INTRODUCTION
	Amphibian decline has become a major concern over the last decade, as species are becoming less common or disappearing altogether from areas where they had once been found. Causes of these declines have been widely debated. Human habitat destruction, fragmentation, increased UVB radiation, and the increased use of agricultural chemicals are thought by many to be major factors. However, amphibian populations are naturally variable from year to year.  Thus, long-term monitoring programs are necessary to separate human-caused declines from natural fluctuations. Many of these monitoring programs rely on manual calling surveys.  However, because calling behavior of anurans can be affected by time of day, season, geographic location, and environmental conditions, these factors must be considered when conducting amphibian monitoring programs.  Objective:    Document daily and seasonal anuran calling variation between two ponds and assess how geographic variation in calling activity might be used to optimize anuran monitoring protocol.
