1. Phylogenetic studies of Elymus s.s. L. (Poaceae) : plant systematics as a prerequisite for efficient conservation and utilization
Sammanfattning : Elymus (wild-rye), in the tribe Triticeae, is a diverse genus and contains about 150 species growing in a wide range of habitats in temperate areas all over the world. The species are wild relatives to some of the most important cereal crops like bread wheat, durum wheat, rye, and barley. LÄS MER
2. Building knowledge for a forage breeding program on native Festuca species in the highlands of Bolivia
Sammanfattning : Native grasses constitute the most important source of feed for camelids, sheep and cattle in the highlands of Bolivia, where the genus Festuca is one of the major feed components. The two most important species of this region are F. dolichophylla J. Presl (known as “chilliwa”) and F. LÄS MER
3. Pea weevil (Bruchus pisorum L.) resistance and genetic diversity in field pea (Pisum sativum L.)
Sammanfattning : Field pea (Pisum sativum L.) is an important source of protein in developing countries like Ethiopia. However, the production of field pea is hampered by invasive pests like the pea weevil (Bruchus pisorum L.). LÄS MER
4. Epidemiology and population structure of Campylobacter jejuni and related organisms in wild birds
Sammanfattning : Campylobacter jejuni is one of the most common causes to bacterial gastroenteritis in the industrialised world. Also other species of the Campylobacter genus give rise to human infections. C. jejuni occurs in many different animal hosts and can be isolated from water sources. LÄS MER
5. Adaptation and Constraint in the Plant Reproductive Phase
Sammanfattning : Conservatism is a central theme of organismic evolution. Related species share characteristics due to their common ancestry. Some concern have been raised among evolutionary biologists, whether such conservatism is an expression of natural selection or of a constrained ability to adapt. LÄS MER
