3. INTERACTIONS

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”

5. 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.

6. 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.

8. From Soil to Ocean: Transfer of terrigenous organic carbon from permafrost soils to the Arctic Ocean

In order to estimate the effect of rising global temperatures on organic carbon (OC) stocks in the temperature-sensitivity Arctic environment, our project aims at investigating the transfer of terrestrial OC from permafrost soils to the Arctic Ocean. Detailed compositional analyses of bulk soil and sediments along a transport trajectory combined with compound-specific isotopic (13C and 14C) analysis of selected lipid biomarkers will be used to study alteration processes of organic matter occurring in the soil and its during transport. Sub-goals include to a) identify suitable biomarkers for soil organic carbon in permafrost soils, b) determine residence times of selected biomarkers in permafrost soils, fluvial and marine sediments, and c) quantify carbon transfer from source (soil) to sink (marine sediment) and its timescale.

9. 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.

10. Investigation of the physiological and cellular adaptation of plants to the arctic environ-ment – comparison with high alpine conditions

The objective of our work with arctic terrestrial plants and with algae is to study the range of climate adaptation as is expressed in special ultrastructure of cells and tissues, in photosynthetic metabolism, in antioxidative and sun screen compounds under a cold and reduced PAR / UV-B environment (climate different to alpine conditions). This is a comparison of ecophysiological processes already worked out mainly from high alpine plants, which live periodically under stronger cold and under different light regimes, especially higher UV-B and PAR irradiation. We want to find out, whether adaptations found in some alpine organisms occur similarly in polar forms.

11. Biology of Arctic macroalgae

The effects of stratospheric ozone depletion and of global warming on the marine biosphere are still underexplored, especially in the Arctic. Seaweeds are very important primary producers but are strongly susceptible to enhanced UV radiation and elevated temperatures, especially their spores. The UV susceptibility of spores has previously been invoked to determine the depth distribution of seaweeds. Therefore, we will investigate the effect of different radiation and temperature conditions on the ultra-structure, physiology and biochemistry of spores from various brown and green algae growing in different water depths. Moreover, we will study competition between zoospores of various species of brown macroalgae in order to get an insight about biotic factors structuring seaweed communities and also to explain more clearly the present seaweed zonation pattern.

12. IOANA

The project IOANA proposes to better understand the intimate coupling between ozone mixing ratios and particulate nitrate isotopic characteristics. Ozone Depletion Events which occur in Arctic coastal locations shortly after sunrise are a subject of interest per se (scientifically challenging for two decades) but also provide a context in which ozone mixing ratios are highly variable, enabling to characterize the dynamic of correlation and process studies with a resolution of a day. This is a first step towards the use of the isotope tool in reconstructions of the oxidative capacity of the atmosphere. This programme is a preparation of the IPY-OASIS project and propose to coodinate a set of collaborations than will be effective duing the International Polar Year.

13. ATMospheric Fluxes from Arctic Snow Surfaces - ATMS

The central objectives of the proposed ATMAS project are:  to quantify the photo-chemically triggered NOx and HONO re-emission fluxes from permanently and seasonally snow-covered surfaces in the Arctic near Ny-Ålesund,  to quantify the sources of NO3 in these snow-covered surfaces. In detail, the following scientific objectives of ATMAS can be distinguished: 1. to quantify atmospheric gradient fluxes of HNO3, HONO, particulate nitrogen compounds, and nitrogen in precipitation (snow and rain) above snow surfaces; 2. to quantify the emission of NOx and HONO from the snow pack as atmospheric gradient fluxes 3. to formulate an influx-outflow relationship that can be used in dependence on the snow type for (photo-)chemical atmospheric process models. The results of this research may be expanded to a regional (European) or global scale, to suggest how the NOx and HONO re-emission process and its consequences can be included into regional emission, dispersion and deposition models used in Europe.

15. ARCTAPHID: biology and ecology of aphid populations in arctic environment.

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

16. Study of the ice phase in Arctic mixed-phase clouds and its influence on the cloud-radiation interaction (EPOPEE) within the international atmospheric research project ASTAR (Arctic Study of Tropospheric Aerosol and Radiation)

The project EPOPEE is embedded in the international project ASTAR to study direct and indirect climate effects of aerosols and clouds in the Arctic. The particular goals of the project EPOPEE are to experimentally characterize the ice phase in Arctic clouds (including the ice phase) in situ, to study the aerosol-cloud as well as cloud-radiation interactions, and to develop adequate methods to validate remote sensing cloud parameters. In 2004 the project EPOPEE is mainly organized around in situ observations of detailed microphysical and optical cloud properties onboard the Polar-2 aircraft during the transition from polluted Arctic haze (observed especially in late winter, early spring months) to clean summer aerosol conditions. The transition from Arctic haze to clean summer conditions is quite sharp (a large amount of aerosols coming from Eurasian industrial areas accumulate over the Arctic and cover the Arctic by a layer of a smog-like haze of the size of the continent of Africa) due to a radical change in atmospheric transport patterns and is, thus, easy to identify. During Arctic summer, the high latitudes are then more or less “protected” from long-range transport of air masses from lower latitudes. The principal scientific objective of the project EPOPEE in 2004 will focus on studying the aerosol-cloud interactions with particular attention given to the ice phase nucleation in Arctic mixed-phase clouds. The interpretation of the instrumental observations will broadly benefit from a very close cooperation with the LaMP modelling group for theoretically coupling small-scale processes (cloud particle nucleation) with meso-scale dynamics. Furthermore, the project will focus on cloud-radiation interaction and the development of adequate methods to validate cloud parameters retrieved from remote sensing techniques. Therein, we will experimentally answer the question of how the different ice crystal shapes govern the scattering phase function of respective crystals. Moreover, the in situ cloud measurements will allow to develop an adequate strategy for the interpretation of remote sensing data from a depolarisation Lidar onboard the same aircraft (Polar-2).

17. The Effect of solar UV on lipids in the planktonic food chain of polar freshwater ponds

Plankton of shallow polar freshwater water bodies is exposed to increasing levels of ultraviolet radiation (UVR) due to the limited water depth. Daphnia (Crustacea, waterflea) and algae are common representatives of the food chain in these water bodies. Daphnia almost exclusively use lipids for energy storage, which they obtain from their food (mainly algae). Therefore, Daphnia and algae are closely linked to each other. Preliminary experiments on the UV-induced damage in phyto- and zooplankton point to lipids as one of the key players. With this application we want to identify how algae specific lipids and fatty acids (FA) are modified by UVR. The factors modifying UV-doses to the animals and their food are depth of the waterbody and DOC (absorbs UV). A pondsurvey shall provide a wide spectrum on ponds which vary in DOC and depth. Lipid analysis of Daphnia and their food of these ponds as well as physical parameters of the pond waters shall identify correlations between UV-exposure and specific fatty acids. This shall enable us to estimate the effect of solar UVR on the freshwater plankton community in polar ponds.
