Animal Cognition, 2023
The ability to use environmental geometry when orienting in space reflects an animal's ability to use a global, allocentric framework. Therefore, understanding when and how animal's use geometry relative to other types of cues in the environment has interested comparative cognition researchers for decades.

Chemoecology, 2021
Neotropical poison frogs possess alkaloid-based antipredator defenses which they sequester from a diet of arthropods such as oribatid mites and myrmicine ants. Alkaloid sequestration is still poorly understood and although several studies have examined its uptake, most experiments directly feed alkaloids to the frogs.

Traumatic Injuries in Two Neotropical Frogs, Dendrobates auratus and Physalaemus pustulosus
Journal of Herpetology, 2002served juvenile V bengalensis which contained an average of almost 12 items per lizard, with predatorprey mass ratios of 0.006:0.5. He also stated that body fat accounted for over 28% of body mass in juvenile V bengalensis from Pakistan, where the animals do not feed for several months at the age of nine months.

Behaviour, 2009
AbstractAposematic prey are thought to move slowly and openly near predators, but exhibit reduced escape behaviour. We studied conspicuousness and escape by aposematic poison frogs (Dendrobates auratus and Oophaga pumilio). In circles of leaf litter, observers detected poison frogs quickly.

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2013
ABSTRACTWhole‐animal performance (e.g., swimming speed, bite force) functions as a fundamental link between organism and environment and, as such, performance characteristics are important in determining the outcomes of agonistic interactions, both interspecific and intraspecific.

QUANTITY DISCRIMINATION IN POISON DART FROG (Dendrobates auratus)
2020Many studies have argued that quantity discrimination is a shared ability across vertebrates that is inherited from a common ancestor or is a result of convergent evolution. These abilities have evolved in the form of object tracking system and approximate number system to solve similar problems across distantly related species.
