Fall 2014-Fall 2016

Thesis Title:

Adaptive advantage of the ontogenetic transition of conspicuously colored tails to a cryptic morphology in the skink Plestiodon fasciatus

Midwestern State University

Tricia Neptune

Thesis Topic: Comparative eco-physiology of Anolis oculatus populations on Dominica.  

Tricia will be traveling to Dominica in the Summer of 2017 in cooperation with MWSU and Operation Wallacea to document physiological differences among the many morphotypes of the Dominican Anole across the island. She will also collect morphological data and tissues for future analyses.   

Jeanel Georges

Thesis Topic: Interspecific competition between Anolis oculatus and Anolis cristatellus: Impact of an invasive on an island endemic

Jeanel spent the Summer of 2016 educating students and gathering data in her home country of Dominica.  She is currently processing this data that will shed light on how an invasive species impacts the thermal physiology of an endemic.  Dominica was a one-Anolis island until Anolis cristatellus was introduced. This simple system will allow us to quantify the effects of this invasion on the Dominican Anole and test hypotheses regarding invasions on islands.

Fall 2014-Fall 2015

Thesis Title:

Digestive Physiology and Gut Morphology of the Ground Skink, Scincella lateralis

Charles "Matt" Watson, Ph.D.

I am an integrative evolutionary biologist with interest and training in physiology, biogeography, biodiversity, conservation, and evolutionary ecology. Current projects in my lab integrate field ecology, physiological laboratory trials, and GIS to answer broad-scale evolutionary and ecological questions.

Marcus Thibodeau, M.S.

Fall 2014-Spring 2016

Thesis Title:

The Effects of Northern Bobwhite Quail Management on the Ecology of the Texas Horned Lizard

Ciera Wolinski

Ciera is scouring the literature for metabolic rate data.  Her dataset will be used to track the evolution of resting metabolic rate among reptiles in an effort to identify patterns and determine if RMR is generally conserved, exhibits a phylogenetic signal, or if it is somewhat randomly distributed among taxa.  

 David Pérez Guerra

Tentative Thesis Topic: Effects of hypoxia on reproduction in squamates 

David comes to the laboratory from The Universidad Autónoma del Estado de México in Toluca. His interests are evolutionary ecology and physiology. David will be working to document the effects of hypoxia on the reproductive physiology of squamates.  

Jessica Duffy

Jessica is documenting morphological and behavioral differences in populations of Hemidactylus turcicus that inhabit different substrates. These invasive geckos live on a variety of man-made structures that range from brick construction to metal and glass.    

 Paige Cannedy

Thesis Topic: Effects of nicotine concentration on the physiology of the Tobacco Hornworm .  

Paige is co-advised by Watson and Mike Shipley, so she has a foot in each laboratory.  Her work will help document the effects of increased nicotine concentrations on a common tobacco pest, the Tobacco hornworm.  Nicotine is a chemical defense produced by the plant and this work will help us better understand the dynamics of this plant/animal interaction and associated evolutionary arms race.  

Science is a Team Sport.....

Hannah Richards

Thesis Topic:  Digestive Ecology and Physiology of the Texas Horned Lizard

Hannah is investigating the diet composition, available prey, and digestive efficiency of the Texas Horned Lizard in North Texas.  Working with the Dallas Zoo, she will determine how efficient these lizards are at deriving energy from their primary prey (harvester ants) and prey they frequently include in smaller amounts (beetles). She is also investigating if the composition of their diet indicates that they supplement their ant diet with beetles or that beetles simply incidentally eaten while feeding upon ants.  


Tim Torres

Tim is working in both The Watson Lab and The Shipley Lab at MWSU to characterize the lipids in milkweed leaves and ultimately document lipid transfer between milkweed and milkweed specialists.  He is part of a small group of undergrads working on plant/animal interactions with Monarch Butterflies and Milkweed.
