1. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests
Sammanfattning : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. LÄS MER
2. A Novel Rearrangement of Allyl Benzyl Ethers and Aspects on the Glyoxylate Ene Reaction
Sammanfattning : This thesis describes an improvement of the glyoxylate ene reaction by using siamyl glyoxaylate and a development of the novel rearrangement of allyl benzyl ethers. The glyoxylate ene reaction was used as a key reaction in a 8-step synthesis of a Taxol A-ring building block. LÄS MER
3. Anatomy of the amphibious liverwort Ricciocarpus natans
Sammanfattning : The purpose of the present investigation was to study the structural adaptations in the terrestrial and aquatic life-forms of Ricciocarpus natans and to obtain more information on the ultrastructure and morphogenesis of cells and tissues in this member of the hepatics. Optical and electron (scanning and transmission) microscopy were combined to elucidate various structural aspects. LÄS MER
4. Functional analyses of growth and development in the liverwort Marchantia polymorpha
Sammanfattning : Land plants developed from a freshwater charophycean algae about 500 million years ago. Today, they consist of two main clades, the vascular plants and the non-vascular bryophytes including hornworts, liverworts and mosses. LÄS MER
5. Grow with the flow : Hydrological controls of riparian vegetation in boreal stream networks
Sammanfattning : What drives species diversity across landscapes is one of the most fundamental questions in ecology. Further, understanding the mechanisms underlying species diversity patterns is important not only for forming and challenging ecological theories but also essential for appropriate landscape management and effective nature conservation.
