6. The Ecological and Anthropogenic Impacts of fishing gear in a tropical system : How the size of Spotted Rose Snapper (Lutjanus guttatus) and the ratio of target catch, is influenced by approved fishing gear within a marine area of responsible fishing in the South-Western Gulf of Nicoya, Costa Rica.
Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)Sammanfattning : The oceans are essential for humanity, yet these systems continue to be degraded and suffer from pollution, habitat destruction and overexploitation. The Costa Rican Gulf of Nicoya is a productive gulf that is fished by both large-scale industrial fisheries and small-scale artisanal fishermen. LÄS MER
7. Predicting the future summer range of a declining Arctic waterfowl: the Greenland White-fronted Goose (Anser albifrons flavirostris)
Kandidat-uppsats,Sammanfattning : This study investigates what the future might hold for an endemic goose species, found exclusively in the low Arctic region of West Greenland. Facing a decline since four decades, the Greenland White-fronted Goose constitutes one of few goose populations showing a declining trend. LÄS MER
8. Estimation of Water Depth from Multispectral Drone Imagery : A suitability assessment of CNN models for bathymetry retrieval in shallow water areas
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Aedes aegypti and Aedes albopictus are the main vector species for dengue disease and zika, two arboviruses that affect a substantial fraction of the global population. These mosquitoes breed in very slow-moving or standing pools of water, so detecting and managing these potential breeding habitats is a crucial step in preventing the spread of these diseases.

9. Maternal behaviour of the snow leopard (Panthera uncia) : Den use, post-denning behaviour, position success rate, home range size and daily movement
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Knowledge about a species’ reproductive parameters such as breeding behaviours is a vital building block for essential conservation actions, especially for endangered species. Despite this, there is a considerable knowledge gap about the snow leopard (Panthera uncia) maternal behaviours, as well as the timing of den independence for the cubs. LÄS MER
10. Vilka faktorer påverkar avelsarbetet med snöleoparder i europeiska djurparker?
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Environment and HealthSammanfattning : Snöleoparden (Panthera uncia) har länge ansetts hotad i det vilda, både av tjuvjakt, men på senare tid även av habitatförlust från miljöförändringar och människopåverkan. Sedan slutet av1900-talet så har det funnits ett internationellt samarbete i avelsrutiner, och majoriteten av hållarna utanför kinesiska fastlandet är med i samma stambok för att se till att hålla arten genetiskt diversifierad.
