Postdoc: Modelling Species’ Range Expansions in Marine Environments

Diary id: PAR 2020/216
Employment level: Fixed term
Location: Department of Marine Sciences
Apply by: 2020-08-31

The Department of Marine Sciences (http://marine.gu.se/english/) is Sweden’s most complete academic environment for marine research and education, and it is one of few such institutions in Europe. The Department of Marine Sciences, founded 2015, brings together expertise in physical oceanography, marine chemistry, marine biology, marine geology, and marine heritage conservation. Thus the department has excellent opportunities to meet future challenges in marine research and education. The Department of Marine Sciences is located with permanent staff in Gothenburg and at the research stations Kristineberg and Tjärnö on the Swedish west coast north of Gothenburg.

Subject area

Applied Physics/Theoretical Biology

Subject area description

Climate change related effects commonly induce changes in species distributions. Under a warmer climate it is expected that species distributions change to fit their optimal temperature range. Climate-induced movement will, in most cases, have demographic consequences, and populations at the front of the expansion wave will have low genetic variation. Earlier models show that at the front of an expanding population genetic diversity is controlled by local population size, migration rate, degree of fragmentation of the expanding population and strength of natural selection. However, many of the assumptions in the existing models are overly simple for most wild species (e.g. haploid species, fully sexual or fully clonal reproduction, non-overlapping generations, symmetric stepping-stone or Gaussian dispersal functions, and, in many cases, homogeneous and temporally stable environments). In the project in which the postdoc will work, we aim to deliver new and adequate modelling tools, with which it will be possible to analyze size, quality and structure of the available habitat (“green infrastructure”) needed to mitigate loss of genetic variation during species movements largely induced by human activities.

Empirical genome-wide genetic data are available for several marine species that recently (8000 years ago) expanded their distributions over the steep salinity gradient shaping the Baltic Sea ecosystem, each species with its current range margin at a specific position along the gradient. This postdoc project aims to address two questions: (i) How did expansion 8000 years ago change the genetic structure and content of the populations today, taking into account the impact of gene flow, habitat structure and reproductive biology of the species? (ii) What will happen with these already marginal populations under the increased stress from climate change (warmer and lower

salinity)? First, theoretical models will be constructed and iterated. Second, the models will be parameterized with empirical data for target species, and model results will be validated against the spatial patterns of genetic diversity within and between the populations of the target species. Thereafter the results will be used to try to predict future distributions of these species under different climate scenarios and habitat structure (e.g. availability of marine reserves and “green infrastructure”).

This project will be financed by a grant from a prestigious Swedish Research Council Formas awarded to Marina Rafajlović and Kerstin Johannesson.

Job assignments

The candidate will join an international team with both theoretical and empirical competences, working on the evolutionary biology of marine species including the genetics of recently expanded species in the Baltic Sea transition zone. The team is based at the Department of Marine Sciences, with permanent working places both at the research station Tjärnö Marine Laboratory, and at the campus in Gothenburg. Intense collaboration has been established with University of Sheffield for many years, and the project will be conducted in tight collaboration with Roger K. Butlin (University of Sheffield, Sheffield, UK & University of Gothenburg, Gothenburg, Sweden).

The candidate is expected, in collaboration with the rest of the team, to perform the modelling work on species’ range expansions including development of the mathematical model, implementing it using individual-based spatially-explicit computer simulations, and analyzing model results both numerically and analytically. The work also includes tests of the model by comparing model results with the available empirical data on present species’ distributions and their spatial genetic patterns using standard software and custom scripts, but also using novel scripts specifically developed within the team to ease and improve the model-data comparison. In addition, the candidate is expected to present the results of the analyses in manuscript(s) and at conferences, and communicate the findings at various dissemination activities. The candidate is also expected to take part in other research-related activities at the department, and within the research group in particular.

Eligibility

Qualified for appointment as postdoc is a person who has been awarded a PhD degree in a subject area relevant for the position no longer than 3 years ago. Relevant subject areas for this position are population genetics, theoretical biology, mathematics/physics, or equivalent academic disciplines. A candidate with a foreign degree that is judged to be comparable is also eligible.

Background knowledge in evolutionary biology is considered a strength.

The candidate should

have earlier experience with writing his/her own computer simulations in Matlab, and/or C/C++, and/or Mathematica (or equivalent), and/or experience with statistical analyses of genetic data in a population or evolutionary context. Experience with SLiM is considered an advantage.

Assessment

Scientific proficiency will be the primary criteria for the assessment of merits.

The scientific proficiency is assessed with a focus on the candidate’s capacity and earlier experience of working in the field of theoretical population genetics.

The assessment is based primarily on scientific publications and on participation in international conferences and workshops. The successful candidate will be chosen based on an overall assessment of proficiency and potential within the subject area, the potential and ability to independently carry out the duties of the position, and the abilities to communicate and cooperate with others.

PhD student in molecular biology: protein phase separation and aging

Diary id: PAR 2020/790
Employment level: Fixed term
Location: Department of Chemistry and Molecular Biology
Apply by: 2020-07-15

Recent studies found that different membraneless compartments can be formed in the cytoplasm through a process called phase separation. These phase separation processes ensure spatiotemporal control over diffusion-limited biochemical reactions. The formation of phase separation condensates is known to be sensitive to physical – chemical changes, such as pH levels, protein concentration, or cellular energy levels. Aging is known to cause cellular environment changes on levels of cytosolic pH, protein translation, ions, nutrients, amino acids. Whether these aging related changes directly lead to abnormal phase transitions remains to be elucidated. One of the main aims of this project is to uncover mechanisms underlying the interplay between the aging process and protein phase separation in the cell.

Beidong Liu group´s research interest is focused on deciphering mechanisms underlying the formation of membraneless originals (formed through protein phase separation) and their roles in aging and aging-related diseases by developing and applying novel high-content screening techniques using yeast (Saccharomyces cerevisiae) as a model system. The group is located on the medical campus, close to the Sahlgrenska Hospital in Gothenburg and interacts collaboratively with several local and international groups

Job assignments

The PhD student will be expected to carry out semi-independent research concerning the mechanisms underlying the interplay between the aging process and protein phase separation using yeast (Saccharomyces cerevisiae) as a model. The main assignments for the PhD student will be: Perform genome-wide screening experiments to identify novel protein phase separation targets, to genetically engineer target protein expressing strains, and to purify candidate proteins and evaluate their phase separation properties, to apply genetic, molecular biology and biochemistry approaches on deciphering mechanisms underlying the relationship between aging and protein phase separation.

Bioinformatics analyses of genomic data, or cheminformatics analyses of molecular structures may be included. Part of the task may also be to participate in developing experimental technology, e.g. for robotized high-throughput methods, or implementation of novel genetic engineering techniques.

 The recruited PhD student will participate in seminars and internal group meetings, and in addition interact with other research groups in the department or abroad.

PhD Position in Natural Science, specialising in Environmental Science (with focus on microbial ecology/ecotoxicology)

Diary id: PAR 2020/717
Employment level: Fixed term
Location: Department of Biological and Environmental Science
Apply by: 2020-08-31

At the Department of Biological and Environmental Sciences (BioEnv) we have teaching and research activities that stretch from the alpine ecosystem, through forests, cultivated land and streams, all the way into the marine environment. In these environments we study different levels of biological organization from genes, individuals and populations, to communities and ecosystems. We work within ecology, evolution, physiology, systematics and combinations of these fields in order to understand the impact of natural and anthropogenic changes of the environment.

The department is placed at three different localities: in Gothenburg Botanical garden, at Medicinarberget in Gothenburg, and at the marine research station-Kristineberg. The current position is placed at Gothenburg Botanical garden.

Project description

Aquatic biofilms are benthic communities of microorganisms (bacteria, cyanobacteria, algae, fungi and protozoa) that control many biochemical cycles in fluvial ecosystems, and at the same time are very sensitive to toxicants exposure. To date, the role of biofilms to biodegrade organic pesticides and reduce their toxicity in fluvial ecosystems is not well known. This PhD project aims to quantify the capacity of aquatic biofilms to degrade pesticides, to identify microorganisms associated with higher pesticides biodegradation rates and, to determine enzymes and genes that participate in the metabolic pathways of biodegradation. Thereby, this research will provide crucial inputs about the potential of aquatic biofilms for pesticides bioremediation in polluted rivers.

This project will be conducted with the support of an interdisciplinary research team including researchers at the home university, University of Gothenburg and Chalmers University of Technology. The research team has expertise in freshwater ecology, microbial community ecology/ecotoxicology, metagenomics and bioinformatics.


Job assignments

The main task is to conduct the PhD thesis work under supervision, which includes development of the PhD student’s methodology experience, analytical skills, and theoretical depth and breadth. Techniques and approaches used within the project include degradation kinetics tests with labelled pesticides to assess chemical fate, dose-response toxicity tests, microcosms experiments to assess adaptation and community effects upon exposure to organic pesticides and, microbial genomics to identify microorganisms associated with higher pesticides biodegradation rates, enzymes and genes that participate in the metabolic pathways of biodegradation. The applicant will combine field and laboratory approaches.

Third cycle education

Admission to third cycle education is aiming at a PhD in Natural Science, specializing Environmental Science. The education runs for four years of fulltime studies, containing three years of thesis work and one year of academic education (i.e. course work and literature studies). A selection of courses at the Department/Faculty is available, but national/international courses can also be selected.  Some teaching and/or course administration can be included which extends the contract to the same extent.

Eligibility

To be eligible for third-cycle studies, the applicant must meet both the general and specific entry requirements. A person meets the general entry requirements for third-cycle courses and study programs if he/she:
1. has been awarded a second-cycle qualification, or
2. has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or
3. has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

Project description                                  

We are looking for a highly motivated PhD student in marine chemical ecology. Chemical sensing is the key sensory modality in the ocean but we still know very little about it in marine plankton. What compounds are the signals? How can they be recognized and interpreted? How do they transmit between organisms? How do organisms and ecosystems respond? This project is centred around novel chemical alarm-signals between marine plankton, a group of lipids discovered in our lab named copepodamides. Phytoplankton sense copepodamides and respond with defensive traits such as toxin production, altered swimming behaviour, increased bioluminescence. The project will be tuned to the interest and background of the successful candidate. You could e.g. focus on the chemical aspects (structure elucidation of hereto unknown signalling molecules, field measurements etc), the biological (the effect of copepodamide signalling in cells, between organisms, and on the ecosystem level), or the physical (how do signalling molecules spread at the turbulent microscale?). Irrespectively, you are likely to work with different zooplankton and phytoplankton organisms and be involved in fieldwork on marine stations and research ships. You will also have access to a fully equipped chemical ecology lab including culture facilities and GC/LC-MS instruments.

Experience with motion analysis, image analysis, analytical chemistry, mass spectrometry, scientific writing, plankton ecology, social skills, and programming are meriting. The successful applicant will be self-motivated, solution oriented, curious and passionate about science. You should have a relevant exam in biology, chemistry, physics, or equivalent. We are a transdisciplinary group and welcome applicants from biology, chemistry and physics. The project is 50% funded by the Swedish research council (VR), and 50% departmental funded which allows for some more degrees of freedom than fully externally funded projects. Interested? Check out our homepage http://pelagial.se/, and feel free to contact us for further information.
