Caz Taylor, PhD

Caz Taylor PhD (Associate Professor). I am a population ecologist. I use mathematical or computational methods combined with field experiments to investigate the dynamics of species. I am particularly interested in how movements of species that are spatially distributed affect their population dynamics. I work on theoretical investigations using network models to describe migratory species as well as larval dispersal in marine species.

Rosalyn Rael, PhDRosalyn Rael (Postdoctoral Researcher). I am a mathematical biologist interested in the evolution of ecosystem structure and the impacts of the confluence of humans and natural ecosystems on patterns of species abundance and diversity. My previous researched has focused on the dynamics and evolution of competition and predator-prey relationships using networks, differential and difference equations, stochastic models, and evolutionary game theory. Currently, my work involves modeling the dynamics of a pathogen reservoir host species to assess changes in the distribution of human exposure risk through time, as well as the societal and ecological impacts of intervention and control strategies. 


John A. Herbert (PhD Student). I am investigating the non-breeding ecology of shorebirds in North America and South America, with an emphasis on semipalmated sandpipers. My research will focus on stopover habitat in the northern Gulf of Mexico and wintering habitats in French Guiana, Suriname, and Brazil. With the use of GIS, remote sensing, nanotags and Motus towers, I aim to further the understanding of the migratory connectivity and non-breeding survival of shorebirds.


Christen Steele (PhD Student). I study trends in the population and community ecology of insects in human dominated landscapes (urban and agricultural systems). I am most interested in how interactions between insects, anthropogenic habitat change and diseases and/or parasites influence population dynamics of species. My goal is to use our understanding of these interactions to promote the conservation of beneficial insects and their associated ecosystem services. For my masters research I studied how interactions between pasture management, dung beetle activity, and red imported fire ant (Solenopsis invicta) activity influence both the rate of dung degradation and the survival of livestock parasites incubating within dung. For my PhD, I plan to focus on the impact of habitat variables on monarch and parasite/parasitoid dynamics in the Gulf Coast region, where a small percentage of monarchs have been found to be dropping- out of the migratory cycle in order to breed year-round. As asides to my project, I am also interested in open science and its ability to improve the applicability of research, citizen science as a tool to increase science literacy, and promoting female participation in research.

Fabiola Rodriguez (PhD Student). My research interests include ecology and conservation of avian systems. My research experience stems from participating in several projects that have focused on Neotropical birds in various ecosystems in Central America (mainly Honduras and Nicaragua). I completed my Master’s research at Indiana University of Pennsylvania, where I studied the distribution and habitat-abundance relationships of the Honduran Emerald hummingbird, an endemic bird species that inhabits the threatened dry forests. Through these previous experiences, I have learned how research can serve as a foundation to inform conservation actions. During my PhD I want to accomplish three objectives: i) contribute to wintering ecology theory of migratory birds that use different Central American ecosystems; ii) design and conduct research that integrates field experiments and the advances in modeling techniques to study wintering ecology; and iii) conduct research that may be useful to conservation partners across the region to mitigate threats that currently affect migratory bird populations.

Kiah Williams (PhD Student). I am interested in studying the effects of dune renourishment on shorebird survivorship and fecundity in coastal Louisiana. In gaining more insight into how coastal restoration affects shorebird ecology, I hope to improve land management and wildlife monitoring techniques for coastal restoration agencies.
