  2. 1. Phenotypic Processes Triggered by Biological Invasions

    Author : Philipp E Hirsch; Richard Svanbäck; Skúli Skúlason; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resource polymorphism; phenotypic plasticity; phenotypic divergence; anti-predator responses; Perca fluviatilis; Rutilus rutilus; Dreissena polymorpha; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Individuals within a single population can vary widely in their phenotype e.g. in their body shape. These differences are an important source of biodiversity and they can precede evolutionary divergence within a population. READ MORE

  4. 2. The Invasion of the Zebra Mussel - Effects on Phytoplankton Community Structure and Ecosystem Function

    Author : Rahmat Naddafi; Kurt Pettersson; Peter Eklöv; Willem Goedkoop; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invasive species; Zebra mussel; Invasion success; Selective feeding; Non-lethal effects of predator; Seston stoichiometry; Delayed fluorescence excitation spectroscopy; Phytoplankton dynamics; Trait-mediated indirect interaction; Ecosystem function;

    Abstract : Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. READ MORE

  5. 3. Hidden in the Water : Development of screening strategies to identify new organic contaminants of emerging concern

    Author : Frank Menger; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Man-made chemicals enable and sustain our modern quality of life. These chemicals can, however, become contaminants of emerging concern (CECs). There is currently a considerable lag time between release of chemicals to the environment and their identification as CECs. READ MORE
