Pipe refuge occupancy by herpetofauna in the Amazonia/Cerrado ecotone

Abstract

We evaluated the usefulness of arboreal pipe refuges for studying Neotropical herpetofauna, by quantifying the effects of microhabitat variables and pipe colouration on pipe occupancy rates. We used fifty five sets of refuges that each comprised three pipes with different colours (white, grey and black). We recorded 122 occupancy events by four hylid and one scincid species. Refuge colour did not significantly affect occupancy rates. Environmental data explained a significant portion (10.6%) of the total variance of occupancy, with vegetation type and height of opening being most important.
