Intraspecific scaling and early life history determine the cost of free-flight in a large beetle(Batocera rufomaculata)
《Insect Science》2024年第2期524-532,共9页Tomer Urcai Eran Levin Eran Gefen Gal Ribak 
The scaling of the energetic cost of locomotion with body mass is well documented at the interspecific level.However,methodological restrictions limit our understanding of the scaling of flight metabolic rate(MR)in fr...
