Location: University of Saskatchewan, Saskatoon, Canada.

Supervisors: Dr. Philip McLoughlin, University of Saskatchewan, Saskatoon, Canada.

Deadline to Apply: Contact by Oct 25, 2018

Salary: Dependent on internal Scholarship (U of S Dean’s Scholarship Opportunity).

Start date: January 1st 2019 or May 1st 2019 (negotiable).

Project: We are looking to recruit a PhD student to contribute to our long-term, individual-based study of feral horses on Sable Island (Nova Scotia, Canada) initiated in 2007. There are several opportunities for the student to develop exciting thesis chapters and papers, including those based on linking horse survival and reproduction to grasslands enriched by sea-to-land nutrient transfers by seals; developing a fuller understanding of the role of horses in nutrient flows on the island with consequences for island biogeography (including theory); understanding the critical role of density and intraspecific density-dependent processes in population dynamics (from an individual-based perspective); and other fundamental questions of population ecology, life history, behaviour and sociobiology, parasitism, conservation, and evolution. We are particularly looking for mature M.Sc. students that are interested in developing a Ph.D. program that will contribute to and make use of and lead the archiving of the long-term data set the lab is collecting on the life histories of the horses on the island (>1000 life histories in the database, which is now one of the largest for a large vertebrate in the world). Sample sizes are large, with ~500 horses alive on the island as at Aug 2018. Next summer will be the 12th year of data collection, which includes summer censusing and identification of all individuals on the island using digital photography, and documentation of individual life histories with the goal of constructing whole-island pedigrees (the latter, and all molecular ecology questions, are being addressed by collaborator Dr. Jocelyn Poissant, at the University of Calgary). The student’s overall program will be a collaborative project benefiting from close interaction with the Poissant lab, with other opportunities to collaborate on campus or at other universities (e.g., Alastair Wilson lab at Exeter).

The student will spend up to 2 months on Sable Island each summer for fieldwork. Daily tasks, shared by the entire research team, will include walking censuses and photography of horses, collection of samples, laboratory work, identification of individuals from digital photographs, and database management. Students visiting Sable Island must work well in teams, deal well with life in a remote research station, be able to travel by small airplane, fishing trawler, helicopter, or frigate, and be reasonably fit as walking censuses require lots of hiking. Courses on first aid and driving all-terrain vehicles will be provided prior to fieldwork.

While all applications are welcomed, this position is scholarship-dependent; hence, preference will be given to Canadians who are competitive for a U of S Dean’s Scholarship and/or an NSERC scholarship. This will require M.Sc. publications and exceptionally good grades (GPA > 3.8) and a track record of past awards.

To apply send an email titled SABLE ISLAND PHD 2018 to

  • A short summary of research interests
  • Copies of your publications and description of role in these papers
  • A current CV
  • PDFs of undergraduate and graduate transcripts
  • The names and email addresses of 2 or 3 potential references

MSc opportunity, rattlesnake road-ecology work in British Columbia

We anticipate an opening for an MSc student continuing work on the road-ecology of a population of Western Rattlesnakes in the Okanagan valley of British Columbia.   We are looking for someone with a genuine, demonstrated interest in animal ecology, rather than solely a fascination with snakes.   We anticipate an early-April start date in the field, although there likely will  be opportunity to do some advanced work (with pay) prior to the spring emergence of snakes.

Inquiries and/or statements of interest from prospective students should be directed to Karl Larsen at Thompson Rivers University.   Following that, an unofficial copy of transcripts along with a Cv (providing references) will be needed.

I am on sabbatical from July 2018 – June 2019, but will be recruiting several Ph.D. and M.Sc. students to start when I return. My lab studies the ecology of plants and their natural enemies (herbivores and pathogens) in Ontario and elsewhere. Recent work has centred on the effects of insects and soil pathogens on non-native species, and whether damage depends on latitude, population isolation, and other factors. I’m also planning a new project studying factors setting northern range limits of invaders. Information on our research can be found at my home page:

We are a thriving department at a leading research institution, with excellent resources and many opportunities for interaction and collaboration. All graduate students are guaranteed a stable minimum income, currently $26,750 from a variety of sources, which provides for tuition (ca. $8500) and living expenses ($18,250). Additional support is available for research and conference travel. Information on application procedures and our tri-campus graduate program can be found at We will be accepting new applications beginning in November 2018, and will begin to review them in January 2019 for start dates in the summer or fall of 2019.

Location: University of Guelph and Hólar University College, Iceland. Field work occurs in the lava caves around Lake Myvatn northern Iceland.

Advisors: Dr. Moira Ferguson, University of Guelph, Guelph, ON Canada and Dr. Camille Leblanc, Hólar University College, Iceland.

Numerous ecological and evolutionary processes contribute to the generation of biodiversity, and the complexity of their interactions has presented a challenge to our understanding of nature. Our knowledge of the roles of development, natural selection, genetic drift, and gene flow in shaping biodiversity is complicated by the spatial and temporal variability inherent in natural systems. A powerful approach to better understand such processes involves monitoring wild populations over generations and obtaining data including pedigrees, phenotype, and fitness, so that we can directly infer evolutionary parameters, particularly those describing selection and genetic variation. We are seeking a talented MSc student to apply such an approach to wild populations of Icelandic Arctic charr, in order to further our understanding of the complex interplay among genes, phenotypes, and ecology, in natural environments.

The successful MSc student will test important microevolutionary theories with individual-based phenotypic records, molecular genetic (SNP) data, and ecological data from 19 populations of Arctic charr residing in a spatially replicated system of lava caves in the Myvatn area of northern Iceland. The monitoring of these populations began in 2012 and provides an impressive long-term dataset for novel insights. Advanced analytical techniques will be used to understand spatial and temporal patterns of genetic variation, natural selection, and ecological covariates. The student will be based at the University of Guelph with Prof. Moira Ferguson but will spend time at Hólar University College with Dr. Camille Leblanc (including annual fieldwork). Our ideal candidate will have interests in evolution, ecology, and genetics, and will have strong quantitative skills – necessary for the advanced analytical techniques used in this field. The student will be able to work independently and as part of a larger team, both in the laboratory and in the field.

The project is part of a long term collaboration between the University of Guelph, Canada (Prof. Moira Ferguson), Hólar University College (Prof. Bjarni K. Kristjánsson, Prof. Skúli Skúlason and Dr. Camille Leblanc), the University of Iceland (Prof. Sigurður S. Snorrason, and Prof. Arni Einarsson), EAWAG, Switzerland (Dr. Katja Räsänen), and the University of St Andrews (Dr. Michael Morrissey). The project is funded by The Icelandic Science Foundation (Rannis) and NSERC (Canada). The position will be filled as soon as a good candidate is found (target date 1. May 2018). The funding for the graduate student positions is sufficient to cover living costs and University of Guelph tuition fees for Canadian citizens or permanent residents.

Applicants should send an application letter with a max. 1 page statement of research interests and relevant experience, curriculum vitae, copies of academic qualifications including copies of unofficial transcripts and the names and e-mail addresses of three referees, as a single pdf file to Dr. Moira Ferguson (

For further information contact Dr. Moira Ferguson, Professor at the University of Guelph.


The Ricciardi Lab at McGill University ( is recruiting a graduate student at the PhD level to investigate how physical environmental conditions affect the success and impact of zebra mussel invasions. This is a fully funded position for four years.

The zebra mussel has recently invaded a southern Quebec lake, Lac Memphrémagog (100 km southeast of Montreal) and threatens to spread to other lakes in the region. These lakes vary in water chemistry and other limnological conditions that likely mediate the maximum abundance, distribution, and impact of the zebra mussel. We are looking for a student to investigate these relationships by conducting lab experiments, field studies, and empirical modelling. Another major focus will be to investigate the effects of an expanding mussel population on invertebrate diversity and food webs in these lakes.

McGill has a field station on Lac Memphrémagog. Our students are members of an interuniversity research centre in Quebec (GRIL) and interact with limnologists and ecologists in the Biology Department at McGill, as well as national and international collaborators that have expertise in invasion ecology. Our students also have the opportunity to take a unique summer NSERC training program in lake and fluvial ecology ( and a graduate-level course on invasion ecology at McGill.

The candidate will have completed a BSc Honors or MSc degree by Dec 2018, and have independent research experience and field training in freshwater or marine ecology. Owing to funding requirements, we are directing this ad to Canadians (or permanent residents in Canada); however exceptional international candidates will also be considered, if they are deemed likely to qualify for a scholarship. Applicants must meet the requirements of the graduate program of the Department of Biology ( The preferred start date is January 2019, but a later start date to begin field work before July 2019 might be possible.

Strong candidates should apply as soon as possible. The deadline for applications is September 10, or until a candidate is chosen. Applicants should provide:

  • An up-to-date c.v.
  • University Transcript(s) (e.g. a scanned copy)
  • Names and contact information of at least two referees,
  • A short (~1 page, single spaced) statement of research interests and relevant experience.

Send your application, as a single combined pdf if possible, to Prof. Anthony Ricciardi ( The student we select must apply to the Biology department by October 15 for admission into the graduate program in January 2019.

Graduate student opportunity in Ecosystem Ecology at Memorial University

The Ecosystem Ecology Lab at Memorial University of Newfoundland is recruiting graduate (MSc and/or PhD) student(s) to study the impacts of consumers on ecosystem functioning at local and regional extents. Specifically, we are looking for a student(s) to i) develop spatial ecosystem ecology theory for consumer impacts within and across ecosystems and ii) conduct experiments and observational studies in our boreal study systems. Our lab is actively developing and testing predictions from spatial ecosystem ecology theory using moose (Alces alces) and Atlantic salmon (Salmo salar) as case studies. Moose were introduced to the island of Newfoundland in the early 1900s and now the island sustains ~120,000 individuals and the highest densities of moose on the planet. Moose are having large impacts on forest and small stream ecosystems in Newfoundland. Atlantic salmon are a native anadromous and iteroparous fish found in streams across the island of Newfoundland. Salmon are an important biotic vector for the flux of nutrients between freshwater and marine ecosystems. Please visit our lab website to learn more about our research (

Memorial University of Newfoundland is the largest university in Atlantic Canada with ~18,000 students (~3,200 graduate students). The Department of Biology at Memorial is diverse with ~30 faculty and ~100 graduate students. You can find out more about the department, graduate studies application procedures and funding at: The position(s) come with a guaranteed stipend but interested students should also visit the Natural Sciences and Engineering Research Council of Canada for information on postgraduate scholarships:

Memorial’s main campus is in St John’s, a city of ~ 250,000 people on the Northeastern point of the island of Newfoundland. Newfoundland is a mecca for outdoor enthusiasts with excellent access to cycling, trail running and hiking (, whale and seabird watching, cross-country skiing, fishing, etc.

Students interested in joining the lab starting in September 2019 should send a cv, transcripts and statement of research interest to: We will begin considering applications on Sept. 15, 2018 until the positions are filled.
