Influences of forests on invertebrate communities in Icelandic streams
Effects of forests on headwater stream invertebrate communities were studied in eastern and southern Iceland, which are two geologically different regions. The eastern research area is composed of solid basaltic rock with direct run-off streams. The streams drain treeless, birch and conifer …

Biological diversity in Icelandic groundwater fissures
Iceland has an abundance of fissures that are parallel to the Mid-Atlantic ridge where bedrock cracks as a result of continental rifting. In some areas fissures penetrate the aquifer and expose the groundwater within the bedrock. The main objective of the study was to measure the biological …

Effects of prey distribution on resource defense, foraging behavior, and growth in stream-dwelling Arctic char (Salvelinus alpinus)
Animals exhibit variable competitive strategies in response to the distribution of critical resources, ranging from indirect interactions during resource depletion (i.e., exploitative competition) to direct attacks and monopolization (i.e., interference competition). Spatial distribution of …

Biological diversity of epibenthic invertebrates in relation to environmental factors in lava caves around Lake Mývatn (N-E Iceland)
Biodiversity, and its understanding and maintenance, are nowadays concerns in many fields of sciences. In freshwater, epibenthic invertebrates are important for their environment as consumers at intermediate trophic level and as food resources for other organisms. Their sensitivity to environmental …
