Phylogenetic relationships and processes of evolution are the main focus of my research and I’m going to work in the Pheromone group. There I will study the host-race formation in the browntail moth, Euproctis chrysorrhoea L. (Lepidoptera: Lymantriidae). I will assess if browntail moth populations feeding on different host trees across Europe are genetically differentiated and, if so, to what extent is this related to differences in the host trees.

I am interested in how environmental variation in space and time affects populations and food webs through the intra- and interspecific interactions between individuals, mediated by their plastic traits and flexible behaviours.

In particular, I investigate how in structured populations flexible movement behaviour and plastic life history traits interact with stage-specific ecological performance. To this purpose I use a range of laboratory and natural systems. Currently, I study (1) the causes and consequences of partial fish migration on lake ecosystems, (2) the size- and condition-dependent trade-offs between foraging, inter-habitat movement and predator avoidance behaviour in a Chaoborus-Daphnia-Algae community, and (3) how in soil mite metapopulations heterogeneity introduced by spatial variation in stage-specific mortality and complex life cycles jointly determine local and regional dynamics.

I am interested in how sexual behaviour influences the evolution of animal societies. Specifically my work focuses on two main questions: Why do individuals cooperate over producing offspring, given that they are predicted to be selfish and reproduce themselves? Why do some individuals choose to reproduce with particular partners and reject others? I address these questions using a combination of experimental and comparative analyses.

My main interest lies at the interface of ecology and physiology. I am specifically interested in how human-induced environmental stress, such as pollution and nutrition, influences the oxidative stress response and its consequences for individual performance and population dynamics in wild vertebrates.

My research interests are focused on the ecology, biology, and the population genetic structure of planktonic organisms. I am using genetic markers to study phytoplankton repartition in space and time, and compare genetic data to environmental factors in order to understand what shapes Läs mer »

Med ojämna mellanrum har jag tänkt presentera medarbetare inom Biologiska institutionen. Först ut är våra nya enhetschefer och nu har turen kommit till Staffan Bensch. Staffan är professor i zooekologi och leder den nya enheten MEMEG (vilket står för molekylär ekologi, mikrobiell ekologi och evolutionär genetik om jag har förstått det hela rätt). Läs mer »

I am a plant ecologist interested in various ecological and evolutionary questions from species interactions to management issues. My research focuses on modelling and understanding plant population dynamics (including invasive species) using quantitative methods. I am also interested in methods for small demographic data sets and statistical issues in general. I often combine experimental and theoretical approaches in my research.
