| The differences in the size of adults inversely reflect the differences observed in the movement rates of ecotypes and populations. |
| However, for the general public, the caribou ecotypes are all the same, and a caribou is still a caribou. |
| To study the genealogical relationship among the ecotypes, we apply the theory of coalescence processes in the following way. |
| The need to use ecotypes for caribou conservation is another unique characteristic of this type of cervid. |
| It was assumed that factors that are under photoperiodic control would show a clinal order among the ecotypes. |
| For all wild and crop species tested, significant differences existed among ecotypes and varieties. |
