The relative importance of olfactory signaling to fly-moss spore dispersal network structure of two sympatric moss species in Newfoundland, Canada
In Newfoundland, Splachnum ampullaceum (herbivore dung scent mimic) and S. pensylvanicum (omnivore dung scent mimic) grow in bogs on summer moose (Alces alces L.) dung and via olfactory and visual deception have their spores dispersed to dung by flies. In Chapter 2, the addition of carnivore and her...
