Comparative effects of ambient ultraviolet-B radiation on two sympatric species of Australian frogs

Article Abstract:

The survivorship of embryos of tadpoles of a declining species of frog, Litoria verreauxii alpina, is compared with that of a sympatric nondeclining species, Crinia signifera, under three ambient ultraviolet-B (UV-B) treatments, unshielded, control, and UV-B excluding. The results support the hypothesis that ultraviolet radiation is likely to be a contributing factor in the disappearance of L.V. alpina at high elevations in southern Australia.

Invasion of exotic plant species in tallgrass prairie fragments

Article Abstract:

Research examines the effects of fragment size, diversity of native plant species, and location on exotic plant species invasion at 25 tallgrass prairie sites in Central North America and other geographical sites as measured by exotic species richness. Results suggest that timing determines the success of exotic species in the tallgarass prairie. Data do not show any significant relationships between native and exotic species richness.
