Stratification stability of tropical lakes and their sensitivity to climate Open
Tropical lakes experience less thermal convection than temperate lakes and can be stably stratified by temperature gradients alone. Deep tropical lakes are often presumed meromictic, but conditions for sustained meromixis are poorly constr…

<span>eDNA</span>‐based detection reveals invasion risks of a biofouling bivalve in the world's largest water diversion project Open
Environmental DNA (eDNA) has increasingly been used to detect rare species (e.g., newly introduced nonindigenous species) in both terrestrial and aquatic ecosystems, often with distinct advantages over traditional methods. However, whether…

Golden mussel (<i>Limnoperna fortunei</i>) survival during winter at the northern invasion front implies a potential high‐latitude distribution Open
Aim Golden mussel Limnoperna fortunei is an invasive bivalve in many freshwater ecosystems in Asia and South America. Cold winter temperatures are expected to restrict its spread to high‐latitude areas. Cold tolerance and potential distrib…

Screening marker sensitivity: Optimizing eDNA‐based rare species detection Open
Aim Environmental DNA (eDNA)‐based techniques are useful tools in disciplines such as conservation biogeography at local to global scales since they provide promising methods to locate organisms at low abundance. Here, we raise a largely o…

Conventional versus real‐time quantitative PCR for rare species detection Open
Detection of species in nature at very low abundance requires innovative methods. Conventional PCR (cPCR) and real‐time quantitative PCR (qPCR) are two widely used approaches employed in environmental DNA (eDNA) detection, though lack of a…

Assessment of hazard metrics for predicting field benthic invertebrate toxicity in the Detroit River, Ontario, Canada Open
Numerical sediment quality guidelines (SQGs) are frequently used to interpret site-specific sediment chemistry and predict potential toxicity to benthic communities. These SQGs are useful for a screening line of evidence (LOE) that can be …

Comparison of the Toxicokinetics and Bioaccumulation Potential of Mercury and Polychlorinated Biphenyls in Goldfish (<i>Carassius auratus</i>) Open
Both mercury (Hg) and polychlorinated biphenyls (PCBs) demonstrate food web biomagnification in aquatic ecosystems, yet their toxicokinetics have not been simultaneously contrasted within a common fish species. This study quantifies uptake…
