Age-specific growth and remarkable longevity in narwhals (Monodon monoceros) from West Greenland as estimated by aspartic acid racemization / Eva Garde, Mads Peter Heide-Jørgensen, Steen H. Hansen, Gösta Nachman, Mads C. Forchhammer.
Title: | Age-specific growth and remarkable longevity in narwhals (Monodon monoceros) from West Greenland as estimated by aspartic acid racemization / Eva Garde, Mads Peter Heide-Jørgensen, Steen H. Hansen, Gösta Nachman, Mads C. Forchhammer. |
Author(s): | Garde, Eva. Heide-Jørgensen, Mads Peter. Hansen, Steen H. Nachman, Gösta. Forchhammer, Mads C. |
Date: | 2007. |
In: | Journal of Mammalogy. (2007.), Vol. 88(1) (2007) |
Abstract: | Reports estimation of age of narwhals (Monodon monoceros) from eyes collected from 75 specimens in west Greenland in 1993 and 2004. Age estimates are based on racemization of L-aspartic acid to D-aspartic acid in nucleus of eye lens. Using Bertalanffy growth model, estimates age at sexual maturity to be 6-7 years for females and 9 years for males. |
