CREAF is seeking a field assistant for the FISHINDROUGHT project (Under the surface: uncovering the role of individual differences in how fish populations cope with severe droughts) with grant number EC-92592R-22 and financed by the National Geographic Society.

Dr. Jolles, Severo Ochoa researcher at CREAF, and our research is aimed to better understand and predict how freshwater fish cope with droughts, an issue that has become very pressing due to the increasing effects of human-induced global change. In our work we combine behavioural experiments with field surveys and environmental monitoring to uncover in detail how drought affects the movements and distribution of freshwater fish, how that is linked to phenotypic variation, and what consequences this has for population persistence. Our research is focused on the Mediterranean streams and rivers of north-east Catalunya and the fish that inhabit them, in particular Mediterranean Barbel, Three-spined Stickleback, and Eastern Mosquitofish.

We are seeking a motivated field assistant to help set and run the field work during the summer of 2022. A full-time contract is offered, with a planned incorporation in June 2022 for a duration of 4 months. The salary offered is 1.410,73€ gross per month. The period can be extended to a 6-month contract at reduced hours if needed (with proportional salary). Local knowledge and experience with field work in the area, especially freshwaters, is a bonus.
