When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor
(2013-11)
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 ...
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, ...
Sound amplification by means of a horn-like roosting structure in Spix's disc-winged bat
(2013-10)
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 ...
Contact calling in context: intra- and intergroup variation in vocalization rates depend on a call’s function
(2020)
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 ...
Repeatability in the contact calling system of Spix's disc-winged bat (Thyroptera tricolor)
(2015-01)
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 ...
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)
Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may
disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ...
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 ...
Bat Assemblages along an Elevational Gradient in Costa Rica
(2022)
Spatio-temporal patterns of species richness, Hill numbers, captures per species, feeding guilds, sex ratio, and biomass were studied
in a Neotropical bat assemblage during 17 continuous months in four bands (low: 50–150, ...
A call-and-response system facilitates group cohesion among disc-winged bats
(2013)
Acoustic signals are important in maintaining group cohesion, particularly in highly mobile species. For these signals to facilitate group cohesion, individuals must be able to recognize, and respond to, calls emitted by ...
Spatio‑temporal distribution and reproductive phenologyof Neotropical bat species in an altitudinal gradient in Costa Rica
(2022-01-14)
We studied the altitudinal and temporal patterns of species abundance and reproductive status for 18 Neotropical bat species
during 17 continuous months in four ranges (low 50, mid–low 500, mid–high 1000, and high 2000 ...
