“…Similarly, no temporal partitioning was observed for sympatric jaguar and puma in Belize and Venezuela ( Scognamillo et al 2003 ; Harmsen et al 2011 ), with both species exhibiting similar nocturnal activity patterns. Some authors have suggested that the activity patterns of jaguars and pumas are determined by the daily activity patterns of their prey species ( Emmons 1989 ; Núñez et al 2000 , Scognamillo et al 2003 ; Harmsen et al 2011 ). As in our study, these studies found a significant overlap in activity between both predators and their main prey, lending support to the notion that predators adjust their activity to optimize energy intake and reduce energy expenditure when foraging.…”

“…The higher abundance of the sanguivorous D. rotundus toward sites with a greater amount of riparian vegetation, can occur because: 1) the riparian forest offers higher roost availability for this species [116] , [117] and/or it uses this habitat as stepping stones when searching for food in the vegetation matrix, as suggested by Estrada and Coates-Estrada [40] for explaining how this species uses forested areas when searching for food in pasture-dominated landscapes; 2) there is a higher availability of sanguivores' native food sources (mammals) in the riparian vegetation. Riparian forests contain important resources for the maintenance and connectivity of the home ranges of medium and large-sized mammals [118] , [119] , [120] . Moreover, some mammal species concentrate their activities in riparian forest, especially during the dry season when most resources are limited in the region [77] ; 3) the riparian forest also hosts a higher amount of non-native source of food (cattle), as it occurs on alluvial terraces along the channels of ephemeral and permanent streams.…”

“…Thus, robust armor appears to function primarily for defense against large carnivoran and avian predators. However, similar to species bearing spines and quills, this is an imperfect defense and they still may experience substantial predation (Núñez, Miller, & Lindzey, 2000).…”
