ENVINET Activities Catalog

ENVINET Activities Catalog

ENVINET (European network for arctic-alpine multidiciplanary environmental research) is a research infrastructure network focusing on multidisciplinary environmental research in Europe. The network involves representatives from 18 environmental research infrastructures from the European Alps to the Arctic, representatives of their users and representatives from relevant international organizations and networks. The participating infrastructures cover a broad range of environmental sciences primarily within atmospheric physics and chemistry as well as marine and terrestrial biology.

The ENVINET project directory covers data and observation activities at these stations.

Other catalogs through this service are AMAP, SAON and SEARCH, or refer to the full list of projects/activities.

1. Feeding biology of the cyclophoran Symbion pandora

Symbion pandora is a commensal on Norway lobster (Nephrops norvegicus) with a very complicated life cycle. The species was described very recently and appointed to a new phylum, Cycliophora. Obviously nothing is known about the biology of this animal. The present study investigated the feeding biology of Symbion pandora. This was investigated by offering them two different high quality food items: Algae and mussel. Additionally, incubations with radiolabelled dissolved amino acids were done to estimate the energy contribution from DOM. A specific goal was to quantify the amount of organic matter taken in during one meal and estimate how much this contributes to the total energy requirement of internal budding, production of larvae etc. during the life cycle of the cycliophoran. This was done by autoradiography and radiolabel incorporation.
