“…Marinas form dense networks along the coasts and host diverse and abundant NIS taxa (e.g., sessile NIS in marinas of the Celtic Sea, Bishop, Wood, Lévêque, Yunnie, & Viard, 2015; Minchin, 2007b). As such, they are putatively an important source of propagules for the colonization of neighbouring natural habitats (Bulleri & Chapman, 2010; Glasby, Connell, Holloway, & Hewitt, 2007). Similar spillover effects can occur from farmed NIS, as exemplified in the well‐studied Pacific oyster Crassostrea gigas (or Magallana gigas according to the World Register of Marine Species, Costello et al., 2013) in the NE Atlantic (Troost, 2010), or the Atlantic salmon Salmo salar in the NE Pacific (Fisher, Volpe, & Fisher, 2014; Glover et al., 2017).…”

Ports and farms are well‐known primary introduction hot spots for marine non‐indigenous species (NIS). The extent to which these anthropogenic habitats are sustainable sources of propagules and influence the evolution of NIS in natural habitats was examined in the edible seaweed Undaria pinnatifida, native to Asia and introduced to Europe in the 1970s. Following its deliberate introduction 40 years ago along the French coast of the English Channel, this kelp is now found in three contrasting habitat types: farms, marinas and natural rocky reefs. In the light of the continuous spread of this NIS, it is imperative to better understand the processes behind its sustainable establishment in the wild. In addition, developing effective management plans to curtail the spread of U. pinnatifida requires determining how the three types of populations interact with one another. In addition to an analysis using microsatellite markers, we developed, for the first time in a kelp, a ddRAD‐sequencing technique to genotype 738 individuals sampled in 11 rocky reefs, 12 marinas, and two farms located along ca. 1,000 km of coastline. As expected, the RAD‐seq panel showed more power than the microsatellite panel for identifying fine‐grained patterns. However, both panels demonstrated habitat‐specific properties of the study populations. In particular, farms displayed very low genetic diversity and no inbreeding conversely to populations in marinas and natural rocky reefs. In addition, strong, but chaotic regional genetic structure, was revealed, consistent with human‐mediated dispersal (e.g., leisure boating). We also uncovered a tight relationship between populations in rocky reefs and those in nearby marinas, but not with nearby farms, suggesting spillover from marinas into the wild. At last, a temporal survey spanning 20 generations showed that wild populations are now self‐sustaining, albeit there was no evidence for local adaptation to any of the three habitats. These findings highlight that limiting the spread of U. pinnatifida requires efficient management policies that also target marinas.

“…Borja et al, 2000;Rosenberg et al, 2004;Dauvin and Rullet, 2007) while hard-substrate depending benthos has been largely neglected. This is surprising in the light of the fact that the fauna on hard substrates is usually more diverse (Bustamante et al, 2007), because artificial hard-substrate habitats are characterized by reduced predation and competition due to the ample availability of space (Connell, 2001;Airoldi et al, 2005;Bulleri and Airoldi, 2005;Glasby et al, 2007;Reise et al, 2006).…”

“…The presence of hard-bottom fauna on artificial substrates can influence the established community composition on adjacent soft substrates (Davis et al, 1982;Grant et al, 1995;Krone et al, 2013;Seitz et al, 2006). When nonindigenous species (NIS) occur on artificial structures (Ruiz et al, 2009;Glasby et al, 2007;Tyrrell and Byers, 2007;Wasson et al, 2005) these substrates may serve as stepping stones for invasive alien species (Apte et al, 2000;Wilhelmsson and Malm, 2008). Commercial ports and recreational marinas therefore provide the first habitats in a colonization corridor for introduced species (Floerl and Inglis, 2005;Bulleri and Airoldi, 2005).…”

“…Despite extensive studies of artificial substrates in Australian estuaries and in European and American coastal waters (see papers on seawalls, pilings and pontoons by Chapman, 2006;Dafforn et al, 2012;Firth et al, 2014;Glasby et al, 2007;Perkol-Finkel et al, 2012;Pister, 2009;Wasson et al, 2005;etc. ), studies on fouling communities on artificial substrates in the Wadden Sea estuaries are still lacking.…”

a b s t r a c tArtificial substrates are omnipresent today in most estuaries mostly in form of massive rip-rap used for groynes and jetties. In the Weser estuary, Germany, 60% of the shoreline is covered with such artificial substrates while, natural rocky substrate is lacking, as in all Wadden Sea estuaries. This large quantity of artificial substrates may be colonized by a benthic hard-substrate community which differs from the local natural soft-substrate assemblage. In this study we examined species compositions, abundances, biomass, and numbers of species of subtidal benthic communities on groynes and in the natural habitat, the sediment, along the salinity gradient of the Weser estuary. Species composition changed on both substrates significantly with salinity and was also significantly different between the substrates. In a comparison with the sediment, the groynes did not provide any benefit for non-indigenous nor for endangered species in terms of abundance, biomass, and number of species, but represent habitats with higher total abundances and biomass; though some non-indigenous species even occurred exclusively on groynes. In particular, groynes supported filter-feeding organisms which play an important role by linking benthic and pelagic food webs. The dominance of the suspension feeders affects crucial estuarine ecosystem services and may have important implications for the estuarine management by altering the estuarine ecological quality status. Hence, artificial substrates should be considered in future conservation planning and in ecological quality monitoring of the benthic fauna according to the European Water Framework Directive.

“…Patterns of species recruitment to seawalls also tend to differ from that on natural shores (Bulleri, 2005). In addition, artificial structures can also facilitate the colonisation and spread of non-indigenous species (Bulleri and Airoldi, 2005;Glasby et al, 2007), acting as stepping-stones. Thus, sea defence structures seem to act as functional different habitats.…”

a b s t r a c tIt is widely recognised that coastal-defence structures generally affect the structure of the assemblages they support, yet their impact on adjacent systems has been largely ignored. Breakwaters modify the nearby physical environment (e.g. wave action) suggesting a local impact on biological parameters. In the present study, an ACI (After-Control-Impact) design was used to test the general hypothesis that the artificial sheltering of an exposed coast has a strong effect on the structure and functioning of adjacent systems. The effects of a reduction in hydrodynamics were clear for a number of taxa and included the replacement of barnacles, limpets and frondose algae by an increasing cover of ephemeral algae. These effects were evident both at early and late successional stages. Results suggest that the artificial sheltering of naturally exposed coasts can have a strong impact promoting a shift from consumer-to producer-dominated communities, which has important ecological and energetic consequences for the ecosystem.
