Ontogeny of an interactive call-and-response system in Spix's disc-winged bats
(2020)
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 ...
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 ...
Contrasting Thermal Strategies of Montane Neotropical Bats at High Elevations
(2018)
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 ...
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, ...
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 ...
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 ...
All-offspring natal philopatry in a Neotropical bat
(2011-11)
Natal dispersal is a strategy employed by individuals to avoid reproducing with close relatives. In most
bats, incestuous matings are prevented by the departure of one sex; thus, all-offspring philopatry has
rarely been ...
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 ...
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 ...
