*Graduate Research Assistantship – Crayfish Distribution and Ecological Modeling*
*Location:* Texas A&M University-Kingsville *Position Start Date:* Fall 2025 *Application Deadline:* Open until filled, but applications received before April 30th will receive full consideration. *Position Description* The Mitchell Aquatic Ecology Lab at Texas A&M University-Kingsville is seeking a motivated Master’s student to join a research project focused on the distribution, habitat use, and ecological modeling of data-deficient Texas crayfish species. This student will play a key role in extensive field surveys across South Texas and assist in the development of ecological niche models to assess habitat suitability. The research will contribute directly to conservation planning for six focal crayfish species. The position is fully funded, including a stipend, tuition waiver, and research support. *Responsibilities* - Conduct extensive field surveys across South Texas to assess crayfish distributions and habitat associations. - Collect environmental and spatial data using standardized sampling methods. - Participate in ecological niche modeling using R and GIS-based tools. - Collaborate with a multidisciplinary research team, including faculty and graduate students. - Present research findings at scientific conferences and contribute to manuscript preparation for peer-reviewed journals. *Minimum Qualifications* - Bachelor’s degree in biology, ecology, fisheries, or a related field. - Strong work ethic and ability to conduct fieldwork in challenging conditions (e.g., long days in hot and humid South Texas summers). - Ability to camp for multiple days in remote areas during summer fieldwork. - Interest in ecological research and conservation biology. *Preferred Qualifications* - Experience working with crayfish or freshwater invertebrates. - Ability to operate trucks and small watercraft (e.g., kayaks, canoes). - Background in data analysis and statistical modeling (R or Python). - Proficiency in GIS software (ArcGIS or QGIS) for spatial analysis and mapping. - Strong scientific writing skills with experience in manuscript preparation or technical reports. *Funding & Benefits* - Salary of $15,000/year for two years - Full tuition/fees waiver + fringe benefits *How to Apply* Interested candidates should submit the following materials as a *single PDF* to *Dr. Zachary Mitchell* at zachary.mitch...@tamuk.edu: 1. *Cover letter* detailing research interests and relevant experience. 2. *CV or résumé*. 3. *Unofficial transcripts*. 4. *Contact information for three references*.
