Growth studies in the reindeer (Rangifer tarandus) : with an analysis of population changes in the Mackenzie Delta herd over the period 1938-1958
A study of the growth of reindeer (Rangifer tarandus) was carried out during the spring and summer of 1958 in the Mackenzie Delta, N.W.T. Growth rates were obtained for four fawns over this period. Their growth is described by Brody's equation and the von Bertalanffy equation. The rate of growt...
