This chapter illustrates using simulations how the assumed Janzen-Connell relationship between distance from parent and seed density can break down. Emphasis is given on spatial patterns of seed dispersal, the resultant spatial structure of seeds and the potential consequences for the population and the community. A special form of dispersal limitation is detailed, i.e. contagious seed dispersal, which is defined as the patchy deposition of seeds such that some sites receive many seeds and others receive few to none. By investigating contagious seed dispersal, the effects of spatial variability in seed dispersal curves on subsequent demographic processes are examined. The chapter explains where such dispersal is likely to take place and suggests potential outcomes for seed survival based on the resulting spatial deposition patterns. It illustrates how contagious seed dispersal relates to and modifies the original Janzen-Connell model and its community-level outcomes.
