    Horn, Scott; Hanula, James, L.


    Abstract This study determined if short-term removal of coarse woody debris would reduce prey available to red-cockaded woodpeckers (Picoides borealis Vieillot) and other bark-foraging birds at the Savannah River Site in Aiken and Barnwell counties, SC. All coarse woody debris was removed from four 9-ha plots of mature loblolly pine (Pinus taeda L.) in 1997 and again in 1998. We sampled arthropods in coarse woody debris removal and control stands using crawl traps that captured arthropods crawling up tree boles, burlap bands wrapped around trees, and cardboard panels placed on the ground. We captured 27 orders and 172 families of arthropods in crawl traps whereas 20 arthropod orders were observed under burlap bands and cardboard panels. The most abundant insects collected from crawl traps were aphids (Homoptera: Aphididae) and ants (Hymenoptera: Forrnicidae). The greatest biomass was in the wood cockroaches (Blattaria: Blattellidae), caterpillars (Lepidoptera) in the Family Noctuidae, and adult weevils (Coleoptera: Curculionidae). The most common group observed underneath cardboard panels was lsoptera (termites), and the most common taxon under burlap bands was wood cockroaches. Overall, arthropod abundance and biomass captured in crawl traps was similar in control and removal plots. In contrast, we observed more arthropods under burlap bands (mean & SE; 3,021.5 k 348.6, P= 0.03) and cardboard panels (3,537.25 k 432.4, P= 0.04) in plots with coarse woody debris compared with burlap bands (2325 + 171.3) and cardboard panels (2439.75 + 288.9) in plots where coarse woody debris was removed. Regression analyses showed that abundance beneath cardboard panels was positively correlated with abundance beneath burlap bands demonstrating the link between abundance on the ground with that on trees. Our results demonstrate that short-term removal of coarse woody debris from pine forests reduced overall arthropod availability to bark-foraging birds.

  5. On the pleasantness of a haptic stimulation: how different textures can be recognized through heart rate variability nonlinear analysis. (United States)

    Nardelli, Mimma; Greco, Alberto; Bianchi, Matteo; Scilingo, Enzo Pasquale; Valenza, Gaetano


    The hedonic attributes of cutaneous elicitation play a crucial role in everyday life, influencing our behavior and psychophysical state. However, the correlation between such a hedonic aspect of touch and the Autonomic Nervous System (ANS)-related physiological response, which is intimately connected to emotions, still needs to be deeply investigated. This study reports on caress-like stimuli conveyed to the forearm of 32 healthy subjects through different fabrics actuated by a haptic device, which can control both the strength (i.e. the normal force exerted by the fabric) and the velocity of the elicitation. The mimicked caresses were elicited with a fixed force of 6 N, two levels of velocity of 9.4 mm/sec and 65 mm/sec, and four different fabrics with different textures: burlap, hemp, velvet and silk. Participants were asked to score the caress-like stimuli in terms of arousal and valence through a self-assessment questionnaire. Heartbeat data related to the perceived most pleasant (silk) and unpleasant (burlap) fabrics were used as an input to an automatic pattern recognition procedure. Accordingly, considering gender differences, support vector machines using features extracted from linear and nonlinear heartbeat dynamics showed a recognition accuracy of 84.38% (men) and 78.13% (women) while discerning between burlap and silk elicitations at the higher velocity. Results suggest that the fabrics used for the caress-like stimulation significantly affect the nonlinear cardiovascular dynamics, also showing differences according to gender.

    Full Text Available Anthropogenic legacy effects often occur as a consequence of land use change or land management and can leave behind long-lasting changes to ecosystem structure and function. This legacy is described as a memory in the form of ecological structure or ecological interactions that remains at a location from a previous condition. We examined how forested floodplain restoration strategy, based on planting intensity, influenced wetland community structure and soil chemical and physical factors after 15 years. The site was divided into 15 strips, and strips were assigned to one of five restoration treatments: plantings of acorns, 2-year-old seedlings, 5-ft bareroot trees, balled and burlapped trees, and natural seed bank regeneration. Our community composition survey revealed that plots planted with bareroot or balled and burlapped trees developed closed tree canopies with little herbaceous understory, while acorn plantings and natural colonization plots developed into dense stands of the invasive species reed canary grass (RCG; 'Phalaris arundinacea'. Restoration strategy influenced bacterial community composition but to a lesser degree compared to the plant community response, and riverine hydrology and restoration strategy influenced wetland soil conditions. Soil ammonium concentrations and pH were similar across all wetland restoration treatments, while total organic carbon was highest in forest and RCG-dominated plots compared to mixed patches of trees and open areas. The differences in restoration strategy and associated economic investment resulted in ecological tradeoffs. The upfront investment in larger, more mature trees (i.e., bareroot, balled and burlapped led to floodplain forested communities, while cheaper, more passive planting strategies (i.e., seedlings, seedbank, or acorns resulted in dense stands of invasive RCG, despite the similar floodplain hydrology across all sites. Therefore, recovery of multiple ecosystem services that

    Adnan; Parung, H.; Tjaronge, M. W.; Djamaluddin, R.


    Many cement factories have been incorporated fly ash with clinker cement to produce blended cement. PCC is a type of blended cement incorporated fly ash that produced in Indonesia cement factories. To promote the sustainable development in the remote islands this present paper attempted to study the suitability of sea water, marine sand that available abundantly surround the remote island with Portland Composite Cement (PCC) and crushed river stone to produce concrete. Slump test was conducted to evaluate the workability of fresh concrete and also compressive strength with stress-strain relationship was carried out to evaluate the hardened concrete that cured with two curing condition (e.g. sea water curing, and tap water-wet burlap curing). Test result indicated that fresh concrete had proper workability and all hardened specimens appeared a good compaction result. Compressive strength of specimens cured which sea water was higher than the specimens which cured by tap water-wet burlap where stress-strain behavior of specimens made with sea water, marine sand, and PCC had similar behavior with specimens which made with PCC and tap water.

  9. Comparing fungal band formulations for Asian longhorned beetle biological control. (United States)

    Ugine, Todd A; Jenkins, Nina E; Gardescu, Sana; Hajek, Ann E


    Experiments were conducted with the fungal entomopathogen Metarhizium brunneum to determine the feasibility of using agar-based fungal bands versus two new types of oil-formulated fungal bands for Asian longhorned beetle management. We investigated conidial retention and survival on three types of bands attached to trees in New York and Pennsylvania: standard polyester fiber agar-based bands containing fungal cultures, and two types of bands made by soaking either polyester fiber or jute burlap with oil-conidia suspensions. Fungal band formulation did not affect the number or viability of conidia on bands over the 2-month test period, although percentage conidial viability decreased significantly with time for all band types. In a laboratory experiment testing the effect of the three band formulations on conidial acquisition and beetle survival, traditional agar-based fungal bands delivered the most conidia to adult beetles and killed higher percentages of beetles significantly faster (median survival time of 27d) than the two oil-formulated materials (36-37d). We also tested the effect of band formulation on conidial acquisition by adult beetles kept individually in cages with a single band for 24h, and significantly more conidia (3-7times) were acquired by beetles from agar-based bands compared to the two oil formulations.

    Ryon, M. G.; Jett, R. T.; McCracken, M. K.; Morris, G. W.; Roy, W. K.; Fortner, A. M.; Goins, K. N.; Riazi, A. S.


    A technique for increasing the establishment rate of American lotus (Nelumbo lutea) and simplifying planting was developed as part of a pond remediation project. Lotus propagation techniques typically require scarification of the seed, germination in heated water, and planting in nursery containers. Then mature (~ 1 yr) nursery-grown stock is transferred to planting site or scarified seed are broadcast applied. Mature plants should grow more quickly, but can be sensitive to handling, require more time to plant, and cost more. Scarified seeds are easier to plant and inexpensive, but have a lag time in growth, can fail to germinate, and can be difficult to site precisely. We developed an intermediate technique using small burlap bags that makes planting easier, provides greater germination success, and avoids lag time in growth. Data on survival and growth from experiments using mature stock, scarified seeds, and bag lotus demonstrate that bag lotus grow rapidly in a variety of conditions, have a high survival rate, can be processed and planted easily and quickly, and are very suitable for a variety of remediation projects

    Fabiano de Oliveira Fortes


    Full Text Available O trabalho foi realizado na Floresta Ombrófila Mista, de grande diversidade tipológica, em São Francisco de Paula, Rio Grande do Sul. O objetivo foi estimar a serapilheira acumulada, coletada com diferentes tamanhos de molduras e determinar a intensidade amostral em cada estação sazonal. Foram obtidas 15 amostras aleatórias por hectare para cada moldura em cada estação sazonal. A serapilheira foi separada nos estratos folhas, cascas, galhos e miscelâneas, foi secada e pesada e os dados foram expressos em t ha-1. Procedeu-se uma análise de variância conjunta com as fontes de variação "moldura, estação, interação e erro". Foi estimada a média, a variância e o coeficiente de variação e foi realizado o teste de homogeneidade das variâncias entre as estações e entre as molduras. Admitindo-se um erro de amostragem máximo de 10, 15, 20 e 25% da média estimada, calculou-se a intensidade de amostragem, por hectare, para população infinita. A interação entre moldura e estação não foi significativa para a serapilheira e para os estratos e nem houve diferenças significativas entre as molduras. As variâncias da serapilheira foram homogêneas entre as molduras nas quatro estações e foram heterogêneas entre as estações nas quatro molduras. É preferido usar a moldura muito pequena (0,25m², com 27 unidades de amostra no inverno, 25 na primavera, 33 no outono e 15 no verão para uma precisão de 15% de diferença entre as médias.The present research was accomplished in the Forest Mixed Ombrófila of São Francisco de Paula - FLONA, being this representative of great diversity in the State of Rio Grande do Sul. The objective was to esteem the accumulated burlap collected with four different collecting frames and the amostral intensity in each seasonal station. 15 random samples were collected for each frame by hectare in each seasonal station being separated in the stratus leaves, peels, branches and miscellany.

  12. Green technologies in natural and synthetic surfaces use for dumps reclamation (United States)

    Klimkina, Iryna; Fedotov, Viacheslav; Heilmeier, Hermann


    Last 50 years coal dumps reclamation in Ukraine was based on two- or three-layer models. These models use a fertile substratum underneath a black soil (chernozem) layer 0.5 m thick (Model 1) or 0.70-1 m thick (Model 2). Model 3 has 3 layers. The deepest layer is a substrate which is phytotoxic or unfavourable for crop growth (coal-bearing substrates with a high content of pyrite, saline substrates). The second layers acts as a protective shield and consist of loess (0.5 m). The third is the layer of fertile chernozem (0.3-0.8 m). However, due to the situation of a shortage of fertile soils, a lack of nutrient elements in the waste rock, and a moisture deficit with strong rock acidification, it is considered important to develop new non-traditional reclamation methods based on the geo-synthetic materials used in conjunction with sowing lawn grasses or grass seeds inside. The geogrids and biogeotextiles made from natural materials such as hemp, flax, jute, coconut and other plant biopolymer fibers are recommended for bioremediation. The biodegradable carcass of reclamation covering materials stabilises the slopes, effectively restraints the soil particles from leaching and blowing, and prevents wash-out of the plant seeds, as well as protecting them from being eaten by animals. The research object of the presented work was the coal dumps of sulfide rocks in Western Donbass (Ukraine). These rocks are characterized by low level of the maximum hygroscopic moisture (4.3%) and moisture content not available for plant growth (5-6%). Also the rock has an average level of salinity, mainly of the sulphate type. The main goal of the study was to justify the use of some non-traditional materials such as burlap (jute cloth), agricultural fibers (light non-woven material from polypropylene fiber of spun-bond type) and a padding of polyester in the capacity of a geosynthetic substrate as a basis for the mixed grass crop that enable a reduction in the bioremediation costs (in

  14. Evaluation of meso fauna soil as bio-indicator of environmental quality in forests remnants in the city of São Paulo - Preliminary Results (United States)

    Patucci, Natalia; Oliveira, Deborah


    Soil quality is particularly through composition and structure, as well as by, measured by physical and chemical indicators, as well as by living organisms contained therein, which play the most varied ecological functions. The abundance and diversity of soil macrofauna in ecosystems can be affected by many factors, precisely because these organisms are sensitive to environmental changes, whether induced or natural. Thus, soil populations can be measured as bioindicators, since changes in the community may indicate possible changes in soil functioning. This research aims to survey the biodiversity of meso soil fauna environments with remaining Atlantic Forest (Fontes do Ipiranga park, Cantareira park and Jaraguá park) in order to detect specific features and significant changes in ecological function performed by these soil communities. The project aims to develop an overview of multivariate understanding about soil, especially the relation of variation of pedofauna with the occurring physical and chemical modifications in order to be able to prove the adaptation of soil fauna with variations in temperature, humidity, sunshine, influence of vegetation, soil genesis and topographic gradient. According to Lavelle & Spain (2001), the temperature and humidity are the main factors that activate the metabolic regulation in subjects of soil fauna, which ultimately determine their spatial distribution, periods of increased activity, peculiarities and significant changes, the function of these communities in the substrate. Two combining sampling will be performed, one in the rainy season, in January, and another in the dry season, in July, with the purpose of measuring the diversity of populations according to seasonality. Invertebrates associated soil interface - burlap (Moreira et al, 2010) will be caught by pitfall traps, which will be distributed in three installments by park, containing a sampling gride with nine equidistant points 30 meters of each other.
