  2. 1. Biochemical characterisation of landfill leachate toxicity in fish

    Author : Maria Linderoth; Lennart Balk; Ulf Rannug; Cinta Porte Visa; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; landfill leachate; endocrine disruption; fish; Environmental toxicology; Miljötoxikologi;

    Abstract : Deposition remains the most common form of waste disposal in many parts of the world. As a terminus of the products consumed in our society a landfill may contain virtually all sorts of man-made chemicals. Despite this, the harmfulness of landfill leachate has not been extensively evaluated in feral organisms in the environment. READ MORE

  4. 2. Ecological implications of the production of toxic substances by fish killing phytoplankton species grown under variable N:P-ratios

    Author : Niclas Johansson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mixotrophy; grazing; allelopathic interactions; allelopathy; algae; phytoplankton; nutrient limitation; toxicity; Toxic haptophytes; fishkilling phytoplankton; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : The influence of different nutrient conditions on the production of toxins was studied in certain fishkilling haptophytes (e.g. Prymnesium parvum and Chrysochromulina polylepis). READ MORE

  5. 3. Melanosome transfer, photoreception and toxicity assays in melanophores

    Author : Daniel Hedberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colour change; melanophores; melanosome; intracellular transport; pigment transfer; photoreception; toxicity assay; Roundup; glyphosate;

    Abstract : Many animals such as fish and frogs have developed the ability to change colour of their skin to adapt to the environment or to signal to other individuals. This ability is due to specialised skin cells called melanophores. READ MORE

  6. 4. Environmental Monitoring of Refuse Dump Leachate Toxicity in Fish

    Author : Erik Noaksson; Lennart Balk; Louis J. Guillette Jr; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fiskar; miljögifter; Toxicology; Toxikologi;

    Abstract : The global economy is driven by the consumption of goods and materials. Used products are often deposited on refuse dumps, making them potential point sources for all man-made chemicals. Water soaking through landfill waste results in a wastewater termed leachate. READ MORE

  7. 5. Influence of cyanobacterial blooms on coastal fish recruitment

    Author : Karl-Johan Persson; Catherine Legrand; Markku Viitasalo; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; coastal fish recruitment; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Cyanobacteria are the oldest oxygen-producing organisms on Earth and can be found in almost every terrestrial and aquatic habitat. Their long evolutionary history has enabled them to develop diverse adaptations in order to increase their survival in environments subjected to natural and anthropogenic changes. READ MORE
