ARIAS-AGUILAR, Adriana; CHACON-MADRIGAL, Eduardo  and  RODRIGUEZ-HERRERA, Bernal. El uso de los parques urbanos con vegetación por murciélagos insectívoros en San José, Costa Rica. Mastozool. neotrop. [online]. 2015, vol.22, n.2, pp.229-237. ISSN 0327-9383.

We evaluated habitat use of insectivorous bats in five urban parks in San José, Costa Rica. Three sessions of acoustic monitoring were carried out for three nights, between 18:00-19:30 h. A total of 457 recordings (402/large parks, 44/small parks, 11/controls) were obtained. Large parks were sites of greater richness and activity than those lacking vegetation (controls). There was no significant difference in the number of species between small and large parks; however, the park use differed significantly between species. Parks cannot replace natural conditions but are important for maintaining the remaining diversity of bats in urban sites.
