Artificial light at night decreases metamorphic duration and juvenile growth in a widespread amphibian.

Artificial light at night (ALAN) affects over 20% of the earth's surface and is estimated to increase 6% per year. Most studies of ALAN have focused on a single mechanism or life stage. We tested for indirect and direct ALAN effects that occurred by altering American toads' () ecological interactions or by altering toad development and growth, respectively.

Legacy of road salt: Apparent positive larval effects counteracted by negative postmetamorphic effects in wood frogs.

Road salt runoff has potentially large effects on wetland communities, but is typically investigated in short-term laboratory trials. The authors investigated effects of road salt contamination on wood frogs (Rana sylvatica) by combining a field survey with 2 separate experiments. The field survey tested whether wood frog larval traits were associated with road salt contamination in natural wetlands.
