Michigan Fish Atlas

Point locations for collections of Michigan fish The data set was created to facilitate production of point maps showing distributions of fish in Michigan, both historical and current. The data came from MDNR (approximately 63,000 records, 5000 sites, dating from 1923), UMMZ (35,000 records, 4700 sites, dating from 1874), United States Geological Survey, Great Lakes Science Center (USGS/GLSC) (34,000 records, 4600 sites, dating from 1958), United States Fish and Wildlife Service (USFWS) (33,000 records, 4100 sites, dating from 1947), Michigan River Inventory (MRI) (8000 records, 546 sites, dating from 1937). University of Michigan Center for Great Lakes and Aquatic Science (UM/CGLS) (1,400 records, 100 sites dating from 1982) and miscellaneous sources (600 records, 600 sites, dating from 1923). The MRI collections were made by Drs. Paul W. Seelbach, Michael J. Wiley and students from the UM School of Natural Resources and Environment combined with collections made mostly on large rivers by the MDNR. The UM (CGLS) collections were made by Dr. David Jude. Hybrids and unidentified species were excluded from all data sets. In the UMMZ collections, the identification of species has been painstakingly addressed and voucher specimens are available for amost all of the fish collections. However, in the other collections identification of species is accepted but, in most cases, no voucher specimens for verification of identity are available.密歇根鱼类采集点位数据集 本数据集旨在辅助制作展示密歇根州境内古今鱼类分布的点位分布图。本数据集的数据源自多个机构与渠道，具体包括：密歇根州自然资源部（Michigan Department of Natural Resources, MDNR，约63000条记录、5000个采集点位，采集时间可追溯至1923年）、密歇根大学动物学博物馆（UMMZ，35000条记录、4700个采集点位，采集始于1874年）、美国地质调查局大湖科学中心（United States Geological Survey, Great Lakes Science Center, USGS/GLSC，34000条记录、4600个采集点位，采集始于1958年）、美国鱼类及野生动物管理局（United States Fish and Wildlife Service, USFWS，33000条记录、4100个采集点位，采集始于1947年）、密歇根河流调查项目（Michigan River Inventory, MRI，8000条记录、546个采集点位，采集始于1937年）、密歇根大学大湖与水生科学中心（University of Michigan Center for Great Lakes and Aquatic Science, UM/CGLS，1400条记录、100个采集点位，采集始于1982年）以及其他杂项来源（600条记录、600个采集点位，采集时间可追溯至1923年）。密歇根河流调查项目（MRI）的标本由保罗·W·西尔巴赫（Paul W. Seelbach）博士、迈克尔·J·威利（Michael J. Wiley）博士以及密歇根大学自然资源与环境学院的学生完成采集，该部分采集工作与MDNR主要针对大型河流的采集任务相结合。密歇根大学大湖与水生科学中心（UM/CGLS）的标本采集工作由戴维·朱迪（David Jude）博士主持。所有数据集均已剔除杂交物种与未鉴定物种。在UMMZ的馆藏中，研究人员已对物种鉴定开展了严谨细致的校核工作，且几乎所有鱼类馆藏均配有凭证标本可供核验。但对于其余来源的馆藏，虽认可其出具的物种鉴定结果，但在多数情况下无对应凭证标本可用于身份验证。
