1. Rörelsemönster hos öring (Salmo trutta) : En jämförelse mellan vilda och odlade individer i sjön SiljanKandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)
Sammanfattning : Many populations of salmonids are threatened by fragmentation and degradation of spawning habitats. Common remedial measures are habitat restoration and stocking of hatchery fish to support degraded wild populations. Many populations of brown trout in Sweden have been extirpated. LÄS MER
- Master-uppsats, Karlstads universitet/Avdelningen för biologi
Sammanfattning : Urban forests play key roles in animal and plant biodiversity and provide important ecosystem services. Habitat fragmentation and expanding urbanization threaten biodiversity in and around urban areas. Saproxylic beetles can act as bioindicators of forest health and their diversity may help to explain and define urban-forest edge effects. LÄS MER
3. Lämpliga stampopulationer av mellanspett (Dendrocopos medius) för återintroduktion i Linköping, ÖstergötlandKandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi
Sammanfattning : The middle spotted woodpecker (Dendrocopos medius) became extinct in Sweden in 1982. The last population inhabited a fragmented area of 300 km2 and were for a long time a characteristic species for the oak stands of Sturefors and BjärkaSäby, south of Linköping. The reason why the species got extinct depends mostly on habitat fragmentation. LÄS MER
4. Public green corridors in Cochabamba : a conceptual model proposal for green infrastructure in Cochabamba, BoliviaKandidat-uppsats, SLU/Dept. of Urban and Rural Development
Sammanfattning : (1) The urbanization around the world has led a fragmentation of the natural habitats of plant and animal species. The urban structure is generating a growing matrix that is preventing the dispersal of species. This is damaging the biodiversity and is leading to mass extinction. LÄS MER
5. Villain or scapegoat: New perspectives towards understanding the current management of the human-elephant conflict in Sri LankaMaster-uppsats, Lunds universitet/LUCSUS
Sammanfattning : The conflict between humans and elephants (HEC) in Sri Lanka is severe. Due to habitat fragmentation and resource reduction elephants increasingly roam in areas with human settlements. These human-elephant interactions often lead to losses on both sides, which should be prevented. LÄS MER
