​
Reuber is interested in community ecology and biotic interactions, especially  understanding how biodiversity changes over space and time. He field work has mostly been conducted in rain and dry forests, savannah, and mountains in tropical and subtropical systems.

B.S., Wildlife and Fisheries Sciences 
Texas A&M University
Connor is currently studying the movements and habitat selection of  Alligator Snapping Turtles (Macrochelys temmickii).

Connor's M.S. project examined the effects of forest management practices on food-web structure and trait-based community organization in upland pine ecosystems.

David Rosenbaum
M.S. Student, Forestry

B.S., Environmental Science
Baylor University
David is surveying Alligator Snapping Turtles (Macrochelys temmickii) in Texas to elucidate their current distribution, occupancy, and mercury loading in relation to various microhabitat, watershed, and landscape variables. Because the species is at high risk of extirpation in the state, these results will inform conservation strategies.

Tatiana Suarez Joaqui
PhD. Student, Forestry

M.S., Ecology
Instituto de Ecología A.C.

B.S., Biology
Universidad del Quindío

Tatiana is interested in species diversity and community ecology. She has developed an interest in dung beetles and anurans to address questions in these fields. Her dissertation research will be focused on amphibian ecology.

M.S. Student, Environmental Science

 
B.S., Natural Resource Ecology and Management
Oklahoma State University
Jake is studying role of environmental variables on fish community assembly across multiple spatial scales.  Specifically, he will examine how fish functional traits correlate to  environmental variables in Texas streams.

Jake is co-advised by Dr. Carmen Montaña.

Ashley is studying mechanisms of establishment of the non-native Brown Widow Spider (Latrodectus geometricus) in a native spider community.

Liam Wolff
M.S. Student, Forestry

​B.S., Ecology
Augusta University

Liam is studying the distribution of the Bachman’s Sparrow (Peucaea aestivalis) on the western fringe of its range across a habitat quality gradient. Liam is also studying the correlates of their singing phenology. This research aims to evaluate covariates of their occupancy as well as inform future monitoring programs.

Undergraduate Students

Veda Allen 
​Forestry
Veda is studying the geographic and latitudinal variation in calling phenology for five species of anurans that occur across three different sites in east Texas.

Kasey Jobe
Biology
Kasey is currently working the song diversity of Bachman's sparrow. 

For the past two summers, Kasey studied the risk of snake entanglement in erosion control products. Kasey also studied the predators of salamanders by quantifying their diversity  and their predator-prey size relationships.

Lab Alumni

John Michael Arnett (2020)
B.S., Forestry - Forest Wildlife Management
John Michael studied the overlap of non-native Mediterranean House Geckos (Hemidactylus turcicus) and lizards native to East Texas (Plestiodon, Scincella, Anolis spp.) along multiple niche dimensions, including their habitat, trophic, and isotopic niches.

Sarah Ebert (2019)
B.S., Biology - Ecology and Evolutionary Biology
​Minor - Forestry
Sarah worked on a project examining snake entanglement in erosion control mesh netting. Results from this project have implications for practices that minimize threats of erosion control materials on wildlife.

Hailey Hester (2019)
B.S., Forestry - Forest Wildlife Management
Hailey described the advertisement calls of the frogs from the Gran Chaco ecoregion of Bolivia.

Nick Schiwitz (2019)
B.S., Forestry - Forest Wildlife Management
​Minor - Spatial Science
​Nick studied the activity rate - predation risk tradeoff in larval anurans. This work sought to understand  how interspecific variation in activity rate corresponds to species' distributions  along the pond  hydroperiod gradient.

Nick also studied the risk of snake entanglement in erosion control products.

Dylan Thompson (2020)
B.S., Forestry - Forest Wildlife Management
Dylan investigated the functional role of the Little Brown Skink (Scincella lateralis) in East Texas forest food webs. He quantified the abundance,  biomass, and occupancy of skinks across a forest management gradient.

Krista Ward (2019)
B.S., Biology - Ecology and Evolutionary Biology
​Minor - Forestry
Krista studied the effects of installation method of erosion control blankets on snake entanglement. She also classified the diversity of available erosion control products based on their different attributes.
