1. Sediment transport in small streams is related to riparian buffer width : a comparison between wide and narrow riparian buffers
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : This study aims to provide information about how different widths of riparian buffers affect the quantity and quality of sediments transported in a small stream after a clear – cut harvest. Small streams have critical influences on downstream rivers and excessive transported sediments can have large negative effects on the aquatic system. READ MORE

2. Nutrient Retention in Constructed Wetlands
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. READ MORE

3. Freshwater bivalves with ecosystem engineering traits : The biodeposition rate of A. anatina and U. tumidus
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : Freshwater bivalves of the family Unionidae have filter-feeding traits that alter freshwater ecosystems on several trophic levels. Filtration of organic and inorganic particulates in the water column transform matter through the mussel’s egestion before it is sequestered in the sediment, making it available as food for benthic invertebrates.

4. Determination of organic phosphorus in soil samples by capillary zone electrophoresis coupled to electrospray ionization mass spectrometry
University essay from Uppsala universitet/Analytisk kemiAbstract : Chemical substances that are either produced by nature or by humankind have a consequence on the environment when they are accumulated to a great extent. One of nature’s major problem is that of the eutrophication of surface waters, which is caused by inorganic and organic phosphorus compounds and, in particular, from a group known as Inositol Phosphates.

5. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium
University essay from Lunds universitet/Geologiska institutionenAbstract : A small lake in north-eastern Scania, southern Sweden, Lake Lyngsjön, reveals a long history of aeolian sand drift based on a 3 meter long sediment sequence covering the last approximately 1400 years. Human impact, primarily through intensified land use and decreased forest cover, has periodically led to increased aeolian sand drift both locally and regionally. READ MORE
