How far can the freshwater bryozoan Cristatella mucedo disperse in duck guts?

Statoblasts of Cristatella mucedo were fed to two duck species, pintail (Anas acuta ) and shoveler (A. clypeata ), to assess whether endozoochorous dispersal is responsible for the metapopulation structure of this bryozoan. Eight individuals (four per duck species) were force-fed 500 statoblasts eac...
