种群是什么意思？

· 基本释义

也叫群体。同种生物在特定环境空间内和特定时间内的所有个体的集群。能自由交配、繁殖。种群反映生物个体所不具备的特征，包括密度、年龄及性别比率、出生和死亡率、迁入和迁出率、种内和种间的相互关系。动物种群还具有占有领地、迁徙活动和社会行为等特征。种群在分类学、遗传学、生态学研究中都是基本单位。

· 网络释义

种群（population）指在一定时间内占据一定空间的同种生物的所有个体。种群中的个体并不是机械地集合在一起，而是彼此可以交配，并通过繁殖将各自的基因传给后代。种群是进化的基本单位，同一种群的所有生物共用一个基因库。对种群的研究主要是其数量变化与种内关系，种间关系的内容已属于生物群落的研究范畴。种群与群落不是相同概念
