Study of ecosystem services from mires

Many of the functions of a mire is considered ecosystem services to man, e.g. its ability to store carbon and water. Especially its ability to store carbon has been given much focus in the last years’ climate debate.

The influence on physiology and environmental variables on the migration patterns and habitat use of brown trout

In coastal areas where Brown trout (Salmo trutta L.) have free access to the sea, some individuals remain as residents in the watercourse, while other conspecifics conduct periodical feeding migrations to the marine habitat. Whether an individual becomes resident or anadromous (often termed as sea trout) is affected both by genetic and environmental variables.

Ungulate-mediated effects on ecosystem functions and services in boreal production forests

To study some of the complicated interactions between large herbivores, vegetation, and climate, we compare field measurements made inside and outside large exclosure fences that have been erected on recent logging sites. By using long-term ecological data collected in several different forest types with known herbivore densities, we hope to be able to explain the observed differences in forest development.

Using herbarium specimens to elucidate the evolutionary genomics of plant invasion

In herbaria, a vast amount of plant species from different time periods and locations are preserved. Due to improvements in DNA extraction, sequencing and analysis, it is now possible to obtain genomes from historic herbarium samples.

Conservation genomics of red-listed plants prevalent in Central Norway

Species are used as a fundamental unit in biology, ecology, and conservation, meaning that their delimitation is essential. However, delimiting species is sometimes problematic, especially for recently formed or relatively young species with few or no discriminating features, cryptic species and taxa prone to parallel and convergent evolution.
