    Description: The role of substratum surface tension on the colonization process (fouling) on artificial substrata was investigated in Kiel Bay (Western Baltic). The density of organisms from the major groups (bacteria, microalgae, protozoa, macroorganisms) was monitored on test panels after several exposure intervals in two experimental series. The results showed that substrata with a surface free energy of 24 mN/m were initially less densely colonized by representatives of the different fouling groups. The most hydrophobic substrata and those between 31–43 mN/m were heavily colonzied but there was a slight decrease in density towards the most hydrophilic material (glass). After an immersion time of 64 d these differences were not apparent for bacteria, microalgae or protozoa. These results correspond with thermodynamic predictions, which propose minimum bioadhesion on substrata with critical surface tensions between 20–25 mN/m in seawater. In addition, factors other than the surface tension may be important in marine fouling.

    Chemical defence in mussels: antifouling effect of crude extracts of the periostracum of the blue mussel Mytilus edulis (2006)

    Description: Shells of the blue mussel Mytilus edulis remain free of fouling organisms as long as they possess an intact periostracum, and a multiple antifouling defence that comprises a ripple-like microtopography and the production of chemical antifouling compounds has been suggested previously. This study investigates the chemical defence strategy of blue mussels for the first time. Six crude extracts of the periostracum of intact shells were made using solvents of increasing polarity. These extracts were tested against common fouling organisms in laboratory based bioassays. Non-polar and moderately polar fractions showed the highest activities: the diethyl ether fraction strongly inhibited attachment of Balanus amphitrite cyprids and the marine bacteria Cobetia marina and Marinobacter hydrocarbonoclasticus. Attachment of the benthic diatom Amphora coffeaeformis was significantly reduced by the dichloromethane extract, whereas both ethyl acetate and diethyl ether fractions slowed diatom growth. These results provide the first evidence of surface bound compounds that may moderate surface colonisation.

    Ecological lever and interface ecology: epibiosis modulates the interactions between host and environment (2008)

    Description: The properties of the body surface play a crucial role in most interactions of marine organisms. Critical ecological properties such as drag, morphology, uptake and release of radiation and organic matter are linked to the body surface of an aquatic organism. The properties and functions of this interface may be modified substantially by the presence and activities of epibiotic communities. This, in turn, may lead to substantial modulation of the interactions between the organism bearing epiphytes and its environment, with consequences for the relative fitness of the host organism (basibiont) and its interactors, and ultimately, the structure and functioning of the assemblage. Epibiosis may act as an ecological lever via these indirect effects, greatly amplifying or buffering biotic and abiotic stress.

    Decreased depth distribution of Fucus vesiculosus (Phaeophyceae) in the Western Baltic: effects of light deficiency and epibionts on growth and photosynthesis (2008)

    Description: For many coastal areas of the world, a decrease in abundance and depth penetration of perennial macroalgae and seagrasses has been documented and attributed to eutrophication. A surplus of nutrients impairs perennial seaweeds in at least two ways: increased phytoplankton densities reduce the depth penetration of light and in addition filamentous seaweeds and microalgae growing epiphytically shade their perennial hosts. A reduction of depth limit and total abundance has also been observed for the brown seaweed Fucus vesiculosus at many sites in the Baltic Sea. However, in most cases the mechanistic reason for the loss of Fucus has been deduced from observations rather than from experimental evidence. Here, we present results of a two-factorial (water depth/light supply and epibionts) experiment that was run in the Kiel Fjord, western Baltic, from August to October 2005. Performance of F. vesiculosus was recorded by growth and chlorophyll measurements, PI-curves and in situ measurements of the photosynthetic activity as the relative rate of electron transport (rETR). rETR and growth decreased with water depth. Chlorophyll a concentrations increased with reduced light intensities, but this apparently could not compensate for the light deficiency. Epibionts enhanced the negative effect of reduced light conditions on growth. According to these findings we estimated the physiological depth limit of F. vesiculosus in the Kiel Fjord to lie between 4 and 6 m water depth.
