“…However, we found no evidence that diet changes in the same direction as insect abundance/diversity. We observed a more diverse diet in the dry season when arthropod abundance is actually lower in the area (Andresen 2005;G€ uizado-Rodríguez & Casas-Andreu 2011;Razo-Gonz alez et al 2014). In particular, P. davyi and P. personatus increased their dietary breadth in the dry season.…”

“…Tropical dry forests frequently show extreme changes in the available resources during the wet and dry season, therefore altering the composition and diversity of fauna (Razo‐González et al . ). Furthermore, the abundance of arthropods in particular shows considerable fluctuations in tropical dry forests, reaching its lowest levels in the dry season and its highest levels in the wet season (Levings & Windsor ), a pattern reported for Chamela (Pescador‐Rubio et al .…”

“…We also predict that diet in all three species exhibits seasonal changes over the year reflecting changes in arthropod diversity (Andresen ; Güizado‐Rodríguez & Casas‐Andreu ; Razo‐González et al . ).…”

Competing hypotheses explaining species' use of resources have been advanced. Resource limitations in habitat and/or food are factors that affect assemblages of species. These limitations could drive the evolution of morphological and/or behavioural specialization, permitting the coexistence of closely related species through resource partitioning and niche differentiation. Alternatively, when resources are unlimited, fluctuations in resources availability will cause concomitant shifts in resource use regardless of species identity. Here, we used next-generation sequencing to test these hypotheses and characterize the diversity, overlap and seasonal variation in the diet of three species of insectivorous bats of the genus Pteronotus. We identified 465 prey (MOTUs) in the guano of 192 individuals. Lepidoptera and Diptera represented the most consumed insect orders. Diet of bats exhibited a moderate level of overlap, with the highest value between Pteronotus parnellii and Pteronotus personatus in the wet season. We found higher dietary overlap between species during the same seasons than within any single species across seasons. This suggests that diets of the three species are driven more by prey availability than by any particular predator-specific characteristic. P. davyi and P. personatus increased their dietary breadth during the dry season, whereas P. parnellii diet was broader and had the highest effective number of prey species in all seasons. This supports the existence of dietary flexibility in generalist bats and dietary niche overlapping among groups of closely related species in highly seasonal ecosystems. Moreover, the abundance and availability of insect prey may drive the diet of insectivores.

“…The significance of arthropods for ecosystem functions and soil has been determined regarding their biodiversity and abundance. Body sizes, forms and some organs of the soil arthropods allow them to live in various layers and depths of the soil (Razo-González et al 2014). Arthropods can live on the forest floor, in the pores of litter and soil.…”
