How do we protect genetic diversity if species, as currently circumscribed, contain multiple distinct evolutionary lineages, so-called cryptic species?
Sphaerodoridae is a group of marine worms characterised by the presence of spherical tubercles over their surface. They are scarcely known, probably due to their small size and low abundance. The relationships with other polychaetes, the systematics and classification of the group and their natural history are topics that require further investigations.
Sea slugs, or nudibranchs, had not been studied at all in Norway the past 60 years, until our project was initialised in 1997. We have been studying diversity of species and their distribution in Norwegian waters.
Understanding urban sociospatial organisation and demographic crises in a long time perspective by use of DNA analysis of human osteological material from medieval Trondheim, Norway.
Current tree-lines in Norway are heavily depressed by land uses associated with traditional (agri-) cultural practices, but reduced intensity of land use and a warmer climate can interact to cause an advance of the tree-line.
Comparative perspectives on the dynamics of early human approaches to the seascapes of Tierra del Fuego and Norway.
Molecular phylogeny, taxonomy, and historical biogeography of Lamiaceae subfamily Lamioideae, including surveys of alloploid speciation in two temperate Eurasian genera, Galeopsis and Lamium
The principal purpose of the present study has been to elucidate evolutionary relationships within subfamily Lamioideae using various molecular tools. The project is based mainly on herbarium specimens.
The Norwegian Sea holds a diverse fauna of polychaete worms, more diverse than previously anticipated. Recent work has discovered several new species and species described in the old literature but not seen since their description, has been rediscovered. Material from new samples will be targeted to discover the true diversity of polychaetes in the Norwegian Sea.
SPARC focuses on perennial alpine snow patches as long-term hunting environments. In certain regions, PSPs have been shown to contain important prehistoric artefacts, ecofacts and sites. The low-temperature conditions associated with these sites make for excellent preservation allowing organic remains to survive within the ice, sometimes for thousands of years. Many alpine snow patches are now melting away and important cultural and climatic specimens and information are being subjected to exposure and deterioration.
Forests provide a range of goods and services of vital importance for human society. The large increase in forest ungulate populations, notably moose (Alces alces) and red deer (Cervus elaphus) in Norway, over the last decades has been a key driver for changes in forest socio-ecosystems, particularly in concert with the changing climate.
The brown trout Salmo trutta is a dominant component of both the anadromous and stationary fish fauna in Norwegian watercourses, and of great cultural and socioeconomic importance for subsistence and recreational angling.
The main aim of this project is to contribute to the development of an urban archaeology of practice as an alternative to the processual research tradition within urban archaeology. This practice focuses on identification, documentation, and analysis of material remains in urban archaeological levels and other relevant sources in order to provide insight, to understand contexts, and to assess the long-term consequences of the formation of social practices in historical urban communities. The current challenge for the urban archaeology of practice is to establish a theoretically consistent and sustainable methodological basis for conducting empirical studies of urban material remains.
