Does adrenal responsiveness vary with sex and reproductive status in Egernia whitii, a viviparous skink?
In mammals, oestrogens generally stimulate adrenal function whilst androgens are inhibitory, and gestating females down-regulate their acute response to stressors in order to protect currentExpand
Water Balance and Arginine Vasotocin in the Cocooning Frog Cyclorana platycephala (Hylidae)
It is well established that forming a cocoon, for frog species capable of doing so, markedly reduces evaporative water loss; however, the capacity of cocooned frogs to maintain hydration duringExpand
Water balance of field-excavated aestivating Australian desert frogs, the cocoon-forming Neobatrachus aquilonius and the non-cocooning Notaden nichollsi (Amphibia: Myobatrachidae)
SUMMARY Burrowed aestivating frogs of the cocoon-forming species Neobatrachus aquilonius and the non-cocooning species Notaden nichollsi were excavated in the Gibson Desert of central Australia.Expand
Water relations of the burrowing sandhill frog, Arenophryne rotunda (Myobatrachidae)
Arenophryne rotunda is a small (2–8 g) terrestrial frog that inhabits the coastal sand dunes of central Western Australia. While sand burrowing is a strategy employed by many frog species inhabitingExpand
Adrenal and white cell count responses to chronic stress in gestating and postpartum females of the viviparous skink Egernia whitii (Scincidae).
This study investigates the relationships between plasma corticosterone concentrations and white cell counts in captive females of the viviparous lizard Egernia whitii during two phases of theExpand
Burrows of desert-adapted frogs, Neobatrachus aquilonius and Notaden nichollsi
The non-cocooning frogs, Notaden nichollsi and Uperoleia micromeles, and the cocoon-forming frog, Neobatrachus aquilonius, burrow underground to survive in the hot, dehydrating arid interior ofExpand
