植物和昆虫在陆地生态系统中相互作用已有数百万年的历史，对食物网的功能至关重要。这些相互作用可以根据不同的功能取食群和危害类型进行分类，并提供有关植物和昆虫之间关系的信息。我们的研究重点是法国南部的贝纳索(Herault)的更新世沉积。贝纳索化石叶组合的年龄为2.16-1.96 Ma，对应于一个由大陆和地中海物种组成的落叶森林，如Carpinus orientalis Mill.、Parrotia persica C.A.Mey。和蒙山枫L、家养花椒L。590个化石叶片代表了20个不同的植物物种，其中超过36%的化石叶片存在虫害。共发现39种不同的损伤类型，其中以咬伤最为突出。这些类型的相互作用使人们能够讨论在这一时期盛行的生态环境(林龄、降水、温度)。例如，该地区的年平均降水量肯定高于今天。此外，本研究的结果也为生态古森林群落的研究提供了新的思路。(C)2016爱思唯尔B.V.保留所有权利。
Plants and insects have interacted for millions of years in terrestrial ecosystems and are essential to the function of the food web. These interactions can be classified based on different functional feeding groups and damage types, and provide information about the relationship between plants and insects. We focused this study on the Pleistocene deposit of Bernasso (Herault, southern France). The Bernasso fossil leaf assemblage has been dated from 2.16-1.96 Ma and corresponds to a deciduous forest comprising both continental and Mediterranean species such as Carpinus orientalis Mill., Parrotia persica C.A. Mey. and Acer monspessulanum L, Sorbus domestica L, respectively. Twenty different plant species are represented by 590 fossil leaves among which more than 36% present insect damage. Thirty-nine different damage types were found with galling being the most prominent. These types of interactions enable discussion about the ecological settings that prevailed at this epoch (forest age, precipitation, temperature). For instance, the mean annual precipitation was certainly higher than today in the region. Moreover, the results of this study offer the possibility to get new insights into the ecological paleoforest community. (C) 2016 Elsevier B.V. All rights reserved.
