  4. 2. The evolution of sexual dimorphism and its genetic underpinnings

    Author : Philipp Kaufmann; Elina Immonen; Tim Connallon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sex-specific dominance; maintenance of genetic variance; sexual antagonism; sex chromosomes; Y haplotypes; artificial selection; sexual dimorphism; Callosobruchus maculatus; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Sexual dimorphism often constitutes the largest phenotypic variance within species but it is puzzling how sexual dimorphisms evolve because most of the genome is shared between the sexes. Sexually antagonistic (SA) selection on a shared genome sets the stage for intralocus sexual conflict. READ MORE

  5. 3. On the endemic Fucus radicans in the Baltic Sea

    Author : Ellen Schagerström; Lena Kautsky; Inga Kjersti Sjøtun; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; seaweed; sexual reproduction; clonality; fragmentation; dimorphism; salinity; distribution; Plant Ecology; växtekologi;

    Abstract : The brown macroalgae Fucus radicans is endemic to the Baltic Sea, but little is known about this newly described species. This thesis investigates the ecology and role of F. radicans within the species poor Baltic Sea ecosystem. The thallus of F. READ MORE

  6. 4. Zygomycetes and cellulose residuals : hydrolysis, cultivation and applications

    Author : Patrik Lennartsson; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zygomycetes; fungi; lignocelluloses; ethanol; fish feed; animal feed; dimorphism; airlift; pretreatment; Biotechnology; Resursåtervinning; Resource Recovery;

    Abstract : Zygomycetes is a class of fungi living worldwide as saprobes, as part of mycorrhizae, and as parasites. Humans have used some zygomycetes for centuries in the production of traditional foods, e.g. Indonesian tempe. READ MORE

  7. 5. Brood sex ratio and sex differences in Tengmalm’s owl : (Aegolius funereus)

    Author : Tim Hipkiss; Gary Bortolotti; Umeå universitet; []
    Keywords : Aegolius funereus; avian CHD1 genes; brood sex ratio; differential mortality; nomadism; northern Sweden; sexual size dimorphism; sibling rivalry; supplementary feeding; vole cycles; zooekologi; Animal Ecology;

    Abstract : Males and females differ in morphology and behaviour, so that selection acts differently on the two sexes. This changes the relative reproductive success of males and females, and it is beneficial for parents to bias the sex ratio of their broods in favour of the sex with the best survival and breeding prospects.
