Human pressure in the oceans is pervasive and affects marine life. Understanding species' differing responses to human pressure, and how human pressure compares to other environmental variables in shaping marine communities is needed to facilitate the sustainable management of the seas. Despite theory and empirical evidence that fishing pressure affects marine life-history strategies, several recent large-scale studies have not shown strong relationships between fishing pressure and community composition. We aim to reconcile theory with data and explain these variable findings, testing the hypothesis that the signal of the effect of fishing pressure on marine communities depends on the scale at which the community is defined.

在更大的空间尺度上，捕捞压力对群落生活史特征的影响增加

海洋中的人类压力是普遍存在的，并影响着海洋生物。为了促进海洋的可持续管理，需要了解物种对人类压力的不同反应，以及人类压力与其他环境变量在塑造海洋群落方面的比较。尽管理论和经验证据表明捕捞压力影响海洋生物历史策略，但最近的几项大规模研究并未表明捕捞压力与群落组成之间存在密切关系。我们的目标是使理论与数据相一致，并解释这些可变的发现，检验捕捞压力对海洋群落影响的信号取决于群落定义规模的假设。
