蜘蛛竞争长期以来一直是生态研究中难以捉摸的现象。由于大多数蜘蛛都是多面性捕食者，因此预计它们在空间使用和活动时段重叠的任何地方都会在资源使用上重叠。然而，尽管存在明显的竞争潜力，但竞争的实证证据却很薄弱。蜘蛛竞争可能会限制农业生态系统的密度，从而限制它们作为生物防治剂的有效性。我们总结了对一种生态系统（即湿地）的五项研究结果，这种生态系统在植被的面貌和周期性扰动状况方面都可以被认为类似于中耕作物。此外，我们总结了我们自己在大豆生态系统中的工作成果。
Spider competition has long been an elusive phenomenon for ecological study. Because most spiders are generalist predators, they are predicted to overlap in resource use wherever they overlap in space use and activity periods. However, despite this obvious potential for competition, the empirical evidence for competition has been weak. Spider competition could potentially limit densities in agricultural ecosystems, which would limit their effectiveness as biological control agents. We summarize the results of five studies in a type of ecosystem which may be considered to be analogous to row crops in both the physiognomy of vegetation and cyclic disturbance regimes, namely, wetlands. In addition, we summarize the results of our own work in a soybean ecosystem.
