  2. 1. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

    Author : Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
    Keywords : ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

    Abstract : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. READ MORE

  4. 2. Immunotoxicology in Marine Invertebrates - Effects of Manganese on Immune Response

    Author : Carolina A. M. Oweson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invertebrates; Immune system; Haemocytes; Manganese Mn ; Immunotoxicology; Crustacea; Mollusca; Echinodermata;

    Abstract : Manganese, Mn, is an abundant element in nature, particularly in soft bottom sediments of the oceans and in bedrock. The metal is predominantly bound to the sediment in the colloid state, MnO2. READ MORE

  5. 3. Aquatic organisms on the pill - effects on different organizational levels

    Author : Per Hallgren; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; EDC; EE2; 17α-ethinylestradiol; fish; zooplankton; gastropods; population growth rates; direct and indirect effects; somatic growth; invertebrates;

    Abstract : Communities are composed of organisms that interact with each other and with the non-biological environment. There are also anthropogenic pollutants in the environment that also interact with the organisms. READ MORE

  6. 4. Predator-prey interactions in freshwater systems: The importance of chemical communication

    Author : Kajsa Åbjörnsson; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi; Hydrobiology; trophic cascades; non-lethal effects; benefits; costs; heredity; predator experience; alarmsubstances; dietary cues; amphibian larvae; invertebrates; visibility; fish; behaviour; Predator-prey; chemical cues;

    Abstract : Predator released chemical cues provide a valuable source of information to prey organisms that can be used to alter their behaviour in order to reduce predation risk. In this thesis, I have examined under what circumstances chemical cues may be used by prey, and if prey discriminate between different cues. READ MORE

  7. 5. Metals take flight : Transport and effects across ecosystems

    Author : Johan Lidman; A. M. M. Berglund; Micael Jonsson; Christian Bigler; Brendan Mckie; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metals; aquatic subsidies; passerines; aquatic insects; environmental science; miljövetenskap; ekotoxikologi; Ecotoxicology;

    Abstract : Metal contamination can have severe toxic effects in the ecosystems, resulting in loss of biodiversity, reduced abundance of organisms, and loss of ecosystem services. Traditionally, aquatic ecosystems have been regarded as a sink of metal contamination. READ MORE
