Abstract

The social environment plays a key role in resource acquisition across a wide range of species. Using the Trinidadian guppy as model system, we study how social tendencies and social environment affect resource detection and acquisition. The facultatively social nature of the guppy, combined with their dynamic natural environment, allowed us to effectively conduct a series of (social) environment manipulations in the wild. During this talk, I will discuss the most important outcomes of these field experiments: (1) Individuals consistently differ in foraging success across environments, (2) more social individuals do better, (3) females have a facilitating effect on male foraging success, and (4) an increase in same-sex conspecific number increases foraging success (up to a point) for both males and females. Our findings demonstrate causal relationships between conspecific number, social composition, and individual foraging success in the wild.

Bio

Lysanne Snijders is an assistant professor at the Behavioural Ecology Group of Wageningen University & Research (the Netherlands). She finished her PhD, with distinction, at the same group, studying the role of personality in territorial great tit networks. Next, she worked as a postdoc-fellow at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB, Germany) studying social foraging in wild guppies and as a postdoc-fellow at the Leibniz-Institute for Zoo and Wildlife Research (IZW, Germany) studying personality and migration strategies in tree-roosting bats. Besides fundamental insights in behavioural ecology she is also very interested in the practical applications of behavioural ecology to wildlife conservation. In 2020, Lysanne was awarded the Tinbergen Prize by the Ethologische Gesellschaft.
