Mediterranean monk seals are among the rarest pinnipeds in the world.

Mediterranean Monk Seals Hide in Underwater ‘Bubble Caves’ to Avoid Tourists During the Busy Summer Season, a Study Suggests

Researchers caught the rare pinnipeds resting and sleeping in a secluded chamber on the Greek islet of Formicula. The findings suggest that these small caves should be included in efforts to protect the animals’ habitat

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos

Artist's reconstruction of newly described koala species. 

A Dimpled Koala Fossil Found in a Cave in Western Australia Revealed Why This Previously Unknown Species Went Extinct

The new study found that they lost their arboreal habitat due to a drying climate, a dire warning for the modern-day marsupials that face a similar threat

This Socorro dove recently hatched at the San Diego Zoo Safari Park. Conservationists have been undertaking a decades-long effort to breed the extinct-in-the-wild species and one day reintroduce it to its native Socorro Island in Mexico.

New, Rare Dove Hatchlings Are a ‘Source of Hope’ for the Extinct-in-the-Wild Birds and a Step Forward in the Ambitious Project to Save Them

The Socorro dove has not been recorded in the wild since 1972, but that could change within only a few years, conservationists say, thanks to a long-term reintroduction effort

Sue Schubel hand-paints around 500 a year from her workshop in a converted barn steps from the ocean in Bremen, Maine, a tiny town in the lower third of the state’s craggy coast.

How ‘Seabird Sue’ Blends Art and Science to Attract Birds Back to Lost Habitat

For the past decade, Sue Schubel has been making detailed decoys of terns, puffins and other seabirds to entice real ones to restored or new homes

The past, present and future of the giant bovine are front and center in a new exhibition as the country approaches its 250th birthday

What if, rather than coral reef rehabilitation remaining a tedious and difficult manual process, conservationists could harness robotics, artificial intelligence and autonomous vehicles to transform it into an industrial-scale endeavor?

Could Underwater Autonomous Robots Save Coral Reefs?

Reef restoration is a slow process, with divers planting coral fragments one at a time by hand. But roboticists are now developing automated planters that could change the game

The Tees Transporter Bridge was a feat of engineering but has been closed due to structural concerns since 2019.

These Are the Top Ten ‘Endangered’ Buildings and Bridges in England and Wales—and They Tell Us a Lot About Life in the Victorian Era

Structures remaining from the height of the British Empire reveal changing economic, medical and education trends from the 1800s and early 1900s. But their legacy is at risk as they fall into disrepair

An intrepid male orangutan crosses an artificial bridge connecting trees on either side of a public road.

A public road in Indonesia separates forests housing about 350 wild orangutans, among other animals. So, conservationists built several canopy bridges to prevent habitat fragmentation

Volunteers have played a vital role in SERC's Functional Forests project. They've helped plant trees, put up deer fencing and mapped the tree locations with bamboo stakes, among other duties.

The Planet Needs Prosperous Forests. These Scientists Are Planting More Than 33,000 Trees to Find the Perfect Species Blends

Forests provide myriad benefits, including timber, wildlife attraction, local cooling and climate resilience. At the Smithsonian Environmental Research Center, ecologists are testing which tree combinations might create flourishing woodlands

Western monarch butterflies bask in the sun on a eucalyptus branch at Lighthouse Field State Beach. In December 2025, researchers placed ultralight radio tags on some monarchs at this site, hoping to track their movements and identify areas to prioritize for the species’ conservation.

Butterflies Are in Dramatic Decline Across North America. A Close Look at the Western Monarch Shows Why

Pesticides, habitat loss and climate change have taken their toll on the beloved insects. But the experts working with them still find hope for their future

The monkeys sometimes steal food from tourists.
