Biomagnification is the process where xenobiotic substances are transferred from food to an
organism resulting in higher concentrations compared with the source. It is widely believed …

Exposure to methylmercury (MeHg) can result in detrimental health effects in wildlife. With
advances in ecological indicators and analytical techniques for measurement of MeHg in a …

Environmental mercury (Hg) contamination is an urgent global health threat. The complexity
of Hg in the environment can hinder accurate determination of ecological and human health …

Measures of trophic position (TP) are critical for understanding food web interactions and
human‐mediated ecosystem disturbance. Nitrogen stable isotopes (δ15N) provide a …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

Stable nitrogen isotope signatures (δ 15 N) are increasingly used to infer the trophic position
of consumers in food web studies. Interpreting the δ 15 N of consumers relative to the δ 15 N …

Species invasions pose a serious threat to biodiversity and native ecosystems,; however,
predicting and quantifying the impacts of invasive species has proven problematic,,,. Here …

Although trophic cascades (indirect effects of predators on plants via herbivores) occur in a
wide variety of food webs, the magnitudes of their effects are often quite variable. We …

Studies of lake ecosystems generally focus on pelagic food chains and processes. Recently,
there has been an emerging recognition of the importance of benthic production and …

Les rapports d'un isotope stable de l'azote (delta 15N) sont couramment utilisés pour
représenter la structure trophique des systèmes aquatiques; pourtant, la capacité du delta …
