“…Most of the interactions observed in this study involved the ophiuroid species Ophiactis savignyi, which is known to be a circumtropical species, a generalist in host choice, with reports of association with different species of algae, coral, bryozoans, ascidians, and sponges (De La Cruz-Francisco et al, 2018;Bueno et al, 2018;Carrera-Parra and Vargas-Hernández, 1996;Gondim et al, 2013). Ophiactis savignyi represents a species complex exotic to the Atlantic Oceanic region (Roy and Sponer, 2002) and highly adapted to the Brazilian coast (Soares et al, 2022). The fissiparous strategy of this species could explain the high density of individuals found in a single sponge here (Topsentia ophiraphidites, 127 individuals; and Dysidea etheria, 42 individuals) and in other studies previously performed (Neves et al, 2007;Gondim et al, 2013;Clavico et al, 2006;McGovern, 2002).…”

“…colonizing AMD rafts in previous studies in the SPSG’s Rapa Nui region ( Rech et al, 2018 ; Rech et al, 2021 ), confirming the relatively high frequency of coral rafting. Several species of the same order (Scleractinia), amongst them invasive Tubastraea spp., are also known from floating AMD ( Hoeksema, Roos & Cadée, 2015 ; Hoeksema, Pedoja & Poprawski, 2018 ; Mantelatto et al, 2020 ; Soares et al, 2022 ).…”

Background Long-distance rafting on anthropogenic marine debris (AMD) is thought to have a significant impact on global marine biogeography and the dispersal of non-indigenous species. Therefore, early identification of arrival sites of AMD and its epibionts is crucial for the prioritization of preventive measures. As accumulation patterns along global coastlines are largely unstudied, we tested if existing oceanographic models and knowledge about upstream sources of litter and epibionts can be used as a simple and cost-efficient approach for predicting probable arrival sites of AMD-rafting biota in coastal zones. Methods Using the Southeast Pacific as a model system, we studied daily accumulation rates, composition, and minimum floating times of AMD with and without epibionts on seven sandy beaches, covering the oceanic environment (Rapa Nui/Easter Island) and three regions (south, centre, north) along the Chilean continental coast, over a minimum of 10 consecutive days, and we contrast our results with predictions from published models. Results Total AMD accumulation rates varied from 56 ± 36 (mean ± standard deviation) to 388 ± 433 items km−1 d−1 and differed strongly between regions, in accordance with local geomorphology and socioeconomic conditions (presence of larger cities and rivers upstream, main economic activities, etc.). Daily accumulation of items with pelagic epibionts (indicators of a pelagic trajectory) ranged from 46 ± 29 (Rapa Nui) to 0.0 items km−1 d−1 (northern continental region). Minimum floating times of rafts, as estimated from the size of pelagic epibionts, were longest in the South Pacific Subtropical Gyre’s (SPSG) centre region, followed by the high-latitude continental region under the influence of the onshore West Wind Drift, and decreased along the continental alongshore upwelling current, towards lower latitudes. Apart from pelagic rafters, a wide range of benthic epibionts, including invasive and cryptogenic species, was found on rafts at the continental beaches. Similarly, we present another record of local benthic corals Pocillopora sp., on Rapa Nui rafts. Discussion Our results agree with the predictions made by recent models based on the prevailing wind and surface current regimes, with high frequencies of long-distance rafting in the oceanic SPSG centre and very low frequencies along the continental coast. These findings confirm the suitability of such models in predicting arrival hotspots of AMD and rafting species. Moreover, storm surges as well as site-related factors seem to influence AMD arrival patterns along the Chilean continental coast and might cause the observed high variability between sampling sites and days. Our results highlight the possible importance of rafting as a vector of along-shore dispersal and range expansions along the SE Pacific continental coast and add to the discussion about its role in benthic species dispersal between South Pacific oceanic islands.

“…Also, recent reports resulting from baseline assessments of benthic marine species in Brazil highlighting areas nearby harbors as hotspots of mNIS and linking these results with major vectors of introduction (Soares et al. 2022 ). Once a reference library is created, it can be used to investigate mNIS characterized worldwide as capable of causing a high degree of damage.…”

Managing marine nonindigenous species (mNIS) is challenging, because marine environments are highly connected, allowing the dispersal of species across large spatial scales, including geopolitical borders. Cross-border inconsistencies in biosecurity management can promote the spread of mNIS across geopolitical borders, and incursions often go unnoticed or unreported. Collaborative surveillance programs can enhance the early detection of mNIS, when response may still be possible, and can foster capacity building around a common threat. Regional or international databases curated for mNIS can inform local monitoring programs and can foster real-time information exchange on mNIS of concern. When combined, local species reference libraries, publicly available mNIS databases, and predictive modeling can facilitate the development of biosecurity programs in regions lacking baseline data. Biosecurity programs should be practical, feasible, cost-effective, mainly focused on prevention and early detection, and be built on the collaboration and coordination of government, nongovernment organizations, stakeholders, and local citizens for a rapid response.
