I am a graduate student at the University of California, Riverside and was fortunate to spend a large portion of the 2009-2010 wet season in Trinidad working on the FIBR project. Specifically I was part of the team doing the monthly guppy mark-recapture in the four focal sites. When not catching and processing guppies I worked on two projects on Rivulus hartii, a widespread killifish that co-occurs with guppies. I did a mark-recapture study on Rivulus hartii in order to assess size specific mortality in different predator/competitor communities. I also collected Rivulus from sites across the north slope of the northern range mountains. These Rivulus are now being dissected and life history data (size at maturity, number of eggs, and reproductive allocation) is being quantified. The goal is to determine if the life histories have evolved in ways predicted by theory, and in a way analogous to what has been found in Rivulus from south slope streams.
