The Yangtze sturgeon lived in its namesake river for 140 million years. Now it doesn’t. Nor does another behemoth it shared China’s longest waterway with for ages, the Chinese paddlefish. Updating its Red List of Threatened Species on Thursday for the first time in 13 years, the International Union for Conservation of Nature declared the two species, known as “the last giants of the Yangtze,” extinct.

The monarch butterfly fluttered a step closer to extinction Thursday, as scientists put the iconic orange-and-black insect on the endangered list because of its fast dwindling numbers.

1 out of every 5 people around the world depend on wild species for food and income

One of the typical preconceived notions people have about artificial intelligence is fear. It is because of the prospect that in the near future, artificial intelligence will take away people's jobs and one day destroy human civilization as well.

Believed to be extinct for more than a century, a rare species of giant tortoise is in fact still alive. Scientists assumed that the chelonoidis phantasticus had died out more than a century ago. The species is better known as the ‘fantastic giant tortoise’ and is native to the Galápagos Fernandina island.

Extinction, a new book by Marc Schlossman, explores endangered and extinct species and the factors threatening them through a rare behind the scenes look at one of the most important sets of natural history collections in the world at the Field Museum in Chicago.

When Kurt Benirschke started collecting skin samples from rare and endangered animals in 1972, he didn't have a firm plan on what to do with them. As a researcher at the University of California San Diego, he believed that one day the tools would be developed to use them to save those animals. A few years later, he moved his collection to San Diego Zoo, and called it the Frozen Zoo.

Some could be lost forever, while others could live in areas difficult to reach

More than a fifth of all reptile species are threatened with extinction, which could have a “devastating” impact on the planet, a new study warns. The largest ever analysis of the state of the world’s reptiles, published in Nature, found that 21% of reptile species are facing extinction. From lizards to snakes, such a loss could have disastrous impacts on ecosystems around the world, the study says.

In response to three lawsuits brought by the Center for Biological Diversity, the U.S. Fish and Wildlife Service agreed today to dates for decisions on whether 18 plants and animals from across the country warrant protection as endangered or threatened species under the Endangered Species Act. The Service will also consider identifying and protecting critical habitat for another nine species.

They help us put food on our tables through pollination and nutrient recycling. They break down and dispose of organic waste, and are food for many animals. 

An expedition to the forests of Louisiana say extinction of bird, last definitively seen in 1944, has been exaggerated

The only halfway realistic aspect of “Jurassic Park” may be that the land was thronged with life, much of which with fangs. One can hardly generalize about the weather 200 to 145 million years ago, but the Jurassic by and large seems to have been warm and wet. The fact is that a lot of new species emerged in that time, from the lumbering stegosaurs and gigantosaurs to the earliest known proper birds – yes, your duck had ancestors back then. Tiny rodents began to emerge. In the Late Jurassic, the fearsome allosaurus arose too. And no, it isn’t a T-rex.

International conservation groups are calling on countries in the Global North to provide billions more dollars every year to protect the world’s biodiversity. “The future of humanity is literally at stake. People are destroying and consuming nature at devastating rates,” Patricia Zurita, the CEO of BirdLife International, said at a virtual press conference on March 1. “Wealthy countries must support and agree to a target of providing at least 60 billion US dollars annually for international finance for biodiversity to developing countries.”

No recovery plan for the Australian marsupial was in place despite it being identified as a requirement nine years ago

Freshwater mussels are dying suddenly and in the thousands, with each mass death event bringing these endangered molluscs closer to extinction. Tragically, these events rarely get noticed. In March last year, for example, seawater was introduced into the lower Vasse River in south-western Australia to control harmful algal blooms. This killed the entire population of Carter's freshwater mussel (Westralunio carteri) in this section of the river.

A human-driven mass extinction “has begun on land and in freshwater seems increasingly likely,” according to a new article.

Recorded over four decades, the calls of 53 native birds were gathered on an album raising funds and awareness for species facing extinction

Research shows introduced pest plants and animals are costing the country $25bn a year.

Factors behind disappearances include too much development, water pollution, logging and competition from invasive species
