<abstract>

The La Suerte Biological Field Station in Costa Rica was visited during May/June 2007 in order to analyze the Strawberry Poison Dart frog, D. pumilio, and to understand what microhabitats they use and where they might be more reproductively active. Line transects of 5 meters in length were done in order to assess the D. pumilio habitats and activity. Perpendicular distance in 0.25 meter increments from each transect were recorded for each D. pumilio sighting. These sightings were classified as either adults or froglets, using the size criteria of 10mm or smaller as froglet with anything larger being considered an adult. At each location any reproductive activity such as male calling and/or tadpole transportation was noted, as well as the hours since the last rainfall. After this initial ‘snapshot’ of each transect , 10 minutes were spent analyzing the habitat for amount of ground cover from leaf litter, average leaf size in the litter, and thickness of the litter layer.

<purpose>

One method of assessing the quality of an environment is by monitoring amphibians (Braun 2005). Many species of amphibians require vegetation for attachment of egg masses, not only living vegetation but dead vegetation such as leaf litter as well (Savage, 2002). Since larval forms of amphibians are aquatic, their presence also shows water quality and condition of the watershed. Finally, invertebrates are a major food source for both adults and larvae, so the substrate type and must be adequate for their life cycle. For these reasons, amphibians are perceived as an excellent indicator of the climate, habitat stability and litter decomposition of an environment. Monitoring D. pumilio reproduction in a spatially explicit way will provide clues as to what type of microhabitat this species prefers, and how well they can adapt to a secondary growth rainforest. This may give insight as to the process of reinhabiting and repairing forest gaps as well as understanding the qualities needed for an initial amphibian population to develop in a specific environment.

Line transects of 5 meters in length were done in order to assess the D. pumilio habitats and activity. Perpendicular distance in 0.25 meter increments from each transect were recorded for each D. pumilio sighting. These data were analyzed with Distance Sampling. Sightings were classified as either adults or froglets, using the size criteria of 10mm or smaller as froglet with anything larger being considered an adult. At each location any reproductive activity such as male calling and/or tadpole transportation was noted, as well as the hours since the last rainfall.
