摘要
随着全球环境破坏的加剧,物种丧失的速度加快,人们日益关注生物多样性的保护。种群生物学和自然保护生物学的一些研究表明,如果一个局域种群受到Allee效应的影响,最终可能走向灭绝。从物种保护的角度考虑,分别介绍了集合种群水平上的Allee效应的和似Allee效应,比较了集合种群的Allee效应和似Allee效应产生的原因,以及集合种群的Allee效应和局域种群的Allee效应之间的关系、集合种群的似Allee效应和局域种群的Allee效应之间的关系,并提出集合种群的Allee效应还需要进一步的研究。
As the global environment is destroyed more seriously and the rate of species lost becomes faster, people payed more attention to the protection of biodiversity. Some studies on population biology and science protection biology indicted that if a local population influenced by Allee effects would be extinct finally. Taking the protection of biodiversity into account, the Allee effects and Allee-like effects of metapopulation were separately introduced. The reasons of metapopulation＇s Allee effects arising and the relationships with local population＇s Allee effects were compared.
