Effects of Temperature and Precipitation on Breeding Migrations of Amphibian Species in Southeastern Norway

Table 3

Temperature statistics and specific dates for the first day of observation of T. cristatus from 2010 to 2014. Precipitation levels are not included in the table as they were all 0–0.1 mm. Detailed variable descriptions are provided in Table 2. First observations of L. vulgaris coincided with T. cristatus for all years, except for 2011 and 2014, where the first observations were registered one and eight days later, respectively.
