62!

A tentative herp count from my four months in Costa Rica: 62 species.  It may increase (or decrease) slightly as I add and update photographs with uncertain identification and scientific names from Savage and Bolanos (Zootaxa 2009).  The majority of the herps discovered were reptiles, which makes sense, given my extended stay in the dry forest.  I missed out on much of the phenomenal diversity of anurans and didn’t see a single salamander because they tend to be more diverse in wetter parts of the country.  When I was in those areas (i.e., the Osa Penninsula), it was the dry season, so many of the herps were hiding out.

Litter release - Rio San Lorencito Upstream 4-5-2009 6-45-31 AM

No artificial leaves ever made it to the end of our 30-m release, where the seine was set for their capture.  This is an interesting find, since litter biomass is relatively low in the stream itself; where is it going? Are tadpoles, which do appear to be abundant, processing litter?
