Is it possible to receive the standard errors of the variances in metafor (and
do a Z-test)?

Thank you for your reaction, it worked.
However, I'm wondering if this is the right way to test whether there is
significant variation on one of the two levels. The results of the anova
of the variances in
metafor (and do a Z-test)?

I think that if you set sigma2 to a vector of length 2 it will be possible.
