‘Gamechanging’ £10m environmental DNA project to map life in world’s rivers

eBioAtlas programme aims to identify fish, birds, amphibians and land animals in freshwater systems from the Ganges to the Mekong

Concealed by the turbid, swirling waters of the Amazon, the Mekong and the Congo, the biodiversity of the world’s great rivers has largely remained a mystery to scientists. But now a multimillion-pound project aims to describe and identify the web of life in major freshwater ecosystems around the world with “gamechanging” DNA technology.

The International Union for Conservation of Nature (IUCN) and UK-based environmental DNA (eDNA) specialists NatureMetrics have launched a partnership to take thousands of water samples from freshwater river systems like the Ganges and the Niger delta to identify the fish, birds, amphibians and land animals that live in and around them.

Finding fangs: new film exposes illicit trade killing off Bolivia’s iconic jaguar

Undercover documentary investigates the trafficking of Latin America’s big cat to meet demand in China

Elizabeth Unger was a 25-year-old biology graduate working as a PhD research assistant for big cat and climate projects in Latin America when she heard about the Bolivian authorities intercepting dozens of packages containing jaguar fangs sent by Chinese citizens to addresses in China.

“I was really blown away as [the story] was completely under the radar,” she says. Six years later, she is making her directorial debut with a film about the trade, which is contributing to a decline in the population of Latin America’s iconic big cat.

We are running out of time to reach deal to save natural world, says UN talks chair

Warning comes amid fears of further delays to Kunming summit, which aims to agree on curbing destruction of ecosystems

The world is running out of time to reach an ambitious deal to stem the destruction of the natural world, the co-chair of negotiations for a crucial UN wildlife summit has warned, amid fears of a third delay to the talks.

Negotiators are scheduled to meet in Kunming, China, in October for Cop15, the biggest biodiversity summit in a decade, to reach a hoped-for Paris-style agreement on preventing wildlife extinctions and the human-driven destruction of the planet’s ecosystems.

‘A huge surprise’ as giant river otter feared extinct in Argentina pops up

Conservationists thrilled at the sighting of the wild predator, last seen in the country in the 1980s

“It was a huge surprise,” said Sebastián Di Martino, director of conservation at Fundación Rewilding Argentina. “I was incredulous. An incredible feeling of so much happiness. I didn’t know if I should try to follow it or rush back to our station to tell the others.”

The cause of the excitement was the sighting, last week, of a wild giant river otter – an animal feared extinct in the country due to habitat loss and hunting – on the Bermejo River in Impenetrable national park, in north-east Argentina’s Chaco province. The last sighting of a giant otter in the wild in Argentina was in the 1980s. On the Bermejo, none have been seen for more than a century.

Climate crisis behind drastic drop in Arctic wildlife populations – report

Native shorebirds and caribou among species at risk as survival strategies are upended

A drastic drop in caribou and shorebird populations is a reflection of the dire changes unfolding on the Arctic tundra, according to a new report from the Arctic Council.

The terrestrial Arctic spans approximately 2.7m sq miles (7m sq km), marked by extreme cold, drought, strong winds and seasonal darkness. Species living in this environment have adapted to thrive in the harsh conditions. But the climate crisis has upended such survival strategies, according to the State of the Arctic Terrestrial Biodiversity report, published by the council’s Conservation of Arctic Flora and Fauna (Caff) working group.

Campaigners lose court case to stop Ugandan forest clearance

Court ruling gives go-ahead for sugar plantation in Bugoma forest, home to endangered chimpanzees

Conservationists in Uganda have condemned as “shallow and absurd” a court ruling that authorised the government to allow swathes of a tropical forest to be cleared for a sugar-cane plantation.

Three environmental groups had taken the government to court over a decision to allow Hoima Sugar Ltd to build on 5,500 hectares (13,500 acres) in the Bugoma Forest Reserve.

Iguanas with chips: Florida seeks solution to invasive reptile problem

  • ‘Tag day’ initiative opposed by some owners of exotic pets
  • State official ‘proud that Florida is looked at as a leader’

From Key West’s high-summer Hemingway Days, in which bearded hopefuls vie for the title of best Papa lookalike, to the annual hunt for the elusive (and imaginary) skunk ape, Florida is renowned for its calendar of curiosities.

It’s inspiring hope and change – but what is the IUCN’s green list?

The red list of species at risk is well-known, but the list for protected sites is quietly helping to ‘paint the planet green’

When Kawésqar national park was formed in the Chilean part of Patagonia in 2019, just one ranger was responsible for an expanse the size of Belgium. Its fjords, forests and Andean peaks are a precious wilderness – one of the few remaining ecosystems undamaged by human activity, alongside parts of the Amazon, the Sahara and eastern Siberia.

Chilean officials hope that Kawésqar will, one day, meet the high standards for protected areas laid out by the International Union for Conservation of Nature (IUCN) and make it on to the organisation’s “green list”.

Spain’s Endesa power firm sued over electrocution of birds

Landmark case says thousands of birds including endangered eagles die needlessly each year

In Leonard Cohen’s famous song, a bird on a wire is a symbol of freedom, but for thousands of birds it is the equivalent of being sent to the electric chair.

Now, in a landmark case, a Spanish electricity company is being prosecuted over the deaths of hundreds of birds electrocuted on pylons and overhead cables and for failing to comply with regulations designed to protect wildlife.

Rewilding our cities: beauty, biodiversity and the biophilic cities movement

Buildings covered in plants do more than just make the cityscape attractive – they contribute to human wellbeing, biodiversity, and action on climate change

Our cities are dominated by glass-faced edifices that overheat like greenhouses then guzzle energy to cool down. Instead, we could have buildings that are intimately connected to the living systems that have evolved with us, that celebrate the human-nature connection that is central to our wellbeing.

As more of us in Australia live in urban areas and our cities grow, bringing nature into our cities is a key part of establishing and rebuilding that connection. As well as bringing beauty into urban environments, we know that people are healthier when they are connected to nature. Research also shows that crime rates decrease in areas with street trees and that property values increase.

Endangered North Atlantic right whales produce most calves since 2015

  • Scientists caution high death rate is outpacing births
  • Population of whales estimated at around 360

North Atlantic right whales gave birth over the winter in greater numbers than scientists have seen since 2015, an encouraging sign for researchers who became alarmed three years ago when the critically endangered species produced no known offspring at all.

Can red wolves come back from the brink of extinction again?

Once a US conservation success story, numbers in the wild have plummeted. Now a court has given hope for their survival

There are perhaps no more than 10 red wolves left in the wild, and they are all in just one place: North Carolina.

It is an astonishing statistic for a species once hailed as undergoing the most successful reintroduction programme in the US, providing the blueprint for Yellowstone national park’s much-lauded grey wolf rewilding project.

Tiny frog species among series of finds in Andean ‘sky islands’

‘Ecological Swat team’ discovers 20 unknown species in Bolivia including viper and butterfly

An “ecological Swat team” has discovered 20 previously unknown species in the misty cloud forests and cascading waterfalls that flank Bolivia’s Zongo valley.

Among the animals found were a minuscule 10mm-long frog, a pit viper, two metalmark butterflies and an adder’s-mouth orchid. The pristine forests are just 30 miles (48km) from the capital, La Paz, but the expedition also rediscovered the devil-eyed frog, seen just once before, and a satyr butterfly not seen for nearly a century. Alongside these were threatened species including the spectacled bear and the channel-billed toucan.
