In order to determine the role of contaminants in declining populations of seaducks, it is proposed that: (1) archived samples of Oldsquaw collected from their Canadian arctic breeding grounds be analyzed for Hg, Se and Cu (in liver), Cd (in kidney), Pb (in wing bone), and selected samples be screened for a wider range of metals (in liver), and (2) archived samples of Oldsquaw wing bone be analyzed for stable isotopes (13C/12C; 15N/14N, and 34S/32S) and strontium (Sr) to discriminate whether birds from certain geographical areas of the Arctic are overwintering in freshwater (i.e. Great Lakes) or marine environments.
The possibility of restoring the salmon stocks in the Tuloma system is assessed by collecting background information on the river system: present fish fauna, habitat quality, migratory routes etc. Planning the restoration including technical and management aspects is under way.
Monitoring of the salmon stocksof the Teno and Näätämö river systems is based on long term data collection on juvenile salmon production, biological characteristics of the spawning stock, origin of salmon (wild/reared) and statistics on fishery and catches. Information on other fish species than salmon is also available.
The ZERO database contains all validated data from the Zackenberg Ecological Research Operations Basic Programmes (ClimateBasis, GeoBasis, BioBasis and MarinBasis). The purpose of the project is to run and update the database with new validated data after each succesfull field season. Data will be available for the public through the Zackenberg homepage linking to the NERI database. The yearly update is dependent on that each Basis programme delivers validated data in the proscribed format.

This study aims at reconstructing the Barents Sea marine ecosystem before the exploitation by man. This reconstruction will be made by using the existing archival resources on catch statistics from the 17th to 19th centuries in the Netherlands, Germany, Denmark and the United Kingdom, in combination with the present knowledge an animal behaviour and food web structure. Fieldwork is planned in two former hunting areas in Spitsbergen: the Smeerenburgfjord and the Storfjord to study both the structure of the recent marine ecosystem and the composition, size and dating of the recent bird rookeries. This information in combination with the historical data will be used to reconstruct the original ecosystem.
In order to manage populations of migratory geese a better understanding of the mechanisms that determine the size of these populations is needed. The objective of this project is to investigate such mechanisms, within the framework of the entire population of Dark-bellied Brent Geese, that winters in western Europe, and breeds in northern Siberia. The final objective of this project is to help predict future numbers of geese that will winter in western Europe in order to be able to forecast levels of agricultural damage caused by geese. Though hunting is an important factor determining the size of most goose populations, this is not a focal point in this project. Therefore this project focuses on a virtually non-hunted subspecies, viz. the Dark-bellied Brent Goose. Research activities Field work has been carried out in the Pyasina-delta in northern Taymyr, Russia during six consecutive summers from 1990 - 1995 in order to cover two complete lemming cycles. The project focuses the one hand on natural predators (like arctic foxes, Snowy Owls, Glaucous Gulls and Herring Gulls, and even Polar Bears) as a regulatory mechanism for the Dark-bellied Brent Geese, a virtually non-hunted subspecies. Lemming cycles have an important effect on the abundance and behaviour of most of these predators, and measuring lemming density forms an integral part of this study. On the other hand weather conditions, as well as the body condition of the geese themselves are being studied, because those factors are in themselves extremely important predictors of breeding success.
The ecology of the Greenland Right Whale is studied using the historical information from written sources from Dutch archives. The Spitsbergen and Davis Strait populations of the Greenland Right Whale were so heavily hunted that they are almost exterminated now in the northern waters. The whale bones on the beaches of Arctic islands are the archaeological evidences of this exhausting hunt. Very often whaling logbooks, crew statements and lists of catch figures are the only sources of information preserved of this animal in these regions. In this project recent biological information of the animal in the seas around Alaska and historical information of the whale in the North Atlantic and Davis Strait is used to reconstruct the migration, distribution and ecological behaviour of the Greenland Right Whale in the North Atlantic Ocean.
Large numbers of birds breed each summer on the tundra of the northern hemisphere. Two prominent groups in the Arctic bird fauna are waders and waterfowl (ducks, geese and swans). Breeding, which is an energetically costly activity (Drent & Daan 1980), is especially costly in the high Arctic. This is mainly due to low temperatures and high wind speeds in an open landscape (Piersma & Morrison 1994, Wiersma & Piersma 1994). In addition, the summer period is very short. This leaves little time for necessary pre-breeding, breeding and post-breeding activities. Thus, costs are high and available time is short. In order to reach their breeding grounds, arctic birds have to migrate over vast distances between their Arctic breeding sites and temperate or tropical wintering grounds. Migration is also an energetically costly event. This generally high rate of living puts high demands on the birds and we may expect the birds to have evolved a wide range of physiological and behavioural adaptations. Given the inaccessibility of most tundra areas and the necessity of relatively advanced techniques, ecological energetic studies of wader and waterfowl are relatively scarce (with the notable exception of tundra breeding Nearctic geese). With this project we aim at measuring and describing some important energy turnover processes of waders and waterfowl during the short and hectic Arctic summer and to evaluate them in an evolutionary context. We will pay particular attention to the importance of energy and nutrient stores with which the birds arrive at the breeding grounds for egg production, energy turnover of breeding birds in relation to species and microclimate, and the fat deposition and basal metabolism of birds preparing for autumn migration. The project is partly a continuation of work carried out during the Swedish-Russian Tundra Ecology Expedition 1994 (TE-94). Research activities: Capital vs. income breeders Since the favourable season is short for Arctic breeding birds, they are hard pressed to start egg laying immediately after arrival at the breeding grounds. However, upon arrival food availability is often low. It is thought that female birds planning to start a family on the tundra are forced to produce a clutch using, at least to some degree, body reserves accumulated prior to or during their migratory journey. Birds using such a strategy are called capital breeders, in contrast to income breeders' that only use resources obtained during the reproductive period (Drent & Daan 1980). We seek to investigate how commonly the capital breeder strategy is on the Nearctic tundra and how its use varies with: - Species: large species are expected to be more dependent on this - Strategy as their breeding seasons are longer and they are thus more time stressed. - Site: birds at sites where circumstances allow an early start of the breeding season may not be equally dependent on capital breeding than birds using late sites. - Timing: early arriving birds are more pressed to use the capital breeding strategy than late arriving birds, the latter being able to produce eggs from the food available upon arrival. The different potential food sources to birds often have distinct isotopic ratios of C12/C13 and N14/N15 depending on environment and metabolic characteristics. Isotopic ratios of C and N can therefore serve as a kind of fingerprint for these food stuffs. These specific ratios will ultimately also be reflected in the isotopic composition of the consumers tissues; especially with regard to C12/C13 ratios (Hobson & Clark 1992). Distinct differences may therefore also be expected in tissue isotope ratios of newly hatched young from capital and non-capital breeders. Such differences may also appear within nests in case the female has used a mixed strategy. Although in developing tissues these differences may rapidly fade away, isotope differences between young may be fixed in down feathers already present at hatching. Comparing the isotope ratios in down samples within broods with isotope ratios in potential food sources at the breeding ground thus provides a clue to the extend the mother made use of the capital breeding strategy. We will collect down, feathers and blood from all birds trapped. We will concentrate on waders, yet, also waterfowl are of high interest (although the chances to trap birds are smaller). Of highest priority will be down from chicks and blood from parent birds. In likely foraging areas of parents and chicks that we have sampled, we will collect insects and plants and other possible food sources. At the NIOO the samples will be analysed for C12/C13 and N14/N15 ratios using mass spectrometry. The fact that we will visit many different habitats with different climate, foraging conditions and phenology is a major prerequisite for successfully conducting this part of the project. Energy turnover of brooding birds The few available measurements of daily energy expenditure (DEE) of incubating waders in tundra regions, using the doubly labelled water (DLW) method, have shown that breeding in the High Arctic is indeed costly (Piersma & Morrison 1994, Piersma et al. unpublished data from Siberia). The high cost stems from the combined effects of low temperatures and high wind speeds in an open landscape, but may also be affected by the birds own intense foraging activities. However, the measurements that have become available up till now do not cover the whole "climate space" that arctic breeding waders encounter, due to the bias in study sites and the particularities of weather conditions during the few studies that have been carried out. We would like to extend the series of measurements using DLW in incubating waders of more species than hitherto available and under more environmental conditions. Field measurements of DEE involve initial capture of a bird on the nest, loading it with DLW and recapturing the bird after a certain period of time, usually 24-48 hours. There is room for improvement over the earlier studies in monitoring the loaded birds activity budget (using transponders, small radiotags and/or nest/egg temperature recorders) and in assaying the birds physiological status. Apart from mass and size variable, birds could probably be assayed for the thickness of the breast muscle (a heat generating part of the body) and the size of the stomach (as an indicator of the digestive apparatus) using ultrasound. These techniques are under development at NIOZ and the University of Groningen at the moment. Equally, body composition in terms of fat and lean components could be estimated from dilution factors after quantitative DLW injections. It is crucial to simultaneously measure the meteorological variables air temperature, wind speed and global solar radiation, and hence a weather station has to be brought to the study sites to this effect. Fat deposition and basal metabolism of birds preparing for autumn migration Waders need high-performing bodies to cope with their energetically high rate of living. This is reflected in their basal metabolic rate (BMR). The BMR of an animal is the energy it spends at rest (i.e., at night for day-active animals), in thermoneutral conditions, without processing food, and when it is not involved in productive activities like reproduction, moult or growth. The BMR of a bird may be compared with the fuel consumption of a car engine that is running idle. A Formula-One car, that operates at an incredibly high rate also has a high cost of running idle. A standard car with a less impressive engine takes less energy to keep running. As the cost of running idle reflects the potential power of an engine, the BMR reflects the potential rate of work of an animal body. Waders have comparatively high BMR compared to other non-passerine birds (Kersten & Piersma 1987). Moreover, studies of captive Knots have shown that they vary their BMR over the year (Piersma et al. 1995). In addition, waders trapped during the first part of their autumn migration in Arctic Eurasia were found to have higher BMR than their conspecifics at tropical wintering grounds in Africa (Kersten et al. in press, Lindström in press a). This all suggests that waders can adjust the size of their engine which makes sense, since the best solution would be to have a strong engine when circumstances so demand, and a smaller engine during more relaxed parts of the year (for example at wintering grounds in Africa; Klaassen et al. 1990). Although we are actually most interested in the long-term maximum rate of energy expenditure as a measure of adaptations to a high rate of living, this is very difficult to measure, and especially so in a comparable way. Instead, the BMR, which is supposed to reflect the maximum energy turnover potential, is fairly easy to measure, and figures from different investigations can be compared. During TE-94, 24 juvenile waders of five different species were measured for their BMR in a respirometer (Lindström in press a). We want to continue this work by including birds of new species, and of the same species but from another breeding area. Juvenile birds will be caught during the first parts of the autumn migration (mainly August) in portable and walk-in traps. They are then brought to the ship where they will be measured in the respirometer. The BMR values will be compared to those obtained during TE-94 and with data from the migration and the wintering grounds in America and Europe to look for inter- and intra-specific patterns. Whereas it is fairly well known that many (most ?) wader species put on huge energy reserves prior to migration to the Arctic, almost nothing is known about the size of reserves carried by waders prior to departure from the Arctic. This is necessary to know in order to understand the migration strategies adopted (Alerstam & Lindström 1990) and when analysing migration routes. During TE-94 almost 300 juvenile waders were trapped during August, most of them being Little Stints Calidris minuta. It was revealed that also when migrating from the Arctic, substantial energy reserves were put on (Lindström in press b). We now want to collect corresponding data from the Nearctic. Whereas much is known about the size of energy reserves of migration waders further south in America (for example, McNeil & Cadieux 1972, Thompson 1974, Johnson et al. 1989, Driedzic et al. 1993), we know of no such data from the Nearctic region.

In the seventeent and eighteenth centuries intensive European whaling and walrus hunting took place in the waters around Spitsbergen, with many stations on the coast of the islands. The hunt was carried out in areas along the edge of pack ice and is therefore very sensitive to changes in the ice situation and climate. When, around 1650, climate and ice distribution changed, whales moved to the north. The whaling stations in the south of Spitsbergen were abandoned when stations in the north were still functioning. When, later, the ice situation deteriorated in the north as well, the stations were abandoned there too. Shore whaling changed into pelagic whaling. Because of these whaling and walrus hunting activities two very numerous large mammals were largely depleted and almost disappeared from the Spitsbergen waters. The pelagically feeding Greenland Right Whale and the bentically feeding walrus, whose initial stocks are estimated at 46,000 Greenland Right Whales and 25,000 walrus, were eliminated. This elimination has caused a major shift in the foodweb. The plankton feeding seabirds and polar cod strongly increased because of the elimination of the Greenland Right Whale, and the eider ducks and bearded seals increased because of the decrease of the number of walruses. This development has led to the enormous amount of seabird rookeries on the West coast of Spitsbergen.
The ecology and breeding success of the Longtailed skua (Stercorarius longicaudus) and the Brown skua (Catheracta lonnbergi) is studied in a longterm programme. The difference in allometric growth between the different species and populations of skuas is interesting when it is related to the ecology and distribution history of these species and populations. Skuas have a dynamic distribution history and an opportunistic way of living. Populations of the same species in different localities have often a different ecology. Therefore, studies on different populations of the same species are carried out.

Moose (Alces alces) found dead (FD) and hunter-killed (HK) in 1995 on the north slope of Alaska (Colville River drainage) were evaluated for heavy metal and mineral status. Compared to previous reports for moose and domestic cattle, and data presented here from Alaska moose outside the Colville River area, levels of copper (Cu) were determined to be low in hoof, hair, liver, kidney, rumen contents, and muscle for these north slope moose. Iron (Fe) was low in muscle as well. These findings, in conjunction with evidence of poor calf survival and adult mortality prompted investigation of a mineral deficiency in moose (serum, blood, and hair) captured in the spring of 1996 and 1997. Captured males had higher Ca, Zn and Cu levels in hair than captured females. Female moose hair samples were determined to be low (deficient) in Cu, Ca, Fe, and Se with mean levels (ppm) of 2.77, 599.7, 37.4, and 0.30, respectively. Serum Cu level was low, and to a lesser degree Zn was deficient as well. Whole blood (1997 only) was marginally deficient in Se and all animals were deficient in Cu. Based on whole blood, sera and hair, Cu levels were considered low for moose captured in spring 1996 and 1997 in the Colville River area as compared to published data and other populations evaluated in this study. Low levels of ceruloplasmin activity support this Cu deficiency theory. Evidence indicates that these moose are deficient in Cu and other minerals; however, the remote location precluded sufficient examination of animals to associate this apparent deficiency with direct effects or lesions. Renal levels of Cd increased with age at expected levels.

In 1990, the Directorate for Nature Management (DN) established an area for integrated monitoring within Børgefjell National Park, Røyrvik, N Trøndelag. Studies of vegetation-environment relationships in the area was performed by NINA. The area includes both subalpine birch forest and low alpine heath. The new established vegetation investigation included all together 80 different species. This material was processed numerically by using multivariate methods. Indirect gradient analyses were performed using Detrended Correspondence Analysis (DCA) and Local Nonmetric Multidimentional Scaling (LNMDS). Direct gradient analyses were performed by using rescaled hybrid Canonical Correspondence Analysis (CCA). Non-parametric correlation analyses, Kendall’s , were performed between environmental parameters and DCA axis values. The results of the numerical and statistical processing were used partly to provide a description of the vegetational structure in the material and partly to quantify how much each ecological parameters contributed to determination of vegetational structure. This work shows the species distribution along various complex gradients; moisture, nutrient conditions, light etc. The investigation is primarily designed to study vegetation dynamics along these gradients and whether changes in the number of species can be related to changes in physical, biotic and, not least, chemical parameters. Variance analysis was performed to assess to what extent the sample plots tends move in a determined direction from 1990 to 1995. The variation between the years were not significant along the primary complex gradients, but there were a significant displacement of species along the following gradients. The most important species were: Vaccinium vitis-idaea, Melampyrum sylvaticum and Hylocomium splendens), which showed an increase and some cryptogams like Brachythecium reflexum, B. salebrosum and Cladonia ecmocyna which declined.
In 1993, the Directorate for Nature Management (DN) established a new area for the monitoring of terrestrial ecosystems in Dividalen National Park in Troms County. This report presents the reanalysis of vegetation and soil from this terrestrial monitoring area. The area in Dividalen is located in the northern boreal birch forest, in a relatively continental section where the dominant type of vegetation is bilberry-mountain crowberry birch forest (A4c). The structure of the vegetation is analysed by multivariate methods (ordination). In Dividalen all together 131 species were found; 75 vascular plants, 18 mosses, 14 liverworts and 24 lichens. This is a decrease from the number of species recorded in 1993 when 141 species were found in the same mesoplots: 74 vascular plants, 24 mosses, 18 liverworts and 25 lichens. The decrease was not significant for the total number of species or for the total number of vascular plants. However the total number of cryptogames showed a slight significant decrease in number between 1993 and 1998. This may be due to increased cover of several ericoid species. In Dividalen we found no significant changes in vegetation composition for the periode 1993 – 1998 along the first four ordination axes. However, there were changes in mesoplots with high DCA1 values. The changes were in the direction towards lower species richness. Species like Myosotis decumbens, Poa alpina, Solidago virgaurea, Cerastium fontanum and Rumex acetosa ssp. lapponicus showed the largest decrease in these mesoplots. Species that showed the largest increase were Vaccinium vitis-idaea, Mnium spinosum and Polytrichum juniperinum. We have found no relations between these changes and acidification due to deposition of pollutans. Lack of disturbance factors in the area in the last years, which favours an increase in ericoid vegetation, is the probable explanation for the changes.
The study covers many areas of ecotoxicology research on polar bears. Monitoring of POP levels and studies of effects on endocrine disruption, immune system, reproduction, and demography are all parts of the study.
The project aims to describe the environmental status of marine sediments in van Mijenfjorden. This to provide baseline data of contaminants and biodiversity, as well as for monitoring of eventual contamination from industrial activities (coal mining).
