When Earth's species were rapidly diversifying nearly 500 million years ago, that evolution was driven by complex factors including global cooling, more oxygen in the atmosphere, and more nutrients in the oceans. But it took a combination of many global environmental and tectonic changes occurring simultaneously and combining like building blocks to produce rapid diversification into new species, according to a new study by Dr. Alycia Stigall, Professor of Geological Sciences at Ohio University.
Recent primate research has had a heavy focus on a few charismatic species and nationally protected parks and forests, leaving some lesser known primates and their habitats at risk, according researchers at The University of Texas at Austin and Santa Clara University.
A vast region of Africa affected by drought and changing land use emits as much carbon dioxide each year as 200 million cars, research suggests.
Recently, an international team led by Prof. TAN Liangcheng from the Institute of Earth Environment (IEE) of the Chinese Academy of Sciences developed a 2700-yr rainfall record of the northern central Indo-Pacific region.
New research led by Oxford University and Queen Mary University of London has resolved a pig paradox. Archaeological evidence has shown that pigs were domesticated in the Near East and as such, modern pigs should resemble Near Eastern wild boar. They do not. Instead, the genetic signatures of modern European domestic pigs resemble European wild boar.
A new study finds that if less than 1% of agricultural land was converted to solar panels, it would be sufficient to fulfill global electric energy demand.
Consecutive low snow years may become six times more common across the Western United States over the latter half of this century, leading to ecological and economic challenges such as expanded fire seasons and poor snow conditions at ski resorts, according to a new study.
The Devonian period (419 million to 359 million years ago), called the 'age of the fishes,' saw significant evolutionary progress in plants. Researchers reporting Aug. 8 in the journal Current Biology describe the largest example of a Devonian forest, made up of 250,000 square meters of fossilized lycopsid trees, which was recently discovered in China's Anhui province. Larger than Devonian forests in Norway and the US, the fossil forest is larger than Grand Central Station.
Groundwater maintains vital ecosystems and strongly influences water and energy budgets. Although at least 400 million people in sub-Saharan Africa depend on this valuable resource for their domestic water needs, the processes that sustain it and their sensitivity to climatic variability, are poorly understood. IIASA contributed to a study that looked into climate impacts on groundwater in light of changing climatic patterns in Africa.
Some volcanoes take their time--experiencing protracted, years-long periods of unrest before eventually erupting. This makes it difficult to forecast when they pose a danger to their surrounding areas, but Carnegie's Diana Roman and Penn State's Peter LaFemina are trying to change that.
