Position Description:
A postdoctoral position (up to two years) is available in the laboratory of Dr. Emily Moriarty Lemmon to collaborate on an NSF- funded project to study the effect of community interactions on evolution of male reproductive signals and female preferences in chorus frogs (Pseudacris) and the genetic consequences for speciation.
The postdoctoral scientist will lead a team of graduate students and field technicians to conduct fieldwork across the southeastern United States and perform behavioral experiments in a portable lab during the spring field seasons (approximately two months per year). Outside of the field season, the postdoctoral scholar will analyze behavioral data, genotype samples, and collect high-throughput sequencing data via anchored phylogenomics.
The postdoctoral researcher will have the opportunity to gain training in high-throughput data collection for phylogenomics and population genetics, analysis of phylogenetic data, bioinformatics, and behavioral ecology.
The ideal candidate will have field experience with frogs, experience conducting behavioral experiments, training in molecular biology, and computational experience. However, applicants with some combination of the above qualifications will also be considered. The start-date for this position will be Fall 2013 (exact date flexible), and salary will be competitive.
 
Interviews:
Dr. Lemmon will be attending the Evolution 2013 meetings June 21-26. Qualified applicants should specify whether they will be available for an interview during these meetings. Other applicants will be contacted as needed.
 
Minimum Qualifications:
· A Ph.D. in biology, molecular biology, or a related field with a focus on evolution
· Previous research experience and a strong publication record
· Extensive field experience, preferably with amphibians
· Ability to communicate clearly, work efficiently and independently, interact collaboratively, and lead a field team
 
Additional Preferred Qualifications: · Molecular biology and genetics training (e.g., phylogenetics, population genetics, phylogeography)
· Computational experience
· Experience in high-throughput sequencing
· Experience conducting behavioral studies
 
Application Deadline:
15 July 2013 (or until filled).
 
Start date:
Fall 2013 (exact date flexible up to December).
 
To Apply:
Application materials consisting of (1) a CV, (2) a statement of research interests and experience including how previous experience relates to the position description (2 page max), and (3) contact information for three references must be submitted to [url=mailto:chorusfrog@bio.fsu.edu]chorusfrog@bio.fsu.edu[/url]. Review of applications will begin June 21, 2013 and will continue until the position is filled. Informal inquiries are welcome. General information about the lab can be found at http://www.bio.fsu.edu/chorusfrog/index.html.
 
About Florida State University:
The successful applicant will be affiliated with the Department of Biological Science (http://www.bio.fsu.edu/) and will also interact with the Department of Scientific Computing (http://www.sc.fsu.edu/), and the College of Medicine (http://med.fsu.edu/). These groups collaborate extensively on evolutionary, behavioral, statistical, mathematical, genomic, and computational projects. The postdoctoral researcher will join this community of highly interactive research laboratories. Florida State University is located in capital city Tallahassee on the Florida Panhandle immediately adjacent to the Apalachicola National Forest, which is the largest national forest in Florida (nearly 900 sq. mi.). The forest borders the Apalachicola National Estuarine Research Reserve, which is one of the most productive estuarine systems in the Northern Hemisphere. The Apalachicola River basin contains the highest herpetofaunal diversity in the U.S. and Canada.
 
The researcher chosen will become part of the integrative laboratory groups of Emily Moriarty Lemmon and Alan Lemmon at Florida State University. The Lemmons collaborate extensively on projects involving collection of high-throughput phylogenomic data and on the development of new approaches to analysis of these data.

Ph.D. studentships in Amphibian Disease Ecology at James Cook University
 
We have funding from the Australian Research Council to support 2-3
exceptional PhD students who will work on a collaborative project
investigating amphibian disease in northern Australia. The disease
chytridiomycosis caused declines, local extirpations, and probably global
extinctions of many species of rainforest frogs in the Wet Tropics of
northern Queensland during initial outbreaks in the late 1980s and early to
mid 1990s. 
 
Our research group was the first to notice and document these declines, and
we have been studying them intensively for over 20 years.  We have
discovered that the interactions between the amphibian chytrid fungus
(Batrachochytrium dendrobatidis, Bd) and frogs are very complex.  Frogs’
behaviour affects their exposure to transmission of the infection, and
whether infected frogs simply carry the infection asymptomatically or
develop severe disease and die is affected by their choice of
microenvironment.  The effects of infections are also influenced by
antimicrobial secretions produced by frogs’ skins; our work on these shows
they may have evolved to increase the resistance of some populations to the
disease.  We are now also working on how the fate of infected frogs can be
modified by other microbes inhabiting their skins; we have shown that many
bacteria that live on frogs produce metabolites that fight Bd infections,
and it may be possible to probiotically manipulate them to reduce the
susceptibility of frogs in nature. 
 
Although many populations of frogs seem to be secure, because we do not as
yet understand how combinations of environmental factors affect the
vulnerability of populations to decline, it is entirely possible that a new
wave of population crashes could occur as weather and climate conditions
shift in the near future.  We are seeking students to participate in the
current phase of our work, which is focused on gaining a thorough
understanding of exactly what determines the tipping point beyond which a
mild, common infection becomes an epidemic outbreak of a fatal disease.
 
Our group has collaborative links with other researchers worldwide; these
have been highly productive of ideas and publications (see for example Prof.
Alford’s research portfolio and publication links, below), and mean that our
students have a range of opportunities available upon completion.  Recent
Ph.D. graduates in this field supervised by Prof. Alford are presently
academic or research staff or postdocs at New Mexico State University, the
Australian Museum, Plymouth University (UK), and the University of Colorado,
and have previously had postdoctoral positions funded by the Australian
Research Council, Vanderbilt University, the University of California,
Berkeley, and the University of Zurich, among other institutions.
 
Projects (field-based, laboratory-based, or both) will focus on any of these
topics:
 
1. Determining how chytridiomycosis affects populations by measuring fitness
and mortality rates of infected and uninfected frogs in populations
coexisting with endemic Bd infections.
 
2. Determining the relationship between frog microenvironment selection and
behaviour and fine-scale infection dynamics, to determine rates of
transmission and loss of infections, persistence of the pathogen in
environmental reservoirs, and what causes the population of pathogens on an
individual host to increase to the point of causing morbidity or mortality,
persist at lower levels, or disappear.
 
3. Determining whether frogs that have reappeared at sites from which they
were extirpated have recolonised or recovered in situ, and what changes in
the host-pathogen system have allowed them to do this.
 
4. Developing and performing preliminary tests of techniques that may favour
coexistence of frogs with the pathogen, and develop recommendations for
conservation actions.
 
Students should be available to start in February 2014 and will be based at
James Cook University in Townsville, Australia. We will only accept students
who obtain PhD scholarships, which cover living expenses (ca.
AU$24,600K/year) and tuition. Scholarships are highly but not impossibly
competitive, and are awarded to students with these minimum qualifications:
 
1. A first class Honours degree, or a Master’s degree with a research
component.  In exceptional cases they have been awarded to international
students with Bachelor’s degrees, research experience, and high-quality
first-authored publications.
2. Very good to excellent grade point average
3. Research experience, in the field or laboratory
4. Strong recommendation letters
5. A first-authored peer-reviewed publication (this is particularly
important for international students; applicants with publications are much
more likely to obtain scholarships, but if you excel in other areas this is
not a strict requirement)
 
The scholarship deadline for international applicants is 31 August 2013, and
for domestic (Australian) applicants is 31 October 2013.
 
Please send a CV, one page cover letter detailing your experience and
interests, contact details for 3 references, and unofficial transcripts to
[url=mailto:david.pike22@gmail.com]david.pike22@gmail.com[/url] with “PhD position” in the subject line. We will
narrow down the pool of interested students and work with 2-3 individuals on
their scholarship applications. TO BE CONSIDERED, APPLICATION MATERIALS MUST
BE RECEIVED BY 5 JULY 2013.
