2. 1. 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.

4. 2. Asymmetries : Conceptualizing Environmental Inequalities as Ecological Debt and Ecologically Unequal Exchange

   Author : Rikard Warlenius; Humanekologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental justice; Ecological debt; Ecologically unequal exchange; Environmental history; Ecological Marxism; Ecological economics; World system analysis;

   Abstract : In this compilation thesis, consisting of six papers and an introductory chapter, the concepts of ecological debt, climate debt, ecologically unequal exchange, and unequal carbon sink appropriation are at the centre. Their intellectual and political histories are traced to environmental justice movements, ecological economics and neo-Marxist economics. READ MORE

5. 3. On The Big Challenges of a Small Shrub : Ecological Genetics of Salix herbacea L

   Author : Andrés J. Cortés; Karrenberg Sophie; Christian Lexer; John Pannell; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fine-scale environmental variation; migration; adaptation; snowmelt timing; Biologi; Biology;

   Abstract : The response of plants to climate change is among the main questions in ecology and evolution. Faced with changing conditions, populations may respond by adapting, going extinct or migrating. Fine-scale environmental variation offers a unique mosaic to explore these alternatives. READ MORE

6. 4. Management Practices for Dealing with Uncertainty and Change : Social-Ecological Systems in Tanzania and Madagascar

   Author : Maria Tengö; Thomas Elmqvist; Monica Hammer; Carl Folke; Kamaljit Bawa; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; resilience; ecosystem services; local ecological knowledge; traditional ecological knowledge; ecosystem management; agroecosystems; dry tropical forest; social institutions; forest regeneration; sacred forests; taboos; community conservation; Southern Madagascar; Androy; Iraqw; management practices; habitat loss; small reserves; human-dominated ecosystems; social-ecological systems; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Abstract : The development of human societies rests on functioning ecosystems. This thesis builds on integrated theories of linked social-ecological systems and complex adaptive systems to increase the understanding of how to strengthen the capacity of ecosystems to generate services that sustain human well-being.

7. 5. Sexual Selection and Adaptation to Novel Environments

   Author : Ivain Martinossi-Allibert; David Berger; Göran Arnqvist; Lukas Schärer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sexual selection; Environmental change; Sexual conflict; Environmental stress; Adaptation; Adaptive landscape; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

   Abstract : The work included in this thesis aims at exploring the environmental sensitivity of benefits and costs of sexual selection through a combined empirical and theoretical effort, to increase our understanding of the impact of environmental change on sexually reproducing populations.Can sexual selection promote adaptation to novel environments? Sexual selection for good genes should accelerate adaptation by granting higher reproductive success to individuals of high genetic quality. READ MORE
