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), ...
Contact calling in context: intra- and intergroup variation in vocalization rates depend on a call’s function
To maintain group cohesion while coordinating group movements, individuals might use signals to advertise the location of a route, their intention to initiate movements, or their position at a given time. In highly mobile ...
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 ...
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 ...
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, ...
