  1. 6. Evolution of Mimicry and Aposematism Explained: Salient Traits and Predator Psychology

    Författare :Baharan Kazemi; Olof Leimar; Gabriella Gamberale-Stille; Mike Speed; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; imperfect mimicry; mimicry evolution; predator learning; discrimination; generalization; salience; overshadowing; aposematism; warning signal evolution; generalization bias; peak shift; etologi; Ethology;

    Sammanfattning : Aposematic species have evolved conspicuous warning signals, such as bright colors and striking patterns, to deter predators. Some edible and harmless species take advantage of this deterrent effect by mimicking their appearance. Mimicry is a great example of how natural selection produces remarkable adaptations. LÄS MER

  3. 7. Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog

    Författare :Andreas Rudh; Anna Qvarnström; Jacob Höglund; Michael Speed; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; co-evolution; population divergence; natural selection; sexual selection; warning colouration; Oophaga pumilio; Dendrobates pumilio; aggression; explorative behaviour; colour patterns; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals. However, empirical studies on populations experiencing ongoing or recent transitions between these strategies are rare. LÄS MER

  4. 8. Impacts of Speed Limits and Information Systems on Speed Choice from a Safety Perspective

    Författare :Ary P. Silvano; Haris N. Koutsopoulos; Karl-Lennart Bång; Haneen Farah; Johan Olstam; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed choice; urban; roads; speed limits; road characteristics; traffic safety; cooperative systems and warning messages;

    Sammanfattning : Driving a vehicle is considered a demanding task in a complex dynamic environment. For instance, driving a vehicle on urban roads, where motorized vehicles meet vulnerable road users (VRUs) creates a multifaceted environment with difficult trade-offs and interactions. LÄS MER

  5. 9. Need for speed : towards urban planning for rapid transitioning to sustainable personal mobility

    Författare :Varvara Nikulina; Henrik Ny; David Simon; Henrikke Baumann; Göran Broman; Ulf Ranhagen; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; personal mobility; urban planning; rapid transition; sustainability;

    Sammanfattning : The Paris Agreement, the recent Special Report from the Intergovernmental Panel on Climate Change, and the Sustainable Development Goals are examples of United Nation’s facilitated calls for urgent climate action and more generally for a rapid transition of society towards sustainability. Since urban personal mobility is a significant contributor to society’s current sustainability challenges, and considering current trends of population growth and urbanisation, there is a strong need to develop enhanced support for urban planning for rapid transitioning to sustainable personal mobility.

  7. 10. Does speed matter? : the impact of the EU membership incentive on rule adoption in minority language rights protection

    Författare :Anna Parkhouse; Carsten Anckar; Högskolan Dalarna; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hälsa och välfärd; Health and Welfare;

    Sammanfattning : Denna avhandling tar sin utgångspunkt i ett ifrågasättande av effektiviteten i EU:s konditionalitetspolitik avseende minoritetsrättigheter. Baserat på den rationalistiska teoretiska modellen, External Incentives Model of Governance, syftar denna hypotesprövande avhandling till att förklara om tidsavståndet på det potentiella EU medlemskapet påverkar lagstiftningsnivån avseende minoritetsspråksrättigheter.
