Summary
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
