  2. 1. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

    Author : Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. READ MORE

  4. 2. Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change

    Author : Christian Stiegler; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface energy exchange; Arctic and subarctic tundra; climate change; permafrost; eddy covariance; snow cover; micrometeorology;

    Abstract : The surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. READ MORE

  5. 3. Arctic Water System Change and its Interactions with Permafrost and Ecosystem Changes

    Author : Johanna Mård Karlsson; Georgia Destouni; Daqing Yang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; climate change; monitoring; ecosystem shifts; hydrology; hydro-climatic change; permafrost; Physical Geography; naturgeografi;

    Abstract : Climate change and various changes in the landscape itself, such as permafrost thaw, may trigger and mediate substantial changes in the inland water system of the Arctic. Many climate change responses in the Arctic landscape and ecosystems are then related to alterations in the hydrological system. READ MORE

  6. 4. Microbial Communities in Boreal Peatlands : Responses to Climate Change and Atmospheric Nitrogen and Sulfur Depositions

    Author : Magalí Martí Genero; Bo Svensson; Åsa Danielsson; Torben Christensen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Microbial communities; methanogens; plant communities; peatland; temperature; nitrogen; long-term; field experiment; high-throughput sequencing; Microbiella samhällen; metanogener; växtsamhällen; myrar; torv; temperatur; kväve; långtid; fältexperiment; high-throughput-sekvensering;

    Abstract : Myrmarker har en stor roll i regleringen av den globala kolbalansen och koncentrationerna av koldioxid och metan i atmosfären, vilket gör dem till speciellt viktiga ekosystem ur ett klimatförandringsperspektiv. Förändringar av myrmarker genom naturlig utveckling eller antropogen påverkan kan därför få långtgående störningar av myrars klimatreglerande funktion. READ MORE

  7. 5. Sustainable Urban and Regional Development and Related Ecosystem Services and Water-Climate Interactions

    Author : Jessica Faye Page; Zahra Kalantari; Georgia Destouni; Bev Wilson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; urban planning; regional planning; sustainable cities; nature-based solutions; climate change; planning support systems; sustainable development; naturgeografi; Physical Geography;

    Abstract : To accommodate a growing global population while mitigating climate change, urban areas must grow while minimising environmental impacts. To achieve this, a city must be treated as a complex socio-ecological system in which many actors and subsystems act in unclear and unpredictable ways. READ MORE
