A Burmese python and a bobcat facing off in the Big Cypress National Preserve in Florida last June, captured by a trap camera set up by the U.S. Geological Survey. U.S.G.S.
We have been posting about invasive pythons, as well as plenty of other invasive species, annually for more than a decade now. Likewise, feline wildlife has been a recurring theme. Not to mention camera traps, another theme we care about.
For a surprising overlap of those two themes, or otherwise just a very well-written story about wildlife, read Matt Kaplan’s article about how Bobcats With a Taste for Python Eggs Might Be the Guardians of Florida’s Swamp.

Our congratulations to Dr. Andrea Currylow for the determined pursuit leading this scientific finding, and with no disrespect to pythons as a species in their native territories, in this case may the best cat win:
Cameras captured the wild feline purloining a Burmese python’s eggs, giving hope that the state’s native species are responding to a voracious, invasive predator.
The bobcat took a swipe. U.S.G.S.
The voracious appetite of the invasive Burmese python is causing Florida’s mammal and bird populations to plummet. With little natural competition to control the big snake’s numbers, the situation looks desperate. But new observations suggest that the bobcat, a wildcat native to Florida, might be able to help.

If you do not eat animal protein, this concept may not appeal to you. But if you allow that others who eat meat may be able to do so ethically, then read on.
If you do eat any kind of meat, then it is a reasonable question whether invasive species are fair game: Rack of squirrel, anyone? The chefs putting invasive species on the menu

‘Invasivorism’ is a growing ethical dining trend but is ‘eat them to beat them’ really the answer?
From oral contraceptives to proposals to edit their DNA, efforts to control the UK’s invasive grey squirrel population have become increasingly elaborate. But a growing number of chefs and conservationists have a far simpler idea, which they see as part of the trend in ethical dining: eat them. Continue reading
Hundreds of frigate birds and boobies fly over a Crazy Ant Strike Team crew of volunteers at Johnston Atoll NWR.
In common language, they are called crazy. They terrorize birds on an island where they did not belong. On this platform we are always going to side with the birds. Full stop. But, even these lousy things ants do are impressive. They remind us that one day ants will rule the planet.
The yellow crazy ant was last spotted by Crazy Ant Strike Teams on the vital seabird nesting grounds in December 2017, but it was too soon to tell if they’d been fully extinguished because their colonies are found underground. Robert Peck/HCSU/USGS
After more than a decade, the terrorizing reign of the yellow crazy ant is over on the Johnston Atoll National Wildlife Refuge, part of the Pacific Remote Islands Marine National Monument.
The nonnative invasive insect had been threatening ground-nesting seabirds on the atoll since at least 2010, nearly wiping out the island’s red-tailed tropicbird colony in just a few years and wreaking havoc on other seabirds. But the U.S. Fish and Wildlife Service announced Wednesday that its campaign to eradicate the insects has been a success. Continue reading

We respect all things natural, but we acknowledge there are phenomena that test our principles. Historic swarms of locusts, for example, make us believe that getting control over their impact is essential for communities where they can lay waste to human endeavor, so we thank Rachel Nuwer for this story from one of the hardest-hit regions:

UNDER A WHITE SKY
The Nature of the Future
By Elizabeth Kolbert
A few years ago YouTube recommended I watch a video with the word “carpocalypse” in its title. I clicked the link — of course I did — and stared in awe at what resembled a mash-up of a video game, nature documentary and war movie. I saw a river full of fish leaping from the water like chaotic piscine fireworks and men in speedboats yelling and holding out nets to catch them as if they were wet and weighty butterflies. Fish hitting people in the face, fish landing in boats, fish flapping between people’s feet in a mess of slime and blood. Continue reading
In a brief interview a student recorded my description of the work I was doing in southern Chile from 2008-2010. The Patagonia Expedition Race had secured Wenger’s sponsorship, and now graduate students from Columbia Business School, as well as from Cornell Hotel School, were developing a strategy for how best to use that sponsorship money to achieve lasting conservation results. The patch on the left arm of my jacket shows another sponsor.
Organikos was a minor sponsor compared to Wenger, but in that earlier iteration of Organikos we were already thinking about what is now the 100% Forward commitment. As a sponsor, I also served coffee from sunrise to sunset at each station along the Race’s 500-mile route. Somewhere I have photos of the race teams drinking Organikos coffee, but at the moment I only find this one of me prepping coffee in the traditional Costa Rican manner to serve to Race volunteers in a farmhouse where we had spent the night on Tierra del Fuego.
In this photo to the left I was waiting for the racers who would soon be arriving at this station in their kayaks. As serious as I appeared to be, it would take nearly a decade to get that coffee launched more formally into the market.

Not long after the photos above were taken, we accepted a new assignment in India that would put the original idea of Organikos on hold. Recently, when Seth took the name and gave it a clear conservation mission, coffee was still the most viable product to start with. I am reminded of all that thanks to Sandra Laville, and the Guardian. Her article, full of good news related to conservation funding in the UK, triggers my memory of the fact that beavers are an invasive species in Patagonia and the Race had the mission of controlling their spread, in the interest of wilderness conservation. Beavers in their natural habitat are in need of protection in some locations, I see:

Philanthropic donations to environmental causes have more than doubled in value in the UK as the climate crisis and unprecedented biodiversity loss attract increasing attention from individuals and charities.
The amounts of money given to support efforts to tackle climate change and nature loss range from £5,000 to millions of pounds, and the focus of the funding is as broad.
It includes a £10,000 donation given to support a successful campaign for a deposit return scheme in Scotland; the funding of grassroots defenders of Europe’s last primeval forest, in Poland, and the protection of wetlands in Montenegro; and millions of pounds in support of environmental legal challenges and donations to back campaigning against fossil fuels.

Invasive species sometimes lead to creative opportunities, but rarely without some tradeoffs:
ENZO PÉRÈS-LABOURDETTE / YALE E360
As the curvy berm we started forming earlier this year, combined with 100+ newly planted trees, transition from wet season to dry season, we have been noticing an uptick in insects. While most of my early life experiences in Connecticut led me to believe that the world (or at least I) would be better off with fewer insects, I now think exactly the opposite. Last Sunday I had my first sighting of a bird (same species as our friend Daniel captured by camera in Guatemala a few weeks ago) that is likely here for some of those insects. That sighting alone would have been enough to convince me that more insects are better than fewer. Janet Marinelli‘s article in Yale Environment360 gives me more to ponder on this topic:
The impact of introduced plants on native biodiversity has emerged as a hot-button issue in ecology. But recent research provides new evidence that the displacement of native plant communities is a key cause of a collapse in insect populations and is affecting birds as well.
Zebra swallowtails are entirely dependent on pawpaw trees, which have leaves that are the butterflies’ larvae only source of food. COURTESY OF DOUGLAS TALLAMY
For years, Doug Tallamy sounded the alarm about the grave threat that plants introduced from abroad pose to native insects. By transforming native plant communities into so-called novel landscapes increasingly dominated by exotic species on which many insects cannot feed, the University of Delaware entomologist speculated, they imperil not only insects but also the birds and other animals that depend on insects for survival.

Urban beekeeping has exploded in Paris, and the honeybees have become an easy target for invasive wasps.
We recently published some good news about a similar invasive insect in Washington State, but it’s important to note that the species on the prowl in Paris is related, but not the same. Although far less dangerous (tell that to the honeybee prey…) they still are a menace to other insects, especially honeybees. The good news here is that the hornets have been in France for well over a decade, and the human wasp controllers have the skills and tools to combat them, protecting the thriving businesses of urban apiculture.
And other tales of hives and honeybees in the City of Light.
“The queen is dead?” a preschool administrator in suburban Paris asked Matthieu Bize, a wasp controller who had come to rid the schoolyard of Asian hornets.
On the ground, a nest was in tatters. Twenty minutes earlier, it had been high up in an ivy-choked tree, where it looked like a jumbo gray-brown balloon. Mr. Bize, 32, had sent a telescopic pole through the canopy, injected a paralyzing white powder into the hornets’ home, and knocked it down. The colony’s larvae, future queens among them, were strewn about. “Nearly finished here,” he said.
In English, the Bize family name is pronounced “bees”; in French, it is “bise” (short for kisses). Dozens of times a day, when Mr. Bize answers his cellphone — “C’est Monsieur Bize” — this gentle phrasing sweetens an otherwise sting-y situation.
For Mr. Bize doesn’t hunt just any pest. One-third of the nests to which he responds belong to a species of dreaded “murder hornet,” a type of wasp that beheads and feeds to its larvae an insect that is very important to, and symbolic of, France: the honeybee.
Beyond the fact that Napoleon chose the honeybee for his logo in the early 19th century (the emperor favored the insect for its tenacity), France is the European Union’s largest agricultural producer, and generally known for pollinator-friendly policies. It is also one of Europe’s major honey trade hubs.

If you noted the danger five months ago, and find this topic newsworthy, you know how important it was to find the nest. Finally, after an exhaustive search, they found it and it seems we should count this as good news, especially in a year like 2020:
Officials said they planned to destroy the nest in Blaine, Wash., on Saturday before the voracious Asian giant hornets could multiply and lay waste to bees.
Like detectives closing in on a fugitive hide-out deep in the woods, officials in Washington State announced on Friday that they had located the first murder hornet nest in the United States, tucked in a tree hollow near the Canadian border.
The officials said they planned to destroy the nest in Blaine, Wash., on Saturday before the voracious Asian giant hornets could multiply and begin laying waste to bees that are vital to the survival of the region’s raspberries, blueberries and other crops. Continue reading

When we first linked to a story about this creature, we were sharing a familiar story of introduced and invasive species and a creative approach to controlling the spread. We have favored entrepreneurial approaches, so that culinary story from Japan fit perfectly in our pages. But we also have been equally attentive to word matters since we started on this platform. So Matthew Alt’s coverage of this story, demonstrating how much words matter, also fits perfectly in our pages:

For every invasion there is an appropriate response, and sometimes it is culinary. Thanks to Ben Dooley for this set of ideas:
Long before the insects found their way to American shores, some Japanese prized them for their numbing crunch and the venomous buzz they add to liquor.
TOKYO — Long before the Asian giant hornet began terrorizing the honeybees of Washington State, the ferocious insects posed a sometimes lethal threat to hikers and farmers in the mountains of rural Japan.
But in the central Chubu region, these insects — sometimes called “murder hornets” — are known for more than their aggression and excruciating sting. They are seen as a pleasant snack and an invigorating ingredient in drinks.
The giant hornet, along with other varieties of wasps, has traditionally been considered a delicacy in this rugged part of the country. The grubs are often preserved in jars, pan-fried or steamed with rice to make a savory dish called hebo-gohan. The adults, which can be two inches long, are fried on skewers, stinger and all, until the carapace becomes light and crunchy. They leave a warming, tingling sensation when eaten. Continue reading

We first started paying attention to invasive species here. Since then, every year, we pay more and more attention, especially to the pythons in the Everglades. It is that time of year:
Since we started this platform in 2011 I have been on the lookout for graphical representations that help me, and therefore might help others, understand complex issues related to the environment. Photography has been the easiest reach for me, perhaps because I am a son of, a brother of, and a father of people who have mastered that form. Comics were not part of my life, so that form has eluded me. And I realize that the work of Susie Cagle escaped my attention–as I have shared visual artists’ depictions of natural phenomena, with science and especially ecological issues emphasized–until now. And this is a good way for her work to come to my attention, because in our family we have been debating this tree’s value for decades:

With invasive species, sometimes the only thing to do with such lemons is make them tasty:

Tens of millions of voracious purple sea urchins that have already chomped their way through towering underwater kelp forests in California are spreading north to Oregon, sending the delicate marine ecosystem off the shore into such disarray that other critical species are starving to death.
A recent count found 350m purple sea urchins on one Oregon reef alone – more than a 10,000% increase since 2014. And in northern California, 90% of the giant bull kelp forests have been devoured by the urchins, perhaps never to return.
Vast “urchin barrens” – stretches of denuded seafloor dotted with nothing but hundreds of the spiny orbs – have spread to coastal Oregon, where kelp forests were once so thick it was impossible to navigate some areas by boat. Continue reading

There are tens of thousands of pythons in the Florida wild, attacking animals and damaging ecosystems – and the quest to stop them has become a collective crusade

On a Thursday afternoon in St Petersburg, Florida, Beth Koehler crouches over a cairn terrier named Ginger, trimming intently as fur collects around her feet. On Koehler’s arm is a scratch – red, jagged and freshly acquired, though not in the way one might expect of a dog groomer.
“There was no way I could pin the head,” Koehler says, referring to the snake that was partly responsible. She had grabbed hold however she could, which made it “pissed”: “It decided to coil up and just throw itself at me.” Startled, Koehler had fallen backwards, cutting herself on a vine – an injury far preferable to the bite of a Burmese python.
“I have never been bit,” she proudly adds. “Peggy’s been bit once, but really, we’re very careful.”
Three days a week, Koehler runs Hair of the Dog with her partner of 31 years, Peggy van Gorder. The other four days the couple are usually out chasing pythons as members of Patric: the Python Action Team – Removing Invasive Constrictors, which is managed by the Florida fish and wildlife conservation commission (FWC).

After writing about some of Cyprus’ environmentally destructive actions, it feels good to hear about these positive organized efforts to eradicate this marine threat. Lionfish have long been on our radar, but this is the first we’ve heard of their spread through European waters.
Perhaps a new venue for eradication idea exchange is in order!
Cyprus has held its first organised cull of lionfish after numbers of the invasive species have proliferated in recent years, threatening the Mediterranean ecosystem and posing a venomous danger to humans.
“They’re actually very placid,” said Prof Jason Hall-Spencer, a marine biologist, after spearing 16 of the exotic specimens in the space of 40 minutes in the inaugural “lionfish removal derby” off the island’s southern coast. He added: “The problem is they are not part of the natural ecosystem and we are seeing them in plague proportions.”
Lionfish, armed with venomous dorsal spines that enable them to deter predators, are more normally associated with warm tropical waters of the South Pacific and Indian Ocean. Almost two decades ago the non-native tropical fish began to enter US waters, appearing in the Atlantic after pet owners started releasing outsized lionfish from home aquariums into the sea. Now they have reached Europe. In 2012, after initial sightings off Turkey, Israel and Lebanon, they were spotted off Cyprus. Three years later they had appeared further south in Greece, Italy and Tunisia, testimony, scientists say, to their ability to both enter new territories and spawn at record rates.
As numbers proliferate, so have fears of the flamboyantly coloured fish posing the biggest ecological setback to ecosystems in the Mediterranean – which is already under pressure from pollution, tourism and over-exploitation. In the EU, Cyprus has become “the first line of defence” against the lionfish invasion. Continue reading
Elephants have held highest honors in our family for decades, as symbols for the importance of Nature Conservation, and later infused with the power of Ganesh when we lived in India.
Elephant conservation has taken many forms over the years. When writing about the recent Real Elephant Collective collaboration exhibit that took place in Cochin a few months ago, I realized that art installations using elephants as symbols for big picture conservation have existed for some time.
Having been unable to attend the exhibit personally, Anoodha and the Curiouser team make me feel that I was there.
We missed the story last year about two men in the photo above, from southern India, who were brought to the Florida habitat where invasive pythons are doing enough damage that we started paying attention eight years ago. We are thinking about it again, thanks to the Guardian:
Snake hunters have captured what they say is the largest python ever found in the swamps of the Florida Everglades: a pregnant female more than 17ft (5.2 metres) long and weighing 140lb, or 63.5kg.
The team from the Big Cypress National Preserve posted news of their record-setting catch in a Facebook post that also noted the giant reptile was carrying 73 eggs.

Environmentalists have been struggling to find ways to eradicate Burmese pythons, a non-native species, from the 1.5m-acre wilderness since the 1980s, when some were released into the wild as overgrown pets. Others escaped from a breeding facility wrecked by Hurricane Andrew in 1992. Continue reading
