虽然博物馆凭单标本仍然是物种鉴定的标准，但生物多样性数据越来越多地由相机陷阱和业余博物学家的照片记录来代表。有些物种在这些图片中很容易识别，有些则无法区分。在这里，我们量化了335种陆生非变异的北美哺乳动物在典型照片中可以识别的程度，有和没有考虑物种范围图。我们评估了所有物种的两两比较，并根据专业意见，判断它们在相机陷阱或iNaturalist众包平台的典型照片中是否在视觉上可区分，分为4个等级：(1)总是，(2)通常，(3)很少，或(4)从不。在55,944个成对比较中，大多数（96.5%）在一张照片中被评为总是或通常可区分的，剩下的2000对物种很少或永远无法从典型照片中区分出来，主要是在进化分支中，如鼩鼱和小体啮齿动物。考虑到物种的地理范围，消除了许多有问题的比较，例如，考虑到所有物种，任何地点难以区分或无法区分的物种对的平均数量是7.3对，而仅考虑那些通常用相机陷阱调查的物种对的平均数量是0.37对。难以区分的物种多样性最大的是亚利桑那州和新墨西哥州，有57对难以区分的物种，这表明问题的规模与整体物种多样性有关。我们的研究结果表明，哪些物种最容易通过摄影数据进行区分，哪些分类群应该在更高的分类水平（如属）上进行识别。我们的研究结果与生态学家以及那些使用人工智能识别照片中物种的人有关，但也提醒人们，通过博物馆代金券继续研究哺乳动物是至关重要的，因为这是准确识别许多较小物种的唯一途径，提供了从照片中无法获得的丰富数据，并通过精确的范围地图限制了照片记录。随着物种范围的变化，除了照片之外，正在进行的标本凭证收集将变得更加重要，而仅凭照片证据不足以记录许多物种的这些动态。
While museum voucher specimens continue to be the standard for species identifications, biodiversity data are increasingly represented by photographic records from camera traps and amateur naturalists. Some species are easily recognized in these pictures, others are impossible to distinguish. Here we quantify the extent to which 335 terrestrial nonvolant North American mammals can be identified in typical photographs, with and without considering species range maps. We evaluated all pairwise comparisons of species and judged, based on professional opinion, whether they are visually distinguishable in typical pictures from camera traps or the iNaturalist crowdsourced platform on a 4-point scale: (1) always, (2) usually, (3) rarely, or (4) never. Most (96.5%) of the 55,944 pairwise comparisons were ranked as always or usually distinguishable in a photograph, leaving exactly 2,000 pairs of species that can rarely or never be distinguished from typical pictures, primarily within clades such as shrews and small-bodied rodents. Accounting for a species geographic range eliminates many problematic comparisons, such that the average number of difficult or impossible-to-distinguish species pairs from any location was 7.3 when considering all species, or 0.37 when considering only those typically surveyed with camera traps. The greatest diversity of difficult-to-distinguish species was in Arizona and New Mexico, with 57 difficult pairs of species, suggesting the problem scales with overall species diversity. Our results show which species are most readily differentiated by photographic data and which taxa should be identified only to higher taxonomic levels (e.g., genus). Our results are relevant to ecologists, as well as those using artificial intelligence to identify species in photographs, but also serve as a reminder that continued study of mammals through museum vouchers is critical since it is the only way to accurately identify many smaller species, provides a wealth of data unattainable from photographs, and constrains photographic records via accurate range maps. Ongoing specimen voucher collection, in addition to photographs, will become even more important as species ranges change, and photographic evidence alone will not be sufficient to document these dynamics for many species.
