  2. 1. Towards co-management of Gialova Lagoon : A Natura 2000 coastal wetland in Messinia, Greece

    Author : Georgios Maneas; Håkan Berg; Stefano Manzoni; Ernsteins Raimonds; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Salinity; wetland restoration; ecosystem services; participatory modelling; social-ecological system; naturgeografi; Physical Geography;

    Abstract : The management of Natura 2000 sites is considered as the cornerstone for the conservation and restoration of biodiversity within Europe. However, protected ecosystems provide a plethora of benefits to local societies, and support the local economy. READ MORE

  4. 2. Biodiversity in fragmented boreal forests : assessing the past, the present and the future

    Author : Håkan Berglund; Bengt Gunnar Jonsson; Jari Kouki; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; bryophytes; CWD; edge effects; fragmentation; fungi; habitat destruction; historical records; indicator; lichens; regression; species-area relationship; value pyramids; woody debris; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The aims of this thesis are to (1) analyze the predictability (indicators) of plant and fungal species diversity in old-growth forests, and (2) assess the history and biodiversity of woodland key habitats (WKHs) and their potential to maintain species diversity in fragmented boreal forest landscapes. Predictability was explored in Granlandet nature reserve, an unexploited landscape composed of discrete old-growth Picea forest patches of varying size isolated by wetland, reflecting conditions of insular biota at stochastic equilibrium.

  5. 3. Function follows Form : Trait-based approaches to climate change effects on wetland vegetation and functioning

    Author : Helen Moor; Jon Norberg; Andrew Gonzalez; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Functional traits; Plant community ecology; Trait distributions; Wetlands; Ecosystem functioning; Ecosystem Services; Climate change; Dispersal; Metacommunity modelling; naturresurshushållning; Natural Resources Management;

    Abstract : Climate change and habitat fragmentation are altering the structure and functioning of plant communities world-wide. Understanding how, why and with what consequences are major challenges of ecology today. Trait-based approaches focus on functional rather than taxonomic identity to facilitate process-based explanation and prediction. READ MORE

  6. 4. Spatial complexity and fit between ecology and management : Making sense of patterns in fragmented landscapes

    Author : Arvid Bergsten; Örjan Bodin; Emily Minor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Connectivity; Conservation; Dispersal; Ecological knowledge; Ecology; Forest; Fragmentation; Graph theory; Institutional fit; Landscape; Management; Metapopulation; Municipal ecologist; Network; Planning; Protected area; Scale mismatch; Social-Ecological; Urban; Wetland; naturresurshushållning; Natural Resources Management;

    Abstract : Avoiding the negative effects of habitat fragmentation on biodiversity is especially challenging when also the management institutions are spatially and administratively distributed. This doctoral thesis introduces five case studies that investigate ecological, social and social-ecological relations in fragmented landscapes. READ MORE
