Abstract
Seed production is one of the most basic and important ecosystem processes because it provides the continuous renewal of green biomass. Most flowering plants produce seeds through pollination interactions with animals, and therefore this interaction is crucial for ecosystem diversity, stability and resilience to disturbance. Currently, there is growing awareness of a pollination crisis whereby the diversity of pollinators is declined due to human interference. If real, this decline may have cascading effects on plant population dynamics and ultimately on ecosystem diversity and function. To truly assess any consequences of a pollination crisis for natural ecosystems, there is an urgent need for more substantial and complete knowledge of plant-pollinator relationships and interactions, and the consequences of such interactions for the population dynamics of plants.
