Yellow-bellied marmots are a North American species of ground squirrel.
New research on marmots in the US reveals how the topsy-turvy seasons are causing havoc among wildlife.
Collecting data on invasive plants, Santa Monica Mountains National Recreation Area, California.
The COVID-19 pandemic is interrupting scientific field work across North America, leaving blank spots in important data sets and making it harder to track ecological change.
Yellow trout lily flowers nearly a week earlier now than in previous decades in the Appalachian Mountains.
Climate change has advanced the arrival of spring by as much as several weeks in some parts of the US. This can mean major crop losses and disconnects between species that need each other to thrive.
A mast year can be a squirrel’s dream come true.
Masting is what biologists call the pattern of trees for miles around synchronizing to all produce lots of seeds – or very few. Why and how do they get on schedule?
The silver-studded blue butterfly is among that species that may be flexible enough to thrive.
We looked at 130 species to see which will be the winners and losers from global warming
What can your vacation pix tell scientists?
To untangle the relationship between climate change, fall foliage and national park visitors, researchers are asking tourists to check their old photo albums for snapshots that could hold valuable data.
The longest phenological record derive from the cherry blossoms in Japan.
Monitoring the timing of recurring biological events is key to understanding the effects of climate change.
South Africa's annual sardine run is occurring increasingly late, and there have been instances where it doesn't happen at all. Here's why.
A grizzly bear eats ripe buffaloberry fruit in the Bow Valley of Alberta. Shifts in the timing of buffaloberry development in the Rocky Mountains will change the behaviour of grizzly bears, and could threaten reproductive rates in this vulnerable population.

As warming temperatures shift the availability of key food sources, Alberta's grizzly bears will be forced to adjust.
Record heat in February 2019 caused shock and delight in equal measure. Behind the balmy weather lie challenges for British wildlife.
Whistling tree frogs, Litoria verreauxii, are one of the species monitored around Canberra for their response to climate change.

Climate change can seem far removed from our everyday lives, which is why a citizen science program measuring how frogs are dealing with a warming world is so important.
A brown bear snags a sockeye salmon in Alaska. In warm years, red elderberries ripen early and Kodiak bears leave streams full of salmon to eat them.
Climate change is making berries ripen early in Kodiak, Alaska, luring bears away from eating salmon. This shift may not hurt the bears, but could have far-reaching impacts on surrounding forests.
Denali National Park, Alaska.
Snowshoe hares in warmer zones have thinner fur, and some are not turning white in winter. As climate change warms the Northeast, will this species adapt?
Mountain Pygmy Possum numbers are declining due to environmental changes, including earlier snow melt.
Every Spring, the blanket of Australian alpine snow starts to melt, and the Mountain Pygmy Possum wakes up from its seven-month-long hibernation. Naturally after so long under the snow, its first thought…
