1. 1. The evolution of wetland restoration policy - A case study of Kristianstad Vattenrike

   Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Författare :Alexander Palmér; [2024]
   Nyckelord :Wetlands; Kristianstads Vattenrike; Collective action; Social norms; Policy attributes; Earth and Environmental Sciences; Social Sciences; Agriculture and Food Sciences;

   Sammanfattning : Wetlands are vital for biodiversity, socio-ecological systems, and carbon sequestration, but they present a complex challenge in crafting effective conservation policies. This study investigates a successful case of wetland conservation policy, focusing on the notable achievements of Kristianstad Vattenrike. LÄS MER

3. 2. Evaluation of River Restoration Measures: Interstitial Habitat Variables and Salmon Hatching Rates as Indicators of Success

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Limnologi

   Författare :Jonas Emanuelsson; [2023]
   Nyckelord :;

   Sammanfattning : River ecosystems are some of the most complex ecosystems on Earth, characterized by a highly heterogenous environment which is able to sustain a disproportionally high level of biodiversity in relation to the area of which they occupy. However, anthropogenic activities are encroaching on the highly diverse riverine landscape, threatening freshwater biodiversity. LÄS MER

4. 3. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Marta Holmlund; [2023]
   Nyckelord :wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

   Sammanfattning : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

5. 4. Evaluation of restoration efforts in Dalälven - conditions for survival rate of Salmo trutta and Salmo salar

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Ville Svärd; [2023]
   Nyckelord :Restoration; river; salmonids; benthic fauna;

   Sammanfattning : Rivers are among the most anthropogenically affected ecosystems in the world by irrigation, transportation, channelizing, and hydropower. Habitat restorations have become a popular method to restore the heterogeneity and complexity of rivers aiming for improvement of biodiversity. LÄS MER

7. 5. Dispersal and habitat use of juvenile brown trout (Salmo trutta) following egg stocking : -A case study in the river Rotälven, Sweden

   Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Författare :Jonathan Larsson; [2022]
   Nyckelord :brown trout; egg stocking; dispersal; alevin; fry; parr; redd; habitat preference; Öring; romutsättning; spridning; yngel; parr; habitatpreferens;

   Sammanfattning : Egg stocking in rivers and streams is a common measure to support and re-introduce salmonid populations. To ensure the success of egg stocking programs, knowledge of the early life stages of juveniles including dispersal ability and habitat preferences of fry is a prerequisite. LÄS MER
