Amphibian hormonal induction
ثبت نشده
چکیده
Conservation breeding programs for the flagship species, the Wyoming toad (Bufo baxteri), Boreal toad (Bufo boreas boreas), Puerto Rican crested toad (Peltophryne lemur), and Chinese giant salamander (Andrias davidianus) are either completely or largely dependent on hormonal induction. Commercial production of African clawed toads (Xenopus spp.) and also numerous other species rely on hormonal induction.

Fish and Amphibian Models for Developmental Endocrinology
The hormonal control of ontogeny in fish and amphibians is reviewed. Neuroendo. crine regulation and actions of metabolic and osmoregulatory hormones (thyroid, interrenal, pituitary, pancreas, and gut) during amphibian and fish metamorphosis and the parr-smolt transformation of juvenile salmon are considered. The developmental significance of hormones in egg yolk is discussed. It is concluded t...
متن کاملHormonal regulation of the epithelial Na+ channel: from amphibians to mammals.
High-resistance epithelia derived from amphibian sources such as frog skin, toad urinary bladder, and the A6 Xenopus laevis kidney cell line have been widely used to elucidate the underlying mechanisms involved in the regulation of vectorial ion transport. More recently, the isolation of high-resistance mammalian cell lines has provided model systems in which to study differences and similariti...
متن کاملHormonal priming, induction of ovulation and in-vitro fertilization of the endangered Wyoming toad (Bufo baxteri)
The endangered Wyoming toad (Bufo baxteri) is the subject of an extensive captive breeding and reintroduction program. Wyoming toads in captivity rarely ovulate spontaneously and hormonal induction is used to ovulate females or to stimulate spermiation in males. With hormonal induction, ovulation is unreliable and egg numbers are low. The sequential administration of anovulatory doses of hormon...

BACKGROUND Protocols for the hormonal induction of ovulation and oviposition are essential tools for managing threatened amphibians with assisted reproduction, but responses vary greatly between species and even broad taxon groups. Consequently, it is necessary to assess effectiveness of such protocols in representative species when new taxa become targets for induction. The threatened genus Mi...
متن کاملLeaping forward in amphibian health and nutrition.
The Epidemiology Working Group, a subgroup of the participants of the Disney's Animal Kingdom Workshop on "Ex situ Amphibian Medicine and Nutrition," identified a critical need to design and implement approaches that will facilitate the assessment and evaluation of factors impacting amphibian health. In this manuscript, we describe and summarize the outcomes of this workshop with regards (a) th...
