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.

Important progress has been made in recent decades to describe and understand how arctic terrestrial vertebrate interact, especially concerning predator-prey interactions. Indirect interactions between different prey species modulated by shared predators (e.g. Arctic fox) are believed to have important impacts on the structure and/or dynamics of some communities. Yet, our understanding of these types of interactions is still fragmentary. To fill that gap, we will build on ongoing projects exploring related questions in Canada (Marie-Andrée Giroux, Nicolas Lecomte, Joël Bêty) and Greenland (Olivier Gilg, Niels M. Schmidt), while taking advantage of existing networks (ADSN in North America and “Interactions” program in Greenland and Eurasia). The aim of the project is to promote the implementation of several common protocols that will (1) improve each collaborator’s knowledge at the site level and, more importantly, that will (2) be merged across sites and years to improve our understanding of the functioning and the influence of indirect interactions on arctic vertebrate communities in general.
Five types of data have been identified (by the 5 initiators of the project already mentioned above) as being mandatories to answer questions related to this topic. These data sets will be collected using 5 specific protocols described in the following chapters:
FUVIRC will serve ecosystem research, human health research and atmospheric chemistry research by providing UV monitoring data and guidance (i.e. calibration of instruments, maintenance of field test sites), research facilities (laboratories and accommodation), instruments and equipment.
The main objective of the facility is to enhance the international scientific co-operation at the seven Finnish research stations and to offer a very attractive and unique place for multidisciplinary environmental and atmospheric research in the most arctic region of the European Union. Factors such as, arctic-subarctic and alpine-subalpine environment, northern populations, arctic winters with snow, changes in the Earth's electromagnetic environment due to external disturbances and exceptionally long series of observations of many ecological and atmospheric variables should interest new users.
The activity in 2004 will be devoted to two projects: First, we will perform banding of breeding adult Kittiwakes in the Kongsfjord area. The Kittiwakes will in addition to standard metal rings be equipped with a colour-ring with a combination of letters and numbers, making identification at a distance easier. This banding programme was initiated in 2003 and will in the coming years be used to calculate local survival rates of the Kittiwakes breeding the Kongsfjord area. Secondly, we intend to place a number of breeding boxes for Snow Buntings in the Ny-Ålesund area. In the coming years this will make access to breeding adults and nestlings easier enabling physiological studies. These studies will focus on various aspects of metabolism and energetics of the breeding population of Snow Bunting on Svalbard, and we also want to compare the physiology of the Svalbard population with the breeding populations on ’mainland’ Norway.
In a context of global change, arctic ecosystems are exposed to deep modifications not only of the biology and ecology of endemic species but also of the interactions they may have with an increasing number of introduced species. This project attempts to assess in Svalbard, the impacts of global changes on aphids. These phytophagous insects are particularly relevant organisms for studies on the effects of global warming and biological invasion because 1) of their extreme sensitivity to micro- and macro- changes due to their spectacular rate of increase and phenotypic plasticity and 2) of their colonizing capacity conferred by their parthenogenetic mode of reproduction and their dispersal potential
This project's goal is to experimentally study strict monogamy in a panarctic seagull, the black-legged kittiwake, in Alaska. It studies mate choice (which is crucial because no mixed strategy is used) in relation to indivdual quality, fitness and sexual conflict in strictly monogamous species. It is rooted in a detailed knowledge of the species’ biology and the merging of three teams (French, Austiran and Alaskan) with long-term experience researching kittiwakes. It uses the unique experimental Alaskan setting for wild populations.
Fieldwork amongst Yakut horse breeders and the other inhabitants of the extreme east of Siberia, whose existence shows a link with horses, will facilitate an understanding of the unusual features of horse breeding in the Arctic regions. The comparison of the results with the existing sources will enable us to highlight the importance of the horse figure in the various cultural domains of the Sakha people and the similarities and differences that have developed since written records began, i.e. as of the mid 17th century.
The aim of this research program is to examine the response of animal populations to environmental variability at different spatial scales. We attempt to determine how individuals respond to the spatial heterogeneity of their environment, and what are the consequences of this response for the dynamics of subdivided populations. Specifically, we consider an ecological system involving biotic interactions at three levels: seabirds, their tick _Ixodes uriae_, and the microparasite _Borrelia burgdorferi_ sensu lato (Lyme disease agent). Colonies of seabirds represent discrete entities, within and among which parasites can circulate. Our previous work on this system in the norwegian arctic has enable us to show that (1) host dispersal can be affected by local conditions, (2) seabird tick populations are specialised among different host species, namely between sympatric kittiwakes _Rissa tridactyla_ and puffins _Fratercula arctica_, (3) in the kittiwake, females transmit antibodies against _Borrelia burgdorferi_ when their chicks have a high probability to be exposed to the tick vector. We propose to combine different approaches, incorporating field surveys and experiments and population genetic studies (of hosts and parasites), in order to better understand the role of local interactions and dispersal in the dynamics of such a system. The research program implies collaborations with researchers from other french groups, as well as with Canadian (Queen’s University) and Norwegian colleagues (from NINA and the University of Tromsø).
The objectives of this project is to study the effect of environmental stochasticity on the Svalbard reindeer population dynamics, nad further evaluate how this may affect reindeer-plant interactions.
