Consequences of embryonic UV-B exposure for embryos and tadpoles of the plains leopard frog

Article Abstract:

Research indicates that the impact of ultraviolet-B radiation exposure may not manifest until later stages of development, which could affect long-term success of species. In studies using plains leopard frogs, no differences were noted in embryo hatching success between exposed and unexposed groups, but tadpole growth and development occurred more slowly in UV-B exposed specimens.

Identifying Habitat Variables Important to the Rare Columbia Spotted Frog in Utah (U.S.A.): an Information-Theoretic Approach

Article Abstract:

Characteristics of Columbia spotted frog habitat are identified. These include ponds that maintain comparatively constant water temperature, have high and emergent vegetation cover, and do not experience seasonal shrinkage. Applications to conservation efforts are also discussed.

Effects of the Interaction between Genetic Diversity and UV-B Radiation on Wood Frog Fitness

Article Abstract:

Ultraviolet B radiation exposure on wood frog populations was found to increase deformity rates and larval mortality. The latter was especially significant among populations exhibiting low genetic diversity. Findings indicate that UV-B radiation contributes to amphibian decline.
