WWF Living Planet Report 2024: Global Wildlife Populations Have Declined by 73%

The recently published WWF Living Planet Report 2024 highlights the alarming state of global biodiversity. The decline in animal populations is drastic and threatens the ecological balance. Vertebrate species such as mammals, birds, fish, amphibians, and reptiles have been particularly affected, with significant declines since the 1970s. Shrinking vertebrate populations

It is unclear whether it depicts an aurochs, a crossbreed between a cow and an aurochs, or a cattle breed resembling the aurochs. (© Charles Hamilton Smith, Public domain, via Wikimedia Commons)

The Return of the Aurochs as the Tauros: From Extinction Back to the Pastures

For nearly 400 years, the aurochs, or urus, the wild ancestor of all modern domesticated cattle, has been considered extinct. However, it may soon reappear in the form of the Tauros, its selectively bred successor, in the UK. According to a report by BBC Countryfile, there are plans to reintroduce

Lyall's wren went extinct less than ten years after humans settled on Stephens Island. It is considered a classic example of the extinction of an island endemic species, which had no natural defenses against invasive predators. (© Vertebrate Zoology Curator, CC0, via Wikimedia Commons)

Human-Caused Species Loss: Global Impact Far Greater Than Expected

A study published in early October in the journal Science suggests that human-caused species loss has far-reaching consequences that were previously underestimated. The scientists highlight the fact that the extinction of bird species has not only wiped out ecological roles but also billions of years of unique evolutionary history. In

Ivory-billed woodpeckers were primarily found in the southern United States. The main causes for their population decline are attributed to hunting and the loss of their habitat due to widespread deforestation.

Biotech Company Plans to Revive the Ivory-billed Woodpecker by 2025

The U.S. biotechnology company Colossal Biosciences announced on October 1st its plan to revive the ivory-billed woodpecker by 2025, amidst the ongoing debate about whether this iconic bird species is truly extinct. The ivory-billed woodpecker was once a keystone species in the forests of the southern United States, playing a

Australia: Largest Known Population of the Extremely Rare Night Parrot Discovered

An article published in September 2024 in the Journal of Wildlife Research reports the discovery of the largest known population of the night parrot (Pezoporus occidentalis) in the eastern Pilbara region of Western Australia. A team of Indigenous rangers and scientists tracked down a colony of about 50 birds –

New Study: Dwarf Hippopotamuses and Elephants in Cyprus Driven to Extinction by a Few Thousand People

New research reveals that dwarf elephants (Palaeoloxodon cypriotes) and dwarf hippopotamuses (Phanourios minor) on the Mediterranean island of Cyprus were driven to extinction after the arrival of Paleolithic humans around 14,000 years ago. A small population of possibly just 3,000 people was enough to wipe out these animals within a

Pristimantis ruidus: Frog Species Missing for 100 Years Rediscovered in Ecuador

During a 2022 expedition to the Molleturo forest in the Ecuadorian Andes, biologist Juan Sánchez-Nivicela and his team made a remarkable discovery: two tiny frogs that could not be immediately identified. Now, as the researchers report in the journal Zoosystematics and Evolution, the frogs belong to the species Pristimantis ruidus,

Taxidermied Huia Pair Expected to Fetch Up to NZ$128,000 at London Auction

A rare taxidermied pair of huia birds could fetch up to NZ$128,000 at an auction in London. Organized by Roseberys London, the auction is scheduled for October 2024. The huia pair, consisting of a male and a female, dates back to the late 19th century and is considered extremely rare.

Russia: Believed-to-be-extinct Abrau Sprat Rediscovered

In October 2019, researchers collected nine small fish during an expedition from Lake Abrau in the Krasnodar region of western Russia. Recent DNA analyses have confirmed that the captured fish are indeed the endemic Abrau sprat (Clupeonella abrau), a species that had not been recorded since 2008. Challenges for the

Mussau Triller: Lost Bird Species Rediscovered After 44 Years

The Mussau triller (Lalage conjuncta), last documented in 1979, was rediscovered in June of this year by Australian bird photographer Joshua Bergmark during a tour with a group of birdwatchers. This songbird species, part of the cuckooshrike family, is endemic to Mussau Island, located in the Bismarck Archipelago north of
