2. 1. Systematics of Eucoilini : Exploring the diversity of a poorly known group of Cynipoid parasitic wasps

   Author : Mattias Forshage; Fredrik Ronquist; Göran Nordlander; John Heraty; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eucoila; Trybliographa; Eucoilini; Eucoilinae; Figitidae; Cynipoidea; Hymenoptera; phylogenetics; diagnostics; classification; taxonomy; systematic revision; morphology; Systematics and phylogenetics; Systematik och fylogeni; Entomology; entomologi; systematisk zoologi; Systematic Zoology;

   Abstract : Many animal species are still undiscovered, even in Sweden. This thesis deals with the wasps of the subfamily Eucoilinae (of Figitidae, Cynipoidea), a poorly known group of small parasitoids of Dipteran flies. READ MORE

4. 2. Snake Gourds, Parasites and Mother Roasting : Medicinal plants, plant repellents, and Trichosanthes (Cucurbitaceae) in Lao PDR

   Author : Hugo J. de Boer; Lars Björk; Mats Thulin; Thomas Jaenson; Victoria Reyes-Garcia; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Trichosanthes; Ethnobotany; Similarity of Knowledge; Biogeography; Molecular Dating; Brou; Saek; Kry; Mother roasting; Postpartum healthcare; Parturition; Childbirth; Traditional Medicine; Plant repellents; Fermented fish; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

   Abstract : Background. Traditional plant use was studied in Lao PDR. Research focused on medicinal plant use by the Brou, Saek and Kry ethnic groups, traditional plant repellents against parasitic arthropods and leeches, and the phylogeny and biogeography of the medicinally-important snake gourd genus (Trichosanthes, Cucurbitaceae).  Methods.

5. 3. Evolutionary studies of the Gnetales

   Author : Chen Hou; Catarina Rydin; Richard Saunders; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

   Abstract : The Gnetales consist of three distinct genera, Ephedra, Gnetum and Welwitschia with considerable divergence among them regarding morphological, ecological and molecular characters. A longstanding debate of the similarity between the Gnetales and angiosperms and the unresolved seed plant phylogeny intrigues plant scientists to further investigate the evolutionary history of the Gnetales.

6. 4. Phylogeny and Taxonomy of Subfamily Zygophylloideae (Zygophyllaceae) with Special Reference to the Genus Fagonia

   Author : Björn-Axel Beier; Mats Thulin; Brian Schrire; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Phylogeny; Taxonomy; Zygophylloideae; Fagonia; Biogeography; Biologi; Biology; Biologi;

   Abstract : Members of Zygophylloideae are shrubs, shrublets and herbs of arid and semiarid areas of almost all continents, and many of the species are major components of the vegetation in their areas of distribution. A phylogenetic analysis of Zygophylloideae based on noncoding trnL plastid DNA sequences and morphological data, indicates that the currently recognised genera Augea, Tetraena, and Fagonia, are embedded in Zygophyllum.

7. 5. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter

   Author : Pushan Bag; Stefan Jansson; Fransis Andre Wollman; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scots Pine; Norway spruce; Photosynthesis; Winter adaptation; biologisk kemi; biological chemistry; biology; biologi; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik;

   Abstract : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.
