“…Particularly worrisome in anthropogenic habitats is S. woodiana , given their widespread distribution and because this species may reproduce continuously throughout the year (Labecka & Domagala, 2018), might even be many times more fecund compared to the native unionids (Labecka & Czarnoleski, 2019) and the presence of its glochidia on fish hosts can limit the metamorphosis of the co‐occurring larvae of native unionid species (Donrovich et al, 2017). Some non‐native invasive bivalves have even been shown to ingest and kill glochidia of native mussels by filtration (Modesto et al, 2019), which would be expected to be exacerbated in restricted anthropogenic habitats with low volumes of water (e.g. irrigation canals, small artificial ponds).…”

Anthropogenic freshwater habitats may provide undervalued prospects for long‐term conservation as part of species conservation planning. This fundamental, but overlooked, issue requires attention considering the pace that humans have been altering natural freshwater ecosystems and the accelerated levels of biodiversity decline in recent decades. We compiled 709 records of freshwater mussels (Bivalvia, Unionida) inhabiting a broad variety of anthropogenic habitat types (from small ponds to large reservoirs and canals) and reviewed their importance as refuges for this faunal group. Most records came from Europe and North America, with a clear dominance of canals and reservoirs. The dataset covered 228 species, including 34 threatened species on the IUCN Red List. We discuss the conservation importance and provide guidance on how these anthropogenic habitats could be managed to provide optimal conservation value to freshwater mussels. This review also shows that some of these habitats may function as ecological traps owing to conflicting management practices or because they act as a sink for some populations. Therefore, anthropogenic habitats should not be seen as a panacea to resolve conservation problems. More information is necessary to better understand the trade‐offs between human use and the conservation of freshwater mussels (and other biota) within anthropogenic habitats, given the low number of quantitative studies and the strong biogeographic knowledge bias that persists.

“…In addition, when considering ecosystem functions, some freshwater bivalves can be ranked among the world's most problematic biological invaders. For example, recent invasions of the zebra mussel D. polymorpha and Asian clam Corbicula fluminea (Müller, 1774) have altered entire aquatic ecosystems by their filtration and burrowing activities, and they have severely affected native bivalve communities by altering bottom habitats and competing for resources (Karatayev et al, 1997;Strayer et al, 1998;Ward and Ricciardi, 2007;Sousa et al, 2009;Higgins and Vander Zanden, 2010;Ferreira-Rodriguez et al, 2018;Modesto et al, 2019).…”

Parasites in sympatric populations of native and invasive freshwater bivalves

et al. 2020

An increasing threat to local, native freshwater mussels (Unionida)-an ecologically important but globally alarmingly declining groupis the invasion by exotic bivalves. The Enemy Release Hypothesis predicts that introduced species should benefit from enemy-mediated competition because they are less likely to be harmed by natural enemies, such as parasites, than their native competitors. We investigated within-site differences in parasitism between sympatric native (tot. five spp.) and invasive (tot. three spp.) bivalves in eight northern European waterbodies, which harboured totally 15 parasite taxa. In paired comparisons using within-site averages, the mean number of parasite species in the native bivalves was 2.3 times higher, and the sum of parasite prevalences 2.4 times higher, than in the invasive bivalves. This may lead to enemy-mediated competitive release of invaders and contribute to the success of invasive freshwater bivalves, in general. However, while the invasive clam Corbicula fluminea was completely free from parasites, parasite parameters of the other invader, Sinanodonta woodiana, were relatively high, indicating that the role of parasites can be invader-specific and urges further research. Understanding the factors affecting success of freshwater bivalve invasions, such as parasitism, can aid invasion

“…Corbicula fluminea presence can exacerbate the pressure on U. delphinus by competing for food [21,38] and reducing available habitats for juvenile unionids. Suspension and deposit feeding negatively impact unionid recruitment, and the ingestion of unionids sperm, glochidia and juveniles may contribute to population declines [9,20]. Also, the introduction of new parasites and diseases [39], and increased ammonia toxicity as a result of massive C. fluminea die-offs, especially in the summer, may also increase native bivalves' mortality [40].…”

Patterns of Distribution of Bivalve Populations in a Mediterranean Temporary River

et al. 2020

In the south of the Iberian Peninsula, many rivers are intermittent, a state most likely to be exacerbated by climate change, strongly affecting river biota. An additional challenge for native biota in this area is the arrival of new species, frequently aided by humans, and bivalves are particularly at risk. Here we assessed whether the native (Unio delphinus) and invasive (Corbicula fluminea) bivalves differed in habitat use. To address this question, we sampled populations of both species in six isolated permanent pools in the same river during summer in three consecutive years. U. delphinus occurred in all pools, while C. fluminea occurred only in the two most downstream pools. U. delphinus, but not C. fluminea, was found preferentially in patches under riparian vegetation cover. Both species were found in similar sediment types (coarse and fine gravel respectively). Although U. delphinus was present in all pools, recruitment was detected only in 2016, in one pool. We concluded that both species have the potential to compete for space, but a well-developed riparian vegetation cover may provide U. delphinus some advantage against C. fluminea.
