  2. 16. Revealing the architecture and composition of the sperm flagellum tip

    Author : Davide Zabeo; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Structural biology; Microtubules; Electron microscopy; Cryo-electron microscopy; Cryo-electron tomography;

    Abstract : The eukaryotic flagellum is a membrane-bound protruding organelle with a cytoskeleton of microtubules. Flagella are found in unicellular as well as multicellular organisms, performing a variety of functions. READ MORE

  4. 17. Migratory behaviour and adaptive divergence in life-history traits of pike (Esox lucius)

    Author : Petter Tibblin; Per Larsson; Anders Forsman; Asbjørn Vøllestad; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation; evolution; homing; local adaptation; management; phenotypic variation; population divergence; selection; sympatric;

    Abstract : Population divergence shaped by natural selection is central to evolutionary ecology research and has been in focus since Darwin formulated “The origin of species”. Still, the process of adaptive divergence among sympatric populations is poorly understood. READ MORE

  5. 18. Evolutionary ecology of newts

    Author : Jan C. Malmgren; Hanna Kokko; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolution; adaptation; amphibians; salamanders; predation; migration; sexual dimorphism; sex differences; behaviour; conservation; Biology; Biologi; Biologi med ekologisk inriktning;

    Abstract : Sexual dimorphism, predator avoidance and migratory behaviour are adaptive traits that show variation at the population and species level. Such features respond to the environment in the broad sense, that is, when both abiotic and biotic components are included. READ MORE

  6. 19. Genomic studies of contemporary processes in wild populations : with the Scandinavian brown bear as a model

    Author : Anita Norman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Genomic tools can greatly facilitate our understanding of wild populations. For the purposes of ecology and conservation, the most pertinent insights into wild populations are those that are contemporary. READ MORE

  7. 20. Mechanisms of plant root xylem developmental plasticity in response to water deficiency and salt

    Author : Frauke Augstein; Annelie Carlsbecker; Eva Sundberg; Charles Melnyk; Malcolm Bennett; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ABA; developmental plasticity; GA; HD-ZIP III; VND; xylem; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : Plants may be exposed to a variety of different environmental conditions including water deficiency and salt, both affecting the uptake of water into the plant. Water is taken up from the soil by the roots and distributed throughout the plant via the water conducting tissue, the xylem. READ MORE
