Summary: | Mandibles from 270 moose harvested during 1988-1990 from the Seward Peninsula, Alaska were examined. Broken incisiform teeth were observed in 61% of 243 adult moose and 41% of 27 yearling moose examined. First incisors (I1) were the most frequently (48%) broken teeth in adults. All yearling moose had newly emerged I1’s and 60% had permanent 2nd incisors (I2) when killed, consequently because third incisors (I3) and canines were most frequently (35%, 9%) broken. Severity of tooth breakage was correlated (P<0.001) with age. All moose > 7 years-of-age had broken incisiform teeth. This level of incisiform tooth breakage has not been previously observed in North American moose. |
