Amazon's canopy chemistry is a patchwork quilt
In many ways, plants act as chemical factories, using energy from sunlight to produce carbon-based energy and taking nutrients from the soil in order to synthesize a wide variety of products. Carnegie scientists ...
Excessive deer populations hurt native plant biodiversity
(Phys.org) —Too much garlic mustard in your neighborhood forest? Actually, the problem may be too many deer.
Shade will be a precious resource to lizards in a warming world
Climate change may even test lizards' famous ability to tolerate and escape the heat—making habitat protection increasingly vital—according to a new study by UBC and international biodiversity experts.
Farm salmon pose clear reproductive threat to wild gene pools
Farmed salmon show full reproductive potential to invade wild gene pools and should be sterilised - according to new research from the University of East Anglia (UEA).
Study finds herbivores can offset loss of plant biodiversity in grassland
Two wrongs may not make a right. But when it comes to grassland plant species diversity, it just might. Two impacts often controlled by humans—being fertilized and being eaten—can combine to the benefit ...
Deer proliferation disrupts a forest's natural growth
By literally looking below the surface and digging up the dirt, Cornell researchers have discovered that a burgeoning deer population forever alters the progression of a forest's natural future by creating environmental havoc ...
Warming temperatures are pushing two chickadee species—and their hybrids—northward
The zone of overlap between two popular, closely related backyard birds is moving northward at a rate that matches warming winter temperatures, according to a study by researchers from the Cornell Lab of ...
Livestock can produce food that is better for the people and the planet
With one in seven humans undernourished, and with the challenges of population growth and climate change, the need for efficient food production has never been greater. Eight strategies to cut the environmental and economic ...
Female coyotes can have mixed wolf-coyote pups
Scientists have successfully produced hybrid pups between a male western gray wolf and a female western coyote in captivity.
Sea turtles 'lost years' mystery starts to unravel
Small satellite-tracking devices attached to sea turtles swimming off Florida's coast have delivered first-of-its-kind data that could help unlock they mystery of what endangered turtles do during the "lost ...
Large mammals were the architects in prehistoric ecosystems
Elephants, rhinoceroses and aurochs once roamed around freely in the forests of Europe, while hippopotamuses lived in rivers such as the Thames and the Rhine. New research shows how we can use knowledge about ...
Ninety-five per cent of world's fish hide in mesopelagic zone
An international team of marine biologists has found mesopelagic fish in the earth's oceans constitute 10 to 30 times more biomass than previously thought.
Animal forensics, DNA used to estimate river otter population
The restoration of Pennsylvania's river-otter population has been, by all accounts, a great success, and a study being conducted by researchers in Penn State's College of Agricultural Sciences will soon quantify ...
Climate change causes high, but predictable, extinction risks
Judging the effects of climate change on extinction may be easier than previously thought, according to a paper published today in the journal Nature Climate Change.
