1. Metals in biota

National Environmental Monitoring in Sweden. Monitoring of heavy metals in fish is performed in 110 trend lakes in Sweden. Annual sampling is carried out in 32 lakes, of which seven are in AMAP area. Three fish species have been selected: Arctic char (Salvelinus alpinus), Northern pike (Esox lucius), and Perch (Perca fluviatilis). A selection of metals is analysed in prepared samples of muscle and liver tissue. Analysed metals in liver are : Al, Ag, As, Bi, Cd, Cr, Cu, Ni, Pb, Sn and Zn. In muscle samples Hg and stabile isotopes δ 15N, δ 13C are analysed.

2. National Survey of Forest Soils and Vegetation

 

This project has been divided into two new projects: The Swedish Forest Soil Inventory and the Swedish National Forest Inventory.

The Swedish National Forest Inventory has the task of describing the state and changes in Sweden's forests. The inventory gathers basic information on forests, soils and vegetation. It includes most aspects concerning soils, for example: soil types, soil chemistry including organic matter, water conditions and content of stones and boulders. Acidification, nitrogen deposition and the contribution by soils to climate change are some of the current issues dealt with. Regularly reported variables are: forest state, injuries, and growth, logging operations, new forest stand, and environmental assessment. Invented variables on permanent sampling plots include: position in the landscape, field vegetation, site conditions, soil sampling, assesment of soil characteristics, chemical analysis of soil in O-, B-, BC- and C-horizons.

3. Metals in mosses

National Environmental Monitoring Programme in Sweden. The objective is to follow the deposition of heavy metals over Sweden by the analyses of their concentration in two selected species of moss. The selected species are: Red-stemmed Feather-moss (Pleurozium schreberi) and Mountain Fern Moss (Hylocomnium splendens). Preferred specie: Red-stemmed Feather-moss (Pleurozium schreberi). Metals adsorbed by mosses almost exclusively come from the air and metal concentration in mosses are therefore seen as a proxy for metal deposition. Analysed elements are: Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, V, Zn (2015). The moss samples are taken from over 600 stands across Sweden.

4. Lakes; Chemistry

Annual measurements of physical, chemical, and biological variables are taken in small to medium sized, mostly minimally disturbed lakes, situated across the country. Of the 108 lakes that are part of the Trend Station Lake monitoring programme, 20 are situated in AMAP area. The main aim of the monitoring programme is to document long-term changes related to global or regional change and human-generated stressors. To complement the Trend Station Lake monitoring programme, national lake surveys provide spatial data needed to determine regional patterns, and coupled with time-series data, changes in surface water quality. The National Lake Survey (the Surveillance Stations, re-sampled stations) programme for lake water quality, started in 2007 and results in data of all Swedish lake conditions. Each year some 800 new lakes are sampled to determine chemical and physical conditions; lakes are resampled at 6 year intevals. 4824 lakes are sampled in the country during a six-year sampling cycle, with 1270 situated in AMAP area. The variables included in the Trend Station Lake monitoring programme include water chemistry, fish, phytoplankton, macrophytes, zooplankton, and benthic invertebrates, whilst the National Lake Survey is focused solely on chemical and physical parameters.

5. 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”

6. FUVIRC-Finnish Ultraviolet International Research Centre

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.

7. 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.

8. 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.
