Although the geographical distribution of the free-tailed bat, Nyctinomops laticaudatus (Chiroptera, Molossidae), is well documented, it presents discontinuities that may be caused by insufficient sampling or misidentified specimens. These geographical distribution gaps can hamper the interpretation of the effects of anthropic impacts on this speci...

Bat pollination at the range margin in the southwestern Neotropics has been largely unexplored. We provide for the first time direct evidence on bat pollination, visitation rate, and efficiency for three species of the Southern Andean Yungas. These interactions are valuable targets for future conservation efforts in this endangered ecosystem. Abstr...

Bats are reservoirs of various coronaviruses that can jump between bat species or other mammalian hosts, including humans. This article explores coronavirus infection in three bat species ( Tadarida brasiliensis, Eumops bonariensis , and Molossus molossus ) of the family Molossidae from Argentina using whole viral metagenome analysis. Fecal samples...

As currently understood, the genus Nyctinomops contains four species: N. aurispinosus (Peale, 1849), N. femorosaccus (Merriam, 1889), N. laticaudatus (É. Geoffroy St.-Hilaire, 1805), and N. macrotis (Gray, 1840). Only N. macrotis and N. laticaudatus have been recorded from Argentina. We found that specimens of Nyctinomops captured in the province o...

Breeding seasons in anurans are usually noticed by their advertisement calls, which stand as the main signal emitted by males during their adult life. These calls are species-specific signals with multiple information and can be used to monitor anuran populations over extended time periods. Applying a Passive Acoustic Monitoring method (PAM), we de...

The South American hoary bat, Lasiurus villosissimus (É. Geoffroy Saint-Hilaire, 1806), is a vespertilionid bat, endemic to South America and occurring in all countries except Guyana, French Guiana, and Suriname. It is one of the four species included in the subgenus Aeorestes. Lasiurus villosissimus is distinguishable from all other species of th...

RESUMEN. La dieta de la lechucita vizcachera (Athene cunicularia) es conocida gracias a numerosos estudios de sus egagrópilas. Entre los ítems alimenticios registrados, los quirópteros suelen ser muy poco frecuentes. En esta nota se describe una nueva especie de murciélago como presa de esta estrigiforme. Se trata del murciélago Myotis nigricans, d...

Ctenomys is one of the most speciose genera among South American rodents, whose systematics have not yet been fully elucidated. One of the difficulties for clarifying the identity of its species is the limited information available on some of them, erected more than a century ago and of which only the original descriptions are known, generally very...

Soundscapes are composed by the conjunction of sound patterns in each space and time. The biophony produced by the advertisement calls of anurans are one of the most outstanding features of a soundscape, particularly in subtropical montane areas such as the Yungas Andean forests of NW Argentina. We recorded soundscapes with automated recording unit...

In this research we explore elevation gradient of small mammal diversity on the arid slopes of the Andes in northwestern Argentina. We evaluated the influence of climatic and environmental factors on species richness and abundance across two altitudinal transects between 2700 and 4700 m. We used canonical correspondence analysis, multiple regressio...

Los límites más australes conocidos para la distribución de Noctilio albiventris se encuentran en Argentina, donde se consideraba que la especie habitaba exclusivamente en la región noreste del país. Recientemente, un ejemplar fue citado para el noroeste de Argentina, pero la localidad ha sido erróneamente definida. Este espécimen de referencia se...

Decadencia, olvido o intereses científicos? La osteología en murciélagos como estudio de caso Gaudioso et al. 2021 Resumen Los estudios de anatomía clásica, realizados durante la primera mitad del siglo XIX, contribuyeron al desarrollo de la teoría darwiniana de la evolución. En esa época surgieron los primeros trabajos descriptivos sobre el sistem...

Rufous-throated dipper (Cinclus schulzii) is the least known dipper, categorized as 'Vulnerable' by IUCN. From the year 2010 to 2013, we surveyed two mountain rivers in the Southern Yungas of Argentina to determine the abundance of this dipper in the breeding and non-breeding season. The overall relative abundance on the breeding season was 1.26 ±...

A new material of a Quaternary waterfowl is described here. The implications of this finding, in the context of the dispersal of Anatidae in the past, are discussed.

Fourteen species of bats in the genus Molossus currently are recognized in the Neotropical region; only three are known from Argentina. Here, we describe a new species based on specimens collected in the province of Santa Fe, Argentina, in the Pampa ecoregion. The new species can be distinguished from its congeners by its general strong orange colo...

Identifying adequate methods and tools for biodiversity monitoring is fundamental in ecology and conservation biology. Most of the standardised monitoring techniques involve the presence of the researchers at the survey sites meanwhile, passive acoustic monitoring (PAM) of the diversity of anuran species could be a valid alternative. In this study,...

Bats provide important ecosystem services as pollinators, seed dispersers, and/or insect controllers, but they have also been found harboring different viruses with zoonotic potential. Virome studies in bats distributed in Asia, Africa, Europe, and North America have increased dramatically over the past decade, whereas information on viruses infect...

Los murciélagos constituyen uno de los grupos más diversos de mamíferos, lo que se ve reflejado en su morfología y en su ecología, siendo el esqueleto postcraneal un ejemplo claro de esa diversificación (Arita y Fenton, 1997; Freeman, 2000). Si bien la anatomía del postcráneo de los murciélagos viene siendo estudiada desde la primera mitad del sigl...

En esta guía se actualizan e incrementan las distribuciones de muchas especies, incluyendo extensiones de especies a nuevas provincias, como resultados de un aumento muy significativo de muestreos de campo e incorporación de ejemplares en las colecciones sistemáticas (Barquez et al. 2011 a, b, 2013; Bracamonte y Lutz 2013; Castilla et al. 2010, 20...

Migratory colonies of up to thousands or millions of Brazilian free-tailed bats (Tadarida brasiliensis) are present in temperate areas of America. The monitoring of these massive colonies is crucial to know their conservation status and to evaluate the important ecosystem services that they provide.
