Egg size evolution and paternal care in pipefishes.
(2010-08-30)In this thesis I explore how sexual selection, sexual conflicts, coevolution with parental care and an environmental selective agent (hypoxia) affect the evolution of different egg characteristics and embryo survival and ... -
Biodiversity and genetic patterns in marine invertebrates
(2010-09-17)Abstract: Systematics based on genetic data has both confirmed and contradicted earlier, morphologically defined species and their relatedness. Morphology does not always correspond to genetic lineages, and this will ... -
New Insights into the Evolution of Bryozoa- An Integrative Approach
(2011-02-17)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 ... -
Paleolimnological reconstructions of fish population changes in acidified lakes
(2011-03-04)This thesis deals with the potential of using subfossil Chaoborus spp. and Daphnia spp. remains preserved in lake sediments to reveal past fish community alterations related to progressive acidification. Sediment cores ... -
Systematics of Marionina (Annelida: Clitellata: Enchytraeidae)
(2011-04-25)This thesis is about species of segmented worms that previously were placed in the genus Marionina Michaelsen, 1890, within the family Enchytraeidae, class Clitellata and phylum Annelida. These species are closely related ... -
From Proteomic Analysis to Biomarker Application - Studies of Carbonyl Reductase in Fish
(2011-09-22)Many anthropogenic substances are present in the aquatic environment, but there is limited information on how this combination of chemicals affects exposed wildlife. To assess the impact of chemicals, a biomarker approach ... -
Environmental, nutritional and endocrine regulation of metabolic processes in fish
(2011-11-18)Due to seasonal variations in temperature and food availability, fish in temperate regions should be able to make metabolic adjustments to ensure that enough energy is available for the maintenance of basal processes. ... -
Tales of the flying earth: The effect of host flyways on the phylogeny of shorebird lice (Phthiraptera: Ischnocera)
(2012-04-05)On the wings, bodies, and heads of most birds there are lice. These lice spend their whole lives on their host, with the exception of the few lice that get the opportunity to transfer from one host to another, typically ... -
Infidelity in Birds – Causes and Consequences of Extra-pair Paternity
(2012-04-13)Forty years ago, more than 90% of bird species were classified as monogamous and not very exciting systems for studies of e.g. sexual selection. Since then, the discovery of extra-pair paternity (EPP) in more than 75% ...
