The abundance of diaspores also showed a seasonal variation which depended on the dispersalagent. However, cedar waxwings could be a better dispersalagent than gray silky-flycatchers because of their gregarious behaviour and abundance during the mistletoe fruit season. They are opportunistic feeders and now feed on sooty tern eggs, turtle eggs and fruits of invasive species, acting as a dispersalagent.

The monito del monte is the single dispersalagent for this plant, and without it the plant would likely become extinct.

Furthermore, the availability of propagules and dispersal agents throughout the year ensures the structural re-establishment of the vegetation following disturbance. Adaption of fruit morphology to dispersal agents in a neotropical forest. Adaptation of fruit morphology to dispersal agents in a neotropical forest. In the absence of dispersal agents a recolonization front is created, whose dynamics depends on the maturation of saplings. Temporally aggregated fruiting may also be favoured when few extra-generic species are fruiting or when the effectiveness of shared dispersal agents varies seasonally. In our case, 86% of seeds survived the passage through the gut of the dispersal agents. Production and consumption of fruits, dispersal agents, feeding behaviour, transport and effects on seed viability, were investigated by field observations, cage experiments and viability tests. Also, as dispersal agents are adversely affected, community composition and species richness will be altered. A recent reduction in population or efficacy of seed dispersal agents could explain the observed results. These hypotheses can be tested by studying the abundance and diet of dispersal agents as they feed on sympatric plants exhibiting different fruiting phenologies. Alternatively, selection may favour temporally aggregated fruiting phenologies when the effectiveness of seed dispersal agents varies seasonally or when large, synchronous fruit displays enhance dispersal. Scatter-hoarding behavior depends on jays and squirrels associating with plants that provide good packets of food that are nutritionally valuable, but not too big for the dispersalagent to handle.

Selection may favour temporally segregated fruiting phenologies to minimize this competition and also to maintain resident populations of dispersal agents. These evolutionary scenarios assume that plants share seed dispersal agents. These examples are from corpora and from sources on the web.
