[R-meta] Help with spatial-temporal MLMA and post-hoc tests

Thank you again. I want to evaluate two things: (1) Does effect size change
throughout space and time? (2) Can this variation be explained by a
continuos moderator? I have several measure of effect size (Fisher's Z) for
different species. However, my data set is heterogeneous. For example, some
species have two measures of Z in different years, while other has more
than 10 replicates in the same study. I don't know how to answer those
questions in a meta-analysis using metafor package.
My second question is still open. I want to know how to conduct a post-hoc
test in a multi-level meta-analysis. May you help me?
