    • 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 ...
    • Contrasting Thermal Strategies of Montane Neotropical Bats at High Elevations 

      Garin, Inazio; Chaverri Echandi, Gloriana; Jimenez, Lide; Castillo Salazar, Cristian; Aihartza, Joxerra (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 ...
    • Diversity and Conservation of Cave-Dwelling Bats in the Brunca Region of Costa Rica 

      Deleva, Stanimira; Chaverri Echandi, Gloriana (2018-06-02)
      The Brunca region in Costa Rica contains the largest number of caves in the country, yet the diversity and distribution of bat species within those caves is currently unknown. Without this information, it is not possible ...
    • 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 ...
    • Effects of roost specialization on extinction risk in bats 

      Sagot, Maria; Chaverri Echandi, Gloriana (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, ...
    • Kinship, association, and social complexity in bats 

      Wilkinson, Gerald S.; Carter, Gerald; Bohn, Kirsten M.; Barbara, Caspers; Chaverri Echandi, Gloriana; Farine, Damien; Günther, Linus; Kerth, Gerald; Knörnschild, Mirjam; Mayer, Frieder; Nagy, Martina; Ortega Reyes, Jorge; Patriquin, Krista (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 ...
    • MURCIÉLAGOS de la región del Golfo Dulce, Puntarenas, Costa Rica 

      Haave Audet, Elène; Chaverri Echandi, Gloriana; Audet, Doris; Sánchez, Manuel; Whitworth, Andrew (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), ...
    • 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 ...
    • Repeatability in the contact calling system of Spix's disc-winged bat (Thyroptera tricolor) 

      Chaverri Echandi, Gloriana; Gillam, Erin H. (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 ...
    • Reproduction and Growth in a Neotropical Insectivorous Bat 

      Chaverri Echandi, Gloriana; Vonhof, Maarten J. (2011)
      Even though there is an abundance of data regarding the reproductive biology and postnatal growth of bats, comprehensive data on life history is still lacking for most species, particularly for rare families that have ...
    • 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 ...
    • Social communication in bats 

      Chaverri Echandi, Gloriana; Ancillotto, Leonardo; Russo, Danilo (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 ...
    • Sound amplification by means of a horn-like roosting structure in Spix's disc-winged bat 

      Chaverri Echandi, Gloriana; Gillam, Erin H. (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 ...
    • The importance of group vocal behaviour in roost finding 

      Sagot, Maria; Schöner, Caroline R.; Jago, Abigail J.; Razik, Imran; Chaverri Echandi, Gloriana (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 ...
    • Unveiling the Hidden Bat Diversity of a Neotropical Montane Forest 

      Chaverri Echandi, Gloriana; Garin, Inazio; Alberdi, Antton; Jimenez, Lide; Castillo Salazar, Cristian; Aihartza, Joxerra (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, ...
    • Variation in echolocation call frequencies in two species of free-tailed bats according to temperature and humidity 

      Chaverri Echandi, Gloriana; Quirós Ruiz, Óscar Enrique (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 ...
    • When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor 

      Buchalski, Michael R.; Chaverri Echandi, Gloriana; Vonhof, Maarten J. (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 ...
