“…In Tasmania for example, despite the relatively rapid spread of Undaria pinnatifida and its capacity to form a closed canopy in dense stands (Sanderson 1990, Valentine and Johnson 2003, Hewitt et al 2005, its overall effect has arguably been small compared to that of introduced benthic marine animals such as A. amurensis (Ross et al 2003), M. roseus and the European green crab Carcinus maenus (Linn.) (Thresher et al 2003). C. maenus has a voracious appetite for small bivalves including mussels, oysters and cockles, and appears to displace a similarly sized native crab species, Paragapsus gaimardii (Milne Edwards) (Walton et al 2002).…”

In the introduction of this special issue of Botanica Marina, we established the scope of this topic around a series of questions, which also provided a framework for integrating the different contributions and a means of highlighting deficiencies in knowledge and understanding (Johnson and Chapman 2007). In defining challenges for the future and suggesting how those challenges might best be tackled to optimize returns on research investment, it is useful to revisit those questions under four main headings dealing with species introductions per se, the invasion process, consequences of invasions and human responses to the threat and occurrence of invasion.

“…On some occasions, alien species were totally absent from the MPA while present in the broader study area; this was the case for: (1) Mytilus galloprovincialis in the Western Cape of South Africa (Malherbe and Samways, 2014), and (2) Drupa albolabris, Nerita tessellata, Saccostrea cucullata, and Semiricinula tissoti in Moorea, French Polynesia (Ardura et al, 2015). All studies used visual census to estimate the density and/or biomass, or percent cover, or catch rate, or colony size of alien species inside vs. outside MPAs, apart from one that used trapping methods (Thresher et al, 2003). The majority of the alien species (∼70%) have been reported to have negative impacts on native species and habitats in their host environment while few species (25%) were harvested in the study region (Table S1).…”

Marine protected areas (MPAs) have proven to be an effective tool to conserve marine biodiversity and restore ecosystem functioning. Yet, the role of MPAs in providing resilience to global threats, such as biological invasions, is poorly understood. Assessing the effects of MPAs on invasive species is crucial for effective MPA planning and management. We conducted a peer-reviewed literature survey to synthesize all available information on the performance of alien/invasive species in MPAs at a global scale. We also assessed the effects of protection on such species following a meta-analytical approach. We found only 17 studies that were suitable for the qualitative and quantitative synthesis. We included studies that provided data on alien species from both inside and outside MPAs. The largest proportion of the available literature provided data on alien molluscs (40%), followed by algae (28%). Information on the effects of protection on alien/invasive species is available for only 11% of the marine biogeographic provinces; principally, for the Mediterranean and Caribbean Seas. Only four studies provided adequate quantitative data to estimate the effect of protection on the density and biomass of 12 alien species. We found that protection had a significant negative effect on half the species, whereas 33% of the species were positively affected. Our review demonstrates the scarcity of data on this crucial topic. More evidence on various species and taxonomic groups across marine regions is necessary to draw robust conclusions.

“…Similar traps have been used to detect C. maenas in Australian waters (Thresher et al 2003). Traps were weighted with half a fired clay brick and baited with a single frozen 8-15 cm pilchard (Sardinops neopilchardus) housed in a perforated bait-bag of 1.3 cm plastic mesh.…”

“…It has established populations on the Atlantic and Pacific coasts of North America, South America, South Africa, and southern Australia (Carlton and Cohen 2003;Thresher et al 2003). In Australia, C. maenas was first recorded in Port Philip Bay, Victoria, in the late 1800s (Thresher et al 2003).…”

Semi-enclosed coastal water bodies range from permanently open estuaries to lagoons that are periodically isolated from the ocean. The proportion of time these are connected to the ocean may influence biological invasions by determining recruitment opportunities, environmental conditions, and available biogenic habitats. Along the south coast of New South Wales, Australia, we tested whether the abundance and persistence of the nonnative crab, Carcinus maenas, varies among coastal water bodies according to the proportion of time their entrance is open to the ocean. In quarterly sampling over 2 yr in 14 estuaries and lagoons varying in the percentage of time they were closed to the ocean from 0-100% crab presence and abundance was correlated with the proportion of time the entrances were open. Crabs were absent from lagoons with entrances closed to the ocean . 60% of the time and consistently detected in open estuaries. Crab abundance increased with the connectivity of coastal water bodies to the ocean and was influenced by habitat availability. In water bodies where conditions supported mangroves, this habitat contained higher abundances of crabs than seagrass, saltmarsh, oyster habitat, or bare substrate. Entrance morphology initially predicts the likelihood of the crabs' arrival by influencing their population connectivity between estuaries or lagoons and the open coast, and the probability of establishment by influencing abiotic conditions. Entrance morphology may also affect crab abundance by influencing the available habitats. Hence, the geomorphology of semi-enclosed coastal water bodies should be considered when managing marine bioinvasions.
