1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

2. Controls over stream temperature in a northern boreal landscape
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. READ MORE

3. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. READ MORE

4. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Inland waters are important systems for transforming, storing and transporting carbon along the aquatic continuum, but also by emitting carbon dioxide (CO2) and methane (CH4) to the atmosphere. In light of the last decades observed increase in dissolved organic carbon (DOC) in many inland waters across the northern hemisphere, a logical question arise whether other aquatic carbon species display similar trends.

5. Patterns and factors affecting brownification in a boreal river
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : During the last decades a brownification of the lakes and streams in the northern hemisphere has been observed. The change has been attributed to an increase of organic content in the water, leached from the top soil layers, called humic substances. READ MORE
