Post-doctoral opportunity: Tracing population linkages of stream gobies in
Hawaii using microchemistry UW-Madison Center for Limnology, University of
Wisconsin
The McIntyre lab group in the Center for Limnology at the University of
Wisconsin seeks a post-doc to use the microchemistry of fish otoliths to infer
individual movement histories and population connectivity. The work is part of a
larger team project to quantify linkages among populations of at-risk stream
gobies across the Hawaiian archipelago by merging population genetic, field
assessment, and environmental chemistry approaches. PIs include Mike Blum
(Tulane), Jim Gilliam (NC State), and McIntyre. Otolith work is conducted in
close collaboration with Nate Bickford (U of Great Falls).
The post-doc will lead the collection, preparation, and chemical analysis of
otoliths as well as subsequent statistical analysis and manuscript preparation.
This will include samples from conspecific gobies collected from dozens of
watersheds across five islands, yielding unusually rich biogeochemical datasets.
Two types of chemical analyses are of interest: trace element profiles (pilot
work included 18 isotopes of 13 elements) by LA-ICP-MS to characterize the
chemical environment during natal, larval, and post-settlement periods; and O
isotope ratios by ion microprobe to reconstruct thermal histories during larval
and post-settlement periods. Results will be interpreted in evolutionary,
population, landscape, and conservation contexts.
The expected task list has five components: joining the field team for roughly
three months of intensive sampling throughout the Hawaiian archipelago in spring
2011; preparation and analysis of otoliths; statistical analysis of the 2011
dataset as well as an extensive pilot dataset; preparation of multiple
manuscripts on otolith results; and contribution to team manuscripts
synthesizing overall results of the project. Additional opportunities for
involvement in other otolith-based projects in my lab group also may be available.
Experience in both field work and environmental chemistry, a successful
publication record, and a positive, team-oriented attitude are essential
qualifications. Candidates with specific experience in the preparation and
elemental/isotopic analysis of fish otoliths (or other carbonates) are
particular encouraged to apply. The successful applicant must be able to work
independently on otolith analyses, but also contribute to the esprit de corps of
my lab group and the broader project team. Please see my website for more
project details and lab philosophy: http://limnology.wisc.edu/personnel/mcintyre/
The position will begin on or around 1 February 2011, and funding is available
through at least May 2012 (pending performance). A competitive post-doc salary
will be offered, including UW-Madison benefits package. Aside from field work,
the position will be based at the Center for Limnology of the University of
Wisconsin in Madison. The Center' is home to a world-renowned aquatic sciences
research group, and features a vibrant atmosphere in which collegial
interactions among faculty, staff, post-docs, and graduate students are the
norm. Madison is widely recognized for its high quality of life, lively culture
and arts scene, and easy access to natural areas. Costs of living are moderate,
and public buses or bicycle paths are easy transportation options.
To apply, please submit a letter of interest, CV, three relevant reprints (in
pdf form), and phone & email addresses of three references to Denise Karns
([email protected]). The letter of interest should explicitly address relevant
experience/expertise in both field and lab settings. Review of applications will
begin Dec 26 and will continue until the position is filled. Any questions about
the position may be directed to Pete McIntyre ([email protected]).
