Personality in Community Ecology Responses: Integrating the behaviour and species interactions of a marine invader
This project used a unique and innovative combination of experimental and theoretical research, to analyse the role of behaviour and individual trait variation in biological invasions. Invasive species are a current risk to global biodiversity, particularly in marine systems where shipping has produced a massive influx of introduced species. Invasive species have enormous economic and ecological impacts on the communities that they invade, which demands a greater understanding of the processes driving invasions and invasive-species. The overarching goal of this project way to disentangle the links between an animal’s behavioural traits and their interactions with other species. The experimental work aimed to analyse the invasive impacts of the round goby (Neogobius melanostomus) on aquatic communities in the Baltic Sea. By focusing on the round goby, a highly successful and damaging invader, this work provides important new data on the impacts of invasive species in northern Europe, as we as providing critical advances in our understanding of how individual traits influence the invasion process. The three research-specific objectives are: 1. To quantify links between individual personality types of animals and their food-web interactions. 2. To concurrently assess variability in the behavioral trait composition and food-web interactions of round goby populations, across their invasion front. 3. To systematically analyze the evidence that individual trait variability (particularly behavioural variability), alters species interactions and community dynamics.

Project objective
Consistent behavioural variation between individuals of the same species (i.e. animal personality) is very common in animals, from mammals to fish and insects. Personality types like boldness/shyness can change how the individual interacts with its environment, e.g. the outcome of predator-prey interactions. However, the effects of widespread personality variability on ecosystems is relatively unexplored. Recent work shows that personality variability can alter the nature of trophic interactions between species and potentially contribute to ecosystem stability. Therefore, PinCER will investigate animal personality as a functional trait, quantifying links between personality (e.g. boldness, exploration etc.) and diet, trophic position and body condition in individual animals. By quantifying the degree that personality variability translates to functional diversity in food webs, PinCER will provide unprecedented insights into the effects of personality on ecosystems. Building on the experimental work, a review paper will also investigate existing empirical literature on behavioural variability’s role in species interactions.Experimental work will focus on the round goby (Neogobius melanostomus), analysing the links between personality and trophic interactions across an ecological invasion gradient. The round goby is an invasive fish in the Baltic Sea and European inlet waters and a proven study subject for behavioural research. Results will also have management implications, giving highly focused individual data on the species’ impacts on Baltic Sea communities. A full-time secondment in the Baltic Marine Environment Protection Commission (Helsinki Commission) will focus on invasive species policy (management of ship-mediated introductions of non-indigenous species, e.g. the round goby) enhancing my training and career prospects. As such, PinCER will advance behavioural and community ecology, meet my skill acquisition needs and produce data for ecosystem management.
