Wildlife exhibits various sex-determination systems where sex chromosomes and environmental
temperatures may both contribute to individual sexual development. The causes and …

Many chemical pollutants have endocrine disrupting effects which can cause lifelong
reproductive abnormalities in animals. Amphibians are the most threatened group of vertebrates, …

Populations of ectothermic vertebrates are vulnerable to environmental pollution and climate
change because certain chemicals and extreme temperatures can cause sex reversal …

Background One of the dangers of global climate change to wildlife is distorting sex ratios
by temperature-induced sex reversals in populations where sex determination is not …

Despite intensive ecotoxicological research, we still know relatively little about the ecological
impacts of many environmental contaminants. Filling these knowledge gaps is particularly …

The development of genetic methods broadens the scope of non-invasive sample types. Large
shed feathers are good material for genetic analyses, since they are easy to collect and a …

Extreme temperatures during heat waves can induce mass-mortality events, but can also
exert sublethal negative effects by compromising life-history traits and derailing sexual …

Anthropogenic environmental change poses a special threat to species in which genetic
sex determination can be overwritten by the thermal and chemical environment. Endocrine …

Sex reversals whereby individuals of one genetic sex develop the phenotype of the opposite
sex occur in ectothermic vertebrates with genetic sex-determination systems that are …

Sex reversal is a mismatch between genetic sex (sex chromosomes) and phenotypic sex (reproductive
organs and secondary sexual traits). It can be induced in various ectothermic …
