1. Temporal trends of 4-Hydroxychlorothalonil in maternal serum samples, 1997-2015
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : Agricultural fungicides are extensively used for infestation control, resulting in residues of these compounds in food. Human exposure to environmental contaminants might occur via different routes, such as inhalation, skin contact, or ingestion. Exposure to several pesticides has been associated with adverse human health outcomes. LÄS MER
2. Evaluation of restoration efforts in Dalälven - conditions for survival rate of Salmo trutta and Salmo salar
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Rivers are among the most anthropogenically affected ecosystems in the world by irrigation, transportation, channelizing, and hydropower. Habitat restorations have become a popular method to restore the heterogeneity and complexity of rivers aiming for improvement of biodiversity. LÄS MER
3. Estimating a Boat’s Vertical Velocity with Unpositioned 6DOF IMU:s : How sensor fusion and knowledge of the system dynamics can be used to estimate the IMU positions and produce fused estimates
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Longline fishing is a method of fishing that utilizes baited hooks to catch fish in an environmentally friendly way. In order to reduce the number of catch lost while longline fishing, it is of great interest to be able to keep an even tension on the fishing line. LÄS MER
4. Restoration effects on benthic macroinvertebrate diversity and community composition in a river
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Physical restoration efforts are common methods to restore running waters containingdegraded ecosystems due to anthropogenic activities such as irrigation, ditching, dammingand flood prevention. The goal is usually to restore waters to a more natural state, creatingmore physically complex habitats supporting a larger number of species of both fish andinvertebrates, hence increasing biodiversity.

5. A recipe for fish and SNPs : Filling the blanks for conservation genomics of Swedish wels catfish (Silurus glanis) populations
Master-uppsats, Uppsala universitet/Institutionen för ekologi och genetik; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Swedish populations of Wels catfish (Silurus glanis) experienced severe declines during the 19th and 20th centuries. The main causes for the decline were loss of suitable spawning habitat and fragmentation of populations. Currently, three native and two reintroduced populations remain in Sweden. LÄS MER
