  1. 1. From geography to genes: evolutionary perspectives on salinity tolerance in the brackish water barnacle Balanus improvisus

    Författare :Anna-Lisa Wrange; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental change; salinity; marine; invertebrates; evolution; plasticity; population genetics; functional genomics; barnacle; osmoregulation;

    Sammanfattning : How species respond to changes in their environment is a fundamental question in biology. This has become an increasingly important issue as anthropogenic effects of climate change and biological invasions have major impacts on marine ecosystems worldwide. LÄS MER

  3. 2. Barnacle Bioadhesive Bonding Formation, Strength and Control

    Författare :Mattias Berglin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barnacle adhesive plaque; poly dimethylsiloxane ; fouling release coatings; bioadhesion; marine biofouling;

    Sammanfattning : The current technology for keeping ship hulls free of marine biofouling requires the use of toxic compounds such as copper, organic biocides and tributyl tin (TBT). The compounds that are released have been shown to have negative effects on non-target organisms, and a worldwide ban of TBT is currently being introduced. LÄS MER

  4. 3. Life history decisions in a changing environment : A long-term study of a temperate barnacle goose population

    Författare :Henk van der Jeugd; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Age at first reproduction; Barnacle goose; Branta leucopsis; Coloniality; Dispersal; Life-history; Mate choice; Population dynamics; Survival; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Animal Ecology; zooekologi;

    Sammanfattning : This thesis shows that climate and increasing population density have profound effects on survival, age at first reproduction, and natal dispersal in a rapidly increasing temperate barnacle goose Branta leucopsis population on Gotland, Sweden.Colony size was found to be the most important fitness-determinant because of strong density-dependent effects on reproduction.

  5. 4. Molecular biology of barnacle Balanus improvisus settlement

    Författare :Anna Abramova; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; barnacles; settlement; transcriptomics; ecdysone cascade; chemosensory receptors; waterborne pheromones;

    Sammanfattning : The aim of this thesis was to investigate molecular mechanisms of various aspects of barnacle settlement, using the acorn barnacle Balanus improvisus. This barnacle is a common fouling species and a model organism for studies in settlement biology, in particular in relation to antifouling research. LÄS MER

  7. 5. Low biocide emission antifouling based on a novel route of barnacle intoxication

    Författare :Emiliano Pinori; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antifouling; Barnacles; ivermectin; low biocide emission; marine fouling; marine paint; ISO 15181; ToF-SIMS;

    Sammanfattning : Marine biofouling can be defined as the colonization of man-made surfaces in seawater by microscopic and macroscopic organisms. This phenomenon can result in great loss of function and effectiveness both for cruising ships and for static constructions. LÄS MER
