由于移植实验表明，在物种范围范围内，性能通常会下降，因此一些范围限制可能是由于阻止适应压力环境的因素和过程而产生的。在这里，我们确定了植物防御的生态成本，包括与当地植物群落变化相关的胁迫，是否有助于旱地芥菜物种Boechera stricta的范围限制发育。在499株严格螺旋藻的普通园林试验中，群落性能下降，群落结构的多元轴在边界上增加，表明应力增加与群落变化有关。标记推断的缢蛏自交系对逆境的耐受性也存在显著的遗传变异（进化潜力）；然而，高基础水平硫代葡萄糖苷毒素的品系对群落结构变化的耐受性较低。我们认为，在整个范围内也需要防御分配，这可能阻碍了对与社区变化相关的压力的适应，从而有助于范围限制的发展。
Because transplant experiments show that performance usually decreases across species range boundaries, some range limits might develop from factors and processes that prevent adaptation to stressful environments. Here, we determined whether an ecological cost of plant defense involving stress associated with changes in the local plant community may contribute to range limit development in the upland mustard species Boechera stricta. In a common garden experiment of 499 B. stricta plants, performance decreased and a multivariate axis of community structure increased across the boundary, indicating increased stress associated with the community change. There was also significant genetic variation (evolutionary potential) among marker-inferred inbred lines of B. stricta for tolerance to the stress; however, lines with high basal levels of glucosinolate toxins had lower tolerance to the change in community structure. We suggest that defense allocation, which is also needed across the range, may impede adaptation to the stress associated with the community change and thus contribute to range limit development.
