2. 1. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests

   Author : Kristoffer Hylander; Christer Nilsson; Bengt Gunnar Jonsson; Ellen Macdonald; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; boreal forest; bryophyte; buffer strip; ecological boundary; edge effect; headwater stream; land snail; liverwort; moss; phytometer; riparian forest; substrate; terrestrial gastropod; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

   Abstract : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. READ MORE

4. 2. Gradients of time and complexity : understanding how riparian and instream ecosystems recover after stream restoration

   Author : Eliza Maher Hasselquist; Christer Nilsson; Stewart Rood; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioassessment; biodiversity; boreal; bryophyte; chronosequence; complexity; diatom; geomorphology; habitat heterogeneity; hydromorphological; macroinvertebrate; macrophyte; nitrogen cycling; river restoration; riparian buffer; stable isotopes; succession; Sweden; Environmental Science; miljövetenskap;

   Abstract : Why evaluations of the ecological outcomes of stream and river restoration have largely reported inconclusive or negative results has been the subject of much debate over the last decade or more. Understanding the reasons behind the lack of positive results is important for bettering future restoration efforts and setting realistic expectations for restoration outcomes. READ MORE

5. 3. Forests, Functions, and Food Webs : Riparian processes through an ecological and molecular lens

   Author : Jeffery Marker; Eva Bergman; Rolf Lutz Eckstein; Denis Lafage; Rachel E. Bowes; Ann Erlandsson; John S. Richardson; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Riparian systems; functional diversity; stable isotope analysis; metabarcoding; Tetragnathidae; Lycosidae; forestry management; prey subsidies; Biology; Biologi;

   Abstract : Riparian systems are critical ecological interfaces that have a significant impact on the surrounding aquatic and terrestrial ecosystems. The riparian and surrounding systems have significant roles in regulating energy flow, providing essential nutrients, and supporting unique species, making them important for ecosystem function.

6. 4. Conceptualizing catchment processes affecting stream chemistry : from basic understanding to practical applications

   Author : Tejshree Tiwari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Maintaining good surface water quality is recognized as one of the greatest challenges for future generations. In northern-latitudes, it is predicted that aquatic ecosystems may experience a large climatic change. READ MORE

7. 5. Digital wet areas mapping

   Author : William Lidberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Wet soil in forested landscapes of the boreal zone is often associated with large open wetlands or peatlands, but it may also be hidden beneath closed forest canopies on drained wetlands or wet strips beside streams known as riparian zones. Since these wet areas are shrouded by canopy they have traditionally been difficult to map from aerial photographs. READ MORE
