Can pollination niches facilitate plant coexistence?

摘要: The question of why there are so many plant species needs two kinds answer: an explanation for the origin species, and how they can coexist. Pollinators often implicated in because adaptation to different modes pollination drive divergence floral traits bring about reproductive isolation. However, very few studies have attempted answer next question: ‘Can that differ only their mode coexist?' Fragmentary evidence supports idea intraspecific competition resources limit population growth rate, thus allowing coexistence use pollinators, or same pollinators at times.
