二叠纪-三叠纪过渡期是陆地生态系统演化史上的一个关键时期。然而，由于缺乏化石记录，人们对这一时期陆地生态系统的生态基础知之甚少。在生命史上，研究较少的事件之一是二叠纪-三叠纪生态危机之前陆地生态系统的生态状态。通过对西南地区二叠系最上部1086个植物标本的植物区系组合及其植食性昆虫危害的定量研究，探讨了这一问题。这一大型植物群包括25属36种植物，代表了上二叠统典型的热带雨林植被。我们记录了171个昆虫损害的发生属于24个独特的损害类型（DT）从6个功能性摄食组，被公认的植物群。通过对该植物群中DT的出现频率、丰富度、多样性和频率的统计分析，表明羊齿蕨类植物是食草昆虫的主要寄主植物。与其他晚二叠世植物群相比，根据植物地理区的全球位置，可以在古纬度上识别出昆虫危害谱的显著差异。尽管不同的，主要的目标植物宿主，在这些植物区系中，昆虫DT的丰富性和多样性和他们的植食性水平从中到高纬度的植物区系显着低于低纬度到赤道的植物区系。我们的研究表明，从低纬度的陆地生态系统具有较高的生态复杂性水平，和一个明显的纬度梯度，可能是很好地建立在陆地生态系统在晚二叠世。该评价首次对晚古生代华夏植物群的植物和昆虫之间的生态关系及其在陆地生态系统中的代表性进行了全面的综述。
The Permian–Triassic transition is concerned with a critical time interval during the evolutionary history of terrestrial ecosystems. However, the ecological underpinnings of terrestrial ecosystems during this time interval are poorly understood due to an impoverished fossil record. One of the more understudied episodes in the history of life is the ecological state of terrestrial ecosystems immediately before the Permian–Triassic ecological crisis. We address this issue by a quantitative study of a floral assemblage and its herbivorous insect damage based on 1086 plant specimens from the uppermost Permian of Southwest China. This bulk flora comprises 25 genera and 36 species of plants representing a typical, tropical rainforest vegetation of the upper Permian. We record 171 insect damage occurrences belonging to 24 distinctive damage types (DTs) from six functional feeding groups that were recognised in the flora. Statistical analyses of the occurrence, richness, diversity and frequency of DTs reveal that gigantopterids are the principal host plants for insect herbivores in the flora. Compared with other late Permian floras, a significant distinction of the insect damage spectrum can be recognised palaeolatitudinally based on the global position of phytogeographic regions. Despite the different, major targeted plant hosts in these floras, the richness and diversity of insect DTs and their herbivory levels from mid- to high latitudinal floras are remarkably lower than those of low latitudinal to equatorial floras. Our study indicates that terrestrial ecosystems from lower latitudes have higher levels of ecological complexity, and a distinct latitudinal gradient that probably was well established in terrestrial ecosystems during the late Permian. This assessment provides the first comprehensive overview of the ecological relationships among plants and insects, as well as their representation in terrestrial ecosystems of the late Paleozoic Cathaysia Flora.
