The enzyme-linked receptor assay (ELRA) detects estrogenic and anti-estrogenic effects at the molecular level of receptor binding and is a useful tool for the integrative assessment of ecotoxicological potentials caused by hormonally active agents (H

Bioassays as well as biochemical responses (biomarkers) in ecosystems due to environmental stress provide us with signals (environmentally signalling) of potential damage in the environment. If these responses are perceived in this early stage in eco

The frequency and intensity of harmful algal blooms (HABs) appear to be on the rise globally. There is also evidence of the geographic spreading of toxic strains of these algae. Consequently, methods had to be established and new ones are still neede

Immune function in bivalves can be adversely affected by long-term exposure to environmental contaminants. Investigating alterations in immunity can therefore yield relevant information about the relationship between exposure to environmental contami

A spatial and temporal survey of six sites in the Saguenay Fjord and of one adjacent site in the St. Lawrence River estuary (Quebec, Canada) was undertaken to study the possible effects of anthropogenic contaminant input on soft-shell clam (Mya arena

A simple and direct algebraic method of calculating PID tuning constants for unmeasured load rejection based on a linear differential-equation process model (including time delay) is presented. Methods are discussed for experimentally identifying the

The level of vitellogenin-like (Vg-like) proteins in the hemolymph of the soft-shell clam (Mya arenaria) was indirectly determined using an alkali-labile phosphate (ALP) measurement assay. Biochemical characterization of hemolymph from actively repro
