BBQ Ecologist

Adult Gray Treefrog. A treefrog is sitting in brown, dead cattail fronds. The treefrog has a mottled pattern of light and dark green patterns on its back.

Figure showing the amount of daylength in the three treatments from the start of the experiment (Day 0) to the end of the experiment (around day 90). The early treatment simulates breeding starting in april, and the daylength is about 12.5 hours per day, and goes up to about 15 hours per day. The average treatment simulates breeding in july, and simulates breeding starting in July and at 15 hours of light per day, and going down to around 12 hours of light per day. The late treatment simulates breeding in mid-august. Late treatment starts with about 14 hours of light per day, and goes down to about 10 hours of light per day.

Plot of total glycogen in liver. The values are low (between 0 and 20) for frogs from the early and average photoperiod, but are much higher (40) for frogs from the late treatment.

Figure showing size-corrected growth rate (grams per day) from the three photoperiod treatments. The late photoperiod treatment has the lowest growth rate, significantly lower than the average photoperiod, and lower (but not significantly different from) the early photoperiod.

New from CWRU alumn Troy Neptune, with Diana Koester (CLE Metroparks Zoo) in @animalecology.bsky.social. Gray treefrogs use daylength as a seasonal cue to prepare for winter. Autumn daylength triggers frogs to accumulate 14-fold more liver glycogen than summer photoperiod.
