Zusammenfassung: | Accuracy of age determination in Coyotes (Canis latrans ) from tooth-wear patterns was compared to that from cementum annuli of first premolars and canines. Age determined from first premolar and canine sections agreed in 14 of 19 specimens. Although the use of canine teeth is preferred because of better definition of lines, first premolars and canines from the same animal differed by only one or two annuli. Thus first premolars may be used to determine age when extraction of a canine is not feasible. Tooth-wear patterns reliably gave the age of pups and yearlings only. In older Coyotes this method generally underestimated age by about one or two years. |
