  1. A comparison and correlation between anuran activity (evaluated by the number of captures) and different abiotic variables between May 2010 and April 2011 in subtemperate wetlands in southernmost Brazil. The number of samples (n samples) used for all statistical tests was 48. See “Methods” section for a detailed explanation
  2. N the number of captures in pitfalls, NA not applicable
  3. *Significant variation
