AbstractThis is the characterisation of the reproductive dynamics of Rhinella schneideri in an urban area during two non‐consecutive periods. Germ cells are similar to those of other anuran species, but some characteristics were more marked for R. schneideri, such as the morphological similarity of spermatogonia and oogonia, which may be related to ...

Stressors can increase plasma glucocorticoid (GC) levels and decrease plasma androgen levels in different species of vertebrates. GCs can have immune-enhancing or immunosuppressive effects, which are dependent upon stress duration and intensity. The worldwide decline in amphibian populations is strongly linked to an array of different stressors.
