Query: A meridian lemma for fully alternating links in thickened surfaces   Menasco showed that a closed surface in the complement of a non-split prime
alternating link in $S^3$ contains a circle isotopic in the link complement to
a meridian of the links. This result is known as the meridian lemma for
alternating links. We give a meridian lemma for the class of fully alternating
links in the thickened orientable surfaces of positive genus.
