NEON Biorepository Carabid Collection (Trap Sorting)

<p>This collection contains subsamples of Carabid adults from pitfall sampling from a single trap (NEON sample class: bet_sorting_in.subsampleID.bet). Ground beetles are sampled using pitfall traps (16 oz deli containers filled with 150 or 250 mL of propylene glycol). Four (pre-2018) or 3 (2018 and beyond) traps are deployed in each of 10 (pre-2023) or 6 (2023 and beyond) plots at each terrestrial NEON site, with traps arrayed approximately 20 meters from the center of the plot. Sampling occurs biweekly throughout the growing season (when temperatures are above 4 degrees C). Following trap collection, all beetles from the family Carabidae are sorted by NEON technicians and identified to species or morphospecies. A subset of collected Carabidae are pointed or pinned, while other specimens (non-pinned/non-pointed carabids, invertebrate bycatch, and vertebrate bycatch) are stored in 95% ethanol for archiving. Regardless of storage method, all collections data are reported at a per trap resolution. A subset of pinned ground beetles (up to 467 per site per year) are sent to an expert taxonomist for secondary identification. Identifications performed on these individuals may be used to estimate uncertainty in parataxonomist identification by NEON technicians.

本数据集收录了来自单个陷阱（NEON样本类别：bet_sorting_in.subsampleID.bet）的土栖甲虫成虫子样本。通过陷阱法（16盎司熟食容器填充150或250毫升丙二醇）进行地面甲虫的采集。在每个陆地NEON观测点，于每个10（2023年之前）或6（2023年之后）个样地中部署4（2018年之前）或3（2018年之后）个陷阱，陷阱位置位于样地中心约20米处。采样活动在生长季节内（气温高于4摄氏度时）每两周进行一次。在陷阱收集之后，NEON技术人员对所有属于鞘翅目甲虫的个体进行分类，并鉴定至物种或形态物种水平。收集到的部分鞘翅目甲虫被标记或固定，而其他样本（非固定的/非标记的甲虫、无脊椎动物误捕物和脊椎动物误捕物）则存储在95%乙醇中以便存档。无论采用何种存储方式，所有采集数据均以每个陷阱的分辨率进行报告。每年每个观测点（最多467个）的固定地面甲虫子样本被送往专家分类学家进行二次鉴定。对这些个体的鉴定结果可用于估计NEON技术人员在辅助分类学家鉴定中的不确定性。下方的相关链接提供了操作规程和NEON相关数据产品。
