AbstractMost plants regenerate by seed bank. Animal activities affect seed fate from their departure from the parent plants to the establishment of seedlings. Animals play dual roles in plant regeneration , including consuming seeds and dispersing seeds to suitable sites for seedling recruitment . These two roles are trade-off . Studying the relationship between plant regeneration and animals will help to understand population dynamics , coevolution between animals and plants , community succession , the role of animals in ecosystem function and biodiversity. In recent studies , oaks and pines have been extensively studied species. It is well known that rodents and birds are the chief predators and dispersers for large seeds.
