Nature would select those snakes that blend in w/the desert Monday August 27th 2018 In temperate deciduous forests, snakes can come in all sizes and colors. Recent studies into global climate change are showing that temp. forests closer to the equator are at greater risk of “ecological shift” (when one ecosystem becomes another). Scientists predict that 500 years from now (2018) temp. forests, especially those in India, China and the Middle East could shift into desert ecosystems. Based on this information given…what do you think the population of snakes would look like in 1,000 years if an ecological shift took place?
