“…The different responses of these two frugivorous bats to land use change show the importance of considering multiple species when designing and managing biological corridors. This study demonstrates that landscape genetics approaches can serve as valuable tools for understanding how to restore and protect functional connectivity in tropical agricultural landscapes, which are underrepresented in landscape genetics (Cleary et al., ; Storfer et al., ).…”

“…In addition, Ripperger et al. () used mitochondrial DNA markers, which have a slower mutation rate than nuclear DNA microsatellite markers, and are thus less capable of detecting responses to recent landscape change (Cleary et al., ; Wang, ).…”

“…In addition, this study addresses several areas recognized as research priorities in landscape genetics. First, the majority of landscape genetics studies to date have predominantly focused on temperate species (Cleary, Waits, & Sanfiorenzo, ; Manel & Holderegger, ; Storfer, Murphy, Spear, Holderegger, & Waits, ) despite the fact that tropical regions are hot spots of biodiversity (Myers, Mittermeier, Mittermeier, da Fonseca, & Kent, ). Second, comparative landscape genetics studies of multiple species in the same landscape remain scarce, but can provide valuable insight about shared responses to landscape features (Balkenhol, Cushman, Storfer, & Waits, ; Storfer et al., ).…”

Comparative landscape genetics of two frugivorous bats in a biological corridor undergoing agricultural intensification

Agricultural intensification in tropical landscapes poses a new threat to the ability of biological corridors to maintain functional connectivity for native species. We use a landscape genetics approach to evaluate impacts of expanding pineapple plantations on two widespread and abundant frugivorous bats in a biological corridor in Costa Rica. We hypothesize that the larger, more mobile Artibeus jamaicensis will be less impacted by pineapple than the smaller Carollia castanea. In 2012 and 2013, we sampled 735 bats in 26 remnant forest patches surrounded by different proportions of forest, pasture, crops and pineapple. We used 10 microsatellite loci for A. jamaicensis and 16 microsatellite loci for C. castanea to estimate genetic diversity and gene flow. Canonical correspondence analyses indicate that land cover type surrounding patches has no impact on genetic diversity of A. jamaicensis. However, for C. castanea, both percentage forest and pineapple surrounding patches explained a significant proportion of the variation in genetic diversity. Least-cost transect analyses (LCTA) and pairwise G″st suggest that for A. jamaicensis, pineapple is more permeable to gene flow than expected, while as expected, forest is the most permeable land cover for gene flow of C. castanea. For both species, LCTA indicate that development may play a role in inhibiting gene flow. The current study answers the call for landscape genetic research focused on tropical and agricultural landscapes, highlights the value of comparative landscape genetics in biological corridor design and management and is one of the few studies of biological corridors in any ecosystem to implement a genetic approach to test corridor efficacy.
