The importance of group vocal behaviour in roost finding
Individuals benefit from socially acquired information to avoid predation risks and enhance foraging efficiency. Spix's disc-winged bats, Thyroptera tricolor, form very stable social groups despite their need to find a new ...
Unveiling the Hidden Bat Diversity of a Neotropical Montane Forest
Mountain environments, characterized by high levels of endemism, are at risk of experiencing significant biodiversity loss due to current trends in global warming. While many acknowledge their importance and vulnerability, ...
Contrasting Thermal Strategies of Montane Neotropical Bats at High Elevations
In the Neotropics, captive vespertilionid bats substantially reduce their metabolic rate at low ambient temperatures, similar to their temperate counterparts, whereas the ability of phyllostomids to lower metabolic rate ...
When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor
For species characterized by philopatry of both sexes, mate selection represents an important behaviour for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here, we present evidence of male ...
Sound amplification by means of a horn-like roosting structure in Spix's disc-winged bat
While sound is a signal modality widely used by many animals, it is very susceptible to attenuation, hampering effective long-distance communication. A strategy to minimize sound attenuation that has been historically used ...
MURCIÉLAGOS de la región del Golfo Dulce, Puntarenas, Costa Rica
BATS of the Golfo Dulce Region, Costa Rica - Field Guides
La región del Golfo Dulce está compuesta de bosque estacionalmente húmedo primario y secundario. Esta guía incluye especies representativas de las familias presentes en las tierras bajas de la región (< de 400 m.s.n.m), ...
Variation in echolocation call frequencies in two species of free-tailed bats according to temperature and humidity
Bats can actively adjust their echolocation signals to specific habitats and tasks, yet it is not known if bats also modify their calls to decrease atmospheric attenuation. Here the authors test the hypothesis that individuals ...
Comparing the efficiency of monofilament and traditional nets for capturing bats
Traditional mist nets used for capturing bats have several drawbacks, particularly that they are inefficient at sampling many insectivorous species. One possible alternative is to use monofilament nets, whose netting is ...
Ontogeny of an interactive call-and-response system in Spix's disc-winged bats
We investigated the ontogenetic changes of two call types, the inquiry call and the response call, which comprise an interactive communication system in Spix's disc-winged bats, Thyroptera tricolor. We documented structural ...
Effects of roost specialization on extinction risk in bats
Los Efectos de la Especializacion de Dormidero sobre el Riesgo de Extinción de Murciélagos
Understanding causes and consequences of ecological specialization is of major concern in conservation. Specialist species are particularly vulnerable to human activities. If their food or habitats are depleted or lost, ...
