The Siepielski Lab (https://asiepielski.wordpress.com/join-us/) invites applications for a MS student in Evolutionary Ecology. This NSF funded project will address questions focused on understanding how adaptive evolution in response to climate warming affects species tradeoffs mediating coexistence in damselflies. The MS student will join a post-doc and full-time technician dedicated to this project. Primary responsibilities will involve running field and lab experiments, conducting statistical analysis of experiments, authorship of peer-reviewed articles, and communication of findings at professional meetings. Ample opportunity exists to develop additional projects under the general themes of community ecology, population ecology, and evolutionary ecology using theory, experiments, or meta-analytical techniques. Application Details: This position is based in the Department of Biology and EEOB group at the Main Campus of the University of Arkansas (UARK). The position is funded through a mix of a teaching assistantship (9 months) and research assistantship (3 months) and includes health care benefits. There are two parts to applying for the position: 1) an application to the graduate program, and 2) an initial application to the lab. Before applying to the graduate program at UARK, potential applicants must first submit a CV/resume and a cover letter, emailed to Dr. Siepielski: amsiepie@uark.edu. The cover letter should contain a brief description of relevant experience or a desire to gain experience in evolutionary ecology. No prior experience working in the study system is required. We are looking for someone to start field work May of 2026 and begin their MS program of study August 2026. The deadline for applying to the graduate program for a fall 2026 start is January 15, 2026; however, consideration of applications will begin immediately and continue until the position is filled. For more information, please email Dr. Adam Siepielski at amsiepie@uark.edu. The University of Arkansas, Fayetteville, AR, is a RI research university located in the Ozark Mountains. The faculty and graduate students at UARK are highly interactive and include an excellent group of evolutionary biologists and ecologists. We are located in an ideal setting for field-based projects. Fayetteville, located in northwest Arkansas, offers a high quality of living at a low cost, an excellent climate, and is a large enough city to offer diverse activities and amenities. It has consistently been ranked as one of the best places to live in the US. Rock climbing, hiking, kayaking, canoeing, and especially mountain biking opportunities are in close proximity =96 NW AR is the =93Mountain Bike Capital of the World.=94 Adam M.
