How climate change is driving monkeys and lemurs from trees to the ground

By Scott Dance Photo: Gunter Lenz, Shutterstock

The stresses of warming temperatures and forest losses are driving dozens of species of monkeys and lemurs that normally shelter and feed high in the tree canopy to spend more time foraging on the forest floor, according to a study published Monday.

Four Birds from Golden Gate and Yosemite Star in New Study of Migratory Species’ Responses to Climate Change

By Jessica Weinberg McClosky Photo: Garth Harwood

Scientists have abundant data on bird population trends and on climate change impacts to habitats around the world. For birds that stay in one place year round, linking the two to study bird population responses to climate change is relatively straightforward. But migratory birds….migrate. Every year they rely on multiple habitats in different parts of the world at different times. As a result, all of that existing data isn’t enough to tease apart how climate impacts birds at different stages of their annual journeys—or to inform more effective conservation strategies…

How urban sprawl and climate change affect animal migration

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.

Protecting endangered species by relocating them?

By Jeniffer Solis

Wildlife officials are proposing an ambitious policy to protect plants and animals from climate change: by moving threatened species to greener pastures. In June, the U.S. Fish and Wildlife Service proposed a change to the Endangered Species Act that would allow federally protected plants and animals to be introduced in areas where they’ve never lived before.

Lazy Bears and Confused Birds: What a Warming Planet Means for Wildlife

By David J. Craig Photo: Ted Kerasote , Science Photo Library

The Alaskan tundra, a vast, windswept, and treeless region at the edge of the Arctic Circle, is a place of stunning natural beauty. In winter, the area is blanketed by darkness, and polar bears, wolves, foxes, and lynx rule the snow-covered landscape. In summer, when the sun floats above the horizon for nearly twenty-four hours a day, temperatures routinely hit the mid-sixties, and the tundra springs to life. Patches of grass, wildflowers, moss, and shrubs emerge from beneath the melting snow; thundering herds of caribou, moose, and musk ox travel north to feast on the lush vegetation; and millions of birds from all over the world, drawn by a bounty of insects, worms, and berries, swoop in to mate and raise families.

‘Wholly Unexpected’: These Polar Bears Can Survive With Less Sea Ice

By Henry Fountain Photo: Kristin Laidre , University of Washington

The discovery suggests a way that a small number of bears might survive as warming continues and more of the sea ice that they normally depend on disappears. But the researchers and other polar experts cautioned that grave risks to the overall polar bear population in the Arctic remain and will only be lessened by cutting greenhouse gas emissions to curb global warming.

Ms. Fleshman, a nurse at the time, had earlier that evening hosted a cookout at her home in Greenwood, Del., a town of about 1,000 people 25 miles south of Dover. She drank a couple of beers. She ate a cheeseburger.

Ungulate Migration In A Changing Climate

By Katherine C. Malpeli

Migratory behavior among ungulates in the Western United States occurs in response to changing forage quality and quantity, weather patterns, and predation risk. As snow melts and vegetation green-up begins in late spring and early summer, many migratory ungulates leave their winter range and move to higher elevation summer ranges to access high-quality forage and areas with vegetative cover for protection during fawning. Ungulates remain on these ranges until the fall when increasing snowfall and decreasing temperatures trigger them to migrate back to their lower elevation winter ranges. While researchers have begun to assess the effects of physical barriers such as roads and energy infrastructure on migration, less attention has been paid to understanding how changing climate conditions might affect ungulate movements and range habitats. Does earlier spring green-up make ungulates leave their winter ranges sooner? Do persistent drought conditions reduce the carrying capacity of seasonal range habitats or lead to shifts in migration pathways? These and other questions remain largely unanswered but could have cascading effects on ungulate population dynamics and migratory behavior.

Birds Are Laying Eggs Earlier Likely Due to Climate Change

By Mary Jo DiLonardo Photo: Getty Images

It’s an annual harbinger of spring: Birds singing, building nests, and laying eggs. But the timetable has been gradually changing. A new study finds that many bird species are building their nests and laying eggs nearly a month earlier than they did a century ago.1
