Experimental evolution of sex ratio and sex-determining mechanisms in C. elegans

To complement our work on the evolution and ecology of sex-determining mechanisms, especially temperature-dependent sex determination (TSD), in reptiles, we are developing strains of the nematode "worm" Caenorhabditis elegans as

Anthropogenic influences on turtle populations

Many reptiles, including many turtle species, are increasingly impacted by human activity.

Evolutionary ecology of sex-determining mechanisms in reptiles

A fundamental problem in biology is understanding the ecology, genetics, and evolution of diverse sex-determining mechanisms.

Life-history evolution and functional ecology of reptiles

Egg and offspring size, as well as other morphological and behavioral performance traits, play important roles in life-history models yet they vary greatly both within and among populations and taxa and temporally (Tucker et al., 1998, J.

Phylogenetics, molecular ecology, and phylogeography of North American reptiles

The structure of natural populations and the intraspecific relationships among these populations provides a crucial context for understanding the historical, current, and future evolution of organismal phenotypes.
