1. 1. Restoration effects on benthic macroinvertebrate diversity and community composition in a river

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Fredrik Laggar; [2023]
   Keywords : Benthic invertebrates; diversity; communtiy composition;

   Abstract : 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.

3. 2. As I live and breathe! : The effects of hypolimnic oxygenation on benthic macroinvertebrate and zooplankton assemblages

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Rashid Kadhim; [2022]
   Keywords : lake hypoxia; benthic macroinvertebrates; chironomids; zooplankton;

   Abstract : Exacerbated deep-water hypoxia, brought about by anthropogenic-derived dissolved organic carbon (DOC) input, has potentially detrimental impacts on organisms residing in freshwater ecosystems. Oxygenation of the water column is a potential management strategy to mitigate this impact, and used to alleviate DOC induced oxygen depletion. READ MORE

4. 3. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Lara Sánchez Calderón; [2022]
   Keywords : aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

   Abstract : 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

5. 4. Effects of native freshwater mussels and leaf debris on benthic macroinvertebrate abundance and diversity : A field experiment with Margaritifera margaritifera in Vasslabäcken, Örebro county

   University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Author : Kai Sven Onken; [2021]
   Keywords : bivalve; functional role; habitat modification; decomposition; biodeposition;

   Abstract : 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. READ MORE

6. 5. Macroinvertebrate sampling in hydropeaking rivers : Testing Hester-Dendy samplers in a laboratory environment using different flow conditions

   University essay from Karlstads universitet/Avdelningen för biologi

   Author : Mattias Hansson; [2020]
   Keywords : hydropower; bioassessment; benthic macroinvertebrates; biotic indicator; vattenkraft; biologiska bedömningsgrunder; bentiska makroevertebrater; bioindikator;

   Abstract : Degraded rivers and streams caused by disturbances have created a need for reliable tools to assess the ecological status of such ecosystems. Numerous methods and programs have been developed to assess ecological status using biological indicators, benthic macroinvertebrates are the most commonly used biotic indicator. READ MORE
