Does fish health matter? The Utility of Biomarkers in Fish for Environmental Assessment
(2008-11-28)
Two common strategies to assess exposure to environmental toxicants are to measure chemical concentrations in the environment and to examine the presence of certain species that are known to be sensitive to pollution. The ...
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 ...
The evolution of flat periwinkles Littorina fabalis and L. obtusata emhasizing mitochondrial introgression and restricted recombination
(2008-09-12)
The evolution of species takes in general very long time and different mechanisms are likely to operate during the various stages of this process. Accordingly speciation should be studied at different levels of species ...
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 ...
B-box Proteins in Light-regulated Development in Arabidopsis
(2008-09-26)
COP1 and HY5 are two key regulators of light signaling in plants. Proteins interacting with either could therefore be important regulators of light-dependent development. Previous yeast two-hybrid screens, using COP1 or ...
Lidar Studies of Tropospheric Aerosols and Clouds
(2008-09-22)
An improved description of aerosol and cloud processes is a prerequisite for successful prediction of future climate change. The climate on Earth is controlled by the radiation budget, i.e. the relation between the radiation ...
Studies on the gamma radiation environment in Sweden with special reference to 137Cs
(2008-09-05)
Gamma radiation in the environment today mainly originates from naturally occurring radionuclides, but anthropogenic radionuclides, such as 137Cs, contribute in some areas. In order to assess population exposure in case ...
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 ...
Proterozoic to Quaternary Events of Fracture Mineralisation and Oxidation in SE Sweden
(2008-11-18)
Fracture minerals and altered wall rock have been analysed to reveal the low-temperature evolution, especially regarding redox conditions, of the Simpevarp area, SE Sweden. This area is one of the two areas in Sweden ...
Kemilaborationens bidrag till förståelse - högskolestudentens perspektiv -
(2008-11-14)
Den här studien har som mål att försöka förstå hur laborationen bidrar till att underlätta
studenternas kognitiva arbete att förstå teorin ingående i deras första kemikurs
på akademisk nivå.
Empirin har framförallt sökt ...
