“…offering shelter and refuge within their encrusting calcareous tubes; Floerl et al 2004, Stacho wicz & Byrnes 2006. Within the macrofouling community, interestingly, the 2 small nonindigenous peracaridan species, Monocorophium acherusicum and Ericthonius punctatus, have been recorded as dominant compared to native species, especially in harbour areas and in other Mediterranean areas (Rumbold et al 2016). Hard substrata provided by fish farm components seem to represent the perfect artificial habitat to investigate the settlement of benthic NIS (Maug han 2001, Bowden et al 2006 and are confirmed as NIS hotspots by our re sults.…”

“…Species were categorised into 4 biogeographic groups: Group I (native species), Group II (casual species), Group III (established species) and Group IV (invasive species). The index, based on the percentages of abundance of each group within the community, classified the ecological status of studied area as follows: Rumbold et al 2016); and the other species in Group I (i.e. native species).…”

Understanding the spread and establishment of non-indigenous species (NIS) is one of the primary areas of focus in bioinvasion science and is essential for generating appropriate management strategies in aquaculture. Here we investigated the role of 2 non-indigenous serpulid tube worms (Hydroides elegans and H. dirampha) in shaping the hard substrata communities around a fish farm in the Strait of Sicily over 1 yr (. The mean density values of serpulids were significantly different at each sampling time. The density of serpulids on submerged panels showed a peak in spring (March 2015, after 9 mo) and decreased drastically in summer (June 2015). Hydroides shaped the entire associated macrobenthic community, which showed the highest density in the first month of observations. The lowest density was recorded in proximity to the highest density of serpulids. Margalef's species richness of the associated macrofaunal community peaked at the end of monitoring (summer). Our results will add new insights into the role of aquaculture as a vector and pathway for NIS.

“…Abundances of both species in the port follow a seasonal pattern, characterized by peaks in the summer and early autumn, and low values throughout the cold season. This pattern most probably reflects the effect of the temperature, which is the primary factor modulating the populations of other well established NIS and cryptogenic species in Mar del Plata port, such as the amphipods Monocorophium acherusicum (Costa, 1853) and Ericthonius brasiliesis (Dana, 1853), the isopod S. serratum and the tanaidacean Tanais dulongii (Audouin, 1826) (Kittlein, 1991;Rumbold et al, 2015bRumbold et al, , 2016Rumbold et al, , 2017. Given that hull surveys were conducted during the winter, higher abundances of D. edwardsi and P. sculpta than observed here should be expected during warm months.…”

Two new nonindigenous isopods in the Southwestern Atlantic: Simultaneous assessment of population status and shipping transport vector

The Southwestern Atlantic is often perceived as remote region, yet it is not immune to biological invasions. Patchy information on historical community composition hinders our ability to identify introductions to coastal ecosystems in this region. Hull fouling is an under-managed shipping vector that likely continues to transport large numbers of marine species worldwide. The port of Mar del Plata is a comparatively well-studied shipping and commercial hub that may serve as an observatory to monitor new introductions to the Argentine coast. Following detection of nonindigenous isopods during preliminary port sampling in 2007-2008, we organized regular port surveys aimed at assessing the level of population establishment and evaluated hull fouling as a potential introduction vector in the Port of Mar del Plata. In 2011-2012, we conducted 12 monthly dive surveys of port isopod communities in combination with three opportunistic surveys (two in-water, one in dry-dock) of hull fouling communities attached to a domestic research vessel during consecutive port calls at its base in this port. Replicate biofouling samples from underwater dock structures and the vessel's hull were collected by scraping invertebrates in 20 × 20 cm quadrats (even surfaces) and 1000 cm 3 of biofouling organisms (uneven surfaces). Both in port-and hull-fouling communities, we discovered the presence of the nonindigenous isopods Dynamene edwardsi and Paracerceis sculpta. This report constitutes the first detection of these two global marine invaders in American and Argentine waters, respectively. They likely represent relatively recent introductions to this corner of the world's oceans, yet our data indicate that both species are currently well established in Mar del Plata. These results demonstrate (for the first time in the case of D. edwardsi) the potential for hull fouling to disperse both species, and raise a warning on their potential expansion to other Southwestern Atlantic ports and Antarctica in a near future. Research on the marine communities of the Southwestern Atlantic is pressingly needed to establish pre-invasion communities and detect new introductions. Simultaneous surveillance of ports (invasion hubs) and vessels (vectors) can effectively detect invaders and inform prevention efforts in this region.

“…Bousfield and Hoover (1997) suggested that it most probably originated in the eastern North Atlantic: France, Belgium and England. It has been recorded in Argentina (Albano et al 2013;Schwindt et al 2014, Rumbold et al 2016Nuñez Velazquez et al 2017), Chile (Thiel and Hinojosa 2009), Australia (Chilton 1921;Hayes et al 2005), New Zealand (Chilton 1921), Japan (Irie 1956;Hirayama 1995), South Africa (Barnard 1916), the Pacific coasts of North America (Wasson et al 2001;Ruiz et al 2011), and Black Sea, North Pacific Ocean, Indian Ocean, Eastern and South China Seas (Molnar et al 2008). Other authors have suggested that it is cryptogenic (crypt-, Greek, Kryptos, secret; -genic, Latin, genic, origin), as species that is not demonstrably native or introduced (Carlton 1996) in Brazil (Neves et al 2007;Neves and Rocha 2008), Atlantic Europe (UK to Portugal) (Noël 2011), and the east and northwest coasts of the USA (Ruiz et al 2011).…”

“…The population dynamics of amphipods M. acherusicum and Ericthonius punctatus from Mar del Plata harbour has been done by Rumbold et al (2016). They found that both species showed a seasonal pattern characterised by high densities in warmer months, related to the highest reproductive activity and the increase of recruitment in summer and early autumn, as well as lower densities in the cold season.…”

We report the occurrence of the invasive amphipod Monocorophium acherusicum in Mar del Plata port, Argentina, using morphological and molecular analysis and estimated mean abundance to detect monthly variations of this population. We compared M. acherusicum morphology with that of M. insidiosum and Crassicorophium bonelli, the two most similar locally occurring species, to establish the diagnostic characteristics for the correct identification of them; moreover, we provide some taxonomic notes about others corophiids regionally distributed. M. acherusicum were collected in a subtidal biofouling community and its mean abundance was maximum in summer. In the molecular analysis, the maximumlikelihood tree showed that specimens from Mar del Plata were clustered with M. acherusicum specimens from GenBank and Boldsystems. We support and confirm the species identity in Mar del Plata port using DNA barcoding and with taxonomic methods.
