Rivers are warming and losing oxygen faster than oceans, according to a Penn State-led study published in the journal Nature Climate Change. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.

In "Homo Ecophagus," Dr. Warren Hern gives human activity a deadly diagnosis

Owls are masterpieces of adaption, having honed their expertise as night predators over millions of years. Two new books delve into the world of these birds and the battle to protect certain species.

It’s named for frontier naturalist Gabriel Marnoch, who led a life of crime while discovering new species.

Victorian grassland earless dragon was once common west of Melbourne but numbers declined due to habitat loss and predators such as feral cats

Before the colonists came, we managed the land with careful use of cool burns. To stop giant bushfires, we have to learn again how to care for country.

Researchers tracked 2,300 wild mammals during the strict 2020 lockdowns and found they moved 73% further than in the previous year.

Between April and May, the birch pollen season is in full swing. Eyes water, throats sting, noses run: doctors call these immune reactions "allergic rhinitis."

The dodo's genome has been sequenced from a DNA sample, but that's just the first hurdle to overcome in bringing a species back from the dead

The population of endangered monarch butterflies wintering in Mexico's Michoacan dropped by 22% in just one year.

Everything in nature—flowering, breeding, migration—lives and dies by a clock that is being recalibrated by climate change. We don’t yet know how severe the consequences may be.

The total weight of Earth’s wild land mammals – from elephants to bisons and from deer to tigers – is now less than 10% of the combined tonnage of men, women and children living on the planet. A study by scientists at Israel’s Weizmann Institute of Science, published this month, concludes that wild land mammals alive today have a total mass of 22m tonnes. By comparison, humanity now weighs in at a total of around 390m tonnes.

Scientists studying the Permian-Triassic mass extinction find ecosystems can suddenly tip over

The possibility that communication networks of fungi exist connecting forest ecosystems in a 'wood-wide web' has increasingly gained attention among researchers in recent decades.

Thanks to the ESA, at least 227 species have been saved from extinction and 110 species have seen a tremendous recovery including American alligators, bald eagles, peregrine falcons, and humpback whales.
