Possibility for entomophilous pollination on the climatically extreme and species-poor sub-Antarctic Marion Island

These three datasets were used to create a clear plant-invertebrate interaction network for Marion Island, between 11 plant species and the observed invertebrate species. This was done through both invertebrate visitation to plant species but also via including pollen data (obtained from the invertebrate specimens; using scanning electron microscopy). Additionally, environmental data was collected during 10-minute plant observations, which was then used to study the effect of these environmental variables (e.g., precipitation) on invertebrate abundance and richness on the 11 focal plant species (over two consecutive flowering seasons).

本研究共使用三套数据集，用于构建马里恩岛（Marion Island）上11种植物与观测到的无脊椎动物物种间的清晰植物-无脊椎动物互作网络。该网络的构建同时依托两方面数据：一是无脊椎动物的访植行为记录，二是通过扫描电子显微镜（scanning electron microscopy）从无脊椎动物标本中提取的花粉数据。此外，研究人员在10分钟的植物观测流程中采集了环境数据，随后利用这些数据探究降水等环境变量对11种目标植物上的无脊椎动物丰度与物种丰富度的影响，观测周期覆盖两个连续的开花季。
