The position is a 14 month post-doc, working in the lab of Emily Burdfield-Steel, and in collaboration with Johanna Mappes at the University of Helsinki. The role will involve working in Finland, at Lammi research station for part of the year (in winter) in order to carry out experiments with wild-caught great tits. The aim is to test for the presence of the decoy effect when birds are evaluating chemically-defended prey – and therefore if predator perception of prey value is context dependent. This project combines classic foraging research with frameworks from marketing theory to understand how the ecological context influences predator behavior, and subsequently selection on chemically-defended prey.

You will work with wild-caught great tits, foraging on artificial prey, to understand both how they weight prey size and distastefulness, as well as how the available options shape their choices. You will conduct learning and preference trials, help to design the experimental procedure, and analyse and write up the findings for academic publications. You will also be part of the Institute of Biodiversity and Ecosystem Dynamics and attend group meetings and seminars.
Tasks and responsibilities:
Your experience and profile:
We offer a temporary employment contract for 38 hours per week for a period of 14 months. The preferred starting date is as soon as possible. For this position the University Job Classification profile Researcher level 4 applies.
The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 3,546 to € 5,538 (scale 10). In addition, you will receive a 8% holiday allowance and 8.3% year-end allowance.
A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants.
The Collective Labour Agreement of Universities of the Netherlands is applicable.
Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:

Where you will work
The Institute for Biodiversity and Ecosystem Dynamics (IBED) is one of eight research institutes of the Faculty of Science at the University of Amsterdam. The research at IBED aims to unravel how ecosystems function in all their complexity, and how they change due to natural processes and human activities. At its core lies an integrated systems approach to study biodiversity, ecosystems and the environment. IBED adopts this systems approach to ecosystems, addressing abiotic (soil and water quality) and biotic factors (ecology and evolution of plants, animals, and microorganisms), and the interplay between those. The IBED vision includes research encompassing experimental and theoretical approaches at a wide variety of temporal and spatial scales, i.e. from molecules and microorganisms to patterns and processes occurring at the global scale. The University of Amsterdam has excellent high performance computing facilities. Furthermore, IBED has a dedicated computational support team with specialized knowledge of bioinformatics, (geo)database management and scientific programming. IBED also works with non-academic partners to deliver transdisciplinary science for society.
The position will be based in the Department of Evolutionary and Population Biology. Evolutionary and Population Biology Research in the department of Evolutionary and Population Biology focuses on understanding the ecological and evolutionary processes that drive community dynamics and speciation, and determine biodiversity patterns.
