#ecology and conservation

I'm livid. Attenborough played a large part in me deciding to follow ecology and conservation as a career path! The episode that's being withdrawn is about the destruction and rewilding of British natural habitats, which the general public need to see! Pandering to right-wing morons, who do nothing but bury their heads in the sand and pretend that they've got nothing to do with it, is not how we're going to fix it! The world is suffering biodiversity loss on a huge scale and more awareness means more likelihood of people coming together to find solutions! I've never been so disappointed with the BBC...

Most sharks are just big ocean puppies! I've always thought it was a little unfair how other apex predators like lions, wolves, and eagles are viewed as noble, powerful, beautiful, and majestic. But sharks are still far too often considered thoughtless killers (dead shark eyes), targeted man eaters (jaws did a lot for this continued misconception), and just largely scary.

Realistically sharks are just filling in the same ecological niche as those apex predators, except they're in the ocean. They're really no more dangerous than those other idolised predators, and they deserve the same grave and wonderment.

Just as we've seen people treat wolves, lions, ect with love and care in sanctuaries, there are people who lead dives to interact with friendly, habituated sharks. They've really been helping too de-villainise sharks, but it would be great to see more softness for them in the media.

When I was in vet school I went to this one lecture that I will never forget. Various clubs would have different guest lecturers come in to talk about relevant topics and since I was in the Wildlife Disease Association club I naturally attended all the wildlife and conservation discussions. Well on this particular occasion, the speakers started off telling us they had been working on a project involving the conservation of lemurs in Madagascar. Lemurs exist only in Madagascar, and they are in real trouble; they’re considered the most endangered group of mammals on Earth. This team of veterinarians was initially assembled to address threats to lemur health and work on conservation solutions to try and save as many lemur species from extinction as possible. As they explored the most present dangers to lemurs they found that although habitat loss was the primary problem for these vulnerable animals, predation by humans was a significant cause of losses as well. The vets realized it was crucial for the hunting of lemurs by native people to stop, but of course this is not so simple a problem.

The local Malagasy people are dealing with extreme poverty and food insecurity, with nearly half of children under five years old suffering from chronic malnutrition. The local people have always subsisted on hunting wildlife for food, and as Madagascar’s wildlife population declines, the people who rely on so-called bushmeat to survive are struggling more and more. People are literally starving.

Our conservation team thought about this a lot. They had initially intended to focus efforts on education but came to understand that this is not an issue arising from a lack of knowledge. For these people it is a question of survival. It doesn’t matter how many times a foreigner tells you not to eat an animal you’ve hunted your entire life, if your child is starving you are going to do everything in your power to keep your family alive.

So the vets changed course. Rather than focus efforts on simply teaching people about lemurs, they decided to try and use veterinary medicine to reduce the underlying issue of food insecurity. They supposed that if a reliable protein source could be introduced for the people who needed it, the dependence on meat from wildlife would greatly decrease. So they got to work establishing new flocks of chickens in the most at-risk communities, and also initiated an aggressive vaccination program for Newcastle disease (an infectious illness of poultry that is of particular concern in this area). They worked with over 600 households to ensure appropriate husbandry and vaccination for every flock, and soon found these communities were being transformed by the introduction of a steady protein source. Families with a healthy flock of chickens were far less likely to hunt wild animals like lemurs, and fewer kids went hungry. Thats what we call a win-win situation.

This chicken vaccine program became just one small part of an amazing conservation outreach initiative in Madagascar that puts local people at the center of everything they do. Helping these vulnerable communities of people helps similarly vulnerable wildlife, always. If we go into a country guns-blazing with that fire for conservation in our hearts and a plan to save native animals, we simply cannot ignore the humans who live around them. Doing so is counterintuitive to creating an effective plan because whether we recognize it or not, humans and animals are inextricably linked in many ways. A true conservation success story is one that doesn’t leave needy humans in its wake, and that is why I think this particular story has stuck with me for so long.

If you aren't following the news here in the Pacific Northwest, this is a very, very big deal. Our native salmon numbers have been plummeting over the past century and change. First it was due to overfishing by commercial canneries, then the dams went in and slowed the rivers down and blocked the salmons' migratory paths. More recently climate change is warming the water even more than the slower river flows have, and salmon can easily die of overheating in temperatures we would consider comfortable.

Removing the dams will allow the Klamath River and its tributaries to return to their natural states, making them more hospitable to salmon and other native wildlife (the reservoirs created by the dams were full of non-native fish stocked there over the years.) Not only will this help the salmon thrive, but it makes the entire ecosystem in the region more resilient. The nutrients that salmon bring back from their years in the ocean, stored within their flesh and bones, works its way through the surrounding forest and can be traced in plants several miles from the river.

This is also a victory for the Yurok, Karuk, and other indigenous people who have relied on the Klamath for many generations. The salmon aren't just a crucial source of food, but also deeply ingrained in indigenous cultures. It's a small step toward righting one of the many wrongs that indigenous people in the Americas have suffered for centuries.

I attended my first in-person conference on Tuesday, the British Ecological Society Aquatic Group annual meeting at Lancaster University! It was quite a small conference, but really enjoyable! So many incredibly interesting talks, ranging from global warming and ocean acidification to using meeting sponges to assess community diversity through eDNA!

Despite the grey, drizzly weather, it was a great experience, and I definitely have a few more papers to read and connections to make!

Lancaster uni also had a lovely campus with pretty architecture and lots of little green spaces! There was a gorgeous coffee shop on campus (who do amazing vegan hot chocolate!) called Coastal and co. If you're ever on campus, I highly recommend them! :)

Please enjoy this little photo I took outside of where the conference was! You can just about see the coffee shop I mentioned in the back!

I really, desperately want this to be our future. A lot of my work revolves around climate change. I have to look at current trends, and I have to consider worst-case-scenarios. And those are terrifying, and they need to be stopped at all costs.

But! I also look at what best case scenarios might be. And that gives me hope. If we can spread info about those true scary tend lines , but show those better case scenarios; maybe we can give people some hope and encouragement to make sustainable changes, and demand changes from governments, MPs, and big businesses.

I think we can make this future the reality we experience, I just think it will need a *lot* of effort, and a lot of working together as a community to put pressure on the big polluters.

In the future, children will think our ways are strange. "Why do old people always grow so much milkweed in their gardens?" they'll say. "Why do old people always write down when the first bees and butterflies show up? Why do old people hate lawn grass so much? Why do old people like to sit outside and watch bees?"

We will try to explain to them that when we were young, most people's yards were almost entirely short grass with barely any flowers at all, and it was so commonplace to spray poisons to kill insects and weeds that it was feared monarch butterflies and American bumblebees would soon go extinct. We will show them pictures of sidewalks, shops, and houses surrounded by empty grass without any flowers or vegetables and they will stare at them like we stared at pictures of grimy children working in coal mines

A sponge city is a new urban construction model for flood management, strengthening ecological infrastructure and drainage systems, proposed by Chinese researchers in early 2000 and accepted by the Chinese Communist Party (CCP) and the State Council as urbanism policy in 2014. It can alleviate urban flooding, water resources shortage, and the urban heat island effect and improve the ecological environment and biodiversity by absorbing and capturing rain water and utilizing it to reduce floods. (x)

Sponge cities are part of a worldwide movement that goes by various names: green infrastructure in Europe, low-impact development in the United States, water-sensitive urban design in Australia, natural infrastructure in Peru, nature-based solutions in Canada. In contrast to industrial management, in which people confine water with levees, channels, and asphalt and rush it off the land as quickly as possible, these newer approaches seek to restore water’s natural tendency to linger in places like wetlands and floodplains. — The architect making friends with flooding

This is so important, and I think more people should hear it. I'm also a PhD student, and my project involves looking at the impacts of climate change on marine ecology.

It's so infuriating seeing so many climate deniers talk about "conspiracies" and "woke propaganda" when they haven't done the first but if research or applied critical thinking to legitimately back up any of their claims.

Because, I've seen the reports, I've seen the studies, and I've seen scientists desperately try to reason with governments and businesses to reduce their carbon emissions, to reduce waste, and use clean energy. Because we know what's next if positive changes aren't made.

There's so so much historical climate data showing trend lines that are telling us that, where we're currently heading, is the path to irreversible global warming, biodiversity loss, and mass extinction.

Please listen to us when we say that climate change is real, it is happening right now, and we can fix it if we're quick.

"England is celebrating the first pair of beaver kits born in the country since they were reintroduced back into the country’s north last year.

Landscape managers in England are beside themselves with surprise over the changes brought about by a single year of beaver residency at the Wallington Estate in Northumberland—with dams, mudflats, and ponds just appearing out of nowhere across the landscape.

Released into a 25-acre habitat on the estate last year, the four beavers at Wallington are part of a series of beaver returns that took place across the UK starting in 2021 in Dorset. Last year, GNN reported that Hasel and Chompy were released into the 925-acre Ewhurst Estate in Hampshire in January 2023, and the beavers that have now reproduced established their home in Wallington in July.

“Beavers are changing the landscape all the time, you don’t really know what is coming next and that probably freaks some people out,” said Paul Hewitt, the countryside manager for the trust at Wallington. “They are basically river anarchists.”

“This time last year I don’t think I fully knew what beavers did. Now I understand a lot more and it is a massive lightbulb moment. It is such a magical animal in terms of what it does.”

It’s believed that the only animal which alters the natural environment to the same extent as humans is the beaver. Their constant felling of trees to construct dams causes creeks to build up into pools that spill out during rainfall across the land, cutting numerous other small channels into the soil that distribute water in multiple directions.

Hewitt says that in Wallington this has translated to a frantic return of glorious wildlife like kingfishers, herons, and bats.

Recently the mature pair of beavers mated and produced a kit, though its sex is not yet known because beavers don’t have external genitalia.

These beaver reintroductions have led to a raft of beaver sightings around the country. Those at the National Trust working to rewild the beaver back into Great Britain hope the recovery of the landscape will convince authorities to permit further reintroductions to bigger areas."

Five years after a massive effort to remove invasive mice and rats from Lord Howe Island, the unique ecosystem is experiencing what is being called "an ecological renaissance" as the endangered flora and fauna recovers.

Lord Howe Island woodhens were reduced to only 30 individuals in the 70s due to egg predation from the invasive rodents, but in just the last five years the population has jumped from 200 to over 2,000.

From the article:

"It's just amazing, the changes that have happened in the forest--it has blown me out of the water really. I thought it would change but I just can't believe how quickly things have been happening."
