Query: Absence of Detailed Balance in Ecology   Living systems are typically characterized by irreversible processes. A
condition equivalent to the reversibility is the detailed balance, whose
absence is an obstacle for analytically solving ecological models. We revisit a
promising model with an elegant field-theoretic analytic solution and show that
the theoretical analysis is invalid because of an implicit assumption of
detailed balance. A signature of the difficulties is evident in the
inconsistencies appearing in the many-point correlation functions and in the
analytical formula for the species area relationship.
