摘要

跨越环境梯度的过滤过程可以构建群落内的性状变异模式。群落加权平均值（CWM）是一个指标，通常用来表示这种过滤过程的方向性和群落内类群的最佳适应策略。接近群落加权平均值表示更高的适应性，偏离这一最佳值会导致共存物种的相对丰度发生变化。我们研究了四种共存腐肉甲虫（鞘翅目：蚕科）跨海拔梯度的种内性状变异模式。研究在海拔 950 米到 1700 米之间、具有不同自然植被带的温带森林生态系统中进行。在测量的12个性状中，我们发现种内变异从34%（体长）到100%（背长、头长和头宽与体长之比）不等，在7个性状中，种内变异所占比例大于种间变异。在大多数性状中，性状范围与相对丰度呈正相关，性状范围表示物种在特定海拔的生态位广度。与远距离扩散相关的性状的CWM随海拔升高而降低，而与微生境利用相关的性状的CWM则呈现相反的趋势。在控制了物种特征的影响后，土壤温度对胫骨长度有影响，但土壤含水量对性状变化没有影响。两个甲虫物种的体宽和胸宽的变异模式支持CWM-最优假说；然而，另一个物种的体宽和胸长的性状变异模式却呈现出相反的趋势。我们的研究发现了腐肉甲虫物种内部可能存在高度变异的几种性状。这种高水平的种内性状变异可能使种群能够适应各种海拔高度和植被类型。
