Doctoral Researcher, Gut microbiome and thermal adaptations in wild birds

A Doctoral Researcher position is available at the Department of Biological and Environmental Sciences, University of Jyväskylä, Finland, in the group of Dr. Suvi Ruuskanen. The Doctoral Researcher will work in an ERC-funded project where the overarching aim is to understand the significance of the gut microbiome in thermal adaptations in birds within and across generations, and species. Starting date is August 2024 or as mutually agreed.

PROJECT DESCRIPTION

All animals on our planet carry microorganisms in their gut. The gut microbiome has recently been shown to be strongly linked to health in humans and model animals. However, we still have limited knowledge on how the gut microbiome can contribute to host adaptation, particularly in light of climate change. Interestingly, studies in vertebrate and invertebrate model organisms, and our own data in great tits (Parus major) suggest that the microbiome changes with temperature, and there is proof-of-concept data that this compositional shift in the microbiome occurs as an adaptive response to cold exposure. In this project the student will study the short-term flexibility of the gut microbiome to environmental (incl thermal) challenges, and its adaptive function in thermoregulation, using great tits as the model species. This will involve conducting novel experiments on wild-caught captive birds (e.g. manipulation of temperature and other stressors as well as microbiome manipulations), combined with physiological measurements in the lab, using a variety of bioinformatic and statistical tools.

DUTIES

The doctoral researcher position will involve conducting experiments with captive birds at the Konnevesi Research station, contribution to laboratory analyses (physiological and molecular), bioinformatic analyses of 16s rRNA and possibly other sequencing data, manuscript preparation and supervision of students.

QUALIFICATIONS

• We are seeking a highly motivated, innovative, productive person, who will be willing to gain experience both in the lab and in the field and contribute intellectually to the project development.
• Suitable candidates should have a Msc in ecology/evolution, (eco)physiology, molecular biology, microbial ecology or related field by the time of starting the position, and interest in host-microbiome research and bioinformatics.
• Experience in laboratory analyses or working with (wild) animals will be considered beneficial.

The duties, qualification requirements and language skills of a Doctoral Researcher are stipulated by the University of Jyväskylä Regulations and language skills guidelines. The MSc degree required for the position must have been completed before starting the position. Doctoral Researcher needs to be also enrolled in the doctoral programme which can be applied from the Faculty of Mathematics and Science after selection for the position.

WE OFFER

• Funding for 4 years in the doctoral program of the University of Jyväskylä.
• Supervision in all aspects of the work (from field to lab to computational skills), possibility to join workshops to improve specific skills in e.g. bioinformatics, data analysis.
• International, enthusiastic working environment (working language is English) in a friendly research group with a large collaborator network.
• Well-equipped research station (Konnevesi research station), labs and state-of-the-art scientific equipment, software, access to journals and scientific databases.
• Resources for travel to conferences or workshops abroad.

The Doctoral Researcher will be supervised by Dr. Suvi Ruuskanen and Dr. Charli Davies.

For further details, please contact Associate Professor Suvi Ruuskanen, suvi.k.ruuskanen@jyu.fi.

The Environmental Physiology lab (Environmental Physiology Lab | University of Jyväskylä (jyu.fi), led by Suvi Ruuskanen, research fields are at the intersection of environmental sciences, ecotoxicology and physiological, behavioural and molecular ecology, thus we are integrative biologists. We are broadly interested in the molecular and physiological mechanisms underlying organismal adaptation to environmental changes. These include, for example, physiology of stress and energetics, epigenetic and microbiome-mediated mechanisms. We also have passion for understanding transgenerational and developmental plasticity.
