## Abstract Concanavalin A exerts a reversible inhibition upon gastrulation and neurulation in the amphibian embryo. This inhibition depends on concentration and is attenuated when the embryonic capsules are left intact.
We have shown earlier that insulin has well-defined teratogenic effects on developing chicken embryos. These effects are chiefly, in fact probably exclusively, skeletal; but, in addition, general body dwarfing may exist. Depending on embryonic age at the time of treatment, different skeletal abnorma
## Abstract We examined the effects of atrazine (0โ20 mg/L) on embryos, larvae, and adult anuran amphibian species in the laboratory. Atrazine treatments did not affect hatchability of embryos or 96โh posthatch mortality of larvae of __Rana pipiens, Rana sylvatica__, or __Bufo americanus__. Further
Embryos and newly hatched larvae of three amphibian species, the spotted salamander (Ambystoma maculatum), the northern leopard frog (Rana pipiens), and the African clawed frog (Xenopus laevis), were exposed to fluoranthene and ultraviolet (UV) light in two scenarios. Embryos were exposed in a labor
