2. 1. A land of one's own : Sami resource use in Sweden's boreal landscape under autonomous governance

   Author : Gudrun Norstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : HUMANIORA; HUMANITIES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; HUMANIORA; HUMANITIES; ALS; archaeology; boreal forest; dendrochronology; forest history; historical maps; interdisciplinary research; lidar; Sami; settlement patterns; ALS; arkeologi; boreal skog; bosättningsmönster; dendrokronologi; historiska kartor; lidar; samer; skogshistoria; tvärvetenskap;

   Abstract : The Sami dominated large parts of boreal Sweden well into the 18th century, and knowledge of Sami subsistence patterns is therefore a key to the region’s forest history. Although much research has been done on Sami resource use and landscape impact, the context is often vaguely understood. READ MORE

4. 2. Grow with the flow : Hydrological controls of riparian vegetation in boreal stream networks

   Author : Lenka Kuglerová; Roland Jansson; Hjalmar Laudon; Birgitta Malm-Renöfält; John Stella; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; boreal forest; channelization; groundwater; Krycklan catchment; liverworts; mosses; riparian buffers; riparian vegetation; river restoration; species richness; stream network; stream size; vascular plants;

   Abstract : What drives species diversity across landscapes is one of the most fundamental questions in ecology. Further, understanding the mechanisms underlying species diversity patterns is important not only for forming and challenging ecological theories but also essential for appropriate landscape management and effective nature conservation.

5. 3. Fate of riverine iron over estuarine salinity gradients

   Author : Simon Herzog; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; iron Fe ; Organic matter; boreal rivers; XAS; DLS; Fe isotope;

   Abstract : Rivers have traditionally not been considered important sources of bioavailable iron (Fe) to the marine waters, since most Fe is lost by salinity-induced aggregation and sedimentation during estuarine mixing. However, recent studies from boreal rivers found a remarkably high Fe stability, probably due to the interaction with organic matter. READ MORE

6. 4. Dissolved and suspended transport of tungsten, molybdenum, and vanadium in natural waters

   Author : Susanne Bauer; Johan Ingri; Carl-Magnus Mörth; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tungsten; molybdenum; vanadium; Baltic Sea; redox cycling; suspended particles; boreal rivers; Applied Geology; Tillämpad geologi;

   Abstract : Some transition metals and metalloids occur primarily as oxyanions in natural waters including antimony, arsenic, chromium, molybdenum, tungsten and vanadium. These oxyanions can pass through cell walls along the same pathways as phosphate or sulfate. Some of these oxyanions are essential for life, but in high concentrations they become all toxic.

7. 5. Fate of perfluoroalkyl acids in the aquatic environment with a focus on mass balance studies

   Author : Marko Filipovic; Urs Berger; Michael McLachlan; Crispin Halsall; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAA; PFOS; AFFF; tap water; ground water; WWTP; mass balance; atmospheric deposition; rivers; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Perfluoroalkyl substances (PFASs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer product applications, such as in aqueous film forming foam (AFFF), durable water repellent clothing, hydraulic oils and food packaging materials.
