Mammalian
vs.
Aves
Background
-BMR is the rate of energy used over time
and is an estimate of the number of calories burned
Hypothesis
-The BMR and mass specific BMR is higher in mammals than in birds
Introduction:
-Methods/Procedure: Extracting data, calculating mass specific BMR using statistical tests
-Design: Body mass, BMR, and mass specific BMR were used to compare different species/classes of birds and mammals
Subjects
Birds: certain species were omitted
Mammals: certain species were omitted
Aptenodytes
patagonicus, Junco hyemalis, and Diomedea exulans, Aquila chrysaetos, Phoebastria
immutabilis, Apteryx australis, Struthio camelus, Uria aalge, and Gallus gallus.

Abstract
Background:
-BMR is the amount of energy used at rest
-Relationship between BMR and body mass
-All organisms depend on metabolism
Methods:
-Extracting data from Quaardvark database
Results:
-The average BMR and body mass of mammals is much greater than birds
-All graphs and statistical charts to show correlations
click to edit
Discussion:
-Lifespan and mass specific BMR are independent of body mass
Possible errors include outliers and common data collection errors
