Canadian scientists say they have conducted the first experiment that shows the evolution of new species impacts the environment. Scientists at the University of British Columbia created mini-ecosystems in large aquatic tanks using different species of three-spine stickleback fish and saw substantial differences in the ecosystems within 11 weeks. Stickleback fish originated in the ocean, but began populating freshwater lakes and streams following the last ice age. The researchers said that...

Scientists have come to agree that different environments impact the evolution of new species. Now experiments conducted at the University of British Columbia are showing for the first time that the reverse is also true.Researchers from the UBC Biodiversity Research Centre created mini-ecosystems in large aquatic tanks using different species of three-spine stickleback fish and saw substantial differences in the ecosystems in as little as 11 weeks.Their findings are published in today's...

WASHINGTON -- More species develop in warm, tropical climates or cooler, temperate areas? It turns out the longtime answer - the tropics - may be wrong. True, more different types of animals exist there than in places farther from the equator. New research suggests that is because tropical species do not die out as readily. Cooler regions have a higher turnover rate, with more species developing but also more becoming extinct. "It's a surprising result," Jason T. Weir of the zoology...
