Ecological research studies the distribution and abundance of species in time and space, and the interactions among organisms and with their environment. The ecological research at the department has a broad scope both in the choice of study organisms, from microorganisms to mammals and trees, as in the type of questions posed. Roughly, ecological research can be subdivided into several organisational levels; populations, communities and ecosystems.
An important research area within the population ecology research at the department is species interactions; as between plants and insects as well as between fish and their prey. The research focus both on the mechanisms affecting the strength of species interactions, from resource location by herbivores and predators to prey (plant or animal) defense, and the consequences for species distributions and evolution. Research within population ecology also involves conservation of threatened species, why species are threatened and what management actions may reduce threats.
The study of species interations involves both pair-wise interaction, entire food webs, how these are affected by the surrounding environment, and ecosystems. Ecosystems and their inhabitants are affected by both natural and anthropogenous processes; climate, eutrophication, pollutants, fragmentation and harvesting. A large number of project studying these effect, beside the ones listed below, are described under climate effects, environment and the sea.
