Humans depend on biodiversity in myriad ways, yet species are being rapidly lost due to human activities. The ecosystem services approach to conservation tries to establish the value that society derives from the natural world such that the true cost of proposed development actions becomes apparent to decision makers. Species are an integral component of ecosystems, and the value they provide in terms of services should be a standard part of ecosystem assessments. However, assessing the value of species is difficult and will always remain incomplete. Some of the most difficult species' benefits to assess are those that accrue unexpectedly or are wholly unanticipated. In this review, we consider recent examples from a wide variety of species and a diverse set of ecosystem services that illustrate this point and support the application of the precautionary principle to decisions affecting the natural world.

“…3 In full-scale power trials for a naval frigate, 4 it has been found that fouling, mainly in the form of biofilms, caused an increase of 8%-18% in drag. Schultz, Swain, and co-workers [5][6][7][8] observed substantial fuel penalties resulting from increased surface roughness due to biofilms (in the range of 5 lm-1 mm, reviewed in Salta et al 9 ). Being part of a surface, biofilms will also be affected by these forces, and thus, it is imperative to better understand the effect of relevant hydrodynamic flow regimes 10 on the biofilm processes (i.e., bacterial attachment and initial biofilm formation).…”

In the current study, we have developed and fabricated a novel lab-on-a-chip device for the investigation of biofilm responses, such as attachment kinetics and initial biofilm formation, to different hydrodynamic conditions. The microfluidic flow channels are designed using computational fluid dynamic simulations so as to have a pre-defined, homogeneous wall shear stress in the channels, ranging from 0.03 to 4.30 Pa, which are relevant to in-service conditions on a ship hull, as well as other man-made marine platforms. Temporal variations of biofilm formation in the microfluidic device were assessed using time-lapse microscopy, nucleic acid staining, and confocal laser scanning microscopy (CLSM). Differences in attachment kinetics were observed with increasing shear stress, i.e., with increasing shear stress there appeared to be a delay in bacterial attachment, i.e., at 55, 120, 150, and 155 min for 0.03, 0.60, 2.15, and 4.30 Pa, respectively. CLSM confirmed marked variations in colony architecture, i.e.,: (i) lower shear stresses resulted in biofilms with distinctive morphologies mainly characterised by mushroom-like structures, interstitial channels, and internal voids, and (ii) for the higher shear stresses compact clusters with large interspaces between them were formed. The key advantage of the developed microfluidic device is the combination of three architectural features in one device, i.e., an open-system design, channel replication, and multiple fully developed shear stresses.

“…Perhaps the most thoroughly studied aspect of B. improvisus settlement behaviour is the response of cyprids to surface topography (Andersson et al 1999, Berntsson et al 2000a2000b;Berntsson et al 2004). Many surface features used in antifouling research have been designed to be biomimetic, inspired by the naturally occurring external structures of foulingfree organisms (Salta et al 2010;Scardino & de Nys 2011). Such structures are reproduced as 3-dimensional patterned surfaces fabricated from synthetic polymers (e.g.…”

In conclusion, it is demonstrated that despite previous suggestions to the contrary, these two species of barnacle show similar preferences in response to surface free energy; they also respond similarly to charge. These findings have positive implications for the development of novel antifouling coatings and support the importance of consistency in substrate choice for assays designed to compare surface preferences of fouling organisms.
