    Sammanfattning : .... LÄS MER

  3. 2. Man-made structures as habitat for marine faunal assemblages

    Författare :Mathias H. Andersson; Sören Nylin; Hans Kautsky; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : Artificial reefs are structures placed in the sea to promote marine life. Although constructions such as oil-rigs, wind farms, bridges and pier pilings are built for other purposes, they could be regarded as artificial reefs as they add new surfaces in the oceans, susceptible to colonization by marine organism.

  4. 3. Offshore wind farms - ecological effects of noise and habitat alteration on fish

    Författare :Mathias H. Andersson; Sören Nylin; Magnus Wahlberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; renewable energy; fish population; artificial reef; attraction vs. production; habitat structure; reef effect; FAD; bioacoustics; noise disturbance; fish behaviour; detection range; threshold; masking; fish communication and hearing; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

    Sammanfattning : There are large gaps in our understanding how fish populations are affected by the anthropogenic noise and the alteration of habitat caused by the construction and operation of offshore wind farms. These issues are of great importance as the construction of offshore wind farms will increase all over the world in the near future. LÄS MER

  5. 4. Effect of climate and land use on niche utilization and distribution of nettle-feeding  butterflies

    Författare :Hélène Audusseau; Niklas Janz; Sören Nylin; Matthew Forister; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Anthropogenic changes in climate and land use are causing a dramatic erosion of biodiversity. To understand this erosion, and predict future transformations of biodiversity, we need to understand better species’ response to these changes at different spatial and temporal scales. LÄS MER

  7. 5. Oviposition strategies in butterflies and consequences for conservation

    Författare :Anders Bergström; Sören Nylin; Jeremy A. Thomas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Oviposition strategies are an important component of life history evolution in insects. Oviposition is a complex behaviour, where females must locate suitable habitat patches, locate oviposition sites, evaluate the quality, and finally decide how many eggs to lay. LÄS MER
