  1. 1. Transcriptomic analysis on freshwater mussels for identification of potential biomarkers to monitor water ecosystems

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Md Mehedi Hasan Joyon; [2020]
    Keywords : ;

    Abstract : Stress-specific expression of cellular proteins in responses to exogenous exposure and resulting physiological alteration provides important insight into the field of ecological research. Due to its habitat, feeding, lifestyle and physiologic properties, mussel has become an important indicative measure of aquatic environment pollution in order to assess effect of these pollution in aquatic life.

  2. 2. Direct poly(A) RNA nanopore sequencing on the freshwater duck mussel Anodonta anatina following exposure to copper : A pilot study

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Erik Engström; [2019]
    Keywords : mussel; hepatopancreas; nanopore; sequencing; RNA; nucelotide; read;

    Abstract : Aquatic ecotoxicology is the study of toxic chemicals and its effects on aquatic biological systems with the aim of minimising threats to human health and ensure self-sustained ecosystems. Freshwater bivalves are excellent sentinels for use in ecotoxilogical research due to their filter feeding properties, stationary lifestyle and inability to regulate body temperature. READ MORE

  3. 3. Mouthpart deformities of Chironomid larvae as an indicator of heavy metal polluted water

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

    Author : Tim Lindström Jonsson; [2019]
    Keywords : Chironomidae larvae; Deformities; Heavy metals; Biomonitoring; Mining; Northern Sweden;

    Abstract : Freshwater ecosystems are under increasing pressure from a variety of contaminants, including heavy metals from mining operations, which can have complex effects that are difficult to evaluate. To detect early warnings from elevated concentrations of metals, organisms are sought to be used as monitoring tools. READ MORE

  4. 4. Natural value assessments – can they predict the species richness of red listed and bioindicator fungi in Fennoscandian coniferous forests?

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Louise Samuelsson; [2017]
    Keywords : Nature conservation; key biotope inventory; natural value assessment; bioindicator; red listed species;

    Abstract : The thesis aims to examine how well two standardised methods in nature conservation, namely natural value assessment and key biotope inventory, perform in terms of recognising an area with a high amount of red listed and bioindicator fungi. The two methods are compared to see if any method is superior to find areas with high presence of red listed and bioindicator fungi and if a larger area automatically means a larger number of species.

  5. 5. Evaluating zinc content in aquatic ecosystem by estimating the responses of diatom biofilm to environmental and biological variables

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

    Author : Anders Lundqvist; [2016]
    Keywords : bioindicator; biofilm; diatom; EPS; zinc; pH; light; nutrients; temperature; time; anion; cation; unstable conditions; cell size; community composition; detoxification mehcanism; bacteria; guild; species; phenotypic plasticity; cell wall; genetic adaptation; interactive model;

    Abstract : Zinc is a common essential metal. At too high exposure it will become toxic. Diatoms have a species-specific cell wall and they are easy to collect and to preserve. When exposed to environmental stress they could have teratological form, which is one of the reasons to have diatom as a bioindicator for metal contamination assessment. READ MORE
