There is no standard for reporting faunal identifications in zooarchaeology. Zooarchaeologists are open to accusations that reported conclusions are invalid. Other sciences counter such problems through use of quality assurance, consisting of quality control (QC), and assessment (QA). QC is a standard for procedures adopted during laboratory practice. A rarely cited standard was published by Driver in 1992. QA focuses on criteria for faunal identification and is becoming more common in zooarchaeology. QC and QA must be integral parts of zooarchaeology if identifications are to be accepted. The stakes are high because paleobiological datasets are now used to study problems in conservation science.

Behavioral depression is a decline in prey availability because of enhanced alert response, movement away from areas, increased social behavior, and other responses to predators. This form of resource depression is an alternative hypothesis to be contrasted to over-exploitation that potentially explains a decrease in hunting efficiency over time should the zooarchaeologist observe a decline in the relative abundance of remains of high-rank prey. Gregarious ungulates, such as many North American cervids, may exhibit such behavioral responses under predation. The white-tailed deer ( Odocoileus virginianus), one of the most common high-rank prey animals from Holocene archaeological sites in eastern North America, is less gregarious, more r-selected, and exhibits greater home-range fidelity than other cervids. As a result, whitetails are less likely to exhibit behavioral depression than other North American ungulates, which may explain their common occurrence in Holocene archaeological faunas, such as that from the Eagle's Ridge site in southeast Texas where resource depression appears to have occurred from 4,500 to 1,500 years ago. The behavioral ecology of ungulate species should be considered on a case-by-case basis to develop testable hypotheses about prehistoric human predation. [ABSTRACT FROM AUTHOR]
