Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern United States and southern Canada, says a new study.
Forests in the south-central United States are some of the country’s most productive and diverse. They also sit in a warming “hole”—an area where the progressive rise in temperature affecting most of the continent hasn’t yet taken hold. A team from Columbia University’s Lamont-Doherty Earth Observatory is studying how these forests might shift—or even disappear—when climate change does catch up with them, as expected.
One foggy spring morning just after a hard rain, Park Williams was tromping through the woods deep in Arkansas’ Ozark Mountains. Toiling down a steep slope, he supposedly was keeping a simultaneous eye out for rattlesnakes, copperheads, poison ivy and big old trees. Williams seemed mostly focused on the trees, though; attention to the other stuff was just slowing him down. Williams studies how forests react to changes in climate, and the Ozarks’ deeply dissected hills and hollers—what some might refer to as typical hillbilly country—are a kind of ground zero for this.
Seeing the Amazon’s Future Through the Fog
Scientists have developed a new approach to modeling the water and carbon cycles in the Amazon that could lead to better climate forecasts and improved water resource management.
Forests are a vitally important habitat for much of the world’s terrestrial biodiversity. During this class you will learn key issues in forest ecology and management through an all-day field trip to Black Rock Forest, and study how pathogens and other invasive species affect forest structure and function.
As you travel through our region, you may notice stands of trees with branch tips covered in dead leaves. The damage is not from the hot and humid weather, but rather the aftermath of the cicadas.
The SEE-U Puerto Rico course provides students with a total immersion experience into the ecology and dynamics of a fragile and threatened environmental system.
In the previous post, I outlined the argument lighting up parts of the New Jersey legislature and the human elements of its ecological communities. Briefly, one reason some people are using to promote logging on public lands is the perception that old trees and forests are dying of old age. While there are other arguments… read more
“There is unrest in the forest, there is trouble with the trees“…I will mostly spare you one of the more ecologically correct, forest ecology rock tunes (the next two lines, however, “For the maples want more sunlight, and the oaks ignore their pleas,” written in 1978, seem incredibly prescient given that one of the first… read more
