Testing this significance of a factor in a mixed-model "ANCOVA"

species. I'm interested in whether the rate of bone length scaling
to body mass (i.e., growth) differs between species.
My call to lme looks like this:
model=lme(lghumlen ~ species + lgbmkg, random= ~ lgbmkg | id,
correlation=corCAR1(), weights=varExp())
where lghumlen is the log of humerus length and lgbmkg is the log of
body mass.
If I ask for a summary of my model, I get this from the table of
fixed effects:
Fixed effects: lghumlen ~ species + lgbmkg
Value Std.Error DF t-value p-value
(Intercept) 3.567226 0.02059541 540 173.20495 0.000...
