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:

  1. Monitor predation pressure using artificial nests
  2. Monitor real predation pressure on Calidris nests using Tiny Tags
  3. Observations of predators and lemmings (3b: fox scats DNA barcoding)
  4. Assessing lemming (or “rodent”) relative abundance using different methods
  5. Assessing “herbivores” (excl. rodents) relative abundance using “faeces transects”

3. LAPBIAT-Lapland Atmosphere-Biosphere facility

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.

4. National Inventory of Landscapes in Sweden (NILS)

NILS is a nation-wide environmental protection programme that monitors the conditions and changes in the Swedish landscape.

The programme started in 2003 and includes field inventory and aerial photo interpretation of permanent sample plots in all types of terrestrial environments.

NILS is mainly funded by the Swedish Environmental Protection Agency and an important objective is to provide information for follow-up of the Swedish national environmental objectives and the Natura 2000 network. NILS also contributes data to environmental research and international reporting.

5. Arctic and Alpine Stream Ecosystem Research

The project, Arctic and Alpine Stream Ecosystem Research (AASER), started within EU’s Climate & Environment Programme and now continues with national funding, primarily Norway, Italy and Austria. The objective is to study dynamics and processes in rivers systems in Arctic and Alpine regions. Emphasis is given to the relationships between benthic invertebrates and environmental variables, especially in glacier-fed systems and in relation to climate change scenarios. On Svalbard research is concentrated around Ny Ålesund, particularly Bayelva and Londonelva. In 2004 the focus will be on the use to stable isotopes to detect transfer processes within and between ecosystems.

6. Haliclona natural products

In contrast to many other marine regions, chemical interactions between organisms in Arctic waters are little understood. This project investigates natural products and chemical interactions in the sponge genus Haliclona in temperate and polar waters. Several new secondary metabolites isolated from Haliclona show feeding deterrence and activity against bacteria and fungi, but the compound composition varies with habitat and year. That raises the question whether sponges of the genus Haliclona as a model are able to adapt to changing environmental factors such as water temperature and colonization by bacteria by varying their secondary metabolite composition.

7. Behavioral and evolutionary implications of strict monogamy. An experimental approach in panarctic seagull: the black-legged kittiwake Rissa tridactyla breeding in Alaska

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.

8. Long distance pollen transport in the Arctic: 1. Greenland

The submitted proposal aims to perform the monitoring of the pollen rain in the Greenland atmosphere by distinguishing the local pollen production, relatively low, from pollen grains originating from other Arctic areas. A regular monitoring of the atmospheric pollen content must be performed in order to evaluate the amount emitted and characterise the seasonality of the emission. A comparison with air mass trajectories must allow the modelling of long distance transport

9. Living in a spatially structured environment: evolutionary ecology of seabird-parasite interactions

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).

11. Relative importance of different sources of particulate matter in the Kongsfjorden environment

The general objective of this research concerns the quantitative and qualitative study of particulate matter retained in natural (sea-ice and sediment) and artificial (sediment traps) traps in order to determine the main origin (autochtonous and allochtonous) and the relative importance of different fractions of particulate matter and to follow their fate in the environment. To quantify the autochtonous origin of particulate matter, primary production, nutrient uptake, biomass distribution, phytoplankton community structure and fluxes in the first levels of the trophic chain will be investigated. Studies will be conducted in the sea-ice environment and in the water column and compared to the particle fluxes measured both in the water, using sediment traps and in the sediment, by radiometric chronology, in order to estimate the different contribution of these habitats to carbon export to the bottom. The zooplankton will be identified and counted and primary production, nutrient uptake and phytoplankton dynamics will be related to hydrological structure and nutrient availability in the environment. The Kongsfjord results particularly suitable for the main objective of this research as it is influenced by important inputs of both atmospheric (eolic and meteroric) and glacial origin and is characterised by a complex hydrological situation which may promote autochtonous productive processes, thus determining important particulate fluxes.

13. Climate Change and Competitive Interactions

The effects of climate change in a dynamic competitive interaction between two or more species can be bought about either as direct responses of species to change or indirectly through effects on competing species. Intertidal barnacles are ideal model organisms to test these alternative causal mechanisms, being easily censussed and directly competing for space. Single- and multi- species models will be developed for barnacles in SW England to determine whether direct or indirect mechanisms better predict responses to change. The models will include functions for space-limitation, environmental influence and, in the latter models, functions for interspecific competition. Historical data from a network of sites collected over a 40-year period will be used to develop and test the models.

14. Environmental sensitivity of cold water corals

Distribution • What is the current distribution of coral colonies in the North Sea? • Where are coral colonies located on the structures? • Do any colonies show evidence of exposure to drill cuttings? Monitoring & Environmental Recording • What hydrodynamic regime and levels of suspended particulate material are coral colonies exposed to? • Does the coral skeleton retain an archive of any past contamination? • Does skeletal growth vary over time and does this correlate with any past contamination? • How variable is the rate of coral growth and does this correlate with any environmental variables? Environmental Sensitivity • What effect does increased sediment load have on coral behaviour and physiology? • What effect does exposure to discharges (e.g. cuttings and produced water) have on coral behaviour and physiology? • Are such exposures realistic in the field?

15. Bacterial diversity in marine sponges

The aim is to study the diversity and function of marine bacteria closely associated with marine sponges. The special character of life strategy of the community (symbiosis – commensalism), with special emphasis to the identity and the recruitment of bacteria during live cycle of the sponges will be described.

16. Bacterial populations in the pelagic foodweb

Since nearly all microalgae are associated with bacteria and some harbor intracellular bacteria, it is most likely that these bacteria are involved in the development or termination of natural occurring plankton assemblages. The diversity and development of associated bacteria in microalgae cultures and during phytoplankton succession will be described by molecular analysis of the bacterial community structure and by phylogenetic analysis of involved microorganisms.

17. Bacterial diversity in echinodermata

Little is known about the consistency or phylogenetic affiliation of accociated intra- or extracellular bacterial populations in Echinodermata. Because certain taxa harbour bacteria and other not, these associations are presumably originated by coevolution and not by ecological circumstances. The intestine of echinodermata is populated by huge amounts of bacteria. Due to the different feeding strategy of echinoderms it is controversly discussed whether these bacteria are passively taken up or if they are permanently present. Hence it will be possible to elucidate if vertical transmission occurs or bacteria are recruted. With the knowledge of phylogenetic affiliations of microbial symbionts and their distribution (or localization) in different hosts, the physiological/biochemical status of the association will be investigated. The main emphasis will be the characterization of the in situ situation by adequate histological techniques (crysectioning) and “passive” (FT-IR) or “active” chemical imaging (confocal imaging, using fluorescent enzyme substrates or physiological dyes). The main experimental work in this WP bases on the creation of 16S-rDNA sequence libraries of echinoderrm associated bacteria (SCB & intestinal). Signature sequences will be analyzed and specific gene probes will be designed and applied.

HIMOM will aim to provide a system of methods, the so-called Hierarchical Monitoring Methods (or HMM), to determine system status and changes which are expressed by biological and physical variations within inter-tidal areas. The HMM will aim to provide a management strategy tailored to the needs of End User involved in activities relating to the sustainable development of tidal flat areas around Europe. The HMM system will represent a hierarchical suite of activities, ranging from simple ground measurements of biota and physical characteristics to remote sensing of spectral reflectance properties for the analysis of basin scale systems.

20. Ecological and Physiological Investigations about the Impact of UV Radiation (UVR) on the Succession of Benthic Primary Producers in Antarctica

The succession of macro- and microalgal communities in the Antarctic will be investigated in field experiments under various UV radiation (UVR) conditions and in the absence or presence of grazers. The observed differences in the succession process will be correlated to physiological traits of single species, especially in spores and germlings, which are the most vulnerable stages in their life histories. Photosynthetic activity of the different developmental stages will be measured routinely. Additionally we plan the determination of pigment composition, C:N ratios, content of UV protective pigments and of possible DNA damage. The experiments will start in spring, concomitant to the time of highest UVBR, due to the seasonal depletion of the ozone layer in the Antarctic region. Supplemental laboratory experiments will be conducted to determine the effects of UVR on spores and germlings of individual species. In addition to the above analyses, we plan to examine of UVR induced damage of cell fine structure and of the cytoskeleton. The results of both the field and laboratory experiments will allow us to predict the consequences of enhanced UVR for the diversity and stability of the algal community.
