      This study explores interspecific acoustic mimicry in mammals, particularly focusing on the greater mouse-eared bat (Myotis myotis) distress calls. These calls imitate stinging bee and wasp sounds, aiming to deter avian ...
    • Comparing the efficiency of monofilament and traditional nets for capturing bats 

      Chaves Ramírez, Silvia; Castillo Salazar, Cristian; Sánchez Chavarría, Mariela; Solís Hernández, Hellen; Chaverri Echandi, Gloriana (2021)
      Traditional mist nets used for capturing bats have several drawbacks, particularly that they are inefficient at sampling many insectivorous species. One possible alternative is to use monofilament nets, whose netting is ...
    • Contact calling in context: intra- and intergroup variation in vocalization rates depend on a call’s function 

      Chaverri Echandi, Gloriana; Araya Ajoy, Yi-Men Gerardo; Sagot, Maria (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 

      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, ...
    • Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet 

      Chaverri Echandi, Priscila; Chaverri Echandi, Gloriana (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 

      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 ...
    • Landing manoeuvres predict roost-site preferences in bats 

      Chaverri Echandi, Gloriana; Araya Salas, Marcelo; Barrantes, Jose Pablo; Uribe Etxebarria, Tere; Peña Acuña, Marcela; Varela, Angie Liz; Aihartza, Joxerra (2022-11-11)
      Roosts are vital for the survival of many species, and how individuals choose one site over another is affected by various factors. In bats, for example, species may use stiff roosts such as caves or compliant ones such ...
    • 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)
