A Danish research team has found an incredible short-cut – a lake water sample the size of a shot-glass can contain evidence of an entire lake fauna.
It’s so effective in counting not only which creatures are present, but how many, that the researchers think that in future it may even be used to count fishing quotas.
Researchers at the Natural History Museum of Denmark found that rare and threatened animal species could be monitored simply by taking note of the DNA traces in fresh water environments.
‘In the water samples we found DNA from animals as different as an otter and a dragonfly,’ says Philip Francis Thomsen.
Designed by Stefano Boeri- architect, academic and former editor of design and architecture magazine Domus – his Bosco Verticaleis a towering 27-story structure, currently under construction in Milan, Italy.
Once complete, the tower will be home to the world’s first vertical forest.
In summer, oaks and amelanchiers will shade the windows and filter the city’s dust; in winter, sunlight will shrine through the bare branches.
(Reuters) – Heavy rains, deep snowfalls, monster floods and killing droughts are signs of a “new normal” of extreme U.S. weather events fueled by climate change, scientists and government planners said on Wednesday.
“It’s a new normal and I really do think that global weirding is the best way to describe what we’re seeing,” climate scientist Katharine Hayhoe of Texas Tech University told reporters.
“We are used to certain conditions and there’s a lot going on these days that is not what we’re used to, that is outside our current frame of reference,” Hayhoe said on a conference call with other experts, organized by the non-profit Union of Concerned Scientists.
