Researchers have known since at least 2008 that wildfires can create chromium-6, but a new study, published in the journal Environmental Science and Technology in November, is the first to report details such as how long it might persist in groundwater.
The industrious buzz of bees tackling the dregs of cherry blossom was lawnmower-loud, accompanied by back off peeps from blackbirds nesting in the ivy.
To make hummingbird feed that is as close as possible to the nectar that the birds consume naturally, only use refined white sugar and water. Do not add anything else, especially not red dye, which can be harmful to hummingbirds.
These beautiful cherry trees are more than a visual delight - they represent a bond between nations, a gift to our local communities, and a lasting legacy. We know after our long winters, people rejoice seeing colour and blossom, and this sea of pink will be an awe-inspiring hit of horticultural wonder.
A study by researchers at the University of California Berkeley has found that ethanol is surprisingly common in floral nectar, the sugary fuel that keeps pollinators alive. Yeast feeding on those sugars produces trace amounts of alcohol, and in this study, it showed up in 26 of the 29 plant species sampled.
The fierce Maniot people were well described by Patrick Leigh Fermor in his book Mani (1958), but the region has been more recently celebrated in Charles Foster's brilliant The Edges of the World, published in January. In history the Mani was known variously for the relentless and sometimes centuries-long vendettas between its local clans, as a fertile recruiting ground for Mediterranean piracy and as an early outpost for Greek liberation from Ottoman rule.
'Our results show that the next 20 years are critical,' lead author Dr Rob Cooke told the Daily Mail. 'By around 2050, we reach a point where the choices we make on emissions and land use will largely determine whether Britain moves towards a much more degraded or a much more nature‑positive future.'
Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.
First came the heavy winter rains that soaked the soil. Then, the sunny weather not too hot, but just warm enough to fuel the growth. A few more winter rainfalls and Southern California could be ripe for an epic wildflower season in the coming weeks and months. And when they bloom the vibrant colors popping from rolling hills as far as the eye can see thousands of people are bound to seek out their beauty, if past years are any indication.
For Staller, foraging is a "precious" and "simple" activity that one can do to connect with nature. They can experience a sense of mindfulness from gathering together, looking for food and then cooking the bounty, she said. "We are returning to the most basic part of being a human, which is eating food and celebrating it," Staller said. "It's a lost artform."
Conservationists have now persuaded landowners to cut hedges in a more gentle rotation, with sections left uncut for up to three years, to enable more eggs to survive over winter. The caterpillars emerge with the foliage in spring and hatch into adult butterflies in July. The brown hairstreak is difficult to spot as a butterfly but every winter volunteers assess its populations by counting its minuscule cream-coloured eggs, which with careful searching are visible on the bare branches of blackthorn.
The work suggested that resistance arises from a relatively large number of sites, each with relatively minor effects. For example, the sites in the genome identified by quantitative trait analysis typically boosted resistance by about 10 points on the researchers' 100-point scale. In the genome-wide analysis, 17 individual genetic differences were associated with about a quarter of the heritable resistance traits.
It was previously thought that tropical regions where temperatures fluctuate less over the course of the year would not be so affected by the climate crisis in terms of the timing of flowering. This hypothesis has been proved wrong, said the lead researcher Skylar Graves from the University of Colorado Boulder, who added that nowhere on Earth is unaffected by climate change.
Originally due to be published in the autumn, the review appears to have had some sections removed. An earlier version is reported to have included warnings about the risks of eco-terrorism and the growing likelihood of war between China, India and Pakistan due to competition over a shrinking water supply from the Himalayas.
Wildlife populations are in decline. Recreation sites are crowded and often underfunded. Wildfires are larger, more destructive and harder to control. Climate change is reshaping natural systems, from ocean fisheries to mountain snowpacks, faster than institutions can respond. At the same time, communities are being asked to host new energy projects, transmission lines and mineral development - often without clear processes, adequate resources or trust that decisions are being made in the public interest.
Waterways across Contra Costa County are increasingly threatened by invasive plant species that engulf canals and drains, decreasing biodiversity and reducing safe habitats for wildlife. In an effort to address and restore the environment, the Contra Costa County Flood Control and Water Conservation District is working to reverse that trend. The district hosted its recent 12th annual Giving Natives a Chance event at the Clayton Valley Drain near Concord's Hillcrest Community Park, inviting volunteers from across the county to plant native species around waterways and drains.
