Endocrine disrupting chemicals (EDCs) are ubiquitous in aquatic and terrestrial
environments. The main objective of this review was to summarize the current knowledge of …

Agricultural landscapes, although often highly altered in nature, provide habitat for many
species of amphibian. However, the persistence and health of amphibian populations are …

In the XX/XY sex-determining system, the Y-linked SRY genes of most mammals and the
DMY/Dmrt1bY genes of the teleost fish medaka have been characterized as sex …

Most amphibians lack morphologically distinguishable sex chromosomes, but a number of
experimental techniques have shown that amphibian sex determination is controlled …

A large number of ultraviolet (UV)-absorbing compounds, usually present in personal-care
products, textiles exposed to UV radiation and plastics materials, elicit hormonal activity in …

The US Congress has passed legislation requiring the US Environmental Protection Agency
(US EPA) to develop, validate, and implement screening tests for identifying potential …

Atrazine is a potent endocrine disruptor that both chemically castrates and feminizes male
amphibians. It depletes androgens in adult frogs and reduces androgen-dependent growth …

A Y-linked gene, DMY/dmrt1bY, in teleost fish medka and a Z-linked gene, DMRT1, in
chicken are both required for male sex determination. We recently isolated a W-linked gene …

Globally, amphibians are undergoing a precipitous decline. At the last estimate in 2004,
32% of the approximately 6000 species were threatened with extinction and 43% were …

Evidence shows that environmental compounds can interfere with the endocrine systems of
wildlife and humans. The main sink of such substances, called endocrine disruptors (EDs) …
