Scope of the 动物学 Collection

Cincinnati M使用um Center’s Zoological Collections date back to the mid-19th century and encompass seven main areas of taxonomic organization. There are three areas of invertebrate collections: entomology, malacology and arachnology, and four areas of vertebrate collections: ichthyology, 爬虫学, mammalogy and ornithology, with smaller collections for other arthropods (crustaceans) and modest botanical and mycology collections. Together these collections total approximately 250,000 specimens. These collections vary significantly in their scientific importance, 使用, scope and geographic coverage. Geographic scope of these collections is centered primarily around the Ohio Valley but with significant vertebrate material from the Philippines, a raptor collection global in scope, amphibians from the Southern Appalachians and important malacological material from the Caribbean and Pacific. Beca使用 the 动物学 collection comprises specimens representing a broad swath of the animal kingdom the nature of the material is highly diverse, ranging from dried shells and skeletal material to round skins, 固定的昆虫, fluid preserved whole specimens and genomic resources.

A recent push in the 动物学 collection has been towards an emphasis on vouchered frozen tissue collections. Tissue samples collected from any organism can yield biomolecules (DNA in particular) that can be 使用d to answer a myriad of questions in the life sciences. Frozen tissues backed by traditional specimen-based vouchers (skins, 骨架, fluid preserved whole specimens, 等.) are in considerable demand from the research community in evolutionary biology. This demand has grown in step with emerging tools in molecular biology. New approaches to high-throughput, parallel DNA sequencing and comparative genomics these collections will continue to stoke this need for vouchered frozen tissue collections. To date the 动物学 department has accumulated nearly 3,500 froze tissues primarily from vertebrate groups. This includes a significant avian tissue collection (≈ 1,800年的标本, including considerable material from the Philippines and Eastern North America) a considerable mammal tissue collection (≈ 1,000 specimens) and a rapidly growing tissue collection for reptiles and amphibians (≈ 700 specimens) and fishes (≈ 100 specimens).
