Bats mimic hymenopteran insect sounds to deter predators
(2022)
This study explores interspecific acoustic mimicry in mammals, particularly focusing on the greater mouse-eared bat (Myotis myotis) distress calls. These calls imitate stinging bee and wasp sounds, aiming to deter avian ...
Kinship, association, and social complexity in bats
(2019-01)
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 ...
Effects of roost specialization on extinction risk in bats
Los Efectos de la Especializacion de Dormidero sobre el Riesgo de Extinción de Murciélagos
(2015)
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, ...

BATS of the Golfo Dulce Region, Costa Rica - Field Guides
(2019-11-18)
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
(2017)
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 ...
The importance of group vocal behaviour in roost finding
(2018)
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 ...
Range overlap and association patterns in the tent-making bat Artibeus watsoni
(2007)
Space use and ranging patterns of individuals have traditionally been used to identify social systems, and the amount of overlap in the home ranges of individuals can provide indirect information about the likelihood of ...
Comparing the efficiency of monofilament and traditional nets for capturing bats
(2021)
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 ...
Social communication in bats
(2018)
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
(2016-10)
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, ...
