what is the meaning of mantel test results to compare 2 matrices ??

Matrix 1: Data Distance Matrix

Matrix 2: Data Distance Matrix

Matrices are 355 x 355

Observed Z = 3894672599.85108

Correlation = 0.31206

t = 17.81190

Left-tailed p = 1.00000

Right-tailed p = 0.00000

Two-tailed p = 0.00000

Permutation Results (999 permutations)

# of Permutations < Observed = 999

# of Permutations > Observed = 0

# of Permutations = Observed = 1

Left-tailed p = 1.00000

Right-tailed p = 0.00100

Why do you want to do a test, if you don't know what you are testing???

Is this for homework?

The Mantel test measures the correlation between two distance matrices. The null hypothesis of the test is that the distances in one matrix are not linearly correlated with the distances in the other. If you don't know what a test does, you should learn about it, in particular about when it is valid and when it is not. In this case, it is important that the distances in the two matrices are computed using variables that are independent between the two matrices.

This is where you need to do your homework. Try to understand the question that you're asked, whether the Mantel test is the appropriate answer and if so why.
