Modeling ecology/evolution of a plant pathogen

PhD position: Modeling ecology/evolution of a plant pathogen, ETH Zurich

***The project***

will explore population dynamics of Zymoseptoria tritici, an important 
fungal pathogen of wheat, using eco-evolutionary modeling and field/lab 
experimentation.

Plant diseases often cause serious yield losses in agriculture. Current 
chemical and genetic technologies used to manage plant diseases are 
highly vulnerable to pathogen evolution and are not sustainable. 
Pathogen evolution is facilitated by the genetic uniformity underlying 
modern agroecosystems. Thus, there is an urgent need to develop new, 
efficient and sustainable ways to control plant diseases.

This PhD project intends to make an important contribution towards 
achieving this goal.  The first phase aims at comprehensive 
characterization of both epidemic and evolutionary factors of the 
pathogen by combining eco-evolutionary modeling, field/lab experiments 
and genome sequence analyses. In the second phase the models will be 
used to predict the rate of pathogen adaptation to disease control and 
propose optimal spatio-temporal patterns for applications of fungicides 
and resistant host varieties that can disrupt pathogen adaptation.

***Working conditions***

Plant Pathology group at the Institute of Integrative Biology, ETH 
Zurich offers a creative, collaborative research environment and 
excellent infrastructure (www.path.ethz.ch). Salary is approximately 
48000 Swiss francs per year. Zurich is a vibrant, international and 
green city.

The PhD project is funded for three years by the Ambizione grant from 
the Swiss National Foundation with a possibility of extension for the 
fourth year.

Unique training in mathematical modeling, bioinformatics and field/lab 
experiments increases chances to find a job in academia, industry or 
governmental agencies.

***Requirements***

---Master's/diploma in a quantitative discipline (e.g. physics, 
mathematics or computer science), biology or agricultural/environmental 
sciences.

3 Ph.D. positions available

We have two major projects starting at the University of Nevada, Reno
with 3 Ph.D. positions available.  Please pass this announcement on to
potential candidates.  Thank you!

PhD Graduate Research Assistantship in Neotoma evolutionary genetics
and ecological adaptation.

A Ph.D. Graduate Research Assistantship is available to study ecological
adaptation and hybridization between two species of woodrats (genus
Neotoma) in California. The goal of the project is to identify how
diet-based ecological adaptations may influence aspects of pre- and
post-zygotic isolation. The student will play a large role in the design
and implementation of field and laboratory-based studies that include
analysis of gene expression and microbiome changes in pure and hybrid
genotypic classes as they are exposed to chemically-distinct, field-based
diets. The student will also participate in a high school outreach program
focused on teaching genetics, ecology and evolution. Candidates should
be creative and highly motivated with strong writing and communication
skills. Candidates must have a B.S. (and preferably an M.S.) in biology
or a closely related discipline. Candidates must have field experience
(preferably with small mammals), ability to work under rigorous field
conditions and lead field crews under their supervision, some genetics
laboratory experience and interest in science education.

Ph.D. Graduate Research Assistantships (2). Pygmy rabbit ecology,
demography, and landscape connectivity.

Two Ph.D. research assistantships are available at the University of
Nevada-Reno on a project focused on building a quantitative understanding
of the ecology, demography and population connectivity of the pygmy rabbit
(Brachylagus idahoensis) in Nevada. The pygmy rabbit is a sagebrush
specialist that is broadly (but non-continuously) distributed across
the Great Basin. Like other habitat specialists, the pygmy rabbit is
expected to be particularly vulnerable to climate change. Further,
because of the predicted loss and degradation of sagebrush ecosystems
over the coming decades, it is critically important to identify key areas
that may serve as refugia or movement corridors for pygmy rabbit and other
sagebrush obligates while large, relatively intact sagebrush tracts remain
available for study. The goal of this project is to quantify population
dynamics and dispersal/colonization capabilities of the pygmy rabbit
in Nevada to develop a more complete view of the habitat and landscape
characteristics that sustain local and regionally connected populations.
Although both students will be expected to collaborate extensively, we
expect that one Ph.D. student will focus primarily on landscape genetics
(advised by Dr. Marjorie Matocq), while the other student will focus on
demography and population modeling (advised by Dr. Kevin Shoemaker). Field
research for both students will include trapping and marking pygmy rabbits
and collecting tissue samples at numerous sites in Nevada. Laboratory work
for the landscape genetics student will include generating genetic/genomic
datasets to quantify reproductive success and relatedness within
populations and genetic connectivity among populations. "Laboratory" work
for the population ecology student will include estimating vital rates
such as fecundity and survival from capture-mark-recapture data, using a
geographic information system to identify suitable habitat patches and
modeling functional connectivity, and constructing spatially explicit,
individual-based population models. Applicants should be hard-working,
self-motivated field biologists prepared to work under rigorous field
conditions and able to lead field crews under their supervision. Both
candidates should have field experience with small mammals, basic
literacy in data management and statistical analysis, and strong writing
and communication skills. The genetics student should have genetics
laboratory experience, and the population ecology student should have
proficiency in the use of geographic information systems and competence
with computer programming is highly desirable. Driver=A2s licenses are
necessary for both positions. Applicants must have a B.S. (and preferably
an M.S.) in biology or a closely related field.

To apply for one of the above positions, please submit the following
as a single PDF email attachment: a letter stating your qualifications
and career goals, CV, transcripts, GRE scores, and contact information
for three references (not letters).  Review of applications will begin
November 20, 2015 and will continue until the positions are filled.
Send application to Dr. Marjorie Matocq, Department of Natural
Resources and Environmental Science, University of Nevada, Reno,
Reno, Nevada 89557 (775-784-4621; mmatocq@cabnr.unr.edu). See the

Ecology and Sociobiology of a Wolf-Ungulate Predator-Prey Game

Ecology and Sociobiology of a Wolf-Ungulate Predator-Prey Game

Start Date: September 2015 (flexibility exists for exceptional candidates)
We have a fully funded PhD position for a student interested studying
the spatial ecology and sociobiology of predator-prey dynamics with
links to population and disease ecology in a wolf-ungulate community.

System: Riding Mountain National Park (RMNP) in Manitoba is among the
best-studied large mammal communities in Canada. Peer-reviewed research
has been produced from the RMNP system for the last 80 years: from Green
(1933) and Banfield (1949) to Paquet (1990s) and our recent work. RMNP
is a rich system within which to simultaneously ask fundamental and
applied ecological and evolutionary questions.  Over the coming years
and primarily using GPS collars, this project will see all wolf packs
and >80% of the elk monitored in one of RMNP��s elk subpopulations,
creating a near-perfect spatial and temporal picture of predatory-prey
interactions between wolves and their primary prey. Furthermore, the
successful applicant will have access to our considerable collection
of historical individual- and population-level data on space use and
population densities of elk, moose, white-tailed deer and wolves (see our
papers for examples). As a result, this project will provide excellent
opportunities for both academic and professional advancement. Because
it is a PhD-level project, the successful applicant will be expected
to develop her or his own ideas and research plan in collaboration with
the research team.

In the Wildlife Evolutionary Ecology Lab we feel strongly that novel
biological ideas are derived from interacting directly with our study
species and system, and the successful applicant will be expected
to spend considerable amounts of time in the field, supported by an
excellent team of biologists at RMNP. The successful applicant will be
required to actively investigate kill- and den-sites and to fly telemetry,
while simultaneously working with existing data. At the PhD level, this
will require an exceptional applicant who can both be in the field and
continue to actively analyze and write throughout their program.

Qualifications: In addition to a MSc that complements this research,
applicants should have five main qualities: (1) a passion for ecological
and evolutionary theory; (2) an aptitude for and commitment to research
in the field �V in all seasons; (3) well-developed quantitative skills
in GIS, statistical programing in R, and experience or an interest in
modeling; (4) a track-record of publishing their research in reputable
peer-reviewed journals; (5) and foremost, evidence of collegiality.

Team: This research is part of a larger collaborative program studying
predatory-prey dynamics in wolf-ungulate systems in southern Manitoba. As
a result the successful applicant will be a part of a research team that
includes Parks Canada biologists, Manitoba Fish and Wildlife ecologists,
a MSc student in RMNP (start date May 2016), and another PhD student
studying wolf-ungulate dynamics in eastern MB. This collaborative
opportunity will permit the right applicant to participate in projects
and publications in addition to their own core research.

Wildlife Evolutionary Ecology Lab (http://ericvanderwal.weebly.com/):
We are a question-driven research group; one of a number of productive
and dynamic research groups in ecology, evolution, and animal behavior
at MUN. We bridge fundamental and applied questions in evolutionary,
behavioral, population, and wildlife ecology, particularly with social
ungulates. RMNP has been one of our keystone and must productive
research systems and this new program aims to further advance our work
on density-dependent resource and space use, social and group dynamics of
ungulates now with a finer-scale understanding of the predatory-prey game.

To apply please send a letter of interest, CV, and transcripts
(unofficial) to eric.vanderwal@mun.ca. Although the position is
fully funded, students will be encouraged to compete for internal and
external funding; higher GPAs and a history of publications improves
competitiveness. The competition will remain open until the position
is filled.
