6. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Den vitryggiga hackspetten har sedan 1950-talet blivit en sällsynt art i det svenska landskapet. Nedgången beror främst på det moderna skogsbruket där barrskog till stor del har ersatt blandbestånd och gammal lövskog. LÄS MER
7. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER
8. 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/LimnologiSammanfattning : 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
9. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing
Master-uppsats, SLU/Dept. of EcologySammanfattning : 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.

10. Habitat use and activity patterns of three Eulemur species in the forest and restoration areas of Ranomafana and Ankafobe, Madagascar
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Anthropogenic deforestation is a major threat to forest environments, as it leads to habitat loss and fragmentation. Many species suffer from these consequences due to reduced resource availability or connectivity. Forests in Madagascar have drastically been reduced in the past few centuries. LÄS MER
