Discussion
I hypothesized that the smaller the body mass, the faster the basal metabolic rate and the larger the body mass, the slower the basal metabolic rate. Once applying the data into a scatter plot, I was surprised to find the opposite is true.
Other finding were in regard to the relationships that exist between body mass and BMR / mass specific BMR in birds and mammals
In contrast to my original hypothesis "mammals that live in hot arid (tropic) environments will have a lower BMR than species from temperate environments" the data finds the opposite as true. Mammals that live in climates with extreme temperatures will have a higher BMR than species from temperate environments. This is because the body has to work harder to maintain its normal body temperature, which increases the BMR.
There is a positive correlation between body mass and BMR in birds and in mammals. There is an inverse relationship between body mass and mass-specific BMR in birds and mammals.
An inverse relationship between body mass and mass-specific BMR may be explained as: the smaller the body mass - the higher the mass-specific BMR. The larger the body mass the lower the mass-specific BMR.
Introduction
Factors that influence variation in BMR include body mass, diet, climate, habitat, and type of reproduction
Hypothesis
Mammals that live in hot arid (tropic) environments will have a lower BMR than species from temperate environments
Findings: Mammals that live in climates with extreme temperatures will have a higher BMR than species from temperate environments. This is because the body has to work harder to maintain its normal body temperature, which increases the BMR.
Readers interest
Did you know there is a relationship between body mass and BMR in both birds and mammals?
Approach
Extract data using Quaadvark
Analyze and graph data using Excel
Basal Metabolic Rate, BMR, is defined as is the number of calories you burn as your body performs basic (basal) life-sustaining function (Garnet health 2016 Jul 1).
This includes the energy used to maintain the basic functions of living and breathing, including:
Cell production
Respiration
Beating of the heart
Nutrient processing
Body temp maintenance

Background
There is a positive correlation between body mass and BMR in mammals and in birds. There is an inverse relationship between between mass-specific body mass and BMR in birds and mammals.
My hypothesis
Mammals that live in hot, arid (tropic) environments will have a lower BMR than species from temperate environments.
Methods
Subects
Birds and mammals
Design
Create excel spreadsheet with relevant information for birds and mammals
Procedures
Add chart elements to design charts (axises, titles, trendlines)
Calculate mean and standard deviation for the T Test
Use graphing tools to create scatterplots, bar graphs,
T test is used to determine if the two groups are statistically different - use bar graphs to illustrate similarities / differences
Compare body size between birds and mammals
Compare basal metabolic rate (BMR) between birds and mammals
Extract relevant data from Animal Diversity Web and save to an excel file
Compare mass-specific basal metabolic rate (BMR) between birds and mammals
Analyze data from individual hypothesis

Results
As body mass increases so does BMR
There is an inverse relationship present between mass-specific body mass and BMR in mammals
There is a positive correlation between body mass and BMR in birds and mammals
Average BMR for birds will be greater than the average BMR for mammals
Average body mass of birds will be less than the average body mass for mammals
My hypothesis "mammals that live in hot arid (tropic) environments will have a lower BMR than species from temperate environments" was incorrect
Mammals that live in tropic climates actually have a higher BMR that species from temperate environments
