Basal Metabolic Rate Influence on Life Span of Birds and Mammals
Results
Slightly weak correlations are found between BMR and Lifespan in both Birds and Mammals. There are a few more outliers with mammals.
Mass specific BMR over Lifespan shows a slightly strong negative, a nonlinear relationship in Birds. Lower BMR show to have a longer Lifespan. The correlation in mammals is considerably weaker.

Disscussion
There is more research needed on lifespans vs mass specific BMR in Mammals do ti the clustering effect of data points,
We had to omit

data points due to their extreme numbers.
Data concludes that there is a relationship between Body Mass and life span, this also goes for BMR vs lifespan
Limitations:
Seen in (Fig.) As body mass (grams) increased Lifespan (Y) also increase in Birds and Mammals.
Abstract
Methods
Data collected from Animal Diversity Web Quaardvark
Tested for Birds and Mammals
Results
Slightly weak correlations are found between Body mass and Lifespan in bothe Birds and Mammals, as well as, BMR vs. Lifespan. Mammals have weaker correlations.
Background
Hypothesis: The lifespan in both birds and mammals will increase due to an increase is their Basal Metabolic Rate.
There is a strong correlation between body mass and metabolic rates in both Birds and Mammals.
Introduction
Glazier D, 2008 study on Body mass vs BM shows a strong relationship in Birds and Mammals.
Speakman J research on the correlation with body mass, BM and lifespan tell us there is still more room for studying life spans correlation with MR.
If there is a correlation with body mass and MR, will there be the same correlation when lifespan is introduced?
Hypothesis: The lifespan in both birds and mammals will increase due to an increase is their Basal Metabolic Rate.
Does MR have an impact of life span in Birds and Mammals?
Method
Dependent variable: Lifespan
Independent variable: Body mass and BMR
Data collected for Birds and Mammals
Data collected are averages for the whole species
The data collected for lifespan are wild non-gender specific.
Data extracted from Animal Diversity Web Quaardvark database.
