Indiana University paleobotanist David Dilcher and colleagues in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on Earth.
A group of Woods Hole Oceanographic Institution (WHOI) researchers and engineers have developed and tested an innovative new system for sampling small planktonic larvae in coastal ocean waters and understanding their distribution.
Kalmar/Halle(Saale). Why some species of plants and animals vary more in number than others is a central issue in ecology. Now researchers at Linnaeus University in Sweden and from the Helmholtz Centre for Environmental Research (UFZ) have found an important finding to answer this question: Individual differences have a positive and stabilizing effect on the number of moths.
Eastern North America is home to a small population of Golden Eagles (Aquila chrysaetos), but despite their potential vulnerability to habitat loss and other threats, little information has been available on the patterns of their annual migration.
When it comes to reproduction, not every individual equally pulls his or her weight. Dana Herman and Mark Colwell of Humboldt State University spent 13 years tracking the successes and failures of almost 200 individual Snowy Plovers (Charadrius nivosus) nesting at a variety of sites in Humboldt County, California, to identify the factors that could be influencing reproductive success for birds in this threatened population.
The wild boar population in Europe has been constantly growing since the 1980s. This is more and more becoming a problem for agriculture when animals raid the fields, looking for feed. “It is not so easy to determine the number of wild boars in Europe,” says wildlife biologist and first author of the study, Sebastian Vetter. “Therefore we analysed data on hunting bags and road accidents involving wild boar. Doing this we were able to depict the growth of the wild boar population.”
In the spring of 2010, the Deepwater Horizon drilling platform exploded, initiating an uncontrolled deep-water oil and gas blowout from the Macondo wellhead. The uncontrolled hydrocarbon discharge continued for 85 days and the environmental impacts were substantial.
Climate change, environmental pollution or land use changes - there are numerous influences threatening biodiversity in forests around the globe. The resulting decrease in biodiversity is a matter of common knowledge today - amongst scientists as well as amongst the general public.
A collaborative study led by international conservation charity the Zoological Society of London (ZSL) has found that harbour porpoises (Phocoena phocoena) are struggling to successfully reproduce as a result of chemical pollutants found in European waters.
The Nature Conservancy has completed its first phase of installation of SheerWind's INVELOX funnel-based wind power technology. Because Palmyra is home to a national wildlife refuge and more than a million nesting seabirds, conventional wind turbines were not an option due to the risk of bird strikes. What's more, the low wind speeds on the island would provide little to no energy production with traditional turbines.
