The direct effects of UV radiation on embryo and larval development and survival, and DNA damage of Sterechinus neumayeri
Entry ID: K068_2002_2006_NZ_2

Abstract: Gastrulation is a critical point in the development of an embryo. Damage to embryos prior to gastrulation via UVR effects on cytokinesis or DNA will have a dramatic negative effect on embryo survival. Once embryos exposed to UVR complete gastrulation, there may be delays in the development program and mortality associated with incomplete or abnormal metamorphosis to larvae. One way to assess these ... View entire text
