The terrestrial environment of the High Arctic consists of a mosaic of habitat types. In addition to the natural habitat diversity, various human-influenced types may occur. For the resident invertebrate fauna, these anthropogenic habitats may be eit

Enchytraeids as indicator of soil quality in temporary organic grass-clover leys under contrasting management: A feasibility study

Autor: Jørgen Eriksen, Kristine Maraldo, Rüdiger M. Schmelz, Thomas Larsen, Bent T. Christensen

Publikováno v: Maraldo, K, Schmelz, R, Larsen, T, Christensen, B T & Eriksen, J 2015, ' Enchytraeids as indicator of soil quality in temporary organic grass-clover leys under contrasting management : A feasibility study ', Soil Biology & Biochemistry, vol. 91, pp. 32-39 . https://doi.org/10.1016/j.soilbio.2015.08.023

One objective in organic farming is to sustain the quality of the soil resource. Because enchytraeids are an important soil faunal component, they stand as bioindicators of soil quality. We tested this candidature in a field experiment on loamy sand

Many aspects of the feeding ecology of terrestrial oligochaetes are poorly understood despite the essential role of these soil and detritus feeders for maintaining soil fertility. To investigate dietary contributions of various soil components to two

Supplementation of nutrients by symbionts enables consumers to thrive on resources that might otherwise be insufficient to meet nutritional demands. Such nutritional subsidies by intracellular symbionts has been well studied; however, supplementation

Forty six species of invertebrate were collected from the manure enriched imported soils below the abandoned cow sheds in the Russian mining town of Barentsburg, Svalbard. Of these, 11 (24 %) were new records for Svalbard, including Collembola, gamas

Studies of biological responses in the terrestrial environment to rapid changes in climate have mostly been concerned with above-ground biota, whereas less is known of belowground organisms. The present study focuses on enchytraeids (Oligochaeta) of
