Abundance of green tree frogs and insects in artificial canopy gaps in a bottomland hardwood forest

Abstract

We found more green tree frogs (Hyla cinera) in canopy gaps than in closed canopy forest. Of the 331 gree ntree frogs observed, 88% were in canopy gaps. Likewise, higher numbers and biomasses of insects were captured in the open gap habitat. Flies were the most commonly collected insect group accounting for 54% of the total capture. These data suggest that one reason gree tree frongs were more abundant in canopy gaps was the increased availibility of prey and that small canopy gaps provide early successional habitats thare are beneifical to green tree frog populations.
