I am a student studying the relation between bird richness and environmental factors.

Here are three kinds of bird richness: A, B, C. (continuous variable)

and five sorts of environmental factors: 1, 2, 3, 4, 5. (continuous variable)

ordinary least square was used for model selection in General linear model.

The significant rank was as followed (based on delta AIC):

Model A 45312 (high to low)

Model B 45132

Model C 43512

Please advise

how to quantify the distinct impacts

each variable brings to each model ( for example, factor 3) ?

Is ANOVA suitable for comparison in this regard ?

(ANOCA considers interaction between variables but model selection does not).

Thank you very much.
