Ph.D position aquatic ecology
Field of subject for the appointment: Ecology. Starting date: Starting date as agreed upon. Term and hours: The doctoral studentship is limited in time in accordance with the Higher Education Ordinance (Chapter 5, Section 7). The studentship is full-time. Placement city: Kalmar, Sweden. Since Linnaeus University is located in both Växjö and Kalmar, travel between the two may be required. Job description This project is funded by the Swedish Research Council and concerns vitamin deficiency in animals, with a primary focus on salmon and vitamin B1 (thiamine). All organisms need thiamine for essential cellular functions. The vitamin is produced mainly by plants and microorganisms, but because it is water‑soluble, it cannot be stored to any significant extent. In species such as salmon and seabirds, deficiencies have recently been discovered, causing behavioral disturbances and high mortality in their offspring. The problem threatens fish populations in areas such as the Baltic Sea, the North American Great Lakes, and along the U.S. Pacific Coast (read more about this environmental issue here: rconnect.usgs.gov/vanishing-vitamin-app/). Animals obtain thiamine through their diet or from their gut microbiota, but in top predators like salmon, it is unclear how large a role the gut microbiota plays compared with dietary intake. The project will investigate thiamine deficiency through laboratory experiments, field studies, and mathematical models, with the goal of understanding why the deficiency occurs. The project will also involve extensive collaboration with researchers in the United States and Norway. According to the Higher Education Ordinance a person appointed to a doctoral studentship should primarily devote himself/herself to his/her own studies. An appointee may, however, work to a limited extent with education, research, artistic development, and administration. However, before a doctoral degree has been awarded, duties of this kind may not comprise more than 20% of a full-time post. Requirements A person fulfils the general entry requirements if they: have been awarded a degree on second-cycle level, completed the requirements for courses comprising at least 240 credits, of which 60 credits on second-cycle level, or in another way, in Sweden or abroad, has acquired principally equivalent knowledge. Specific entry requirements documented knowledge in ecology or biology good proficiency in English Assessment criteria These qualifications are considered merits in the assessment for the position: Master’s degree or equivalent experience in aquatic ecology or another closely related field Experience in: Scientific publishing Fish physiology Measurements using HPLC (high‑pressure liquid chromatography) Sampling and experiments involving fish or aquatic systems Mechanistic laboratory experiments Molecular and microbiological methods Matlab and/or R software Statistical analyses, such as multivariate statistics and linear mixed models General fieldwork experience Working independently and in teams Driver’s license for a car The studies are conducted within a research group where collaboration and flexibility are highly valued. In the overall assessment of qualifications, particular emphasis is placed on the applicant’s potential for a successful research career.
