11. Evolutionary history and local adaptation in Scottish populations of Populus tremula
University essay from SLU/Dept. Of Plant BiologyAbstract : From a subset of P. tremula samples taken from across Europe and China, principal component analysis of genetic variation indicated population structure in the Scottish population compared with the rest of Eurasia. READ MORE

12. Adaptation and variability of Aedes aegypti in relation to food in the southernmost fringe of its distribution - An interdisciplinary approach
University essay from Lunds universitet/Matematik LTHAbstract : Aedes aegypti is the well-spread main vector of dengue and other viral diseases and in means of mosquito control, it is important to understand adaptation and variability within the species. This study has considered eggs of Ae. aegypti from two close regions in the area of Buenos Aires. READ MORE

13. Biodiversity in assisted migration trials : a study comparing the arthropod diversity between different populations of cottonwood (Populus Fremontii) translocated to new areas
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : This study aims at investigating how diversity and community structure of arthropods are affected by assisted migration of foundation species. This is proposed to counter biodiversity loss in the tracks of climate change. By focusing on foundation species, a larger quantity of biodiversity could be protected. READ MORE

14. The Basis of Reproductive Isolation Between Ecologically Divergent Host Plant Races
University essay from Lunds universitet/Examensarbeten i biologiAbstract : Insects and their host plants constitute a considerable proportion of the diversity on earth, and host shifts hence provide excellent study systems to study the process that drive diversification. In this study, I address what the mechanism to achieve assortative mating is in two host races using different host plants to increase our understanding of how reproductive isolation can arise in the face of ecological specialization.

15. Investigation of pollen limitation, inbreeding and outbreeding depression and heterosis in Euphrasia stricta var. suecica on Gotland
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Habitat fragmentation is one of the main threats to semi-natural grasslands all over Europe, causing reductions in both numbers of populations and numbers of individuals withinpopulations. Small isolated populations are particularly vulnerable to fluctuations that reducespopulation size and could lead to loss of genetic variation due to inbreeding depression, orfixation of harmful alleles due to genetic drift.
