Ryan Calsbeek

Dartmouth College

Ryan is an evolutionary ecologist whose research focuses on population genetics, natural and sexual selection, and behavioral ecology. Ryan and I have several long-term projects underway in The Bahamas, foremost among them being our studies of sexual conflict and the costs of reproduction in the brown anole. We also study the evolution of performance, the roles of predators and competitors in shaping natural selection, and the evolution and maintenance of polymorphism.

 

Henry John-Alder

Rutgers, The State University of New Jersey


Henry is a physiological ecologist whose research integrates aspects of endocrine physiology, morphology, and behavior. Henry was my dissertation advisor at Rutgers, where we collaborated on studies of the evolution and endocrine regulation of sexual size dimorphism.  As you can see, Henry also enjoys studying social dynamics in terriers.

Joe Williams

The Ohio State University

Visit the Williams Lab


Joe is a physiological ecologist whose research focuses on physiological adaptations to extreme environments. Along with Agus Munoz-Garcia, Joe and I collaborated on a series of studies in which we investigated how birds alter their metabolism and cutaneous water loss in response to arid conditions.

Tim Connallon

Cornell University


Tim is an evolutionary geneticist who studies sexual antagonism and sex linkage in fruit flies. Along with Ryan Calsbeek, Tim and I recently developed a population-genetic model to examine whether sex differences in selection typically reduce or add to the inherent two-fold cost of sex.

Emily Taylor

California Polytechnic State University


While I was studying sexual size dimorphism in lizards, Emily was conducting a very similar dissertation project on rattlesnakes at Arizona State University. Along with Henry John-Alder, Emily and I have collaborated on studies of the endocrine regulation of sexual size dimorphism in reptiles. Emily’s group at Cal Polytech is now planning to characterize the effects of testosterone on growth in additional lizard species.

Marguerite Butler

University of Hawaii

Visit Marguerite’s website


Marguerite is an evolutionary biologist whose interests range from functional morphology to comparative biology. Along with Henry John-Alder, Marguerite and I collaborated to write a book chapter summarizing the literature on sexual size dimorphism in reptiles.

Rocco Carsia

University of Medicine and Dentistry of New Jersey


Rocco is an endocriniologist who studies adrenal steroidogenesis in birds and reptiles. In collaboration with Henry John-Alder, Rocco and I have begun to characterize the regulation of adrenal steroidogenesis in lizards. Our studies add a comparative, ecological twist to this classic area of endocrine research.
