Tree-fall gaps are small-scale disturbances whose formation, colonization, and role in forest dynamics are well documented, but whose effects on animal ecology are still greatly overlooked, except for studies comparing species richness of gaps 6+ months old to that in the closed canopy. Other factors associated with the invasion of fresh tree-fall gaps such as animal breeding adaptations have been largely neglected. I studied the immediate (within hours and days) arrival of the poison frog Dendrobates tinctorius in new tree-fall gaps to examine the dynamics of their invasion in relation to tadpole rearing. I found that rearing sites are occupied sooner and tadpoles deposited at higher rates in fresh gaps than in the closed forest, but that the rate of cannibalism is also much greater in the former. This suggests that invading new tree-fall gaps can be the best parental decision when parents arrive early because they get access to fresh, high-quality resources, but it could be to the detriment of the offspring if parents arrive late, because of overcrowding and cannibalism. These results highlight the importance of studying the earliest stages of invasions in order to have a better understanding of the composition of communities in disturbed ecosystems at later successional stages. ...

How far do tadpoles travel in the rainforest? : Parent-assisted dispersal in poison frogs Pašukonis, Andrius; Loretto, Matthias-Claudio; Rojas, Bibiana (Springer, 2019)Parents can influence offspring dispersal through breeding site selection, competition, or by directly moving their offspring during parental care. Many animals move their young, but the potential role of this behavior in ...
Aposematism facilitates the diversification of parental care strategies in poison frogs Carvajal-Castro, Juan D.; Vargas-Salinas, Fernando; Casas-Cardona, Santiago; Rojas, Bibiana; Santos, Juan C. (Nature Publishing Group, 2021)Many organisms have evolved adaptations to increase the odds of survival of their offspring. Parental care has evolved several times in animals including ectotherms. In amphibians, ~ 10% of species exhibit parental care. ...
Contrasting parental roles shape sex differences in poison frog space use but not navigational performance Pašukonis, Andrius; Serrano-Rojas, Shirley Jennifer; Fischer, Marie-Therese; Loretto, Matthias-Claudio; Shaykevich, Daniel A.; Rojas, Bibiana; Ringler, Max; Roland, Alexandre B.; Marcillo-Lara, Alejandro; Ringler, Eva; Rodríguez, Camilo; Coloma, Luis A.; O'Connell, Lauren A. (eLife Sciences Publications, Ltd, 2022)Sex differences in vertebrate spatial abilities are typically interpreted under the adaptive specialization hypothesis, which posits that male reproductive success is linked to larger home ranges and better navigational ...
