1. Diving Deep: Seabird foraging tactics and local prey field
Master-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER
2. The foraging distribution of Cape gannets in relation to Addo Elephant National Park Marine Protected Area
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Seabirds are considered to be the sentinels of the ocean, as they are able to locate their prey in spite of the great heterogeneity of the marine environment. During the breeding season, these central-place foragers not only need to find prey to maintain themselves but also to feed their young. LÄS MER
3. Användning av GPS-halsband på renar i renskötsel
Kandidat-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Under början av 2000-talet började GPS-halsband användas på renar i renskötseln, sedan har användningen ökat och idag förekommer det hos nästintill alla samebyar. GPS-halsband används främst av renskötarna för att kunna följa renhjorden på avstånd, upptäcka eventuella kalvningsplatser samt populära flyttleder som hjorden och renskötarna använder. LÄS MER
4. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER
5. Feeding Live or Dried Black Soldier Fly Larvae (Hermetia illucens) to laying hens – Effects on Immune Traits, Egg Quality, Feather Condition, Body and Organ Weights
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Due to increasing prices and potential scarcity of soybean meal (SBM), there is growing demand for alternative and sustainable protein sources in poultry production. Black soldier fly larvae (BSFL) have proven to be a suitable alternative based on nutritional value and sustainable production. LÄS MER
