Query: Notes on reductions of superstring theory to bosonic string theory   It is in general very subtle to integrate over the odd moduli of super
Riemann surfaces in perturbative superstring computations. We study how these
subtleties go away in favorable cases, including the embedding of N=0 string to
N=1 string by Berkovits and Vafa, and the relation of the graviphoton amplitude
and the topological string amplitude by Antoniadis, Gava, Narain and Taylor and
Bershadsky, Cecotti, Ooguri and Vafa. The Poincar\'e dual of the moduli space
of Riemann surfaces in the moduli space of super Riemann surfaces plays an
important role.
