Environmental factors restrict the invasion process ofLimnoperna fortunei(Mytilidae) in the Neotropical region: A case study from the Andean tributaries

Abstract: -The golden mussel Limnoperna fortunei was introduced into Argentina in 1991 and has since been spreading through the Plata and Guaı´ba basins at a rate of 240 km.year x1 . To assess their ability to invade the Andean tributaries of the Plata Basin (Pilcomayo, Bermejo and Salado del Norte rivers), their current range was assessed and related to the abiotic parameters of sites where they were present and absent. These data were then compared with their known tolerances to identify possible barriers to invasion.… Show more

“…They also only provide an assessment of risk according to existing knowledge (if incomplete, then precautionary principles are then used) and management decisions are still required over how that risk should be managed (Britton et al 2011a, b). In Brazilian aquaculture and sport fisheries, whilst these risk-based and precautionary approaches are rarely used (Agostinho et al 2005;Darrigran et al 2011), elements can be used in post-introduction phases to help inform future management approaches (Britton et al 2011a). For example, species' assessments can be compared with their economic values to quantify their risks versus benefits.…”

“…Los ensayos realizados en este capítulo, pioneros en la Región Neotropical, permiten inferir un impacto negativo por adhesión de L. fortunei sobre los bivalvos nativos, similares a los observados en Norteamérica y Europa con D. polymorpha y los unionidos nativos, debido a las similitudes ecológicas entre ambas especies invasoras y entre las especies de bivalvos nativos (Boltovskoy et al 2006;Darrigran & Damborenea 2011;Karatayev et al 2007bKaratayev et al , 2010. La adhesión no es el único mecanismo por el que los bivalvos invasores bisados pueden impactar a los bivalvos nativos infaunales se ha observado en el Hemisferio Norte, altas tasas de mortalidad en poblaciones de uniónidos con bajas tasas de fouling por D.…”

“…Asimismo, las densidades que pueden alcanzar sus poblaciones (e.g. un estimado de 45 billones en el Embalse Río Tercero, Córdoba) (Boltovoskoy et al 2009a), podrían disminuir sustancialmente la cantidad de recursos presentes para otros organismos bentónicos (Boltovskoy et al 2009a;Darrigran & Damborenea 2011).…”
