“…5b, Online Rresource 2). Several impacts on the environment made by this species have been detected in South America (Paschoal et al 2015;Reyna et al 2018), including niche overlap and putative negative effects on native Cyanocyclas spp. (Clavijo and Carranza 2018).…”

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,

“…In order to test long-term responses to the temperature increase, individuals were kept at each temperature for 8 weeks (Figure 2). The 20-30°C interval fits the temperature sensitivity coefficient Q 10 calculation and does not correspond to lethal temperatures for this species (Reyna et al, 2018).…”

“…In recent decades, highly invasive bivalves, such as Limnoperna fortunei ( Dunker 1857), Dreissena polymorpha ( Pallas 1771), Dreissena rostriformis bugensis ( Andrusov 1897), and the Asian clams Corbicula largillierti ( Philippi , 1844), Corbicula fluminalis ( Müller , 1774), and C. fluminea ( Müller , 1774), have invaded wide areas of America and Europe (Boltovskoy, ; Gallardo et al., 2013; Korniushin, 2004; Reyna et al., 2018). These benthic freshwater species reach high densities in short periods of time, altering not only the substrate but also the carbon and energy flux among the components of the invaded system (Karatayev et al., 2007; McMahon, 2002; Sousa, Gutiérrez, & Aldridge, 2009).…”

“…There are clear hydrological differences between this reservoir and the surrounding rivers, especially during summer when the reservoir has mean temperatures of ~27 ± 3°C and the rivers remain ~22 ± 4°C. The high temperatures of the reservoir during summer months are within the natural maximum temperature range described for this species' distribution (Reyna et al, 2018). Nonetheless, the effect of long-term exposure to these temperatures may signify an increase in metabolic rate, with detrimental consequences on behavioral performance, growth, reproduction, and ultimately survival (Hochachka & Somero, 2002).…”

“…However, although C. largillierti has been shown to be a potential invader of a variety of ecosystems (Reyna et al, 2018), there are almost no studies about basic aspects of its biology, reproduction, or physiological traits (Azevêdo et al, 2016;Ituarte, 1984;Martins et al, 2006;Reyna et al, 2013). Filling the gaps of fundamental physiological information on this species is crucial to better understand its invasion capacity, predict the magnitude of its impact, and elaborate suitable management policies (Blackburn et al, 2014).…”

The invasiveness of Corbicula largillierti has been underestimated, but this bivalve is currently receiving more attention. The first study of the distribution of this species along one of the major basins of central Argentina showed that it was completely absent in the major central reservoir, but was present along its tributary and effluent rivers. Ten years later, this discontinuous distribution has not changed, despite the bivalve's high dispersion capacity. The main environmental differences between the reservoir and the rivers are that the former has finer sediment grain size, higher temperatures, and lower oxygen concentration during summer months. This study aimed to evaluate whether one of these factors could be limiting the distribution of C. largillierti. We assessed the metabolic response and burial behavior (under different grain sizes) of C. largillierti over 8 weeks at 30°C against a control condition at 20°C. We also analyzed the oxygen consumption (vO2) as a function of environmental oxygen concentration (pO2) at 25°C, estimating its metabolic regulation capacity (R). This showed the existence of an environmental oxygen concentration threshold (Pt) that could be an indicative of physiological limiting concentrations that compromise species survival and settlement. After 8 weeks at 30°C, the metabolic rate of individuals of C. largillierti increased and their burial behavior was slightly compromised but mostly for coarser sediments. Concerning environmental oxygen availability, C. largillierti is an oxyconformer with a low R (39.9%), a clear pattern of negative regulation, and a low Pt (48.4% air saturation). The lack of any regulation capacity of C. largillierti under environmental oxygen limitations and the extremely low pO2 at the bottom of the reservoir during summer months may explain its failure to colonize and survive there.

Droughts and heat waves are becoming more frequent, persistent, and intense in a global warming context. Although previous studies reported Corbicula mass mortality events associated with the occurrence of extreme summer conditions, knowledge of their effects lags behind ecosystem functioning. The goal of this study was to determine whether summer environmental degradation (droughts, extreme temperatures, and spikes in ammonium concentration) influences the survival and behaviour of native mussels in rivers invaded by Corbicula and, in consequence, their functioning in ecosystems. Unio delphinus mussels were exposed to increasing summer environmental degradation. Water column and pore water samples were collected at six sampling time‐points for nutrient analysis. Environmental conditions, survival and behaviour were monitored at 12‐hour intervals. Mortality risk was greatest under no‐flow conditions, reaching 100% of mortality after 84 ± 22 hours of exposure to anoxic (<2 mg O2 L−1) conditions. At the sub‐lethal level, quiescent conditions impaired filtration activity. In addition, when facing rising temperatures, native mussels buried deeply and vertical movements were depleted. There were significant differences between the water column and the pore water in physicochemical characteristics. Oxygen and nitrate concentration were generally higher in the water column. In contrast, ammonium and phosphate maximum concentrations were measured in the pore water. The results suggest that environmental degradation affects the role of mussels in ecosystem functioning. For instance, prolonged valve closure under poor water quality conditions may have impacts on particle removal from the water column. Furthermore, impairment of vertical movements may reduce nutrient release from sediments. The present study has key implications for water management and for the conservation of mussel populations. For instance, a responsible approach for maintaining ecosystem integrity should include the water needs of freshwater mussels in environmental flow recommendations and the conservation of riparian vegetation corridors to mitigate the effects of increased water temperature in rivers.
