General
What does it mean?
100
These animals could not be used in this experiment because water molecules move through them too fast to detect accurately
What is water-breathing and amphibious animals?
100
This is the major determinant of daily energy and food requirements within each taxonomic class
What is body size?
100
This is the most essential resource needed by animals their surroundings
What is energy?
100
This is the meaning of FMR
What is field metabolic rate?
200
The results for these animals were mostly for the breeding season, when labeled individuals could be recaptured reliably
What are birds?
200
This type of thermal physiology is the more energy-expensive lifestyle
What is endothermy?
200
This form of chemical potential energy is the most important form of energy to animals
What is food?
200
This is the meaning of BMR
What is basal metabolic rate?
300
The data for these animals were collected during the part of the year that they were abroad and active, not hibernating
What are reptiles?
300
This animal recorded the lowest FMR in the experiment
What is gecko?
300
These three classes of animals were used in the experiment
What are mammals, birds, and reptiles?
300
This is the meaning of DLW
What is doubly labeled water?
400
The rate of production of this molecule was measured in order to estimate an animals FMR
What is carbon dioxide (CO2)?
400
This number is how many times greater the FMR of an endotherm is compared an equivalent-sized ectotherm
What is 30 times greater?
400
This number of species of terrestrial vertebrates were used in this study
What is 229 species?
400
This large marine mammal recorded the highest FMR in this experiment
What is a seal?
500
These two radioactive isotopes are used in the DLW method so that we can track their washout rates
What are hydrogen and oxygen?
500
The FMR of a small endotherm was highest during this season
What is Winter?
500
On a seasonal and annual basis, animals consume additional food which provides substance for these two reasons
What are growth and reproduction?
500
Ectothermy and endothermy describe this characteristic
What is thermal physiology?
