Summary 1 The use of stable isotopic techniques to study animal diets and trophic levels
requires a priori estimates of discrimination factors (Δ13C and Δ15N, also called …

The study of organic contaminants at high altitudes is motivated by the potential risk that they
pose to humans living in, or depending on resources derived from, mountains, and to …

Stable isotope analysis (SIA) has become a powerful tool for ecotoxicologists to study
dietary exposure and biomagnification of contaminants in wild animal populations. The use …

BACKGROUND: Because of concern about the recently increasing levels of biological Hg in
some areas of the Arctic, we examined the literature concerning the long-term changes of …

The aim of this study was to determine the levels of Pb, Cd, Co and Cr in duck eggs and
duck meat and to assess the risk of carcinogenic and non-carcinogenic effects caused by …

Birds can be impacted by pollution but are seldom used as bioindicators. One exception
involves the Dippers Cinclus spp., a genus of five passerines adapted uniquely to swim and …

In this study, we investigated whether bird feathers can be used as a non-destructive
biomonitor for organic pollutants. We analysed the outermost tail feathers of 8 terrestrial and …

We investigated aquatic insect utilization and PCB exposure in riparian spiders at the Lake
Hartwell Superfund site (Clemson, SC). We sampled sediments, adult chironomids …

The exposure assessment component of a Wildlife Ecological Risk Assessment aims to
estimate the magnitude, frequency, and duration of exposure to a chemical or environmental …

Animal behaviour has broad ecological and evolutionary implications. Among other things, it
drives social group and population dynamics, affects interspecific interactions and …
