Invasive Bivalve Species Dynamics and Environmental Tolerance
Summary
Invasive bivalve molluscs have emerged as a major driver of ecological change in freshwater, estuarine and coastal systems worldwide. Their capacity to establish dense populations often leads to habitat alteration, native species displacement and economic impacts on industry and infrastructure. Key mechanisms underpinning invasion success include broad environmental tolerance, rapid growth and high reproductive output, often coupled with versatile feeding strategies. Environmental tolerance is determined by the interaction of abiotic factors such as salinity, temperature and substrate availability, which together shape survival thresholds, dispersal potential and competitive outcomes. Physiological and metabolic plasticity—mediated by differences in enzyme activity, microbiota composition and genetic diversity—enables invasive bivalves to colonise novel habitats and withstand environmental fluctuations. Human-mediated transport vectors, notably ship hull fouling and ballast water, circumvent natural dispersal barriers, extending the geographic range of non-native species. Understanding the interplay between species-specific tolerance limits, environmental variability and anthropogenic vectors is essential for predicting future spread, designing targeted management and mitigating impacts on native biota and ecosystem services.

Technical terms
Metagenomics: Culture-independent sequencing of all genetic material in a sample to characterise microbial community composition and function.
Metabolomics: Comprehensive analysis of small-molecule metabolites within cells or tissues to infer metabolic pathways and physiological states.
Haplotype diversity: Measure of the number and frequency of distinct genetic lineages within a population, reflecting introduction history and adaptive potential.
Practical Salinity Unit (PSU): Dimensionless scale for quantifying seawater salinity based on conductivity ratios, used to define tolerance ranges for aquatic organisms.
Biofouling: Unwanted accumulation of aquatic organisms on submerged surfaces, such as ship hulls, facilitating transport of invasive species.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
