Kinship, association, and social complexity in bats
Among mammals, bats exhibit extreme variation in sociality, with some species living largely solitary lives while others form colonies of more than a million individuals. Some tropical species form groups during the day ...
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), ...
Social communication in bats
Bats represent one of the most diverse mammalian orders, not only in terms of species numbers, but also in their ecology and life histories. Many species are known to use ephemeral and/or unpredictable resources that require ...
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, ...
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 ...
Repeatability in the contact calling system of Spix's disc-winged bat (Thyroptera tricolor)
Spix's disc-winged bat (Thyroptera tricolor) forms cohesive groups despite using an extremely ephemeral roost, partly due to the use of two acoustic signals that help individuals locate roost sites and group embers. While ...
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, ...
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 ...
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 ...
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 ...
