1. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : 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. LÄS MER
2. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?
Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. LÄS MER
3. Effects of native freshwater mussels and leaf debris on benthic macroinvertebrate abundance and diversity : A field experiment with Margaritifera margaritifera in Vasslabäcken, Örebro county
Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Organisms that are part of complex ecosystems interact not only with other organisms but also with their environment, affecting ecosystem functions. In aquatic ecosystems filter feeders affect ecosystem functioning by transferring energy and nutrients from the water to the benthos. LÄS MER
4. Seasonal community dynamics of macroinvertebrates in an Arctic stream
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Arctic ecosystems are amongst the most vulnerable on Earth to ongoing climate change. While the responses to these changes are well studied on land, less is known about how aquatic communities may respond to a warmer arctic. LÄS MER
