    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE

  4. 7. Climate change effects on migratory birds and on the ecology and behaviour of the willow warbler (Phylloscopus trochilus)

    Author : Johanna Hedlund; Sven Jakobsson; Thord Fransson; Cecilia Kullberg; Sara Cousins; Martin Schaefer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; bird migration; ecology; phenology; bird; avian; willow warbler; chaffinch; land use change; landscape ecology; historical ecology; etologi; Ethology;

    Abstract : Recent global climate change is influencing the behaviour and ecology of species worldwide. Birds are typical systems to study in this context, as they are often migratory and thus subjected to a variety of environmental effects. READ MORE

    Abstract : African elephants are ‘keystone’ species with respect to biodiversity conservation in Africa since they maintain habitats that support several animal communities by changing vegetation structure through foraging and by dispersing seeds between landscapes. Elephants are also ‘flagship’ species because, given their impressive size, they can make people sympathetic and stimulate local and international concerns for their protection. READ MORE

  7. 10. Grassland restoration : Connectivity, plant community change and cows

    Author : Rozália E. Kapás; Sara Cousins; Adam Kimberley; Lars A. Brudvig; Stockholms universitet; []
