  2. 1. Cooperative Breeding in the Southern Anteater-Chat : Sexual Disparity, Survival and Dispersal

    Author : Jonathan Barnaby; Jan Ekman; Anssi Laurila; Rita Covas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Southern anteater-chat; Myrmecocichla formicivora; cooperative breeding; social evolution; behavioural ecology; delayed dispersal; family living; Africa; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Group-living sets the scene for complex social behaviours such as cooperative breeding, and exploring the factors that shape group-living is crucial in understanding these behaviours. This thesis explores the ecology of a population of the facultative cooperative breeding southern anteater-chat (Myrmecocichla formicivora), a group-living bird species endemic to southern Africa.

  4. 2. Immunogenetic variation along the latitudinal gradient in Scandinavian anuran species : Evolutionary processes, demography and infection

    Author : Maria Cortazar-Chinarro; Jacob Höglund; Anssi Laurila; Yvonne Meyer-Lucht; Helena Westerdahl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi; Biology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : The evolutionary and demographic processes affecting how genetic variation is partitioned and distributed over large geographical scales is of fundamental importance for our understanding of how organisms may adapt to their environments. Northern peripheral populations generally have lower genetic variation and individuals in these populations may therefore face difficulties adapting to their local environment. READ MORE

  5. 3. Physiological and Environmental Processes Influencing Growth Strategies in Amphibian Larvae

    Author : Emma Dahl; Anssi Laurila; Felicity Huntingford; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; growth; growth strategies; amphibians; latitudinal gradient; growth hormone GH ; corticosterone CORT ; breeding phenology; compensatory growth; compensatory strategies; Biology; Biologi; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Cost and benefits of high individual growth rates are likely to vary across different environments leading to geographic differentiation in growth strategies. In ectotherms, habitats constrained by short growing seasons favour rapid growth and development leading to adaptive latitudinal clines in these traits. READ MORE

  6. 4. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea

    Author : Friederike Ermold; Anssi Laurila; Jukka Jokela; Kerstin Johannesson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; thermal adaptation; evolution; Baltic Sea; Biotest Basin; ecological interactions; biological invasions; phenotypic plasticity; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. READ MORE

  7. 5. Clearing up Culex Confusion : A Basis for Virus Vector Discrimination in Europe

    Author : Jenny C. Hesson; Jan O. Lundström; Örjan Östman; Åke Lundkvist; Anssi Laurila; Laura D Kramer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Culex torrentium; Culex pipiens; mosquitoes; vector; ornithophilic; Sindbis virus; West Nile virus; Populationsbiologi; Population Biology;

    Abstract : Mosquito species of the Culex genus are the enzootic vectors for several bird-associated viruses that cause disease in humans. In Europe, these viruses include Sindbis (SINV), West Nile and Usutu viruses. The morphologically similar females of Cx. torrentium and Cx. READ MORE
