  2. 1. Speciation genomics : A perspective from vertebrate systems

    Author : Nagarjun Vijay; Jochen. B.W Wolf; C. Alex Buerkle; Uppsala universitet; []
    Keywords : evolution; speciation; genomics; vertebrate; adaptation; selection; linked selection; crow; killer whale; hybrid zone; transcriptomics; population genetics; behaviour; colouration; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Species are vital entities in biology. Species are generally considered to be discrete entities, consisting of a group of (usually interbreeding) individuals that are similar in phenotype and genetic composition, yet differ in significant ways from other species. READ MORE

  4. 2. Impacts of urbanisation on birds : Disentangling the effects of multiple pollutants on avian behaviour and physiology

    Author : Ann-Kathrin Ziegler; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial light at night; ALAN; antioxidants; great tit; light pollution; LPS; multi-stressor; noise pollution; tropospheric ozone; urbanisation; zebra finch;

    Abstract : Anthropogenic pollution is a pervasive feature of urbanisation, reaching into ecosystems worldwide and posing novel challenges to wildlife. Not surprisingly, differences in behaviour, and physiology, have been found between urban and rural populations. READ MORE

  5. 3. What modulates telomere dynamics? : Inheritance, developmental effects, and physiological challenges

    Author : Ye Xiong; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Telomere; Telomere dynamics; Telomere length; telomere inheritance; Zebra finch; Immune challenge; Heritability; Taenopygia guttata; Physiological parameter;

    Abstract : Telomeres are the conservative sequence repeats located at the end of linear chromosomes that have been the focus of intensive research across many disciplines over the last four decades. They function as a cap to protect the chromosome ends from fusion to other chromosomes and to prevent chromosome degradation. READ MORE

  6. 4. Light-dependent magnetoreception in zebra finches : - from behaviour to receptor

    Author : Atticus Pinzon Rodriguez; Funktionell zoologi; []
    Keywords : magnetoreception; radical-pair process; magnetic compass; orientation; cryptochrome; Taeniopygia guttata;

    Abstract : It is well known that animals can use a wide variety of information sources to help them orient and navigate asthey move over short or long distances. Birds can rely on information from the sun, the skylight polarizationpattern, the stars, landmarks and the Earth’s magnetic field for orientation and navigation. READ MORE

  7. 5. Evolutionary dynamics of migration and breeding in wild birds: genetic architecture, sexual conflicts and evolutionary constraints

    Author : Maja Tarka; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantitative genetics; heritability; intralocus sexual conflict; antagonistic selection; QTL; G-matrix; wing length; arrival date; migration; geolocator; bird; Acrocephalus arundinaceus;

    Abstract : Our knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection.
