Efficacy of Three Funnel Traps for Capturing Amphibian Larvae in Seasonal Forest Ponds

Abstract

Among the many techniques that have been used to study amphibians, funnel traps are commonly recommended to determine species presence, breeding success, and relative abundance of amphibian larvae in aquatic habitats. Several authors have discussed the advantages and disadvantages of funnel traps for sampling amphibian larvae (Adams et al. 1997; Fronzuto and Verrell 2000; Shaffer et al. 1994). However, recent reviews of methods for studying amphibians (Heyer et al. 1994; Olson et al. 1997) make it clear that more research is needed on the species-specific effectiveness of methods that have been proposed.
