A beaver colony in the Brdy region has gained overnight fame by building several dams in the Brdy protected landscape area, creating a natural wetland exactly where it was needed. It saved the local authorities 30 million crowns, and has the public cracking jokes about public administration and red tape.

The administration of the Brdy protected landscape area, which had gained approval for the 30 million crown project, was dealing with red tape and seeking the respective building permits from the Vltava River Basin authorities when the dam project was completed almost overnight by a local colony of beavers.

They could not have chosen their location better –erecting the dams on a bypass gully that was built by soldiers in the former military base years ago, so as to drain the area. The revitalization project drafted by environmentalists was supposed to remedy this. Bohumil Fišer, head of the Brdy Protected Landscape Area Administration says Nature took its course and the beavers created the necessary biotope conditions practically overnight.

Excess Nitrates in Groundwater - Effects and Current Situation in India

Introduction Groundwater contamination due to excess nitrates is a pressing issue in India, affecting drinking water safety and public health. Nitrate pollution arises mainly from agricultural runoff, improper waste disposal, and industrial activities. However, nitrates are not the only harmful chemicals contaminating groundwater. Other dangerous substances such as arsenic, fluoride, and heavy…

Following an accident, Danny wakes up in Gotham City in a DC universe. Lacking any forms of ID or possessions beyond the clothes on his back, he’s forced to commit some crimes to survive. Minor crimes, but still.

And then he gets caught.

During the court proceedings, they come to the mistaken conclusion that he’s a Meta suffering from some psychiatric issues such as Cotard’s Syndrome (a real rare condition where a person holds the delusional belief that they’re dead/don’t exist/etc).

Thus, between his “need for mental treatment” and the concerns about housing someone with his unique physical traits, he is sentenced to spend time in Arkham Asylum. He’s under pretty low security aside from the anti-Meta stuff and has more freedoms than some other inmates, but it’s still not a great experience. Even at the best of times, Arkham is hardly a nice place.

Some of his fellow residents are decently chill all things considered, but lots very much aren’t.

So. I'm an Environmental Engineering searching for a entry level / early career job remote or if with the opportunity of sponsorship to move to another country. So don't doubt if you need me. I'm really commitment with the cause, and working in a place that give me the opportunity to learn and grow professionally and academically that would be great. And all that while we protect the environment of course.

Stop the Army Corps from Draining Thousands of Acres of Wetlands

Yet again, the U.S. Army Corps of Engineers has resurrected a destructive project in Mississippi's South Delta that would damage at least 90,000 acres of wetlands that support more than 450 species of birds and wildlife. Their “preferred alternative” for the Yazoo Backwater Area Water Management Project is slated to include a massive pump that will drain and damage hemispherically important wetlands.

Urge the Army Corps to abandon this project once and for all. The deadline to comment is August 27.

Note: Your letter will be sent directly to the U.S. Army Corps of Engineers as part of a public comment period and will become part of the public record.

Two Peas in a Pod: part 2/?

*slips another piece into your mailbox*

_____________________

Jazz was still feeling a little woozy from his donation in the dark hours of the morning. Blaster had breakfast changed from the usual to something that felt more like a treat, probably a reward for his good behaviour, and to help his body recover. Fish heavy in proteins, fat, all that healthy stuff. Something that normally he would have tried to savour, but he wolfed it down from excitement. Too many questions ran through his head, and most he couldn't bring himself to voice.

The mer, the mer would pull through. Blaster told him about how he had saved their life with his blood. Praised him high and low. Because Blaster knew how Jazz felt about seeing blood, about how hard blood tests were for him, and that was only a tiny vial. Not three big bags of it. Jazz hadn't seen how much they had taken – because he had kept his eye closed until they left in a hurry –, and hearing about it made him dizzy for other reasons, but he honestly felt real proud of himself.

It was a new feeling, different from other moments of pride – like when he figured out the lock codes. Yeah, this gave him butterflies and the drive to help more.

Blaster laughed when Jazz offered that the vets could take more if the other mer needed it. His handler didn't think it would be, but he would pass it on to the vet team.

Jazz's morning checks were a little off, expected with having a little less fluids and feeling off-balance, but it was kept short and quick. Blaster told him that if he learned anything more, he'd tell him next time he came by and then hurried back down to the staff area. Blaster was needed elsewhere, understandably as there weren't many mer experts here, though he did leave Jazz his waterproof stereo if he wanted to play some of his favourites.

But, the orca mer was far too busy causing a whirlpool from the laps he was swimming. He was too excited to sit still, and embarrassment be damned he started practising old vocals. He didn't remember much of his mother tongue, and he was pretty sure that his pronunciation was off, that or had one hell of an accent. Echo-speech was even more rusty. And once he had gone over and over what he could recall, Jazz began to really worry. A few sentences and handful or so of words was all he had? Gods, I hope I can at least make a decent first impression. Blaster said they were just like me, so hopefully, that will give me some starting points.

More than he cared to count, Jazz would swim into the shallow waters of the medical bay and hope to see something through that window. But no one ever came close enough for him to hear any news of the mer. He couldn't even see anything on his radar, wherever they had done treatment, it wasn't in the hospital ward. It almost felt like he was being purposely kept in the dark.

And just when Jazz was starting to worry that things had taken a bad turn, a group of staff turned up around four pm. He wasn't able to ask any questions, or rather they refused to answer. Shooing him away as they got to work. Starting with closing the gate to the bay to 'keep him out'. Jazz could easily climb those walls, but that wasn't the point. Even if the gate window was closed, he could pick up that they were setting up the water hammock. But it wasn't until he heard the cautionary beeping of the hoist lift approaching that it dawned on him – the mer was coming. Now.

"Jazz," Blaster called, "… Jazz," he blew the training whistle and finally got his mer's attention. "Stop pacing and get over here."

"But–" Jazz looked back longingly up the wall.

"Jazz," his tone dropped to a firm one, and Jazz begrudgingly swam over to the pier. The human crouched and made sure that they held eye contact before he spoke. "I need you to promise me that you will stay in your enclosure."

He sunk a little, trying to play into his cuteness, but being far too anxious to really pull it off. "What do you mean?"

"Jazz," now warning him. Blaster knew full well that he was more than capable of getting into or out of places he shouldn't, bloody Houdini mermaid, "this is serious. Things are going well, we want to keep it that way. Which means keeping things calm and feeling safe. You're excited, I get it, we all are. But in about an hour, they'll be waking up and – from past experience seen with wild Mers – they will likely freak out. And the last thing we need is you hauling your tail over that wall and making things worse. Understand?"

The beeping was louder how and the hiss of hydraulics caused Jazz to look up. The arm of the lift was visible over the wall. They're here!

"Jazz," Blaster hopelessly called for his attention once more.

Within moments, a massive bundle was carefully raised, the staff calling out and coordinating. Jazz's gaze was fixed on the black and white fluke poking out, it was the only part of them he could see, and his heart began to race. Once they became hidden by the wall again, Jazz moved back to pacing by the gate without even thinking. Listening to people hopping into the water to unstrap the mer and call back n' forth. "Careful, careful! – Watch the head! – Someone give me a hand over here! – We're clear on this side! – Keep the head up!"

Really starting to sound like a broken record, Blaster chirped the whistle and called out to him again. The expression he wore must have been pretty pitiful because the look on Blaster's face dropped. "If I open the view port… will you promise me that you will wait, that you will stay in your enclosure?"

"I promise," he answered hastily, placing his hands on the gate, over the panel that would slide open.

"And that you will wait until everything is in the clear, till the staff come to oversee the integration. There will be no rushing things and no asking staff when we will open the gate."

"I promise," he repeated, trying not to beg.

Satisfied, Blaster pulled out his radio, "Blaster to Control; when the team is out of the Mer enclosure's medical bay, open the view port. Jazz's stress is mounting without a visual."

"Can do," came a quick reply.

Though, opening the panel was not. Several minutes went by, the hoist had cleared out, and much of the staff had returned to their other duties. Only two remained double-checking the mer's breathing and pulse. The moment that the last of them left, Jazz heard the lock disengage, and he retracted his hands as the panel shifted and began to slide open. The window was too small to get more than his hand – maybe up to his elbow if he wanted to push it – through, and sat just at water level– any movement sending water hopping to either side. But it gave him a clear view of the surface area inside.

Oh.

Oh. Jazz stopped breathing. While the mer's body was mostly supported by the fabric of the hammock, cradling them on their side, effectively hiding most of them from Jazz's angle. Propped up on a soft floating platform was the mer's head, face towards the gate. Sharp features and elegantly shaped finials, with flattering lines of their markings complimenting the peaceful expression as they slept. The butterflies from earlier came back stronger than ever, his heart thundering as words fumbled from Jazz's lips, "he's beautiful…"

Orca Prowl really is just-- too fucking pretty, omg, I'm living through Jazz in this moment like when I first saw your designs of him.

I'm more than happy to continue writing for you, you bring me so much joy. I screamed when I saw how much you liked it. If you have any requests you would like me to add to the story, leave it in the tags or comments ♡ I now plan to continue until the tsunami and a bit afterwards, maybe more, we'll see~

The way it all starts at night and then you (as a reader) have all this additional time to boil in your anticipation?? So fucking great. Like you can really feel how little power Jazz has over the wholse situation. The plot is moving but he doesn't have any saying in it. Well. Yet heheh

Anyway haha. Im normal and I made some art>:D

De-Extinction and Dire Wolves: Should We Clone Extinct Animals?

This article originally appeared on my website at https://rebeccalexa.com/de-extinction-and-dire-wolves-should-we-clone-extinct-animals/

My social media feeds this week have been full of headlines about how a trio of genetically engineered dire wolves are the newest advance in the quest to clone extinct animals. The short version is that researchers from Colossal Biosciences altered fourteen genes in the gray wolf (Canis lupus) genome to resemble genes taken from dire wolf (Aenocyon dirus) fossils. The DNA was then inserted into denucleated domestic dog (Canis familiaris) egg cells which were then implanted in domestic dog surrogates.

Romulus and Remus, two of Colossal Bioscience’s genetically engineered “dire” wolves.

Three of these eggs resulted in viable pups. Romulus and Remus are six months old, while Khaleesi is two months. The pups are white-furred, heavier-boned than gray wolves, and show wolf-like wariness of humans. But are they true dire wolves?

That’s the real question. You can add in genes from a dire wolf to an extant canid, but that doesn’t make them identical to the extinct species. Moreover, dire wolves are not as closely related to gray wolves as was previously thought; they were recently reassigned to a new genus that reflects their closer resemblance to modern-day jackals. There really isn’t a good analogue to them alive today, particularly when compared to the aurochs, another extinct species, and its domestic cattle descendants.

Is this really a good idea? Find out my thoughts on the matter under the cut!

There have been attempts to backbreed domestic cattle (Bos taurus) to aurochs (Bos primigenius), which went extinct a mere 400 years ago. Heck cattle and the Tauros programme are two examples of efforts to create cattle that more closely resemble their wild forebears. Aurochs backbreeding involves choosing animals that physically resemble the extinct animals, such as having longer faces and legs, curled horns, and dark coloration with a white muzzle. However, just as you can’t make a gray wolf by breeding wolf-like domestic dogs, you can’t make a true aurochs with domesticated cattle.

This gets us into phenotype (appearance and other physical characteristics) vs. genotype (genetic material). We don’t know exactly what dire wolves looked like, beyond their preserved bones, and possibly the genes that gave the three pups their thick, white pelage. We also don’t know how they behaved, and there are no living dire wolves to teach the pups the ways of their world. While we can make some educated guesses based on the behaviors of extant social canids like gray wolves and African painted dogs (Lycaon pictus), we can’t say with full certainty that dire wolves behaved the same way.

Let’s say we could clone extinct animals and somehow make a genotypically perfect dire wolf. The youngest reliably dated dire wolf remains are from about 10,000 years ago. This may seem like a relatively short time, and from a geological perspective it is. But a lot can happen in that time biologically and ecologically–for example, mule deer (Odocoileus hemionus) only appeared as a distinct species 10,000 years ago from hybridization of white-tailed deer (Odocoileus virginianus) and black-tailed deer (Odocoileus hemionus). And while human overhunting likely contributed to the extinction of many species of megafauna at the end of the last ice age 11,000-12,000 years ago, climate change was almost certainly a major factor as well. Given that the planet is heating up even more rapidly due to anthropogenic climate change, would it even be ethical to bring these cold-weather animals back under current conditions?

And, finally, would they still fulfill the same ecological role that they did thousands of years ago? Plains bison (Bison bison bison) and domestic cattle may be related, and share some behaviors, but cattle absolutely are not good replacements for bison. Their grazing patterns and migratory tendencies vary significantly, as does the makeup of their manure, all of which have impacts on local ecology. Some people argue that feral domestic horses (Equus caballus) belong in North America because they may fill a niche left when the last native North American horse, Equus occidentalis, went extinct along with other ice age megafauna. However, once again the landscape has changed significantly in 12,000 years, and niches have shifted in intervening millennia, and so domesticated horses are not the perfect replacement for their extinct counterparts.

This isn’t even getting into the ethics of bringing back an extinct species when there’s no place set for them in the wild. The debate over de-extinction overshadows the grim reality that we are still chewing up wild habitat at unprecedented rates, putting an increasing number of species at risk of extinction–or driving them entirely over the edge. It’s easier to get excited about sexy headlines featuring Jurassic Park-style wild science than the ongoing fight to not only put the brakes on environmental destruction–no small feat–but repair the damage.

All of which is to say while it’s interesting to see the genetic engineering advances represented by the three “dire wolves” now revealed to the world, it doesn’t mean that we’ve brought back an entire extinct species. And really, is the best tactic right now to clone extinct animals? While we could potentially use this technology to clone critically endangered species and reinject preserved DNA from long-dead individuals into the active gene pool, it’s very resource-intensive. And none of this is as important as preserving the habitats that these rare species need to survive. Eye-catching headlines about dire wolves may help raise awareness and funding, but they are not a replacement for the ongoing hard work of conservation.

Everything were fine and just for one f*cking comment, everything is a hell now.

European bison released in England’s ancient woodland have doubled in number since 2022, and the woodland has gotten healthier since, reviving previously extinct beetle species and increasing sightings of dormice and reptiles. And England isn’t the only European nation getting bison back in business: In the 1920s, there were just 54 European bison after intense hunting over millennia, but thanks to re-wilding efforts there are now around 10,000, mostly in Russia and Belarus.
