Filled with practical guidance on how to conduct selenium risk assessments in the aquatic
environment, this book offers the latest information on assessment techniques, gives the …

Amphibians provide essential ecosystem services and are facing global decline. Exposure
to contaminants is a contributing factor to this decline, with permeable skin and early aquatic …

The loss of genetic diversity, due to exposure to chemical contamination (genetic erosion), is
a major threat to population viability. Genetic erosion is the loss of genetic variation: the loss …

In this chapter we identify the state-of-the-science regarding selenium (Se) bioaccumulation
and trophic transfer. We discuss Se bioaccumulation and how its unique attributes tie …

Despite the influence that amphibians have on the flow of energy and nutrients in ecological
systems, the role that amphibians play in transporting contaminants through food webs has …

In this study an assessment is made of how the marsh frog P. ridibundus individuals, being
long-term inhabitants of an anthropogenically polluted habitat, are affected and what …

Although many amphibian populations around the world are declining at alarming rates, the
cause of most declines remains unknown. Environmental contamination is one of several …

Amphibian population declines have been documented worldwide and environmental
contaminants are believed to contribute to some declines. Maternal transfer of …
