Postdoc: Temperature variation and endangered aquatic species

We are seeking applications for a Postdoctoral Fellow position to work on temperature variation and extinction risk.  It seems likely that the transient dynamics of small populations far from a stable age or size distribution may interact with autocorrelated environmental variation in ways that could significantly increase the extinction risk. In collaboration with National Research Council Canada (CNRC-NRC) and Fisheries and Oceans Canada (DFO), the postdoctoral researcher will examine the impact of autocorrelated temporal variation on the transient dynamics of structured population models of SARA-listed aquatic species. The position will require the analysis of temperature threshold probabilities and autocorrelation in addition to population modelling.

Candidates must hold a PhD in an appropriate discipline (e.g. Ecological modelling, Mathematical Biology, Statistics of Ecological Systems) at the time of appointment and have experience working in a research environment. The anticipated start date is January 2019. This is a one year position with possibility of being renewed for a second year (contingent on funding).  The salary is $42,000 plus health benefits. More information is available at,

To apply, please send the following to Dr. Kim Cuddington via email: 1. A complete CV, 2. A statement on how the applicant can fit the position (max one page), 3. unofficial transcripts, 4. Names and contact information for three referees

Review of applications will begin immediately and continue until a successful candidate is identified.


Postdoctoral research opportunity, Aquatic Microbial Ecology / Carbon Biogeochemistry

Start date: Winter – Spring 2019

Location: Université du Québec à Montréal, Canada

A postgraduate fellowship is available in the Aquatic Ecology Group of the Université du Québec à Montréal (UQÀM), to carry out research at the interface of aquatic microbial ecology and biogeochemistry, associated to the NSERC-funded Research Chair in Carbon Biogeochemistry in Boreal Aquatic Systems. The research project will focus on issues related to the assembly and functioning of freshwater aquatic bacterial communities and their links to environmental factors, and will take a whole network approach to reconstruct the taxonomic, phylogenetic and functional microbial successions that occur along the aquatic continuum, from soils to the sea through interconnected rivers and lakes.

The research may also explore the chemical succession that occurs in the molecular structure and reactivity of the dissolved organic carbon pool along this same aquatic continuum, with the ultimate objective of determining the connections and interactions that may exist between these two key components of all aquatic ecosystems. The project may involve highly spatially resolved sampling along the aquatic continuum and across gradients and ecotones, focusing on lakes and rivers in the boreal region of Québec, and will apply a combination of high-throughput sequencing and microarray technologies, metabolic and physiologic measurements of bacterial communities, and advanced analytical approaches to characterize the molecular composition of DOM.

We seek a highly motivated candidate who is ready to embrace a multidisciplinary challenge and to work in a highly collaborative team context. Our students and postdocs are part of a dynamic and culturally and scientifically diverse aquatic group in the Département des sciences biologiques of the UQÀM, with expertise ranging from nutrient and C biogeochemistry, genomics and bioinformatics, microbial, plankton and ecosystem ecology. Those interested should send a letter of introduction, academic resume, and the names of two references to Paul del Giorgio (, 514-7957983). E-mail enquiries for further information are welcome.

POSTDOCTORAL FELLOWSHIP OFFER, Department of Natural Sciences – Université du Québec en Outaouais (UQO)

Spatiotemporal Individual-Based Modelling of the St. Lawrence Estuary Beluga Population

Project background and objectives

St. Lawrence Estuary beluga population is currently listed as endangered under the Species at Risk Act of Canada. It is also listed as threatened under the Quebec Act Respecting Threatened or Vulnerable Species. Several threats related to navigation activities in the beluga’s critical habitat limit its recovery, including disturbance and exposure to boats’ underwater noise. Mitigating such navigation impacts requires tools to evaluate the performance of potential measures before taking action. The postdoc fellow’s project is part of a broader research program that aims at building a multiagent simulator of boat and whale movements in both the Saguenay and St. Lawrence Rivers to assess the effectiveness of potential mitigation options. The broader goal of the research program is to support a collaborative process to enhance the protection of the at-risk St. Lawrence Estuary beluga population in its critical summer habitat.

The postdoc fellow’s project aims at building calibrated algorithms that accurately simulate belugas’ individual movements by reproducing data-extracted statistical patterns. Several concurrent hypotheses currently exist regarding beluga movements, social dynamics, and responses to the presence of boats in their critical habitat. These hypotheses will be made explicit by the selected candidate. The related uncertainties will be translated into the proposition of concurrent movement algorithms. Statistical patterns will need to be identified at different scales (individual, group and population) and extracted from several datasets provided by collaborators. These patterns will allow to calibrate the movements algorithms and assess their performance using the Pattern- Oriented Modelling approach. Based on a literature review, the selected candidate will propose a series of beluga-specific indicators of navigation impacts (e.g. masking/communication space, disturbance, collision risks). These indicators will be used to assess the performance of mitigation scenarios using the final simulator that will couple a valid beluga IBM with an existing model of boat movements. The development of beluga’s movement algorithms will be based on behavioral ecology theories and developed in collaboration with researchers who have been studying belugas since the early 80’s. Although this modelling project does not require any data collection in the field, the selected candidate will work in close collaboration with researchers from Group for Research and Education on Marine Mammals (GREMM), Fisheries and Oceans Canada, and Saguenay–St. Lawrence Marine Park, and will have the opportunity to take part in their field campaign.

The desired candidate will show dynamism, motivation, intellectual curiosity and creativity, ability to work independently and as part of a team, along with a great sense of initiative. He/She will be encouraged and supported to travel for scientific communications (conferences, workshops), meetings with partners and stakeholders. The project funding is provided by the Government of Quebec. The selected candidate will be required to participate in the production of deliverables for the Ministry for Forests, Wildlife, and Parks and Ministry for Maritime Affairs on a yearly basis.

RANK: Post-doctoral fellow
SALARY RANGE: $45,000–$55,000 per annum (plus benefits), commensurate with qualifications and experience
PROJECT OVERVIEW: We are using a genome-wide association study (GWAS) in combination with linked-read whole-genome resequencing in 30 males and 30 females to test for and identify the genetic basis sex determination in sea lamprey. Sex determination mechanisms in fishes are highly variable, ranging from genotypic (GSD) to environmental (ESD) sex determination. Male-biased sex ratios under conditions of high population density or slow growth have led to suggestions of ESD in lampreys, but there is no conclusive evidence in lampreys of ESD, and no fish species with exclusively ESD are known. Understanding the genetic basis of sex determination in lampreys is important given their phylogenetic position as one of only two surviving groups of jawless vertebrates. Furthermore, the sea lamprey is a significant pest in the Laurentian Great Lakes and genetic manipulation of sex determination could be a powerful tool for control. The Principal Investigators on the project are Drs. Margaret Docker and Colin Garroway (Department of Biological Sciences, University of Manitoba) and Dr. Alison Wright (Department of Animal and Plant Sciences, University of Sheffield).
JOB DESCRIPTION: The primary task of this position will be to test for a genetic basis for sex determination in the sea lamprey. However, the PDF will also have the opportunity to develop and pursue his or her own research questions within the context of sea lamprey evolutionary genomics.
  • To undertake research on the genomics of sex determination in sea lamprey. To contribute significantly to experimental design, data interpretation and statistical analysis.
  • To trial new techniques and assay systems as required and keep abreast of the research literature relevant to the project.
  • Disseminate research through publications in peer reviewed journals.
  • To attend and contribute to research seminars, departmental meetings and international conferences.
  • Carry out administrative roles as required, e.g. organising physical or remote meetings with collaborators, arranging travel to consortium meetings.
  • Perform professional activities such as refereeing papers, editing journals, refereeing research grants, external examining, organising conferences, committee membership and involvement with professional bodies on accreditation.
  • PhD in evolutionary biology, computational biology, or genetics or successful PhD viva at commencement of contract.
  • Proven ability to process and analyse next-generation sequencing data. Experience with Chromium 10X technology is desired but not essential.
  • Proficiency with analysis software and programming languages, as well as ability to write or adapt scripts and pipelines for in silico genetic analysis.
  • Ability to work both collaboratively and independently
  • Well-developed leadership, management and influencing skills
