Short-Term Population Dynamics and Microenvironment of Andinobates aff tolimensis

Ricardo Medina

Andinobates tolimensis is a threatened Andean poison frog which is virtually unknown even though it was discovered in 2007. Although a private reserve was created for its conservation, it has rarely been observed and much of its biology, ecology, behaviour, natural history, and evolution are unknown. A possible population was recently found in the corregimiento of Padua in Herveo (Tolima, Colombia). However, its morphological characteristics have not allowed us to determine if it belongs to Andinobates tolimensis or Andinobates dorisswansonae. This project seeks to determine through phenotypic and genetic evidence the identity of the Andinobates population of Padua.

Also, an estimate of short-term population dynamics, a threat assessment, and the establishment of an environment education framework. For this, calls will be recorded, a morphometric analysis will be performed, and mitochondrial genes will be sequenced. Likewise, capture-mark-recapture (CMR) techniques will be used, the presence of Batrachochytrium dendrobatidis will be evaluated, and environmental workshops with students and locals will be developed. With our results, we hope to increase the distribution range of the Andinobates in Tolima and determine population characteristics. Finally, provide systematic information to develop future management and conservation plans for the Andinobates of Tolima in conjunction with a strong strategy of awareness and appropriation by the community.
