Abstract:
Density-dependent processes are crucial in the regulation of fish populations and strongly influence their resilience to exploitation and exposure to toxic chemicals. Multiple density-dependent processes occur at different stages in the life-cycle of fish, and a general pattern of such processes in the ontogeny of fish has been suggested but not clearly demonstrated in natural populations. This thesis aimed to provide a detailed experimental assessment of density-dependent processes through the entire life-cycle, using laboratory and semi-natural populations of zebrafish, Danio rerio, and to e

Abstract:
In ecological risk assessment (ERA), it is important to know whether the exposure that animal species receive from a chemical concentration exceeds the desired safety level. This study examined several statistical methods currently being used in ecological risk assessment and reviewed several statistical procedures related to this subject in the literature. Two large sample nonparametric tests were developed for this study. Monte Carlo study showed that these tests performed well even when the sample size was moderately large. A real data set was used to show that the new methodologies provide

Abstract:
Land contamination is an acknowledged problem around the world due to its potentially adverse impacts on human health and the environment. Specifically in Europe there are estimated to be 2,500,000 potentially contaminated sites. The risk that contaminated sites pose is investigated by risk assessments. The methods and the models though used in risk assessments, vary both on a national and an international level. In this study, the risk assessment methods and models for polluted soils used in Scandinavia and issued by the Environmental Protection Agencies were compared. The comparison aimed to
