Sexual dimorphism is a fascinating phenomenon that showcases the wide variation of
characteristics related to life strategies in organisms. It is driven by two key evolutionary …

Anurans undergo significant physiological changes when exposed to environmental
stressors such as low temperatures and humidity. Energy metabolism and substrate …

In the present study, we investigated ontogenetic diet shifts, feeding strategy, prey
preferences, and basal food sources that sustain the Paradoxal frog (Pseudis minuta) based …

The niche variation hypothesis (NVH) suggests that populations released from competition
are able to expand their realized ecological niche. This increase in total niche width (TNW) …

Comparative studies of the diet of ecologically and phylogenetically close-related species
assist in understanding the evolutionary processes underlying feeding specialization. The …

Ecological studies traditionally assume that generalist populations are homogeneous in the
use of food resources, but empirical evidence supports that intraspecific differences in …

The species Boana bischoffi and Boana marginata are endemic to the Atlantic Forest, where
they often occur in sympatry. There is a large gap in the knowledge of natural history of both …

The skin of many amphibians produces a large repertoire of antimicrobial peptides that are
crucial in the first line of defense against microbial invasion. Despite the immense richness …

Information on individual trophic specialization may be relevant to better understand the
ecological adaptation of populations to their environment and the evolution of their realized …
