11. Phenotypic Plasticity and Adaptation Potential to Salinity in Early Life Stages of the Tunicate, Ciona intestinalis spB
Sammanfattning : Species respond to environmental heterogeneity through a variety of mechanisms such as plasticity, genetic adaptation and phenotypic buffering. Determining how gene flow, scale of environmental heterogeneity and trait heritability influence these responses is important for understanding how these different mechanisms arise, which is a central task in the field of evolutionary biology.

12. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification
Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.

13. Genetic variation and local adaptation in peripheral populations of toads
Sammanfattning : Northern fringe populations generally have low amounts of genetic variation and inhabit habitats where specific adaptations are needed. On the Swedish west coast, the natterjack toad (Bufo calamita) inhabits skerry islands. LÄS MER
14. Ecotoxicological studies on giant clams (Tridacnidae) : Environmental problems and future concerns
Sammanfattning : Giant clams (Tridacnidae; Bivalvia) are described as important framework builders on coral reefs in the Indo-Pacific region. They are phototrophic as they are associated with primary producing zooxanthellae. Populations are low due to over-exploitation and most species are now endangered in many areas. LÄS MER
15. Evaluation on brewery yeast and insect meal (black soldier fly and cricket meal) to replace trash fish in the diet for Asian seabass (Lates calcarifer) in Cambodia
Sammanfattning : Sustainable development of marine aquaculture in Cambodia was studied in this thesis, using Asian seabass as the target species. An initial survey mapped current production practices, geographical occurrence and production volumes of Asian seabass farming in coastline provinces in Cambodia (Preah Sihanoukvill, Kampot and Koh Kong).
