    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neotropics; Biodiversity patterns; Speciation models; Andean uplift; K T Event; Biogeography; Phylogenetics; Molecular dating; Rubiaceae; Chloranthaceae; Campanulaceae; Tetrapods; Biological systematics;

    Sammanfattning : Nowhere else on Earth are there so many species of plants and animals as in the Neotropical region. Yet, many questions remain concerning the causes underlying such outstanding diversification. LÄS MER

  3. 7. Landskap och ödesbölen : Jämtland före, under och efter den medeltida agrarkrisen

    Författare :Hans Antonson; Mats Widgren; Ulf Jansson; Stefan Brink; Stockholms universitet; []

    Sammanfattning : This study examines landscape change in the Province of Jämtland during c. 1000–1750 AD. Settlement and arable cultivation are two of the most important sources in this study. LÄS MER

  4. 8. Diversification on an ancient Darwinian island : Evolutionary history of caddisflies (Trichoptera) and other organisms on New Caledonia

    Författare :Marianne Espeland; Kjell Arne Johanson; Niklas Wahlberg; Michael Balke; Stockholms universitet; []
    Nyckelord :New Caledonia; Trichoptera; island; biogeography; phylogenetics; DNA; dispersal; vicariance; adaptation; ultramafic; diversification; new species; environmental factors; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Islands are either of continental or oceanic origin, and the biota of such islands are a result of vicariance and dispersal, respectively. New Caledonia, in the South Pacific, is a part of former Gondwana, but the origin of its biota is heavily debated. LÄS MER

  5. 9. Omnivore population dynamics and trophic behavior : applications for sustainable willow short rotation coppice

    Författare :Anna-Sara Liman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant traits can mediate the interactions between plant feeding trophic omnivores and their herbivore prey via density effects and by altering the omnivore’s trophic behavior (plant vs. prey feeding). LÄS MER

  7. 10. Characterization of IgY for Oral Immunotherapy and Prevention of Pseudomonas aeruginosa Infections in Cystic Fibrosis Patients

    Författare :Elin Nilsson; Anders Larsson; Jane Burns; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical chemistry; Klinisk kemi; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Chicken antibodies, commonly referred to as IgY, have several properties that make them suitable for oral treatment of infections and there is essentially no risk for development of resistance. The overall aims of this thesis were to investigate Anti-Pseudomonas IgY as prophylaxis against infections with Pseudomonas aeruginosa for cystic fibrosis (CF) patients and to characterize the antibody treatment.
