A replicated, site comparison study in 2011–2012 of four tropical forest fragments in livestock farming areas in Córdoba, Columbia (Chacón-Pacheco & Ballesteros-Correa 2019) found that great fruit-eating bats Artibeus lituratus captured in ‘silvopastoral’ areas that used no chemicals, along with agroforestry, had higher body weights and body condition scores than those within conventional farming areas that used chemicals. Great fruit-eating bats captured in ‘silvopastoral’ areas had a higher average body weight (64 g) and body condition score (0.93) than those captured in conventional farming areas (59.5 g; 0.86). In August 2011–July 2012, great fruit-eating bats were captured at forest fragments within each of two ‘silvopastoral’ areas (total 260 bats) and two conventional farming areas (total 69 bats). ‘Silvopastoral’ areas grazed livestock amongst trees, shrubs, and crops, without chemicals. Conventional areas grazed livestock in monocultures with little tree or shrub cover, and used agrochemicals, pesticides, and herbicides. Each of four sites was sampled 15 times for three consecutive nights with mist nets (6 x 3 m) deployed within the forest fragment (nine nets) and surrounding area (five nets). Nets were deployed for 12 h/night (18:00–06:00 h) and checked every 45 minutes. Each captured bat was weighed, forearm length was measured, and body condition calculated (body weight/forearm length). Bats were marked before release.
