1. Genetic processes in small populations : conservation and management considerations with particular focus on inbreeding and its effects
Abstract : .... READ MORE

2. Quantitative genetic variation in declining plant populations
Abstract : The ecological and genetic effects of habitat fragmentation are an issue of major concern in current conservation biology. Habitat fragmentation results in smaller habitat areas and as a consequence smaller and more isolated populations. Many habitats have become fragmented through human activities such as forestry and agricultural development. READ MORE

3. Investigating genetic factors behind the decline of a threatened plant species – Tephroseris integrifolia (Asteraceae)
Abstract : Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. READ MORE

4. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs
Abstract : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. READ MORE

5. Population divergence at small spatial scales : – theoretical and empirical investigations in perch
Abstract : Genetically structured populations arise when gene flow between groups of individuals is hindered by geographical, behavioural or temporal barriers. The identification of such groups is important for understanding evolution and has large implications for conservation concern. READ MORE
