Field metabolic rates of 5 female giant pandas measured with DLW at different locations during different seasons.

Studbook number	Panda age	Season	Location	Mass (kg)	Ambient temperature (°C)	FMR CO2 ml/g/h	FMR O2 ml/g/h	FMR KJ/day	Predicted FMR KJ/day
1000	2.4	Autumn	Panda Valley	58.1	14.0	0.22	0.25	7143	15,133.9
1000	3.5	Winter	Daxiangling	68.9	− 2.4	0.74	0.82	28,045	17,151.4
881	5.0	Summer	Daxiangling	102.4	18.2	0.34	0.38	19,417	22,940.7

853	7.3	Autumn	Panda base	95.4	14.9	0.45	0.50	23,592	21,778.9
1008	3.4	Winter	Panda base	93.6	12.1	0.24	0.27	12,435	21,476.5

Pandas 881 and 853 are adults. The others are sub-adults. The FMR was calculated using an RQ of 0.9. The body mass vs. FMR equation of Nagy³⁹ was used to predict FMR of a studied giant panda. The values for FMR (KJ/day) in this table differ from those in Bi (2020)⁵⁵ (see Supplementary Information).
