  2. 1. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution

    Author : Olof Hellgren; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diversity; Plasmodium; bird-migration; transmission; blackfly; host-specificity; host-preference; cytochrome b; DHFR-TS; recombination; phylogeny; Ecology; Ekologi; Genetics; cytogenetics; Genetik; cytogenetik; Parasitology human and animal ; Haemoproteus; Leucocytozoon; Parasitologi människa och djur ; Animal ecology; Djurekologi; Natural science; Naturvetenskap;

    Abstract : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. READ MORE

  4. 2. New Insights into the Evolution of Bryozoa- An Integrative Approach

    Author : Judith Fuchs; Göteborgs universitet; []
    Keywords : Ectoprocta; moss animal; systematics; phylogeny; barcode; COI; gene expression;

    Abstract : Bryozoa is a group of aquatic, sessile invertebrates with circumglobal distribution and includes about 6000 recent species. Bryozoans have an indirect life cycle with a larval stage that settles and metamorphoses into the adult. READ MORE

  5. 3. Evolutionary history of the butterfly subfamily Satyrinae (Lepidoptera: Nymphalidae)

    Author : Carlos Peña; Niklas Wahlberg; Roderic Page; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hostplant use; habitat shift; diversity; grasses; biogeography; phylogeny; Molecular biology; Molekylärbiologi; zoologisk ekologi; Animal Ecology;

    Abstract : I present an overview of the evolutionary history of Satyrinae butterflies (Lepidoptera: Nymphalidae). By using Bayesian and cladistic methods, I develop a phylogenetic hypothesis as a basis for studying the evolutionary history of the group. READ MORE

  6. 4. The plasticity and geography of host use and the diversification of butterflies

    Author : Jessica Slove Davidson; Niklas Janz; Tommi Nyman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nymphalidae; host range; phylogeny; distribution; latitude; phylogeography; local specialisation; colonisation; host shift; polyphagy; speciation; diversification; zoologisk ekologi; Animal Ecology;

    Abstract : Our world is changing rapidly and factors like urbanisation, changed agricultural practices and climate change are causing losses in butterfly diversity. It is therefore of importance to understand the source of their diversity. READ MORE

  7. 5. Effects of Post-Glacial Range Expansions and Population Bottlenecks on Species Richness

    Author : Anders Ödeen; Godfrey Hewitt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Peripatric speciation; bottlenecks; mating asymmetries; Kaneshiro model; Quaternary ice-ages; phylogeny; Motacilla; Motacilla flava; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Animal Ecology; zooekologi;

    Abstract : This thesis relates modern speciation theory to the effects of sudden changes in the range and size of populations. Special reference is made to the climatic oscillations during the Quaternary ice ages. READ MORE
