Extensive global habitat degradation and the climate crisis are tipping the biosphere toward a "sixth" mass extinction and marine communities will not be spared from this catastrophic loss of biodiversity. The resilience of marine communities following large-scale disturbances or extinction events is mediated by the life-history traits of species and their interplay within communities. The presence and abundance of traits in communities provide proxies of function, but whether the breakdown of their associations with species loss can delineate functional loss remains unclear. Here, we propose that relationships between traits within trait networks provide unique perspectives on the importance of specific traits, trait combinations, and their role in supporting the stability of communities, while exploring the vulnerability of both past deep time and present-day marine communities.
全球范围内广泛的栖息地退化和气候危机正使生物圈走向“第六次”大灭绝，海洋群落也无法幸免于这场生物多样性的灾难性损失。大规模干扰或灭绝事件后海洋群落的恢复力由物种的生活史特征及其在群落中的相互作用介导。群落中特征的存在和丰度提供了功能的指标，但它们与物种丧失的关联破裂是否能界定功能丧失仍不清楚。在此，我们提出，特征网络内特征之间的关系为特定特征、特征组合的重要性及其在支持群落稳定性中的作用提供了独特视角，同时探索过去漫长时间和当今海洋群落的脆弱性。
