  1. 1. Predatory processes in Baltic benthos

    Författare :Gunilla Ejdung; Susanne Baden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Sammanfattning : The Baltic soft-bottom community is uniquely simple, with only a few benthic macro-faunal species, and is therefore well suited for mechanistic studies of inter-specific interactions. Two of the dominating organisms in this benthic community are the amphipod Monoporeia affinis and the bivalve Macoma balthica. Field surveys have shown that M. LÄS MER

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

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

    Sammanfattning : 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. 3. Habitat compensation in nature-like fishways : Effects on benthos and fish

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

    Sammanfattning : 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. LÄS MER

  5. 4. Responses of benthic-pelagic coupling to environmental change

    Författare :Per Hedberg; Monika Winder; Martin Kainz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Benthic-pelagic coupling; Stable isotopes; Fatty acids; Baltic Sea; Plankton; Food webs; Benthos; Marine Ecology; marin ekologi;

    Sammanfattning : Changing abiotic factors, like temperature and light are important drivers of seasonality, affecting aquatic ecosystems and organisms annually in a predictable pattern, structuring species composition, growth, reproduction and trophic interactions. As a consequence of human induced climate change, coastal ecosystems are seeing a disruption in the predictability of annual cycles. LÄS MER

  7. 5. Wave energy conversion and the marine environment : Colonization patterns and habitat dynamics

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

    Sammanfattning : 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.
