Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites ...
The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy berries may not successfully reach such elusive regeneration microsites. Ericace...

The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity.

Ericaceous, berry-producing species in the northern hemisphere demonstrate this dispersal limitation. They are said to display a reproductive paradox owing to their lack of regeneration in apparently suitable microsites despite considerable investment in producing large quantities of berries. Cadavers generate vegetation-denuded and nutrient-rich disturbances termed cadaver decomposition islands. Cadavers attract facultative scavengers with considerable capacity for endozoochorous seed dispersal.
