Dr Jolle W Jolles
I am a von Humboldt Research Fellow at the Max Planck Department of Collective Behaviour and a Postdoctoral Fellow at the Zukunftskolleg, University of Konstanz. Fascinated by individual variability and how individual animals live and move together in groups, my research is focused on unravelling the role of individual heterogeneity in animal communities across social and ecological scales. During my PhD at the University of Cambridge (2016), I investigated how boldness and sociability variation was both affected by and drove the collective behaviour of schooling sticklebacks. Since then I started developing a unified mechanistic framework for understanding the role of individual differences in collective behaviour across social scales, combining the strong mechanistic approach of Collective Behaviour Research with fundamental concepts from Behavioural Ecology. More recently I started my own research group, the JollesLab, and build my own experimental fish lab. I am currently working on a number of exciting projects exploring the role of individual heterogeneity in groups of fish.
Hello everyone :) ! Like many other people, I really like animals. Therefore, after obtaining a bachelor’s degree in biology (“organisms biology, population, environment”) in France (yes, I’m French!), I took part in many volunteering projects during 6 months, in various safeguarding and reintroduction structures, such as a project in Thailand. Currently, I am a master student in Ethology, animal and human behaviour at the university of Rennes, France. I had the great opportunity to do my first-year internship with Jolle at the University of Konstanz. During my internship I did a mechanistic study of the boldness personality trait and its link to predation risk on three-spined sticklebacks. I had a great time here at Konstanz, I highly recommend it.
I am a Masters student in Biology with the focus on Ecology, Evolution and Behavior at the University of Constance. Before, I did an internship at the Marine Conservation Society Seychelles where I helped with the conservation and rehabilitation of freshwater turtles and sea turtles. The research project “Schooling in the dark” I am conducting in the JollesLab is part of my Master’s degree. Together with Jana, I will analyse the changes of schooling behaviour in sticklebacks under different light intensities, focusing on the dark. I am very happy to gain insights in the working atmosphere in the lab of Jolle Jolles and the Department of Collective Behaviour, and learn how to set up my own project, run experiments, and conduct analyses in R.
I am a Master student at the University of Konstanz. During my studies I discovered my fascination for animal behaviour and ecology and developed a particular interest in animal cognition and learning. Therefore, I conducted my Bachelor’s thesis in the Department of Collective Behaviour at the Max Plank Institute for Ornithology looking at group composition and collective problem solving in Zebra Finches. As a part of a master course I decided to do a project with Felicitas under the supervision of Jolle Jolles. Our project is focused on the schooling behaviour of sticklebacks at different light conditions, wondering how they can cope with no visible light available. It is very exciting to work with novel technologies to film and track the fish schools in the dark.
My research interests are behavioural ecology, social interactions, cultural behaviour, and cognition. After my BSc I worked as a field assistant for one year at the Kalahari Meerkat Project in South Africa and conducted my own independent analysis project on meerkat behaviour. I then did a MSc on cognitive biology at the University of Vienna under the supervision of Prof. Thomas Bugnyar. I designed and conducted several observational and experimental studies to investigate social behaviour and cognitive abilities of common ravens. I am doing a research internship in Jolle’s group studying predator-prey interactions and the role of phenotypic variation on individual survival in three-spined sticklebacks.
During the first semester of my Masters, I did a research project as part of the Fish Ecology advanced course supervised by Jolle Jolles and Jasminca Behrmann-Godel. I was interested in the role of individual behavioural types of three-spined stickleback and their effects on individual learning capabilities. Together with another masters student I set-up an experiment with 60 sticklebacks that we tested on some classic personality assays and association and reversal learning tasks. It was a great experience for me and I learned important new methods that are important to run a solid and controlled behavioural experiment.
Lauren de Wit
Hi everyone! My name is Lauren and I am a master student fascinated by animal behaviour. The last six months I had the pleasure of working with Jolle and his three-spined sticklebacks at the University of Konstanz. I studied the effects of individual behavioural tendencies on group learning performance. Different group compositions were tested in a Y-maze to study group learning and reversal learning. I have learned a lot about individual tendencies and group dynamics by observing stickleback behaviour both during experiments and in their housing tanks.
Marc Oliver Ley
In my Bachelor’s thesis, we looked at the influences on the predator-prey relationship between Pike and sticklebacks, caused by Schistocephalus solidus, a behaviour altering parasite. I conducted a range of experiments in the lab and investigated how the parasite altered the surival of individual sticklebacks. I found that that the parasite changes the infected sticklebacks behaviour considerably towards a piscivorous predator like the pike. Over the year I had a great experience learning how to run and analyse my own lab experiments.
