Abstract

It is generally assumed that morphological structures like awns, bristles, or hooks increase retention potential of plant diaspores to the coats of animals, but this basic assumption has rarely been tested. In this paper we introduce a lab-experiment in which detachment rates of diaspores from mechanically shaken animal coats are measured using a standardized protocol and compared with ...
