Researchers excavating ancient salmon chum bones from the Upward Sun River site in Alaska have found that Ice Age humans had a broader diet than previously surmised and used specialized tools to fish.
Tropical mountain regions in Ecuador face significant impacts from climate change. Over the past two hundred years, vegetation on the Chimborazo volcano in Ecuador has migrated over 500 meters upslope.
Migrating birds need to take the occasional break during their long migrations. Researchers recently examined how they choose where to rest. Surprisingly, it isn't at a food court on the Delaware-Maryland border.
Climate change and habitat loss are two major threats posed to animal species worldwide. And especially with global temperatures rising in recent decades (2014 was the hottest year yet), scientists are now concerned more than ever with the survival of Earth's animals. However, recent research suggests that they are more flexible than you think.
Well, not quite. But new remarkable research has shown that in the longest ever tiger tracking study, these predators boast migration patterns more similar to birds, turtles and some marine mammals than other fishes.
The Bronze Age was a significant era in Earth's early history, but how did it change Europe? New DNA analyses from the bones of early Europeans have attempted to answer just that question, showing that the demographic structure of present-day Europe and Asia is the result of widespread population migrations, and subsequent cultural changes that occurred during the Bronze Age.
We all know that it's hard to keep up appearances when you're constantly on the go. That's why the fashion police will probably give some female warblers a free pass, even after researchers found that they boast drabber feather when their migration routes are particularly long.
Scientists are confident that all modern human populations can trace their ancestry back to Africa, yet the road they traveled along has remained unclear. But now, new research indicates that Egypt may be the key to the ancient human migration out of Africa.
Massive bird invasions taking place across the United States and Canada, a phenomenon that has long puzzled scientists and birdwatchers alike, is reportedly linked to climate shifts, new research indicates.
Scientists have long debated about how the first inhabitants arrived to North America, and now one popular "ice bridge" theory has definitively been disproved, according to new research.
Experts have some new plans for the International Space Station (ISS), and they have absolutely nothing to do with space, exploration, or even astronauts. A new investigation will be using the uniquely high vantage point of the orbital space station to help track animals in trouble - the results of which could improve conservation strategies around the world.
It's a new record! US and Russian scientists recently documented the longest migration of a mammal ever recorded - a whopping 14,000 miles by a supposedly endangered gray whale. Now experts are wondering how endangered the species actually is.
The blackpoll warbler, a songbird that weighs no more than a ball-point pen, is a rather unassuming traveler. Flitting around boreal forests in Canada and the Northern US, these birds spend their winters in South America. Now, researchers have learned that they make that entire 1,500-mile trip without ever taking a break.
Thousands of snow geese mysteriously dropped dead in Idaho during their annual migration, wildlife managers said Monday, and experts are trying to figure out why.
