Hedgehogs ‘near threatened’ on red list after 30% decline over past decade

Posted on by

The mammals were once common across Europe but urban development has pushed them towards extinction

Hedgehogs are now listed as “near threatened” on the International Union for Conservation of Nature’s red list after a decline in numbers of at least 30% over the past decade across much of their range.

While hedgehogs were once common across Europe, and were until now listed as of “least concern” on the red list, they are being pushed towards extinction by urban development, intensive farming and roads, which have fragmented their habitat.

Crocodile dies after chewing on electric wire after being ‘attracted’ to it

The 10-year-old male Cuban crocodile at the Smithsonian zoo in Washington, DC, likely bit on electrical equipment in its enclosure

An endangered crocodile in a Smithsonian zoo in the US died after apparently biting into a live electrical cord in its shelter.

The Cuban crocodile, a 10-year-old male reptile, was discovered on 17 December inside its enclosure by staff at the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI)’s Reptile Discovery Center in Washington, DC.

Boom time for Cape Verde’s sea turtles as conservation pays off

Posted on by

The number of nesting sites on the archipelago has risen dramatically, but global heating sees male population plummet

It’s nearly midnight as Delvis Semedo strolls along an empty beach on the Cape Verdean island of Maio. Overhead, the dense Milky Way pierces the darkness. A sea turtle emerges from the crashing waves and lumbers up the shore. Then another. And another.

Semedo is one of about 100 local people who patrol Maio’s beaches each night during nesting season to collect data on the turtles and protect them from poachers. This year has been busier than usual. Sea turtle nests on the islands of Sal, Maio and Boa Vista – the primary nesting grounds for loggerheads in Cape Verde – have soared in the last five years. Cape Verde’s environment ministry puts nest numbers in 2020 across all 10 islands at almost 200,000, up from 10,725 in 2015.

Third of shark and ray species face extinction, warns study

Posted on by

Number of species of sharks, rays and chimaeras facing ‘global extinction crisis’ doubles in a decade

A third of shark and ray species have been overfished to near extinction, according to an eight-year scientific study.

“Sharks and rays are the canary in the coalmine of overfishing. If I tell you that three-quarters of tropical and subtropical coastal species are threatened, just imagine a David Attenborough series with 75% of its predators gone. If sharks are declining, there’s a serious problem with fishing,” said the paper’s lead author, Prof Nicholas Dulvy, of Canada’s Simon Fraser University.

‘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.

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

Posted on by

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”.

European hamster and caterpillar fungus on brink of extinction

Update to IUCN red list warns of hamster’s falling birth rate and high demand for fungus

Hamsters and fungi may not be poster species among those threatened with extinction but are no less important in ecosystems, according to an updated list of the world’s most fragile species.

The European hamster once scurried across much of Europe and Russia but has now vanished from most of its original range and on current trends will go extinct within 30 years, according to the update of the IUCN red list, the global database of species on the brink.

Biologists discover single female Wallace’s giant bee inside a termites’ nest in a tree

As long as an adult thumb, with jaws like a stag beetle and four times larger than a honeybee, Wallace’s giant bee is not exactly inconspicuous.

But after going missing, feared extinct, for 38 years, the world’s largest bee has been rediscovered on the Indonesian islands of the North Moluccas.
