Potential for enhanced sequestration of carbon in soils supports evaluations
...tributes to ongoing global warming that is causing ecological
disruption and threatens human populations. The researchers note that a variety of land-use practices have apparently favorable potential for increasing carbon dioxide uptake, including intensifying cropping, adding organic material to soil, conserva...
Climate change plus human pressure caused large mammal extinctions in late Pleistocene
...ide. This new analysis of archeological, climatic, ecological
and simulation studies shows that these extinctions happened around the world. Of more than 150 genera of megafauna - that is, animals weighing more than 44 kilograms (97 pounds) - living on Earth 50,000 years ago, at least 97 were extinct by 10,000 ...
Atacama rover helps NASA learn to search for life on Mars
...es scientist Chris McKay is conducting a long-term ecological
study of the Atacama as a Mars analog environment. Scientists using EventScope, a remote experience browser developed by researchers at Carnegie Mellon's Studio for Creative Inquiry, will guide Zoe. EventScope enables scientists to experience...
Pollutant causes delayed flowering in plants
..., I would bet that these findings have large-scale ecological
implications regarding the effects of air pollution on flowering. It is entirely possible that global pollution by oxides of nitrogen could delay plant flowering worldwide," Pei said. Pei and his colleagues began their studies by exposing the seedlin...

...alactose, suggesting that the yeast experienced an ecological
shift that somehow removed galactose from the organism's menu, thereby making the galactose-processing genes obsolete. The relic genes, according to Hittinger, are "full of holes," where numerous DNA bases - the building blocks of all genes - have be...

features of this land for the people of Chile. The transfer represents one of the most significant gifts of private land worldwide, due to the size of the land (approximately equal in size to the state of Rhode Island), the ecosystems it contains and...

environment with large areas of old-growth forests in order to survive, and most things that disrupt the natural environment will be detrimental to them." "In this manner, studying caribou is especially important because caribou are what we call an '...
Essential smell gene may provide key to new insect repellents
