The paleoclimatic record shows it has happened before – and now two well-read researchers illustrate it is already happening again: species across life’s kingdoms are decreasing in size, due to warming, droughts and acidification. It’s a sign ecology is feeling … Continue reading
Since the 1860′s nitrogen additions to the terrestrial biosphere have more than doubled, due to human activities. Since nitrogen is a key nutrient needed for plant growth and therefore used as a fertiliser, the additions have made a drastic increase … Continue reading
Just like human beings plants too have a biological clock, which prepares them to make optimal use of both day and night – and which helps them to nicely tune their annual growth cycle within the appropriate seasons. It is … Continue reading
As the world warms, access to fresh water will become less and less obvious which is bad in itself, but as it turns out now, water shortages could contribute to even more warming through a positive feedback loop.
It started in the 1980s: a sudden levelling of methane release into the atmosphere. It was a mystery as to why it happened. Now scientists have found the answer to the mystery, or in fact they have found two different … Continue reading
Breeding crops with deeper (and larger) root systems could help to lower atmospheric CO2 levels, while also making the crops better drought-resistant, Douglas Kell, a Professor of Bioanalytical Science at the University of Manchester says.
Researchers of Oxford University and Earthwatch UK find farmland rich in pollen distracts pollinating insects from nearby nature reserves.
Sometimes, when confronted with the promises of technology, we are tempted to dream away to a planet where we could cheer at yet another billion extra people, where we could set our livestock free to let wolves and big cats … Continue reading
‘Some 35 percent’ of the foods we eat [and two-thirds to three-quarters of the crop foods] are derived from flowering plants and trees that depend on pollination by insects. This often-cited percentage is used to stress the importance of bees … Continue reading
Scientists from UC San Fransisco have finished a ten month bee survey and last week published their findings in PLoS ONE. It turns out American bee hyves are swarmed with viruses and other pathogens.
