1. 1. Importance of bumble bee community evenness for crop pollination : a simulation analysis of Swedish red clover seed production

   Magister-uppsats, SLU/Dept. of Ecology

   Författare :Vivek Babu; [2018]
   Nyckelord :bumble bee; Bombus; community; evenness; biodiversity-ecosystem function; diversity-stability; diversity-productivity; overyielding; productivity; stability; biodiversity; selection effect; species asynchrony; portfolio effect;

   Sammanfattning : The red clover seed production systems are dependent on pollinators for increase in red clover seed yield and its stability. When compared to domesticated honey bees, the wild bumble bees are highly efficient in pollinating the red clover crop due to its relatively longer tongue length. Longer dependence on single pollinator species i.e. LÄS MER

3. 2. Effect of restoration and surrounding grassland proportion on the dung beetle metapopulation abundance in the fragmented semi-natural grasslands : dung beetles in restored semi-natural grasslands

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Vivek Babu; [2018]
   Nyckelord :dung beetle; grassland proportion; restoration; Aphodius; Geotrupes; abundance; semi-natural grassland; Scarabaeidae; metapopulation; habitat fragmentation; landscape ecology;

   Sammanfattning : The importance of landscape composition surrounding the local habitats is increasingly recognized, especially with goal of enhancing the understanding about its role in various conservation frameworks. The dung beetles which depend on human mediated ephemeral resources (Dung from domestic animal) gives a valuable opportunity for understanding landscape moderated effects of both the landscape structure as well as sensitive grazing management on the local populations of semi-natural grasslands in Sweden.
