A call-and-response system facilitates group cohesion among disc-winged bats
Chaverri Echandi, Gloriana; Gillam, Erin H.; Kunz, Thomas H. (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 ... -
All-offspring natal philopatry in a Neotropical bat
Chaverri Echandi, Gloriana; Kunz, Thomas H. (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 ... -
Ecological Correlates of Range Size in the Tent-Making Bat Artibeus watsoni
Chaverri Echandi, Gloriana; Quirós Ruiz, Óscar Enrique; Kunz, Thomas H. (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 ... -
Ecological Correlates of Roost Fidelity in the Tent-Making Bat Artibeus watsoni
Chaverri Echandi, Gloriana; Quirós Ruiz, Óscar Enrique; Gamba Rios, Melquisedec; Kunz, Thomas H. (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 ... -
Mating System of the Tent-Making Bat Artibeus watsoni (Chiroptera: Phyllostomida
Chaverri Echandi, Gloriana; Schneider, Christopher J.; Kunz, Thomas H. (2008-12)Vertebrate mating systems are influenced by ecological and phylogenetic factors, and the variation observed in mating behavior is frequently attributable to the extent to which male assistance in the rearing of offspring ... -
Range overlap and association patterns in the tent-making bat Artibeus watsoni
Chaverri Echandi, Gloriana; Gamba Rios, Melquisedec; Kunz, Thomas H. (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 ... -
Reproductive biology and postnatal development in the tent-making bat Artibeus watsoni (Chiroptera: Phyllostomidae)
Chaverri Echandi, Gloriana; Kunz, Thomas H. (2006)In this study we investigated the reproductive patterns and postnatal development in the tent‐making bat Artibeus watsoni. We sampled two populations in the Golfito Wildlife Refuge and Corcovado National Park, south‐western ... -
Response of a Specialist Bat to the Loss of a Critical Resource
Chaverri Echandi, Gloriana; Kunz, Thomas H. (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 ... -
Roosting Ecology of the Tent-Roosting Bat Artibeus watsoni (Chiroptera: Phyllostomidae) in Southwestern Costa Rica
Chaverri Echandi, Gloriana; Kunz, Thomas H. (2005-11)We described the plants used as roost resources by Artibeus watsoni in southwestern Costa Rica, assessed roost fidelity, and compared roosting ecology between two sites, Golfito and Corcovado, which vary in the degree of ...
