生物多样性监测对于了解气候变化如何影响从单一物种到生物多样性空间分布的分类群分布至关重要。大规模和跨类群的生物多样性监测也允许跨类群的地理模式的经验性理解。其中一种模式是，在热带纬度的分类丰富度高峰通常被视为一种地理学规则，很少有明显的例外。在这里，我们利用北美国家生态观测网络（氖）的无脊椎动物陷阱收集来描述跨分类群和跨分类规模的地方分类丰富度的模式。重点介绍了节肢动物门、环节动物门和软体动物门。此外，我们使用专家鉴定的三个氖哨兵分类群（步甲科、蚊科和硬蜱科）样本估计了区域物种丰富度。为了对陷阱动物进行采样，我们过滤了储存乙醇，并采用环境DNA条形码方法来扩增和测序从滤液中提取的线粒体基因的两个区域的DNA。我们将这些序列与参考序列的相似性达到97%，并在种、属、科和目的水平上计算了当地的分类丰富度。我们计算了当地的物种丰富度为12种常见的无脊椎动物类群。我们使用广义线性模型来描述分类丰富度与空间，气候和丰度预测变量之间的关系。在四个分类尺度上，从种到目，分类丰富度随纬度的变化而显著增加。在我们研究的12个无脊椎动物类群中，有7个反映了物种丰富度的正纬度梯度。在区域尺度上，3个氖哨兵类群中有2个类群的物种丰富度呈现出正的纬度梯度。温度、降水量、丰度和序列读段数在解释分类丰富度模式中起次要作用。当考虑这些大多是温带网站，跨越46度的纬度，我们发现没有支持预期的负纬度梯度跨类群和分类尺度。相反，对于许多这些分类群和分类尺度，我们观察到显著的，正的丰富度梯度随着纬度的增加，在地面居住的无脊椎动物群落。因此，一个最“一般”的模式，在植物地理学没有发现大多数无脊椎动物类群横跨温带纬度。
Biodiversity monitoring is imperative for understanding how changing climate may impact the distributions of taxa from single species to the spatial distribution of biological diversity. Large‐scale and cross‐taxa biodiversity monitoring also allows an empirical understanding of biogeographic patterns across taxa. One such pattern, where in taxonomic richness peaks at tropical latitudes are typically treated as a biogeographical rule with few notable exceptions. Here we leveraged the invertebrate pitfall collections of the National Ecological Observatory Network (NEON) across North America to describe patterns of local taxonomic richness across taxa and across taxonomic scale. We focused on Arthropoda, Annelida and Mollusca. Additionally, we estimated regional species richness using expert‐identified samples of three NEON sentinel taxa: Carabidae, Culicidae and Ixodida. To sample pitfall animals, we filtered storage ethanol and employed environmental DNA‐barcoding methodologies to amplify and sequence extracted DNA from the filtrate for two regions of a mitochondrial gene. We assigned taxonomic names to these sequences at 97% similarity to reference sequences and calculated local taxonomic richness at the levels of species, genus, family and order. We calculated local species richness for 12 common invertebrate taxa. We used generalized linear models to describe the relationships between taxonomic richness and spatial, climatic and abundance predictor variables. At four taxonomic scales, ranging from species to order, taxonomic richnessincreased significantly as a function of latitude. Of the twelve invertebrate taxa weexamined, seven mirrored this positive latitudinal gradient in species richness. At theregional scale, two of three NEON Sentinel Taxa showed positive latitudinal gradientsin species richness. Temperature, precipitation, abundance and sequence read numberplayed minor roles in explaining patterns of taxonomic richness. When considering these mostly temperate sites that span 46 degrees of latitude, we found no support for the expected negative latitudinal gradients across taxa and taxonomic scales. Instead, for many of these taxa and taxonomic scales, we observed significant, positive richness gradients with increasing latitude among ground‐dwelling invertebrate communities. Thus, one of the most ‘general' patterns in biogeography was not found for most invertebrate taxa across temperate latitudes.
