The environmental impact of hydropower generation in the Amazon may be greater than predicted, according to new University of Stirling research.
For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy's Oak Ridge National Laboratory. The investigators discovered that treating a complex oxide crystal with either heat or chemicals caused different atoms to segregate on the surface, i.e., surface reconstruction. Those differences created catalysts with dissimilar behaviors, which encouraged different reaction pathways and ultimately yielded distinct products.
Interactions between species play a key role in shaping biodiversity. A team of researchers including members of UZH has now shown that the coevolution of species that are embedded in complex networks of interactions is not only influenced directly by their partners but also indirectly by other species. This slows down the ability of complex communities to adapt to environmental change. Rapid climate changes are therefore likely to increase species' risk of becoming extinct.
Since 1989, in 63 nature reserves in Germany the total biomass of flying insects has decreased by more than 75 percent. This decrease has long been suspected but has turned out to be more severe than previously thought. Ecologists from Radboud University together with German and English colleagues published these findings in the scientific journal PLOS ONE on Oct. 18.
The world's tropical forests are in 'a critical state' in which the extinction of rare tree species could be a tipping point, according to an international team of scientists who have developed an analytical method to map their biodiversity.
New study finds 'messy' microscopic structures on petals of some flowers manipulate light to produce a blue colour effect that is easily seen by bee pollinators. Researchers say these petal grooves evolved independently multiple times across flowering plants, but produce the same result: a floral halo of blue-to-ultraviolet light.
With warm, dry summers comes a deadly caveat for the western United States: wildfires. Scientists say the hot, dry climates found west of the Mississippi, along with decades of fire suppression efforts, are creating a devastating and destructive combination -- leading to fires like the ones currently burning in California. Now, new research from The University of New Mexico is giving forest and fire management teams across the country the upper hand in reducing the severity of these events.
University of Guelph researchers have published what is believed to be the first scientific paper in North America on improving medicinal cannabis plant production, helping move the industry into the realm of high-tech laboratories and evidence-based practices. This paper is the first of a series of studies University of Guelph researchers have conducted investigating ideal horticultural practices for indoor cannabis production in response to industry demand.
Conservationists can be 'cautiously optimistic' about the prospect of sustainable subsistence hunting by Amazonian communities -- according to new research from the University of East Anglia (UK). The research team spent over a year working with 60 Amazonian communities and hiked for miles through trackless forests to deploy nearly 400 motion-activated camera traps -- in a bid to understand which species are depleted by hunting and where.
The harlequin ladybird, officially known as Harmonia axyridis, was widely introduced across continental Europe to limit the population of pest insects.
