Identifying declining and threatened species with museum data

摘要: Methods for inferring threat from scientific collections were tested using museum records of marsupials and monotremes in south-west Western Australia. A modification Solow's equation is presented that accounts changes collection effort. runs test, sensitive to zeroes anywhere the record, was only marginally useful identifying declining threatened species. The two forms equation, a trend analysis based on rank correlation, partial account effort, appeared most promising methods tested. results demonstrated use these infer may be when expert opinion limited or not available. In conjunction with other relevant information, it appears can help prioritise species basis relative levels threat.
