  1. 1. Achieving carbon isotope mass balance in northern forest soils, soil respiration and fungi

    Författare :Björn Boström; Alf Ekblad; Phil Ineson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 13C; Carbon cycle; Ectomycorrhizal fungi; Forest soil; Microbial respiration; Soil respiration; Stable isotopes; Biology; Biologi; Biology; Biologi;

    Sammanfattning : Northern forests contain a large part of the global terrestrial carbon pool and it is unclear whether they will be sinks or sources for atmospheric carbon if the climate warms as predicted. Stable isotope techniques provide unique tools to study the carbon cycle at different scales but the interpretation of the isotope data is impaired by our inability to close the carbon isotope mass balance of ecosystems.

  4. 3. Parks, Policies and People : Nature Conservation Governance in Post-Socialist EU Countries

    Författare :Natalya Yakusheva; Björn Hassler; Magnus Boström; Annica Kronsell; Stacy Vandeveer; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; national parks; Carpathians; Poland; Slovakia; Europeanization; Central Eastern Europe; multi-level governance; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : The national parks in the Carpathian Mountains along the Polish and Slovak border represent encompassing policy agendas that strive to balance biodiversity conservation and social welfare tasks. These countries have, during the last 25 years, undergone rapid transformation from socialist regimes to liberal democracies, and this transformation has affected the political, social and economic spheres.
