Terrestrial predators play key roles in cycling nutrients, as well as limiting prey populations, and shaping the behaviour of their prey. Prehistoric, historic and ongoing declines of the world's predators have reshaped terrestrial ecosystems and are a topic of conservation concern. However, the availability of ecologically relevant predator functional traits is limited, hampering efforts to understand macroecological changes in this ecologically important functional group. Here, we present CarniTraits, a comprehensive open-access functional trait database of all late Quaternary (~130,000 ybp) terrestrial mammalian predators (149 species, ≥1 kg body mass, ≥50% vertebrate meat consumption).

世界晚第四纪陆生哺乳动物捕食者的功能特征


陆生捕食者在循环营养物质、限制猎物种群和塑造猎物的行为方面发挥着关键作用。世界捕食者的史前、历史和持续减少已经重塑了陆地生态系统，是一个值得关注的保护话题。然而，与生态相关的捕食者功能特征的可用性是有限的，阻碍了了解这一生态重要功能群的宏观生态变化的努力。在这里，我们介绍了 CarniTraits，这是一个全面的开放获取功能性状数据库，包含所有晚第四纪（~130,000 ybp）陆生哺乳动物捕食者（149 个物种，≥1 公斤体重，≥50% 的脊椎动物肉消费）。
