Near-blind Ansell’s mole-rats detect magnetic cues with eyes, study shows

Research shows Zambian species with surgically removed eyes change nest-building habits but other behaviours remain intact

Near-blind, underground-burrowing, African Ansell’s mole-rats can sense magnetic fields with their eyes, a study has found.

Native to Zambia, the animals have eyes that span just 1.5mm in diameter, live in elaborate underground tunnel systems of up to 1.7 miles (2.8km) long and feed on plant tubers and roots.

Swearing parrots separated after telling folk where to go

Five African grey parrots at a Lincolnshire zoo believed to be a bad influence on each other

Five foul-mouthed parrots have been separated after learning to swear at a Lincolnshire zoo.

The parrots – named Billy, Elsie, Eric, Jade and Tyson – joined Lincolnshire Wildlife Park’s colony of 200 grey parrots in August. But soon after, they started encouraging each other to swear.

How Tunisia’s shrinking economy and fish stocks put shark on the menu

A lack of awareness and ever-increasing competition among fishing boats threaten one of the sea’s most vital species

The temperature is cooling down in the fish market in Monastir, Tunisia. Still, the suffocating smell of the fish guts that have sat through the full force of the day’s heat hangs heavy in the air. The stallholders have left now, but on the floor amid the detritus is the unmistakable shape of a severed shark’s head.

Nearby, in a skip, the bodies of two guitarfish rays lie discarded, stripped of meat to the cartilage.

‘Shocking’: wilderness the size of Mexico lost worldwide in just 13 years, study finds

Researchers say loss of 1.9m square kilometres of intact ecosystems will have ‘profound implications’ for biodiversity

Wilderness across the planet is disappearing on a huge scale, according to a new study that found human activities had converted an area the size of Mexico from virtually intact natural landscapes to heavily modified ones in just 13 years.

The loss of 1.9m square kilometres (735,000 sq miles) of intact ecosystems would have “profound implications” for the planet’s biodiversity, the study’s authors said.

Berejiklian warns Nationals against further public posturing over koala protection policy

NSW premier implores John Barilaro to stick to agreement after he refused to rule out further threats to dismantle the Coalition

The New South Wales premier, Gladys Berejiklian, has made it clear she will not tolerate any further public posturing by the Nationals over koala habitat protections or new threats by the junior partner to leave the Coalition.

Berejiklian on Thursday also implored her Liberal colleagues to move on and refocus on their jobs following last week’s near split in the government, brought on by the Nationals leader, John Barilaro, threatening to move to the crossbenches with his MPs.

‘Sit! sit!’ How one Australian dealt with a 4m crocodile called ‘Bonecruncher’

Matt Wright – known as ‘the outback wrangler’ – came across the large reptile while clearing logs in a river path in the Northern Territory

For most people, the sight of an approaching crocodile, mouth wide open, would provide the fright of a life. And their fear would be rightly placed, as encounters between man and saltwater crocs typically have deathly ends for the former.

Not for Matt Wright, the so-called “outback wrangler”.

World fails to meet a single target to stop destruction of nature – UN report

‘Humanity at a crossroads’ after a decade in which all of the 2010 Aichi goals to protect wildlife and ecosystems have been missed

The world has failed to meet a single target to stem the destruction of wildlife and life-sustaining ecosystems in the last decade, according to a devastating new report from the UN on the state of nature.

From tackling pollution to protecting coral reefs, the international community did not fully achieve any of the 20 Aichi biodiversity targets agreed in Japan in 2010 to slow the loss of the natural world. It is the second consecutive decade that governments have failed to meet targets.

Dolphin numbers up in Hong Kong after Covid crisis halts ferries

Revival prompts calls to divert boats to help protect native Indo-Pacific humpbacks

Large numbers of dolphins returned to Hong Kong waters within weeks of the Covid-19 crisis shutting down high-speed ferries, and researchers are now calling for protections before the ferries resume.

Indo-Pacific humpback dolphins, also known as Chinese white dolphins and pink dolphins, are native to the Pearl River estuary, but typically avoided the waters between Hong Kong and Macau because of the high volume of high-speed boats.

‘Lost decade for nature’ as UK fails on 17 of 20 UN biodiversity targets

UK government said it failed on two-thirds of targets, but RSPB analysis is bleaker – and suggests UK is moving backwards in some areas

The UK has failed to reach 17 out of 20 UN biodiversity targets agreed on 10 years ago, according to an analysis from conservation charity RSPB that says the gap between rhetoric and reality has resulted in a “lost decade for nature”.

The UK government’s self-assessment said it failed on two-thirds of targets (14 out of 20) agreed at the Convention on Biological Diversity (CBD) in Nagoya, Japan, in 2010, but the RSPB analysis suggests the reality is worse. On six of the 20 targets the UK has actually gone backwards. The government’s assessment published last year said it was not regressing on any target.

‘I’ve never seen or heard of attacks’: scientists baffled by orcas harassing boats

Reports of orcas striking sailing boats in the Straits of Gibraltar have left sailors and scientists confused. Just what is causing such unusually aggressive behaviour?

When nine killer whales surrounded the 46ft boat that Victoria Morris was crewing in Spain on the afternoon of 29 July, she was elated. The biology graduate taught sailing in New Zealand and is used to friendly orca encounters. But the atmosphere quickly changed when they started ramming the hull, spinning the boat 180 degrees, disabling the autohelm and engine. The 23-year-old watched broken bits of the rudder float off, leaving the four-person crew without steering, drifting into the Gibraltar Straits shipping lane between Cape Trafalgar and the small town of Barbate.

Scientists baffled by orcas ramming sailing boats near Spain and Portugal

From the Strait of Gibraltar to Galicia, orcas have been harassing yachts, damaging vessels and injuring crew

Full story: ‘I’ve never seen or heard of attacks’ – scientists baffled by orcas harassing boats

Scientists have been left baffled by incidents of orcas ramming sailing boats along the Spanish and Portuguese coasts.

In the last two months, from southern to northern Spain, sailors have sent distress calls after worrying encounters. Two boats lost part of their rudders, at least one crew member suffered bruising from the impact of the ramming, and several boats sustained serious damage.

Up to 48 species saved from extinction by conservation efforts, study finds

Extinction rates for birds and mammals since 1993 would have been ‘three to four times higher’ without action

Up to 48 bird and mammal extinctions have been prevented by conservation efforts since a global agreement to protect biodiversity, according to a new study.

The Iberian lynx, California condor and pygmy hog are among animals that would have disappeared without reintroduction programmes, zoo-based conservation and formal legal protections since 1993, research led by scientists at Newcastle University and BirdLife International found.

Hummingbird’s temperature can fall to 3.3C at night to preserve energy

Researchers in Andes find temperature a record for all birds and non-hibernating mammals

Hummingbirds have scooped another record: they are not only tiny but can reach body temperatures below that of any non-hibernating mammal and any other bird.

The hummingbird is among a number of small creatures, including certain bats, that can enter a state known as daily torpor, a phenomenon where they turn down their metabolism and body temperature to save energy.

Chinese mining firms in Zimbabwe pose threat to endangered species, say experts

Two companies granted permission to clear land at Hwange national park, home to cheetahs, elephants and rhinos

Rhinos, giraffes, cheetahs and other endangered species face a new threat in Zimbabwe’s Hwange national park: Chinese mining companies.

Zhongxin Coal Mining Group and Afrochine Smelting have received permission from the government to begin environmental impact assessments for drilling, land clearance, road building and geological surveys at two proposed sites inside the park, which is home to almost 10% of Africa’s remaining wild elephants.
