The model examines the relationship between coextinction levels (proportion of species extinct) of affiliates and their hosts across a wide range of coevolved interspecific systems: pollinating Ficus wasps and Ficus, parasites and their hosts, butterflies and their larval host plants, and ant butterflies and their host ants. Applying a nomographic method based on mean host specificity (number of host species per affiliate species), we estimate that 6300 affiliate species are &quot;coendangered&quot; with host species currently listed as endangered. Current extinction estimates need to be recalibrated by taking species coextinctions into account.</style></abstract><issue><style face="normal" font="default" size="100%">5690</style></issue><accession-num><style face="normal" font="default" size="100%">44701</style></accession-num><notes><style face="normal" font="default" size="100%">LR: 20041117; JID: 0404511; ppublish1095-9203Journal</style></notes></record></records></xml>
