Melanosome transfer, photoreception and toxicity assays in melanophores
(2009-10-02)Many animals such as fish and frogs have developed the ability to change colour of their skin to adapt to the environment or to signal to other individuals. This ability is due to specialised skin cells called melanophores. ... -
Evolution of annelid diversity at whale-falls and other marine ephemeral habitats
(2009-09-03)When whales die and sink to the sea-floor, they provide a sudden, enormous food supply to organisms in the vicinity. At first, larger mobile scavengers remove the flesh, but also when only the bones remain, the whale-fall ... -
Control of bioluminescence. Operating the light switch in photophores from marine animals
(2009-02-02)Physiologically controlled photocytes, capable of producing bioluminescence, are a common feature in the ocean among animals ranging from cnidarians to fish. The aim of this thesis was to study and compare the nature of ... -
Alkali-containing aerosol particles-release during biomass combustion and ambient air concentrations
(2009-01-22)Air pollution in the form of particles has considerable influence on human health and climate. Atmospheric aerosol particles arise from direct emissions of particles and from the conversion of certain gases to particles ... -
Predation and shorebirds: predation management, habitat effects and public opinions
(2009-01-09)Many shorebird populations are rapidly declining and a high nest predation rate is one of the threats facing these populations. Thus, factors that affect predation and how to manage it in an effective way are receiving ... -
Ecological genetics of inbreeding, outbreeding and immunocompetence in Ranid frogs
(2008-11-21)Using artificial fertilization, I crossed frogs from different populations to evaluate fitness consequences for the offspring from an inbreeding-outbreeding perspective, and to evaluate quantitative genetic effects on ... -
Growth hormone and somatolactin function during sexual maturation of female Atlantic salmon
(2008-10-31)Background and aims: The growth hormone-insulin-like growth factor I (GH-IGF-I) system is known to act during sexual maturation of female salmonids, but the specific roles are not known. Somatolactin (SL) is a pituitary ... -
Haematopoietic and proteomic responses to wounding stress in the common sea star Asterias rubens
(2008-10-01)Dissertation Abstract Holm, Kristina (2008). Haematopoietic and proteomic responses to wounding stress in the common sea star Asterias rubens. Department of Zoology, University of Gothenburg, Sweden Many species of ... -
Relationships between nomenclature, phylogenetics and systematics
(2008-09-01)Systematists have become increasingly aware of the limits imposed by the current system of nomenclature for accurately representing evolutionary relationships and managing efficiently names associated with clades. In ... -
Oxidative Damage in Fish Used as Biomarkers in Field and Laboratory Studies
(2008)Many toxic xenobiotics entering into the aquatic environment exert their effects through redox cycling. Oxidative stress, incorporating both antioxidant defences as well as oxidative damage, is a common effect in organisms ... -
The intestinal epithelium of salmonids : transepithelial transport, barrier function and bacterial interactions
(2006)The salmonid intestinal epithelium is important for growth and health of the fish. The epithelium is exposed to a multitude of internal and external factors that can influence its function. During the parr-smolt transformation ...
