  2. 21. Evaluation of macrocyclic lactone resistance in gastrointestinal nematodes of first season grazing cattle

    Author : Marlene Areskog; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Parasitic gastrointestinal nematodes (GIN) are common world-wide among grazing cattle, and cause welfare problems and associated economic losses due to reduced performance of their hosts. In Sweden, the most important GIN include Cooperia oncophora and the more pathogenic Ostertagia ostertagi, which are usually present as mixed infections in first season grazing cattle (FSG).

  4. 22. Linkage maps in studies of genetic variation - examples from Beta vulgaris

    Author : Thomas Kraft; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetics; Genetics; Beta vulgaris; Linkage maps; genetic variation; Genetik; cytogenetik;

    Abstract : Today, most studies of genetic variation utilise molecular markers, making it possible to detect variation at the DNA level. This has greatly facilitated studies of genetic variation in population and evolutionary genetics, systematics and transmission genetics. READ MORE

  5. 23. Habitat characteristics, genetic diversity and conservation concerns for the genus Lithops in Namibia

    Author : Sonja Loots; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The dwarf succulent genus Lithops (Aizoaceae) is endemic to southern Africa, with 16 species in Namibia. Lithops are vulnerable to a variety of threats and assignment of accurate conservation status is difficult due to insufficient information about population parameters and influence of habitat variables.

  6. 24. Resistance to early blight in potato and genetic structure of the pathogen population in Southeast Sweden

    Author : Firuz Odilbekov; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Potato early blight caused by the necrotrophic fungus Alternaria solani is a common foliar disease in many potato-growing regions. Application of fungicides is commonly used to effectively control the disease, although they are undesirable due to environmental consequences. READ MORE

  7. 25. Population ecology and management of waders breeding on coastal meadows

    Author : Richard Ottvall; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; Djurekologi; grazing management; population modelling; demography; genetic structure; population decline; Tringa totanus;

    Abstract : Many wader (Charadrii) populations are declining throughout in Europe, but the underlying causes are often poorly known and diverse. To fully grasp the reasons behind declines in vulnerable wader populations, it is crucial to understand the demography. READ MORE
