Vaginal temperature, collar activity, and fecal progestagen. Graphs from two captive female moose that were 9 years (IDs = 30681 and 30684) containing daily values for mean vaginal temperature (blue line) and daily sum of activity (red line) recorded between July 23rd and November 22nd, 2021, and fecal progestagen concentrations recorded between August 23rd to October 15th, 2021. Dashed vertical blue line = onset of luteal activity, which is on the 23rd of September for both graphs. Dashed horizontal red line = individual fecal progestagen threshold
