“…To assess the colonisation and recruitment ability of L. baconi in artificial substrates, three-dimensionally folded plastic extendable meshes (30 x 50 cm, and 50 ml volume) were randomly placed in each marina (three replicates per marina) submerged at a depth of 1 m. These collectors can recruit a high abundance and diversity of species, including NIS, and constitute a standardised methodology for the study of motile macroinvertebrates in marinas (Ros et al, 2019(Ros et al, , 2020Scribano et al, 2021;Revanales et al, 2022).…”

Studies of non-indigenous species (NIS) often tend to focus on medium and large-sized taxa with potential for remarkable ecological and/or economic impact, whereas the early detection of small invertebrates is often delayed due to taxonomic challenge, lack of consistent, standardised monitoring efforts and limited funding. This study represents the first records of the marine amphipod Laticorophium baconi (Shoemaker, 1934) in Morocco, Tunisia, Corsica (France), Italy, Greece, Egypt, Saudi Arabia and New Caledonia (France). Furthermore, it reports an expansion of its known distribution in Portugal (earliest and northernmost record for the country and first record for Macaronesia), Spain (earliest record for Atlantic and Mediterranean European waters), and Australia (first record for Indian Ocean). Recreational boating and commercial shipping, mainly through hull fouling and secondarily ballast waters, are proposed as vectors for introduction and secondary spread of L. baconi. The following traits, analysed during the present study, could contribute to its invasive potential: (i) quick and extensive spread of the species worldwide, (ii) high densities in marinas, harbours, hull fouling and other artificial habitats, including aquaculture facilities and floating debris, (iii) high ability for short-term colonisation of empty artificial niches, (iv) diet based on detritus suggesting an opportunistic feeding behaviour, and (v) population survival during seasonal fluctuations in different regions. Taxonomic expertise and scientific collaboration, based on multidisciplinary networks of experts, are crucial for the early detection, distribution updates, and risk assessment of small and overlooked stowaways in marine environments.

“…In this study, we used plastic collectors based on three-dimensionally folded PVC meshes. Ros et al [14,24] showed the efficacy of this substrate for collecting a high abundance and diversity of peracarid species compared with other methodologies and Scribano et al [25] its suitability for studying their population dynamics. The structural complexity of these collectors simulates the habitat complexity provided by the local fouling basibionts on which epibiont organisms live.…”

“…Eighteen collectors were randomly placed at each marina in April 2017 (54 in total). At each time considered (one month and three months after placement), nine collectors were care-fully retrieved from each marina and their associated macrofauna was sorted, preserved in situ in 70% ethanol and enclosed in plastic pots following the protocol established by Ros et al [24]. Simultaneously with the retrieval of collectors, a complementary sampling focused on the nearest potential source of 'propagules' was conducted to characterize the local pool of caprellid species associated with the marina's fouling community.…”

Despite the fact that stowaway transport is an increasingly common invasion pathway, its key ecological aspects, such as colonization dynamics of potential invaders on human transport vectors, are poorly understood. Considering that marinas may function as stepping-stone habitats for the spread of marine invaders, they provide a unique opportunity for understanding the first steps in the stowaway pathway. One of the dominant groups inhabiting marinas are caprellid crustaceans. These small invertebrates have demonstrated a high potential for introduction and establishment far beyond their distribution range. Here, we analyzed the colonization dynamics of caprellid species inhabiting marinas of Cádiz Bay (Spain) on plastic collectors and discussed their implications on invasion success. We found that collectors largely mirrored the resident caprellid community assemblages after just one month of deployment, showing that caprellid species inhabiting marina structures have a high capacity to colonize new artificial substrates. Moreover, the two non-indigenous species found, Caprella scaura and Paracaprella pusilla, successfully established dense and well-structured populations in the collectors (including all sex/age groups considered). We suggest a potential interplay between colonization ability and stowaway organisms’ invasion success. Furthermore, collectors used are supported as a useful tool in the early detection of non-indigenous species and their monitoring in relation to resident species.
