“…In South America, only one investigation, in the Parana River delta of Argentina (Boltovskoy et al, 1997), found greater C. fluminea abundance than our observations in the CR, whereas eight other South American studies reported abundances below those of the CR, including in the Argentinian lowlands (Reshaid et al, 2017;Reyna et al, 2013), Patagonia (Labaut et al, 2021), and tropical/subtropical areas of Brazil (França et al, 2007;Paschoal et al, 2015;Silveira et al, 2016) (Table 1).…”

The Asian clam, Corbicula fluminea, is an invasive freshwater bivalve that has established populations across the globe and is known to have deleterious effects on natural and human systems. Yet, despite being present in the Columbia River (CR) for nearly a century, little is known about this invader's basic biology and ecology in this large river system. Thus, we undertook a field study to assess its (i) broadscale distribution and abundance, and (ii) associations with habitat characteristics in the lower CR. During 2019-2020, C. fluminea were collected from 27 shore-based stations spanning 481 river kilometers of the lower CR, along with several habitat characteristics (bank slope, temperature, dissolved oxygen, pH, salinity, conductivity, chlorophyll-a concentration, and sediment composition and % organic matter [OM]). C. fluminea abundance ranged from 0 to 430 ind. m −2 . Most sites with abundances >100 ind. m −2 were located downstream of Bonneville Dam, whereas most sites with abundances <100 ind. m −2 were located upstream. Generalized linear models predicting the abundance of C. fluminea indicated significantly positive correlations with water temperature and % sand, and negative correlations with bank slope and sedimentary % OM. We also reviewed the global literature on abundance and habitat associations of C. fluminea and compared this with our own results. Our investigation represents the greatest spatial extent at which C. fluminea has been studied in the CR and our results provide a better understanding of the basic biology and ecology of this global invader, as well as provide natural resource managers with information on habitat conditions favorable for this invasive bivalve within temperate river ecosystems.

“…C. fluminea's population densities of between 133-519 ind/ m 2 in the Limay River were lower than those described for more "successful" populations in northern South America (eg., Rio Grande do Sul, Brazil and Río de La Plata, Argentina), and across the world (Danube, Bulgaria; Mondego, Portugal; New River, United States), which have all recorded values between 900 and 269,000 ind/m 2 (Cherry et al, 1986;Dreher-Mansur and Garces, 1988;Darrigran, 1991;Dreher-Mansur et al, 1994;Franco et al, 2012;Hubenov et al, 2013;Modesto et al, 2013;Reshaid et al, 2017). Competition in this species, therefore, seems to be related more to resources than to space.…”

The invasion of the Asiatic clam Corbicula fluminea in South America has already reached Patagonia. Despite the well-known direct and indirect impacts that this species exerts on fresh-water ecosystems, particularly on benthic communities, few studies have been undertaken on its effect on the composition and structure of aquatic macroinvertebrate assemblages. This study evaluated the effects of the invasion of the Asiatic clam C. fluminea on the aquatic macroinvertebrate assemblages of the Limay River, one of the most important rivers of the arid plateau of Argentinian Patagonia. As this river is currently in the process of being invaded, it was possible to compare invaded and non-invaded sites. Invaded sites displayed a certain homogenization of their constituent species and functional composition. Non-metric multidimensional scaling, similarity analysis and similarity percentages showed negative or positive influence of the presence of this species on the abundance of some taxa, due to competition for resources in this low-productivity Patagonian ecosystem. The deposition of the faeces and pseudo-faeces of C. fluminea enriches the organic content of the sediments. However, its pedal feeding can function as a competitive strategy: by consuming its own deposited organic matter when food is scarce, the amount available to other macroinvertebrates is reduced. This paper is the first contribution on the impact of this invasion on northern Patagonia’s aquatic macroinvertebrate assemblages.

“…On the other hand, in the freshwater environment, Corbicula fluminea (Corbiculidae) or the Asiatic clam, was introduced in South America through the Río de la Plata River between the late 60's and early 70's (Crespo et al 2015), possibly by the release of living specimens brought as food on-board in vessels or through ballast water (Paschoal et al 2013). Currently C. fluminea is distributed from the Colorado River in the northern limit of the Argentinean Patagonia (39°0 1 0 S-64°01 0 W) to Venezuela (10°10 0 S-63°30 0 W) (Cao et al 2017;Reshaid et al 2017) (Fig. 5b, Online Rresource 2).…”

Non-native mollusks throughout South America: emergent patterns in an understudied continent

Non-native species have been introduced at escalating rates during the last decades, mainly due to the dispersion generated by the increasing trade and transport worldwide. Mollusks, the second largest metazoan phylum in terms of species richness, are no exception to this pattern, but, to date, a comprehensive synthesis of non-native mollusk species (NNMS) in South America was not available. For this purpose, an e-discussion group was formed with malacologists and taxonomists from South America, where we exchanged and analyzed bibliography, databases and information about NNMS, providing expert opinion to this assessment. The first list of non-native mollusk species for South America, considering terrestrial, freshwater and marine environments, includes 86 NNMS distributed in 152 ecoregions (terrestrial, freshwater and marine) of the 189 recognized for the South American continent. Information on their native region, vectors, first record for South America and distribution, are also provided. In the analysis of the distribution of the NNMS and the entry points of each species (e.g., ports, cargo and passenger airports, cities) and status of conservation of the ecoregions, four hot spots were recognized: Subtropical-Atlantic,

Variation in the distribution of Corbicula species (Mollusca: Bivalvia: Corbiculidae) after 25 years of its introduction in the Río de la Plata, Argentina

Abstract: ABSTRACT. In 1981, Corbicula fluminea (Müller, 1774) and C. largillierti (Philippi, 1844) were recorded at the Río de la Plata River. During the 1980's, C. largillierti was found on a continuous fringe in the shore of that river, while C. fluminea was only
