From terrestrial greening to coastal darkening
Is it possible that a warmer taiga in Russia, Swedish urbanisation policy, or tree planting in Eastern Europe can influence the timing of phyoplankton blooms or fish spawning? through the RCN project A green-blue link made browner: how terrestrial climate change affects marine ecology (2019-), we will spend the next few years investigating a series of ecological links that might explain such curious connections.
Trait-based Marine Ecosystem Models
Traditionally, ecosystem models represent a few important groups of organisms. In trait-based models organisms are characterised as continuums of traits, and winners emerge from a process resembling natural selection.
Animal Decision Making
We study how to model the processes of and architectures for decision-making. We have focussed on cognitive mechanisms but also studied hormonal control of the organism. While understanding animal behaviour is still our goal in most cases, it has also led to interest in animal wellbeing.
Evolution of Mating Systems
How may mating strategies affect parental investment and cooperation? Using theoretical models of common ecological mechanisms we study how extra-pair mating may trigger male-male cooperation in predator defence and sharing of resources. This provides an adaptive explanation for female promiscuity and a new hypothesis for the evolution of cooperation.
Evolution in Fisheries Science
Industrial fishing is the main source of mortality for many commercially harvested fish stocks, and there is increasing concern that this will cause evolutionary changes in the fish species themselves. We use models as a virtual laboratory to study fish evolution. By varying the external pressures, such as fishing, we simulate fish evolution to assess ecological and economical consequences.
Models of Early Life Stages in Fish
Larval fish ecology is a theme connecting oceanography and plankton ecology to fisheries science. We build models of larval feeding, bioenergetics and behaviour to understand how the environment affect their growth and survival. This is the key to understand why fish spawn where and when they do, and how environmental change may influence recruitment and phenology.
