  1. 1. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  3. 2. En inventering av bottenfauna i Trönningeån med två biflöden

    Kandidat-uppsats, Högskolan i Halmstad

    Författare :Johannes Glännman; Kalle Ström Töttrup; [2022]
    Nyckelord :Bottenfauna; Trönningeån; ekologi;

    Sammanfattning : Benthic macroinvertebrates are usually small animals living in our lentic and lotic ecosystems, they have been used as indicators of water quality and biodiversity for a long time. Dam removals have become one of the “go-to” conservation methods for restoring connectivity in lotic ecosystems and thereby enabling passage upstream for migrating species. LÄS MER

  4. 3. Fish sampling in lotic water : a study of the efficiency of the novel Nordic multi-mesh Stream Survey Net

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Anders Eidborn; [2017]
    Nyckelord :Fish sampling; NSSN; gill net; fish community;

    Sammanfattning : A free-flowing stream can offer several ecosystem services. Fish are one of these, and are an important resource for society, both as a food source and as a biological indicator of the water quality, which gives knowledge of the overall health of the stream. The lotic environment in fresh water streams is an important habitat for many fish species. LÄS MER

  5. 4. Intra and interhabitat migration in junvenile brown trout and Atlantic salmon in restored tributaries of the Vindelriver

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Matti Erikoinen; [2016]
    Nyckelord :migration; movement; temperature; pit-tag; electrofishing;

    Sammanfattning : Several techniques are used to sample juvenile salmonids in lotic environments. Electrofishing is by far the most commonly used method on the Scandinavian peninsula. LÄS MER

  7. 5. Barriers effect on lotic fish fauna

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Johan Rudin; [2016]
    Nyckelord :migration barriers; ; Lotic fish fauna;

    Sammanfattning : Barriers in running (lotic) waters are known to have serious impacts on fish fauna that would otherwise naturally colonialize them. The two most important effects barriers have on lotic fish fauna are the blockage of fish migration routes and the reduction of water velocity. LÄS MER
