  2. 2. Genome Evolution and Niche Differentiation of Bacterial Endosymbionts

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kirsten Maren Ellegaard; Siv Andersson; Andrés Moya; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; niche; habitat; endosymbiont; gut microbiome; honey bee; Wolbachia; comparative; genomics;

    Abstract : Most animals contain chronic microbial infections that inflict no harm on their hosts. Recently, the gut microflora of humans and other animals have been characterized. However, little is known about the forces that shape the diversity of these bacterial communities. READ MORE

  3. 3. Host-parasite adaptations and interactions between honey bees, Varroa mites and viruses

    University dissertation from ; Dept. of Ecology, Swedish University of Agricultural Sciences

    Author : Barbara Locke Grandér; Sveriges lantbruksuniversitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The ectoparasitic mite, Varroa destructor, has become the largest threat to apiculture and honey bee health world-wide. Since it was introduced to the new host species, the European honey bee (Apis mellifera), it has been responsible for the near complete eradication of wild and feral honey bee populations in Europe and North America.

  4. 4. Insect pollination of oilseed rape

    University dissertation from ; Department of Ecology, Swedish University of Agricultural Sciences

    Author : Sandra Lindström; Sveriges lantbruksuniversitet.; [2017]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. READ MORE

  5. 5. Virus Dynamics in Naturally Varroa-Resistant Honeybee Populations

    University dissertation from ; Department of Ecology, Swedish University of Agricultural Sciences

    Author : Srinivas Thaduri; Sveriges lantbruksuniversitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The ectoparasitic mite, Varroa destructor, together with its associated viruses is the most significant threat to honeybee (Apis mellifera) health world-wide. Since the introduction of varroa to the new host species, the European honey bee (Apis mellifera), it has been responsible for the near complete eradication of wild and feral honeybee populations in Europe and North America.
