  2. 1. 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

  4. 2. Surviving the ratchet : Modelling deleterious mutations in asexual populations

    Author : Jonas Söderberg; Otto Berg; Laurence Loewe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical biology; Population genetics; Stochastic modelling; Genome evolution; Muller s Ratchet; Genetics; Genetik; Organism biology; Organismbiologi; Biology; Biologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : One of the most unforgiving processes in nature is that of Muller's ratchet, a seemingly irreversible accumulation of deleterious mutations that all organisms have to deal with or face extinction. The most obvious way to avoid fitness collapse is recombination, though asexual populations usually do not have the luxury of recombining freely. READ MORE

  5. 3. Making Sense of Antisense

    Author : Johan Reimegård; Gerhart Wagner; Hanah Margalit; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sRNA; miRNA; RNA; target prediction; SOLiD siRNA; E.coli; D.discoideum; Biology; Biologi; Bioinformatics; Bioinformatik; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : RNA is a highly versatile molecule with functions that span from being a messenger in the transfer from DNA to protein, a catalytic molecule important for key processes in the cell to a regulator of gene expression. The post-genomic era and the use of new techniques to sequence RNAs have dramatically increased the number of regulatory RNAs during the last decade. READ MORE

  6. 4. Patterns and Processes of Evolution in Sundaland

    Author : Robert-Jan den Tex; Jennifer A. Leonard; Lawrence R. Heaney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Systematics and phylogenetics; Systematik och fylogeni; Genetics; Genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. READ MORE

  7. 5. 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.
