1. 1. Multiple stressors in rotifer communities: : Effects of predation, climate change, and brownification

   Författare :Huan Zhang; Enhet akvatisk ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; community dynamic; brownification; heat wave; inducible defense; rotifer; plasticity; multiple stressors; Predation; prey;

   Sammanfattning : Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. LÄS MER

3. 2. Assessing environmental and contaminant stressors in a benthic amphipod

   Författare :Therese Jacobson; Brita Sundelin; Tamara Galloway; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple stressors; Reproduction; Temperature; Food; Parasites; Fenarimol; PFOS; TBT; Endocrine disruption; Ecdysteroids; Microsporidia; Microcosm; Crustacea; Amhipoda; Monoporeia affinis; Biology; Biologi; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Organisms in the aquatic environment encounter numerous stressors throughout their lifespan. Some of them are biotic such as food availability, predators and parasites. Others are abiotic and include shifting salinity and temperature change among others. LÄS MER

4. 3. Carving out collective spaces : Exploring the complexities of gender and everyday stressors within rural youth leisure

   Författare :Anne Gotfredsen; Evelina Landstedt; Isabel Goicolea; Sanna Aaltonen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Youth mental health; stressors; leisure participation; gender; femininities; rurality; precarity; space and place; visual methods; ethnography; Public health; folkhälsa; genusvetenskap; gender studies;

   Sammanfattning : Background: The reasons why young people are increasingly suffering frommental health problems, and the opportunities to turn this development aroundare globally debated. Stressors such as education, relationships, futuretrajectories of housing and employment all constitute important factors affectingyoung people’s mental health, leading to stress and achievement pressureespecially among girls and young women.

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

   Författare :Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. A Procedure for Ecological Tiered Assessment of Risks (PETAR)

   Författare :Rosana Moraes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local scale; regional scale; developing country; Brazil; rain forest; multiple stressors; PETAR; ecological risk assessment; causality;

   Sammanfattning : Institutions in developed countries have proposed several Ecological Risk Assessment (ERA) procedures, and the majority of study cases have been carried out there. The use of (often expensive) existing ERA procedures in developing countries is questionable given their limited resources and scarce background information of relevance for risk assessments. LÄS MER
