Vocal behavior and the use of social information during roost finding
(2022-07-26)
When selecting feeding, hiding, or resting areas, animals face multiple
decisions with different fitness consequences. To maximize efficiency,
individuals can either collect personal information, or use information
gathered ...
Evaluación del papel del sexo y las etapas reproductivas en los procesos de comunicación acústica en el murciélago de ventosas thyroptera tricolor (Chiroptera: thyropteridae)
(2022)
El comportamiento es uno de los rasgos más variables dentro del reino animal. Sin embargo, aún hay poca claridad sobre cuáles son los factores que inciden en su variabilidad. En muchas especies se sabe que con el inicio ...
Ecological Correlates of Roost Fidelity in the Tent-Making Bat Artibeus watsoni
(2007-05)
Roost switching is a common occurrence in bats, yet the causes and consequences of such behavior are poorly understood. In this study we explore the ecological correlates of roost fidelity in the tent‐making bat Artibeus ...
Ecological Correlates of Range Size in the Tent-Making Bat Artibeus watsoni
(2007-04)
We examined variation in foraging- and roosting-range size in the tent-making bat Artibeus watsoni. We radiotracked 42 individuals at 2 sites in the Golfito Wildlife Refuge and 6 sites at Corcovado National Park, southwestern ...
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 ...
Social Calls Produced within and near the Roost in Two Species of Tent-Making Bats, Dermanura watsoni and Ectophylla alba
(2013-04)
Social animals regularly face the problem of relocating conspecifics when separated. Communication is one of the most important mechanisms facilitating group formation and cohesion. Known as contact calls, signals exchanged ...
Response of a Specialist Bat to the Loss of a Critical Resource
(2011-12)
Human activities have negatively impacted many species, particularly those with unique traits that restrict their use of resources and conditions to specific habitats. Unfortunately, few studies have been able to isolate ...
Seasonality in the emission of contact calls in Spix’s disc-winged bats(Thyroptera tricolor) suggests a potential role in mate attraction
(2022)
Multiple studies show that animals exhibit consistent individual differences in behavior, but they also experience short-term changes
in their behavioral responses associated with seasonal events, most notably reproduction. ...
Strong individual signatures and weaker group signatures in contact calls of Spix’s disc-winged bat, Thyroptera tricolor
(2012-01)
Spix’s disc-winged bats, Thyroptera tricolor, form small, long-term social groups in which members are
loyal to a patch of forest but move on a daily basis between highly ephemeral roosting sites (partly unfurled Heliconia ...
