Green Blog: Pace of Ocean Acidification Has No Parallel in 300 Million Years, Paper Finds 2012-03-02T23:11:49Z “Our ecological niche is that we help teachers deal with the political and social problem involved with the teaching of evolution,” Dr. Scott said. Green Blog: Helping Teachers Stand Up for Science 2012-01-17T17:21:06Z The skulls and physiques of these predators were remarkably similar, and the creatures occupied comparable ecological niches, Meachen-Samuels says. Sturdy Arms Were Secret to the Saber-Tooth's Success 2012-01-06T20:13:37Z Obviously, the diversity of ecological niches in the rainforest is sufficient to support a variety of related species. Amphibians and Reptiles of the Rainforests of Southern El Peten, Guatemala 2011-12-25T03:00:10.957Z Possibly this is because the habitat, or even the ecological niche, occupied in geological time by these mice was restricted, geographically and in kind. Speciation and Evolution of the Pygmy Mice, Genus Baiomys 2011-12-15T03:00:11.933Z Clearly there are ecological niches, or ways of life that are occupied by the first comer and difficult to invade. Scientist at Work Blog: Magical Days on Panamoti Island 2011-10-11T16:03:18Z All of these critters occupy distinct ecological niches, and one of the goals of this two-year study is to understand how the different trophic levels interact and how the methane moves through the system. Scientist at Work Blog: Return to Hydrate Ridge 2011-09-02T00:51:45Z Roughly speaking, these animals filled the ecological niches now occupied by toothed cetaceans such as dolphins and killer whales. Prehistoric reptiles: A loving mother 2011-08-10T18:18:00Z The enriched genera indicate that enterotypes use different routes to generate energy from fermentable substrates available in the colon, reminiscent of a potential specialization in ecological niches or guilds. Enterotypes of the human gut microbiome 2011-05-11T17:21:02.573Z The resemblance of B. rexroadi to B. taylori may result from each having occupied the same ecological niche in different periods. Speciation and Evolution of the Pygmy Mice, Genus Baiomys 2011-12-15T03:00:11.933Z But the latest paper deals with the ecological niche it occupied in Australia. Extinct 'wolf' hunted like a cat 2011-05-04T07:19:55Z The other was an ecological niche for the virus in a human population unprepared to fight back. Edwin Kilbourne, Flu Vaccine Expert, Dies at 90 2011-02-25T05:05:24Z It would mean plesiosaurs not only occupied a similar ecological niche to whales, but behaved like them, too. Prehistoric reptiles: A loving mother 2011-08-10T18:18:00Z Here was evolution in action, organisms over time responding to changing fortunes through natural experimentation in new body forms and different ecological niches. Fossil Trove Shows Diverse Creatures of Cambrian Did Not Disappear 2010-05-17T21:58:00Z The team looked at orcas inhabiting seven ecological niches around the world. Cracking Orca?s DNA Code 2010-04-26T22:42:00Z Knowing this, the researchers suspected a difference in diet and ecological niche between the two groups. 2010-01-05T14:40:00Z Because the genera Eutamias and Tamias occupy similar ecological niches, the structural similarities that permit these animals to be called chipmunks, show convergence, and thus can be assumed to be adaptive.
