Drs. Michael Fraker (https://ael.osu.edu/people/fraker.24) and Stuart Ludsin (www.ludsinlab.com/) have an opening for a MS (or possibly Ph.D.) student to begin during fall 2017 (with funding to begin as soon as March). The student would work on a project designed to better understand how prey integrate phenotypically-plastic antipredator defenses (behavior, morphology) over their development. The student also would work closely with collaborators on the project (Dr. Robert Denver, University of Michigan; Dr. Barney Luttbeg, Oklahoma State University) and would have opportunities to initiate independent research related to project objectives. 

Project description: Amphibian tadpoles display extensive phenotypic plasticity in anti-predator defenses that enhance fitness by increasing survival to metamorphosis. While the induction of these defenses and their evolutionary and ecological significance have been extensively studied, the proximate mechanisms that underlie them are largely unknown. Because these responses are employed with different lags to predator exposure and have different consequences to species interactions, we must learn how these responses are mechanistically integrated and what tradeoffs are implicated.

We found that tadpole anti-predator defenses are partly controlled by a bimodal physiological stress response that is initiated by an alarm pheromone released from tadpole skin in response to predator attack. Tadpoles suppress behavior and their neuroendocrine stress axis in the short-term, with this behavioral inhibition enhancing survivorship by reducing exposure to predators. However, tadpoles increase stress hormonal activity over a longer time frame, which induces adaptive changes in tail and body morphology. These changes either enhance survivorship by facilitating escape behavior or by providing a decoy (large tail) to deflect lethal predator attacks from the more vulnerable body.

Our research approach will use endocrinological measurements and modifications (i.e., blocking or enhancing the stress response with exogenous hormones/drugs) in conjunction with ecological lab and mesocosm experiments and dynamic state variable modeling. We seek to learn: 1) how the prey neuroendocrine stress response operates over time under a complex predation environment; 2) how stress hormones govern the expression and integration of the prey phenotypic response (i.e., behavior, morphology) in an ecological context; and 3) what the fitness consequences of this regulation are.

Location:  Successful candidates will join a dynamic, interactive group of students, post-docs, and faculty at The Ohio State University’s Aquatic Ecology Laboratory (http://ael.osu.edu/) within the Department of Evolution, Ecology, and Organismal Biology (http://eeob.osu.edu/). 

Qualifications:  Successful applicants will be creative, motivated, and capable of working effectively both independently and in collaborative groups.  A bachelor’s degree in biology, ecology, or a related field is required.  Strong writing and quantitative skills are essential. A background in endocrinology or computational modeling also would be useful.

Stipend: ~$2,325/month plus full tuition waiver and health benefits. Full Graduate Research Associates (GRA) support exists for ~2.5 years, with opportunities to teach (if so desired). Graduate Teaching Associate (GTA) support also exists for those interested in staying longer to complete a PhD.  

How to apply: Applications for this position are due by January 15, 2017. In addition to applying online (http://eeob.osu.edu/grad/program-admissions), email Drs. Michael Fraker and Stuart Ludsin at apps.ael@gmail.com1) a letter of interest that briefly describes your educational and research background, as well as your research interests/goals; 2) a curriculum vitae that also includes your GRE and (if applicable) TOEFL/TSE scores; 3) an unofficial copy of your transcripts; and 4) contact information for three professional references. Put “Graduate Student Position” in the email subject line.

Undergraduate Opportunities

Stream ecosystem metabolism in the context of global change (Reykjavik, Iceland) Download.docx

A Research Experience for Undergraduates (REU) position is available with the Hood Lab for summer 2017 to study stream ecosystem metabolism in the context of global climate change and eutrophication. The REU student will participate in the NSF-funded project “Interactive effects of temperature and nutrient supply on the structure and function of stream ecosystems” at The Ohio State University and in Reykjavik, Iceland. 

The successful candidate will join an international group of ecologists examining the influence of temperature and nutrients on stream metabolism and nutrient cycling. This research takes advantage of the unique geothermal environment in Iceland. Streams in Iceland’s Hengill region exhibit wide variation in ambient water temps due to spatial heterogeneity in geothermal activity. Our research leverages this spatial heterogeneity in stream temperatures to 1) develop theory, grounded in ecological stoichiometry and metabolic theory, for predicting the response of stream ecosystems to climate change and eutrophication, and 2) conduct experiments to understand how the temperature dependence of ecosystem metabolism differs across time scales and nutrient regimes. The student will work as a part of our team in Iceland on collaborative fieldwork and experiments. He/She will also develop an independent project. 

Iceland Project Website: http://www.montana.edu/wcross/Research/Iceland.html

The ideal candidate should be interested in perusing a career in ecology, hard-working, detail orientated, and dedicated to his/her work. The student will start on June 1st, 2017 in Reykjavik, Iceland. We will provide a stipend of $500/week for nine weeks, round-trip transportation to Reykjavik, and support for lodging in Reykjavik.

Interested students should apply by Friday, February 24th, but applications will be accepted until the position is filled. Eligible students must be U.S. citizens or permanent residents. Students who have received their bachelor’s degrees and are no longer enrolled as undergraduates are not eligible. Applications should include an unofficial copy of transcripts, contact information for two academic references, CV, and a one-page statement describing your interest in the REU position, academic goals, and previous research experience. 

Please send applications and questions to: Lyndsie Collis (Masters Student, collis.21@osu.edu)
