Seasonal dynamics of a complex cheilostome bryozoan symbiosis: vertical transfer challenged
Abstract Symbiotic associations are dynamic systems influenced by both intrinsic and extrinsic factors. Here we describe for the first time the developmental and seasonal changes of the funicular bodies in the bryozoan Dendrobeania fruticosa, which are unique temporary organs of cheilostome bryozoan...

Abstract Symbiotic associations are dynamic systems influenced by both intrinsic and extrinsic factors.
