Abstract: bats (chiroptera: mammalia) from yurubí national park, venezuela: taxonomic list and community study. 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. rev. biol. trop. 59 (4): 1757-1776. epub 2011 december 01.

Abstract: Los murciélagos constituyen el grupo de mamíferos más diversificado en la región neotropical y representan un componente clave en la dinámica de muchos ecosistemas terrestres. En este trabajo se describen los resultados de un estudio sobre la quiropterofauna del Parque Nacional Yurubí (ubicado en la zona monta osa del norte de Venezuela), se incluye un listado taxonómico y la caracterización de algunos atributos comunitarios en ambientes predominantemente boscosos. Los datos evaluados fueron obtenidos mediante la revisión de colecciones zoológicas y muestreos diversificados realizados entre febrero y julio del 2009, en un gradiente altitudinal (100-1 500m), que integra a tres unidades ecológicas: bosque semideciduo, bosque siempreverde y selva nublada. Se registraron 64 especies agrupadas en cinco familias, lo que constituye el 63% de los murciélagos conocidos en la Cordillera de la Costa. La familia Phyllostomidae fue dominante (42 especies; 66% del total), seguida por Vespertilionidae, Molossidae, Emballonuridae y Mormoopidae. La comunidad presente a baja elevación fue la más diversificada en términos taxonómicos, mientras que la del piso superior evidenció el menor grado de diversificación. Se identificaron 11 categorías tróficas, con dominancia de los insectívoros en cuanto a la riqueza taxonómica y de los frugívoros en lo que respecta a la abundancia. Nuestros resultados permiten inferir, en un contexto general, que los ecosistemas boscosos del área de estudio muestran un buen estado de conservación, en virtud de la presencia de una proporción relativamente alta de especies pertenecientes a la subfamilia Phyllostominae, cuyos componentes han sido considerados por otros autores como indicadores del grado de conservación de hábitats boscosos primarios, así como la presencia de otras especies con prioridades de conservación. Todos estos aspectos, le confieren a esta área protegida un alto valor proteccionista, en virtud de su importancia como reservorio de la diversidad biológica que tipifica los ecosistemas boscosos de la Cordillera de la Costa, una bio-región altamente amenazada como consecuencia de un elevado crecimiento socio-económico.

Estudios Geologicos , 1986,
Abstract: The Chiroptera from Escobosa de Calata azor (Soria, Spain), an Upper Aragonian karstic site, are described in this report. The faunal list of Chiroptera is as follows: Megaderma gaillardi, Rhinolophus grivensis, Rhinolophus delphinensis and one chiropter, indeterminate family, different to the mentioned species. This fauna is typical of karstic sites and allows to compare it with those of other sites of the Miocene and Pliocene of west Europe and north Africa. Se describen en este trabajo los quirópteros del yacimiento kárstico del Aragoniense superior de Escobosa de Calata azor (prov. de Soria, Espa a). La fauna de quirópteros es la siguiente: Megaderma gaillardi, Rhinolophus grivensis, Rhinolophus delphinensis y un quiróptero, familia indeterminada, distinto de las especies mencionadas. Esta fauna, característica de yacimiento kárstico, permite su comparación con las de otros yacimientos del Mioceno y Plioceno de Europa occidental y norte de Africa.

Check List , 2010,
Abstract: We report new records for 254 specimens of 19 species of bats from 15 genera and three of the four families ofArgentine bats (Phyllostomidae, Vespertilionidae, and Molossidae). Sixty one new distributional records were also addedto eight provinces of Argentina and to the Puna, Monte of mountains and valleys, Yungas forests, Dry and Humid Chaco,Pampas, Fields and Weedlands, and Paranean forests ecoregions. We add only one new bat species to an ecoregion: the firstreport of Promops nasutus for the Monte of mountains and valleys

Abstract: patterns of parasite abundance and prevalence are thought to be influenced by several host characteristics such as size, sex, developmental stage, and seasonality. we examined two obligatory ectoparasites of the bat noctilio leporinus (l.) (chiroptera, noctilionidae) to test whether prevalence and abundance of noctiliostrebla aitkeni wenzel and paradyschiria fusca speiser (diptera, streblidae) are influenced by the host characteristics. during this survey, 2110 flies were collected. the total abundance was 1150 n. aitkeni and 950 p. fusca. the prevalence of both species was shown to be superior to 75% and neither host size, sex, reproductive stage nor season influenced significantly the variation of the observed values. n. aitkeni were more abundant than p. fusca in all seasons except winter. both flies showed a significant seasonal variation in terms of abundance but host biological characteristics (host size, sex, and reproductive stage) did not play a significant role as structuring factors of the batflies component community.

Abstract: the order chiroptera plays a vital role in ecosystem dynamics. among the states of southeastern brazil, espírito santo state is the one with the least known bat fauna. this study reports on the current state of knowledge on espírito santo bats generating this data bank. we have catalogued the bats deposited in the biology museum prof. mello leit?o (mbml), laboratory of bat studies of the federal university of espírito santo (labeq), museum of vertebrate zoology (mvz), royal ontario museum (rom), american museum of natural history (amnh), and university of michigan museum of zoology (ummz). in addition, we have investigated the literature seeking articles about bats exclusively for the state. about bats were published in the state 42 papers, three thesis and 11 monographs. there are recognized 63 bat species in the state, if considering the museum collections and published papers, from 37 of the 78 municipalities of espírito santo. the highest species richness was found in the municipalities of linhares and santa teresa. this was probably occasioned by bias on sampling. the great potential for new bat occurrences in espírito santo is due to the lack of knowledge about bats in this state. this emphasizes the importance for new future studies about bats in that area.
Palinofagia de los murcielagos del genero Glossophaga (Mammalia: Chiroptera) en México
Nansy Sánchez Casas,Ticul Alvarez
Acta zoológica mexicana , 2000,
Abstract: El estudio se basó en el análisis de 1012 contenidos gastrointestinales de murciélagos representando las cuatro especies del género Glossophaga (Mammalia:Phyllostomidae) que se distribuyen en México. El análisis consistió en el procesamiento, identificación y cuantificación de los granos de polen extraídos de los tractos digestivos. Se identificaron 36 especies de plantas utilizadas como parte de la alimentación, siendo en general las más importantes por su abundancia: Mastichodendron capiri, Crescentia alata, Pseudobombax ellipticum, Cordia alliodora, Pithecellobium lanceolatum, Ipomoea sp. y Bursera sp. Se encontraron variaciones significativas entre la alimentación de las hembras y la de los machos, así como estacional y geográfica. Glossophaga soricina fue la especie en la cual se encontró la mayor variedad de plantas, por esto y por ser la de mayor distribución en la República Mexicana es considerada la especie más oportunista del género en nuestro país. Finalmente se discute que el traslapo encontrado en la dieta, no necesariamente es un indicador de uso común de recursos.
Molecules, morphometrics and new fossils provide an integrated view of the evolutionary history of Rhinopomatidae (Mammalia: Chiroptera)

BMC Evolutionary Biology , 2007, DOI: 10.1186/1471-2148-7-165
Abstract: Here we present (a) a phylogenetic analysis based on a partial cytochrome b sequence, (b) new fossils from the Upper Miocene site Elaiochoria 2 (Chalkidiki, Greece), which represents the first appearance datum of the family based on the fossil record, and (c) discussion of the phylogeographic patterns in both molecular and morphological traits. We found deep divergences in the Rhinopoma hardwickii lineage, suggesting that the allopatric populations in (i) Iran and (ii) North Africa and the Middle East should have separate species status. The latter species (R. cystops) exhibits a shallow pattern of isolation by distance (separating the Middle East and the African populations) that contrasts with the pattern of geographic variation in the morphometrical traits. A deep genetic gap was also found in Rhinopoma muscatellum (Iran vs. Yemen). We found only minute genetic distance between R. microphyllum from the Levant and India, which fails to support the sub/species distinctness of the Indian form (R. microphyllum kinneari).The mtDNA survey provided phylogenetic tree of the family Rhinopomatidae for the first time and revealed an unexpected diversification of the group both within R. hardwickii and R. muscatellum morphospecies. The paleobiogeographic scenario compiled in respect to molecular clock data suggests that the family originated in the region south of the Eocene Western Tethyan seaway or in India, and extended its range during the Early Miocene. The fossil record suggests a Miocene spread into the Mediterranean region, followed by a post-Miocene retreat. Morphological analysis compared with genetic data indicates considerable phenotypic plasticity in this group.The mammalian order Chiroptera serves as an excellent example of how molecular phylogenetics has influenced the taxonomy of a seemingly well resolved group. Genetic data invalidated the traditional subdivision of bats into suborders Megachiroptera and Microchiroptera when Teeling et al. [1-3] provided mol
