  2. 1. Spatial distribution and conservation planning of seabed biological diversity

    Author : Genoveva Gonzalez-Mirelis; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial autocorrelation; ecological classifications; distribution modelling; biotopes; conservation planning; biodiversity surrogates; GIS; spatial ecology; benthos; fjord;

    Abstract : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.

  4. 2. Habitat compensation in nature-like fishways : Effects on benthos and fish

    Author : Stina Gustafsson; Olle Calles; Martin Österling; Jostein Skurdal; Paul Giller; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biocanal; biodiversity; brown trout; freshwater pearl mussel; functional feeding groups; habitat heterogeneity; large woody debris; macroinvertebrates; PIT-tag; salmonids; Biology; Biologi;

    Abstract : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. READ MORE

  5. 3. Ecological succession of benthic macrofauna following disturbance : Effects of contaminants and in situ sediment remediation

    Author : Caroline Raymond; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Joanna Norkko; Gert Van Hoey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Activated carbon; Benthos; Bioturbation; Contaminants; Environmental indices; Environmental monitoring; Environmental quality; Seafloor integrity; Sediment remediation; marin ekologi; Marine Ecology;

    Abstract : More than 70% of the Earth is covered by water, and most of the sea floor consists of soft sediments, such as mud, clay and sand. Thus, soft sediments form one of the most important habitats on Earth, with a high diversity of organisms. READ MORE

  6. 4. Wave energy conversion and the marine environment : Colonization patterns and habitat dynamics

    Author : Olivia Langhamer; Anders Berglund; Jan Sundberg; Andrew Gill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial reefs; benthos; biodiversity; biofouling; colonization; environmental impact; fish; shellfish; Mytilus edulis; renewable energy; wave power; Biology; Biologi; Animal Ecology; Zooekologi;

    Abstract : A wave energy park has been established on the Swedish west coast outside Lysekil and pioneer work about its interactions with the marine environment has been conducted. So far, little is known about the effects of offshore energy installations on the marine environment, and this thesis assists in minimizing environmental risks as well as in enhancing potential positive effects on the marine environment.

  7. 5. Nutrient Stoichiometry in Benthic Food Webs – Interactions Between Algae, Herbivores and Fish

    Author : Antonia Liess; Peter Eklöv; Dag Hessen; Uppsala universitet; []
    Keywords : Ecology; ecologial stoichiometry; periphyton; grazer; benthos; trophic interactions; nutrient; algae; Ekologi;

    Abstract : The aim of this thesis was to identify general structuring mechanisms in benthic food webs within the framework of ecological stoichiometry theory. Ecological stoichiometry is defined as the balance of multiple chemical substances in ecological interactions and explicitly considers the combined dynamics of key elements such as carbon (C), nitrogen (N) and phosphorus (P).
