Blogging about the conservation of Darwin's Frogs
  • The first frogs in our facility: Sweet Success
    Once all of the environmental systems in our captive breeding facility checked out, we added our first group of frogs.  Somewhat surprisingly, the frogs immediately began enacting reproductive behavior.  We had calling and a bit of dancing around between males and females.  We are happy to report that we already have at least one male [...]
  • Placing the finishing touches on the breeding center
    The captive breeding facility at the National Zoo in Santiago has been developing very well.  Thankfully, no damage was done during the earthquake.  Our hearts go out to all of those that lost property and loved ones in the terrible natural disaster.  We are all very pleased with how the climate control worked through the [...]
  • Field Work
    Our travels around Chile have been many.  We are always investigating new and historic localities for Darwin’s Frogs.  We wanted to provide an idea of some of the sights we have been taking in during our field adventures.

 Functional and Evolutionary Morphology; Comparative Physiology
University of Massachusetts
AMHERST, MA

Functional morphology of intromittent organs in two groups of vertebrates: amniotes and teleost fish. Intromittent organs have evolved several times in both groups -- as inflatable penises in amniotes, and as modified anal fins called gonopodia in teleosts. I use anatomical and biomechanical techniques to examine how intromittent organs perform under the mechanical regime imposed by copulation.

In a nutshell, it's about unraveling the mobius strip of how organisms perform their behaviors, how sources of variation affect that performance, and how that performance affects evolution. Raising related species under a set of different environments can reveal whether the deveolpmental response to the environment has evolved. Together with an understanding of the animals' natural environments and the results of a variety of performance tests, functional variation can be used to interpret evolution.
