  1. 1. Livelihood diversification and land use change in the Sahel: an interdisciplinary analysis of gum arabic in Sudan

    Author : Bodil Elmqvist; LUCSUS; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sudan; Remote sensing; Livelihood; diversification; land use change;

    Abstract : This thesis contributes to the ongoing debate about livelihood diversifi cation and the related question of agriculture’s central role in rural development in the Sahel. It focuses on on-farm diversifi cation during the dry season. The aim is to assess the practice and potential of gum arabic production for smallholders in central Sudan. READ MORE

  2. 2. Microbial evolution: patterns of diversity in aquatic protists

    Author : Ramiro Logares; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; dinoflagellates; biodiversity; lakes; Evolution; diversification; microbes; biogeography;

    Abstract : Little is known about how microbes diversify in nature. In contrast to the more studied multicellular organisms, microbes can have a) huge population sizes, b) high reproductive rates and c) long-distance dispersal. These characteristics can affect their tempo and mode of diversification in ways that still need to be understood. READ MORE

  3. 3. Cross-scale mechanisms and adaptation strategies in Small-Scale Fisheries

    Author : Blanca González-Mon; Maja Schlüter; Beth Fulton; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Small-Scale fisheries; networks; agent-based modelling; trade; migration; mobility; diversification; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Small-Scale Fisheries (SSF) are increasingly facing shocks and changes that affect their capacity to provide food and maintain the livelihoods of millions of people who depend on fishing activities. At the same time, SSF influence and are influenced by interactions across scales, where interdependencies between different places are increasingly evident. READ MORE

  4. 4. Palaeobiology and diversification of Proterozoic-Cambrian photosynthetic eukaryotes

    Author : Heda Agić; Małgorzata Moczydłowska; Shuhai Xiao; Uppsala universitet; []

    Abstract : One of the most important events in the history of life is the evolution of the complex, eukaryotic cell. The eukaryotes are complex organisms with membrane-bound intracellular structures, and they include a variety of both single-celled and multicellular organisms: plants, animals, fungi and various protists.
