“…Subsequent field studies (Rakocinski et al 1996, Peterson et al 2000) and reviews (Hackney et al 1996, Greene 2002 have reinforced this view. Augmenting the coarse fraction of sediments and shell hash on the beach can have similarly large effects on the infauna, especially on burrowing bivalves (McLachlan 1996, Peterson et al 2006, 2014.…”

“…Consequently, choosing the timing of deposition relative to seasonal recruitment may be an important management decision if one of these processes proves to have generally larger or more wide-spread impacts. Where turbidity may interfere with the ability of visually orienting fishes to detect prey, timing deposition projects to avoid seasons of intense fish predation on sandy beach benthos would be desirable (Peterson et al 2006, Manning et al 2013. Whether the fill sediments are finer or coarser than original sediments may also affect the ability of or ganisms to burrow and feed (Manning et al 2013, Van Tomme et al 2013, Viola et al 2013) and influence the lifetime of fill placement (Warrick 2013).…”

“…This study showed that the use of geosynthetic containers in coastal defence, even though less impacting than building seawalls or groynes, has some long-term effects making these interventions not fully comparable to soft-engineering procedures, generating short-term pulse disturbance (Leewis et al, 2012;Peterson et al, 2006). In this case, the main issue seems to have been the partial removal of the sandy coverage after the dune-recovery, preventing the beach animals to burrow into the sand.…”

“…Recent examples of successful application of geotextile tubes come from the coastal zones of USA (Harris and Sample, 2009), Australia (Jackson et al, 2004) and the Republic of Korea (Shin and Oh, 2007), where positive outcomes were obtained in terms of coastal protection. However, very little is known on the effects of dune recovery with geotextiles on biotic communities, if compared to the several studies on the ecological impacts of both beach nourishments (reviewed in Goldberg, 1988;Peterson et al, 2006;Speybroeck et al, 2006) and hard-engineering interventions (Bertasi et al, 2007;Dugan et al, 2008;Martin et al, 2005;Sobocinski, 2003). Negative nourishing effects were observed at the population, community and ecosystem levels on all the biotic components Fanini et al, 2009;Speybroeck et al, 2006).…”

a b s t r a c tIn the last decades the increasing urban development on coastal areas have produced extensive modifications on shores all over the world, making critical the active management of pressures on sandy beaches. The use of engineering solutions to counteract beach erosion has been significantly increasing; the ecological indicators used to monitor these interventions generally focus on short-and medium-term effects, while little is known on their effectiveness on long-term temporal scales. The following ecological indicators have been tested in the present study: (a) macrofaunal community abundance and diversity and (b) orientation behaviour of Talitrus saltator, a talitrid amphipod widespread on Mediterranean and European Atlantic sandy beaches. Two sites were considered on a sandy beach of the Portuguese Atlantic coast, one located in front of a natural dune and the other at about 500 m of distance, where the dune had been rebuilt between 2000 and 2008 using geotextile tubes. In 2011 and 2012, macrofauna sampling and orientation experiments on T. saltator were performed at both sites in spring and autumn; contemporaneously the main environmental variables were registered. Macrofaunal data were analysed through multivariate statistical tests, and for the orientation distributions the circular statistics were calculated and multivariate analyses for angular data were performed. Geotextiles appeared to be successful in stabilising the recovered dunes; accordingly, the diversity of the macrofaunal communities and the orientation performances of T. saltator showed no differences between the altered and control sites. Significant reductions were nevertheless observed in the artificial-dune site regarding the abundance of T. saltator and, to a lesser extent, macrofaunal densities, likely ascribable to the presence of geotextiles instead of a vegetated natural dune, preventing invertebrates to burrow into the sand. These results, complementing a more comprehensive study on these two sites, indicate the abundance of T. saltator as the best indicator to follow long-term effects of this kind of soft-engineering intervention. The use of this bioindicator may be recommended for the late phases of monitoring procedures in dune-recovery processes.

“…Nourishment smothers natural communities of beach-dwelling invertebrates, and, by introducing high volumes suspended sediment to the nearshore zone, impairs the feeding effectiveness of fish that forage and hunt in the surf zone [141][142][143]. Sand size, texture, and colour can vary depending on its source, and where nourished beaches are also nesting habitats for sea turtles, characteristics of nourishment sand can affect nesting success, clutch survival, and hatching sex distributions [144][145][146][147].…”

Toward a Global Classification of Coastal Anthromes

Given incontrovertible evidence that humans are the most powerful agents of environmental change on the planet, research has begun to acknowledge and integrate human presence and activity into updated descriptions of the world's biomes as "anthromes". Thus far, a classification system for anthromes is limited to the terrestrial biosphere. Here, I present a case for the consideration and validity of coastal anthromes. Every coastal environment on Earth is subject to direct and indirect human modification and disturbance. Despite the legacy, ubiquity, and pervasiveness of human interactions with coastal ecosystems, coastal anthromes still lack formal definition. Following the original argument and framework for terrestrial anthromes, I outline a set of coastal anthrome classifications that dovetail with terrestrial and marine counterparts. Recognising coastal environments as complex and increasingly vulnerable anthropogenic systems is a fundamental step toward understanding their modern dynamics-and, by extension, realising opportunities for and limits to their resilience.
