  2. 11. Genetic Adaptation and Speciation in Darwin’s Finches and Atlantic Herring

    Author : Fan Han; Leif Andersson; Kjetill Sigurd Jakobsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Darwin s finches; Atlantic herring; Population genetics; Evolution; Ecological adaptation; Speciation; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Bioinformatics; Bioinformatik;

    Abstract : Natural selection acts on existing genetic variation to drive genetic adaptation of organisms to various ecological niches. Interaction between closely related populations, through processes such as competition and hybridization, may either lead to their divergence or population fusion, which has consequences for adaptation and the formation of species.

  4. 12. 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

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

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

    Abstract : 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. READ MORE

  6. 14. Road structures under climate and land use change : Bridging the gap between science and application

    Author : Zahra Kalantari; Folkeson Lennart; Nachtnebel Hans-Peter; KTH; []
    Keywords : Adaptation; extreme rainfall events; runoff; land use; climate change; flood hazard; SRA - Transport; SRA - Transport; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Future changes in climate and land use are likely to affect catchment hydrological responses and consequently influence the amount of runoff reaching roads. Blockages and damage to under-dimensioned infrastructure can be extremely costly for the regions affected. READ MORE

  7. 15. Multivariate Aspects of Phylogenetic Comparative Methods

    Author : Krzysztof Bartoszek; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia; Allometry;

    Abstract : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. READ MORE
