Evidence for ecological tuning of anuran biofluorescent signals.

Although biologists have described biofluorescence in a diversity of taxa, there have been few systematic efforts to document the extent of biofluorescence within a taxonomic group or investigate its general significance. Through a field survey across South America, we discover and document patterns of biofluorescence in tropical amphibians. We more than triple the number of anuran species that have been tested for this trait.

A new cryptic species of terrestrial breeding frog of the Group (Anura, Strabomantidae) from montane forests in Ayacucho, Peru.

Based on morphological and molecular characters, we describe a new species of terrestrial breeding frog of the Group from montane forests of La Mar Province, Ayacucho Department in southern Peru, at elevations from 1200 to 2000 m a.s.l.

A new species of Atelopus (Anura: Bufonidae) from southern Peru.

We describe a new harlequin frog (genus Atelopus) from the cloud forest near Anchihuay (Anco District, Ayacucho Department) from 2000 to 2150 m elevation in southern Peru, representing the first record for the genus in the Department of Ayacucho. The new species has a maximum snout-vent length of 21.5 mm in females and 21.
