Australian ants stopping greenhouse gaseses?

From the University of South Australia:

Sugar ants’ preference for urine may reduce greenhouse gas emissions

February 6, 2020

An unlikely penchant for urine is putting a common sugar ant on the map, as new research from the University of South Australia shows their taste for urine could play a role in reducing greenhouse gases.

Led by wildlife ecologist Associate Professor Topa Petit, the Kangaroo Island-based research found that sugar ants prefer urine over sugar — the food source after which they’re named — nocturnally foraging on it to extract nitrogen molecules, some of which could end up in the greenhouse gas, nitrous oxide.

The Australian-first study compared the behaviours of sugar ants (Camponotus terebrans) as they were exposed to different concentrations of urine (human and kangaroo ~ 2.5 per cent urea), sugar water (20 per cent and 40 per cent), and urea in water (at 2.5 per cent; 3.5 per cent; 7 per cent and 10 per cent), finding that sugar ants were most attracted to higher concentrations of urea, mining them for long periods within a dry sand substrate.

While other ants are known to be attracted to urine, this is the first time that ants have been observed mining dry urine from sand, and for a long period of time.

Assoc Prof Petit says the curious discovery could play a role in nitrogen cycling.

“When I first noticed the ants swarming to scavenge urine, it was purely by accident. But under research conditions we found that the ants determinedly mined urea patches night after night with greater numbers of ants drawn to higher urea concentrations,” Assoc Prof Petit says.

“Camponotus terebrans are undoubtedly looking for urea in urine because, similar to certain other ant species, a bacterium in their digestive tract allows them to process urea to get nitrogen for protein.

“This remarkable ability to extract urea from dry sand not only shows how sugar ants can survive in arid conditions, but also, how they might reduce the release of ammonia from urine, which leads to the production of nitrous oxide, a highly active greenhouse gas.”

Nitrous oxide (NO2) is a greenhouse gas 300 times more potent than carbon dioxide. And while less abundant than carbon dioxide emissions, its presence in the atmosphere has increased substantially over the past decade, accelerated mostly by the widespread use of fertilisers.

Assoc Prof Petit says that while there is still a lot to learn about the foraging behaviours of sugar ants, the study shows a symbiotic relationship between ants and vertebrates such as kangaroos in dry environments, and evidence of the nitrogen cycle at work.

“The ability of sugar ants to thrive in dry, sandy environments and use sources of nitrogen that may not be available to other species is impressive. It may give them a competitive advantage by allowing them to feed more offspring and therefore increase their numbers,” Assoc Prof Petit says.

“Researchers working on ants as bio-indicators on grazed and ungrazed lands should take ants’ ability to process urea into account, because large amounts of urine will probably affect the assortment of ant species in the area. It would also be interesting to investigate how much ants may modify the urine ammonia volatilises from paddocks.

“This is not the last we will hear about these sugar ants — they could open up a whole new field of research.”

Bushfires kill Kangaroo island humans, kangaroos, others

This 4 January 2020 video from Australia is called Kangaroo Island fires continue as locals count cost of damage to infrastructure, animals | ABC News.

This 30 December 2019 video says about itself:

Volunteers struggle to save wild animals from Australia fires

There are no official counts or estimates of how wildlife has been affected by the deadly bushfires in Australia that have destroyed more than 4 million hectares (9.9 million acres) in five states since September. The fire and heat are either killing the native fauna such as kangaroos, wallabies, wombats and echidnas, or driving them out of the bushland and into peoples homes.

Translated from Dutch NOS radio today:

“The fire went so fast, the animals had no chance”

“Your heart is breaking. It was really devastating.”

Although it is not yet possible to record the exact extent of the damage, it is already clear that the unique nature on the Australian Kangaroo Island has suffered greatly from the wildfires. The island, slightly larger than the Dutch province of Noord-Brabant, is popular with eco-tourists.

Hundreds of kangaroo and sheep carcasses can be seen on images and many habitats of rare species have been lost.

“The fire moved so fast that most animals had no chance,” says ecologist Pat Hodgens in Australian media. “Only by chance, some habitats may have been spared. Let’s hope so.”

A 78-year-old travel guide and his 43-year-old son died on the island when they were caught up in their car by the flames. A total of 24 people died in the fires throughout Australia and an estimated 500 million birds, mammals and reptiles died.

In addition to the many kangaroos that give the island its name, there was also a large koala population, which, unlike the animals on the mainland, was not yet plagued by a persistent chlamydia infection. After the fires, a game park on the island currently handles eighteen specimens, but has had to finish off many more. Shepherds have also euthanised hundreds of wounded sheep.

In addition, there is serious concern about, eg, the endangered marsupials, bandicoots, protected glossy black cockatoos and vulnerable Kangaroo Island dunnarts on the island. The eight game cameras that were used to monitor the latter species were lost in the flames, which means that the 300 animals were probably burned.

“Even if there are survivors, there is no food for them now,” ecologist Heidi Groffen sighs to AP. “We hope to catch a few before they are completely gone.”

Gray-headed flying foxes

One of the centers that takes care of injured animals is the Australia Zoo, founded by the world-famous conservationist Steve Irwin.

His daughter informed via Instagram that the animal park itself is not threatened by the flames and that 90,000 animals have already been treated. Among them is also a whole colony of gray-headed flying foxes that were in a rescue center that was in danger of catching fire.

Our @AustraliaZoo Wildlife Hospital takes in animals from all over Australia. Hundreds of grey-headed flying foxes, a species listed as vulnerable, have been flown to Queensland after the rescue centre they were recovering in was at risk from fire and evacuated. Some of the orphans are now being cared for by the team at the hospital until they’re big enough to go home, and there’s no threat of fire. 🦇 In September, flying fox admissions to the hospital skyrocketed by over 750% due to drought conditions and lack of food. Flying foxes are now being drastically affected by wildfires and we’re again seeing an influx of these beautiful animals from across the country. This week, we treated our 90,000th patient. To cope with so many animals being admitted to the hospital, in 2019 we opened a sea turtle rehabilitation centre, sea snake ward and are about to complete a new bird recovery area, but it’s still not enough to keep up. We need to build a new ward for our patients. Wildlife Warriors from around the world are asking how they can help us save native wildlife, you can donate on our website , or support our fundraiser to start construction of our newest ward by visiting the link in my bio! 💚

Many Australian celebrities are now committed to benefit campaigns because of the fires. Actress Nicole Kidman donated $ 500,000 and called on others to do the same. Singer Pink donated the same amount, and rapper Iggy Azalea, born in Sydney, also called on to give generously with a picture of a rescued koala.

A collection by Australian comedian Celeste Barber, who has family in the affected area, was also widely shared. Almost three million euros were raised in three days for emergency aid.

Earlier this week, tennis star Nick Kyrgios had promised to donate 125 euros for every ace he hit at the ATP Cup, which had to move to Victoria due to the smoke in Sydney. The promise has already cost him around 2500 euros.

“It’s hard,” said the Australian emotionally after his first game. “At every store I could only think of that. It is difficult to concentrate on tennis then.” He said he was happy to be able to donate this money to firefighters, victims and conservationists.

Other players gave their own spin to Kyrgios’ initiative. Simona Halep, not known for her aces, promised to donate to every time she gave her coach a hard time played on the track, “this way the amount goes up faster”. The Australian Ashleigh Barty even promised to donate her entire prize money from the Brisbane tennis tournament that starts tomorrow.

In total, an area slightly larger than the Netherlands has gone up in flames. Australian Prime Minister Morrison, criticized for his lack of urgency, has called on 3,000 military reservists to help fight the fires. …

The effects of the fires are also noticeable in New Zealand, about 2,000 kilometers away: the smoke turns the sky orange there.

Koala drinks Australian cyclist’s water

Koala approaches cyclist for drink from water bottle in Australia

Dec. 27 (UPI) — A cyclist in Australia stopped to give a drink from her water bottle to a thirsty koala that approached her bicycle in the road.

Anna Heusler said she and some friends were cycling in the hills near Adelaide, South Australia, when they encountered a koala in the road.

“We were descending from Norton Summit Road back into the city early this morning and we came around a bend and there was a koala sitting in the middle of the road,” Heusler told 7News. “Naturally, we stopped because we were going to help relocate him off the road.”

A video posted to Instagram shows the koala accepting a drink from her water bottle and climbing onto her bicycle.

“I stopped on my bike and he walked right up to me, quite quickly for a koala, and as I was giving him a drink from all our water bottles, he actually climbed up onto my bike,” she said. “None of us have ever seen anything like it.”

She said the koala was escorted back to the woods at the side of the road.

Translated from Dutch NOS TV today:

Because of the ongoing fires and heat, koalas are having a hard time and thousands have recently died. That estimate was made by Australian Environment Minister Ley yesterday.

The minister thinks that possibly 30 percent of all koalas in the affected region have died, “because about 30 percent of their environment has been destroyed”. It would then be about 8000 dead koalas. …

In the coming days, another heatwave is expected in the eastern part of Australia, which has been dealing with catastrophic forest fires for weeks. In total there are around two hundred fires, of which more than half in the state of New South Wales.

Hundreds of homes have been destroyed and so far the forest fires have cost the lives of eleven people.

Trump-Russia escalation stops Australia bombing Syria

Question Time – Australia’s involvement in Iraq and Syria

Australia suspends air operations in Syria

Today, 08:48

Australia is stopping temporarily bombing Syria. According to the Australian Department of Defense, it is a precautionary measure, as the tensions between Russia and the United States over the air strikes have risen.

The reason for the tension is an incident in which US pilots shot a Syrian fighter plane down on Sunday. Russia, ally of Syria, is furious about that. Yesterday, Moscow announced that it is now considering all aircraft and drones of the international [Donald Trump’s Pentagon-led] coalition operating west of the Euphrates river as targets.

Also Australia has been a part of the international coalition that has been active over Syria for several years, but the country has now suspended that. The department does not yet say how for long the suspension will last.

The Australian participation in operations on Iraq will continue, says the ministry.

Raising the specter of the Syrian conflict escalating into a military confrontation between the world’s two major nuclear powers, the Russian Defense Ministry Monday issued a warning that it would treat any US or allied aircraft operating in western Syria, where Moscow’s own forces, as well as those of the Syrian government, are based, as a hostile target: here.
