| Further research using this approach in the high southern latitudes is underway. |
| Here in the temperate northern latitudes trees have adapted over eons of regular annual seasons. |
| As warmth gradually returns to the northern temperate latitudes, so do the birds that migrated south last autumn. |
| As a result, there is much less interaction between the lower troposphere air masses of the polar regions and middle latitudes. |
| Broad environmental conditions, particularly average temperatures, differ less among populations in equatorial regions than at higher latitudes. |
| They are found in all seas, at all latitudes, and from the intertidal to the abyssal zone. |
