  2. 1. Sexual Conflict and Gene Expression in Drosophila melanogaster

    Author : Paolo Innocenti; Edward Morrow; Göran Arnqvist; Andrew G Clark; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sexual selection; male-female coevolution; gene expression; transcriptome; microarrays; sexual dimorphism; Drosophila; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Sexual conflict is broadly defined as a conflict between the evolutionary interests of the two sexes. Depending on the genetic architecture of the traits involved, it can occur at the level of male-female interactions or take the form of selection acting to change the mean of a shared trait against the sign of its genetic correlation.

  4. 2. The role of Assortative Mating in the Initial Stages of Sympatric and Parapatric Speciation

    Author : Emma Rova; Mats Björklund; Göran Arnqvist; James Mallet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Callosobruchus maculatus; host fidelity; assortative mating; inbreeding; experimental evidence; sympatric speciation; parapatric speciation; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Divergence in the face of gene flow is perhaps the most wildly disputed subject among researchers through time. The debate is an old one and we find its origin as far back as the era of Darwin. READ MORE

  5. 3. Spatial Modelling of Coastal Fish – Methods and Applications

    Author : Göran Sundblad; Ulf Bergström; Alfred Sandström; Peter Eklöv; Christian Möllmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; habitat; niche; species distribution modelling; juvenile; fish; larvae; spawning; Marine ecology; Marin ekologi; NATURAL SCIENCES; NATURVETENSKAP; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biology with specialization in Limnology; Biologi med inriktning mot limnologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Limnologi; Limnology;

    Abstract : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. READ MORE

  6. 4. Age-specific trade-offs in life-history evolution

    Author : Martyna K. Zwoinska; Alexei Maklakov; Marjo Saastamoinen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; life history; trade-off; learning; aging; sex differences; dispersal; Caenorhabditis; Drosophila; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Trade-offs prevent selection from driving all fitness-enhancing traits towards values that would maximize fitness. Life-history trade-offs, such as the one between survival and reproduction are well-studied, yet trade-offs can also involve behavioural or cognitive traits. READ MORE

  7. 5. Speciation and Metabolic rate : Insights from an avian hybrid zone

    Author : S. Eryn McFarlane; Anna Qvarnström; Jenny Boughman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resting metabolic rate; life history; hybridization; speciation; reproductive isolation; Ficedula flycatcher; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. READ MORE
