Human activities, such as shipping, are having a noticeable impact on marine species and their native habitats. New research says that human forms of transport can disrupt natural genetic patterns that have been shaped over long periods of time. This has unknown consequences for both native and invasive species.
Rockcress of the Arabidopsis halleri species is known to possess the capability of settling on hostile, heavy metal-contaminated soil. It stores extraordinary high concentrations of certain toxic heavy metals in its leaves: a rare property. Researchers have analyzed approx. 2,000 specimens of this species from 165 locations throughout Europe. In this process, they identified overwhelming diversity that has arisen among plants of the same species over the course of evolution. Their findings help explore plants’ enormous potential for future technologies; in this case, they aid the detoxification of soil and the extraction of metals that are of economic interest.
Forests provide multiple social and environmental benefits and play a key role in bioeconomy particularly in the Nordic countries. For example, the Finnish bioeconomy strategy aims to considerably increase the use of forest-based biomasses and forest harvesting by 2025. However, new research shows that there are strong conflicts between intensive timber harvesting and the provision of other benefits or the maintenance of biodiversity.
Wind patterns in the lowest 500 meters of the atmosphere near supercell thunderstorms can help predict whether that storm will generate a tornado, report investigators.
