Those young squirrels now scampering around your neighbourhood were born in this year’s earliest litters and are more likely to survive than squirrels born later and still curled up in their nests, according to a new University of Guelph study.

That’s because when it comes to survival in the squirrel world, the first out of the nest is best, said David Fisher, a post-doctoral researcher and lead author of the study conducted on squirrels in Yukon.

Forest birds on the island of Hawaii are responding positively to being restored in one of the largest, ongoing reforestation projects at Hakalau Forest National Wildlife Refuge, according to a new study released July 10 in the journal Restoration Ecology.

Serving as pollinators and seed dispersers, birds have an important role in ecosystem function and their presence in restoration areas can be a measure of success for conservation efforts.

No bells tolled when the last Catarina pupfish on Earth died. Newspapers didn’t carry the story when the Christmas Island pipistrelle vanished forever.

When Jeremy Goldbogen, an assistant professor of biology at Stanford University, affixed recording devices to humpback whales, it was with the hope of learning more about how the animals move in their natural environment – deep underwater and far from human’s ability to observe.

Iron-rich meltwater from Greenland’s glaciers are helping fuel a summer bloom of phytoplankton.

Right now, a prairie dog in Colorado is busy increasing soil carbon retention, increasing water infiltration, and clipping vegetation that will help maintain local grasslands and provide nutritious forage for large herbivores like cattle and bison. And, somewhere in Mexico, a pollinating bat is ensuring agave plants make good tequila.

University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small ‘weedy’ species dominating marine environments. 

Hot new imagery from temperature-sensing cameras suggests that bats who warm up from hibernation together throughout the winter may be better at surviving white nose syndrome, a disease caused by a cold-loving fungus ravaging insect-eating bat populations in the United States and Canada. The study by researchers with Massey University in New Zealand and the USGS was published in Methods in Ecology and Evolution.  

There are so many Antarctic krill in the Southern Ocean that the combined mass of these tiny aquatic organisms is more than that of the world’s 7.5 billion human inhabitants.

Scientists have long known about this important zooplankton species, but they haven’t been certain why particular regions or “hotspots” in the Southern Ocean are so productive.

Four hundred million lines of text: that’s how much data is in a single gene-sequencing file when Scott Pavey’s team receives it. If you wanted to scan it manually, and generously assume it would take one second per line to look at, it would take you 12 and a half years of reading around the clock to get through it all.
