2. 1. Climate change impacts on aquatic consumer communities

   Author : Shuntaro Koizumi; Pär Byström; Ryan Sponseller; Jonathan Shurin; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; warming; browning; aquatic consumers; zooplankton; benthic insects; fish; ecosystem experiment; environmental science; miljövetenskap;

   Abstract : Climate change represents a serious threat to aquatic ecosystems, with an increase in lake temperatures already observed that is expected to continue in the near future. Aside from the direct effects of warming, climate change is also partially responsible for the browning of lakes. READ MORE

4. 2. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity

   Author : Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; Marine Ecology; marin ekologi;

   Abstract : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. READ MORE

5. 3. Fish population responses to climate change : Causes and consequences

   Author : Matilda L. Andersson; Peter Eklöv; Brian Hayden; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; browning; climate change; DOC; intraspecific variation; metabolism; resource use; warming;

   Abstract : Lake environments are heterogeneous, and animals show a variety of adaptations to deal with this heterogeneity. Fish often show intraspecific variation in diet, metabolism, and behavior, corresponding to their habitat use. READ MORE

6. 4. Climate change impacts on production and dynamics of fish populations

   Author : Per Hedström; Pär Byström; Jan Karlsson; Peter Eklöv; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Temperature; terrestrial dissolved organic carbon; light extinction; GPP; recruitment; winter mortality; metabolism; cohort competition; fish production; fish biomass;

   Abstract : Ongoing climate change is predicted to increase water temperatures and export of terrestrial dissolved matter (TDOM) to aquatic ecosystems influencing ecosystem productivity, food web dynamics and production of top consumers. Ecosystem productivity is mainly determined by the rates of primary production (GPP) in turn controlled by nutrients, light availability and temperature, while temperature alone affect vital rates like consumption and metabolic rates and maintenance requirements of consumers.

7. 5. Patterns of small-scale coastal fisheries and local fisheries management in Tanzania : adaptation to a changing climate

   Author : Mathew Ogalo Silas; Martin Gullström; Hans W. Linderholm; Mattias Sköld; Patrick Polte; Christina Hicks; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Small-scale fisheries; tropical coastal seascape; nearshore-offshore linkages; coastal ecosystems; fish catch landings; communities; adaptation; climate change; fishing overfishing; Marine Ecotoxicology; marin ekotoxikologi;

   Abstract : Coastal habitats like mangroves, seagrass meadows, coral reefs, and adjacent offshore waters constitute an important part of the tropical coastal seascape. They provide conducive environmental conditions for fish and other marine animals, which serve as food and income for coastal communities around the world. READ MORE
