1. Characterization of Novel Solute Carriers in Humans, Mice and Flies : Solute Carriers in a Broad and Narrow Perspective
Sammanfattning : The solute carrier family is the largest family of membrane-bound transporters in humans, with 430 members divided into 65 subfamilies. They transport various substrates across lipid barriers and are vital for absorption, distribution, metabolism and excretion in all cell types in the body. LÄS MER
2. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective
Sammanfattning : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. LÄS MER
3. Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture
Sammanfattning : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. LÄS MER
4. Habitat selection, nest predation and conservation biology in a Black-tailed Godwit (Limosa limosa) population
Sammanfattning : This thesis focuses on a black-tailed godwit (Limosa limosa) population, consisting of 35-40 pairs, that breeds on a grazed shore meadow on SE Gotland, Sweden. The small size of the population makes it more prone to extinction due to chance events, than a larger population.The godwits showed microhabitat preferences when choosing nest sites. LÄS MER
5. Plant ecological studies related to restoration of a degraded ecosystem in central Tanzania
Sammanfattning : Kondoa Irangi area is among the most degraded ecosystems in Central Tanzania as a result of heavygrazing, fire, collection of fuelwood and improper cultivation practices. The restoration process of thisdegraded ecosystem through natural regeneration is slowed by the semi-arid climate of the area combinedwith poor soil nutrient status. LÄS MER
