Bat calls recorded per night (mean±SE) in forest fragments and shade coffee plantations in Chiapas, Mexico.

Land-use types are forest fragments (FF), low-management coffee (LMC), medium-management coffee (MMC), and high-management coffee (HMC). Call frequency data are from wet season 2007 only. Numbers in parentheses indicate total number of detections during 172.4 hours passive Anabat monitoring, and 20.3 hours of active Pettersson monitoring; “DS” indicates species recorded during dry season during 214.7 hours of passive Pettersson monitoring.
a. Foraging habitat: UC, uncluttered (open) space; BC, background cluttered space; HC, highly cluttered space. Because only one species (Pteronotus parnelli) is classified as an highly-cluttered space forager, we combined BC and HC foragers into the forest bat group; classification from Schnitzler and Kalko [16] and Jung et al. [40].
b. Sources for call identifications: 1, Authors’ recordings from Chiapas, Mexico; 2, Authors’ recordings from other sites in Central America; 3, Miller [41]; 4 O’Farrell et al. [17]; 5, MacSwiney et al. [15]; 6, Rydell et al. [49]; 7, Jung et al. [40]; 8, Siemers et al. [50].
c. Probably Eumops hansae (captured on one occasion) and Eumops underwoodi.
