Moving uphill
A study in Science (June 2008, Vol 320, No 5884) shows that plants are relocating to higher altitudes to escape warming temperatures. The study found new generations thriving at higher altitudes and dying out at lower ones, leading to a shift in the population, at an average rate of 29 metres per decade. Because the shift is generational, plants associated with shorter life spans are making the move faster than bushes and trees. Other studies show that in Costa Rica, agronomists find coffee plants thrive at high-altitudes, which have never been found there before. In Kenya, mosquitoes are seeking cooler environments.
