1. 11. Studies on spatial and temporal distributions of epiphytic lichens

   Författare :Håkan Lättman; Per Milberg; Jan-Eric Mattsson; Tord Snäll; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Lichens are an important group of organisms in terms of environmental issues, conservation biology and biodiversity, principally due to their sensitivity to changes in their environment. Therefore it is important that we develop our understanding of the factors that affect lichen distribution. LÄS MER

3. 12. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity

   Författare :Zhenhua Sun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macroinvertebrates; Stormwater ponds; DNA metabarcoding; Sediments; High throughput sequencing; Road runoff; Water quality; Aquatic biodiversity;

   Sammanfattning : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. LÄS MER

4. 13. Making space for resilient urban well-being

   Författare :Karl Samuelsson; Stephan Barthel; S. Anders Brandt; Dagmar Haase; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; subjective well-being; affordances; social-ecological urbanism; urban resilience; geographic information system; depression; densification; complex adaptive system; spatial planning; green-blue infrastructure; subjektivt välbefinnande; affordance; social-ekologisk stadsbyggnad; urban resiliens; geografiska informationssystem; depression; förtätning; komplexa adaptiva system; grön infrastruktur; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : This thesis addresses the need for urban landscapes that provide resilient contributions to inhabitants’ well-being while also limiting impacts on the Earth system. It aims to (1) advance a nuanced understanding of how urban environments relate to urban dwellers’ well-being, and (2) formulate guidelines for planning that supports urban dwellers’ well-being and align with global sustainability.

5. 14. The role of young-of-the-year fish in lake ecosystems

   Författare :Pia Romare; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; Rutilus rutilus; Perca fluviatilis; diet-dependent growth; density dependent growth; behavioural cascade; 0 fish behaviour; horizontal echo sounding; biomanipulation; trophic cascade; predation pressure; young-of-the-year fish; trophic interactions; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

   Sammanfattning : Food chain theory is based on consumption; that is, presupposing that the only important interaction between organisms is that they actually meet in an unstructured environment and that one of them is consumed. Recently, studies, including biomanipulation projects, have indicated that trophic interactions are more complex than predicted by food chain theory. LÄS MER

7. 15. Towards the Control of Microplastic Pollution in Urban Waters

   Författare :Emma Fältström; Stefan Anderberg; Sara Gustafsson; Hans Bertil Wittgren; Marinette Hagman; Sverker Molander; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Water pollution has long been considered a challenge in urban areas, and new types of pollution are continuously introduced to society. Urban wastewater and stormwater act as transport pathways of pollution from urban areas to receiving waterways. LÄS MER
