Abstract
ABSTRACT Egg inviability at oviposition is a possible explanation for the high rate of early-stage embryo death of eggs laid by green turtles at Raine Island, the largest green turtle nesting aggregation in the world. We tested this possibility by assessing egg viability of freshly laid eggs. We found that green turtle eggs laid at Raine Island have high viability at their time of laying, and that there was no relationship between egg viability and early-stage embryo death or hatching success within a clutch. Hence, the inviable egg at oviposition hypothesis cannot explain the high death rate of early-stage embryos that is characteristic of green turtle clutches laid at Raine Island.
期刊介绍:
Australian Journal of Zoology is an international journal publishing contributions on evolutionary, molecular and comparative zoology. The journal focuses on Australasian fauna but also includes high-quality research from any region that has broader practical or theoretical relevance or that demonstrates a conceptual advance to any aspect of zoology. Subject areas include, but are not limited to: anatomy, physiology, molecular biology, genetics, reproductive biology, developmental biology, parasitology, morphology, behaviour, ecology, zoogeography, systematics and evolution.
Australian Journal of Zoology is a valuable resource for professional zoologists, research scientists, resource managers, environmental consultants, students and amateurs interested in any aspect of the scientific study of animals.
Australian Journal of Zoology is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
