Stanley Fox (Emeritus Regents Professor)
Stanley graduated with a Ph.D. from Yale University in 1973, spent two years as a postdoctoral researcher at the Millbrook Field Center of Ecology and Ethology, Rockefeller University, then two years as a temporary Assistant Professor at Boston
University, before joining the Department of Zoology (now Integrative Biology) at Oklahoma State University as an Assistant Professor in 1977. He retired from teaching in the summer of 2013 at the rank of Regents Professor, but remains very active in research and publication. He is interested in a wide range of questions including social behavior of lizards, tail autotomy, sexual selection, and parental care in lizards, as well as diversity and conservation of reptiles and amphibians in and around Oklahoma and in South America, role of disease (Bd fungus and ranavirus) in amphibian declines, and temperature-dependent sex determination in collared lizards. His 
current research predominantly focuses on precocial sexual selection in collared lizards, parental care and group living in Liolaemus leopardinus, and effects of climate change on altitudinal range shifts in Chilean Liolaemus in the altiplano of central Chile.

Recent Past Graduate Students
Jaina Agan (Ph.D.)
Jaina started at OSU after completing her undergraduate degree at Clayton State University in Atlanta, Georgia. She is focused on the field of herpetology and is interested in several topics within the field. These topics include, but are not limited to, behavioral ecology, ecology, evolution, sexual selection, and biodiversity. Jaina joined the Precocial Sexual Selection in Collared Lizards project and her research used field experiments to gauge how male hatchling orange bars play a role in interactions of males with hatchling females and other hatchling males, how the orange bars may help determine the genetic fitness of the bearers, the proximate cause of the bars, and the possible predation costs of the hatchling orange bars. Jaina completed her doctoral degree in the summer of 2021 and is now a tenure-track Assistant Professor in the Department of Biology at the University of Central Oklahoma.

Jodie Wiggins (Ph.D.)
Jodie's dissertation research focused on a long-term study of the costs and benefits of a conspicuous sexual dichromatism in hatchling collared lizards: bright orange lateral bars in males. She showed Precocial Sexual Selection in these lizards, juvenile-specific male traits that increase fitness once those individuals lose those traits and sexually mature. Jodie graduated in July 2018 with her PhD and before that received her M.S. degree in 2010 from Midwestern State University in Wichita Falls, Texas. She was co-advised by departmental collaborator Matt Lovern. She is currently a Teaching Assistant Professor at OSU. Jodie is interested in various aspects of behavioral ecology, but especially genetic components.

Enrique Santoyo-Brito (Ph.D.)
Enrique received his Licenciatura degree in Biology from the Universidad Veracruzana, and a Master's degree in Conservation and Wildlife Management from the Colegio de Postgraduados, Texcoco. Both Academic Institutions are located in Mexico. He is interested in a wide range of topics within herpetology. Topics include parental care, social behavior, sexual selection, evolutionary ecology, climate change and its different effects over reptile communities and populations, egg incubation temperatures and sex ratio in collared lizards, predator escape behavior of Chilean lizards, and herpetological conservation and biodiversity. He has conducted herpetological research in Mexico, United States of America, and Chile. His doctoral dissertation focused on group living and parental care of neonates in Liolaemus leopardinus a high-elevation, social, lizard species of the Andes in Central Chile, South America. Enrique graduated with his PhD in December 2017, held a postdoctoral position in the OSU Collection of Vertebrates after that, and then stayed on at OSU for another year as a Visiting Assistant Professor. He is now a Scientific Specialist in the Biological Collections of the Prairie Research Insitute at the University of Illinois.

Andrea Acevedo (Ph.D.)
Andrea graduated with her PhD from OSU in July 2015. She is interested in all aspects of animal behavior, evolution, sexual selection, ecological immunology and animal coloration. Her doctoral research focused on sexual selection in hatchlings of the collared lizard, studying how the intensity of orange coloration in male hatchlings relates to testosterone levels, aggression, and ultimately individual fitness.

Matt Anderson (Ph.D.)
Matt finished his PhD from OSU in the spring of 2013. He was Zoology’s Outstanding PhD student in 2012 and won the all-university Marshall Award in 2013, among many other awards. Matt examined the costs associated with tail autotomy, a valuable antipredatory tactic, in the lizard Uta stansburiana. He showed that tail autotomy leads to changes in sprint performance, mating strategy, territorial aggression, and territory size and quality. After tail loss, males adopted an alternate reproductive tactic—they became sneaker males. Matt is now a Teaching Assistant Professor at Florida International University.

Dan Moore (M.S.)
Dan finished his M.S. degree at OSU in May 2011.

Kendall is an OSU undergraduate who fell in love with animals at an early age. She started college as a zoology major, but has recently changed to sociology. Kendall mainly focused on the project with predation by native coachwhip snakes on collared lizard juveniles. She was part of a team that is running trials on predation preferences of coachwhips when given the option between a bright male juvenile with orange bars and a drab male juvenile with no orange bars (the trials do not permit the actual predation to take place, just the snake's choice). This project is measuring the cost of a dichromatic signal that the lab is investigating for its role in precocial sexual selection in collared lizards.

Research
In general, my lab and I advance and utilize a field experimental approach to behavioral and evolutionary ecology, employing mostly lizards as model subjects. We are particularly interested in the development of lizard social organization at both the ontogenetic and evolutionary levels, studying lizards in the United States, Mexico, and Chile. The study of sexual selection is an important aspect of that. Another focus is the behavioral ecology associated with tail autotomy in lizards, exploring the use of the tail in lizards as a status signalling badge. We also conduct research on herp community ecology, especially freshwater turtle communities. A recent, applied, research focus is on the distribution, abundance and habitat affiliations of the Ringed Salamander in Oklahoma--an ecologically cryptic, episodic, fall breeder from the mountainous eastern part of the state. Some of my students and I have been involved in research related to worldwide amphibian declines, especially those related to ranavirus and the chytrid fungus Bd.

Welcome to the Fox Lab at OSU
Our lab focuses on behavioral aspects of evolutionary ecology of natural populations, especially of reptiles and amphibians. Specifically, we are interested in understanding how sexual selection molds contemporary populations and how parental care and social behavior have evolved, especially in lizards. Additionally, we have conducted investigations related to tail autotomy in lizards, freshwater turtle conservation in Oklahoma, temperature-dependent sex determination in collared lizards, and the role of the Bd fungus (chytrid fungus) and ranavirus in amphibian declines in Latin America, especially in Patago
nia. Our approach to these problems is necessarily integrative and collaborative. We combine concepts and methods from various biological disciplines ranging from ecology, evolution, and animal behavior to physiology, endocrinology, immunology and genetics. Our research is heavily field-based, supplemented with analytical and experimental approaches in the laboratory, and is/has been conducted in Oklahoma and neighboring states, Canada, Argentina, Chile, Mexico, and Madagascar.
