A review of pipe and bamboo artificial refugia as a sampling tool in anuran studies

Abstract/Summary

Artificial pipe-like refugia have been used by researchers for more than 40 years in anuran studies, and captured 28 species, primarily (82%) hylid treefrogs. Early pipe-like refugia were made using cut pieces of bamboo in the tropical forests of Puerto Rico, but more recent studies have used synthetic pipes and have occurred primarily in the southeastern United States. Although some studies have addressed particular aspects of pipe design, the diverse characteristics of the refugia as well as their placement in the environment have varied greatly, making comparisons among studies difficult. Here, we summarize and evaluate information regarding pipe designs and placement, address potential concerns for researchers, and suggest studies necessary to better interpret the data gained from this technique in anuran studies.
