Green spaces don't ensure biodiversity in urban areas
Planting trees and creating green space in cities is good for attracting species, but it may not be enough to ensure biodiversity in built environments, a University of Iowa study has found.
Water research tackles growing grassland threat: Trees
Two Kansas State University biologists are studying streams to prevent tallgrass prairies from turning into shrublands and forests.
Researchers suggest reforestation around urban areas to reduce ozone levels
We mustn't waste water while taking action on climate change
Should we pick and choose our climate strategies based on how water-wise they are?
Genome could unlock eucalyptus potential for paper, fuel and fiber
From antiseptic oils to the construction of didgeridoos, the traditional Australian Aboriginal wind instrument, the eucalyptus tree serves myriad purposes, accounting for its status as one of the world's ...
Experiment confirms that insects play a key role in the pollination of cultivated plants
A lack of bees and other wild insects to pollinate crop plants can reduce harvest yields more drastically than a lack of fertilizer or a failure to provide the crops with sufficient water. When crops are ...
Smells like deceit: A record number of species use the same odor to exploit each other
The open-access journal Frontiers in Ecology and Evolution reports the first known case where four species, all at different levels in the food chain, use a single odor to communicate with and ruthlessly exploit each other. ...
Fungus may help stop invasive spread of tree-of-heaven
A naturally occurring fungus might help curb the spread of an invasive tree species that is threatening forests in most of the United States, according to researchers.
Bark beetles change Rocky Mountain stream flows, affect water quality
On Earth Week—and in fact, every week now—trees in mountains across the western United States are dying, thanks to an infestation of bark beetles that reproduce in the trees' inner bark.
Plants release chemical weapons and deploy insect armies in their defence
Animals have an easy life. They can run, hide, or bite back when predators are on the prowl. Plants cannot. Instead they have evolved to deploy a range of defence mechanisms including chemical warfare and ...
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 ...
Meloidogyne mali: A new invasive plant parasitic nematode in Europe
Following its recent synonymisation with Meloidogyne ulmi, a species known to parasitize elm trees in Europe, it has become clear that M. mali has been in the Netherlands for more than fifty years. ...
How plants evolved to weather the cold
A team of researchers studying plants has assembled the largest dated evolutionary tree, using it to show the order in which flowering plants evolved specific strategies, such as the seasonal shedding of ...
Cloning strong, high-quality forest trees
(Phys.org) —University of Georgia researchers are working to produce faster-growing sweetgum trees by growing embryogenic sweetgum cultures in bioreactors, computer-operated systems used for growing cells under controlled ...
