  2. 1. Evolutionary consequences of ecological interactions

    Author : Etsuko Nonaka; Åke Brännström; Göran Englund; Richard Svanbäck; Per Lundberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive dynamics; eco-evolutionary dynamics; ecological speciation; ecosystem; individual based; population dynamics; phenotypic plasticity; predator-prey; sexual selection;

    Abstract : Eco-evolutionary dynamics integrates the reciprocal interactions betweenecology and evolution. These two branches of biology traditionally assumethe other as static for simplicity. However, increasing evidence shows thatthis simplification may not always hold because ecology and evolution canoperate in similar timescales. READ MORE

  4. 2. Multi-level Interactions between Fisheries and Trade : Modeling intertwined social-ecological systems

    Author : Laura G. Elsler; Schlüter Maja; Florian Diekert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multi-level interactions; social-ecological model; trade relationships; complexity; inequality in fisheries; fisheries sustainability; seafood trade; international markets; fisheries collapse; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Sustainable and equitable fisheries are central for addressing the challenges of the UN Sustainable Development Goal 14: Life Below Water. International trade, once presented by Walrasian economists as a panacea for fisheries development, has not markedly decreased poverty and has been related to the overexploitation of marine species.

  5. 3. Species interactions govern evolutionary and ecological effects of population harvesting

    Author : Anna Gårdmark; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; population harvesting; species interactions; ecological community; Ekologi; Ecology; competition; predation; fisheries; spatial dynamics; maturation; population dynamics; life-history evolution; adaptation;

    Abstract : Harvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment.

  6. 4. Interactions between plants, microbes and insects

    Author : Laura J. A. van Dijk; Ayco J. M. Tack; Arjen Biere; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aboveground–belowground interactions; Anemone nemorosa; fungal pathogens; insect herbivores; plant–pathogen–insect interactions; pollination; soil microorganisms; spatiotemporal disease dynamics; Quercus robur; ekologi och evolution; Ecology and Evolution;

    Abstract : Plants interact with an astonishing diversity of insects and microorganisms. Both above- and belowground, plants are attacked by herbivores and pathogens, and interact with mutualists such as pollinating insects and beneficial microorganisms. READ MORE

  7. 5. Global trade, food production and ecosystem support : Making the interactions visible

    Author : Lisa Deutsch; Carl Folke; Karin Limburg; Max Troell; David Waltner-Toews; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; global trade; food production; ecosystem support; resilience; agriculture; ecosystem performance; food consumption; ecological footprint; indicators; aquaculture; agricultural intensification; fishmeal; vulnerability; Sweden; animal feed; critical natural capital; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Modern food production is a complex, globalized system in which what we eat and how it is produced are increasingly disconnected. This thesis examines some of the ways in which global trade has changed the mix of inputs to food and feed, and how this affects food security and our perceptions of sustainability. READ MORE
