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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kirsten Maren Ellegaard; Uppsala universitet.; [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. Insect pollination of oilseed rape

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

  4. 4. Mating structure and nestmate relatedness in primitively social hymenoptera as revealed by microsatellites

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peter A. Thorén; Uppsala universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik; Genetics; genetik;

    Abstract : Mating structure and nestmate relatedness have been estimated in social Hymenoptera with different levels of sociality. Microsatellite markers have been developed for both communal bees (Andrena scottica) and for primetively eusocial wasps (Vespula rufa). READ MORE

  5. 5. Modeling Collective Decision-Making in Animal Groups

    University dissertation from Uppsala : Department of Mathematics

    Author : Boris Granovskiy; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; collective animal behavior; collective intelligence; swarm intelligence; wisdom of crowds; mathematical modeling; stochastic modeling; agent-based modeling; Markov chain models;

    Abstract : Many animal groups benefit from making decisions collectively. For example, colonies of many ant species are able to select the best possible nest to move into without every ant needing to visit each available nest site. READ MORE
