| On The Cover:On the Cover: The widespread disappearance and
the occurrence of malformed frogs prompted investigations into potential
environmental causes for the events. An article (
Burkhart et al. , p. 841) and a research highlight (
Kavlock , p. 743) illustrate the difficulties in ascribing cause
and effect to the observations. Water pollution, UV light, micronutrient
loss, and fungal disease have all been implicated.
