“…However, the ecological performance of these concrete mixes in the medium and long term still requires further investigation (Bone et al, 2022a). Finally, our findings indicate that the surface integrity of concrete might compromise the ecological status of mature communities, therefore, local quarry rock might be a more suitable and sustainable material for blue marine infrastructure than concrete (Firth et al, 2020;Doods et al, 2022;Baxter et al, 2023).…”

“…Most of the previous studies have pointed out that artificial substrates do not act as natural surrogates (Bulleri & Chapman, 2004;Burt et al, 2009) due to differences in material type, substrate complexity, inclination, orientation and wave exposure among others (Hanlon et al, 2018;Evans et al, 2021;Grasselli & Airoldi, 2021;Hartanto et al, 2022). However, few exceptions have evidenced that artificial substrates are not generally ecologically poor (Gacia et al, 2007;López, 2022;Baxter et al, 2023). For instance, artificial rocky substrates from locally quarried stones, as in the Villaricos site, are generally considered beneficial for colonization by marine organisms (Sempere-Valverde et al, 2018;MacArthur et al, 2019).…”

“…Sedano et al (2020) attributed the presence of a significantly higher number of taxa on artificial hard substrates in comparison with the nearest natural rocky shores in some areas of southern Spain to stochastic variability in the distribution of the epifauna assemblages on the artificial structures. However, results varied depending on the site, indicating that local environmental and anthropogenic factors could be more deterministic than substrate type in structuring benthic assemblages (Bulleri, 2005;Cacabelos et al, 2016;Baxter et al, 2023).…”

The aim of this investigation was to assess the differences in terms of α-diversity, species composition and trophic structure between peracarid assemblages inhabiting artificial hard substrates and those present on natural ones at two sites in the Western Mediterranean Sea. In each one, samples were collected from natural and artificial substrates, and the extracted peracarids were identified to the species level. Each sample was characterised by its Total Abundance, Species Richness, and 1-D Simpson, Shannon, Margalef and Equitability indices. A cluster plot based on the Bray-Curtis coefficient was conducted to detect the presence of distinct assemblages. In addition, the proportion of individuals belonging to each feeding guild was studied. The ecological indices revealed that assemblages from the artificial substrates at the Villaricos site showed lower values of diversity, while they were more diverse at the Calpe site. These results indicated that artificial hard substrates were not always inadequate ground for these animals. The species composition differed between artificial and natural hard substrates in the two studied sites and the trophic structure was also modified, although, in this case, the changes were similar in both sites. However, the difference in both respects seems to be higher between sites than between substrates, evidencing the importance of local scale processes.

“…Globally, the nearshore environment has been heavily modified. Although hard‐structure‐associated marine species may benefit from some types of human developments (e.g., bivalves and rocky‐bottom fishes inhabiting platforms, rock walls, and boat moorings; Bradley et al., 2023; Waltham & Sheaves, 2015), impacts on structure‐negative species, including mobile and roving shallow‐water species (e.g., sand inhabiting taxa), are easily overlooked and can be challenging to quantify (Baxter et al., 2023; Costa‐Pierce, 2022). Furthermore, marine animal movement patterns and migrations along coastal routes can be critical for foraging, reproduction, and seeking refuge in many marine species, particularly large, highly mobile taxa.…”

Although human‐made barriers to animal movement are ubiquitous across many types of ecosystems, the science behind these barriers and how to ameliorate their effects lags far behind in marine environments compared with terrestrial and freshwater realms. Using juvenile sawfish in an Australian nursery habitat as a model system, we aimed to assess the effects of a major anthropogenic development on the movement behavior of coastal species. We compared catch rates and movement behavior (via acoustic telemetry) of juvenile green sawfish (Pristis zijsron) before and after a major coastal structure was built in an important nursery habitat. Acoustic tracking and catch data showed that the development did not affect levels of sawfish recruitment in the nursery, but it did constrain movements of juveniles moving throughout the nursery, demonstrating the reluctance of shoreline‐associated species to travel around large or unfamiliar coastal structures. Given the current lack of information on human‐made movement barriers in the marine environment, these findings highlight the need for further research in this area, and we propose the development of and experimentation with marine animal crossings as an important area of emerging research.
