The Collection of Frozen Tissues has its origins tied to the growth of the Collection of Mammals in the 1980s under the direction of Dr. Mark Engstrom, who is now at the Royal Ontario Museum. Major growth continued after Dr. Robert Dowler became the curator in 1988.
The Collection of Frozen Tissues became recognized when Dr. Loren Ammerman arrived and assumed the role of curator, and she remains in that position today. Under her direction, the collection has accumulated more than 19,000 vouchered samples. The specimens are comprised primarily of mammals, but tissues of birds, reptiles and amphibians are also included. In addition to frozen tissues, the collection also maintains resources preserved in ethanol and lysis buffer.
Data for specimens in the Collection of Frozen Tissues is currently maintained within the other existing voucher databases: Mammalogy, Ornithology and Herpetology. Selected information from the database is searchable through our web interface. The data is searchable locally, but is also housed by GBIF, VertNet and iDigBio.
Although every effort is made to ensure the accuracy of catalog information, researchers should verify the information before use or publication. For additional information not provided through the searchable web interface, or if you have questions, please contact the curator.
Use and Loan of Specimens
Requests for tissue loans should be made in writing to the curator of frozen tissues, Dr. Loren Ammerman. Destructive sampling requests will be considered by the curator. Please refer to the ASNHC Tissue Loan Policy regarding the information that should be included in a request.
