Dear Researchers!
I calculated the values of CCA, with 7 environmenta variables (independent) and 15 species (dependet variables), three different sites. The results are there in graphical form. Can anyone help me interpretate these results?
Please help!
There are some different options in the Past Statistical Software version four for running of this test. it could be used its options to better interpretation of the output.
Dear Khan,
I presume this graph has been generated via PAST?
I was facing the similar issues, as past doesn't generate a corresponding dataset for us to interpret (besides the axis scores).
Some links that helped me to interpret this was

From what I can infer from my graph, the lines (green) depicte the environmental variables, while the dotted depict your biotic components and the traingle, I presume is site?
To understand the relationship between the dots and the lines, you can look up the above link.
You basically have to make an angle from the dots to the lines to understand whichever is nearer. Kindly look at the section "Figure 2: Illustrative example of CCA triplot" under the given link.
Best regards
