“…Biological invasions are usually registered when the invasive species has already established itself (Belz et al, 2012). Santos et al (2012) stated that after the invasion of C. fluminea and other non-native species of molluscs in several Brazilian hydrographical basins, a drastic reduction of native benthonic mollusc populations incurred.…”

Corbicula fluminea is an invasive bivalve responsible for several environmental and financial problems around the globe. Despite the invasive potential of this species, it suffers certain restrictions in lentic environments due to natural phenomena that significantly affect its population structure (e.g. water column fluctuation and sunlight exposure). The present study addresses how temporal decline of the water level in a Neotropical reservoir and exposure to sunlight affect the population structure of C. fluminea. Samplings were carried out twice in the reservoir of Furnas Hydroelectric Power Station (HPS) (Minas Gerais, Brazil), in 2011 and 2012. Population density, spatial distribution and mean shell length of C. fluminea were estimated for each year after sampling in 51 quadrats (0.0625m 2 ) placed on three transects at different distances along the reservoir margins (0, 10 and 20 m from a fixed-point). We observed a predominance of C. fluminea in both years, with a simultaneous gradual decrease in density and richness of native species in the sampling area. Significant differences in density of C. fluminea were registered at different distances from the margin, and are related to the temporal variability of physical conditions of the sediment and water in these environments. We also registered a trend toward an increase in the density and aggregation of C. fluminea as we moved away from the margin, due to the greater stability of these areas (>10 m). The mean shell length of C. fluminea showed significant difference between the distinct distances from the margin and during the years, as well as the interaction of these factors (Distances vs.Years). These results were associated with the reproductive and invasive capacity of this species. This study reveals that these temporal events (especially water column fluctuation) may cause alterations in density, spatial distribution and mean shell length of C. fluminea and the composition of the native malacofauna in Neotropical lentic environments.Keywords: non-native species, desiccation, water column levels, ecological aspects, Furnas HPS reservoir. Como a flutuação dos níveis da água afetam as populações do bivalve invasorCorbicula fluminea (Müller, 1774) em um reservatório neotropical? ResumoCorbicula fluminea é um bivalve invasor, responsável por inúmeros problemas ambientais e econômicos ao redor do mundo. Apesar de sua capacidade de invasão, a espécie sofre certas restrições devido a fenômenos naturais em ambientes lênticos, afetando significativamente sua estrutura populacional (e.g. flutuação do nível da água e a exposição à luz solar). O presente trabalho avaliou como o decréscimo temporal do nível da água de um reservatório neotropical e a exposição solar, afeta a estrutura populacional de C. fluminea. Duas amostragens foram realizadas no reservatório da Usina Hidrelétrica (UHE) de Furnas (Minas Gerais, Brasil), em 2011 e 2012. A densidade populacional, o comprimento médio e a distribuição espacial da espécie para cada ano foram estimados após ...

“…It tolerates a wide range of water temperatures (Lucy et al, 2012) and prefers sand and silt sediments with higher organic matter content (Sousa et al, 2008a). The occurrence of pelagic and benthic life stages enables C. fluminea to spread over long distances by ballast water transport in boats (Paunović et al, 2007;Bódis et al, 2012), by currents, and locally by diffusion due to sand extraction (Belz et al, 2012). Passive transport by aquatic birds between water bodies was also observed (Darrigran, 2002;McMahon, 2002).…”

Please cite this article in press as: Gama, M., et al., Predicting global habitat suitability for Corbicula fluminea using species distribution models: The importance of different environmental datasets. Ecol. Model. (2015), http://dx. a b s t r a c tNiche-based models (NBMs) are increasingly being used to predict the biological distribution of species, as well as the importance of different environmental variables on their habitat adequability. Here, we investigate the reliability of these models in predicting habitat suitability for Corbicula fluminea, an important freshwater bivalve invasive species. In order to determine the influence of topographic vs. climatic variables, three datasets were used: (1) CorbiculaTOPO with topographic variables (altitude, slope and a compound topographical index); (2) CorbiculaMIX, combining climatic (annual mean temperature, mean temperature of warmest quarter, mean temperature of coldest quarter and annual precipitation) and topographic variables and (3) CorbiculaCLIM with only the climatic variables. Nine different types of models, implemented in BIOMOD2, were used and an ensemble of NBMs was built. We aimed to know how climatic suitability for these invaders changes when using different datasets of environmental variables; if the predictive reliability is similar between datasets; and which environmental variables better explain habitat adequability. Model performance was very similar between CorbiculaMIX and Corbicula-CLIM. CorbiculaTOPO was the dataset with the least accurate predictions. Mean temperature of the coldest quarter and altitude were the variables that influenced C. fluminea distribution the most. The use of an ensemble of predictions allowed us to clearly identify areas with potential to be invaded by the bivalve, in which records are not yet detected. This information can be used in management, to implement measures to delay or prevent invasions, as well as for the identification of the environmental variables that favor that invasive potential.

“…However, most studies do not examine endozoochorous dispersal and, therefore, do not attempt to assess the survival and viability of intact specimens (if any) found within retrieved gut or faecal samples. Equally, a variety of freshwater mollusca, such as pea clams (Sphaeriidae), valve snails (Valvatidae), pond snails (Lymnaeidae) and mussels (Mytilidae), have been shown to survive gut passage through different fish and waterbird species, albeit to various extents (Mackie, 1979;Brown, 2007;Belz et al, 2012;van Leeuwen et al, 2012).…”

-Vectors that underpin the natural dispersal of invasive alien species are frequently unknown. In particular, the passive dispersal (zoochory) of one organism (or propagule) by another, usually more mobile animal, remains poorly understood. Field observations of the adherence of invasive freshwater bivalves to other organisms have prompted us to assess the importance of zoochory in the spread of three prolific invaders: zebra mussel Dreissena polymorpha; quagga mussel Dreissena bugensis; and Asian clam Corbicula fluminea. An extensive, systematic search of the literature was conducted across multiple on-line scientific databases using various search terms and associated synonyms. In total, only five publications fully satisfied the search criteria. It appears that some fish species can internally transport viable adult D. polymorpha and C. fluminea specimens. Additionally, literature indicates that veligers and juvenile D. polymorpha can adhere to the external surfaces of waterbirds. Overall, literature suggests that zoochorous dispersal of invasive bivalves is possible, but likely a rare occurrence. However, even the establishment of a few individuals (or a single self-fertilising C. fluminea specimen) can, over-time, result in a substantial population. Here, we highlight knowledge gaps, identify realistic opportunities for data collection, and suggest management protocols to mitigate the spread of invasive alien species.Keywords: ectozoochory / endozoochory / freshwater ecosystems / ichthyochory / invasive alien / secondary spread Résumé -Zoochorie de bivalves d'eau douce ; un vecteur négligé dans les invasions biologiques ?Les vecteurs qui sous-tendent la dispersion naturelle des espèces exotiques envahissantes sont souvent inconnus. En particulier, la dispersion passive (zoochorie) d'un organisme (ou propagule) par un autre, habituellement plus mobile, reste mal comprise. Les observations sur le terrain de l'adhésion des bivalves d'eau douce envahissants à d'autres organismes nous ont incité à évaluer l'importance de la zoochorie dans la propagation de trois envahisseurs prolifiques : la moule zébrée Dreissena polymorpha ; Moule Quagga Dreissena bugensis ; et la palourde asiatique Corbicula fluminea. Une recherche approfondie et systématique de la littérature a été menée dans de multiples bases de données scientifiques en ligne utilisant différents termes de recherche et synonymes associés. Au total, seulement cinq publications ont pleinement satisfait les critères de recherche. Il semble que certaines espèces de poissons puissent transporter intérieurement des spécimens adultes viables de D. polymorpha et C. fluminea. En outre, la littérature indique que les véligères et les D. polymorpha juvéniles peuvent adhérer aux surfaces externes des oiseaux d'eau. Dans l'ensemble, la littérature suggère que la dispersion par zoochorie des bivalves invasifs est possible, mais probablement une occurrence rare. Cependant, même l'établissement de quelques individus (ou un seul spécimen autofécondant de C. flumin...
