About Per Jonsson

Professor at the Department of Marine Sciences.

I am based at the Lovén Centre - Tjärnö situated 150 km north of Gothenburg and 130 km south of Oslo (see map).

My research interests include: biohydrodynamics, larval ecology, ecological & evolutionary effects of dispersal, chemical ecology, effects of biodiversity loss.

Research projects

What is a population? Linking dispersal to population divergence on seascape scale.

This project, funded by the Swedish Research Council (VR), will contribute to a better understanding of dispersal as a factor generating population structure with implications for local adaptation and demographic independence. Populations are demographically and genetically connected in space by dispersal. This connectivity has far-reaching consequences for population dynamics, community structure and genetic diversity. Dispersal is a fundamental process that affects population divergence with implications for evolutionary potential and conservation and management. However, the link between dispersal and divergence in demographic trajectories as well as in genetic differentiation is not well understood. This interdisciplinary project aims toward a new framework for modelling connectivity and population divergence on the landscape/seascape scale. We will formulate models of connectivity, based ocean flow, combined with population genetic models. Predictions of population divergence will be tested against observed data on demographic independence and genetic structure. Specifically, we address the following research problems:

1. Do models of present-day dispersal barriers predict observed demographic independence?

2. Do models of of present-day dispersal barriers predict observed genetic differentiation

The project will contribute to a better understanding of dispersal as a factor generating and eroding intraspecific biodiversity. Moreover, results are expected to support new strategies of conservation and management through identification of conservation units leading to better design of protected areas.

Larval dispersal and the design of marine reserve networks on Sweden

Creation of marine reserves or marine protected areas (MPA) is an important instrument for mitigation of biodiversity loss and the management of natural resources, e.g. threatened fish stocks. However, at present the effects of propagule dispersal and population connectivity for optimal MPA design are largely neglected. This may seriously compromise the sustainable protection of environmental values and natural resources that is the goal of MPA networks. This project, funded by Formas, features a multidisciplinary team of scientist and managers, including oceanographers, biological modelers, larval ecologists, spatial planners, managers of biodiversity and fish resources will address the critical component of how marine areas are connected through dispersal. The goal is to deliver tools to include dispersal, self seeding and connectivity into spatial planning and management and to facilitate the development of an efficient and sustainable network of marine reserves in the Baltic Sea-Kattegatt-Skagerrak area. This will be achieved by a combination of oceanographic and biological modeling producing dispersal probabilities. Necessary data on vertical behaviour for some target species will also be incorporated. In dialog with managers of biodiversity and fish resources we will build user-friendly tools designed to assess connectivity in spatial planning of marine reserves.
