Oocyte maturation in the toad Rhinella arenarum (Amphibia, Anura): Evidence of cAMP involvement in steroid production and action [PDF]
, 2018 In this work, we describe the participation of the adenylate cyclase/3′-5′-cyclic adenonsine monophosphate (cAMP) pathway in the seasonal follicular secretion of progesterone (P 4 ) and testosterone (T), and its relationship with the maturation of ...

Amphibian disease and declines: Chytridiomycosis [PDF]
Microbiology Australia, 2005 Chytridiomycosis is caused by Batrachochytrium dendrobatidis, a unique fungal organism of the phylum Chytridiomycota, a large group of ubiquitous fungi better known as silent digesters of organic waste or as parasites of nematodes and unicellular organisms such as pollen or algae. Chytr is the Greek root for earthen pot, Batracho ? frog and dendrobates
