Datasets used in analysis of "Forest vertical and horizontal temperature similarity drives arthropod communities in a managed temperate forest"

we set up temperature loggers and insect traps vertically (flight-interception traps) and horizontally (pitfall traps) in forests with experimental thinning and gap felling 8 years after the intervention. By metabarcoding, we identified ~10,600 Operational Taxonomic Units (OTUs) from 44 orders including ~2450 arthropods assigned to species in our 426 samples. Arthropod community similarity matrices were quantified along the Hill numbers accounting for rare to dominant species and under consideration of incomplete samples.Dataset "ns2025-04_Mueller_EC24-339-and-343_comb_COI_results" contains all recovered OTU species;Dataset "sp_matrix_arthropods" contains recovered OTU species limited to terrestrial arthropods;Dataset "env_finascale_final" contains environemntal variables including temperature metrics of each arthropod trap.<br>

本研究于实验疏伐与林隙采伐措施实施8年后的森林样地内，布设温度记录仪，并垂直搭建飞行拦截陷阱（flight-interception traps）、水平搭建巴氏陷阱（pitfall traps）作为昆虫诱捕装置。通过元条形码（metabarcoding）技术，本研究在426份样本中成功鉴定出隶属于44个目的约10600个操作分类单元（Operational Taxonomic Units，OTU），其中约2450个节肢动物（arthropods）被归类为已知物种。本研究基于Hill数（Hill numbers）对节肢动物群落相似性矩阵进行量化，该方法兼顾稀有物种至优势物种的丰度梯度，并充分考虑了样本不完全性的影响。数据集"ns2025-04_Mueller_EC24-339-and-343_comb_COI_results"包含所有已获取的OTU物种；数据集"sp_matrix_arthropods"包含仅限定于陆生节肢动物的已获取OTU物种；数据集"env_finascale_final"包含各类环境变量，其中涵盖每台节肢动物诱捕装置的温度监测指标。
