生态对策生态对策bionomic strategies生态对策(bionomi七strategies)昆虫在进化过程中,经自然选择获得的对不同生境的适应方式。美国皮亚恩卡(E.R.Pianka)于1970年最先提出r选择和K选择概念,用以描述生物种间的适合度(fi tness)差异。适合度是指生物物种在某种环境条件下适应性的大小,并称之为生态对策或生活史对策(life history strategies),即每种生物都有其独特的个体大小、寿命或世代长短、出生率、存活率、迁移率等生态特征。生物对环境的适应涉及能量分配和时间分配。生物间能量分配可促进其适合度的法则被称为“分配原则”(the prineiple of alloeation),这是由进化过程抉择的而不是生物本身所能决定的。按照种群动态类型,可将生物的适合度划为两类:一类种群密度比较稳定、经常处于环境容纳量水平,称为K选择的(K一selected),属于这类的生物称为K对策者(K-strategists);另一类种群密度很不稳定、很少能达到环境容纳量水平,称为r选择的(r. selected),属于这类的生物称为r对策者(r- strategists)。在寄生性昆虫中,生态对策常被称为适应对策(adaPtive stra-tegies)。r和K两字母来源于表示种群增长的逻辑斯蒂方程中的两个参数,r为种群瞬时增长率,K为环境容纳量,均以繁殖表示种群适合度,故又称“繁殖对策”(reproduetive strategies)。r对策者和K对策者是进化方向不同的两个类型,其间还有多种过渡类型,构成一个r一K连续统份K continum)。在不同环境中产生不同生态对策的一系列因果关系,可作图解示意(图1和图2): ┌──────┐ │一众多,幼小│┌────────┐ └──────┘│非密度制约和不确│ │定的幼期包括卵、│ │动虫、蛹死亡率 │ └────────┘┌───────┐│种群变动: ││重组群体机会 │└───────┘ ┌────────┐┌───────┐│非密度制约和││高繁殖力 ││不确定的成虫││早成熟││死亡率 ││ │└────────┘└───────┘图1在r选择环境中产生r选择个体的一系列因果关系 (仿HS.Horn)昆虫种类繁多,具复杂的变态,主要摄食期是在幼虫期,幼虫期的生境特点几乎左右着物种对策。如热带的闪蝶个体大、寿命长、种群稳定、具有领域性,这些特征使它们位于r一K连续统的K选择一端。
