“…This is likely to be accentuated by bivalve anti‐predator defences not exhibited in these experiments. Both C. fluminea (Chang, Chang, Shih, Liu, & Lee, 2017) and Unionid mussels (Schwalb & Pusch, 2007) bury into substrates, which were not offered here, which serves as an effective anti‐predator defence (Klocker & Strayer, 2004), meaning that the availability of burying mussels as prey items in‐situ is likely to be further reduced. Dreissenid mussels also attach together to form druses as an anti‐predator defence mechanism (Kobak et al, 2010).…”

Predatory, non‐native fauna can influence biodiversity and trophic dynamics in invaded ecosystems. Signal crayfish (Pacifastacus leniusculus) are a highly successful invader, which have altered freshwater benthic communities, including bivalve populations. Bivalves are a keystone freshwater group in global in decline, partly due to invasion by alien bivalve and crayfish species. However, little is known about the predatory impacts of invasive crayfish within co‐occurring native and invasive bivalve populations. Mesocosm predation choice experiments considered relative signal crayfish predation rates between paired native (Anodonta anatina and Unio tumidus) and invasive (Dreissena polymorpha, D. bugensis, and Corbicula fluminea) bivalves, and between paired invasive bivalves. All bivalves were actively predated, but there was no consistent difference in the biomass of invasive versus native bivalves consumed. However, the effects of consumption were consistently different; 18.2% of invasive bivalves were lethally predated, with 100% of surviving individuals remaining undamaged, whereas 1.1% of native bivalves were lethally predated, but 100% of surviving individuals received nonlethal damage in the form of shell chipping, which could reduce long‐term bivalve fitness in natural environments. In experiments considering paired invasive species, D. polymorpha was more resistant to predation when compared to other invasive taxa tested. The majority of field research considering aquatic invasions considers purely lethal predation effects inferred from invertebrate presence/absence. These experiments demonstrate the need to better understand both the processes and impacts of predation by invasive species, which may include substantial nonlethal effects on the fitness and life history of endangered taxa.

The phylogenetic study was conducted to reveal the types of Corbicula species located on a selected river in Kelantan. The morphotypes and morphometric features were used to analyse the phenotypic analysis, and genotypes were examined exploiting the mitochondrial DNA cytochrome b (cytb) gene. A unique morphotype round (R) was discovered for every examined sample. Furthermore, there were significant differences (p<0.05) in the morphometric features (umbo length, UL; shell width, SW; and shell height, SH) between the C. fluminea populations. The mtDNA cytb sequences are used in the genotyping analysis to confirm that the assessed Corbicula is C. fluminea. Three genotypes were identified in the mtDNA cytb phylogenetic tree. In geographically isolated populations, phylogenetic trees showed polymorphism and minimal genetic variability, which aligned with the phenotypic characterisation. The results clarify the differences among C. fluminea and imply that Corbicula sp. in Kelantan originated from a single species. These findings are significant not only for biologists or those involved in ecology and ecosystems but also for the fisheries sector as it serves as the basis for breeding purposes, overcome the extinction, and enhancing the economy of the inland fishermen in Kelantan.

Freshwater bivalves in shallow waters are often exposed to extended periods of drought and are highly affected due to their limited mobility. Their adaptation to emersion is a key factor for survival, particularly during human-made unnatural water regime fluctuations or short-term droughts. In the current study, survival durations of two freshwater bivalve species (Unio terminalis, Unionidae and Corbicula fluminea, Cyrenidae) were tested under two experimental emersion conditions (presence of water-saturated sediment and without sediment). U. terminalis' mean survival duration more than doubled in the water-saturated sediment treatment (992 h) compared to treatment without sediment (448 h). For C. fluminea, the mean survival duration in the water-saturated sediment treatment (278 h) was over 50% longer than that recorded in the treatment without sediment (174 h). Both species probably made behavioral adjustments according to the environmental conditions to respond to the presence of the water-saturated sediment and maximized their survival chances. In general, U. terminalis survived significantly longer than C. fluminea in both treatments. No effects of size on survival were observed for either species.
