Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury.

There are relatively few snow leopards in the world, and it has likely been that way for a long time, a new study indicates.

New research shows that marine heatwaves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean’s ability to buffer against climate change.

They are microscopic, yet they play a gigantic role in the climate system: the tiny microalgae collectively known as phytoplankton.

Trawling restrictions not only benefits fish and shellfish; anemones and corals are also becoming more common, according to a new study from the University of Gothenburg. 

A new international study involving researchers from the University of Gothenburg shows that vegetation in the Arctic is changing rapidly as species from nearby forests spread into the tundra. 

An enormous but poorly understood region of the global ocean–referred to as the abyssal benthic boundary layer–lies a few meters above the seafloor and has only been sampled a handful of times.

Average tree size across the Amazon has increased by 3.2% every decade consistent with a response to rising carbon dioxide levels, a new study suggests. 

Corals, the foundation of ocean biodiversity, are threatened by climate change. But new research suggests that these organisms might be more resilient than previously thought.

Hawaiʻi’s ecosystems and agriculture face growing threats from invasive species, with about 20 new insects and 100 new plants arriving each year, undermining the islands’ ecological, cultural and economic foundations.
