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 each....
