title: Data from: phenology and environmental determinants of explosive breeding in gliding treefrogs: diel timing of rainfall matters

description: The influence of abiotic and biotic factors on the temporal pattern of
 calling and breeding for many temperate anurans is well understood.
 However, few studies have documented patterns of reproduction in
 explosive-breeding tropical frogs or incorporated multiple environmental
 factors in their analyses, especially across multiple breeding seasons. We
 combine long-term natural history observations and automated data
 collection methods with boosted regression tree (BRT) analysis to
 determine the phenology and determinants of explosive breeding in the
 gliding treefrog, Agalychnis spurrelli. We monitored breeding for a total
 of 418 days across three breeding seasons and determined the relative
 importance of several environmental factors on the probability of calling
 and breeding activity. Our study population of A. spurrelli on Costa
 Rica’s Osa Peninsula forms breeding aggregations up to 11 times per year
 during 1–2-day long explosive-breeding events, from late May to
 mid-September. Calling and breeding activity are strongly and positively
 related to accumulated rainfall during the previous 24 and 48–24 hours
 before, particularly rainfall during the afternoon and evening.
 Day-of-year, days since breeding occurred, and lunar phase also influence
 reproductive activity. This study provides the first description and
 analysis of the phenology and factors that predict explosive breeding in
 A. spurrelli and illustrates the value of using automated data collection
 paired with BRTs for analysis of complex ecological data.
