Earlham Institute (EI), with the University of East Anglia (UEA), have developed a new method to rapidly identify the sources of bee pollen to understand which flowers are important for bees.
A new study published in Science shows that farmers in northern India could increase their profits if they stop burning their rice straw and adopt no-till practices to grow wheat. Alternative farming practices could also cut farmers' greenhouse gas emissions from on-farm activities by as much as 78% and help lower air pollution in cities like New Delhi.
The first example of 'nest'-building in an African amphibian, the Goliath frog, has been described in a new article in the Journal of Natural History, and could explain why they have grown to be giant.
Some fossil plants that lived in wetlands had fungi living in their roots, and others don't. To understand why, scientists waded into modern wetlands and yanked up cattails to study the fungi living in their roots. They learned that cattail roots deeper underwater have fewer fungi living in them than in drier roots. That means that the fungi present in fossil plant roots can tell us about the environment those plants lived in.
Many university and college students across the US report lacking access to a reliable supply of nutritious food, a concept known as food insecurity, which can affect their ability to learn, according to research presented at the annual convention of the American Psychological Association.
When the Northern Spotted Owl was protected under the Endangered Species Act in 1990, the primary threat to the species was the loss of old-growth forest. However, new research shows that the Spotted Owl population in Washington's Mount Rainier National Park has declined sharply in the past two decades despite long-term preservation of habitat within the park. The culprit? The Barred Owl, a competing species that has moved into Spotted Owls' range from the east.
When ocean temperatures rise, corals are put at risk of a phenomenon known as bleaching, in which corals expel the algae living in their tissues and turn white. Bleached corals are at increased risk of disease and death. But, researchers reporting in the journal Current Biology on Aug. 8, 2019, now show that more severe marine heatwaves -- as occurred on Australia's Great Barrier Reef (GBR) in 2016 -- are even worse for corals.
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.
In the depths of the sea, certain shark species transform the ocean's blue light into a bright green color that only other sharks can see -- but how they biofluoresce has previously been unclear. In a study publishing Aug. 8, 2019 in the journal iScience, researchers have identified what's responsible for the sharks' bright green hue: a previously unknown family of small-molecule metabolites.
Marine heatwaves are a much bigger threat to coral reefs than previously thought, research revealing a previously unrecognized impact of climate change on coral reefs has shown.
