  1. 1. A parasitic bivalve affects the interaction between a native and an invasive salmonid

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Brander Isac; [2023-04-18]
    Keywords : Glochidia larvae; Infestation class; General dominance behavior; Dominant subordinate; Strikes;

    Abstract : The glochidia larvae of the freshwater pear mussel parasitize on juvenile brown trout during their maturation into tiny mussels. The parasitation has several negative impacts on the trout, one of the less studied being behavioral effects. READ MORE

  3. 2. 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

  4. 3. Physical microhabitat requirements for Margaritifera margaritifera and the influence of hydro- and morphodynamics on mussel bed stability

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

    Author : Tove Westberg; [2020]
    Keywords : Stream restoration; Freshwater pearl mussel; Microhabitat requirements; Sediment transport; Mussel translocation;

    Abstract : Margaritifera margaritifera is an endangered freshwater pearl mussel with population declines throughout its Holarctic range. Boulder-bed channels with little input of fine sediment in previously channelized streams are abundant in Sweden. Hence, restoration efforts for M. READ MORE

  5. 4. Host - parasite interactions: : the relationship between encystment load of the freshwater pearl mussel (Margaritifera margaritifera) and genetic diversity of its host (Salmo trutta)

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

    Author : Helena Winser; [2015]
    Keywords : ;

    Abstract : The freshwater pearl mussel (FPM, Margaritifera margaritifera) is an endangered bivalve mollusc with an obligatory larval parasitic phase on brown trout (Salmo trutta). The FPM has declined throughout its entire range due to causes such as habitat degradation, eutrophication, acidification, changed hydrology and lack of host fish. READ MORE

  6. 5. Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Kristin Forsell; [2014]
    Keywords : flodpärlmussla; biologiska kvalitetsfaktorer; freshwater pearl mussel; biological quality elements;

    Abstract : The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity.
