Saudi Arabia’s Prince Mohammed bin Salman Royal Reserve has reintroduced the Arabian hare (Lepus capensis arabicus) to be the 14th native species returned to the reserve since the ReWild Arabia program began in winter 2022, reported the Saudi Press Agency on Sunday.

The reintroduction of this primary consumer supports the re-establishment of a critical layer of the trophic food web, restoring energy pathways from vegetation to predators. It also supports the recovery of ecosystem functioning at the landscape scale.

Arabian hares sit at a crucial link in the food chain, influencing ecosystem processes both up and down the trophic pyramid. As herbivores, they graze and disperse seeds, helping to regulate vegetation across the reserve’s ecosystems. For desert predators, they are a principal food source, transferring energy upward from scarce desert plant biomass with a high ectotrophic efficiency, sustaining higher-level wildlife.

Reserve CEO Andrew Zaloumis said: “True rewilding restores processes, not just populations. By bringing back the Arabian hare - a keystone prey for the Prince Mohammed bin Salman Royal Reserves' jackals, foxes, wildcats and hyenas, and ecosystem shaper - we strengthen the connections that allow desert life to recover and flourish. This is the foundation of ReWild Arabia.”

Twenty Arabian hares, carefully selected to boost genetic diversity, have been introduced through the reserve’s rewilding program. Due to their ecological significance, the animals will initially remain in purpose-built breeding enclosures to accelerate population growth before release. The first leveret (hare young) has already been born. These introductions will strengthen the reserve’s existing sparse population by increasing numbers and diversifying genetics.

Unlike many desert species that retreat underground to escape extreme heat, Arabian hares are uniquely adapted to life on the land’s surface, hence their other name, the desert hare. They are among the few mammals able to survive extreme temperatures without burrowing.

Their cryptic coloration provides effective camouflage, reducing detection by predators. Large ears, which can reach up to 17 centimeters in length, 30% of their total body length, act as efficient cooling systems and provide acute hearing, with pinnae capable of rotating independently. Combined with near-360-degree vision, these adaptations enable early detection of predators.

When threatened, Arabian hares can reach speeds of up to 80 kilometers per hour, zig-zagging sharply to evade pursuit. Despite these defenses, predation rates in desert environments can reach up to 90 percent, underscoring their importance as a primary prey species.

Since the ReWild Arabia program began, 14 species have been successfully reintroduced. The Arabian hare marks the sixth species to breed within the program. To date, the reserve has recorded over 100 sand gazelle births, 19 mountain gazelle births, the first two Nubian ibex kids, 36 Arabian oryx calves, and a Persian onager foal.

These milestones reflect the reserve’s long-term objective: to establish self-sustaining wildlife populations and build founder populations capable of supporting restoration efforts across Saudi Arabia and the wider region.

Large-scale rewilding across the reserve is guided by its Integrated Development Management Plan, which delivers habitat-wide restoration across 24,500 square kilometers of marine and terrestrial ecosystems. Supported by an advanced ranger program and strong community engagement, this work advances Vision 2030 and the Saudi Green Initiative, contributing to national commitments to restore biodiversity and protect 30% of the Kingdom’s land and sea by 2030.

The 24,500 km² Prince Mohammed bin Salman Royal Reserve stretches from the lava plains of the Harrats to the deep Red Sea in the west, connecting NEOM, Red Sea Global, and AlUla. It is home to the magnificent Wadi al-Disah and Red Sea Global’s AMAALA destination.

The reserve encompasses 15 distinct ecosystems. At just 1% of the Kingdom’s terrestrial area and 1.8% of its marine area, it boasts over 50% of the Kingdom’s species, making it one of the most biodiverse protected areas in the Middle East.

The reserve is committed to restoring and conserving the natural and cultural environment. This includes the reintroduction of 23 historically occurring native species, 14 of which have already been reintroduced, including the Arabian oryx, Persian onager, sand gazelle and mountain gazelle, as part of a wide-ranging rewilding program.

The Prince Mohammed bin Salman Royal Reserve is overseen by the Royal Reserves Council, chaired by Prince Mohammed bin Salman, Crown Prince and Prime Minister. Its program is integrated with Saudi Arabia’s wider sustainability and conservation programs, including the Saudi Green and Middle East Green Initiatives.

Brazilian scientists have identified a new species of giant dinosaur with ties to a similar animal found in Spain, reinforcing knowledge that land routes once connected parts of South America, Africa and Europe about 120 million years ago.

Named Dasosaurus tocantinensis, the species is one of the biggest found in the South American country and was described this month in the Journal of Systematic Palaeontology, Reuters reported.

The fossils were uncovered in 2021 at a site hosting infrastructure works near Davinopolis, in Brazil's northeastern state of Maranhao, and the research was led by Elver Mayer of the Federal University of the Sao Francisco Valley.

The remains include a femur measuring about 1.5 meters (59 inches), which helped researchers estimate the animal stretched roughly 20 meters long.

"As the excavation progressed over the days, we began to see the evidence of that huge bone, which is the femur," said Leonardo Kerber, a paleontologist at the Federal University of Santa Maria (UFSM) who contributed to the research.

"This indicates it was a very large dinosaur. Today we know Dasosaurus is among the biggest dinosaurs ever found in Brazil," he noted.

According to UFSM, analysis indicated the species is the closest known relative of Garumbatitan morellensis, a dinosaur described in Spain.

Their lineage was European and may have dispersed into what is now South America roughly 130 million years ago, likely via northern Africa, before the Atlantic fully opened, the university said.

Dasosaurus tocantinensis's name combines references to the region where the dinosaur was found, including the Tocantins River, a major waterway whose eastern margins lie near the fossil site.

The German philosopher Jurgen Habermas has died, a spokesperson for his publishing house, Suhrkamp Verlag, told AFP on Saturday.

He died at the age of 96 in Starnberg, in southern Germany, she said, citing information from the family of the politically engaged theorist.

Habermas was considered the most influential German philosopher of his generation, involved in all the major postwar debates and seeing a united Europe, in his view, as the only remedy for the rise of nationalism, AFP reported.

In his later years, he devoted himself to promoting a federal European project and prevent the continent from falling, as it did in the 20th century, into nationalist rivalries.

Throughout his life, Habermas linked philosophy and politics, thought and action.

After serving as the voice of German student protest in the 1960s, he became its target thirty years later while warning of the risks of "left-wing fascism".

In 1989, he criticised the terms of German reunification, guided essentially by the demands of the market, and which made "the Deutsche mark its standard."

Born on June 18, 1929 in Duesseldorf, Habermas had been enrolled in the Hitler Youth, but he was too young to have taken an active part in the war. As a teenager, he was deeply marked by the collapse of Nazism.

Research Reveals Decades-Long Silverpit Crater Triggered by Tsunami 40 Million Years Ago

A long-running dispute about the origin of a North Sea crater has finally been settled, as new research finds a massive asteroid hit the water and triggered a towering tsunami millions of years ago.

Scientists have found that the Silverpit Crater – which lies around 700 meters beneath the southern North Sea seabed, roughly 80 miles off the coast of Yorkshire – was formed when an asteroid or comet struck the region roughly 43 to 46 million years ago, sparking a 330 feet tsunami.

Since geologists first identified the formation in 2002, the 3km-wide crater and its surrounding ring of circular faults spanning about 20 km have sparked intense debate, according to The Independent.

But researchers say their new study marks the clearest evidence yet that the structure is one of Earth’s rare impact craters.

This confirmation places it in the same category as well-known structures such as the Chicxulub Crater in Mexico, which is linked to the dinosaur mass extinction.

The team used computer modelling and analyzed newly available seismic imaging and microscopic geological samples taken from beneath the seabed.

Dr. Uisdean Nicholson, a sedimentologist in Heriot-Watt University’s School of Energy, Geoscience, Infrastructure and Society, who led the investigation, said: “New seismic imaging has given us an unprecedented look at the crater.”

He said samples from an oil well in the area also revealed rare ‘shocked’ quartz and feldspar crystals at the same depth as the crater floor.

“We were exceptionally lucky to find these – a real ‘needle-in-a-haystack’ effort. These prove the impact crater hypothesis beyond doubt, because they have a fabric that can only be created by extreme shock pressures,” said Nicholson.

The scientists say these microscopic minerals form only under the extreme pressures generated during asteroid impacts, providing strong confirmation of the event.

Early research proposed that the feature was created by a high-speed asteroid impact. Supporters of that idea pointed to its round shape, central peak, and surrounding concentric faults, which are often seen in known impact craters.

But other scientists suggested different explanations. Some proposed that underground salt movement distorted the rock layers and created the structure.

Others argued that volcanic activity may have caused the seabed to collapse.

In 2009, geologists even voted on the issue. According to a report in the December 2009 issue of Geoscientist magazine, most participants rejected the asteroid impact explanation at the time.

The latest findings, published in the journal Nature Communications and funded by the Natural Environment Research Council (NERC), now appear to overturn that conclusion.

Dr. Nicholson said: “Our evidence shows that a 160-meter-wide asteroid hit the seabed at a low angle from the west.”

“Within minutes, it created a 1.5 km high curtain of rock and water that then collapsed into the sea, creating a tsunami over 100 meters high.”

The impact would have produced a violent explosion at the seafloor and sent enormous waves spreading across the region.

Professor Gareth Collins, of Imperial College London, who attended the 2009 debate about the crater’s origin and contributed to the new research, said the researchers have “finally found the silver bullet” to end the debate.

He said: “I always thought that the impact hypothesis was the simplest explanation and most consistent with the observations.”

“It is very rewarding to have finally found the silver bullet. We can now get on with the exciting job of using the amazing new data to learn more about how impacts shape planets below the surface, which is really hard to do on other planets,” Collins added.

Dr. Nicholson also expressed his excitement about using the new findings for further research into asteroids.

“Silverpit is a rare and exceptionally preserved hypervelocity impact crater,” he said.

“These are rare because the Earth is such a dynamic planet – plate tectonics and erosion destroy almost all traces of most of these events.”
