“…On the other hand, at the microscopic level, the wide surfaces of the ommatidia apparently represent an attractive substratum for the attachment of invertebrate larvae/algal zoospores. While it is usually assumed that mechanical cleaning mechanisms keep these surfaces clean, our detailed investigation of their micro-and nanotopographies indicates that these may be compatible with prevention of biofilm formation that influences the subsequent attachment of other biofoulers [27][28][29][30][31][32].

Marine biofouling causes problems for technologies based on the sea, including ships, power plants and marine sensors. Several antifouling techniques have been applied to marine sensors, but most of these methodologies are environmentally unfriendly or ineffective. Bioinspiration, seeking guidance from natural solutions, is a promising approach to antifouling. Here, the eye of the green crab Carcinus maenas was regarded as a marine sensor model and its surface characterized by means of atomic force microscopy. Engineered surface micro-and nanotopography is a new mechanism found to limit biofouling, promising an effective solution with much reduced environmental impact. Besides giving a new insight into the morphology of C. maenas eye and its characterization, our study indicates that the eye surface probably has antifouling/fouling-release potential. Furthermore, the topographical features of the surface may influence the wettability properties of the structure and its interaction with organic molecules. Results indicate that the eye surface microand nanotopography may lead to bioinspired solutions to antifouling protection.

“…Prior to onset of the experiment, colonies were placed overnight in aerated seawater aquaria under total darkness. The following morning, the colonies were exposed to light for one hour, in order to induce larval release [30]. The larvae congregated on the water-surface, towards the light source and were then collected.…”

Abstract:The application of nano-structured compounds has been increasing rapidly in recent years, in several fields. The use of engineered nano-materials as carriers of antifouling compounds is just beginning and already reveals clear advantages compared to bulk active compounds, such as slowed and controlled release, novel functionality, and high loading capacity. This present study assesses the antifouling efficacy of two nanostructured materials, spherical mesoporous silica nanocapsules (SiNC) and Zn-Al layered double hydroxides (LDH), loaded with two commercial biocides, zinc prithione (ZnPT) and copper pyrithione (CuPT). The study used adult mussels from three geographical regions, the Atlantic Ocean, Mediterranean Sea, and the Red Sea, to examine the efficacy of the innovative compounds. The efficacy of these compounds on larvae of the bryozoan Bugula neritina from the Mediterranean Sea and the Red Sea was also examined. The results of this study demonstrated the environmentally friendly properties of unloaded LDH against the two-model systems, adult mussels or bryozoan larvae. ZnPT entrapped in LDH demonstrated the most effective antifouling compound against the two model systems. A comparison of the impact of the two compounds on macrofouling organisms from the different marine habitats examined in this study indicates a distinction associated with the organisms' different ecosystems. The Red Sea mussels and bryozoans, representing a tropical marine ecosystem, yielded the highest efficacy values among tested Atlantic Ocean and Mediterranean Sea mussels and bryozoans.

“…Larvae of most fouling organisms (including barnacles and tubeworms, which were prominent here) attach more readily to biofilmed surfaces than to clean, non-biofilmed surfaces (e.g. Brancato & Woollacott 1982, Hills & Thomason 1996, Wieczorek et al 1996, Wieczorek & Todd 1997, Hamer et al 2001). This indicates a general pattern of facilitation by bacterial biofilms, although negative effects have often been reported (e.g.…”

Recruitment in epifaunal communities: an experimental test of the effects of species composition and age

A key prediction to emerge from community assembly models is that resistance to invasion increases as the community matures. Three epifaunal communities of differing age were developed upon artificial substrata in the Firth of Forth, Scotland, to examine whether community age influenced the rate of establishment of new recruits. Four repeat experiments assessed the numbers of species and individuals invading a controlled amount of free space in these communities. The oldest communities were invaded by the smallest mean number of species in each experiment although these differences were significant for only 1 experiment. Multiple regression showed that age was the most significant predictor variable of the percentage coverage of new species. Because there were no significant effects on communities only a few centimetres away, the mechanisms by which community age controlled invasion in these experiments operate over small spatial scales. These data support the prediction that older communities are more resistant to invasion, but only if the term invasion includes further recruitment of species already present in the community. However, the experimental design does not distinguish between the effects of age per se, and those of different assemblage sequences. As expected, species responded in different ways to community age, and species composition played an important role in determining the success of invasion.KEY WORDS: Community · Age · Recruitment · Invasion · Assembly models · Successional theory Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 307: [49][50][51][52][53][54][55][56][57] 2006 tance to invasion increases as the community matures (Post 1983, Post & Pimm 1983, Drake 1985, Kokkoris et al. 1999). This prediction is consistent with the models of succession described by Connell & Slatyer (1977), and is thus one of the more robust predictions to arise from assembly theory. Following Diamond (1975), Belyea & Lancaster (1999) inferred that the proportion of available resources consumed increases as species invade, and theoretically older communities should be more efficient and more difficult to invade. This appropriation of available resources and niche space is the mechanism underlying the increasing resistance to new recruitment in most models.The main driving force in the development of epifaunal sessile communities is competition for primary space, which is often a limiting factor (Dayton 1971). Space is likely to constitute a limiting resource because of the minimum requirements for attachment, feeding and growth of sessile organisms and because these species cannot move: competition for space in sessile species can still be intense even when the resource (primary space) is not strictly limiting (that is, preempted) (Turner & Todd 1993). As communities age, and the primary free space available for colonisation diminishes, community development can be regarded as a species-by-species replacement process that Greene & Schoener (1982) likene...
