摘要: 大多数植物靠种子库来更新。种子从离开母体到建成幼苗的过程中始终受动物活动的影响。动物对种子既有取食消耗的不利一面,又有将其扩散到适于发芽的安全地点的有利一面,二者处于一种利弊权衡状态。研究动物与植物种子更新的关系,有助于揭示种群动态的机制,理解动物和植物之间协同进化的规律,了解生态系统演替及其组分之间的关系,认识取食种子的动物在生态系统中的作用,进而为生态系统维持和生物多样性保护提供科学依据及有效措施。目前对动物与森林更新关系的研究主要以栎、松等代表树种为研究对象。已知鼠类和鸟类是大型种子主要的捕食者和扩散者。

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.
