“…The physiological tolerance and distribution potentials of invasive molluscs are underestimated when taking chronic tolerance values as indicators of their ability to withstand saline waters. Indeed, judging from previous studies (Angonesi et al 2008; Barbosa and Melo 2009) and our own results at constant salinity concentrations (Fig. 4a), L. fortunei should be unable to maintain a viable population in mixohaline habitats where it actually occurs (Fig.…”

“…Além de observações na natureza, pesquisas de laboratório avaliaram a influência da variação da salinidade na sobrevivência de L. fortunei. Entre estas, podem ser destacadas as realizadas tanto no continente asiático (Deaton et al 1989) como na América do Sul ( Angonesi et al 2008). Esta espécie é capaz de suportar valores menores do que 3 ups, 80% dos exemplares expostos a salinidade 7 ups morrem em 3 semanas e 84% dos expostos a 11 ups morrem em uma semana (Deaton et al 1989).…”

“…O mexilhão dourado pode sobreviver (90%) em condições de choque quando submetidos a águas com salinidade 2 ups por períodos de no mínimo 10 dias. Em testes de choque com salinidade 4 e 6 ups esta espécie mostrou 20% de sobrevivência por período de 10 dias (Angonesi et al 2008).…”

“…Pesquisas de laboratório sobre a influência da variação de salinidade na sobrevivência de L. fortunei foram desenvolvidas por Deaton et al (1989) e Angonesi et al (2008). Além destas pesquisas, estudos em ambientes costeiros relacionados à presença e distribuição de L. fortunei relatam que, entre uma série de variáveis ambientais (temperatura, oxigênio dissolvido, pH), a salinidade pode ser considerada um fator limitante à disseminação da espécie (Darrigran 1995, Darrigran & Pastorino 1995, Ricciardi 1998, Darrigran 2002, Capítoli & Bemvenuti 2004, Brugnoli et al 2005, Piedras et al 2007.…”

Limnoperna fortunei (mexilhão dourado), um bivalve de água doce do sudeste da Ásia, invadiu o sul da América do Sul em torno de 1991. Dados de ocorrência da espécie e salinidade ao longo do ano foram usados para predizer o potencial de sobrevivência de L. fortunei na Laguna dos Patos, RS. Um modelo preditivo foi construído usando regressão logística. Obtivemos na literatura 26 registros de presença (vivo, morto) de L. fortunei e valores de salinidade medidos em cada um destes registros na Laguna dos Patos entre o período de 2001 a 2004. Registros adicionais de salinidade foram utilizados para interpolar os valores por toda a Laguna dos Patos. Sobrevivência de L. fortunei diminui quando a salinidade aumenta na Laguna dos Patos. Os mapas de distribuição predita das áreas favoráveis à sobrevivência de L. fortunei indicam que durante os períodos de baixas salinidades as regiões límnica, pré-límnica e estuarina da laguna mostraram-se favoráveis para a sobrevivência da espécie. Nos períodos de altas salinidades (verão) a sobrevivência do molusco é favorável apenas na região límnica e na região pré-límnica. Estes resultados sugerem que o controle mais efetivo desta espécie deve ser feito durante o verão.

“…It is also highly dynamic, with both regular fluctuations due to tides, as well as human alterations and extreme events. Salinity appears to be particularly important in controlling the distribution of the golden mussel Limnoperna fortunei in estuaries (Angonesi et al, 2008). Corbicula sp., on the other hand, appear to be tolerant to a wide range of salinities in estuaries, with a higher tolerance of 20 ppt during cooler winter months than during summertime conditions (∼15 ppt) (Ferreira-Rodríguez and Pardo, 2016), though salinity fluctuations in the lower portion of the Minho estuary were hypothesized as a potential contributor to a mortality event during an extreme heat wave and drought in Portugal (Ilarri et al, 2011).…”

Mass mortality events, the rapid, catastrophic die-off of organisms, have recently been recognized as important events in controlling population size, but are difficult to quantify given their infrequency. These events can lead to large inputs of animal carcasses into aquatic ecosystems, which can have ecosystem scale impacts. Invasive freshwater bivalves such as the Asian clam Corbicula fluminea, the zebra mussel Dreissena polymorpha, the golden mussel Limnoperna fortunei, and the Chinese pond mussel Sinanodonta woodiana can attain high densities and biomass and play important roles in aquatic ecosystems through filtration, bioturbation, and excretion. Invasive bivalve species can best be described as R-selected species and appear not to have the same tolerance to abiotic stressors as native species, causing them to be prone to mass mortality events in their invasive range. In contrast to their ecological effects while alive, the frequency and impacts of mass mortality events of invasive freshwater bivalves are not well-understood. Here we review the causes and impacts of mass mortality events, as well as identify important questions for future research. Extreme abiotic conditions, including both drought and flooding, as well as high and low temperatures were the primary drivers of mass mortality events. Short-term impacts of mass mortality events include large pulses of nitrogen and increased oxygen stress due to large amounts of soft tissue decomposition, while shells can impact habitat availability and nutrient cycling for decades. Impacts on biological communities (bacteria, fungi, and macroinvertebrates) are less studied but some examples exist concerning C. fluminea. Better documentation of mass mortality events, particularly their magnitude and frequency, is needed to fully understand the impacts invasive bivalve species have on ecosystems, especially as climate change may make mass mortality events more frequent and/or have a larger magnitude.
