Increasing tempertaures and humidity could lessen the productivity of grasslands in California.
Using fossilized teeth, researchers found that humans adapted a grass-based diet 400,000 years earlier than previously thought. This sheds light on how habitat change shaped human evolution.
This is the first summer for the 30 bison restored to prairie grasslands maintained by the Illinois chapter of the Nature Conservancy. They're much better than your lawnmower, regardless of its brand.
Parasitic "vampire" plants may get a bad rep from their name, but new research shows that they aren't so bad, after all, and that they could actually benefit the abundance and diversity of vegetation and animal life around them.
Invasive grasses and weeds have been slowly moving into California's pastures, making things harder for the local grasses that livestock have relied on for generations. Now, researchers are saying that if farmers let the grasslands rest, they can get healthy enough to resist invasion.
It turns out that creepy crawlers such as earthworms and beetles are crucial to the structure of grasslands, proving that things underground are just as important as those aboveground.
Trees are currently threatening growing grasslands, turning tallgrass prairies into shrublands and forests, and a pair of researchers is concerned that if nothing is done to stop or slow down this process, an important part of the ecosystem may soon be lost.
