Conspecific and predator perception of the Red Oophaga pumilio Morph from the Central Caribbean of Costa Rica
(2020-11-04)
Strawberry Poison Frogs (Oophaga pumilio) are common members of leaf litter lowland communities in Central America and exhibit several color morphs throughout their distribution. Color plays a determinant role during intra- ...
Differences in escape behavior between a cryptic and an aposematic litter frog
(2011)
Clay models have been used to investigate the relative antipredator effectiveness of cryptic and of aposematic coloration in litter frogs, but such studies do not account for possible differences in prey escape behavior. ...
Evidence of maternal provisioning of alkaloid-based chemical defenses in the strawberry poison frog Oophaga pumilio
(2014)
Many organisms use chemical defenses to reduce predation risk. Aposematic dendrobatid frogs sequester alkaloid-based chemical defenses from a diet of arthropods, but research on these defenses has been limited to adults. ...
Discrimination of offspring by indirect recognition in an egg-feeding dendrobatid frog, Oophaga pumilio
(2009)
Offspring discrimination, the differential treatment of offspring and unrelated young, functions in numerous animal taxa to ensure that vital and costly parental care behaviours are appropriately directed. Discrimination ...
Maternally derived chemical defenses are an effective deterrent against some predators of poison frog tadpoles (Oophaga pumilio)
(2014)
Parents defend their young in many ways, including provisioning chemical defences. Recent work in a poison frog system offers the first example of an animal that provisions its young with alkaloids after hatching or birth ...
To beg or to freeze: multimodal sensory integration directs behavior in a tadpole
(2012)
Effective coordination of behaviors such as foraging and avoiding predators requires an assessment of cues provided by other organisms. Integrating cues from multiple sensory modalities may enhance the assessment. We studied ...
Conspecific and predator perception of the red Oophaga pumilio morph from the Central Caribbean of Costa Rica
(Society for the Study of Amphibians and Reptiles, 2020-09)
Strawberry Poison Frogs (Oophaga pumilio) are common members of leaf litter lowland communities in Central America and exhibit several color morphs throughout their distribution. Color plays a determinant role during intra- ...
Sexual dimorphism of the second-to-fourth digit length ratio (2D : 4D) in the Strawberry Poison Dart Frog (Oophaga pumilio) in Costa Rica
(2008)
The second-to-fourth digit ratio (2D : 4D) is a well-studied sexual dimorphism that likely arises as a result of prenatal androgenic effects on homeobox gene expression. This dimorphism has been found to exhibit interesting ...
Unraveling the contribution of climatic heterogeneity on evolutionary processes within oophaga poison dart frogs
(UniandesDoctorado en Ciencias - BiologíaFacultad de CienciasDepartamento de Biología, 2017)
Understanding the role of climatic factors on diversification processes remains among the pivotal questions in ecology and evolutionary biology. The main goal of this study was to approach this question at different temporal ...
