26. Plant Population Dynamics of Dodonaea angustifolia and Olea europaea ssp. cuspidata in Dry Afromontane Forests of Ethiopia
Sammanfattning : Human disturbance has led to excessive deforestation and to a very limited forest cover in the Afromontane zone of Ethiopia, which forms a large part of the country. Thus urgent conservation measures are required to ameliorate the situation. LÄS MER
27. Bloom dynamics and population genetics of marine phytoplankton - Community, species and population aspects
Sammanfattning : Phytoplankton are the most important primary producers in the world’s oceans and coastal waters, accounting for nearly half of the global net primary production. Although they are such important organisms, little is known about the ecology and dynamics of phytoplankton. LÄS MER
28. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana
Sammanfattning : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. LÄS MER
29. Population and Community Dynamics in Variable Environments
Sammanfattning : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. LÄS MER
30. Ethnic heterogeneity of the North-Swedish population : its origin and medical consequences
Sammanfattning : Northern Sweden shows a unique population structure with remarkable geographical variations in the distribution of genetic disorders as well as genetic markers like blood groups, serum groups and red cell enzyme types. The present-day population of northern Sweden is a mixture of people of Finnish, Saamish (Lappish) and Central-Swedish origin. LÄS MER
