of under-detection suggest that behavioral changes in hunted populations may affect apparent occurrence and abundance of these populations. Accumulation curves (detection of species on transects) were much steeper for sign for 12 of 16 hunted species than for encounters, but that pattern was reversed for 12 of 16 species unhunted in our area. We conclude that collection of sign data is an efficient and effective method of monitoring hunted vertebrate populations that complements encounter and camera-trapping methods in areas impacted by

    Full Text Available Much of Mongolia’s rangelands are under state control and managed via traditional land use practices and are habitat for numerous wildlife species harvested for their meat and fur. Political and economic transformations that have been occurring since the early 1990’s continues to affect all aspects of Mongolian society. To cope during periods of economic hardship, many turned to harvesting wildlife resources for income and subsistence and this resulted in precipitous declines of some populations, marmots for example. Interviews with herding households in Mongolia’s eastern steppe region were conducted to better determine how wildlife resources (Mongolian gazelle, Siberian marmot, red foxes, corsac foxes, and gray wolf are utilized and valued by herding families. Hunting, carried out by 65% of interviewees, returned an average of $103±172 dollars per household. The number of individuals hunted of any particular species during the previous year ranged widely - 46% of households hunted an average of 8±9 Mongolian gazelles (the equivalent of a small cow, 31% hunted 5±5 corsac foxes, 29% hunted 42±47 marmots, 22% hunted 3±3 red foxes, and 17% hunted 3±2 gray wolves. Differences in mean annual income between hunting and non-hunting households were similar ($1,292±1,132 vs. $1,080±1,196 however the median difference was greater ($1,009 vs $749. However, non-hunting households owned significantly more livestock than hunting households (168±183 vs. 93±92 Livestock Units, and the proportion of hunting households living below the poverty line was higher. Households that were larger or had few numbers of livestock were more likely to engage in hunting than smaller households with more livestock. Household and livestock variables were also significant predictors of a households likelihood of hunting Mongolian gazelle, Siberian marmot, and corsac fox, but not for red fox or gray wolf. Wildlife management policies will likely receive greater

    A subject of major importance in fundamental physics is the investigation of the origin of Electroweak Symmetry Breaking. The mechanism of mass generation through the spontaneous breaking of a gauge symmetry is called the Brout-Englert-Higgs mechanism and is associated with the appearance of a physical scalar boson. The discovery announced at CERN on 4th July 2012 by the ATLAS and CMS Collaborations of a boson at a mass close to 125 GeV/c2, compatible with this scalar boson of the Standard Model, the so-called Higgs boson, mainly in γγ, ZZ and WW decay modes, with compatible evidence also found at Fermilab in the bb mode, changed the landscape.

    2009-08-11

    Zooarchaeological research at Qesem Cave, Israel demonstrates that large-game hunting was a regular practice by the late Lower Paleolithic period. The 400- to 200,000-year-old fallow deer assemblages from this cave provide early examples of prime-age-focused ungulate hunting, a human predator-prey relationship that has persisted into recent times. The meat diet at Qesem centered on large game and was supplemented with tortoises. These hominins hunted cooperatively, and consumption of the highest quality parts of large prey was delayed until the food could be moved to the cave and processed with the aid of blade cutting tools and fire. Delayed consumption of high-quality body parts implies that the meat was shared with other members of the group. The types of cut marks on upper limb bones indicate simple flesh removal activities only. The Qesem cut marks are both more abundant and more randomly oriented than those observed in Middle and Upper Paleolithic cases in the Levant, suggesting that more (skilled and unskilled) individuals were directly involved in cutting meat from the bones at Qesem Cave. Among recent humans, butchering of large animals normally involves a chain of focused tasks performed by one or just a few persons, and butchering guides many of the formalities of meat distribution and sharing that follow. The results from Qesem Cave raise new hypotheses about possible differences in the mechanics of meat sharing between the late Lower Paleolithic and Middle Paleolithic.

    Full Text Available We explore the impact of "game changers" on the dynamics of innovation over time in three problem domains, that of wilderness protection, women's rights, and assimilation of indigenous children in Canada. Taking a specifically historical and cross-scale approach, we look at one social innovation in each problem domain. We explore the origins and history of the development of the National Parks in the USA, the legalization of contraception in the USA and Canada, and the residential school system in Canada. Based on a comparison of these cases, we identify three kinds of game changers, those that catalyze social innovation, which we define as "seminal," those that disrupt the continuity of social innovation, which we label exogenous shocks, and those that provide opportunities for novel combinations and recombinations, which we label as endogamous game changers.

    The removal of individuals through hunting can destabilize social structure, potentially affecting population dynamics. Although previous studies have shown that hunting can indirectly reduce juvenile survival through increased sexually selected infanticide (SSI), very little is known about the spatiotemporal effects of male hunting on juvenile survival. Using detailed individual monitoring of a hunted population of brown bears (Ursus arctos) in Sweden (1991-2011), we assessed the spatiotemporal effect of male removal on cub survival. We modelled cub survival before, during and after the mating season. We used three proxies to evaluate spatial and temporal variation in male turnover; distance and timing of the closest male killed and number of males that died around a female's home range centre. Male removal decreased cub survival only during the mating season, as expected in seasonal breeders with SSI. Cub survival increased with distance to the closest male killed within the previous 1·5 years, and it was lower when the closest male killed was removed 1·5 instead of 0·5 year earlier. We did not detect an effect of the number of males killed. Our results support the hypothesis that social restructuring due to hunting can reduce recruitment and suggest that the distribution of the male deaths might be more important than the overall number of males that die. As the removal of individuals through hunting is typically not homogenously distributed across the landscape, spatial heterogeneity in hunting pressure may cause source-sink dynamics, with lower recruitment in areas of high human-induced mortality. © 2016 The Authors.

    Full Text Available The research described in the present article was implemented to define the locations of two World War II shipwrecks, the German raider Kormoran, and the Australian light cruiser HMAS Sydney. The paper describes the long and complex trail that led through inefficient oceanographic prediction to ambiguous historical prediction involving a single report and on to precise cognitive prediction based on nine reports from more than 70 survivors, a process that yielded a single target position or ‘mean’ just 2.7 NM (nautical miles from the wreck of Kormoran. Prediction for the position of the wreck of Sydney opened with wishful thinking that she had somehow reached the coast more than 100 NM away when cognitive analysis of the survivor’s reports actually provided the basis for accurate prediction in a position near to the wreck of Kormoran. In the account provided below, the focus on cognitive procedures emerged from, first, a review of a sample of the shipwreck hunts, and, second, growing awareness of the extraordinarily rich database available for this search, and the extent to which it was open to cognitive analysis. This review touches on both the trans-disciplinary and the cognitive or intra-disciplinary issues that so challenged the political entities responsible for supervising of the search for the wrecks of Kormoran and Sydney. One of the theoretical questions that emerged from these debate concerns the model of expertise advanced by Collins (2013. The decomposability of alleged forms of expertise is revealed as a fundamental problem for research projects that might or might not benefit from trans-disciplinary research. Where expertise can be decomposed for operational purposes, the traditional dividing lines between experts and novices, and fools for that matter, are much harder to discern, and require advanced and scientifically informed review.

    Starting from Zermelo’s classical formal treatment of chess, we trace through history the analysis of two-player win/lose/draw games with perfect information and potentially infinite play. Such chess-like games have appeared in many different research communities, and methods for solving them......, such as retrograde analysis, have been rediscovered independently. We then revisit Washburn’s deterministic graphical games (DGGs), a natural generalization of chess-like games to arbitrary zero-sum payoffs. We study the complexity of solving DGGs and obtain an almost-linear time comparison-based algorithm...

  4. Mourning dove hunting regulation strategy based on annual harvest statistics and banding data

    Although managers should strive to base game bird harvest management strategies on mechanistic population models, monitoring programs required to build and continuously update these models may not be in place. Alternatively, If estimates of total harvest and harvest rates are available, then population estimates derived from these harvest data can serve as the basis for making hunting regulation decisions based on population growth rates derived from these estimates. I present a statistically rigorous approach for regulation decision-making using a hypothesis-testing framework and an assumed framework of 3 hunting regulation alternatives. I illustrate and evaluate the technique with historical data on the mid-continent mallard (Anas platyrhynchos) population. I evaluate the statistical properties of the hypothesis-testing framework using the best available data on mourning doves (Zenaida macroura). I use these results to discuss practical implementation of the technique as an interim harvest strategy for mourning doves until reliable mechanistic population models and associated monitoring programs are developed.

    2006-01-01

    This volume lays the mathematical foundations for the theory of differential games, developing a rigorous mathematical framework with existence theorems. It begins with a precise definition of a differential game and advances to considerations of games of fixed duration, games of pursuit and evasion, the computation of saddle points, games of survival, and games with restricted phase coordinates. Final chapters cover selected topics (including capturability and games with delayed information) and N-person games.Geared toward graduate students, Differential Games will be of particular interest

  7. High risk of lead contamination for scavengers in an area with high moose hunting success.

    Top predators and scavengers are vulnerable to pollutants, particularly those accumulated along the food chain. Lead accumulation can induce severe disorders and alter survival both in mammals (including humans) and in birds. A potential source of lead poisoning in wild animals, and especially in scavengers, results from the consumption of ammunition residues in the tissues of big game killed by hunters. For two consecutive years we quantified the level lead exposure in individuals of a sentinel scavenger species, the common raven (Corvus corax), captured during the moose (Alces alces) hunting season in eastern Quebec, Canada. The source of the lead contamination was also determined using stable isotope analyses. Finally, we identified the different scavenger species that could potentially be exposed to lead by installing automatic cameras targeting moose gut piles. Blood lead concentration in ravens increased over time, indicating lead accumulation over the moose-hunting season. Using a contamination threshold of 100 µg x L(-1), more than 50% of individuals were lead-contaminated during the moose hunting period. Lead concentration was twice as high in one year compared to the other, matching the number of rifle-shot moose in the area. Non-contaminated birds exhibited no ammunition isotope signatures. The isotope signature of the lead detected in contaminated ravens tended towards the signature from lead ammunition. We also found that black bears (Ursus americanus), golden eagles and bald eagles (Aquila chrysaetos and Haliaeetus leucocephalus, two species of conservation concern) scavenged heavily on moose viscera left by hunters. Our unequivocal results agree with other studies and further motivate the use of non-toxic ammunition for big game hunting.

    Full Text Available Aim. The goal of the research is that: to identify the taxonomic composition of game species and make full list of species to assess the current state of populations and resources to carry out eco-faunistic analysis of the distribution of game mammals habiting Shelkovskiy district of Chechnya. Methods. We used mapping techniques, various methods of census forms and scientific processing of the collected material, systematic and bioecological analysis. Results. As a result, we have identified 5 ecological complexes and characterized them by distribution on the identified and described natural habitats. We have made an inventory of species, identified conditions of rare species and determined their status. Biometric data has been obtained for a number of species; their biological and ecological features have been described. We also identified the species composition of game mammals and their spatial distribution of habitats. The differentiation of species in ecological groups has been carried out. Data has been obtained on the number of nine major types for the period of 2012-2013, and their characteristics. We have made an estimation of ecological and economic potential of resources of game mammals of the study area. Conclusions. Based on the analysis of the results we can make a judgment about the level of biodiversity of species of game mammals of the studied area, the current state of their number and possible use for commercial, sports and recreational purposes. We propose specific measures such as the use of existing biological resources i.e. species of mammals, as well as the creation of new protected areas as a form of preserving and increasing the number of mammals in the area. The research results can be useful for monitoring and creating specially protected natural reservations, protection of endangered species. The findings have implications for the organization of hunting economy to increase the number of game animals.

    Ramsay Hunt syndrome, first described by J. Ramsay Hunt in 1907, encompassed the symptoms of otalgia, erythematous vesicular rash on the auricle, and facial paralysis. Although rare, in some cases, the varicella zoster virus responsible for the illness can also be associated with involvement of cranial nerves III-XII, cervical nerves, aseptic meningitis, and the syndrome of inappropriate secretion of antidiuretic hormone. We present a case of a patient with clinical evidence of Ramsay Hunt syndrome involving the cranial nerves V, VII, VIII, X, and, possibly, XII. Pharyngeal wall and vocal fold paralysis, and severely reduced laryngeal elevation, resulted in such significant dysphagia that percutaneous endoscopic gastrostomy tube placement was required.

    2016-01-01

    The current view for the southern Levant is that wild game hunting was replaced by herd management over the course of the Pre-Pottery Neolithic B period, but there is significant debate over the timing, scale and origin of this transition. To date, most relevant studies focus either on wild game exploitation in the periods prior to domestication or on classic markers of domestication of domestic progenitor species over the course of the PPNB. We studied the faunal remains from the 2007-2008 excavations of the Middle PPNB (MPPNB) site of Yiftah'el, Northern Israel. Our analysis included a close examination of the timing and impact of the trade-off between wild game and domestic progenitor taxa that reflects the very beginning of this critical transition in the Mediterranean zone of the southern Levant. Our results reveal a direct trade-off between the intensive hunting of wild ungulates that had been staples for millennia, and domestic progenitor taxa. We suggest that the changes in wild animal use are linked to a region-wide shift in the relationship between humans and domestic progenitor species including goat, pig and cattle.

  14. Predator facilitation or interference: a game of vipers and owls.

    2014-04-01

    In predator-prey foraging games, the prey's reaction to one type of predator may either facilitate or hinder the success of another predator. We ask, do different predator species affect each other's patch selection? If the predators facilitate each other, they should prefer to hunt in the same patch; if they interfere, they should prefer to hunt alone. We performed an experiment in a large outdoor vivarium where we presented barn owls (Tyto alba) with a choice of hunting greater Egyptian gerbils (Gerbillus pyramidum) in patches with or without Saharan horned vipers (Cerastes cerastes). Gerbils foraged on feeding trays set under bushes or in the open. We monitored owl location, activity, and hunting attempts, viper activity and ambush site location, and the foraging behavior of the gerbils in bush and open microhabitats. Owls directed more attacks towards patches with vipers, and vipers were more active in the presence of owls. Owls and vipers facilitated each other's hunting through their combined effect on gerbil behavior, especially on full moon nights when vipers are more active. Owls forced gerbils into the bushes where vipers preferred to ambush, while viper presence chased gerbils into the open where they were exposed to owls. Owls and vipers took advantage of their indirect positive effect on each other. In the foraging game context, they improve each other's patch quality and hunting success.

    Hunting cheetah reportedly store metabolic heat during the chase and abandon chases because they overheat. Using biologging to remotely measure the body temperature (every minute) and locomotor activity (every 5 min) of four free-living cheetah, hunting spontaneously, we found that cheetah abandoned hunts, but not because they overheated. Body temperature averaged 38.4°C when the chase was terminated. Storage of metabolic heat did not compromise hunts. The increase in body temperature following a successful hunt was double that of an unsuccessful hunt (1.3°C ± 0.2°C versus 0.5°C ± 0.1°C), even though the level of activity during the hunts was similar. We propose that the increase in body temperature following a successful hunt is a stress hyperthermia, rather than an exercise-induced hyperthermia. PMID:23883578

    We consider a hunting area and a wildlife reserve and answer the question: How does clever migration decision affect the social optimal and the private optimal hunting levels and population stocks? We analyze this in a model allowing for two-way migration between hunting and reserve areas, where...... the populations’ migration decisions depend on both hunting pressure and relative population densities. In the social optimum a pure stress effect on the behavior of smart wildlife exists. This implies that the population level in the wildlife reserve tends to increase and the population level in the hunting area...... and hunting levels tend to decrease. On the other hand, the effect on stock tends to reduce the population in the wildlife reserve and increase the population in the hunting area and thereby also increase hunting. In the case of the private optimum, open-access is assumed and we find that the same qualitative...

    The pollution of wetlands by lead derived from waterfowl hunting with lead shot was investigated. We determined soil pellet density and Pb concentration in soil, water and vegetation in natural wetlands and rice fields in central-eastern Santa Fe province, Argentina. Pellet density varied greatly among hunting sites (between 5.5-141 pellets/m(2)) and pellets were present in some control sites. Soil Pb concentration in most hunting sites (approximately 10-20 mg kg(-1)) was not much higher than in control sites (~5-10 mg kg(-1)), with the exception of the site with highest pellet density, which also had a high Pb soil concentration. In water, on the other hand, Pb concentration was similar in all sites (~4-7 μg L(-1)), both control and hunting, and higher than reference values for aquatic media. Lead was also present in vegetation, including grasses and rice crops, in almost all cases. Most soil-collection sites were slightly acidic, and were frequently flooded. These results strongly suggest that metallic Pb from spent shot is oxidized and dissolved due to wetland conditions. Thus, the pollutant is readily mobilized and distributed across all wetland areas, effectively homogenizing its concentration in locations with and without hunting activities. The replacement of lead by nontoxic materials in pellets appears to be the only effective way to prevent Pb pollution in wetlands. Copyright © 2015 Elsevier B.V. All rights reserved.

    The risk for humans to contract bovine tuberculosis through the consumption of undercooked game meat as well as biltong (traditionally dried game meat) is a concern. The survival potential of Mycobacterium bovis during the cooking and drying processes was researched in a preceding study on beef and the positive results compelled the authors to investigate the results with a similar preliminary study on game meat. Muscular, lymphatic and visceral tissues from skin test positive African buffalo (Syncerus caffer) and greater kudu (Tragelaphus strepsiceros) with tuberculous lesions were collected from the Hluhluwe iMfolozi Park during the park's culling programme. The different tissues were exposed to cooking and the muscular tissue to the drying process prior to culture. All acid-fast isolates were analysed by polymerase chain reaction for the presence of Mycobacterium bovis. All tissues were found negative for Mycobacterium bovis but non-tuberculous mycobacteria were isolated from kidney, liver, heart and lymph nodes. The results showed that these processes will kill Mycobacterium bovis but the unexpected recovery of non-tuberculous mycobacteria suggests possible survival and resistance characteristics of these strains which might be of veterinary public health interest.

    The game statistics for the island of Olkiluoto were updated in the summer 2014 and compared with earlier statistics. In addition, the estimated biomass of hunted animals was calculated. The reported game bag and population size estimates are based on the annual action report of local hunting club (Olkiluodon Metsaestysseura ry) and interviews of hunting club's secretary. No moose or deer inventories were made in the winter 2013-2014. The moose population has been a slightly increasing when comparing the previous year; there were 4-6 individuals on the island after hunting season. The number of moose varies because they tend to move between the island and mainland. Winter 2013-2014 was relatively easy for white-tailed deer and roe deer but the predation caused by lynxes inhibits the increase of populations. However, the current amount of lynxes on the island is unknown because the lack of snow in the winter 2013-2014. In the summer of 2014, there were several lynx observations. The number of hunted raccoon dogs was almost four times as large as in the previous year; altogether 26 individuals were killed. There were no noticeable changes in the number of other hunted small or medium-sized predators. American minks were not killed at all. The total number of hunted hares decreased from eleven to seven. Once again, mallard was the most common hunted bird species followed by hooded crow. Other bird species hunted were wood pigeon, herring gull, hazel grouse, wigeon, teal and common pochard. The total biomass hunted was approximately 1 225 kilos (1 170 for mammals and 55 for birds) which was 305 kilos more than in the previous year. The biomass destined to human consumption (i.e. game meat) was approximately 415 kilos (400 kilos for mammals, 15 for birds). (orig.)

However, the current amount of lynxes on the island is unknown because the lack of snow in the winter 2013-2014. In the summer of 2014, there were several lynx observations. The number of hunted raccoon dogs was almost four times as large as in the previous year; altogether 26 individuals were killed. There were no noticeable changes in the number of other hunted small or medium-sized predators. American minks were not killed at all. The total number of hunted hares decreased from eleven to seven. Once again, mallard was the most common hunted bird species followed by hooded crow. Other bird species hunted were wood pigeon, herring gull, hazel grouse, wigeon, teal and common pochard. The total biomass hunted was approximately 1 225 kilos (1 170 for mammals and 55 for birds) which was 305 kilos more than in the previous year. The biomass destined to human consumption (i.e. game meat) was approximately 415 kilos (400 kilos for mammals, 15 for birds). (orig.)

    In recent years, astronomers have developed many wide-field imaging surveys in which the same targets are observed again and again. This new form of observing has allowed us to discover optical and radio transients explosive or irregular events with durations ranging from seconds to years. The dynamic infrared sky, however, has remained largely unexplored until now.Infrared ExplorationExample of a transient: SPIRITS 14ajc was visible when imaged by SPIRITS in 2014 (left) but it wasnt there during previous imaging between 2004 and 2008 (right). The bottom frame shows the difference between the two images. [Adapted from Kasliwal et al. 2017]Why hunt for infrared transients? Optical wavelengths dont allow us to observe events that are obscured, such that their own structure or their surroundings hide them from our view. Both supernovae and luminous red novae (associated with stellar mergers) are discoverable as infrared transients, and there may well be new types of transients in infrared that we havent seen before!To explore this uncharted territory, a team of scientists developed SPIRITS, the Spitzer Infrared Intensive Transients Survey. Begun in 2014, SPIRITS is a five-year long survey that uses the Spitzer Space Telescope to conduct a systematic search for mid-infrared transients in nearby galaxies.In a recent publication led by Mansi Kasliwal (Caltech and the Carnegie Institution for Science), the SPIRITS team has now detailed how their survey works and what theyve discovered in its first year.The light curves of SPRITEs (red stars) lie in the mid-infared luminosity gap between novae (orange) and supernovae (blue). [Kasliwal et al. 2017]Mystery TransientsKasliwal and collaborators used Spitzer to monitor 190 nearby galaxies. In SPIRITS first year, they found over 1958 variable stars and 43 infrared transient sources. Of these 43 transients, 21 were known supernovae, 4 were in the luminosity range of novae, and 4 had optical counterparts. The remaining 14 events

    2014-01-01

    Conservation scientists are increasingly focusing on the drivers of human behavior and on the implications of various sources of uncertainty for management decision making. Trophy hunting has been suggested as a conservation tool because it gives economic value to wildlife, but recent examples show that overharvesting is a substantial problem and that data limitations are rife. We use a case study of trophy hunting of an endangered antelope, the mountain nyala (Tragelaphus buxtoni), to explore how uncertainties generated by population monitoring and poaching interact with decision making by 2 key stakeholders: the safari companies and the government. We built a management strategy evaluation model that encompasses the population dynamics of mountain nyala, a monitoring model, and a company decision making model. We investigated scenarios of investment into antipoaching and monitoring by governments and safari companies. Harvest strategy was robust to the uncertainty in the population estimates obtained from monitoring, but poaching had a much stronger effect on quota and sustainability. Hence, reducing poaching is in the interests of companies wishing to increase the profitability of their enterprises, for example by engaging community members as game scouts. There is a threshold level of uncertainty in the population estimates beyond which the year-to-year variation in the trophy quota prevented planning by the safari companies. This suggests a role for government in ensuring that a baseline level of population monitoring is carried out such that this level is not exceeded. Our results illustrate the importance of considering the incentives of multiple stakeholders when designing frameworks for resource use and when designing management frameworks to address the particular sources of uncertainty that affect system sustainability most heavily.

    Brezinka, Veronika

    2016-01-01

    A literature survey on new developments in the area of video games and psychotherapy of children and adolescents was conducted. Despite the omnipresence of computers and the internet, development of therapeutic games seems rather slow. The video game Treasure Hunt was introduced in 2008 to support treatment of children with internalizing and externalizing disorders. Camp Cope-A-Lot was developed for treatment of anxious children, whereas the self-help game SPARX is directed at depressed adolescents. Rage-Control is a biofeedback game for children with anger problems. The game Zoo U aims to assess and train social skills of primary school children. Ricky and the Spider for young children with obsessive compulsive disorder is meant to support the cognitive-behavioural treatment of these patients. Clash- Back is a French game for adolescents with externalizing problems. Possible reasons for the relatively slow development of therapeutic games are the high methodological demands concerning an evaluation as well as the high costs of game development. Nonetheless, computers and the internet are bound to influence psychotherapy with children and adolescents in the long run.

    When the incidence and prevalence of most common vaccine preventable childhood infectious diseases are constantly low, as is the case in many industrialized countries, the incidence of vaccine-associated side effects might become a key determinant in vaccine demand. We study an SIR transmission model with dynamic vaccine demand based on an imitation mechanism where the perceived risk of vaccination is modelled as a function of the incidence of vaccine side effects. The model shows some important differences compared to previous game dynamic models of vaccination, and allows noteworthy inferences as regards both the past and future lifetime of vaccination programmes. In particular it is suggested that a huge disproportion between the perceived risk of disease and vaccination is necessary in order to achieve high coverages. This disproportion is further increased in highly industrialised countries. Such considerations represent serious challenges for future vaccination programmes. Copyright © 2010 Elsevier Ltd.

    To compare upper limb kinematics of children with spastic cerebral palsy (CP) using a passive rehabilitation joystick with those of adults and able-bodied children, to better understand the design requirements of computer-based rehabilitation devices. A blocked comparative study involving seven children with spastic CP, nine able-bodied adults and nine able-bodied children, using a joystick system to play a computer game whilst the kinematics of their upper limb were recorded. The translational kinematics of the joystick's end point and the participant's shoulder movement (protraction/retraction) and elbow rotational kinematics (flexion/extension) were analysed for each group. Children with spastic CP matched their able-bodied peers in the time taken to complete the computer task, but this was due to a failure to adhere to the task instructions of travelling along a prescribed straight line when moving between targets. The spastic CP group took longer to initiate the first movement, which showed jerkier trajectories and demonstrated qualitatively different movement patterns when using the joystick, with shoulder movements that were significantly of greater magnitude than the able-bodied participants. Children with spastic CP generate large shoulder and hence trunk movements when using a joystick to undertake computer-generated arm exercises. This finding has implications for the development and use of assistive technologies to encourage exercise and the instructions given to users of such systems. A kinematic analysis of upper limb function of children with CP when using joystick devices is presented. Children with CP may use upper body movements to compensate for limitations in voluntary shoulder and elbow movements when undertaking computer games designed to encourage the practice of arm movement. The design of rehabilitative computer exercise systems should consider movement of the torso/shoulder as it may have implications for the quality of therapy in the

  11. Average-energy games

    2015-09-01

    Full Text Available Two-player quantitative zero-sum games provide a natural framework to synthesize controllers with performance guarantees for reactive systems within an uncontrollable environment. Classical settings include mean-payoff games, where the objective is to optimize the long-run average gain per action, and energy games, where the system has to avoid running out of energy. We study average-energy games, where the goal is to optimize the long-run average of the accumulated energy. We show that this objective arises naturally in several applications, and that it yields interesting connections with previous concepts in the literature. We prove that deciding the winner in such games is in NP inter coNP and at least as hard as solving mean-payoff games, and we establish that memoryless strategies suffice to win. We also consider the case where the system has to minimize the average-energy while maintaining the accumulated energy within predefined bounds at all times: this corresponds to operating with a finite-capacity storage for energy. We give results for one-player and two-player games, and establish complexity bounds and memory requirements.

  12. Identity-driven differences in stakeholder concerns about hunting wolves.

    Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT) has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet) with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666) cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

  17. Stress Induces Contextual Blindness in Lotteries and Coordination Games

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available In this paper, we study how stress affects risk taking in three tasks: individual lotteries, Stag Hunt (coordination games, and Hawk-Dove (anti-coordination games. Both control and stressed subjects take more risks in all three tasks when the value of the safe option is decreased and in lotteries when the expected gain is increased. Also, subjects take longer to take decisions when stakes are high, when the safe option is less attractive and in the conceptually more difficult Hawk-Dove game. Stress (weakly increases reaction times in those cases. Finally, our main result is that the behavior of stressed subjects in lotteries, Stag Hunt and Hawk-Dove are all highly predictive of each other (p-value < 0.001 for all three pairwise correlations. Such strong relationship is not present in our control group. Our results illustrate a “contextual blindness” caused by stress. The mathematical and behavioral tensions of Stag Hunt and Hawk-Dove games are axiomatically different, and we should expect different behavior across these games, and also with respect to the individual task. A possible explanation for the highly significant connection across tasks in the stress condition is that stressed subjects habitually rely on one mechanism to make a decision in all contexts whereas unstressed subjects utilize a more cognitively flexible approach.

    In addition to the process of photosynthesis, the bee community is the main source of energy in food production, honey-plants used by game and people in the hunting grounds ecosystem. It is a well-known fact that thousands of plant species depend on the presence of bee communities (pollination, fertilization). In this paper we studied the presence of the bee community in the hunting grounds of Croatian Forests, and their influence on the number of game (wild pigs), as well as the quality of honey, honey plants in the hunting grounds used by people and game. We established the total number of game (wild boars). The honey quality parameters were determined using the Harmonised methods of the European Honey (Bogdanov et al., 1997) and the pollen analysis by were conducted according to Harmonised methods of melissopalynology (Von der Ohe et al., 2004). Research results indicate that the presence of the bee community influences the number of wild boars from 3-18%, and the quality of honey is in line with the European and world standards. The SAS/STAT package was used for the statistical analysis (SAS Institute Inc., 2000). The significance of the differences among the groups was determined by Duncan test.

    The authors report the case of a 21-year-old man who was killed while duck hunting when a shotgun accidentally discharged, shooting him in the head. The loaded weapon, which had been lying on the ground with the safety off and the muzzle pointed toward a river a few feet away, discharged when a hunting dog stepped on the trigger. Scene investigation confirmed that the victim had been standing in the river, planting decoys, with his head approximately level with the adjacent bank. Autopsy examination and ballistic testing confirmed a range of fire consistent with the witness' statements. Examination of the weapon in question documented a light trigger pull but no mechanical defects. The authors review the epidemiology and causality of hunting accidents and discuss the various safety rules that were violated in this highly unusual case. The importance of a complete death investigation, including autopsy, when dealing with a firearm death is emphasized.

  1. Adhesive foot pads: an adaptation to climbing? An ecological survey in hunting spiders.

    Science.gov (United States)

    Wolff, Jonas O; Gorb, Stanislav N

    2015-02-01

    Hairy pads relying on dry adhesion are fascinating structures that convergently evolved among spiders and lizards. Numerous studies underline the functional aspects leading to their strong adhesion to smooth surfaces, but rarely has their role been studied in the context of natural habitats and surfaces that animals are faced with. In hunting spiders, the hairy foot pads (claw tufts) underneath the paired claws are assumed to be an adaptation to a climbing lifestyle, particularly on smooth plant surfaces. However, surfaces that are too smooth for claws to generate a sufficient grip are rather rare in natural habitats and above-ground habitats are occupied by hunting spiders both with and without claw tufts. In this study we estimated the proportion of claw tuft-bearing hunting spiders (ct+ ratio) among microhabitat-specific assemblages by conducting both a field study and a meta-analysis approach. The effect of surface characteristics, structure fragmentation and altitude of the microhabitat niche on the ct+ ratio was analyzed. We hypothesized that the ct+ ratio will be higher in (i) hunting spider assemblages obtained from microhabitats above the ground than from those at the ground and (ii) in hunting spider assemblages obtained from microhabitats with smoother surfaces (tree foliage) than those with rougher surfaces (barks, stones), and lower in (iii) hunting spider assemblages obtained from microhabitats with more fragmented structures (small leaves) than in those with comparable but less fragmented structures (large leaves). We found the ct+ ratio to be significantly affected by the microhabitat's distance from the ground, whereas surface characteristics and fragmentation of the substrates were of minor importance. This suggests that claw tufts are highly beneficial when the microhabitat's height exceeds a value where the additional pad-related costs are exceeded by the costs of dropping. We assume the benefit to be mainly due to gaining a high safety factor

    .Observatories on the HuntNeutrino observatories are often built to take advantage of pre-existing deep bodies of ice or water for their detectors. One of the most well-known neutrino observatories is IceCube, an array of detectors located far beneath the Antarctic ice. A few years ago, IceCube announced the observation of an excess of events over the expected atmospheric background the first detection of a diffuse flux of cosmic neutrinos. The next step:confirmation from another observatory.ANTARES detections across different energy bins, for both track-like (top) and shower-like (bottom) events. Plot includes data (black), model for atmospheric events (blue), and two different models for cosmic events (red). Above an energy cutoff of 20 TeV (grey line), nine excess neutrinos are detected relative to the atmospheric model. [Albert et al. 2018]Enter ANTARES, short for Astronomy with a Neutrino Telescope and Abyss Environmental Research. Completed in 2008, this neutrino telescope was built 1.5 miles beneath the surface of the Mediterranean Sea. Now the collaboration is presenting the results of their nine-year search for a diffuse cosmic neutrino flux.A Mild ExcessThe outcome? Success! sort of.The very nature of neutrinos elusiveness means that we have to draw conclusions with very small numbers of detections. Over nine years, ANTARES detected a total of 33 events above an energy cutoff of 20 TeV, whereas models predict it should have seen only 24 such events due to atmospheric particles. This detection of nine extra neutrinos may sound insubstantial but statistically, it allows the team to reject the hypothesis that there is no diffuse cosmic flux at an 85% confidence level.The mild excess of neutrinos detected by ANTARES is by no means a smoking gun, but the properties of this cosmic neutrino flux are consistent with those detected by IceCube, which is a very promising outcome. At the moment, it would seem that a diffuse flux of cosmic neutrinos is present and the next generation

    The purpose of this article is to analyze the South Korea and China of computer game research, and the current state of research in Japan. Excessive game actions were analyzed by PET-MRI, MRI, fMRI, NIRS, EEG. These results showed that the prefrontal cortical activity decreased during game play. Also, game addiction causes damage to the prefrontal cortex. The NIRS-EEG and simultaneous recording, during game play correspond well with the decrease of β band and oxygen-hemoglobin. The α band did not change with game play. However, oxygen-hemoglobin decreased during game play. South Korea, game addiction measures have been analyzed since 2002, but in Japan the research is recent.

    Full Text Available The Yul shul (Yushu ngas bzang Tribe historically possessed a rich hunting tradition. Wildlife was hunted for food and other animal products. By 2007, hunting culture had diminished due to improvements in living conditions, wildlife protection laws, greater state control of wildlife product skin market and gun ownership, animal diseases, and the absence of such wildlife as wild yaks in local areas.

  7. Asymmetric Evolutionary Games

    Science.gov (United States)

    McAvoy, Alex; Hauert, Christoph

    2015-01-01

    Evolutionary game theory is a powerful framework for studying evolution in populations of interacting individuals. A common assumption in evolutionary game theory is that interactions are symmetric, which means that the players are distinguished by only their strategies. In nature, however, the microscopic interactions between players are nearly always asymmetric due to environmental effects, differing baseline characteristics, and other possible sources of heterogeneity. To model these phenomena, we introduce into evolutionary game theory two broad classes of asymmetric interactions: ecological and genotypic. Ecological asymmetry results from variation in the environments of the players, while genotypic asymmetry is a consequence of the players having differing baseline genotypes. We develop a theory of these forms of asymmetry for games in structured populations and use the classical social dilemmas, the Prisoner’s Dilemma and the Snowdrift Game, for illustrations. Interestingly, asymmetric games reveal essential differences between models of genetic evolution based on reproduction and models of cultural evolution based on imitation that are not apparent in symmetric games.

    The aim of this paper is to discuss the significance of hunting in "The Bear" and "Delta Autumn", the fifth and sixth stories in William Faulkner‟s Go Down, Moses (1942). In this paper, I would like to show that hunting plays an important role in Faulkner's Southern society, referring to the studies of Maria Mies, a German sociologist. In her view, hunting is useful to a patriarchal society, which strictly distinguishes men from women. As a part of a social system, hunting succeeds in g...

  9. A decision rule based on goal programming and one-stage models for uncertain multi-criteria mixed decision making and games against nature

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available This paper is concerned with games against nature and multi-criteria decision making under uncertainty along with scenario planning. We focus on decision problems where a deterministic evaluation of criteria is not possible. The procedure we propose is based on weighted goal programming and may be applied when seeking a mixed strategy. A mixed strategy allows the decision maker to select and perform a weighted combination of several accessible alternatives. The new method takes into consideration the decision maker’s preference structure (importance of particular goals and nature (pessimistic, moderate or optimistic attitude towards a given problem. It is designed for one-shot decisions made under uncertainty with unknown probabilities (frequencies, i.e. for decision making under complete uncertainty or decision making under strategic uncertainty. The procedure refers to one-stage models, i.e. models considering combinations of scenarios and criteria (scenario-criterion pairs as distinct meta-attributes, which means that the novel approach can be used in the case of totally independent payoff matrices for particular targets. The algorithm does not require any information about frequencies, which is especially desirable for new decision problems. It can be successfully applied by passive decision makers, as only criteria weights and the coefficient of optimism have to be declared.

Coupling spatial configuration with performance theory of rituals as liminal phenomena, I put forward a model and a new understanding of the magic circle......When we play games of any kind, from tennis to board games, it is easy to notice that games seem to be configured in space, often using stripes or a kind of map on a board. Some games are clearly performed within this marked border, while it may be difficult to pinpoint such a border in games like...... hide-and-seek, but even these games are still spatially configured. The border (visible or not) both seem to separate and uphold the game that it is meant for. This chapter sets out to analyse the possible border that separates a game from the surrounding world.

    Abstract Paca (Cuniculus paca Linnaeus, 1766) is the second largest rodent found in Brazil. The quality of the meat and a long tradition of hunting have contributed to the decline of the natural populations of this species. Hunting of paca is strictly prohibited in Brazil, but in spite of this restriction, no forensic tools are available for the identification of the meat. We describe an efficient method, based on single nucleotide polymorphisms of the cytochrome b gene, that can be used to d...

  12. Supporting online learning with games

    Yao, JingTao; Kim, DongWon; Herbert, Joseph P.

    2007-04-01

    This paper presents a study on Web-based learning support systems that is enhanced with two major subsystems: a Web-based learning game and a learning-oriented Web search. The Internet and theWeb may be considered as a first resource for students seeking for information and help. However, much of the information available online is not related to the course contents or is wrong in the worse case. The search subsystem aims to provide students with precise, relative and adaptable documents about certain courses or classes. Therefore, students do not have to spend time to verify the relationship of documents to the class. The learning game subsystem stimulates students to study, enables students to review their studies and to perform self-evaluation through a Web-based learning game such as a treasure hunt game. During the challenge and entertaining learning and evaluation process, it is hoped that students will eventually understand and master the course concepts easily. The goal of developing such a system is to provide students with an efficient and effective learning environment.

  3. Evolving hunting practices in Gabon: lessons for community-based conservation interventions

    Directory of Open Access Journals (Sweden)

    Gretchen Walters

    2015-12-01

    Full Text Available Addressing today's environmental challenges is intimately linked to understanding and improving natural resource governance institutions. As a result conservation initiatives are increasingly realizing the importance of integrating local perspectives of land tenure arrangements, natural resource rights, and local beliefs into conservation approaches. However, current work has not sufficiently considered the dynamic nature of natural resource governance institutions over time and the potential implications for current conservation interventions. We therefore explored how and why hunting governance has changed since the precolonial period in two ethnic hunting communities in Gabon, Central Africa, integrating various ethnographic methods with resource-use mapping, and a historic literature review. In both communities, hunting governance has undergone significant changes since the precolonial period. A closed-access, lineage-based system of resource use with strict penalties for trespassing, has evolved into a more open-access system, in which the influence of customary governance systems, including magico-political aspects, has declined. These changes have occurred mainly in response to policies and governance structures put in place by the colonial government and postindependence, early state laws. This included a policy of merging villages, the introduction of more modern hunting techniques such as guns and wire cables, and a shift from community to government ownership of the land. Current governance structures are thus the product of a complex mixture of customary, colonial and state influences. These findings suggest that a historical perspective of resource governance, gained through in-depth and long-term engagement with local communities, can provide important insights for community-based conservation approaches, such as helping to identify potential causes and perceptions of environmental change and to design more suitable conservation

    2015-05-01

    Spontaneous turn taking phenomenon can be observed in many self-organized systems, and the mechanism is unclear. This paper tries to model it by evolutionary dilemma games with memory mechanism. Prisoner's dilemma, Snowdrift (including Leader and Hero) and Stag-hunt games are unified on an extended S-T plane. Agents play game with all the others and make decision by the last game histories. The experiments find that when agents remember last 2-step histories or more, a kind of cooperative turn taking (CAD) bursts at the area of Snowdrift game with restriction of S + T > 2R and S ≠ T, while the consistent strategy (DorC) gathers on the line of S + T > 2R and S = T. We also find that the system's fitness ratio greatly improved with 2-step memory. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2008-01-01

    Full text: A review of MRI findings in seven patients with Tolosa-Hunt syndrome was carried out. Seven patients presented with unilateral painful ophthalmoplegia. Magnetic resonance imaging studies were carried out to evaluate the cavernous sinuses and orbits. Coronal fast spin-echo T 2 -weighted images and fat-saturated T 1 -weighted coronal and transverse images with and without contrast enhancement were obtained for the cavernous sinuses and orbits. All patients showed focal-enhancing masses expanding the ipsilateral cavernous sinus. In one patient the mass was extending to the orbital apex and intraorbital. All patients recovered on corticosteroid therapy and resolution of the masses was documented on follow-up MRI studies in five patients. One patient had a relapse of symptoms after discontinuing therapy. Magnetic resonance imaging studies of the cavernous sinus and orbital apex show high sensitivity for the detection and follow up of inflammatory mass lesions in Tolosa-Hunt syndrome. Magnetic resonance imaging should be the initial screening study in these patients.

  16. Warren Hunt to test granite well

    International Nuclear Information System (INIS)

    Harvie, W.

    1996-01-01

    Various theories which purport to explain the existence of the Alberta oil sands, were discussed briefly. One theory, held among others by Warren Hunt, speculates that oil is formed deep in the Precambrian basement and not in the higher sedimentary rock. According to this theory, methane in the crust is the abiogenic product that results from hydrogen reacting with silicon carbide in the lower mantle. As it rises through the fractures, it encounters the microbiota, and hydrogen is stripped away making larger molecules until only bitumen remains. Hunt and other adherents of this theory believe that hydrocarbon reservoirs are replenished as oil is produced, hence there is no end to the world's oil supply. This theory is about to be tested by retesting a granite well near Fort McMurray, which was suspended in September 1994, when funding dried up. Kaleeda Enterprises, owners of the well, believe that the well bottom is currently in a granite pool, and oil will be found by deepening the well to 2,150 metres from the current 1,650 metres. While this is not universally accepted, if true, the abiogenic theory would go a long way towards explaining the origin of the oil sands

    2016-11-01

    Full Text Available In Brief: This article makes connections between the ACRL Framework for Information Literacy for Higher Education and the activity of survey mark hunting. After a brief review of the literature related to geographic information systems (GIS, information literacy, and gamification of learning, the authors enter into a dialogue in which they discover and describe the various ways information literacy is both required by and developed through the recreational activity of survey mark hunting. Through their dialogue they found that the activity of survey mark hunting relies on the construction of both information and its authority in ways contextualized within the communities that participate; that survey mark hunting is a conversation that builds on the past, where lived experience counts as evidence; and, that survey mark hunting is both a metaphor and embodied enactment of information literacy.

  1. Investigating and Promoting Trainee Science Teachers' Conceptual Change of the Nature of Science with Digital Dialogue Games `InterLoc'

    Mansour, Nasser; Wegerif, Rupert; Skinner, Nigel; Postlethwaite, Keith; Hetherington, Lindsay

    2016-10-01

    The purpose of this study is to explore how an online-structured dialogue environment supported (OSDE) collaborative learning about the nature of science among a group of trainee science teachers in the UK. The software used (InterLoc) is a linear text-based tool, designed to support structured argumentation with openers and `dialogue moves'. A design-based research approach was used to investigate multiple sessions using InterLoc with 65 trainee science teachers. Five participants who showed differential conceptual change in terms of their Nature of Science (NOS) views were purposively selected and closely followed throughout the study by using key event recall interviews. Initially, the majority of participants held naïve views of NOS. Substantial and favourable changes in these views were evident as a result of the OSDE. An examination of the development of the five participants' NOS views indicated that the effectiveness of the InterLoc discussions was mediated by cultural, cognitive, and experiential factors. The findings suggest that InterLoc can be effective in promoting reflection and conceptual change.

    The adaptation process of a species to a new environment is a significant area of study in biology. As part of natural selection, adaptation is a mutation process which improves survival skills and reproductive functions of species. Here, we investigate this process by combining the idea of incompetence with evolutionary game theory. In the sense of evolution, incompetence and training can be interpreted as a special learning process. With focus on the social side of the problem, we analyze the influence of incompetence on behavior of species. We introduce an incompetence parameter into a learning function in a single-population game and analyze its effect on the outcome of the replicator dynamics. Incompetence can change the outcome of the game and its dynamics, indicating its significance within what are inherently imperfect natural systems.

    Full Text Available SUMMARY: Ramsay Hunt syndrome is a rare complication of herpes zoster which results from the reactivation of the latent varicella-zoster virus in the geniculate ganglion. Although facial nerve is the most common affected nerve in Ramsay Hunt syndrome, other cranial and cervical nerves can also be affected. We present an atypical case of Ramsay Hunt syndrome in a 42-year-old male, with cervical nerve involvement. As spontaneous recovery rate in Ramsay Hunt syndrome is low, early diagnosis and treatment plays a key role in full recovery of paralysis. ÖZET: Ramsay Hunt sendromu, varisella-zoster virüsün latent olarak kaldığı genikulat ganglionda aktifleşmesiyle oluşan herpes zosterin nadir bir komplikasyonudur. Ramsay Hunt sendromunda fasiyal sinir en sık etkilenen sinir olmasına rağmen diğer kraniyal sinirler ve servikal sinirler de tutulabilir. Bu yazıda, 42 yaşındaki erkek hastada servikal tutulumun da eşlik ettiği atipik bir Ramsay Hunt sedromu olgusu sunuldu. Ramsay Hunt sedromunda spontan iyileşme oranları düşük olduğundan bu hastaların tanılarının erken dönemde konması ve tedavilerinin hemen başlanması paralizinin tam olarak iyileşmesinde kilit role sahiptir.

    Full Text Available Whereas past wolf management in the United States was restricted to recovery, managers must now contend with publicly contentious post-recovery issues including regulated hunting seasons. Understanding stakeholder concerns associated with hunting can inform stakeholder engagement, communication, and policy development and evaluation. Social identity theory (SIT has been used to understand how groups interact, why they conflict, and how collaboration may be achieved. Applying SIT to stakeholder conflicts about wolf hunting may help delineate groups according to their concern about, support for or opposition to the policy choice of hunting wolves. Our objective was to assess concerns about hunting as a tool to resolve conflict in Michigan, using SIT as a framework. We used a mixed-modal sampling approach (e.g., paper, Internet with wolf hunting-related public meeting participants in March 2013. Survey questions focused on 12 concerns previously identified as associated with hunting as a management tool to resolve conflict. Respondents (n  =  666 cared greatly about wolves but were divided over hunting wolves. Wolf conflicts, use of science in policy decisions, and maintaining a wolf population were the highest ranked concerns. Principle components analysis reduced concerns into three factors that explained 50.7% of total variance; concerns crystallized over justifications for hunting. General linear models revealed a lack of geographic influence on care, fear and support for hunting related to wolves. These findings challenge assumptions about regional differences and suggest a strong role for social identity in driving dichotomized public perceptions in wildlife management.

    Wildlife subsistence hunting is a major source of protein for tropical rural populations and a prominent conservation issue. The intrinsic rate of natural increase. (r max ) of populations is a key reproductive parameter in the most used assessments of hunting sustainability. However, researchers face severe difficulties in obtaining reproductive data in the wild, so these assessments often rely on classic reproductive rates calculated mostly from studies of captive animals conducted 30 years ago. The result is a flaw in almost 50% of studies, which hampers management decision making. We conducted a 15-year study in the Amazon in which we used reproductive data from the genitalia of 950 hunted female mammals. Genitalia were collected by local hunters. We examined tissue from these samples to estimate birthrates for wild populations of the 10 most hunted mammals. We compared our estimates with classic measures and considered the utility of the use of r max in sustainability assessments. For woolly monkey (Lagothrix poeppigii) and tapir (Tapirus terrestris), wild birthrates were similar to those from captive populations, whereas birthrates for other ungulates and lowland-paca (Cuniculus paca) were significantly lower than previous estimates. Conversely, for capuchin monkeys (Sapajus macrocephalus), agoutis (Dasyprocta sp.), and coatis (Nasua nasua), our calculated reproductive rates greatly exceeded often-used values. Researchers could keep applying classic measures compatible with our estimates, but for other species previous estimates of r max may not be appropriate. We suggest that data from local studies be used to set hunting quotas. Our maximum rates of population growth in the wild correlated with body weight, which suggests that our method is consistent and reliable. Integration of this method into community-based wildlife management and the training of local hunters to record pregnancies in hunted animals could efficiently generate useful information of life

    2014-01-01

    This text serves as a thorough introduction to the rapidly developing field of positional games. This area constitutes an important branch of combinatorics, whose aim it is to systematically develop an extensive mathematical basis for a variety of two-player perfect information games. These range from such popular games as Tic-Tac-Toe and Hex to purely abstract games played on graphs and hypergraphs. The subject of positional games is strongly related to several other branches of combinatorics such as Ramsey theory, extremal graph and set theory, and the probabilistic method. These notes cover a variety of topics in positional games, including both classical results and recent important developments. They are presented in an accessible way and are accompanied by exercises of varying difficulty, helping the reader to better understand the theory. The text will benefit both researchers and graduate students in combinatorics and adjacent fields.

    Full Text Available Venison is becoming more and more interesting for consumers. Although treatment procedures of hunted game differ from slaughtered livestock, the hygienic quality of game meat must still be ensured. Potential indicators of meat hygienic quality include the content of biogenic amines. The aim of the present study was to assess the content and changes of biogenic amines in the muscles of selected kinds of small game (common pheasant and brown hare during storage, and based on the obtained results, to assess the hygienic quality of the meat. Biogenic amines (putrescine, cadaverine, histamine, tyramine, phenylethylamine, and tryptamine in the breast and thigh muscles separated by reverse phase liquid chromatography and consequently were detected using tandem mass spectrometry. Based on the determined content of biogenic amines, both pheasant and hare meats complied with values of high quality meat. The sum of biogenic amines did not exceed the value of 5 mg/kg after 7 days at 0 °C or 7 °C in pheasant meat, and after 21 days at 0 °C or after 14 days at 7 °C in brown hare meat. The biogenic amine content and the speed of their formation in venison can be very helpful for the evaluation of both meat hygienic quality and safety of these foods during storage.

  10. Games are motivating, aren´t they? Disputing the arguments for digital game-based learning

    2015-06-01

    Full Text Available The growing popularity of game-based learning reflects the burning desire for exploiting the involving and motivating characteristics of games for serious purposes. A wide range of arguments for using games for teaching and learning can be encountered in scientific papers, policy reports, game reviews and advertisements. With contagious enthusiasm, the proponents of game-based learning make their claims for using games to improve education. However, standing up for a good cause is easily replaced with the unconcerned promotion and spread of the word, which tends to make gaming an article of faith. This paper critically examines and re-establishes the argumentation used for game-based learning and identifies misconceptions that confuse the discussions. It reviews the following claims about game-based learning: 1 games foster motivation, 2 play is a natural mode of learning, 3 games induce cognitive flow, which is productive for learning, 4 games support learning-by-doing, 5 games allow for performance monitoring, 6 games offer freedom of movement and the associated problem ownership, 7 games support social learning, 8 games allow for safe experimentation, 9 games accommodate new generations of learners, who have grown up immersed in digital media, and 10 there are many successful games for learning. Assessing the validity of argumentation is considered essential for the credibility of game-based learning as a discipline.

    Background Lead-free hunting bullets are an alternative to lead-containing bullets which cause health risks for humans and endangered scavenging raptors through lead ingestion. However, doubts concerning the effectiveness of lead-free hunting bullets hinder the wide-spread acceptance in the hunting and wildlife management community. Methods We performed terminal ballistic experiments under standardized conditions with ballistic soap as surrogate for game animal tissue to characterize dimensionally stable, partially fragmenting, and deforming lead-free bullets and one commonly used lead-containing bullet. The permanent cavities created in soap blocks are used as a measure for the potential wound damage. The soap blocks were imaged using computed tomography to assess the volume and shape of the cavity and the number of fragments. Shots were performed at different impact speeds, covering a realistic shooting range. Using 3D image segmentation, cavity volume, metal fragment count, deflection angle, and depth of maximum damage were determined. Shots were repeated to investigate the reproducibility of ballistic soap experiments. Results All bullets showed an increasing cavity volume with increasing deposited energy. The dimensionally stable and fragmenting lead-free bullets achieved a constant conversion ratio while the deforming copper and lead-containing bullets showed a ratio, which increases linearly with the total deposited energy. The lead-containing bullet created hundreds of fragments and significantly more fragments than the lead-free bullets. The deflection angle was significantly higher for the dimensionally stable bullet due to its tumbling behavior and was similarly low for the other bullets. The deforming bullets achieved higher reproducibility than the fragmenting and dimensionally stable bullets. Conclusion The deforming lead-free bullet closely resembled the deforming lead-containing bullet in terms of energy conversion, deflection angle, cavity shape

  16. Road development and the geography of hunting by an Amazonian indigenous group: consequences for wildlife conservation.

    Santiago Espinosa

    Full Text Available Protected areas are essential for conservation of wildlife populations. However, in the tropics there are two important factors that may interact to threaten this objective: 1 road development associated with large-scale resource extraction near or within protected areas; and 2 historical occupancy by traditional or indigenous groups that depend on wildlife for their survival. To manage wildlife populations in the tropics, it is critical to understand the effects of roads on the spatial extent of hunting and how wildlife is used. A geographical analysis can help us answer questions such as: How do roads affect spatial extent of hunting? How does market vicinity relate to local consumption and trade of bushmeat? How does vicinity to markets influence choice of game? A geographical analysis also can help evaluate the consequences of increased accessibility in landscapes that function as source-sink systems. We applied spatial analyses to evaluate the effects of increased landscape and market accessibility by road development on spatial extent of harvested areas and wildlife use by indigenous hunters. Our study was conducted in Yasuní Biosphere Reserve, Ecuador, which is impacted by road development for oil extraction, and inhabited by the Waorani indigenous group. Hunting activities were self-reported for 12-14 months and each kill was georeferenced. Presence of roads was associated with a two-fold increase of the extraction area. Rates of bushmeat extraction and trade were higher closer to markets than further away. Hunters located closer to markets concentrated their effort on large-bodied species. Our results clearly demonstrate that placing roads within protected areas can seriously reduce their capacity to sustain wildlife populations and potentially threaten livelihoods of indigenous groups who depend on these resources for their survival. Our results critically inform current policy debates regarding resource extraction and road building

    2012-01-01

    The framework for playing quantum games in an Einstein-Podolsky-Rosen (EPR) type setting is investigated using the mathematical formalism of geometric algebra (GA). The main advantage of this framework is that the players' strategy sets remain identical to the ones in the classical mixed-strategy version of the game, and hence the quantum game becomes a proper extension of the classical game, avoiding a criticism of other quantum game frameworks. We produce a general solution for two-player games, and as examples, we analyze the games of Prisoners' Dilemma and Stag Hunt in the EPR setting. The use of GA allows a quantum-mechanical analysis without the use of complex numbers or the Dirac Bra-ket notation, and hence is more accessible to the non-physicist.

    The game statistics for the island of Olkiluoto were updated in the spring 2010, and compared with earlier studies. Population size estimates are based on interviews of local hunters, and on other material available. No elk nor deer inventories were made in the winter 2009-2010. The elk population is still slightly decreasing. The white-tailed deer population was made smaller by hunting. The changes in the roe deer population are not known accurately, but population size varies somewhat from year to year. The number of hunted small predators approximately doubled in the latest hunting season. Altogether 17 waterfowl were hunted in 2009 (none in the previous year). The populations of mountain hare and red squirrel are abundant. The brown hare population is still small, even though there was one brood in Olkiluoto in 2009. (orig.)

    The standard model of particle theory will be rigorously tested by upcoming precision data on flavor mixing. Although the unitarity triangles (UTs) carry information about the Kobayashi-Maskawa (KM) quark mixing matrix, it explicitly contains just three parameters which is one short to completely fix the KM matrix. We have recently shown that the unitarity boomerangs (UBs) formed using two UTs, with a common inner angle, can completely determine the KM matrix and, therefore, better represents quark mixing. Out of the total 18 possible UBs, there is only one that does not involve very small angles and is the ideal one for practical uses. Although the UBs have different areas, there is, however, an invariant quantity, for all UBs, which is equal to a quarter of the Jarlskog parameter J squared. Hunting for new physics, with a unitarity boomerang, can reveal more information, than just using a UTs.

  4. Bear-baiting may exacerbate wolf-hunting dog conflict.

    Directory of Open Access Journals (Sweden)

    Joseph K Bump

    Full Text Available BACKGROUND: The influence of policy on the incidence of human-wildlife conflict can be complex and not entirely anticipated. Policies for managing bear hunter success and depredation on hunting dogs by wolves represent an important case because with increasing wolves, depredations are expected to increase. This case is challenging because compensation for wolf depredation on hunting dogs as compared to livestock is less common and more likely to be opposed. Therefore, actions that minimize the likelihood of such conflicts are a conservation need. METHODOLOGY/PRINCIPAL FINDINGS: We used data from two US states with similar wolf populations but markedly different wolf/hunting dog depredation patterns to examine the influence of bear hunting regulations, bear hunter to wolf ratios, hunter method, and hunter effort on wolf depredation trends. Results indicated that the ratio of bear hunting permits sold per wolf, and hunter method are important factors affecting wolf depredation trends in the Upper Great Lakes region, but strong differences exist between Michigan and Wisconsin related in part to the timing and duration of bear-baiting (i.e., free feeding. The probability that a wolf depredated a bear-hunting dog increases with the duration of bear-baiting, resulting in a relative risk of depredation 2.12-7.22× greater in Wisconsin than Michigan. The net effect of compensation for hunting dog depredation in Wisconsin may also contribute to the difference between states. CONCLUSIONS/SIGNIFICANCE: These results identified a potential tradeoff between bear hunting success and wolf/bear-hunting dog conflict. These results indicate that management options to minimize conflict exist, such as adjusting baiting regulations. If reducing depredations is an important goal, this analysis indicates that actions aside from (or in addition to reducing wolf abundance might achieve that goal. This study also stresses the need to better understand the relationship

    The article deals with determination of Hg in the biological materials (furred game), which comes from 9 districts in Slovak Republic. In the fur there were determined the mercury contents, in μg·kg -1 , as follows: roe deer game - Lucenec District, 12.3; Poltar Dis., 12.8; Prievidza Dis., 42.6; Revuca Dis., 23.5; Rimavska Sobota Dis., 16.7; Spisska Nova Ves Dis., 262.5; Veliky Krtis Dis., 20.3; Zarnovica Dis., 11.5; Ziar nad Hronom Dis., 15.5; red deer game - Lucenec Dis., 13.6; Poltar Dis., 16.2; Rimavska Sobota Dis., 22.1; Zarnovica Dis., 9.6; fallow deer game - Poltar Dis., 41.9; boar game - Prievidza Dis., 257.6. The measurements were carried out by atomic absorption spectrometry using an AMA 254 instrument. The investigated animals were hunted during the hunting period in the year 1999. The biological samples were taken from healthy game without any strange changes of its behavior or colour. High mercury content in fur of roe deer game in Spisska Nova Ves District and also in fur of boar game in Prievidza District shows big air pollution in these districts, caused mainly by intensive industry, mining, reprocessing and energy technologies used in these districts. We can suppose that because of the environmental contamination there is also a high content of mercury in game internal organs. It would be useful to continue with analyzing the content of Hg in the biological material and environmental as well. (author)

    Pressure to ban the hunting of foxes with hounds in Britain has fuelled debate about its contribution to the control of fox populations. We took advantage of a nationwide one-year ban on fox-hunting during the outbreak of foot-and-mouth disease (FMD) in 2001 to examine this issue and found that the ban had no measurable impact on fox numbers in randomly selected areas. Our results argue against suggestions that fox populations would increase markedly in the event of a permanent ban on hunting.

It is not clear whether video game playing meets diagnostic criteria for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). First objective is to review the literature on computer and video game addiction over the topics of diagnosis, phenomenology, epidemiology, and treatment. Second objective is to describe a brain imaging study measuring dopamine release during computer game playing. Article search of 15 published articles between 2000 and 2009 in Medline and PubMed on computer and video game addiction. Nine abstinent "ecstasy" users and 8 control subjects were scanned at baseline and after performing on a motorbike riding computer game while imaging dopamine release in vivo with [123I] IBZM and single photon emission computed tomography (SPECT). Psycho-physiological mechanisms underlying computer game addiction are mainly stress coping mechanisms, emotional reactions, sensitization, and reward. Computer game playing may lead to long-term changes in the reward circuitry that resemble the effects of substance dependence. The brain imaging study showed that healthy control subjects had reduced dopamine D2 receptor occupancy of 10.5% in the caudate after playing a motorbike riding computer game compared with baseline levels of binding consistent with increased release and binding to its receptors. Ex-chronic "ecstasy" users showed no change in levels of dopamine D2 receptor occupancy after playing this game. This evidence supports the notion that psycho-stimulant users have decreased sensitivity to natural reward. Computer game addicts or gamblers may show reduced dopamine response to stimuli associated with their addiction presumably due to sensitization.

  12. An application of evolutionary game theory to social dilemmas: the traveler's dilemma and the minimum effort coordination game.

    Directory of Open Access Journals (Sweden)

    Swami Iyer

    Full Text Available The Traveler's Dilemma game and the Minimum Effort Coordination game are two social dilemmas that have attracted considerable attention due to the fact that the predictions of classical game theory are at odds with the results found when the games are studied experimentally. Moreover, a direct application of deterministic evolutionary game theory, as embodied in the replicator dynamics, to these games does not explain the observed behavior. In this work, we formulate natural variants of these two games as smoothed continuous-strategy games. We study the evolutionary dynamics of these continuous-strategy games, both analytically and through agent-based simulations, and show that the behavior predicted theoretically is in accord with that observed experimentally. Thus, these variants of the Traveler's Dilemma and the Minimum Effort Coordination games provide a simple resolution of the paradoxical behavior associated with the original games.

    2014-09-01

    Full Text Available James Lovelock’s vision of Earth as a living cybernetic system is popular again. The surprising new preacher of Gaia is Bruno Latour. He uses the concept to refer to a holistic understanding of Earth, in which mankind is situated as integral part. Gaia becomes the catalyst and fundament for his philosophical attempt to design a new believe-system in the time of ecological crisis. But the concept of Gaia is characterised by a tension between the idea of a powerful but indifferent nature and a grandiose vision of total control over it. This tension reveals itself to be deeply rooted in cybernetic thought. It is not only apparent in Lovelock’s own writing, but also in simulation programs based on the Gaia hypothesis such as the Daisyworld model and the computer game “SimEarth: The Living Planet” (1991. The article will distinguish Lovelock’s from Latour’s concept of Gaia and relate them to first- and second order cybernetics as well as to two different approaches to computer simulation: system dynamics and cellular automata.

    New kinds of knowledge, usage patterns and management strategies of natural resources emerge in local communities as a way of coping with uncertainty in a changing world. Studying how human groups adapt and create new livelihoods strategies are important research topics for creating policies in natural resources management. Here, we study the adoption and development of lagartos (Crocodylus moreletii) commercial hunting by Mayan people from a communal land in Quintana Roo state. Two questions guided our work: how did the Mayan learn to hunt lagartos? And how, and in what context, did knowledge and management practices emerge? We believe that social structures, knowledge and preexisting skills facilitate the hunting learning process, but lagarto ecological knowledge and organizational practice were developed in a "learning by doing" process. We conducted free, semi-structured and in-depth interviews over 17 prestigious lagartos hunters who reconstructed the activity through oral history. Then, we analyzed the sources of information and routes of learning and investigated the role of previous knowledge and social organization in the development of this novel activity. Finally, we discussed the emergence of hunting in relation to the characteristic of natural resource and the tenure system. Lagarto hunting for skin selling was a short-term activity, which represented an alternative source of money for some Mayans known as lagarteros. They acquired different types of knowledge and skills through various sources of experience (individual practice, or from foreign hunters and other Mayan hunters). The developed management system involved a set of local knowledge about lagartos ecology and a social organization structure that was then articulated in the formation of "working groups" with particular hunting locations (rumbos and trabajaderos), rotation strategies and collaboration among them. Access rules and regulations identified were in an incipient state of development

    Full Text Available This paper discusses the expressions used to refer to the experience of immersive in narrative games. The starting point is a review of the meanings associated with the suspension of disbelief in literature, cinema and television, challenging the myth of the naïve audience that cannot distinguish between representation and reality. Two characteristics of interactive media narratives – the possibility of agency and the disparities between hardware and software interfaces – reveal the active nature of the audience’s involvement with media representations. It is proposed that, in the case of games, this ability, which allows for simultaneous actions in the world of games and in the real world, is better described as a performance of belief.

    Highlights: • A novel distributed autonomous virtual tribes control system is proposed. • WPH-VTC strategy is designed to solve the distributed virtual tribes control. • Stochastic consensus game on mixed homogeneous and heterogeneous multi-agent are resolved. • The optimal total power reference and its dispatch are resolved simultaneously in a dynamic way. • The utilization rate of renewable energy is increased with a reduced carbon emissions. - Abstract: This paper proposes a novel electric power autonomy to satisfy the requirement of power generation optimization of smart grid and decentralized energy management system. A decentralized virtual tribes control (VTC) is developed which can effectively coordinate the regional dispatch centre and the distributed energy. Then a wolf pack hunting (WPH) strategy based VTC (WPH-VTC) is designed through combining the multi-agent system stochastic game and multi-agent system collaborative consensus, which is called the multi-agent system stochastic consensus game, to achieve the coordination and optimization of the decentralized VTC, such that different types of renewable energy can be effectively integrated into the electric power autonomy. The proposed scheme is implemented on a flexible and dynamic multi-agent stochastic game-based VTC simulation platform, which control performance is evaluated on a typical two-area load–frequency control power system and a practical Guangdong power grid model in southern China. Simulation results verify that it can improve the closed-loop system performances, increase the utilization rate of the renewable energy, reduce the carbon emissions, and achieve a fast convergence rate with significant robustness compared with those of existing schemes.

  9. Preventing Philippine Eagle hunting: what are we missing?

    Jayson Ibanez

    2016-11-01

    Full Text Available Two pieces of information are minimally required to conserve endangered raptor species — (i an estimate of its remaining global population, and (ii the main factors responsible for its decline. Data suggest that no more than 400 adult pairs of the Critically Endangered Philippine Eagle could remain in the wild. As to what is causing population decline, shooting and hunting continue to be the primary factor while forest habitat loss is another. This paper reflects on the growing incident of human-caused deaths in Philippine Eagles, prominently on Mindanao Island where estimates suggest more than half of the eagle’s wild population exists. By analyzing data from eagle rescues, surveys, and field monitoring through radio and satellite tracking techniques, this paper shows that shooting and trapping is a “clear and present” danger which may potentially drive the population to extinction even when suitable forest habitats still exist. Cases of death within the last decade show that the nature and/or extent of law enforcement, conservation education, and population and habitat monitoring fall short of being effective deterrents to eagle persecution in the wild. We review emerging theories on wildlife crime and cases of community-based species conservation to justify a holistic and grounded approach to preventing eagle poaching as an alternative to the conservation status quo. 

  10. African wildlife conservation and the evolution of hunting institutions

    Hunting regulation presents a significant challenge for contemporary global conservation governance. Motivated by various incentives, hunters may act legally or illegally, for or against the interests of conservation. Hunter incentives are shaped by the interactions between unevenly evolving formal and informal institutions, embedded in socio-ecological systems. To work effectively for conservation, regulatory interventions must take these evolving institutional interactions into account. Drawing on analytical tools from evolutionary institutional economics, this article examines the trajectory of African hunting regulation and its consequences. Concepts of institutional dynamics, fit, scale, and interplay are applied to case studies of rhinoceros and lion hunting to highlight issues of significance to conservation outcomes. These include important links between different forms of hunting and dynamic interplay with institutions of trade. The case studies reveal that inappropriate formal regulatory approaches may be undermined by adaptive informal market responses. Poorly regulated hunting may lead to calls for stricter regulations or bans, but such legal restrictions may in turn perversely lead to more intensified and organised illegal hunting activity, further undermining conservation objectives. I conclude by offering insights and recommendations to guide more effective future regulatory interventions and priorities for further research. Specifically, I advocate approaches that move beyond simplistic regulatory interventions toward more complex, but supportive, institutional arrangements that align formal and informal institutions through inclusive stakeholder engagement.

  11. Lionfish predators use flared fin displays to initiate cooperative hunting.

    Despite considerable study, mystery surrounds the use of signals that initiate cooperative hunting in animals. Using a labyrinth test chamber, we examined whether a lionfish, Dendrochirus zebra, would initiate cooperative hunts with piscine partners. We found that D. zebra uses a stereotyped flared fin display to alert conspecific and heterospecific lionfish species Pterois antennata to the presence of prey. Per capita success rate was significantly higher for cooperative hunters when compared with solitary ones, with hunt responders assisting hunt initiators in cornering the prey using their large extended pectoral fins. The initiators would most often take the first strike at the group of prey, but both hunters would then alternate striking at the remaining prey. Results suggest that the cooperative communication signal may be characteristic to the lionfish family, as interspecific hunters were equally coordinated and successful as intraspecific hunters. Our findings emphasize the complexity of collaborative foraging behaviours in lionfish; the turn-taking in strikes suggests that individuals do not solely try to maximize their own hunting success: instead they equally share the resources between themselves. Communicative group hunting has enabled Pteroine fish to function as highly efficient predators. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

    Extrasolar moons may be frequent temperate abodes for life and their detection would not only have astrobiological significance but would also greatly further our understanding of planet/moon formation theories. To date, the bulk of research on this topic has been mostly theoretical, focussing on detection techniques and expected sensitivities as well as exomoon origin and evolution. Here, we introduce a new observational project which aims to change this, enabled by the fact both the theory and available instrumentation have evolved to the required level to make such a search feasible. Our project, "The Hunt for Exomoons with Kepler” (HEK), will be a systematic search for exomoons around planets which are viable hosts, with the explicit goal of determining the frequency of large exomoons in the cosmos. We will overview the observational strategy including the detection tools and target selection routines which have been developed, methods to vet false-positives, and some preliminary results from our first batch of candidates. This research is enabled by the NASA Carl Sagan fellowships for exoplanetary research.

    2007-01-01

    Symmetric quantum games for 2-player, 2-qubit strategies are analyzed in detail by using a scheme in which all pure states in the 2-qubit Hilbert space are utilized for strategies. We consider two different types of symmetric games exemplified by the familiar games, the Battle of the Sexes (BoS) and the Prisoners' Dilemma (PD). These two types of symmetric games are shown to be related by a duality map, which ensures that they share common phase structures with respect to the equilibria of the strategies. We find eight distinct phase structures possible for the symmetric games, which are determined by the classical payoff matrices from which the quantum games are defined. We also discuss the possibility of resolving the dilemmas in the classical BoS, PD, and the Stag Hunt (SH) game based on the phase structures obtained in the quantum games. It is observed that quantization cannot resolve the dilemma fully for the BoS, while it generically can for the PD and SH if appropriate correlations for the strategies of the players are provided

  19. To dare or not to dare? Risk management by owls in a predator-prey foraging game.

    2014-07-01

    In a foraging game, predators must catch elusive prey while avoiding injury. Predators manage their hunting success with behavioral tools such as habitat selection, time allocation, and perhaps daring-the willingness to risk injury to increase hunting success. A predator's level of daring should be state dependent: the hungrier it is, the more it should be willing to risk injury to better capture prey. We ask, in a foraging game, will a hungry predator be more willing to risk injury while hunting? We performed an experiment in an outdoor vivarium in which barn owls (Tyto alba) were allowed to hunt Allenby's gerbils (Gerbillus andersoni allenbyi) from a choice of safe and risky patches. Owls were either well fed or hungry, representing the high and low state, respectively. We quantified the owls' patch use behavior. We predicted that hungry owls would be more daring and allocate more time to the risky patches. Owls preferred to hunt in the safe patches. This indicates that owls manage risk of injury by avoiding the risky patches. Hungry owls doubled their attacks on gerbils, but directed the added effort mostly toward the safe patch and the safer, open areas in the risky patch. Thus, owls dared by performing a risky action-the attack maneuver-more times, but only in the safest places-the open areas. We conclude that daring can be used to manage risk of injury and owls implement it strategically, in ways we did not foresee, to minimize risk of injury while maximizing hunting success.

    2017-09-01

    The relative impacts of hunting and habitat on waterbird community were studied in agricultural wetlands of southern India. We surveyed wetlands to document waterbird community, and interviewed hunters to document hunting intensity, targeted species, and the motivations for hunting. Our results show that hunting leads to drastic declines in waterbird diversity and numbers, and skew the community towards smaller species. Hunting intensity, water spread, and vegetation cover were the three most important determinants of waterbird abundance and community structure. Species richness, density of piscivorous species, and medium-sized species (31-65 cm) were most affected by hunting. Out of 53 species recorded, 47 were hunted, with a preference for larger birds. Although illegal, hunting has increased in recent years and is driven by market demand. This challenges the widely held belief that waterbird hunting in India is a low intensity, subsistence activity, and undermines the importance of agricultural wetlands in waterbird conservation.

    Overexploitation of wildlife populations occurs across the humid tropics and is a significant threat to the long-term survival of large-bodied primates. To investigate the impacts of hunting on primates and ways to mitigate them, we developed a spatially explicit, individual-based model for a landscape that included hunted and un-hunted areas. We used the large-bodied neotropical red howler monkey (Alouatta seniculus) as our case study species because its life history characteristics make it vulnerable to hunting. We modeled the influence of different rates of harvest and proportions of landscape dedicated to un-hunted reserves on population persistence, population size, social dynamics, and hunting yields of red howler monkeys. In most scenarios, the un-hunted populations maintained a constant density regardless of hunting pressure elsewhere, and allowed the overall population to persist. Therefore, the overall population was quite resilient to extinction; only in scenarios without any un-hunted areas did the population go extinct. However, the total and hunted populations did experience large declines over 100 years under moderate and high hunting pressure. In addition, when reserve area decreased, population losses and losses per unit area increased disproportionately. Furthermore, hunting disrupted the social structure of troops. The number of male turnovers and infanticides increased in hunted populations, while birth rates decreased and exacerbated population losses due to hunting. Finally, our results indicated that when more than 55% of the landscape was harvested at high (30%) rates, hunting yields, as measured by kilograms of biomass, were less than those obtained from moderate harvest rates. Additionally, hunting yields, expressed as the number of individuals hunted/year/km2, increased in proximity to un-hunted areas, and suggested that dispersal from un-hunted areas may have contributed to hunting sustainability. These results indicate that un-hunted

Para diferentes flujos y temperaturas de entrada de la mezcla reactiva, se midieron las concentraciones de CH4, CO2 y CO en los gases de combustión con un analizador de gases tipo infrarrojo no dispersivo (NDIR. Para alcanzar conversión total de metano se requirió aumentar la temperatura de entrada al lecho a medida que se incrementó el flujo de gases reaccionantes. Los resultados obtenidos permiten desarrollar un sistema de combustión catalítica de bajo costo con un material térmicamente estable, que promueva la alta eficiencia en la combustión de gas natural y elimine los problemas de estabilidad, seguridad y de impacto ambiental negativo inherentes a los procesos de combustión térmica convencional.

    Full Text Available Ștefan cel Mare University’s Hunting Funds, through the Faculty of Forestry, consists of three hunting territories (HT: HT no. 55 Mitoc, HT no. 69 Râșca, HT no. 56 Salcea. The first two have a high hunting potential for major hunting sedentary game species (wild boar, roe buck, roe deer, hare, wolf, bear. In over 15 years of hunting management, USV has overcome the difficulties imposed by different legislations. Also, USV, along with the University of Brașov, managed to amend Law 407/2006 and to return to free hunting use of the public lands. The teaching and research activities in the hunting territories have resulted in over 15 diploma projects, over 20 scientific articles published in specialized reviews, of which 7 ISI, over 10 scientific papers of which two were the students’ work, two research contracts and a book. The management coherence driven by the specialized staff is reflected in the higher number of top quality trophies, which started to be harvested after about 10 years of management.

  11. Thresher sharks use tail-slaps as a hunting strategy.

    2013-01-01

    The hunting strategies of pelagic thresher sharks (Alopias pelagicus) were investigated at Pescador Island in the Philippines. It has long been suspected that thresher sharks hunt with their scythe-like tails but the kinematics associated with the behaviour in the wild are poorly understood. From 61 observations recorded by handheld underwater video camera between June and October 2010, 25 thresher shark shunting events were analysed. Thresher sharks employed tail-slaps to debilitate sardines at all times of day. Hunting events comprised preparation, strike, wind-down recovery and prey item collection phases, which occurred sequentially. Preparation phases were significantly longer than the others, presumably to enable a shark to windup a tail-slap. Tail-slaps were initiated by an adduction of the pectoral fins, a manoeuvre that changed a thresher shark's pitch promoting its posterior region to lift rapidly, and stall its approach. Tail-slaps occurred with such force that they may have caused dissolved gas to diffuse out of the water column forming bubbles. Thresher sharks were able to consume more than one sardine at a time, suggesting that tail-slapping is an effective foraging strategy for hunting schooling prey. Pelagic thresher sharks appear to pursue sardines opportunistically by day and night, which may make them vulnerable to fisheries. Alopiids possess specialist pectoral and caudal fins that are likely to have evolved, at least in part, for tail-slapping. The evidence is now clear; thresher sharks really do hunt with their tails.

  12. Long-Term Changes in Game Species Over a Long Period of Transformation in the Iberian Mediterranean Landscape

    Agricultural change has transformed large areas of traditional farming landscapes, leading to important changes in the species community assemblages in most European countries. We suspect that the drastic changes in land-use that have occurred in Andalusia (southern Spain) over recent decades, may have affected the distribution and abundance of game species in this region. This article compares the distribution of the main game species in Andalusia during the 1960s and 1990s, using data from maps available from the Mainland Spanish Fish, Game and National Parks Service and from recent datasets on hunting yield distributions, respectively. Big-game and small-game species were significantly segregated in southern Spain during the 1990s, as two clearly independent chorotypes (groups of species whose abundances are similarly distributed) were obtained from the classification analysis. In contrast, big-game and small-game species were not significantly segregated several decades ago, when there was only one chorotype consisting of small-game species and wild boar. The other three ungulates did not constitute a significant chorotype, as they showed positive correlations with some species in the group mentioned above. These changes seem to be a consequence of the transformations that have occurred in the Iberian Mediterranean landscape over the last few decades. The abandoning of traditional activities, and the consequent formation of dense scrubland and woodland, has led to an expansion of big-game species, and a decrease of small-game species in mountain areas. Moreover, agricultural intensification has apparently depleted small-game species populations in some agricultural areas. On the other hand, the increasingly intensive hunting management could be artificially boosting this segregation between small-game and big-game species. Our results suggest that the conservation and regeneration of traditional agricultural landscapes (like those predominating in the 1960s

    Alterations in predation pressure can have large effects on trophically-structured systems. Modification of predator behaviour via ocean warming has been assessed by laboratory experimentation and metabolic theory. However, the influence of ocean acidification with ocean warming remains largely unexplored for mesopredators, including experimental assessments that incorporate key components of the assemblages in which animals naturally live. We employ a combination of long-term laboratory and mesocosm experiments containing natural prey and habitat to assess how warming and acidification affect the development, growth, and hunting behaviour in sharks. Although embryonic development was faster due to temperature, elevated temperature and CO2 had detrimental effects on sharks by not only increasing energetic demands, but also by decreasing metabolic efficiency and reducing their ability to locate food through olfaction. The combination of these effects led to considerable reductions in growth rates of sharks held in natural mesocosms with elevated CO2, either alone or in combination with higher temperature. Our results suggest a more complex reality for predators, where ocean acidification reduces their ability to effectively hunt and exert strong top-down control over food webs.

    General game players are computer systems able to play strategy games based solely on formal game descriptions supplied at ""runtime"" (n other words, they don't know the rules until the game starts). Unlike specialized game players, such as Deep Blue, general game players cannot rely on algorithms designed in advance for specific games; they must discover such algorithms themselves. General game playing expertise depends on intelligence on the part of the game player and not just intelligence of the programmer of the game player.GGP is an interesting application in its own right.

    Paca (Cuniculus paca Linnaeus, 1766) is the second largest rodent found in Brazil. The quality of the meat and a long tradition of hunting have contributed to the decline of the natural populations of this species. Hunting of paca is strictly prohibited in Brazil, but in spite of this restriction, no forensic tools are available for the identification of the meat. We describe an efficient method, based on single nucleotide polymorphisms of the cytochrome b gene, that can be used to differentiate biological material derived from paca from those of domestic species commonly used as sources of meat. The identification of the presence of C. paca in the samples was 100% reliable.

    Mortenson, W Ben; Sixsmith, Andrew; Kaufman, David

    2017-09-01

    Research on video games' effect on cognition and behaviour has been extensive, yet little research has explored non-digital forms of game playing, especially among older adults. As part of a larger survey on game playing, 886 respondents (≥ age 55) filled out questionnaires about non-digital game play. The study aims were to determine perceived benefits of non-digital game play and to determine socio-demographic factors that might predict perceived benefits. Survey results indicate that non-digital game playing is social in nature and common (73% of respondents) among older adults. Older adults play for fun, but also to help maintain their cognition. Regression analyses indicated various socio-demographic factors - age, education, gender, and race - were independently associated with perceived benefits from game playing. The results thus emphasize the importance of non-digital game playing in this population and suggest that efforts to facilitate game playing may improve social interactions and quality of life.

  11. Risk and ethical concerns of hunting male elephant: behavioural and physiological assays of the remaining elephants.

    Tarryne Burke

    Full Text Available BACKGROUND: Hunting of male African elephants may pose ethical and risk concerns, particularly given their status as a charismatic species of high touristic value, yet which are capable of both killing people and damaging infrastructure. METHODOLOGY/PRINCIPAL FINDINGS: We quantified the effect of hunts of male elephants on (1 risk of attack or damage (11 hunts, and (2 behavioural (movement dynamics and physiological (stress hormone metabolite concentrations responses (4 hunts in Pilanesberg National Park. For eleven hunts, there were no subsequent attacks on people or infrastructure, and elephants did not break out of the fenced reserve. For three focal hunts, there was an initial flight response by bulls present at the hunting site, but their movements stabilised the day after the hunt event. Animals not present at the hunt (both bulls and herds did not show movement responses. Physiologically, hunting elephant bulls increased faecal stress hormone levels (corticosterone metabolites in both those bulls that were present at the hunts (for up to four days post-hunt and in the broader bull and breeding herd population (for up to one month post-hunt. CONCLUSIONS/SIGNIFICANCE: As all responses were relatively minor, hunting male elephants is ethically acceptable when considering effects on the remaining elephant population; however bulls should be hunted when alone. Hunting is feasible in relatively small enclosed reserves without major risk of attack, damage, or breakout. Physiological stress assays were more effective than behavioural responses in detecting effects of human intervention. Similar studies should evaluate intervention consequences, inform and improve best practice, and should be widely applied by management agencies.

    2016-05-01

    We study a generalization of non-local games-which we call extended non-local games -in which the players, Alice and Bob, initially share a tripartite quantum state with the referee. In such games, the winning conditions for Alice and Bob may depend on the outcomes of measurements made by the referee, on its part of the shared quantum state, in addition to Alice and Bob's answers to randomly selected questions. Our study of this class of games was inspired by the monogamy-of-entanglement games introduced by Tomamichel, Fehr, Kaniewski and Wehner, which they also generalize. We prove that a natural extension of the Navascués-Pironio-Acín hierarchy of semidefinite programmes converges to the optimal commuting measurement value of extended non-local games, and we prove two extensions of results of Tomamichel et al.  concerning monogamy-of-entanglement games.

    2014-03-01

    We analyze the pedestrian evacuation of a rectangular room with a single door considering a lattice gas scheme with the addition of behavioral aspects of the pedestrians. The movement of the individuals is based on random and rational choices and is affected by conflicts between two or more agents that want to advance to the same position. Such conflicts are solved according to certain rules closely related to the concept of strategies in game theory, cooperation and defection. We consider game rules analogous to those from the Prisoner's Dilemma and Stag Hunt games, with payoffs associated to the probabilities of the individuals to advance to the selected site. We find that, even when defecting is the rational choice for any agent, under certain conditions, cooperators can take advantage from mutual cooperation and leave the room more rapidly than defectors.

  20. Local Strategy Improvement for Parity Game Solving

    Full Text Available The problem of solving a parity game is at the core of many problems in model checking, satisfiability checking and program synthesis. Some of the best algorithms for solving parity game are strategy improvement algorithms. These are global in nature since they require the entire parity game to be present at the beginning. This is a distinct disadvantage because in many applications one only needs to know which winning region a particular node belongs to, and a witnessing winning strategy may cover only a fractional part of the entire game graph. We present a local strategy improvement algorithm which explores the game graph on-the-fly whilst performing the improvement steps. We also compare it empirically with existing global strategy improvement algorithms and the currently only other local algorithm for solving parity games. It turns out that local strategy improvement can outperform these others by several orders of magnitude.

    Full Text Available Trophy hunting has potential to support conservation financing and contribute towards rural development. We conducted a systematic review of the Zimbabwean trophy hunting perspective spanning from pre-1890 to 2015, by examining the following: (1 evolution of legal instruments, administration, and governance of trophy hunting, (2 significance of trophy hunting in conservation financing and rural development, and (3 key challenges, emerging issues in trophy hunting industry, and future interventions. Our review shows that (i there has been a constant evolution in the policies related to trophy hunting and conservation in Zimbabwe as driven by local and international needs; (ii trophy hunting providing incentives for wildlife conservation (e.g., law enforcement and habitat protection and rural communities’ development. Emerging issues that may affect trophy hunting include illegal hunting, inadequate monitoring systems, and hunting bans. We conclude that trophy hunting is still relevant in wildlife conservation and rural communities’ development especially in developing economies where conservation financing is inadequate due to fiscal constraints. We recommend the promotion of net conservation benefits for positive conservation efforts and use of wildlife conservation credits for the opportunity costs associated with reducing trophy hunting off-take levels and promoting nonconsumptive wildlife use options.

    International Nuclear Information System (INIS)

    Slovic, Paul

    1998-01-01

    In the context of health, safety, and environmental decisions, the concept of risk involves value judgments that reflect much more than just the probability and consequences of the occurrence of an event. This article conceptualizes the act of defining and assessing risk as a game, in which the rules must be socially negotiated within the context of a specific problem. This contextualist view of risk provides insight into why technical approaches to risk management often fail with problems such as those involving radiation and chemicals, where scientific experts and the public disagree on the nature of the risks. It also highlights the need for allowing the interested and affected parties to define and play the game, thus emphasizing the importance of institutional, procedural, and societal processes in risk-management decisions

    The authors review recent research that reveals how today’s video games instantiate naturally and effectively many principles psychologists, neuroscientists, and educators believe critical for learning. A large body of research exists showing that the effects of these games are much broader. In fact, some types of commercial games have been proven to enhance basic perceptual and cognitive skills. These effects are significant enough that educators use these games for such practical, real-worl...

  10. A novel approach to assessing the prevalence and drivers of illegal bushmeat hunting in the serengeti.

    Assessing anthropogenic effects on biological diversity, identifying drivers of human behavior, and motivating behavioral change are at the core of effective conservation. Yet knowledge of people's behaviors is often limited because the true extent of natural resource exploitation is difficult to ascertain, particularly if it is illegal. To obtain estimates of rule-breaking behavior, a technique has been developed with which to ask sensitive questions. We used this technique, unmatched-count technique (UCT), to provide estimates of bushmeat poaching, to determine motivation and seasonal and spatial distribution of poaching, and to characterize poaching households in the Serengeti. We also assessed the potential for survey biases on the basis of respondent perceptions of understanding, anonymity, and discomfort. Eighteen percent of households admitted to being involved in hunting. Illegal bushmeat hunting was more likely in households with seasonal or full-time employment, lower household size, and longer household residence in the village. The majority of respondents found the UCT questions easy to understand and were comfortable answering them. Our results suggest poaching remains widespread in the Serengeti and current alternative sources of income may not be sufficiently attractive to compete with the opportunities provided by hunting. We demonstrate that the UCT is well suited to investigating noncompliance in conservation because it reduces evasive responses, resulting in more accurate estimates, and is technically simple to apply. We suggest that the UCT could be more widely used, with the trade-off being the increased complexity of data analyses and requirement for large sample sizes.

  11. Subsistence hunting for turtles in Northwestern Ecuador

    International Nuclear Information System (INIS)

    Carr, John L; Almendariz, Ana; Simmons, John E; Nielsen, Mark T

    2014-01-01

    We describe the subsistence exploitation of an entire turtle fauna in Esmerald's Province, Ecuador. We collected first hand accounts and witnessed a number of capture techniques used by rural afroecuadorian and chachi inhabitants of the Cayapas Santiago River basin. The diversity of techniques indicated a practical knowledge of the ecology of the species. Chelydra acutirostris, Kinosternon leucostomum, Rhinoclemmys annulata, Melanosterna, and R. nasuta were captured and eaten. Poziando involved cleaning pools in a stream bed during the relatively dry season by removing live plants, organic detritus, and then seining with baskets; we observed R. melanosterna and K. leucostomum captured in this way. Pitfall traps baited with fruit were used to catch R. melanosterna during forays on land. Basket traps (Canasto tortuguero) with a wooden slat funnel across the opening are floated with balsa lashed to the sides. Banana or Xanthosoma leaf bait in the basket traps caught R. melanosterna, R. nasuta, and K. leucostomum. Marshy areas were probed for R. melanosterna and K. leucostomum. Direct capture by hand was also common. Turtles were relished as food items; all turtles captured were consumed, usually in soup or stew. Use of turtles for food in the region was pervasive, perhaps because fish and game populations were depleted.

  12. Olfaction in bird dogs during hunting.

    Science.gov (United States)

    Steen, J B; Mohus, I; Kvesetberg, T; Walløe, L

    1996-05-01

    The ability to catch scent continuously while running, which may be an essential skill for many animals of prey, requires that ambient air flows inward through the nose also during expiration. In this study on bird dogs, the direction of air flow was detected by measuring the temperature in the air inside the nostril. While resting, nose ventilation was synchronous with lung ventilation. While searching for ground scent, the dog was sniffing at a frequency of up to 200 s-1, a strategy which may create turbulence in the nasal passages and thereby enhance transport of scent molecules to the receptors in the ethmoidal cavity. When the bird dog was searching for game while running with its head high against the wind, it maintained a continuous inward air stream through the nose for up to 40s spanning at least 30 respiratory cycles. We suggest that expiratory gas flowing at high velocity from the trachea to the mouth cavity creates a lower pressure than in the nose thus causing an inward air stream through the nose during expiration by a Bernoulli effect.

  15. Sport hunting, predator control and conservation of large carnivores.

    Directory of Open Access Journals (Sweden)

    Craig Packer

    Full Text Available Sport hunting has provided important economic incentives for conserving large predators since the early 1970's, but wildlife managers also face substantial pressure to reduce depredation. Sport hunting is an inherently risky strategy for controlling predators as carnivore populations are difficult to monitor and some species show a propensity for infanticide that is exacerbated by removing adult males. Simulation models predict population declines from even moderate levels of hunting in infanticidal species, and harvest data suggest that African countries and U.S. states with the highest intensity of sport hunting have shown the steepest population declines in African lions and cougars over the past 25 yrs. Similar effects in African leopards may have been masked by mesopredator release owing to declines in sympatric lion populations, whereas there is no evidence of overhunting in non-infanticidal populations of American black bears. Effective conservation of these animals will require new harvest strategies and improved monitoring to counter demands for predator control by livestock producers and local communities.

    Lijek, Rebeccah S; Fankhauser, Sarah C

    2016-03-01

    Primary scientific literature can be difficult to navigate for anyone unfamiliar with its foreign, formal structure. We sought to create a fun, easy learning tool to help familiarize students of all ages with the structure of a scientific article. Our main learning objective was for the student to realize that science writing is formulaic-that specific information is found in predictable locations within an article-and that, with an understanding of the formula, anyone can comfortably navigate any journal article and accurately predict what to expect to find in each section. To this end, we designed a Journal Article Scavenger Hunt that requires the user to find and identify a series of commonplace features of a primary research article. The scavenger hunt activity is quick and easy to implement, and is adaptable to various ages and settings, including the classroom, lab, and at outreach events. The questions in the scavenger hunt can be scaled in difficulty and specificity to suit the instructor's needs. Over many years of using this activity, we have received positive feedback from students of all ages, from elementary school students to lay adult-learners as well as science teachers themselves. By making the unknown seem predictable and approachable, the scavenger hunt helps a variety of audiences feel more comfortable with science and more confident in their ability to engage directly with the scientific literature.

    D'Amato, Maria Eugenia; Alechine, Evguenia; Cloete, Kevin Wesley; Davison, Sean; Corach, Daniel

    2013-03-01

    Wild animals' meat is extensively consumed in South Africa, being obtained either from ranching, farming or hunting. To test the authenticity of the commercial labels of meat products in the local market, we obtained DNA sequence information from 146 samples (14 beef and 132 game labels) for barcoding cytochrome c oxidase subunit I and partial cytochrome b and mitochondrial fragments. The reliability of species assignments were evaluated using BLAST searches in GenBank, maximum likelihood phylogenetic analysis and the character-based method implemented in BLOG. The Kimura-2-parameter intra- and interspecific variation was evaluated for all matched species. The combined application of similarity, phylogenetic and character-based methods proved successful in species identification. Game meat samples showed 76.5% substitution, no beef samples were substituted. The substitutions showed a variety of domestic species (cattle, horse, pig, lamb), common game species in the market (kudu, gemsbok, ostrich, impala, springbok), uncommon species in the market (giraffe, waterbuck, bushbuck, duiker, mountain zebra) and extra-continental species (kangaroo). The mountain zebra Equus zebra is an International Union for Conservation of Nature (IUCN) red listed species. We also detected Damaliscus pygargus, which is composed of two subspecies with one listed by IUCN as 'near threatened'; however, these mitochondrial fragments were insufficient to distinguish between the subspecies. The genetic distance between African ungulate species often overlaps with within-species distance in cases of recent speciation events, and strong phylogeographic structure determines within-species distances that are similar to the commonly accepted distances between species. The reliability of commercial labeling of game meat in South Africa is very poor. The extensive substitution of wild game has important implications for conservation and commerce, and for the consumers making decisions on the basis of

  3. Wildlife resource utilisation at Moremi Game Reserve and Khwai community area in the Okavango Delta, Botswana.

    Science.gov (United States)

    Mbaiwa, Joseph E

    2005-10-01

    This paper uses the concept of sustainable development to examine the utilisation of wildlife resources at Moremi Game Reserve (MGR) and Khwai community area (NG 18/19) in the Okavango Delta, Botswana. Using both secondary and primary data sources, results show that the establishment of MGR in 1963 led to the displacement of Khwai residents from their land; affected Basarwa's hunting and gathering economy; marked the beginning of resource conflicts between Khwai residents and wildlife managers; and, led to the development of negative attitudes of Khwai residents towards wildlife conservation. Since the late 1980s, a predominantly foreign owned tourism industry developed in and around MGR, however, Khwai residents derive insignificant benefits from it and hence resource conflicts increased. In an attempt to address problems of resource conflicts and promote sustainable wildlife utilisation, the Botswana Government adopted the Community-Based Natural Resource Management (CBNRM) programme, which started operating at Khwai village in 2000. The CBNRM programme promotes local participation in natural resource management and rural development through tourism. It is beginning to have benefits to Khwai residents such as income generation, employment opportunities and local participation in wildlife management. These benefits from CBNRM are thus having an impact in the development of positive attitudes of Khwai residents towards wildlife conservation and tourism development. This paper argues that if extended to MGR, CBNRM has the potential of minimising wildlife conflicts between Khwai residents and the wildlife-tourism sectors. This approach may in the process promote the sustainable wildlife use in and around MGR.

This analysis has been conducted through a survey based on in-depth interviews with the stakeholders involved in an Italian local supply chain. Findings derived from this study describe a case study, however, they also represent the potential dynamics of the value of Italian game meat, highlighting that the development of a sustainable local supply chain of this product may represent an economic resource for involved stakeholders.

    Full Text Available Audience: This scavenger hunt/escape room is a didactic activity for emergency medicine residents or fourth-year medical students rotating in emergency medicine. Introduction: Between 2008-2011, 1.1 million patients presented to U.S. emergency departments each year for poisonings,1 including acute ingestions, envenomations, occupational exposures, and overdoses. Toxicologic exposures are considered part of the core curriculum for emergency medicine (EM residents, who must understand the presentation and treatment of such patients.2 Educating residents in a unique, engaging format such as an “escape room” activity provides an alternative to the didactic format of teaching this material, which may build medical knowledge and team rapport amongst residents.3 Objectives: By the end of the activity, learners should be able to: Calculate an anion and osmolal gap. Recognize poisonings amenable to hemodialysis. Interpret EKG changes related to a variety of ingestions, including beta-blockers and calcium channel blockers, digitalis, and tricyclic antidepressants. Recognize poisonous plants and their clinical toxidromes. Calculate loading dose of N-acetylcysteine as antidote for acute acetaminophen ingestion. Collaborate as a team to arrive at solutions of problems. Recognize poisons that have available antidotes Know the clinical effect of various types of snake envenomations. Recognize the toxicity associated with at least four household chemicals. Know the antidotes for six common poisonings. Methods: This didactic exercise is a small group activity, utilizing puzzles to apply toxicology knowledge.

    Game design is an art form that deals with inherently interactive artifacts. Game designers craft games (assembled from rule systems and content), but they really seek to manipulate play: the interaction between games and players. When developing new games that are similar to past games, a designer may rely on previous experience with related designs and relatively easy access to players familiar with conventional design choices. When exploratorily venturing into uncharted territory, uncoveri...

  17. Semi-Commercial and Traditional Hunting of Baar Tribe in Riung, Flores, East Nusa Tenggara

    Hunting is one of the aspects that influence number of wild animals. The article aims at describing semi-comercial and traditional hunting concept of Baar Tribe in East Nusa Tenggara as an alternative for wild animal conservation.  The data collection methods are guided interview, in-depth interview and participant observation. The findings show that in the semi-comercial and traditional hunting concept of Baar Tribe in East Nusa Tenggara, traditional wisdom is represented by hunting techniques and equipments. It is likely that rapid semi-commercial hunting conducted by certain members of Baar tribe causes sharp decline in the population of wild animals. On the other hand, annual traditional hunting which strictly follows traditional code of conduct can maintain Timor deer population in Timor.

    Full Text Available Due to hardware limitations at the origin of the video game industry, each new game was generally coded from the ground up. Years later, from the evolution of hardware and the need for quick game development cycles, spawned the concept of game engine. A game engine is a reusable software layer allowing the separation of common game concepts from the game assets (levels, graphics, etc.. This paper surveys fourteen different game engines relevant today, ranging from the industry-level to the newcomer-friendlier ones.

    2018-03-01

    Games have often been used in the classroom to teach physics ideas and concepts, but there has been less published on games that can be used to teach scientific thinking. D. Maloney and M. Masters describe an activity in which students attempt to infer rules to a game from a history of moves, but the students don't actually play the game. Giving the list of moves allows the instructor to emphasize the important fact that nature usually gives us incomplete data sets, but it does make the activity less immersive. E. Kimmel suggested letting students attempt to figure out the rules to Reversi by playing it, but this game only has two players, which makes it difficult to apply in a classroom setting. Kimmel himself admits the choice of Reversi is somewhat arbitrary. There are games, however, that are designed to make the process of figuring out the rules an integral aspect of play. These games involve more people and require only a deck or two of cards. I present here an activity constructed around the card game Mao, which can be used to help students recognize aspects of scientific thinking. The game is particularly good at illustrating the importance of falsification tests (questions designed to elicit a negative answer) over verification tests (examples that confirm what is already suspected) for illuminating the underlying rules.

    Playing games of any kind, from tennis to board games, it is easy to notice that games are configured in space, often using stripes or a kind of map on a board. Some games are clearly performed within this marked border, while it may be difficult to pinpoint such a visual border in a game like hide....... This makes sense, but also demands that play and non-play can be easily separated. I will examine how games make use of space, and show that the magic circle not only is a viable, though criticized, concept but should be understood as a spatial concept. In order to do this several games are examined, leading...... to introduce a spatial model of the game performance comprising a primary and secondary game space. I will show how new game genres can profit from using this model when designing new games....

  3. Radioactivity of game meat in Finland after the Chernobyl accident in 1986

    Rantavaara, A.; Hyvoenen, T.

    1987-06-01

    Radioactive substances in game meat were studied in summer and early autumn 1986 by the Finnish Centre for Radiation and Nuclear Safety in cooperation with the Finnish Game and Fisheries Research Institute. The concentrations of radioactive cesium and other gamma-emitting nuclides were determined on meat of moose and other cervids and also on small game in various parts of the country before or in the beginning of the hunting season. The most important radionuclides found in the samples were 134 Cs and 137 Cs. In addition to these, 131 I was detected in the first moose meat samples in the spring. None of them was significant as far as the dietary intake of radionuclides is concerned. The transfer of fallout radiocesium to game meat was most efficient in the case of the arctic hare and inland waterfowl; terrestrial game birds and the brown hare belonged to the same category as moose. In 1986 the mean dietary intake via game meat was for 131 Cs 47 Bq per person and for 137 Cs 106 Bq per person. In 1987 the corresponding values were 69 Bq per person for 134 Cs and 180 Bq per person for 137 Cs. The contribution of cervids to the total dietary intake of radiocesium via game meat was 3/4, which was slightly less than their contribution to the annual game bag. On the basis of the preliminary results of this study it was concluded in autumn 1986 that there was no need to restrict hunting in the year 1986/1987. The radiocesium found in the meat of terrestrial game animals did not necessitate any recommendations on their use. As regards the meat of waterfowl caught in the main inland fallout area, it was recommended not to eat more than 20 kg per person

    The late Lower Paleolithic archaeofaunas of Qesem Cave in the southern Levant span 400-200 ka and associate with Acheulo-Yabrudian (mainly Amudian) industries. The large mammals are exclusively Eurasian in origin and formed under relatively cool, moist conditions. The zooarchaeological findings testify to large game hunting, hearth-centered carcass processing and meat sharing during the late Lower Paleolithic, not unlike the patterns known from Middle and Upper Paleolithic caves in the region. Well-defined hearth features are rarely preserved in Qesem Cave, but the heterogeneous distributions of burned bones indicate areas of frequent hearth rebuilding throughout the occupation sequence. The hominins delayed consumption of high quality body parts until they could be moved to the cave, where hearths were hubs of processing activities and social interaction. Paradoxically, the cut marks on the Qesem bones are both more abundant and more randomly oriented than those observed in Middle and Upper Paleolithic cases in the Levant. These results suggest that several individuals were directly involved in cutting meat from the bones and that the social mechanics of meat sharing during the late Lower Paleolithic at Qesem Cave differed from those typical of both the Middle and Upper Paleolithic in the region.

    Full Text Available We studied a case of failure in applying traditional ecological knowledge (TEK in comanagement as the basis for formal hunting regulations. We based the study on the Porcupine Caribou (Rangifer tarandus Herd "let the leaders pass" policy, established for the Dempster Highway of the Western Canadian Arctic, and identified conditions creating barriers in the successful application of TEK through comanagement. Stated as propositions, identified barriers include: (1 the context-specific nature of TEK limits its application in resource management regulations; (2 changes in traditional authority systems, hunting technology, and the social organization of harvesting caribou affect the effectiveness of TEK approaches in a contemporary social setting; (3 indigenous efforts toward self-government and political autonomy limit regional comanagement consensus in a heterogeneous cultural landscape; (4 the mismatch of agency enforcement of hunting regulations and TEK-based education is problematic. We analyzed the case through four historical phases of caribou management, complementing the study with a literature review of TEK and wildlife comanagement to explain why TEK integration of caribou leaders in regulatory resource management fell short of success. Identifying and understanding the social dynamics related to these barriers make apparent solutions for transforming the comanagement process.

Vineyards and grass in rotation with winter cereals were positively associated with the number of hares shot, whereas industrial crops (mainly sunflowers seemed to have a negative effect,as did the density of grazing sheep. Mean annual rainfall was negatively related to the harvest but with a borderline significance. We found a positive relationship between the number of hares harvested and the percentage of protected areas managed to conserve and produce small game species, whereas private hunting estates showed a negative association. Restocking both with wild hares captured in protected areas and with farm-reared animals did not show any effect on hunting bags of hares.

    Full Text Available Although nature conservation is a well recognized topic at present, it is not a new phenomenon. Throughout history, there are numerous examples of efforts made by governments, rulers, or individual land owners to protect certain land areas that possessed unique natural values. While many of these areas were actually isolated as game preserves for hunting, they were also designed to conserve wildlife. The establishment of Yellowstone National Park in 1972 marks the modern concept of a national park as it was designed on a very large protected natural area. Presently, one of the most efficient ways for nature protection is “area conservation approach” that many organizations have been developing various systems and categories about. Unfortunately, in spite of such improvements and the extension of the protected area network, many of these areas are not properly protected and/or managed in some countries. This study summarizes the historical evolution of nature conservation systems and strategies in the world with the related international legislative aspects as well. As it stated in this paper, USA and Europa have a well known history on nature conservation and show great concern in respect to participating to the international convention and arrangements.

    Due to the advantages that serious simulation game offered, many areas of studies, including energy, have used serious simulation games as their instruments. However, serious simulation games in the field of energy transition still have few attentions. In this study, serious simulation game is developed and tested as the activity of public education about energy transition which is a conversion from oil to natural gas program. The aim of the game development is to create understanding and awareness about the importance of energy transition for society in accelerating the process of energy transition in Indonesia since 1987 the energy transition program has not achieved the conversion target yet due to the lack of education about energy transition for society. Developed as a digital serious simulation game following the framework of integrated game design, the Transergy game has been tested to 15 users and then analysed. The result of verification and validation of the game shows that Transergy gives significance to the users for understanding and triggering the needs of oil to natural gas conversion.

  14. Extraterritorial hunting expeditions to intense fire scars by feral cats

    Science.gov (United States)

    2016-03-01

    Feral cats are normally territorial in Australia’s tropical savannahs, and hunt intensively with home-ranges only two to three kilometres across. Here we report that they also undertake expeditions of up to 12.5 km from their home ranges to hunt for short periods over recently burned areas. Cats are especially likely to travel to areas burned at high intensity, probably in response to vulnerability of prey soon after such fires. The movements of journeying cats are highly directed to specific destinations. We argue that the effect of this behaviour is to increase the aggregate impact of cats on vulnerable prey. This has profound implications for conservation, considering the ubiquity of feral cats and global trends of intensified fire regimes.

    Martínez, María; Rodríguez-Vigal, Carlos; Jones, Owen R; Coulson, Tim; Miguel, Alfonso San

    2005-01-01

    Much insight can be derived from records of shot animals. Most researchers using such data assume that their data represents a random sample of a particular demographic class. However, hunters typically select a non-random subset of the population and hunting is, therefore, not a random process. Here, with red deer (Cervus elaphus) hunting data from a ranch in Toledo, Spain, we demonstrate that data collection methods have a significant influence upon the apparent relationship between age and weight. We argue that a failure to correct for such methodological bias may have significant consequences for the interpretation of analyses involving weight or correlated traits such as breeding success, and urge researchers to explore methods to identify and correct for such bias in their data.

    Enhanced MRI was performed in 14 patients with Ramsay-Hunt,s syndrome to investigate the pathogenesis of this syndrome. All MRI studies were performed on a 0.5T superconductivity MRI system using a head coil with Gd-DTPA. Enhancement was observed in the areas of the distal internal auditory canal and labyrinthine segment in many patients, and was especially prominent in patients suffering from vertigo, tinnitus, and hearing loss. In some patients it involved not only the facial nerve of the internal auditory canal but also the cochlear nerve and vestibular nerves. Since histological changes of the facial nerve in patients with Ramsay-Hunt's syndrome are assumed to occur in the distal internal auditory canal and labyrinthine segment, which is more proximal than the geniculate ganglion, and the possibility is suggested that inflammation may be spread to the vestibular and cochlear nerve via the internal auditory canal.

    The current census of the most massive black holes in the local universe turns up an odd variety of galaxy hosts: central galaxies in rich clusters, second- or lower-ranked cluster members, and compact relics from the early universe. More extensive campaigns are required to explore the number density and environmental distribution of these monsters. Over the past three years we have collected a large set of stellar kinematic data with sufficient resolution to detect the gravitational signatures of supermassive black holes with MBH > 109 MSun. This Black Hole Safari targets enormous galaxies at the centers of nearby galaxy clusters, as well as their similarly luminous counterparts in weaker galaxy groups. To date we have observed more than 30 early-type galaxies with integral-field spectrographs on the Keck, Gemini North, and Gemini South telescopes. Here I present preliminary stellar kinematics from 10 objects.

Although spontaneous remission may occur, even corticosteroid therapy has a very satisfactory effect. However, relapse can occur after remission. We report a case of granulomatous Tolosa-Hunt syndrome in women aged 47 years who suffer from recurrent Tolosa-Hunt syndrome attacks for 4 years on his left eye, there was a significant recovery after receiving steroid therapy. Case:  We report A 47 years old with recurrent pain in the left eye since 4 years, pain episode duration of 1-2 weeks, accompanied by double vision when having long or short distance viewing, and when climbing stairs. The patient left eye was protruded with blurred vision and difficulty in distinguishing green color. Left eye examination vision 1/300, green color discromatopsia, normal funduscopic, ptosis, with paresis eye movement toward the superior, inferior, nasal and temporal. C-reactive protein and erythrocyte sedimentation rate were slightly elevated. ANA test was positive. In visual evoked potential, it showed latency elongation of the left face. Head MRI with contrast showed a isointense protrusion on the left cavernous sinus in axial cuts in T1 and T2. Head MRI T1 with contrast on coronal, axial cuts showed the appearance of convex lesions around the left cavernous sinus that enhanced with contrast. Conclusions: The result was clinically and radiographically diagnosed as Tolosa-Hunt Syndrome (THS. Therefore, 10 mg dexamethasone therapy, 4 times a day for 3 days was lowered to three times on day 4, 2 times on the fifth day and one time at day 6. The patient showed clinical improvement. The patient continued 48 mg oral methylprednisolone therapy up to 3 weeks which then gradually decreased and planned head MRI 3 months later.

    Today there is a great deal of interest in and a lot of hype about using video games in schools. Video games are a new silver bullet. Games can create good learning because they teach in powerful ways. The theory behind game-based learning is not really new, but a traditional and well-tested approach to deep and effective learning, often…

    This paper proposes a new class of potential games, the nested potential games, which generalize the potential games defined in Monderer and Shapley (1996), as well as the pseudo-potential games defined in Dubey et al. (2006). We show that each maximizer of a nested potential is a Nash equilibrium.

    For matrix games we study how small nonzero probability must be used in optimal strategies. We show that for image win–lose–draw games (i.e. image matrix games) nonzero probabilities smaller than image are never needed. We also construct an explicit image win–lose game such that the unique optimal...

    Concentrations of 26 elements (B, Na, Mg, P, S, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Mo, Cd, Sb, Ba, Hg, Pb, U) in wild game meat from Austria were analysed using an inductively coupled plasma mass spectrometer. All investigated animals were culled during the hunting season 2012/2013, including 10 chamois (Rupicapra rupicapra), 9 hare (Lepus europaeus), 10 pheasant (Phasianus colchicus), 10 red deer (Cervus elaphus), 12 roe deer (Capreolus capreolus) and 10 wild boar (Sus scrofa). In 19 out of 61 meat samples lead concentrations were higher than 0.1 mg/kg, the maximum limit in meat as set by the European Commission (Regulation EC No 1881/2006), which is most likely caused by ammunition residues. Especially, pellet shot animals and chamois show a high risk for lead contamination. Despite ammunition residues all investigated muscle samples show no further health risk with respect to metal contamination.

    The selection of an ambush-cum-foraging site and proper prey are indispensable for maintaining an adequate energy intake by sit-and-wait predators to optimize survival and future fitness. This is important for snakes, where an ambush site has suitable ambience. We studied the foraging strategy of the Palestine Saw-scaled Viper (Echis coloratus) at an avian migratory stopover site. Following initial observations, we hypothesized that vipers are able to discern the body mass of a perched bird and hunt accordingly. We implemented an experiment where vipers chose between four groups of migratory Blackcaps with different body mass. Prey choice by vipers of both age classes was not random and adults focused on Blackcaps with the lightest body mass. Juveniles displayed a variability of prey choice but selected mainly birds from the lightest categories. We concluded that Saw-scaled Vipers hunt prey based on thermal cues; juveniles practice on different prey groups prior to perfecting their foraging techniques i.e., hunting is a learned process; and that they prefer birds with the lowest body mass. The last because Blackcaps, when on migration, save energy by entering a state of deep torpor in which they sacrifice their vigilance capabilities. Copyright © 2015 Elsevier B.V.

    Full Text Available Introduction. Ramsay Hunt syndrome is a rare disease characterized by complications of herpes zoster oticus. This syndrome is defined by characteristic skin lesions with paresis of the facial and/or vestibulocochlear nerve. Objective. To present a case of a 14-year-old child with Ramsay Hunt syndrome. Case report . A 14-year-old patient was admitted to the Department of Dermatology due to vesicular lesions in the left auricular region. On medical examination, insufficiency of the left eyelid, asymmetry of the facial lines, drooping of the left corner of the mouth, and smoothing of the forehead were observed. According to the House-Brackmann scale, the patient had paresis (grade IV of the facial nerve. The patient was treated with intravenous acyclovir, antibiotics and anti-inflammatory drugs. Supplementation with vitamin B and rehabilitation procedures were also introduced. Conclusions . Ramsay Hunt syndrome is very rare in the pediatric population. It requires interdisciplinary cooperation between doctors. The presented case confirms the validity of therapy with acyclovir and prednisone and rehabilitation.

    The game statistics for the island of Olkiluoto were updated in April 2009, and compared with earlier studies. Population size estimates are based on interviews of local hunters, and other available material. Conclusions of changes in game populations are based on rough estimates primarily from interviews, only in Elk and Deer also on inventories. Elk population is still slightly decreasing. The growth of the White-tailed Deer population is slowing down. The changes in the Roe Deer population are not precisely known, but it is seemingly varying to some extent in different years. The populations of small predators (American Mink, Raccoon Dog and Red Fox) are still strong in Olkiluoto, partly because of very dense population of voles during the hunting season. The Raccoon Dog population has been diminished due to shooting several individuals during the Elk and Deer hunting. The Red Fox population is obviously increasing. The Mountain Hare population is strong and it increased in 2008. However, the Brown Hare population is apparently decreasing, probably due to kills by mammalian predators, eagles and traffic. Currently, other game animals (e.g. waterfowl) are hardly ever hunted. (orig.)

  19. Games of life and death: antibiotic resistance and production through the lens of evolutionary game theory.

    In this review, we demonstrate how game theory can be a useful first step in modeling and understanding interactions among bacteria that produce and resist antibiotics. We introduce the basic features of evolutionary game theory and explore model microbial systems that correspond to some classical games. Each game discussed defines a different category of social interaction with different resulting population dynamics (exclusion, coexistence, bistability, cycling). We then explore how the framework can be extended to incorporate some of the complexity of natural microbial communities. Overall, the game theoretical perspective helps to guide our expectations about the evolution of some forms of antibiotic resistance and production because it makes clear the precise nature of social interaction in this context.

  20. TAG Oil hunting elephants in New Zealand

    Calgary-based TAG Oil is an exploration company that manages 4.1 million acres of major producing oil and gas fields in New Zealand. The enormous Maui field, with 4 tcf of natural gas in place, has dominated the gas market in New Zealand by meeting nearly 90 per cent of the country's energy demand at costs much lower than world prices. However, the maturing field is in decline and will cease production by 2008. New gas field discoveries will only meet 60 per cent of the country's energy requirements for 5 additional years. Unless new large reserves of gas are discovered, the supply and demand situation will get worse. Lead time to place new production on-stream requires 5 to 10 years, which creates a large supply gap over the next decade. Public resistance to coal-fired power plants, new hydroelectric dams and nuclear power has left the country with no viable alternative to natural gas. TAG Oil has taken this unique opportunity to create value when gas demand is at its maximum and energy alternatives are at a minimum. This paper presented 8 reasons why New Zealand is a good place for petroleum investment. Most exploration has occurred in the Taranaki Basin, where only 130 exploration wells have been drilled. The rest of the sedimentary basins are essentially unexplored, although many exhibit oil seeps and have hydrocarbon potential. In 1998, an onshore gas discovery was made on the East Coast Basin. Sub-commercial discoveries have also been made in the offshore Canterbury and Great South basins. TAG Oil is focusing on shallow oil and gas pools in the Miocene reservoirs at Taranaki, as well as on deeper gas prospects in Tariki and Kapuni Sands. One of the challenges was a shortage of drilling rigs, so TAG is having a rig built in Calgary and shipped south. 2 figs
