  1. 21. Use of phytometers for evaluating ecological restoration

    Författare :Anna L. Dietrich; Christer Nilsson; Martin Wassen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioassay; Channelization; Ecosystem change; Ecosystem response; ekologisk botanik; Ecological Botany;

    Sammanfattning : The increase in ecological restoration can be attributed to valuation of healthyecosystems and concerns for future climate changes. Freshwaters belong among theglobally most altered ecosystems and are restored to counteract human impacts. LÄS MER

  3. 22. Opportunity Windows and Added Value of Gentle Remediation Options for Contaminated Land Management

    Författare :Paul Drenning; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable and Risk-Based Land Management SRBLM ; Ecosystem services; Soil health; Phytomanagement; Soil functions; Cost-benefit analysis; Gentle remediation options GRO ;

    Sammanfattning : Well-functioning, healthy soils are increasingly recognized as vital to human well-being, but soil contamination impairs the capacity of soils to perform their essential functions and provide humans with ecosystem services (ES). Contaminated land poses risks to human health and the environment, which must be managed, but also constitute an important and underutilized land and soil resource for providing ES in urban areas through phytomanagement with gentle remediation options (GRO) – nature-based solutions using plants, fungi, bacteria, and soil amendments to manage risks at contaminated sites while also improving soil functionality.

  4. 23. Forests, Functions, and Food Webs : Riparian processes through an ecological and molecular lens

    Författare :Jeffery Marker; Eva Bergman; Rolf Lutz Eckstein; Denis Lafage; Rachel E. Bowes; Ann Erlandsson; John S. Richardson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Riparian systems; functional diversity; stable isotope analysis; metabarcoding; Tetragnathidae; Lycosidae; forestry management; prey subsidies; Biology; Biologi;

    Sammanfattning : Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function.

  5. 24. European ecosystems on a changing planet : Integrating climate change and land-use intensity data

    Författare :Jan Hendrik Blanke; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LPJ-GUESS; land-use intensity; climate change; carbon; nitrogen; ecosystem functions; trade-offs; vegetation;

    Sammanfattning : Dynamic global vegetation models are mathematical models that provide a bottom-up description of plant communities. They explicitly model physiological and population-level processes such as growth, photosynthesis, carbon allocation, regeneration and mortality. LÄS MER

  7. 25. Brazilian public protection regulations and the preservation of ecosystem services and biodiversity

    Författare :Flavio L. M. Freitas; Ulla Mörtberg; Jan Börner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; Native vegetation; forest conservation; Brazilian Forest Act; Protected areas; Ecosystem services; Biodiversity; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Brazil is significant for sustaining ecosystems services and biodiversity of global importance. However, the expansion of forestry and agriculture to supply national and international markets often results in loss of ecosystem services and biodiversity. Public protection regulations play a crucial role in setting limits for agricultural expansion. LÄS MER
