The fundamental physiology and biology processes of Sterechinus neumayeri embryos and larvae and how they are affected by increased UV radiation, McMurdo Sound

[ Update this Record ]

Summary
Abstract: Three key processes in the embryos and larvae of the sea urchin Sterechinus neumayeri were examined to determine how they respond to environmental changes. In situ experiments were carried out at Cape Evans and on the sea ice edge with the blastula/gastrula larval stage.
1. Genetic expression of the photolyase enzyme: Embryos were exposed to ambient UVR at varying depths (0.5, ... View entire text
