Konkurs na stypendium naukowe dla doktoranta w Instytucie Nauk o Środowsku UJ

We are seeking for a highly motivated PhD student for a project entitled Experimental model of holobiont evolution: gut bacterial symbionts in bank voles selected for increased herbivorous capability (a part of NCN OPUS project Experimental evolution of physiological and behavioral adaptations in the bank vole: molecular background and alimentary system bacterial symbionts).


  1. MSc in life science (biology, ecology, evolution, zoology or related);
  2. interest in ecological physiology or microbiology and evolutionary biology;
  3. an experience in working with terrestrial vertebrate animals (preferably rodents);
  4. an experience in molecular or biochemical laboratory;
  5. analytical thinking, creativity and high motivation in learning new methods;
  6. good communication skills,
  7. good level of spoken and written English,
  8. admission in a PhD study program at the Institute of Environmental Sciences JU.

Task description

Symbiotic evolution played an important role at all stages of evolution of diverse life strategies. According to the “hologenome” concept, natural selection acts on the holobiont (host and associated microbes) rather than on animals alone. A unique opportunity to test the concept is offered by our artificial selection experiment on bank voles (Myodes glareolus). We observed that voles from lines selected for improved “herbivorous capability” had an altered composition of gut bacterial symbionts, even if the particular individuals had no contact with the special diet. We ask whether a) the difference in gut bacteria composition occurred in response to the short change of diet in parents, and was merely transmitted to offspring or b) the selected voles evolved genetically-based modifications allowing preferable hosting a modified bacterial community. The project consists of two main stages: 1) experiments on the voles (manipulation of diet, cross-fostering, measuring physiological traits and the size of internal organs, and collecting gut contents samples), and 2) molecular analyses of bacterial DNA in the samples, leading to description of the bacterial community and statistical analyses of its composition.

Deadline for application: 31 August 2017
