Nuestros resultados muestran que T. brasiliensis es un murciélago más robusto, de mayor envergadura, pero con un área alar similar a la de M. chiloensis. Esta última especie tiene una menor variabilidad en su masa y área cortical del húmero, que probablemente se encuentre relacionada con restricciones mecánicas y energéticas impuestas por su diseño. Descontando el efecto de la masa se detectaron diferencias en el diámetro externo y diámetro medular del húmero con una similar área cortical. El húmero de T. brasiliensis es un hueso de similar longitud, más ancho y con un menor grosor cortical que el de M. chiloensis, lo que está relacionado con una mayor resistencia a las fuerzas de flexión y torsión. Las características alares son consistentes con los modos de vida de cada murciélago: vuelos lentos, cortos y maniobrables en zonas arbustivas de M. chiloensis y vuelo veloz y de grandes distancias en espacios abiertos de T. brasiliensisWing morphology is related by one hand to biomechanical properties and energetics of flying, and on the other hand to ecological and behavioral aspects of flying, such as flight pattern, foraging behavior, habitat selection and size of prey.

Full Text Available Currently twelve species of Myotis Kaup, 1829 (Vespertilionidae: Myotinae are recognized from South America, with several other named taxa regarded as synonyms, among them Myotis punensis J.A. Allen, 1914. This name was first regarded as a junior synonym of Myotis albescens (É. Geoffroy, 1806 and subsequently of Myotis nigricans (Schinz, 1821. To address the taxonomic status of the holotype of M. punensis, we compared it to all South American species in the genus. The fringe of hairs on the trailing edge of the uropatagium, the fur color, and external and skull dimensions all suggest M. punensis should be treated as a junior synonym of M. albescens

Complete mitochondria genome sequences of myotis petax (Chiroptera; Microchiroptera; Vespertilionidae) were first identified in the present study. The sequences were obtained from the four individuals and composition of nucleotide AT and GC was about 64.58% and 35.42%, respectively. The lengths of mitogenomes were ranged from 17 296 to 17 299 bp. Total 51 variable sites were observed in the four mitogenomes and 38 sites were singleton polymorphic sites. Phylogenic study revealed that the species would have relatively closed evolutionary distance with m. macrodactylus rather than other species in the genus, myotis. Present study will provide important genomic materials supporting confirmation of taxon of species called bats, which is included in one of the largest orders among the mammals. PMID:26332748

We sequenced and characterized the complete mitogenome of Hypsugo alaschanicus (Vespertilionidae) to provide more data for comparative mitogenomics of the genus Hypsugo. The mitogenome of H. alaschanicus is a circular molecule of 17,300 bp, consisting of a control region and a typically conserved set of 37 vertebrate genes containing 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes (12S rRNA and 16S rRNA). The mitogenome of H. alaschanicus is AT-biased, with a nucleotide composition of 34.1 A, 30.9 T, 22.4 C, and 12.6% G. In the 13 mitochondrial PCGs of H. alaschanicus, the start codon ATG is used in all PCGs, except Nd2 and Nd3 (which use ATT), and Nd5 (which uses ATA). Eight PCGs (Nd1, Cox1, Cox2, Atp8, Atp6, Nd4L, Nd5, and Nd6) use TAA as the stop codon, while the stop codon AGA occurs only in Cytb. Incomplete stop codons (T--) are used in the other four PCGs (Cox3, Nd2, Nd3, and Nd4). These findings contribute to our understanding of the nucleotide composition and molecular evolution of the mitogenomes of the genus Hypsugo, and provide more data for comparative mitogenomics and higher phylogeny in the family Vespertilionidae.

Full Text Available Abstract Between 1994 and 2008, we studied the structure of harems in Nyctalus leisleri and factors that determine their size by monitoring 90 bat-boxes placed in a beech forest in the natural reserve Pian degli Ontani (Tuscany, northern Italy. The number of females in the harem positively correlated with the number of males defending a harem. The number of males in the mating area did not significantly influence harem size, whilst we found a significant correlation between the variance in harem size and mean harem size. This may be explained by the existence of an uneven aggregation favouring few males. A strong relation was found between males’ age (estimated by teeth wear and mean harem size.

Il numero di maschi presenti non influenza la dimensione media dell'harem mentre una significativa correlazione positiva è stata evidenziata tra il valore della varianza delle dimensioni dell'harem e la sua dimensione media. Tale relazione suggerisce che le femmine tendono ad aggregarsi, favorendo i maschi più competitivi.

The mitochondrial genome of Nyctalus noctula is a circular molecule of 17,478 bp in length, containing 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNAs and a D-loop region. The overall A + T content of the H-strand is 61.4% (A 32.0%, T 29.4%, C 24.1% and G 14.5%). Among the 13 protein-coding genes, most of them begin with ATG as the start codon except for ND5 with ATA and ND2 and ND3 with ATT. ND1 and ND2 genes terminate with TAG as the stop codon, Cyt b ends with AGA, COIII, ND3 and ND4 genes end with an incomplete stop codon (T- -) and the other protein-coding genes end with TAA. In Bayesian inference (BI) and Maximum likelihood (ML) trees, we found that N. noctula is a sister clade to Pipistrellus abramus, and (Nyctalus + Pipistrellus) is a sister clade to (Chalinolobus + (Eptesicus + Vespertilio)) (1.00 in BI and 100% in ML).

In July 2002, several bats of the genus Plecotus (Geoffroy, 1818) were captured at two localities of ‘Ordesa y Monte Perdido’ National Park (Central Pyrenees, Spain). They showed external characters that appeared intermediate between those of P. auritus and P. austriacus. Morphometric and genetic analysis have revealed that these long-eared bats should be ascribed to the recently recognized species P. macrobullaris. This study extends the distribution of this new species, whose western ...

Bats are mammals in the order Chiroptera. Although many extensive morphologic and molecular genetics analyses have been attempted, phylogenetic relationships of bats has not been completely resolved. The paraphyly of microbats is of particular controversy that needs to be confirmed. In this study, we attempted to use the nucleotide sequence of transthyretin (TTR) intron 1 to resolve the relationship among bats. To explore its utility, the complete sequences of TTR gene and intron 1 region of bats in Vespertilionidae: genus Eptesicus (Eptesicus fuscus) and genus Myotis (Myotis brandtii, Myotis davidii, and Myotis lucifugus), and Pteropodidae (Pteropus alecto and Pteropus vampyrus) were extracted from the retrieved sequences, whereas those of Rhinoluphus affinis and Scotophilus kuhlii were amplified and sequenced. The derived overall amino sequences of bat TTRs were found to be very similar to those in other eutherians but differed from those in other classes of vertebrates. However, missing of amino acids from N-terminal or C-terminal region was observed. The phylogenetic analysis of amino acid sequences suggested bat and other eutherian TTRs lineal descent from a single most recent common ancestor which differed from those of non-placental mammals and the other classes of vertebrates. The splicing of bat TTR precursor mRNAs was similar to those of other eutherian but different from those of marsupial, bird, reptile and amphibian. Based on TTR intron 1 sequence, the inferred evolutionary relationship within Chiroptera revealed more closely relatedness of R. affinis to megabats than to microbats. Accordingly, the paraphyly of microbats was suggested. PMID:26681450

The aim of the study is to use cluster analysis on morphometric parameters within the genus Kerivoula to produce a dendrogram and to determine the suitability of this method to describe the relationship among species within this genus. A total of 15 adult male individuals from genus Kerivoula taken from sampling trips around Borneo and specimens kept at the zoological museum of Universiti Malaysia Sarawak were examined. A total of 27 characters using dental, skull and external body measurements were recorded. Clustering analysis illustrated the grouping and morphometric relationships between the species of this genus. It has clearly separated each species from each other despite the overlapping of measurements of some species within the genus. Cluster analysis provides an alternative approach to make a preliminary identification of a species.

Southeast Asia is a region of high biodiversity, containing species of plants and animals that are yet to be discovered. In this region, bats of the subfamily Kerivoulinae are widespread and diverse with six species recorded in Vietnam. However, the taxonomy of the Kerivoulinae in Asia is complicated. In our study, we used diagnostic characters and multivariate analysis to determine morphological differences between the genera Kerivoula and Phoniscus. We showed that the two genera are distinguishable by the size of second upper incisors, the shape of skull, nasal sinus, canines, second upper and lower premolars. In addition, the two genera can be osteometrically separated by measurements of the braincase height, interorbital width and shape of anterior palatal emargination. Our data clearly revealed the morphological variations in the skull shape of Kerivoula hardwickii in Vietnam. This suggests a possible separation into three morphotypes, representing cryptic species supported by statistical differences with wide variation in skull shape, size and teeth. These results demonstrated Kerivoula hardwickii can be separated three subspecies, and the result will serve as the basis for the future assessment and classification of this group in Southeast Asia.

We documented nightly movements of Hawaiian hoary bats (Lasiurus cinereus semotus) on the island of Hawai’i. Based on data from 28 radiotagged individuals mean foraging range (FR) was 230.7±72.3 ha, core-use area (CUA) was 25.5±6.9 ha (or 11.1% of mean FR), and the mean long axis (LAX) across the FR was 3,390.8±754.3 m. There was almost no overlap in CUAs among 4 adult males having overlapping foraging areas and tracked simultaneously or within a 90-day window of each other. CUAs of subadults partially overlapped with multiple adult males or with one other subadult. High variance in FRs, cores use areas, and LAX across the FR perhaps reflect localized stochastic variables such as weather, habitat, and food resources. Hawaiian hoary bats use moderately large FRs among insectivorous bats studied with comparable methodologies; however, foraging activity indicated by documentation of acoustic feeding buzzes is concentrated within one or a few disjunct areas cumulatively forming the 50% fixed kernel of CUA. The concentration of feeding activity, low values of individual overlap, and agonistic chasing behavior within CUAs all demonstrate a structured use of individual space by Hawaiian hoary bats.

Full Text Available BACKGROUND: Cryptic morphological variation in the Chiropteran genus Myotis limits the understanding of species boundaries and species richness within the genus. Several authors have suggested that it is likely there are unrecognized species-level lineages of Myotis in the Neotropics. This study provides an assessment of the diversity in New World Myotis by analyzing cytochrome-b gene variation from an expansive sample ranging throughout North, Central, and South America. We provide baseline genetic data for researchers investigating phylogeographic and phylogenetic patterns of Myotis in these regions, with an emphasis on South America. METHODOLOGY AND PRINCIPAL FINDINGS: Cytochrome-b sequences were generated and phylogenetically analyzed from 215 specimens, providing DNA sequence data for the most species of New World Myotis to date. Based on genetic data in our sample, and on comparisons with available DNA sequence data from GenBank, we estimate the number of species-level genetic lineages in South America alone to be at least 18, rather than the 15 species currently recognized. CONCLUSIONS: Our findings provide evidence that the perception of lower species richness in South American Myotis is largely due to a combination of cryptic morphological variation and insufficient sampling coverage in genetic-based systematic studies. A more accurate assessment of the level of diversity and species richness in New World Myotis is not only helpful for delimiting species boundaries, but also for understanding evolutionary processes within this globally distributed bat genus.

The complete nucleotide sequence of the mitochondrial genome of the Asian particolored bat, Vespertilio sinensis, was determined. The genome organization, gene contents, and codon usage conformed to those of other bat mitochondrial genomes. The total length of the mitogenome of Vespertilio sinensis is 16,971 bp with a total base composition of 32.6% A, 29.6% T, 23.7% C and 14.0% G. The mitogenome consists of 13 protein-coding genes, 2 rRNA (12S and 16S RNA) genes, 22 tRNA genes and 1 control region. PMID:24660937
Full Text Available The activity time of the lesser bamboo bat, Tylonycteris pachypus (Temminck, 1840, was investigated at two observation locations in southern China: Longzhou and Guiping. Two bouts of activity (post dusk and predawn, with an intervening period of night roosting at diurnal roosts, were identified. The period of activity within each bout was usually less than 30 minutes. The activity periods of individuals belonging to the Longzhou population right after dusk and just before dawn lasted longer than those of the the Guiping population. We also found that the nocturnal emergence time of T. pachypus from the Longzhou population happened earlier than in the Guiping population. These findings indicate that the activity time of T. pachypus was quite short at night, and that different locations may affect the nocturnal activity rhythm of this species.

Bats are a unique but enigmatic group of mammals and have a world-wide distribution. The phylogenetic relationships of extant bats are far from being resolved. Here, we investigated the karyotypic relationships of representative species from four families of the order Chiroptera by comparative chromosome painting and banding. A complete set of painting probes derived from flow-sorted chromosomes of Myotis myotis (family Vespertilionidae) were hybridized onto metaphases of Cynopterus sphinx (2n = 34, family Pteropodidae), Rhinolophus sinicus (2n=36, family Rhinolophidae) and Aselliscus stoliczkanus (2n=30, family Hipposideridae) and delimited 27, 30 and 25 conserved chromosomal segments in the three genomes, respectively. The results substantiate that Robertsonian translocation is the main mode of chromosome evolution in the order Chiroptera, with extensive conservation of whole chromosomal arms. The use of M. myotis (2n=44) probes has enabled the integration of C. sphinx, R. sinicus and A. stoliczkanus chromosomes into the previously established comparative maps between human and Eonycteris spelaea (2n=36), Rhinolophus mehelyi (2n=58), Hipposideros larvatus (2n=32), and M. myotis. Our results provide the first cytogenetic signature rearrangement that supports the grouping of Pteropodidae and Rhinolophoidea in a common clade (i.e. Pteropodiformes or Yinpterochiroptera) and thus improve our understanding on the karyotypic relationships and genome phylogeny of these bat species.

Rhinolophus (Rhinolophidae) is the second most speciose genus in Chiroptera and has extensively diversified diploid chromosome numbers (from 2n = 28 to 62). In spite of many attempts to explore the karyotypic evolution of this genus, most studies have been based on conventional Giemsa staining rather than G-banding. Here we have made a whole set of chromosome-specific painting probes from flow-sorted chromosomes of Aselliscus stoliczkanus (Hipposideridae). These probes have been utilized to establish the first genome-wide homology maps among six Rhinolophus species with four different diploid chromosome numbers (2n = 36, 44, 58, and 62) and three species from other families: Rousettus leschenaulti (2n = 36, Pteropodidae), Hipposideros larvatus (2n = 32, Hipposideridae), and Myotis altarium (2n = 44, Vespertilionidae) by fluorescence in situ hybridization. To facilitate integration with published maps, human paints were also hybridized to A. stoliczkanus chromosomes. Our painting results substantiate the wide occurrence of whole-chromosome arm conservation in Rhinolophus bats and suggest that Robertsonian translocations of different combinations account for their karyotype differences. Parsimony analysis using chromosomal characters has provided some new insights into the Rhinolophus ancestral karyotype and phylogenetic relationships among these Rhinolophus species so far studied. In addition to Robertsonian translocations, our results suggest that whole-arm (reciprocal) translocations involving multiple non-homologous chromosomes as well could have been involved in the karyotypic evolution within Rhinolophus, in particular those bats with low and medium diploid numbers.

Previous genetic analyses have demonstrated that two phonic types of one of the most common European bats, the Common pipistrelle, belong to distinct species, although they are almost identical morphologically (45 kHz Pipistrellus pipistrellus and 55 kHz Pipistrellus pygmaeus). To reconstruct the history of the species complex and explain the codistribution of both forms in Europe and the Mediterranean, we performed phylogenetic analysis based on a 402-bp portion of the cytochrome b gene. Particular attention was paid to the eastern and southern parts of the range where no data were available. We found further distinctive allopatric haplotypes from Libya and Morocco. The difference of about 6-7% described in the Libyan population suggests the occurrence of a new species in the southern Mediterranean. The species status of Moroccan population is also discussed. The phylogeographic patterns obtained and analysis of fossil records support the hypothesis of expansion of both species into Europe from the Mediterranean region during the Holocene. The allopatric speciation model fits our data best. The paleobiographic scenario envisaged is corroborated also by molecular clock estimations and correlations with Late Neogene environmental changes in the Mediterranean region which ended with the Messinian salinity crisis.

To date, three species of the genus Glischropus are recognized from the Indomalayan zoogeographic region-G. bucephalus from the Indochinese subregion, G. tylopus from the Sundaic subregion (Peninsular Thailand and Malaysia, Borneo, Sumatra, Moluccas) and G. javanus, restricted to Java. The investigation of the holotype and three topotype specimens of G. batjanus supported the view that the name was previously correctly regarded as the junior subjective synonym of G. tylopus. During review of material recently collected in southwestern Sumatra, Indonesia, one specimen of a yet undescribed species of Thick-thumbed bat was identified. G. aquilus n. sp. markedly differs from its congeners by its dark brown pelage, nearly black ear and tragus, and in skull proportions. The phylogenetic analysis based on cytb sequences also supports the specific distinctness of G. aquilus n. sp. Its discovery brings the count to 88 species of bats known from Sumatra. PMID:26249952
Full Text Available Abstract Background Various mechanisms such as geographic barriers and glacial episodes have been proposed as determinants of intra-specific and inter-specific differentiation of populations, and the distribution of their genetic diversity. More recently, habitat and climate differences, and corresponding adaptations have been shown to be forces influencing the phylogeographic evolution of some vertebrates. In this study, we examined the contribution of these various factors on the genetic differentiation of the bent-winged bat, Miniopterus schreibersii, in southeastern Europe and Anatolia. Results and conclusion Our results showed differentiation in mitochondrial DNA coupled with weaker nuclear differentiation. We found evidence for restriction of lineages to geographical areas for hundreds of generations. The results showed that the most likely ancestral haplotype was restricted to the same geographic area (the Balkans for at least 6,000 years. We were able to delineate the migration routes during the population expansion process, which followed the coasts and the inland for different nested mitochondrial clades. Hence, we were able to describe a scenario showing how multiple biotic and abiotic events including glacial periods, climate and historical dispersal patterns complemented each other in causing regional and local differentiation within a species.
Full Text Available The barbastelle bat, Barbastella barbastellus (Schreber, 1774 is a medium-sized, tree-dwelling vespertilionid classified as ?Endangered? in Italy; in western Europe it may be one of the rarest bat species. B. barbastellus shows roosting preferences that should be regarded as a key point in conservation protocols. We examined roost selection in a breeding population of B. barbastellus from the Abruzzo Lazio and Molise National Park (central Italy at three levels: woodland structure and management type; tree characteristics; and cavity characteristics. In 2001-2002, we fitted 31 adult B. barbastellus (29 lactating females, one pregnant female and one male with 0.48g radio-tags and tracked them to their roost-trees. The bats were tracked for 4.5 ± 3.7 days (range: 0-12 days. We located 33 roosts used by 25 subjects (1.8±1.2 roosts/bat, range 1-5. The bats switched roosts frequently: 13 bats used more than one tree over the study period. A chi-square analysis showed that the roosts were not distributed at random across woodland categories: unmanaged woodland was positively selected, whereas shelterwood-harvested woodland was used in proportion to its availability, and ?pastures+scattered trees? was avoided. Twenty out of 33 roost trees were dead Fagus sylvatica trees; conversely, living F. sylvatica dominated in a tree sample obtained at random; dead trees were used more than expected (Χ² test, P <0.001. Overall, roost trees were significantly taller and had a larger diameter at breast?s height and more cavities than random trees; they also had a lower percent canopy closure than random trees. To highlight which variables were actually associated with selection, we devised a logistic regression model. The full model was significant (P <0.001; removal of tree type and tree height affected the model significantly, but the other variables did not produce detectable effects. The bats roosted under loose bark in 20 of 27 trees, i.e. more frequently than expected (Χ² test, P < 0.05. B. barbastellus preferred cavities at a greater height (median roost height = 10.1 m, n = 22; median random cavity height = 4.5 m, n = 30; Mann-Whitney test, P < 0.01. Most roosts faced south (63.6% south facing: 91-270 degrees; 36.4% north facing: 271-90 degrees, n = 22; Χ² test, P < 0.05. A logistic regression model including cavity type, height above ground and direction faced was significant (P <0.01 and all variables were important for selection. B. barbastellus is probably unable to find suitable roosting sites where intensive and non-selective logging is conducted: areas of ancient woodland should be protected to ensure optimal roosting conditions. In roosting areas, felling operations should be avoided as far as possible; in logged areas, selective timber harvesting protocols preserving dead trees and a significant fraction of mature trees should be adopted. We are indebted to the Nando Peretti Foundation and the Parco Nazionale d?Abruzzo Lazio e Molise for funding our work.

Full Text Available Myotis nigricans is a species of vespertilionid bat, whose males show two periods of total testicular regression within the same annual reproductive cycle in the northwest São Paulo State, Brazil. Studies have demonstrated that its epididymis has an elongation of the caudal portion, which stores spermatozoa during the period of testicular regression in July, but that they had no sperm during the regression in November. Thus, the aim of this study was to analyze the impact of the total testicular regression in the epididymal morphophysiology and patterns of its hormonal regulation. The results demonstrate a continuous activity of the epididymis from the Active to the Regressing periods; a morphofunctional regression of the epididymis in the Regressed period; and a slow recrudescence process. Thus, we concluded that the processes of total testicular regression and posterior recrudescence suffered by M. nigricans also impact the physiology of the epididymis, but with a delay in epididymal response. Epididymal physiology is regulated by testosterone and estrogen, through the production and secretion of testosterone by the testes, its conduction to the epididymis (mainly through luminal fluid, conversion of testosterone to dihydrotestosterone by the 5α-reductase enzyme (mainly in epithelial cells and to estrogen by aromatase; and through the activation/deactivation of the androgen receptor and estrogen receptor α in epithelial cells, which regulate the epithelial cell morphophysiology, prevents cell death and regulates their protein expression and secretion, which ensures the maturation and storage of the spermatozoa.
Full Text Available By combining cellulose acetate allozyme electrophoresis with a non-lethal sampling technique, it was possible to undertake a preliminary study of the population structure of Myotis punicus Felten, 1977 in the Maltese Islands. Since previous local ecological studies indicated declining numbers, it was considered important to undertake a combinatorial study including molecular genetic techniques. Twelve sites spread around the Maltese Islands were investigated and a total of 36 individuals found in four of these sites were sampled over a period of 6 months. The use of 4mm biopsy punches (a non-lethal method was adopted to obtain tissue for analysis. Morphometric data was also collected involving measurements of forearm length, ear length, tragus length, wing-span and weight. Comparison of average values for these measurements between the sexes (using chi-square at p = 0.05 gave an indication of sexual dimorphism, with females being the larger sex. A recapture rate of 19% was achieved in this study. Nei’s (1978 Genetic Identity (I showed values from 0.954 to 0.686, while Genetic Distance (D values ranged from 0 to 0.047. The results obtained in this study indicate that the population on the Maltese Islands is as yet a single panmictic unit, even though the overall FST value of 0.272 indicates that these sites are approaching the threshold beyond which there will be isolated mating systems.

We sequenced and characterized the complete mitogenome of the Nepalese whiskered bat Myotis muricola (Vespertilionidae) to provide more data for comparative mitogenomics and codon usage in the genus Myotis (Vespertilionidae). The mitogenome of M. muricola is a circular molecule of 17,224 bp, consisting of a control region and a conserved set of 37 genes containing 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes (12S rRNA and 16S rRNA). The mitogenome of M. muricola is AT-biased, with a nucleotide composition of 33.6% A, 29.7% T, 23.3% C, and 13.4% G. The total length of the 13 mitochondrial PCGs, excluding stop codons, is 11,376 bp, or 3792 amino acids. The relative synonymous codon usage (RSCU) of codons ending in A/T was generally higher than that for codons ending in G/C. The most frequently used codons are CTA(Leu) and CGA(Arg), with RSCU values greater than 2.0. The most rarely used codons, all terminating in G, are TCG(Ser), CCG(Pro), GCG(Ala), AAG(Lys), TGG(Try), CGG(Arg), and ACG(Thr), with RSCU values below 0.2. TCG(Ser) occurs only five times, and has the lowest RSCU value (0.091). These results are valuable for a better understanding of the molecular evolution of mitogenomes in the genus Myotis.

Zoonosis is the cause of the vast majority of emerging diseases. Bats that occupy the second place in the mammal class play an important role. Whether they belong to the microchiroptera suborder or to the megachiroptera suborder, bats on all five continents have been implicated in transmission of numerous pathogens including not only viruses such as Lyssavirus (e.g. rabies), Hepanivirus (e.g. Hendra and Nipah virus) and recently coronavirus (e.g. SARS-like coronavirus and Ebola virus) but also fungus such as histoplasmosis. By modifying environmental conditions and encroaching on their biotope, human intervention has probably contributed to the introduction of chiropteras into an epidemiologic chain in which they previously had no place, thus promoting the emergence of new pathogens.

Full Text Available A partir da experiência de representantes portugueses em Conselhos de Empresa Europeus (CEE, aborda‑se a avaliação que aqueles fazem do cumprimento dos dois princípios basilares da Directiva: a informação e a consulta. A este propósito, são tidas em conta duas dimensões da vida dos CEE: a dimensão funcional e a dimensão das possibilidades práticas. A primeira reporta-se ao modo como a informação e a consulta se encontram vertidas nos textos dos acordos que ditam o modus operandi dos CEE e ao modo como os representantes dos trabalhadores avaliam a informação que lhes é transmitida. A segunda dimensão encontra-se mais orientada para o princípio da consulta e para as possibilidades de os CEE condicionarem as decisões das multinacionais. Ainda que ambas as dimensões sejam olhadas como pouco entusiasmo pelos representantes portugueses, este texto, apoiando‑se no exemplo da GM-Europa, não deixa, todavia, de fazer referência ao papel que os CEE podem desempenhar na construção de uma identidade laboral transnacional.

The heterogeneity of formation of different areas in the wing membrane of Chiroptera and Dermoptera was established. The web between metacarpals and digits (chiropatagium) was formed by the mesenchyme which initially formed the forelimb rudiment. The plagiopatagium and propatagium were formed by proliferation of the trunk mesenchymal cells.

Environmental monitoring at wind turbine arrays is needed before, during and after project development. Pesca Environmental evaluates the impact of proposed wind turbine arrays on birds and chiroptera by examining their migration patterns through visual and auditory observations during the springtime reproductive and nesting season as well as in the autumn. In order to complete a feasibility study, spring migration patterns of birds and chiroptera must be documented and characterized. In addition to building an inventory of birds and chiroptera, Pesca examines bird behaviour and flight patterns and nesting locations. figs.
Full Text Available Abstract The present paper summarizes the results of 3 years of observation made at six month intervals for six months at a time (18 field surveys in a man-made cave in Northern Latium (Central Italy from April 1992 to April 1995. Its aim is to analyze the main structural and dynamic features of a bat community which hibernates at the shelter. Rhinolophus ferrumequinum and especially Rhinolophus euryale are the most abundant species. Population dynamics of both species as well as that of Rhinoluphus hipposideros show higher levels of abundance between December and February of each semester. In mid-winter, large and sometimes mixed aggregations of Rhinolophus ferrumequinum and Rhinolophus euryale in deep hypothermia occur. A small number of Rhinolophus hipposideros, mainly adult males, was observed. The paper compares the structure of this community to the structure of another community of the same district which has been previously analyzed, in which Vespertilionidae, especially Miniopterus schreibersi, are much more abundant. Despite the difference in species composition, body size was found to be a significant and common feature (as highlighted by forearm length, of the dominant species in both communities, Rhinolophus euryale and Miniopterus schreibersi respectively.

Bats represent a key component in the dynamics of many terrestrial ecosystems, and one of the groups of mammals with the highest levels of diversification in the Neotropics. Here we describe the results of a study of the bat fauna from Yurubí National Park (mountain area in Northern Venezuela), that includes a taxonomic list and the characterization of some community attributes in forested areas. Data was collected from zoological collections and diversified sampling methods from February to July of 2009 in an altitudinal gradient (100-1 500m), with three principal ecological units: semideciduous, evergreen and cloud forests. We recorded 64 species grouped in five families (63% of the bats known from La Cordillera de la Costa), of which Phyllostomidae was the dominant taxa (42 species; 66% of total), followed by Vespertilionidae, Molossidae, Emballonuridae and Mormoopidae. The community with the highest taxonomic diversification was found in the lowest elevation range, while the lowest number of species was found at the highest range. Eleven trophic guilds were identified; the insectivorous guild was the richest, whereas the frugivorous was the most abundant. Our results allow us to indicate these forest ecosystems have an appropriate conservation status, taking into account the presence of a relatively high proportion of species from the subfamily Phyllostominae, as well as the presence of other species with conservation priorities. All these aspects, and the fact that this represents a reservoir of the biological diversity of the forest ecosystems of La Cordillera de la Costa, make this protected area of an essential conservation value, in a highly endangered bioregion by neighboring socio-economic growth.

The mechanisms underlying the high extant biodiversity in the Neotropics have been controversial since the 19th century. Support for the influence of period-specific changes on diversification often rests on detecting more speciation events during a particular period. The timing of speciation events may reflect the influence of incomplete taxon sampling, protracted speciation, and null processes of lineage accumulation. Here we assess the influence of these factors on the timing of speciation with new multilocus data for New World noctilionoid bats (Chiroptera: Noctilionoidea). Biogeographic analyses revealed the importance of the Neotropics in noctilionoid diversification, and the critical role of dispersal. We detected no shift in speciation rate associated with the Quaternary or pre-Quaternary periods, and instead found an increase in speciation linked to the evolution of the subfamily Stenodermatinae (∼18 Ma). Simulations modeling constant speciation and extinction rates for the phylogeny systematically showed more speciation events in the Quaternary. Since recording more divergence events in the Quaternary can result from lineage accumulation, the age of extant sister species cannot be interpreted as supporting higher speciation rates during this period. Instead, analyzing the factors that influence speciation requires modeling lineage-specific traits and environmental, spatial, and ecological drivers of speciation. PMID:26865275

Twelve specimens of the bat Cormura brevirostris (Emballonuridae: Chiroptera) were collected from four localities in the Brazilian Amazon region and analyzed by classical and molecular cytogenetics. The diploid number and autosomal fundamental number were as previously reported (2n = 22 and FNa = 40, respectively). Fluorescence in situ hybridization using rDNA probes and silver nitrate technique demonstrated the presence of two NOR sites and the presence of internal telomeric sequences at pericentromeric regions of all chromosomes with exception of Y. Based on meiotic studies and chromosome banding we suggest that the sex chromosome pair of C. brevirostris was equivocally identified as it appears in the literature. Meiotic analysis demonstrated that at diplotene-diakinesis the cells had a ring conformation involving four chromosome pairs. This suggests the occurrence of multiple reciprocal translocations among these chromosomes, which is a very rare phenomenon in vertebrates, and has never been described in Eutheria. PMID:27300547

A new species of broad-nosed bat Platyrrhinus Saussure, 1860 (Chiroptera: Phyllostomidae: Stenodermatinae) from the Guianan Shield is described based on molecular and morphological data. Previously confused with P. helleri and P. recifinus, the new taxon is currently known from only Guyana and Suriname and is most closely related to P. recifinus from eastern Brazil and not to the two sympatric species (P. fusciventris and P. incarum) also recently recognized as distinct from P. helleri. Morphometrically the new taxon overlaps with the smaller species of the genus (P. angustirostris, P. brachycephalus, P. fusciventris, P. helleri, P. incarum, and P. matapalensis), but forms a different cluster from the larger P. recifinus. Morphologically the new taxon is distinguished from its congeners by a combination of external and craniodental characteristics. Platyrrhinus now includes 21 species making it the most speciose genus in the Neotropical family Phyllostomidae. PMID:24870671

The Neotropical bat genus Platyrrhinus (Chiroptera: Phyllostomidae: Stenodermatinae) currently comprises 15 species. Our morphological and morphometric analysis of large and medium-sized Platyrrhinus revealed a distinctive Undescribed species from western South America. We also recognize P. aquilus (Handley & Ferris 1972) and P. umbratus (Lyon 1902) as valid species. We describe P. nitelinea sp. nov. from western Colombia and Ecuador and provide emended diagnoses along with descriptions of P. aquilus, P.. dorsalis, and P. umbratus. Phylogenetic analysis of Platyrrhinus based on morphological characters indicates that P. aquilus is closely related to P. aurarius and P. nigellus, P. umbratus to P. chocoensis, and P. nitelinea to P. vittatus.

In October 2001 and September 2010, the chiropteni in Yunhua Karat Care of Henan Province was investigated. The results showed that chiroptera in this area belong to 4 families, 4 genera and 7 species. Among them, 4 species (57.1%) were Oriental realm spe cies, and 3 species (42.9% ) were cosmopolitan species. According to the present status of chiroptera resources in Yunhua Karat Cave, de tailed countermeasures for bat protection were put forward.%2001年10月和2010年9月,对河南省西峡县云华洞翼手目动物进行了调查.通过标本采集、鉴定分类,初步查明该溶洞分布翼手目动物共7种,隶属4科4属.其中,东洋界种4种,占总数的57.1％；广布种3种,占总数的42.9％.此外,根据蝙蝠资源的现状,提出了具体的保护建议.
Full Text Available Between 1989 and 1995, twenty caves in the Distrito Federal area in mid-western Brazil were assessed for bat species richness, frequency, spatial distribution, behavior, reproduction and inter-specific cohabitation. The general state of conservation of the caves was also assessed. Of the 20 caves studied, 12 were less than 100 m long, five between 100 m and 300 m, and three were longerthan 300 m. Twenty-two species of six different families were observed: 16 species belonged to Phyllostomidae, two to Vespertilionidae and Mormoopidae and one to Furipteridae and Emballonuridae. In this study, 17 species were characterized as Distrito Federal cave dwellers. The most prevalent were Desmodus rotundus, Glossophaga soricina and Carollia perspicillata. The least prevalent were Lonchorhina aurita, Pteronotus gymnonotus and Phylloderma stenops. Since some Anoura caudifer, Platyrrhinus lineatus, Myotis nigricans, Micronycteris minuta, and Eptesicus brasiliensis individuals were captured only while going into the caves early in the night, they were not considered cave dwellers. Even though, they probably use the caves as a daytime roosting place. Surprisingly, Lonchophylla dekeyseri, considered to be the only endemic bat species in the Cerrado ecosystem, was observed in three of the surveyed caves. Further biological studies are necessary to determine the biology of L. dekeyseri and the necessity of its conservation. The bat colonies observed were usually of a small size. Few colonies of D. rotundus and Anoura geoffroyi contained more than 300 individuals of both sexes. Only a inale group of L. aurita was observed in the Distrito Federal area. Twelve of the surveyed caves were hard to access and therefore well protected. Four of the caves received some public visitation, two were located near limestone mines, one was located near an urban area. and one had both public visitation and deforestation near its entrance. In this latter cave, no bats were observed

Most natural forests have been converted for human use, restricting biological life to small forest fragments. Many animals, including some species of bats are disappearing and the list of these species grows every day. It seems that the destruction of the habitat is one of its major causes. This study aimed to analyze how this community of bats was made up in environments with different sizes and quality of habitat. Data from studies conducted in the region of Londrina, Parana, Brazil, from 1982 to 2000 were used. Originally, this area was covered by a semi deciduous forest, especially Aspidosperma polyneuron (Apocynaceae), Ficus insipida (Moraceae), Euterpe edulis (Arecaceae), Croton floribundus (Euforbiaceae), and currently, only small remnants of the original vegetation still exist. The results showed a decline in the number of species caught in smaller areas compared to the largest remnant. In about 18 years of sampling, 42 species of bats were found in the region, representing 67% of the species that occur in Paraná and 24.4% in Brazil. There were two species of Noctilionidae; 21 of Phyllostoma; 11 Vespertilionidae and eight Molossidae. Eight of these were captured only in the largest fragment, Mata dos Godoy State Park (680 ha). Ten species had a low capture rate in the smaller areas with less than three individuals. Of the total sampled, 14 species were found in human buildings, and were able to tolerate modified environments, foraging and even using them as shelter. As the size of the forest area increases, there is a greater variety of ecological opportunities and their physical conditions become more stable, i.e., conditions favorable for growth and survival of a greater number of species. Forest fragmentation limits and creates subpopulations, preserving only long-lived K-strategist animals for some time, where the supporting capacity of the environment is a limiting factor.

Background New World leaf-nosed bats, Phyllostomidae, represent a lineage of Chiroptera marked by unprecedented morphological/ecological diversity and extensive intergeneric chromosomal reorganization. There are still disagreements regarding their systematic relationships due to morphological convergence among some groups. Their history of karyotypic evolution also remains to be documented. Results To better understand the evolutionary relationships within Phyllostomidae, we developed chromosome paints from the bat species Macrotus californicus. We tested the potential of these paints as phylogenetic tools by looking for chromosomal signatures in two lineages of nectarivorous phyllostomids whose independent origins have been statistically supported by molecular phylogenies. By examining the chromosomal homologies defined by chromosome painting among two representatives of the subfamily Glossophaginae (Glossophaga soricina and Anoura cultrata) and one species from the subfamily Lonchophyllinae (Lonchophylla concava), we found chromosomal correspondence in regions not previously detected by other comparative cytogenetic techniques. We proposed the corresponding human chromosomal segments for chromosomes of the investigated species and found two syntenic associations shared by G. soricina and A. cultrata. Conclusion Comparative painting with whole chromosome-specific paints of M. californicus demonstrates an extensive chromosomal reorganization within the two lineages of nectarivorous phyllostomids, with a large number of chromosomes shared between M. californicus and G. soricina. We show that the evolution of nectar-feeding bats occurs mainly by reshuffling of chiropteran Evolutionarily Conserved Units (ECUs). Robertsonian fusions/fissions and inversions seem to be important modifiers of phyllostomid karyotypes, and autapomorphic character states are common within species. Macrotus californicus chromosome paints will be a valuable tool for documenting the pattern of

Full Text Available A estrutura de comunidades de morcegos no Brasil ainda é pouco estudada e vêm sofrendo sérias modificações devido à perda de habitats. O principal objetivo do presente trabalho foi estudar a comunidade de morcegos da Estação Experimental de Itirapina, município de Itirapina, Estado de São Paulo. Nesta Estação, além das espécies cultivadas de Eucalyptus e Pinus, há diversas plantas que podem fornecer alimento aos morcegos. Entre julho de 2001 e julho de 2006, foram realizadas 58 sessões noturnas de captura de morcegos com 4 a 12 redes-de-neblina dispostas a cada sessão. Nesse período, foram capturados 720 indivíduos de 16 espécies de morcegos dos quais 13 pertencem à família Phyllostomidae, duas à Vespertilionidae e uma à Molossidae. A curva cumulativa de espécies atingiu o equilíbrio, no qual apenas espécies raras são acrescentadas. Cinco espécies (Artibeus lituratus, Platyrrhinus lineatus, Carollia perspicillata, Glossophaga soricina e Sturnira lilium representaram 80% dos morcegos capturados na Estação Experimental, onde se alimentavam de frutos de plantas pioneiras, tais como Cecropia pachystachya, Solanum spp. e Piper spp. A prevalência do vírus rábico foi zero na amostragem das 10 espécies analisadas. Apesar de estar muito modificada, a Estação Experimental de Itirapina pode ser uma importante área de abrigo e alimento para os morcegos e tem potencial de atuar como corredor entre áreas de Cerrado e Mata Atlântica.

Full Text Available To establish a technique which minimized the effects of fixation on the extraction of DNA from formalin-fixed tissues preserved in scientific collections we extracted DNA samples from fixed tissues using different methods and evaluated the effect of the different procedures on PCR and sequencing analysis. We investigated muscle and liver tissues from museum specimens of five species of fruit-eating (frugivorous bats of the Neotropical genus Artibeus (Chiroptera, Phyllostomidae: A. fimbriatus, A. lituratus, A. jamaicensis, A. obscurus, and A. planirostris. The results indicated that treatment of tissues in buffered solutions at neutral pH and about 37 °C for at least four days improves the quality and quantity of extracted DNA and the quality of the amplification and sequencing products. However, the comparison between the performance of DNA obtained from fixed and fresh tissues showed that, in spite of the fact that both types of tissue generate reliable sequences for use in phylogenetic analyses, DNA samples from fixed tissues presented a larger rate of errors in the different stages of the study. These results suggest that DNA extracted from formalin-fixed tissue can be used in molecular studies of Neotropical Artibeus bats and that our methodology may be applicable to other animal groups.

Full Text Available Bone tissue has different models of vascularization, cellular distribution, mineralization and remodeling among mammals species. A variety of dietary habits associated with the mode of locomotion and habitat required from bats the establishment of different flying styles and some skeletal adaptations. This study aimed at examining the microscopic characteristics of mature bone tissue of Glossophaga soricina (Phyllostomidae, Chiroptera. Twelve animals of both genders were used, in which the right humerus were dissected, weighed, decalcified and submitted to routine histological processing. Semi-serial cuts of 5 micrometers were stained with hematoxylin and eosin (H.E., picrosirius red and silver nitrate 50%. The histological preparations were subjected to histological and histomorphometric analysis. Lacunae density was significantly higher in humerus of females when compared to males (33.96 x 27.80, p = 0.02. Microscopic analysis indicated the presence of parallel collagen fibers distributed in the bone matrix. Lacunes presented various shapes and canaliculi are well distributed and individualized. Few Havers systems and canals were observed. The mature bone tissue of the humerus Glossophaga soricina share microscopic features with other mammals, however, differences in the structural organization are peculiar to this species.

Aerodynamic theory predicts that flight for fixed-wing aircraft requires more energy at low and high speeds compared with intermediate speeds, and this theory has often been extended to predict speed-dependent metabolic rates and optimal flight speeds for flying animals. However, the theoretical U-shaped flight power curve has not been robustly tested for Chiroptera, the only mammals capable of flapping flight. We examined the metabolic rate of seven Seba's short-tailed fruit bats (Carollia perspicillata) during unrestrained flight in a wind tunnel at air speeds from 1 to 7 m s(-1). Following intra-peritoneal administration of (13)C-labeled Na-bicarbonate, we measured the enrichment in (13)C of exhaled breath before and after flight. We converted fractional turnover of (13)C into metabolic rate and power, based on the assumption that bats oxidized glycogen during short flights. Power requirements of flight varied with air speed in a U-shaped manner in five out of seven individuals, whereas energy turnover was not related to air speed in two individuals. Power requirements of flight were close to values predicted by Pennycuick's aerodynamic model for minimum power speed, but differed for maximum range speed. The results of our experiment support the theoretical expectation of a U-shaped power curve for flight metabolism in a bat. PMID:23430989

Full Text Available With over 130 species, bats are the most diverse group of mammals almost everywhere in sub-Saharan Africa. Since 2000, two books (Monadjem et al. 2010; Taylor 2000 have made it much easier to appreciate this reality. Species previously unrecognised are frequent discoveries (e.g. Taylor et al. 2012. Whilst most species are mainly insectivorous, some rely more directly on plants, taking fruit and visiting flowers to obtain nectar and pollen. The combination of mobility, long lifespan and diversity of trophic roles makes bats potentially valuable as indicators of ecosystem health (Cumming & Spiesman 2006. Lack of detailed information, however, makes it easy to overlook bats when focusing on issues of conservation.

As ocorrências do terceiro molar superior em A. lituratus e do segundo pré-molar superior em A. fimbriatus são casos de atavismos. Em Artibeus (Artibeus ocorrem variações quanto à presença do terceiro molar superior, de maior ou menor intensidade, em praticamente todas as espécies. Estas variações ocorrem tanto a nível intrapopulacional quanto geográfico. Já o terceiro molar inferior está ausente em baixa freqüência em várias populações de diferentes espécies. Os terceiros molares superiores e inferiores estão em processo de desaparecimento na linhagem dos Artibeus (Artibeus. O fato destes dentes já não ocorrerem em algumas espécies, terem ocorrência variável em outras e serem sempre estruturas reduzidas e simplificadas, sem função na mastigação, são indicativos deste processo evolutivo. A variação intensa observada quanto à ocorrência do terceiro molar superior inviabiliza o seu uso como caráter útil na identificação de espécies.This paper describes and analyzes the causes of dental formula anomalies in the bats Artibeus lituratus (Olfers, 1818 and Artibeus fimbriatus Gray, 1838

Full Text Available External morphological characters of 141 young specimens (69 males and 72 femalesof the Bothrops newied complex were analyzed. Regression analysis was used in the study of morphometric characters and principal components analysis was used in the study of meristic and qualitative characters. Sexual dimorphism was confirmed in the meristic and morphometric characters. Males showed higher counts of subcaudals and longer tails. Females showed eventually higher number of ventrals and dorsal rows, and larger heads. Six different drawing patterns were diagnosed and can indicate the existence of different species. Ontogenetic variation was described.
There have been different ideas over whether or not the Qinling and Daba mountain ranges are part of the dividing line in Central China between the Palaearctic realm and the Oriental realm in the zoogeographical distribution of animals. Our predecessors have tried to prove this hypothesis from the perspectives of different disciplines by conducting surveys of birds, fishes, amphibians, reptiles and some mammals. The authors have carried out 3 major collections of bat ( CHIROPTERA) specimens in the Qinling and Daba mountain ranges since 1964. Over 2 000 obtained specimens were I-dentified and classified as 32 species belonging to 4 families and 4 subfamilies. The analytical results indicate that 23 species belong to the Oriental realm, accounting for 71. 8% of the total, and 9 belong to the Palaearctic realm, accounting for 28. 2%. These species are all seen in every Chinese zoogeographic region and their frequencies range as follows: Central China region, Southwest China region, South China region, North China region, Inner Mongolia-Xinjiang region, and Qinghai-Xizang region. Some of China' s endemic genera and species, including monotypic ones, also are distributed in the Qinling and Daba mountain ranges. The authors believe that bats are a class affected by climate, topography, and vegetation , and their geographic distribution is relatively sensitive and therefore restricted. According to the regional composition and distribution characteristics of bats in the Qinling and Daba ranges, the Oriental realm is limited to the northern slopes of Qinling range while the Palaearctic realm gradually declines in number from the southern slopes of Qinling range to the northern slopes of Daba range. There is a gradual transition for bats between the two realms in the southern slopes of the Qinling range and the northern slopes of Daba range, demonstrating that this is a transitional region for bats. All this further proves that the view is correct to consider the Qinling

The global effort to digitize biodiversity occurrence data from collections, museums and other institutions has stimulated the development of important tools to improve the knowledge and conservation of biodiversity. The Global Biodiversity Information Facility (GBIF) enables and opens access to biodiversity data of 321 million of records, from 379 host institutions. Neotropical bats are a highly diverse and specialized group, and the geographic information about them is increasing since few years ago, but there are a few reports about this topic. The aim of this study was to analyze the number of digital records in GBIF of Neotropical bats with distribution in 21 American countries, evaluating their nomenclatural and geographical consistence at scale of country. Moreover, we evaluated the gaps of information on 1 degrees latitude x 1 degrees longitude grids cells. There were over 1/2 million records, but 58% of them have no latitude and longitude data; and 52% full fit nomenclatural and geographic evaluation. We estimated that there are no records in 54% of the analyzed area; the principal gaps are in biodiversity hotspots like the Colombian and Brazilian Amazonia and Southern Venezuela. In conclusion, our study suggests that available data on GBIF have nomenclatural and geographic biases. GBIF data represent partially the bat species richness and the main gaps in information are in South America. PMID:24912354

Full Text Available Nowadays there are several renewable energy technologies that transform natural energy from energy available to humans. In this article, we review the barriers that do not facilitate the implementation of renewable energy technologies in the system for interconnection of two representatives of developed countries (Denmark and Spain as well as a representative of developing countries(Chile. From the above, is that representatives of developed countries have led to a signiÞ cant penetration of renewable energy sources within their territories, in contrast to the representative of the underdeveloped countries, where those are in a transition phase. Hence, probably the strategies implemented by developed countries are a model for developing countries. Finally, we conclude that all causes problems contribute to increasing investment costs of renewable energy sources, in effect, given that these costs should be less thanthe beneÞ ts generated by those on promoting their real penetration in the developing countries.

In this study, we report the complete mitochondrial genome sequence of brandt's bat, Myotis brandtii. The genome is found to be 17,470 bp in length and has a base composition of A (33.1%), G (13.6%), C (24.6%), and T (28.6%). Similar to other bats, it contains a typically conserved structure including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region (D-loop). Most of the genes are encoded on H-strand, except for the eight tRNA and ND6 genes. All protein-coding genes start with an ATG codon except for ND2, ND3 and ND5, which initiate with ATC or ATA instead, and terminate with the typical stop codon (TAA/TAG) or a single T (T- -) or an unexpected codon of AGA. The complete mitochondrial genome sequence provided here would be useful for further phylogenetic analysis and population genetic studies in M. brandtii. PMID:25103443

We describe Lonchophylla orcesi, sp. nov., from the Choco, a region of high biotic diversity, endemism, and rainfall along the western Andean slopes and Pacific lowlands of Colombia and Ecuador. One of the largest known Lonchophylla, it occurs sympatrically with at least two other species of Lonchophylla including the similar, but somewhat smaller L. robusta. We also recognize L. concava as a Middle American Province species distinct from L. mordax of Brazil and Bolivia on the basis of cranial and dental features.

We observed that the karyotypes were also cytogenetically similar when we compared the studied species with other species within the same genus. It is therefore not possible to differentiate the species using only karyotypes with conventional staining. However, this information increases the knowledge of the genus and can be one more important character for a better phylogenetic comprehension of this taxon. PMID:27186341

In 1868, Wilhelm Peters described Glossonycteris lasiopyga, based on a specimen provided by Henri de Saussure and collected in Mexico. The type specimen was presumed to be among those housed in the collections of the Zoologisches Museum of the Humboldt Universitat in Berlin, Germany. Our study of one of Saussure?s specimens from Mexico, discovered in the collections of the Museum d?Histoire Naturelle, Geneva, Switzerland, demonstrates that it and not one of the Berlin specimens is the holotype.

The geographic origin of bats is still unknown, and fossils of earliest bats are rare and poorly diversified, with, maybe, the exception of Europe. The earliest bats are recorded from the Early Eocene of North America, Europe, North Africa and Australia where they seem to appear suddenly and simultaneously. Until now, the oldest record in Asia was from the Middle Eocene. In this paper, we report the discovery of the oldest bat fauna of Asia dating from the Early Eocene of the Cambay Formation at Vastan Lignite Mine in Western India. The fossil taxa are described on the basis of well-preserved fragments of dentaries and lower teeth. The fauna is highly diversified and is represented by seven species belonging to seven genera and at least four families. Two genera and five species are new. Three species exhibit very primitive dental characters, whereas four others indicate more advanced states. Unexpectedly, this fauna presents strong affinities with the European faunas from the French Paris Basin and the German Messel locality. This could result from the limited fossil record of bats in Asia, but could also suggest new palaeobiogeographic scenarios involving the relative position of India during the Early Eocene.

Ticks associated with bats have been poorly documented in the Neotropical Zoogeographical Region. In this study, a total of 1028 bats were sampled for tick infestations in the southern portion of the Brazilian Pantanal. A total of 368 ticks, morphologically identified as Ornithodoros hasei (n = 364) and O. mimon (n = 4), were collected from the following bat species: Artibeus planirostris, Platyrrhinus lineatus, Phyllostomus hastatus, Mimon crenulatum and Noctilio albiventris. Morphological identification of O. hasei was confirmed by molecular analysis. Regarding the most abundant bat species, only 40 (6.2 %) out of 650 A. planirostris were infested by O. hasei, with a mean intensity of 7.2 ticks per infested bat, or a mean abundance of 0.44 ticks per sampled bat. Noteworthy, one single P. hastatus was infested by 55 O. hasei larvae, in contrast to the 2.5-7.2 range of mean intensity values for the whole study. As a complement to the present study, a total of 8 museum bat specimens (6 Noctilio albiventris and 2 N. leporinus), collected in the northern region of Pantanal, were examined for tick infestations. These bats contained 176 ticks, which were all morphologically identified as O. hasei larvae. Mean intensity of infestation was 22, with a range of 1-46 ticks per infested bat. Our results suggest that A. planirostris might play an important role in the natural life cycle of O. hasei in the Pantanal. PMID:26912332

Full Text Available In Brazil, there are two published references on the diet of American kestrel falcons, Falco sparverius Linnaeus, 1758, and one is for the Cerrado biome. The only mammal prey so far found in the diet of F. sparverius was the rodent Calomys tener (Winge, 1887. Herein we report on daily hunting activities by American kestrel falcons at a factory in the city of Uberlândia, state of Minas Gerais, southeastern Brazil, during an attempt to remove a bat colony. Two American kestrel falcons were observed on 14 occasions during two consecutive days: in two of these occasions, they were hunting in pairs, from 12:00 p.m. to 3:00 p.m. on 06/X/2003, and from 07:00 a.m. to 11:00 a.m. on 07/X/2003. During this period, American kestrel falcons made 27 hunting attempts and captured four bats of the same species, Nyctinomops laticaudatus (E. Geoffroy St.-Hilaire, 1805 (14.81% success. This report corroborates observations made in the Northern hemisphere, where bats are a dietary item of this falcon. Our findings are noteworthy because they reveal that the known natural predators of bats are few not only in Brazil but also worldwide.

Results of the use of the fingerprinting method related to short interspersed elements (SINEs), inter-SINE-PCR, in the study of phylogenetic and taxonomic relationship in mammals from orders Chiroptera (family Vespertilionidae) and Lipotyphla (family Erinaceidae) are reported. The inter-SINE-PCR method is based on the amplification of fragments situated between copies of SINEs, which are short retroposons spaced 100 to 1000 bp apart. Specifically selected primers were used, which are complementary to consensus sequences of two short retroposons: the mammalian interspersed repeat (MIR), which is typical of all mammals and some other vertebrates, was used in the cases of bats and Erinaceidae, and the ERI-1 element recently isolated from the genome of the Daurian hedgehog was used in the case of Erinaceidae. The results support the current view on phylogenetic relationship between hedgehogs belonging to genera Erinaceus, Hemiechinus, and Paraechinus (but not the genus Atelerix). In bats, the phylogenetic reconstruction revealed a statistically valid topology only at lower taxonomic levels, whereas the topology for the genus and supragenus ranks was unresolved and fan-shaped. The benefits and limitations of the inter-SINE-PCR method are discussed. PMID:12138785

Full Text Available The recent discovery of genetically distinct hantaviruses in multiple species of shrews and moles prompted a further exploration of their host diversification by analyzing frozen, ethanol-fixed and RNAlater®-preserved archival tissues and fecal samples from 533 bats (representing seven families, 28 genera and 53 species in the order Chiroptera, captured in Asia, Africa and the Americas in 1981–2012, using RT-PCR. Hantavirus RNA was detected in Pomona roundleaf bats (Hipposideros pomona (family Hipposideridae, captured in Vietnam in 1997 and 1999, and in banana pipistrelles (Neoromicia nanus (family Vespertilionidae, captured in Côte d’Ivoire in 2011. Phylogenetic analysis, based on the full-length S- and partial M- and L-segment sequences using maximum likelihood and Bayesian methods, demonstrated that the newfound hantaviruses formed highly divergent lineages, comprising other recently recognized bat-borne hantaviruses in Sierra Leone and China. The detection of bat-associated hantaviruses opens a new era in hantavirology and provides insights into their evolutionary origins.

Full Text Available In order to clarify the distribution of bats of the genus Lasiurus in Colombia, we performed a morphological study of 49 specimens from four Colombian collections. Our review confirms the presence of three species in Colombia (L. blossevillii, L. cinereus, and L. ega with distribution in all natural regions that include six of the nine biogeographic provinces. These species can be easily differentiated based on external and cranial characters. Lasiurus cinereus is the largest species (forearm length > 52 mm and L. blossevillii is the smallest (forearm < 42 mm; L. ega has a distinctive skull shape with a developed sagittal crest. While previous literature make claims that L. egregius and L. castaneus occur in Colombia, our analysis found no support for this and even contradicts the evidence cited for their presence in the country. We demonstrate that one specimen attributed to L. egregius in literature corresponds to a misidentified L. blossevillii. Furthermore, we found that there are not any specimens of L. castaneus from the Department of Cundinamarca despite several reports in the literature. The status of subspecies in Colombia remains controversial and more specimens are needed to determine whether there are clear distinctions between forms in any geographical region. Most of the specimens examined were males and in some cases, were collected opportunistically from dead individuals found in cities in the Andean region.

Full Text Available The bay of the Tibagi river, a place which goes through quick environmental alterations, has three forest fragments: the "Floresta Nacional do Irati" (3.572 ha, the "Reserva Biológica da Klabin" (11.116 ha and the "Parque Estadual Mata dos Godoy" (680 ha. Here, Myotis ruber (E. Geoffroy, 1806 and Chiroderma doriae Thomas, 1891 can be found, these are threatened bats, and three species, Pygoderma bilabiatum (Wagner, 1843, Myotis levis (I. Geoffroy, 1824 and Rogheessa tumida H. Allen, 1866, which are presumably threatened. Using the same effort of capture in the three places, it was stated that the "Floresta Nacional do Irati" with low vegetation diversity, showed nine species of bats. The "Parque Estadual Mata dos Godoy", although it's five times smaller, fifteen species. We came to the conclusion that a big reserve, without good conditions would house a lower number of species. A small reserve with adequate resources and great vegetation diversity presents a higher number of niches, housing a higher number of species.

Full Text Available Study carried out within the urban perimeter of Londrina, which is located in the North of the state of Paraná. The objectives were the identification of urban species of bats and diurnal roosts used by them and the verification of the problems they can cause to the population. The fire brigade, the Autarquia Municipal do Ambiente de Londrina (Municipal Environment Autarchy of Londrina, the Biology Department of the Universidade Estadual de Londrina (State University of Londrina and local residents helped spot the roosts. The collections were carried out in regular intervals between April 1998 and March 1999. By the end of them, 815 bats of 23 different species had been captured. Among these, 12 were found near or inside human constructions: Noctilio albiventris Desmarest, 1818; Artibeits lituratus (Olfers, 1818; Platyrrhinus lineatus (E. Geoffroy, 1810; Eptesicus brasiliensis Desmarest 1819; Lasiurus bore-alls (Muller 1776; Lasiurus ega (Gervais, 1856; Eumops glaucinus (Wagner, 1843; Molossus rufus (E.

Roost sites comprised expansion joints, roofs, attics and parks, among others. It can be concluded that bats are treated as undesirable animals by the population due to the lack of knowledge about the subject.

From September to November 2007, we recorded and analyzed the echolocation calls of Ricketti' s big-footed bat (Myotis ricketti) , in call-recording cages using BatSound software. We also calculated measurements of wing shape for these bats. We compared the parameters of echolocation calls and wing shape between males and females. The results showed that only the interpulse interval was significantly different between males (68.49 ± 10. 99 ms) and females (83. 61±13. 77 ms) (t-test: t=-2.72, P <0. 01), while the pulse duration (male: 4. 28 ±0. 34 ms, female: 4. 64 ± 0. 97 ms) , the dominant frequency (40. 31±1. 36 kHz, 40. 20±1. 32 kHz ), the max frequency (72. 40 ±2. 37 kHz, 72. 20 ±2. 66 kHz), the min frequency (29. 00 ±1. 16 kHz, 28. 60 ± 1. 58 kHz) ,and the measurements of wing shape were not significantly different between males and females.

From over 1250 extant species of the order Chiroptera, 25 and 28 are known to occur in Germany and Hungary, respectively. Close to 350 samples originating from 28 bat species (17 from Germany, 27 from Hungary) were screened for the presence of adenoviruses (AdVs) using a nested PCR that targets the DNA polymerase gene of AdVs. An additional PCR was designed and applied to amplify a fragment from the gene encoding the IVa2 protein of mastadenoviruses. All German samples originated from organs of bats found moribund or dead. The Hungarian samples were excrements collected from colonies of known bat species, throat or rectal swab samples, taken from live individuals that had been captured for faunistic surveys and migration studies, as well as internal organs of dead specimens. Overall, 51 samples (14.73%) were found positive. We detected 28 seemingly novel and six previously described bat AdVs by sequencing the PCR products. The positivity rate was the highest among the guano samples of bat colonies. In phylogeny reconstructions, the AdVs detected in bats clustered roughly, but not perfectly, according to the hosts' families (Vespertilionidae, Rhinolophidae, Hipposideridae, Phyllostomidae and Pteropodidae). In a few cases, identical sequences were derived from animals of closely related species. On the other hand, some bat species proved to harbour more than one type of AdV. The high prevalence of infection and the large number of chiropteran species worldwide make us hypothesise that hundreds of different yet unknown AdV types might circulate in bats. PMID:26599097

The reproductive tract was examined in four non-pregnant and two gravid specimens of Myzopoda. The ovaries had little interstitial tissue. The uterus was bicornuate and the lenticular placental disk was situated mesometrially in one horn. The interhaemal barrier of the placental labyrinth was of the endotheliomonochorial type. There was a single layer of trophoblast cells. The cells of the maternal endothelium were large and basophilic, contained abundant rough endoplasmic reticulum, and rested on an irregular basement membrane. Blunt projections of endometrium extended into the placental disk and clusters of large cells occurred between the endometrial stroma and labyrinth. At the margins of the disk folds of trophoblast occurred and at the cranial end they formed an haemophagous region. The folds lateral to the disk included some peculiar tubular-appearing structures. There was a persistent yolk sac containing large endodermal cells around a largely collapsed lumen. Several features of placentation, such as the interhaemal barrier and the haemophagous region, are consistent with an association of Myzopodidae with Emballonuridae. No support was found for alternative hypotheses that include Myzopodidae in the noctilionoid or vespertilionoid lineages. PMID:18374977

Además, algunas poblaciones colombianas de Phyllostomus hastatus fueron nombradas subespecies y sinonimizadas hace más de 60 años, y existe confusión en la separación y distribución de P. elongatus y P. latifolius. En este trabajo se analizó la variación morfométrica y morfológica entre y dentro de las especies de Phyllostomus en Colombia. Los resultados muestran que P. discolor presenta dimorfismo sexual secundario, pero no variación geográfica entre las poblaciones de cada lado de la vertiente oriental de los Andes; P. discolor puede ser monotípica o la zona de contacto entre las dos subespecies reconocidas no se halla en Colombia. Existen dos grupos morfométricos de P. hastatus, uno corresponde a las poblaciones distribuidas al occidente de la vertiente oriental de los Andes y corresponde a P. hastatus panamensis y otro a las poblaciones distribuidas al oriente de los Andes que corresponden a la forma nominal.

Full Text Available The Caatinga-endemic nectar-feeding bat, Xeronycteris vieirai Gregorin & Ditchfield, 2005 was described based on four specimens. Since then, only two additional specimens have been reported in the literature. Examination of a new specimen that closely agrees with the original description but presents two additional upper premolars, led us to review the type series of this taxon. Our analysis provided support to the recognition of the new specimen as a X. vieirai with supernumerary teeth and revealed new diagnostic characters that can help in the field identification of this species. Xeronycteris vieirai presents tricolored dorsal fur, entirely naked forearm, connection of the base of the spear of the noseleaf with the upper limit of the horseshoe with a marked ridge, and chin with simple dermal pads and a relatively slight cleft. Additional new characters described here include anterior zygomatic arches reduced and not extending laterally and upward with respect to upper toothrow, basioccipital pits deep and separated by a high and thin bone septum, and mandible with a pronounced ridge at anterior symphysis. We propose an emended diagnosis based on morphological characters and provide a rectification on the original notation related to the holotype.

Full Text Available Abstract Background Bats of the family Phyllostomidae show a unique diversity in feeding specializations. This taxon includes species that are highly specialized on insects, blood, small vertebrates, fruits or nectar, and pollen. Feeding specialization is accompanied by morphological, physiological and behavioural adaptations. Several attempts were made to resolve the phylogenetic relationships within this family in order to reconstruct the evolutionary transitions accompanied by nutritional specialization. Nevertheless, the evolution of nectarivory remained equivocal. Results Phylogenetic reconstructions, based on a concatenated nuclear-and mitochondrial data set, revealed a paraphyletic relationship of nectarivorous phyllostomid bats. Our phylogenetic reconstructions indicate that the nectarivorous genera Lonchophylla and Lionycteris are closer related to mainly frugivorous phyllostomids of the subfamilies Rhinophyllinae, Stenodermatinae, Carolliinae, and the insectivorous Glyphonycterinae rather than to nectarivorous bats of the Glossophaginae. This suggests an independent origin of morphological adaptations to a nectarivorous lifestyle within Lonchophyllinae and Glossophaginae. Molecular clock analysis revealed a relatively short time frame of about ten million years for the divergence of subfamilies. Conclusions Our study provides strong support for diphyly of nectarivorous phyllostomids. This is remarkable, since their morphological adaptations to nutrition, like elongated rostrums and tongues, reduced teeth and the ability to use hovering flight while ingestion, closely resemble each other. However, more precise examinations of their tongues (e.g. type and structure of papillae and muscular innervation revealed levels of difference in line with an independent evolution of nectarivory in these bats.

The greatest current threat to terrestrial fauna is continuous and severe landscape modification that destroys and degrades animal habitats. This rapid and severe modification has threatened species, local biological communities, and the ecological services that they provide, such as seed dispersal, insect predation, and pollination. Bats are important pollinators of the Cerrado (woodland savanna) because of their role in the life cycles of many plant species. However, there is little informa...

A limited number of studies have focused on the population genetic structure of vampire bats (Desmous rotundus) in America. This medium-sized bat is distributed in tropical areas of the continent with high prevalence in forested livestock areas. The aim of this work was to characterize the vampire population structure and their genetic differentiation. For this, we followed standard methods by which live vampires (caught by mist-netting) and preserved material from scientific collections, were obtained for a total of 15 different locations, ranging from Chihuahua (North) to Quintana Roo (Southeast). Tissue samples were obtained from both live and collected animals, and the genetic differentiation, within and among localities, was assessed by the use of seven microsatellite loci. Our results showed that all loci were polymorphic and no private alleles were detected. High levels of heterozygosis were detected when the proportion of alleles in each locus were compared. Pairwise (ST) and R(ST) detected significant genetic differentiation among individuals from different localities. Our population structure results indicate the presence of eleven clusters, with a high percentage of assigned individuals to some specific collecting site. PMID:25102648

A new genus and associated species of false vampire, family Megadermatidae, are described based on three specimens from Bala Forest, Narathiwat Province, peninsular Thailand. The new taxon is characterised by a unique combination of distinctive dental, cranial, and external characters, some of which are shared with exclusively African genera and some with Asian genera. These characters are comparable to, or exceed in number, those differentiating currently recognised genera in the family Megadermatidae. They include the absence of a first upper premolar; greatly enlarged upper canine without an anterolingual cingular cusp but with a robust posterolingual cusp; unmodified upper first molar with the preparacrista subequal in length to the postmetacrista, the metastyle not reduced and situated labially; robust lower canine without an anterolingual cusp; the first lower premolar enlarged, equal to or larger than the second lower premolar. In the skull, there is a pronounced rostral depression but no well developed frontal shield with preorbital and/or postorbital processes; the coronoid process is greatly enlarged in each half mandible. Externally, the body size is relatively large and the posterior noseleaf is rounded. The baculum has a robust shaft and two short prongs-the bacula of all five other species of megadermatid are illustrated for the first time; extraordinarily, those of Macroderma gigas and Megaderma lyra comprise two separate bones. DNA barcoding indicate a genetic divergence of about 20 percent (sequence divergence in the mitochondrial gene CO1) between the new genus and species of Megaderma and Cardioderma. Currently, despite numerous bat surveys in peninsular Thailand, the new genus is only known from Bala Forest. The small area of this forest and the very low capture rate suggest that the new species may be extremely rare. Its natural history is little known, although its robust dental and cranial features when coupled with chance observations of its feeding behaviour, suggest it may specialise in eating large beetles. Its conservation status is considered to be at risk owing to the rapid loss of forest habitat in much of the Thai-Malay peninsula. PMID:25781844

Frugivorous and nectarivorous bats fuel their metabolism mostly by using carbohydrates and allocate the restricted amounts of ingested proteins mainly for anabolic protein syntheses rather than for catabolic energy production. Thus, it is possible that genes involved in protein (amino acid) catabolism may have undergone relaxed evolution in these fruit- and nectar-eating bats. The tyrosine aminotransferase (TAT, encoded by the Tat gene) is the rate-limiting enzyme in the tyrosine catabolic pathway. To test whether the Tat gene has undergone relaxed evolution in the fruit- and nectar-eating bats, we obtained the Tat coding region from 20 bat species including four Old World fruit bats (Pteropodidae) and two New World fruit bats (Phyllostomidae). Phylogenetic reconstructions revealed a gene tree in which all echolocating bats (including the New World fruit bats) formed a monophyletic group. The phylogenetic conflict appears to stem from accelerated TAT protein sequence evolution in the Old World fruit bats. Our molecular evolutionary analyses confirmed a change in the selection pressure acting on Tat, which was likely caused by a relaxation of the evolutionary constraints on the Tat gene in the Old World fruit bats. Hepatic TAT activity assays showed that TAT activities in species of the Old World fruit bats are significantly lower than those of insectivorous bats and omnivorous mice, which was not caused by a change in TAT protein levels in the liver. Our study provides unambiguous evidence that the Tat gene has undergone relaxed evolution in the Old World fruit bats in response to changes in their metabolism due to the evolution of their special diet.

The New Zealand endemic bat family Mystacinidae comprises just two Recent species referred to a single genus, Mystacina. The family was once more diverse and widespread, with an additional six extinct taxa recorded from Australia and New Zealand. Here, a new mystacinid is described from the early Miocene (19-16 Ma) St Bathans Fauna of Central Otago, South Island, New Zealand. It is the first pre-Pleistocene record of the modern genus and it extends the evolutionary history of Mystacina back at least 16 million years. Extant Mystacina species occupy old-growth rainforest and are semi-terrestrial with an exceptionally broad omnivorous diet. The majority of the plants inhabited, pollinated, dispersed or eaten by modern Mystacina were well-established in southern New Zealand in the early Miocene, based on the fossil record from sites at or near where the bat fossils are found. Similarly, many of the arthropod prey of living Mystacina are recorded as fossils in the same area. Although none of the Miocene plant and arthropod species is extant, most are closely related to modern taxa, demonstrating potentially long-standing ecological associations with Mystacina.

Full Text Available The stable microclimate in caves provides a relatively constant habitat for many bat species in the Philippines, but human encroachment continues to disrupt this habitat and imperil many of the species roosting in the caves. In South central Mindanao, the diversity and conservation status of cave bats remain undocumented and unexplored. We employed mist-netting to capture bats from five different caves within the town of Kabacan, northern Cotabato, Philippines. A total of 14 bat species were identified including the Philippine endemics Hipposideros pygmaeus and Ptenochirus jagori and the threatened Megaerops wetmorei. However, despite the declining conservation status of the bats, local disturbance such as bat hunting for bush meat and unregulated tourism are currently taking place in the caves. Large species such as Eonycteris spelaea and Rousettus amplexicaudatus are killed almost every day for food and trade. Therefore, the high species richness, and the presence of endemic and threatened species coupled with the occurrence of anthropogenic disturbances in caves suggests the need for an urgent and effective conservation intervention involving the local government and public community.

Full Text Available Saccopteryx leptura (Schreber, 1774 is reported from two new localities in southeastern Brazil, both in Atlantic forest remains in the state of Rio de Janeiro. Analysisof food material showed that individuals from both localities had preyedon insects in the order Hymenoptera. Cheek contents were available from one specimen, and in this case identification of the food item (flying ants achieved generic level (Pheidole Westwood, 1841. Aspects in the social behavior observed in a colony suggest that the same traits documented in Central American populations (small colonies, monogamic mating system, and retention of young for up to a year in the parental unit may also characterize this species in the southern most part of its range.

Based on count results, we estimated the population of Mariana fruit bats (Pteropus mariannus Desmarest) on Sarigan, Mariana Islands, to number 150-200 bats in 1999, 185-235 bats in 2000, and about 300-400 bats in 2001. Our results, plus those of two previous surveys, indicate that bat abundance on the island probably remained relatively stable at about 125-235 animals during much of the period from 1983 to 2000, then increased suddenly in 2001, most likely due to immigration from a neighboring island. Sarigan's population differs from those of larger islands in the archipelago by usually having smaller roost sizes, typically 3-75 bats, and large numbers of solitary bats that at times comprise up to half of the population. Colonies and smaller aggregations were composed primarily of harems with multiple females, whereas a nearly equal sex ratio occurred among solitary animals. Colonies roosted in isolated coconut trees in open grasslands and in native forest stands of various sizes, but avoided dense coconut forest. An estimated 30-50% of harem and solitary females possessed young in July 1999. Bats were recorded feeding on just six species of plants, which partly reflects the island's impoverished flora. We speculate that fruit bat abundance on Sarigan is limited primarily by food availability rather than hunting losses, in contrast to some other islands in the Marianas. Our study supports the contention that populations of P. mariannus in the northern Marianas are usually sedentary, but that interisland movements of larger numbers of bats may occur rarely. ?? 2004 by University of Hawai'i Press All rights reserved.

Platyrrhinus is a diverse genus of small to large phyllostomid bats characterized by a comparatively narrow uropatagium thickly fringed with hair, a white dorsal stripe, comparatively large inner upper incisors that are convergent at the tips, and three upper and three lower molars. Eighteen species are currently recognized, the majority occurring in the Andes. Molecular, morphological, and morphometric analyses of specimens formerly identified as Platyrrhinus helleri support recognition of Platyrrhinus incarum as a separate species and reveal the presence of two species from western and northern South America that we describe herein as new (Platyrrhinus angustirostris sp. nov. from eastern Colombia and Ecuador, north-eastern Peru, and Venezuela and Platyrrhinus fusciventris sp. nov. from Guyana, Suriname, French Guiana, Trinidad and Tobago, northern Brazil, eastern Ecuador, and southern Venezuela). These two new species are sister taxa and, in turn, sister to Platyrrhinus incarum.

The Yasuni Round-eared bat, Lophostoma yasuni, was described in 2004 by morphological analysis of the holotype, the only specimen attributed to this taxon to date. A molecular analysis using cytochrome-b sequences and a new morpholo-gical analysis that includes the holotype of L. yasuni and two specimens of L. carrikeri from near the type locality of L. yasuni were carried out. The new molecular and morphological evidence places L. yasuni within the clade of L. carrikeri. We propose that L. yasuni should therefore be considered as a synonym of L. carrikeri. An emended diagnosis for L. carrikeri extending ranges of craniodental measurements for this species is presented. PMID:27395128
Full Text Available Nudacotyle carollia sp. nov. (Trematoda, Nudacotylidae is described on the basis of specimens from the intestinal tracts of three Colombian bats of the species Carollia perspicillata L. The new species resembles both of the genera of the family, Nudacotyle and Neocotyle, in the general position of the organs and in having a vertical cleft. It differs from Nudacotyle in the position of the ovary and cirrus sac and in the lenth of the ceca. The new species differs from Neocotyle in the shape of the body and the vitelline lobes and in the length of the ceca. The ventral cleft is considered to be an important generic character which can be used to unit all the species of both genera in the single genus, Nudacotyle.

The prostatic complex (ventral and dorsal regions) of Artibeus planirostris exhibits seasonal variations throughout the year. Circulating testosterone was correlated with prostate weight, showing an increase from autumn to summer, with the highest peak in summer corresponding to the largest breeding season. This indicates that the level of serum testosterone influences variations in both testicular and prostatic weights. Serum testosterone levels seem to be closely related to the different responses of these glands throughout the year. The castration (consequent suppression of testosterone) and subsequent hormone supplementation may elucidate the relationship of these two glandular types with testosterone. Thus, the aim of this study was to evaluate the effect of castration and the testosterone supplementation in the male prostatic complex of A. planirostris. The results indicated that both prostatic regions were affected by the ablation of testosterone, presenting a decrease in cell proliferation and an increase in apoptosis. Similarly, the prostate was responsive to hormonal supplementation, having a recovery of the active morphophysiological pattern with testosterone supplementation. However, data have shown that the ventral region was more sensitive to changes in testosterone than the dorsal, presenting greater cell renewal. PMID:27032910

We studied the potential contribution of frugivorous bats to the reestablishment of vegetational diversity in a restored area. We analysed the diets of the bat species and the differences between them in the consumption of fruits of autochtonous and allochthonous species. Planted (autochtonous) species were the basis of diets, especially Solanum mauritianum and Cecropia pachystachya, whereas for allochthonous species we found that Piperaceae to be of particular importance. Carollia perspicillata was the main seed disperser for allochthonous species, and potentially the most important bat in the promotion of vegetation diversity in the study area. Our results suggest that frugivorous bats are especially important in the reestablishment of vegetation in disturbed areas, and that restorarion efforts should focus on the planting of different zoochorous species that would guarantee a high year-round fruit production, thereby facilitating natural plant reestablishment by frugivorous bats in regenerating areas.
Echolocation calls of Myotis frater emitted during the search phase consist of brief frequency-modulated pulses. The sound signals are comprised of three harmonics of which the first one is of the highest intensity and occurs in all echolocation calls. The frequency of this fundamental harmonic ranges from 110.8 to 50.2 kHz, and its duration is about 3.5 ms. The second and the third harmonics are relatively weak, occurring in 50.0% and 25.0% of echolocation calls respectively, with frequencies ranging from 138.4 to 116.6 kHz for the second harmonic and from 193.6 to 170.8 kHz for the third harmonic. We presume that, according to the echolocation call features, Myotis frater probably forages the insects on the ground of complex environments.

We sequenced the mitochondrial cytochrome b, 12S rRNA and 16S rRNA genes from three insectivoran species (Japanese mole, shrew mole and musk shrew) and one chiropteran species(Japanese pipistrelles) and the cytochrome c oxidase subunit II (COII) gene from a chiropteran species. The phylogenetic relationship of core Insectivora or Eulipotyphla among major Eutherian orders was examined for these genes. A total evaluation of the maximum likelihood analyses of the four genes suggests that Chiropt...

We report the discovery of a new species of Lophostoma from Panama, which we name L. kalkoae. This new species resembles L. carrikeri and L. yasuni in possessing a white venter, but is distinguishable from both by external and cranial characteristics. The new species is similar in size to L. carrikeri and L. schulzi. Lophostoma sp. nov. can be most easily recognized by its combination of white venter, postauricular patches connected by a thin line of pale hair to the white fur on the chest, elongated clitoris and swollen labia, less strongly developed lateral projection of mastoid processes, well-marked indentation on the lingual cingulum of the upper canine, well-developed P3, well-developed posterior lingual cusp on the cingulum of P4, and parastyle absent on M1 and M2. We present a dichotomous key for the genus Lophostoma and a map showing all the localities where white-bellied Lophostoma have been recorded.

Full Text Available In temperate zones, insectivorous bats use some types of habitat more frequently than others, and are more active in the warmest periods of the year. We assessed the spatial and seasonal activity patterns of bats in open areas of the southernmost region of Brazil. We tested the hypothesis that bat activity differs among habitat types, among seasons, and is influenced by weather variables. We monitored four 1,500-m transects monthly, from April 2009 to March 2010. Transects corresponded to the five habitat types that predominate in the region. In each sampling session, we detected and counted bat passes with an ultrasound detector (Pettersson D230 and measured climatic variables at the transects. We recorded 1,183 bat passes, and observed the highest activity at the edge of a eucalyptus stand (0.64 bat passes/min and along an irrigation channel (0.54 bat passes/min. The second highest activity values (0.31 and 0.20 bat passes/min, respectively were obtained at the edge of a riparian forest and at the margin of a wetland. The grasslands were used significantly less (0.05 bat passes/min. Bat activity was significantly lower in the winter (0.21 bat passes/min and showed similar values in the autumn (0.33 bat passes/min, spring (0.26 bat passes/min, and summer (0.29 bat passes/min. Bat activity was correlated with temperature, but it was not correlated with wind speed and relative humidity of the air. Our data suggest that, in the study area, insectivorous bats are active throughout the year, and use mostly forest and watercourses areas. These habitat types should be considered prioritary for the conservation of bats in the southernmost region of Brazil.

There are two subspecies of Rhinolophus sinicus currently recognized in China. In this study, using next generation sequencing approaches, the complete mitochondrial genome of one subspecies R. s. sinicus was obtained. The total length of the genome sequence is 16,898 bp. The arrangement and contents of R. s. sinicus mitochondrial genes exhibit high similarity with other bats of family Rhinolophida. Phylogenetic reconstructions support the sister relationship of the two subspecies and confirm the subspecies status of our specimen. PMID:25740216

Vampyressa melissa is a poorly known phyllostomid bat listed as vulnerable by the International Union for Conservation of Nature (IUCN). Since its description in 1926, fewer than 40 V. melissa have been reported in the literature, and less than half of these may have been correctly identified. During revisionary studies of Vampyressa, we uncovered two previously unrecognized species related to V. melissa, all associated with higher elevation habitats (>1400 m), one from the Andes of Colombia (Vampyressa sinchi, new species) and the other from western Panama (Vampyressa elisabethae, new species) revealing that V. melissa, as traditionally defined, is a composite of at least three species. In this paper, we provide a restricted diagnosis for the genus Vampyressa, an emended diagnosis of V. melissa, and descriptions of the two new species. The separation of these frugivorous bats, previously identified as V. melissa, into three isolated upper-elevation species, each having restricted distributions further highlights their fragile conservation status.

In this article we report the complete mitochondrial genome of black flying fox, Pteropus alecto, with the sequence length of 16,739 bp for the first time. The mitogenome contained a total of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 1 control region. The base composition was A (33.1%), G (14.5%), C (27.2%) and T (25.2%), indicating that the percentage of A and T (58.3%) was higher than that of G and C. Most of these genes were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes. The mitochondrial genome analyzed here will provide new genetic information to study the evolution of bats. PMID:24438271

In the present study, I described the organization of a Neotropical bat assemblage, and tested whether this organization was variable in time. In an Atlantic Forest reserve in southeastern Brazil bats were captured monthly with mist nets over 4 years, and individuals were classified into guilds. I analyzed only leaf-nosed bats, and observed that guilds of fruit-eating bats dominated the assemblage. This pattern was repeated across months and years. However, among frugivores, canopy and understory guilds peaked during different months, but in both cases during the rainy season, while variation among habitat-opportunistic species was not explained by rainfall. The most reliable ecological service delivered by phyllostomid bats in the area is seed dispersal, although other services may be also important in particular seasons. My results suggest that the observed patterns of temporal species turnover are related to the abundance of preferred food items.
Full Text Available Frugivorous and nectarivorous bats fuel their metabolism mostly by using carbohydrates and allocate the restricted amounts of ingested proteins mainly for anabolic protein syntheses rather than for catabolic energy production. Thus, it is possible that genes involved in protein (amino acid catabolism may have undergone relaxed evolution in these fruit- and nectar-eating bats. The tyrosine aminotransferase (TAT, encoded by the Tat gene is the rate-limiting enzyme in the tyrosine catabolic pathway. To test whether the Tat gene has undergone relaxed evolution in the fruit- and nectar-eating bats, we obtained the Tat coding region from 20 bat species including four Old World fruit bats (Pteropodidae and two New World fruit bats (Phyllostomidae. Phylogenetic reconstructions revealed a gene tree in which all echolocating bats (including the New World fruit bats formed a monophyletic group. The phylogenetic conflict appears to stem from accelerated TAT protein sequence evolution in the Old World fruit bats. Our molecular evolutionary analyses confirmed a change in the selection pressure acting on Tat, which was likely caused by a relaxation of the evolutionary constraints on the Tat gene in the Old World fruit bats. Hepatic TAT activity assays showed that TAT activities in species of the Old World fruit bats are significantly lower than those of insectivorous bats and omnivorous mice, which was not caused by a change in TAT protein levels in the liver. Our study provides unambiguous evidence that the Tat gene has undergone relaxed evolution in the Old World fruit bats in response to changes in their metabolism due to the evolution of their special diet.

Full Text Available In the present study, we investigated the prevalence and intensity of Hectopsylla pulex infection in Molossus rufus and Molossus molossus, the parasite's choice of attachment site, and whether this host-parasite system varies with host size. Twenty-four bats were captured by hand from the roof of a house in Southeastern Brazil. M. rufus exhibited a prevalence of 71.4% and the mean intensity averaged 5 ectoparasites per bat. M. molossus exhibited a prevalence of 90%, and the average mean intensity was 2.11 ectoparasites. The attachment sites were: ear, tragus, shoulder blade and tibia, anus, wing, axilla, mouth and dactylopatagium. A positive correlation was observed between the bats' weight and the number of fleas.

Examination of 135 specimens representing 21 species from seven genera of the family Molossidae revealed diploid numbers ranging from 34 to 48. Seventeen species from six genera have diploid numbers of 48. Geographic variation and polymorphism were found only in Eumops glaucinus. Chromosomal variation within the family is presumed to be primarily due to changes in diploid number resulting from Robertsonian translocations.

Full Text Available Tadarida brasiliensis (Geoffroy, 1824, the Brazilian free-tailed bat, is an insectivorous bat that occurs from southern United States of America to southern South America. In this study we present the first data on diversity of ectoparasitic mites of T. brasiliensis in Brazil. A compilation and analysis of the studies of mite diversity conducted in different points the geographic distribution this bat species are provided. The mites were collected from March 2010 to November 2011 on 160 T. brasiliensis adult bats captured in southern Brazil. Four species of mites have been found: Chiroptonyssus robustipes (Ewing, 1925, Ewingana longa (Ewing, 1938, Ewingana inaequalis (Radford, 1948, and specimens of Cheyletidae. Chiroptonyssus robustipes was the most prevalent species (100%, followed by E. longa (20%, E. inaequalis (10%, and specimens of Cheyletidae (1.25%. The data currently available show that C. robustipes parasitizes T. brasiliensis throughout its region of occurrence, and this mite is highly prevalent and abundant. The two species of Ewingana accompany the geographical distribution of T. brasiliensis, but with much lower prevalence and abundance.

Full Text Available In mitochondrial DNA, variations in the sequence of 16S rRNA region were analyzed to infer the genetic relationship and population history of three sympatric hipposiderid bats, Hipposideros speoris, H. fulvus and H. ater. Based on the DNA sequence data, we observed relatively lower haplotype and higher nucleotide diversity in H. speoris than in the other two species. The pairwise comparisons of the genetic divergence inferred a genetic relationship between the three hipposiderid bats. We used haplotype sequences to construct a phylogenetic tree. Maximum parsimony and Bayesian inference analysis generated a tree with similar topology. H. fulvus and H. ater formed one cluster and H. speoris formed another cluster. Analysis of the demographic history of populations using Jajima’s D test revealed past changes in populations. Comparison of the observed distribution of pairwise differences in the nucleotides with expected sudden expansion model accepts for H. fulvus and H. ater but not for H. speoris populations.

Full Text Available Some bat species seem to be lunar phobic, i.e., they avoid flying in bright areas or during bright periods of the night; however, the evidence is still controversial. We think that part of this controversy comes from pooling data on bat captures and moonlight intensity according to broad categories, such as moon phases, which conceal the high variability among nights. Therefore, we used detailed, long-term field data on three phyllostomid bat species, in order to test the hypothesis of lunar phobia at two different time scales: 1 among nights, by pooling data of different nights according to moon phases and testing for differences in the distribution of captures; and 2 within a night, by analyzing the relationship between capturability and moonlight intensity (measured as illuminance in one-hour intervals for 29 individual nights. Although most captures of the studied bat species occurred in the first half of the night, their activity pattern varied largely among nights, and was not always unimodal as commonly assumed. At the larger time scale, all studied bat species showed evidence of lunar phobia, as they were more frequently captured on dark moon phases. Nevertheless, at the smaller time scale, only Carollia perspicillata (Linnaeus, 1758 was less frequently captured on brighter periods of the night. We propose that the unimodal activity pattern assumed for frugivorous phyllostomid bats may be an artifact of data organization, and that activity and lunar phobia are much more variable than previously assumed.

Bats are a highly successful, widely distributed group, with considerable variation in placental structure. The Egyptian slit-faced bat Nycteris thebaica is a member of one of the few families with previously undescribed placentation. It was found that, although the interhemal type of the Nycteris...... placenta is endotheliochorial with a single layer of cytotrophoblast, the arborizing pattern of the maternal vessels and especially the extraordinary major placental artery differs from the placenta of the emballonurid bats to which this family is considered to be most closely related. The major placental...... other bat species. The paraplacenta is extensive with abundant fetal vessels underlying cytotrophoblast and syncytial trophoblast layers, fronting on an endometrium that largely lacks uterine epithelial cells but has large decidual cells and is poorly vascularized. The placenta of Nycteris lacks a...

Full Text Available Rabies virus was detected in bats (Molossus molossus from an urban area in the City of Recife, State of Pernambuco, Brazil. Four individuals were found during the day in visible, non-habitual places, lying on the ground, but still alive. No contact occurred with people or animals. Of these, only two were identified; it was not possible to identify two specimens, since they were incinerated prior to identification. Diagnosis was positive by direct immunofluorescence and intracerebral inoculation in mice. This study presents the first instance in which the virus was detected in insectivorous bats in the State of Pernambuco.
Full Text Available The diet, activity and reproductive patterns of several species of bats were investigated in primary forests of Central Amazon. Between August 1996 and August 1997, using mist nets set both at canopy and understorey levels, 936 bats, belonging to 51 species, 31 genera and 6 families were captured. Fecal samples from 35 species were examined, with four food categories and 25 food items identified. Time of captures indicate a wide variation, but the major part of the species presented a peak of activity around the first hour after sunset. Three reproductive peaks were observed: October-November; January-February; and July-August, but reproductive patterns varied among the families. The structure of the bat fauna in Manaus is similar to other sites in the Amazon and Central America, the main common points being: a a high diversity of bat species, usually more than 40 species representing 6-8 families; b 3-4 very common and geographically widespread species; c most species are represented by a few captures; d frugivorous species dominate the fauna and insectivorous species are less often captured; and e most species cluster in 2-3 guilds, dominated by small (< 12 g species.

Full Text Available Phenotypes of distantly related species may converge through adaptation to similar habitats and/or because they share biological constraints that limit the phenotypic variants produced. A common theme in bats is the sympatric occurrence of cryptic species that are convergent in morphology but divergent in echolocation frequency, suggesting that echolocation may facilitate niche partitioning, reducing competition. If so, allopatric populations freed from competition, could converge in both morphology and echolocation provided they occupy similar niches or share biological constraints. We investigated the evolutionary history of a widely distributed African horseshoe bat, Rhinolophus darlingi, in the context of phenotypic convergence. We used phylogenetic inference to identify and date lineage divergence together with phenotypic comparisons and ecological niche modelling to identify morphological and geographical correlates of those lineages. Our results indicate that R. darlingi is paraphyletic, the eastern and western parts of its distribution forming two distinct non-sister lineages that diverged ~9.7 Mya. We retain R. darlingi for the eastern lineage and argue that the western lineage, currently the sub-species R. d. damarensis, should be elevated to full species status. R. damarensis comprises two lineages that diverged ~5 Mya. Our findings concur with patterns of divergence of other co-distributed taxa which are associated with increased regional aridification between 7-5 Mya suggesting possible vicariant evolution. The morphology and echolocation calls of R. darlingi and R. damarensis are convergent despite occupying different biomes. This suggests that adaptation to similar habitats is not responsible for the convergence. Furthermore, R. darlingi forms part of a clade comprising species that are bigger and echolocate at lower frequencies than R. darlingi, suggesting that biological constraints are unlikely to have influenced the convergence. Instead, the striking similarity in morphology and sensory biology are probably the result of neutral evolutionary processes, resulting in the independent evolution of similar phenotypes.

Full Text Available The genus Rhinophylla Peters, 1865 (Carolliinae: Phyllostomidae comprises three species: R. pumilio Peters, 1865, R. fischerae Carter, 1966 and R. alethina Handley, 1966. Only the first two species have been cytogenetically studied to date. Previous studies on specimens of Rhinophylla fischerae from two populations from East of Andes (Colombia showed the karyotype with 2n=34 and FN=56. In this paper, we report the results of cytogenetic analysis of six specimens of Rhinophylla fischerae from Brazil. Probably chromosomal differences can be found among the populations because of the geographic distance. Metaphase chromosomes were obtained in the field by direct extraction of bone marrow. The metaphases were analyzed by conventional staining, G- and C-banding, NOR-staining and FISH with telomeric probes. Rhinophylla fischerae has 2n=38 and Fundamental Number FN=68, with small amounts of constitutive heterochromatin in the centromeric regions of the chromosomes and the long arm of pair 16. Fluorescence in situ hybridization using telomeric probes did not show any interstitial sequences. Hybridization with human 18S and 28S rDNA probes and silver staining revealed the presence of Nucleolar Organizer Regions at the long arms of pairs 16 and 18. The pattern of G-banding showed that this population had a huge chromosome variation compared with previous studies on specimens of Rhinophylla fischerae. The chromosomal differences among populations that have been morphologically classified as R. fischerae suggest that this species should be considered a cryptic species complex, and that the populations from different geographical regions analyzed to date should be considered species of this complex, where the chromosomal rearrangements had key importance.

A new species of nematode, Torrestrongylus tetradorsalis n. sp., is described herein, based on specimens recovered from the small intestine of the leaf-nosed bat, Macrotus waterhousii, from the Biosphere Reserve “Sierra de Huautla” in the state of Morelos, Mexico. The new species is included in Torrestrongylus because it features a bursa of the type 3 – 2, a divided cephalic vesicle with an anterior half in the shape of an umbrella, and a posterior widened half. The new species can be distinguished from the only other congener T. torrei Pérez-Vigueras, 1935 by four key features: first, by the absence of cervical alae in both males and females; second, by the relatively longer second half of the cephalic cap; third, by the configuration of the dorsal ray, that does not have a medial terminal ray, and finally, by the structure of the spicules. This is the second species in the genus, previously known from bats of the families Phyllostomidae and Molossidae in Cuba, and now in Mexico. PMID:26514594

We studied infestation rates and parasite-host associations between streblid flies and phyllostomid bats in an Atlantic Forest area of Rio de Janeiro state, southeastern Brazil. We captured 301 individuals from seven Phyllostomidae bat species. Out of that total, 69 bats had been parasitised by nine Streblidae species; the most frequent species were Trichobius joblingi and Trichobius tiptoni. The species Paraeuctenodes longipes, associated with Anoura geoffroyi, was the most frequent species. The highest mean intensity was observed for Paraeuctenodes longipes, associated with A. geoffroyi, and Paratrichobius longicrus associated with Artibeus lituratus, both ectoparasite species with a mean intensity of five individuals per bat. Trichobius joblingi exhibited the highest mean abundance, which was over three on its host species. Streblid richness in the study area was similar to the richness found in other studies carried out in the Atlantic Forest. We observed that streblid richness in this biome depends more on inherent characteristics of each physiognomy and on the host-species than on the sampling effort. PMID:24789402

Hace algún tiempo el doctor Jorge Boshell Manrique capturó un ejemplar de murciélago del género Diclidurus cuyos caracteres indican que aparentemente corresponde a una especie previamente no descrita. Por primera vez se registra así la presencia de este género en Colombia, del cual se reconocen actualmente otras dos especies: D. albus (1), cuya distribución conocida comprende las Guayanas y el Brasil (Estados de Amazonas, Baía y Espirito Santo), y D. virgo (2) repartida a través de Guatemala...

Abstract Bats were censused in the Adamello-Brenta Natural Park (Trentino, central Italian Alps) in May-September 1999 and 2000, by mist-netting and roost surveys. In all, 90 sites (19 caves, 50 buildings and 21 foraging sites), over an area of about 618 km², were checked. The bat species distribution in both the Park and the surrounding areas was obtained by using field data, museum records and literature information. A total of 19 species was recorded:...
Full Text Available Abstract Bats were censused in the Adamello-Brenta Natural Park (Trentino, central Italian Alps in May-September 1999 and 2000, by mist-netting and roost surveys. In all, 90 sites (19 caves, 50 buildings and 21 foraging sites, over an area of about 618 km², were checked. The bat species distribution in both the Park and the surrounding areas was obtained by using field data, museum records and literature information. A total of 19 species was recorded: of these, one (Myotis bechsteinii was known from a museum collection and 18 were recorded in the field (Rhinolophus ferrumequinum, R. hipposideros, Myotis blythii, M. daubentonii, M. emarginatus, M. mystacinus, M. nattereri, Pipistrellus kuhlii, P. nathusii, P. pipistrellus, Nyctalus leisleri, Hypsugo savii, Eptesicus nilssonii, E. serotinus, Vespertilio murinus, Barbastella barbastellus, Plecotus alpinus, P. auritus. Local distribution, habitat use and body size parameters of the species were studied, and selection of roosts and foraging sites by the bat community was analysed with logistic regression. The conservation status of the bat community is also discussed. We document the third record of breeding by Pipistrellus nathusii and the fourth Eptesicus (Amblyotus nilssonii nursery in Italy, as well as the first roosting sites of the recently described Plecotus alpinus. Riassunto Comunità di Chirotteri e status delle popolazioni nel Parco Naturale Adamello-Brenta (Trentino-Alto Adige Vengono presentati i risultati di una serie di monitoraggi, effettuati con tecniche differenti (principalmente catture con reti mist-net ed esplorazione dei siti di rifugio dal 1999 al 2000. Tali indagini hanno permesso di raccogliere dati originali sulla distribuzione e sullo status della chirotterofauna, ai quali sono state affiancate ulteriori informazioni derivanti dalla letteratura recente e da studi di collezioni museali, al fine di definire un quadro di sintesi aggiornato ed esaustivo della distribuzione dei Chirotteri nel Parco Naturale Adamello-Brenta (Trentino-Alto Adige. Complessivamente sono stati esaminati distribuzione e status di 19 specie tra cui 18 (Rhinolophus ferrumequinum, R. hipposideros, Myotis blythii, M. daubentonii, M. emarginatus, M. mystacinus, M. nattereri, Pipistrellus kuhlii, P. nathusii, P. pipistrellus, Nyctalus leisleri, Hypsugo savii, Eptesicus nilssonii, E. serotinus, Vespertilio murinus, Barbastella barbastellus, Plecotus alpinus, P. auritus rilevate direttamente mediante il monitoraggio di 90 siti (19 grotte, 50 edifici e 21 stazioni di cattura in campo aperto rappresentativi di una superficie complessiva di circa 618 km², ed una, Myotis bechsteinii, rilevata da informazioni derivanti da collezioni museali. Vengono presentate informazioni concernenti il quadro distributivo locale, la selezione dell'habitat ed alcuni parametri biometrici per la comunità di chirotteri del Parco. Vengono inoltre esposte considerazioni su status e conservazione delle specie nell'area esaminata. In aggiunta, vengono riportate: la terza segnalazione per l'Italia di riproduzione di Pipistrellus nathusii, la quarta colonia riproduttiva nota per l'Italia di Eptesicus (Amblyotus nilssonii e la prima segnalazione di colonie della nuova specie Plecotus alpinus.
