FREEPORT, Maine (AP) — Coastal Maine has a lot of seaweed , and a fair number of cows. A group of scientists and farmers think that pairing the two could help unlock a way to cope with a warming world. The researchers — from a marine science lab, an agriculture center and universities in northern...

FILE - In this Oct. 5, 1994, file photo, two bison graze in a meadow in Yellowstone National Park, Wyo. New research shows when bison heavily graze an area, the grass greens up earlier and faster and stays green for a much longer period of time. Researchers with the park and area universities say the bison are able to graze in one area for two to three months rather than having to move to higher elevations to follow new plant growth. Sensors on NASA satellites are able to observe the grassland dynamics. (AP Photo/Dave Zalubowski, File)

MISSOULA, Mont. (AP) — A study of grazing in Yellowstone National Park found that bison essentially mow and fertilize their own food. This allows them to graze in one area for two to three months during the spring and summer while other hoofed mammals must keep migrating to higher elevations to...

An unmodified, open-pollinated American chestnut bur grows on a tree at the State University of New York's College of Environmental Science & Forestry Lafayette Road Experiment Station in Syracuse, N.Y., Monday, Sept. 30, 2019. The ESF American Chestnut Research & Restoration Project researchers have been able to add a gene to American chestnuts that give the trees resistance to a blight that decimated the trees in the 20th century.

SYRACUSE, N.Y. (AP) — Chestnuts harvested from high branches on a chilly fall morning look typical: they're marble sized, russet colored and nestled in prickly burs. But many are like no other nuts in nature. In a feat of genetic engineering, about half the chestnuts collected at this college...

In this undated handout photo provided by International Union for Conservation of Nature, a critically endangered Sorbus rhodanthera is seen in Czech Republic. An international conservation group is warning that more than half of the trees in Europe that exist nowhere else in the world are threatened with extinction. The International Union for the Conservation of Nature says in their latest assessment of Europe’s biodiversity that 58% of the 454 trees species native to the continent are threatened, and 15% are “critically endangered” - one step away from extinction.

California citrus growers, packers and researchers gather for the opening of a new secure lab dedicated to the search for a cure for a deadly citrus-killing disease in Riverside, Calif., Thursday, Sept. 26, 2019. Growers hope the lab will speed up the search for a cure to the disease, which is spread by a tiny insect and has ravaged groves in Florida and abroad. The lab will be run through a partnership with University of California, Riverside. (AP Photo/Amy Taxin)
