“…In the period 1800 to 1835, a few records of this species were made in Western Europe (Kickx in Nyst 1835, Oliver 2015. Since then and also recently, M. leucophaeata has dispersed over brackish waters in coastal areas along the European coasts and is nowadays widely spread (Zhulidov et al 2015 and literature therein;Forstr€ om et al 2016). In The Netherlands, M. leucophaeata was first recorded near the port of Amsterdam (Amstel) in 1895 (Maitland 1897, Scholten 1919, Van Benthem Jutting 1943.…”

ConradÕs false mussel (Mytilopsis leucophaeata) is an invasive alien bivalve species causing severe biofouling problems in cooling water systems of power and industrial plants. Settlement, seasonal shell size distribution, and growth of this bivalve species were analyzed in relation to relevant environmental factors, using monitoring data from a brackish canal over a period of 4 y. Salinity at the sampling site ranged from 3.2 to 9.2, water temperature from 4.5°C to 23.9°C, and chlorophyll a content from 2 to 56 mg l -1 . Once a month one short-term exposed panel (1 mo exposed) and one long-term exposed panel (exposed from February 1989 to the month of sampling) were collected. Settled spat and attached mussels were collected monthly from these polyvinylchloride panels and from stones in the littoral zone. The short-term exposed panels were used to determine the period of spat fall. The long-term panels were used to study growth, shell length-frequency distribution, and densities of the mussel population after settlement. To study maximum age, M. leucophaeata were kept in cages in the canal. The highest recorded settlement was 204,000 individuals/m 2 . The largest mussel had a shell length of 24.0 mm. Three cohorts of shell length (1-5 mm, 5-15 mm and 15-24 mm) could be distinguished. Data on survival of individual mussel size groups in cages indicated a maximum age of 4.5 y. Shell growth was very low in winter time (average growth less than 1 mm/day in the period of November to April). The average growth rate on the stones during the summer periods (3-4 mo) was 89 mm/day. On the panels, a rapid shell growth to an average shell length of 4 mm was recorded in the period of July until November in their first year, followed by a period of hardly any shell growth from December until May, and a subsequently rapid shell growth to an average shell length of 13 mm during the period of May until August in the second year. Individual mussels grew up to 20.9 mm during a 13-mo period. Growth of shells was significantly correlated with water temperature. The minimum threshold temperature for shell growth stops was 9.1°C (9.1°C-10.1°C) based on monthly measurements. Growth started at a minimum temperature of 9.1°C (9.1°C-14.2°C).

“…The estuarine dark false mussel Mytilopsis leucophaeata (Conrad, 1831) is native from the Gulf of Mexico and Atlantic coast of North America, but has invaded several sites in Europe, Asia and America (Kennedy 2011, Forsström et al 2016, Fernandes et al 2018, Lodeiros et al 2019). The few confirmed records for the established non-native populations of M. leucophaeata in Brazil are restricted for two coastal systems of the Rio de Janeiro city: Rodrigo de Freitas Lagoon (Rizzo et al 2014, Fernandes et al 2018 and Marapendi Lagoon (Fernandes et al 2020).…”

The invasion record for the estuarine bivalve Mytilopsis leucophaeata in Brazil is in Rio de Janeiro city, including the Rodrigo de Freitas Lagoon, where high densities of this invader were registered. This work aimed to (1) assess the composition and structure of the benthic macrofauna associated with this invader in Rodrigo de Freitas Lagoon, ( 2) analyze the spatiotemporal variation of richness, density and diversity of the associated benthic community, and (3) correlate changes on the density of the associated benthic species with some water quality variables and the density of M. leucophaeata. Clusters of M. leucophaeata were collected monthly (two years) in four sites. Nine taxa associated with M. leucophaeata were found; Heleobia sp. (Gastropoda) and Melita mangrovi (Amphipoda) showed the highest densities. The structure of the benthic macrofauna slightly differed among sampling sites, but not between dry and wet seasons. The water quality parameters, specifi c patterns of each taxon and high densities of M. leucophaeata contribute to variations in density of the associated species. Oscillations in the densities of M. leucophaeata and the native bivalve Brachidontes darwinianus suggest some agonistic relationship between them, such as a competition for space.

“…The latitudinal variation of native occurrence is similar between M. leucophaeata and M. sallei (Δ Lat = 21° and 18°, respectively) but, in the last four decades, both species consolidated and expanded their distributions to non-native areas. Considering our compilation of georeferenced occurrence records for Mytilopsis species, the updated distribution of M. leucophaeata ranges from almost the polar seas of Finland(Forsström et al 2016) to the tropical climate of Brazil(Rizzo et al 2014) (Δ Lat = 83°). In parallel, the updated distribution of M. sallei ranges from the temperate climate of Japan(Otani 2002) to the tropical climate of Fiji Island (Marelli and Gray 1983) (Δ Lat = 53°).…”

False mussels are recognized as the brackish water equivalent of zebra mussels, although the abiotic and habitat conditions that mediate these invaders’ success are barely known. In this context, we aimed to evaluate the native and non-native geographical distribution of Mytilopsis species worldwide and assess biological traits, environmental condition, and habitat associated with false mussels in native and invaded systems. Our hypothesis is that Mytilopsis invasion is driven by species plasticity to environmental conditions and substrate use in brackish systems, where the colonization of non-native populations is favored by great availability of artificial substrates and tolerance to wide ranges of environmental conditions. Besides, this study provides the occurrence range and distribution patterns of Mytilopsis species within their introduced and native areas and tracks the spread of introduced populations worldwide. Considering the five species evaluated, M. leucophaeata and M. sallei are the most widespread, while M. adamsi, M. trautwineana, and M. africana showed more restricted geographic distribution. In the last decades, M. leucophaeata and M. sallei consolidated and expanded their distributions. Environmental conditions were significantly different between native and non-native areas, where Mytilopsis populations presented significantly higher densities. Non-native populations exhibited remarkable plasticity concerning habitat colonization that was more frequent on artificial substrata. Mytilopsis populations presented significant differences on their biological traits, habitat environmental conditions, and substrate use between native and non-native areas. These species seem to adapt to the conditions of invaded systems, changing their preferences, which reflects plasticity and suggests a potential shift of their realized niches.
