Abstract
Life-tables are important tools for population knowledge and conservation. This study analyzes life- tables for two isolated populations of Dendrobates auratus from Costa Rica. A direct visual survey with direct capture was completed at La Suerte Biological Station in a secondary Humid Tropical Forest on the Caribbean coast and Playa Hermosa Wildlife Refuge, a primary Very Humid Tropical Forest on the Pacific coast. A size-based classification was made based upon natural history information for the species. Static life-tables were built and statistical comparisons were made to analyze trends in life expectancy and mortality. The results showed some differences in survival, life-expectancy, and mortality rates; however, the overall population characteristics were fairly similar. Threats on their habitat and populations and isolation do not seem to have significant impacts on the life history of these populations.
