Donald McGahan

Dr. McGahan's research examines the slowly renewable natural resource, soil, on which the majority of life planet depend. He uses multiple low and high technology tools to investigate hows and whys to further understanding this diverse ecosystem. Currently under investigation are phosphorus forms and contents on agricultural lands and the impacts and fates thereof as a result of both natural erosion and accelerated erosion. mcgahan@tarleton.edu

Darrel Murray

Dr. Murray's current research projects include conversion of species-poor mesquite savannas to more native diverse grasslands, using citizen science to map Monarch butterfly and native Texas milkweed occurrence, and using ecological niche data to map rare plant species along Texas roadways. Dr. Murray also has an interest in using prescribed fire for restoration and has a core group of students that participate in prescribed burning. dmurray@tarleton.edu

James P. Muir

Dr. Muir has on-going research in Pernambuco Brazil and throughout Texas. His long-term focus has been legumes, bothcultivated and natural, and their myriad roles in pastures, rangeland, prairies,and savannahs. His multi-national team looks at the many facets of legumecondensed tannins as they affect plant survival, herbivory, and carbonsequestration, as well as animal and environment health. His students currentlyfocus on domesticating native Texas legume ecotypes for many uses, includingprairie restoration and roadside revegetation. j-muir@tamu.edu

STUDENT RESEARCH

Alisa McAnally

Under the direction of Dr. T Wayne Schwertner and Dr. Heather Mathewson, I am studying the American bison located at Caprock Canyon State Park. Our study will track the movements of bison via GPS telemetry to scrutinize habitat selection and avoidance. The goals of the project are to help the park with further management of the herd and conduct theoretical analysis regarding habitat selection on a small scale.

Amy Okichich

Cottonseed products have been used as a feed supplement for ruminant livestock and white-tail deer (Odocoileus virginianus) for many years. Although cottonseed products are nutritious, they also present possible risks due to the presence of gossypol. Gossypol, a secondary plant compound found in cotton (Gossypium ssp.), is known to be toxic to a variety of animals, particularly monogastric mammals and birds. However, there are no published data regarding the effects of gossypol on northern bobwhites (Colinus virginianus), which may encounter cottonseed products in the environment and subsequently ingest gossypol. The primary purpose of my study is to evaluate the acute toxicity and physiological effects of gossypol ingestion on northern bobwhites.

Conor McInnerney 

Under the direction of Dr. Heather Mathewson. White-winged dove (Zenaidia asiatica, WWDO) populations have expanded over the last few decades and are now associated with urban environments more than rural ones (81.2% and 19.8%, respectively; TPWD). Given their increasing importance as a game species, TPWD expanded monitoring efforts in 2008 to provide a statewide Urban Dove Survey (UDS). Objectives of my study are to 1) Increase the efficiency of the UDS by identifying areas that are over/under sampled, 2) update the urban classification for Texas as the original survey was designed using the National Landcover Database from 1992, and 3) estimate the density of urban WWDO, mourning dove (Z. macroura), and Eurasian-collared dove (Streptopelia decaocto) across Texas. To accomplish this, we will conduct a Multi-Response Permutation Procedure (MRPP) analysis using band recovery data to delineate populations of WWDO within Texas. Using Program DISTANCE 7.0 for density estimates, we will address the survey effort issue based on the MRPP analysis. And using ERDAS Imagine or similar software, we will update the urban classification for the state.

Jared Hall

Under the leadership of Dr. Heather Mathewson, Jared is using banding and hunter recovery data collected by Texas Parks and Wildlife from 2003-2015 to investigate the factors that impact annual survival and understand breeding chronology of white-winged doves in Texas.

Joseph Wilson

I am using 13 years of Texas mourning dove banding data provided by Texas Parks and Wildlife. By analyzing banding data beginning in 2003, variables effecting annual survival of mourning dove will be identified. Top models will be produced with the combination of covariates most effecting survival and be used in an adaptive harvest management plan. The management implications of using this method to estimate population status are monumental and will use much less resources annually, saving the state and its citizen’s money.

Julia (Roze) Shipman

I graduated from Tarleton in December with a Bachelor’s of Science in Wildlife, Sustainability and Ecosystem Science. Now I am pursuing a Master’s degree in the same field. The research project I am working on with Dr. Jim Muir, is the conversion of monoculture Bermuda pastures to ranges with native grasses and legumes for livestock grazing as well wildlife habitat.
Another graduate student began this first phase of this project two years ago, his research was suppression of the Bermuda grass. Now I will be partnering with another graduate student to prepare the soil, select appropriate native species and compare different seeding methods as well as mowing vs. mob grazing.

Melissa Hopkins

Under the direction of Dr. Jeff Breeden and Dr. T. Wayne Schwertner, I am investigating the effects of Reticuloendotheliosis Virus (REV) using northern bobwhite quail as a model. Specifically, my project will establish whether or not northern bobwhites are susceptible to REV infection (as it has never been documented in this species), and if the virus effects the bobwhites' reproduction, as REV has been known to cause reproductive suppression in similar species.

TxDoT Rare and Endangered Plants Project: A joint effort between the Botanical Research Institute of Texas  and Tarleton to compile data on 56 rare and endangered plants from herbarium and citizen science records. The data will then be mapped in GIS to determine which locations within the TxDoT Districts of Waco and Austin will be most likely to contain these plants based upon geology, soil, rainfall, temperature, etc. The maps will then be utilized by TxDot for road planning and roadside management.

TPWD Conservation License Plate Milkweeds and Monarchs Project: Data will be compiled on native milkweed plants in the 115 Texas counties within the monarch butterfly central fly zone. This data will be mapped in GIS and a record of monarch migration patterns will be overlaid in order to determine which counties are in most need of milkweed restoration.
