Query: Seasonal species interactions minimize the impact of species turnover on
  the likelihood of community persistence   Many of the observed species interactions embedded in ecological communities
are not permanent, but are characterized by temporal changes that are observed
along with abiotic and biotic variations. While work has been done describing
and quantifying these changes, little is known about their consequences for
species coexistence. Here, we investigate the extent to which changes of
species composition impacts the likelihood of persistence of the predator-prey
community in the highly seasonal Bialowieza Primeval Forest (NE Poland), and
the extent to which seasonal changes of species interactions (predator diet)
modulate the expected impact. This likelihood is estimated extending recent
developments on the study of structural stability in ecological communities. We
find that the observed species turnover strongly varies the likelihood of
community persistence between summer and winter. Importantly, we demonstrate
that the observed seasonal interaction changes minimize the variation in the
likelihood of persistence associated with species turnover across the year. We
find that these community dynamics can be explained as the coupling of
individual species to their environment by minimizing both the variation in
persistence conditions and the interaction changes between seasons. Our results
provide a homeostatic explanation for seasonal species interactions, and
suggest that monitoring the association of interactions changes with the level
of variation in community dynamics can provide a good indicator of the response
of species to environmental pressures.
