Elusive jaguar seen on trail camera in southern Arizona is 'good news,' experts say

Yahoo5 days ago
One of Arizona's most elusive sights showed up in a series of trail camera images collected by volunteer scientists in a Sky Islands mountain range near the U.S.-Mexico border: a jaguar roaming a remote landscape.
The image is the latest of five jaguar sightings documented this summer by the University of Arizona's Wild Cat Research and Conservation Center and their team of citizen scientists. Researchers said all of the images are of the same male jaguar, which was last seen in the same area over a year and a half ago.
'We're really excited that it's on the landscape again, because it speaks volumes about the biodiversity of the ecosystem,' said Susan Malusa, a biogeographer and co-coordinator for the researcher center. 'It's good news to see that an ecosystem is healthy for tiny little herbivores up to these apex predators.'
The University of Arizona's jaguar and ocelot monitoring program has been operating for almost 15 years, collecting over 200 detections (which include photo, video and DNA samples) of four jaguars documented in the region for scientific research. The program also contributes to the research of dozens of other species, including protected ocelots, gray wolves and golden eagles.
The camera traps are almost entirely maintained by citizen scientists, who are volunteers trained by the center.
'We really do want people to recognize the community-driven science here,' said Malusa, who has managed the project since 2011. 'This is a wonderful group of people, and their commitment has made this happen.'
Sky Islands: Where the border wall ends, wildlife survives. Advocates fear losses if the gaps close
Border wall, mining challenge jaguar recovery in Arizona
Jaguars are the largest cats in the Western Hemisphere, and are best characterized by their distinctive spots, known as rosettes, which form a unique pattern specific to each jaguar and help researchers identify individual jaguars from photos.
There have been eight jaguars photographed in the United States since 1996. The cats were listed as endangered under the Endangered Species Act in 1997.
The long-term datasets collected by the university's monitoring project help researchers understand the species' habitat range and contribute to the conservation and recovery of the binational population.
Primary threats to jaguars in the United States include habitat loss and fragmentation, which have been highlighted in recent years by controversial mining projects and border wall construction in southern Arizona.

In 2014, the U.S. Fish and Wildlife Service designated over 750,000 acres of critical habitat for the species along the border in southern Arizona and New Mexico, but that area was reduced by about 65,000 acres in 2024 after the 9th U.S. Circuit Court of Appeals, hearing a lawsuit filed by mining company Rosemont Copper, a subsidiary of the Canadian Hudbay Minerals, found the federal government didn't prove the acreage was essential to the species' survival.
In July, conservation groups sued the Trump administration over plans to construct a border wall across the San Rafael Valley, one of the last stretches of untouched borderlands where jaguars and ocelots have been documented crossing into the United States from Mexico.

Homeowner's camera captures rare footage of unexpected visitors playing in creek: 'For me, it was very exciting'

Homeowner's camera captures rare footage of unexpected visitors playing in creek: 'For me, it was very exciting' Habitat loss and trapping slashed the common river otter's population in the late 1800s, according to the Ohio Department of Natural Resources. The mammal was hunted to extremes during the Fur Trade Era (1600 to 1850) but was reintroduced in Ohio from 1986 to 1993. Because of this reintroduction, the presence of river otters has been confirmed in 86 of 88 Ohio counties as of 2020. As these animals thrive, biodiversity is reinstated in areas where the river otter once ruled. Oxford, Ohio, resident Jim Hermann captured images on his trail cameras of river otters playing on his property, per The Miami Student. Hermann told the newspaper: "For me, it was very exciting. … I wouldn't have expected them here." While Hermann set up his trail cameras to watch the beavers that were chewing on his trees, he was treated to a rare sight. Trail cameras are good for this. Researchers use them to watch animals in their natural habitats and track the populations of endangered species. For instance, Galápagos Conservancy uses trail cameras to classify native animals and track their behaviors and population changes. It then uses this data to determine what a species may need to be better served by conservationists. Of course, these devices are not just used by conservation organizations. Anyone can set them up to spy on animals at play with the added possibility of surprise appearances of rare critters. When these sightings are reported, as they are encouraged to be, officials can add data to their studies on animal population changes and track the results of rehabilitation efforts. Organizations such as Otter Watch and the River Otter Ecology Project ask people to report sightings of otters in nature. Hermann's sighting in a town not used to seeing river otters gives hope to biologists, conservationists, and animal lovers alike. Do you think America is in a housing crisis? Definitely Not sure No way Only in some cities Click your choice to see results and speak your mind. "We want to have a healthy population that can sustain itself and provide resources," Miami University student Aiden Schmeling said to The Miami Student. "They are a mid-upper level predator on fish and aquatic life, so that indicates there's adequate water quality for our fish. It tells us that we have a big enough ecosystem to support a predator." Hermann told the newspaper: "There are bright spots. One of those bright spots is the reappearance of these big mammal and bird species that have come back to Ohio."

These crabs probably saved your life. Can we save theirs?

BAY POINT, New Jersey — Susan Linder was hunting for buried treasure. Kneeling at low tide, the biologist dug up small shovelfuls of sand, scanning each scoop for tiny jewels. One yielded a cluster of jade-colored beads. Another, from a few feet away, contained a clutch the color of amethyst. They were eggs. In a few weeks, they would hatch into horseshoe crabs, one of the most ancient and important animals in the United States. The crabs in the Delaware Bay are the stars of an annual ecological opera involving sex, binge eating and literal bloodlust. Every spring, the crabs clickety-clack ashore along for a massive orgy timed to the rise and fall of the tides, depositing millions of eggs in the sand. 'They're easy to miss, really,' Linder said, digging the day after a New Moon, one of the biggest breeding days of the year. Her job is to help conduct an egg census. She returns all the clutches she finds carefully to the holes. She knows, year after year, the numbers have been diminishing. For decades, the biomedical industry has relied on a compound in horseshoe crab blood to protect medical equipment from contamination, saving untold human lives. The surge in vaccine use during the coronavirus pandemic, as well as the growing popularity of injectable weight loss and diabetes drugs, has further fueled the blood harvest. But conservationists say modern medicine's dependence on this bloodletting is upending a globe-spanning ecosystem in which birds bulk up on fatty crab eggs to fuel epic migrations. 'We're in this battle over horseshoe crab blood,' said Larry Niles, a wildlife biologist and co-founder of the Horseshoe Crab Recovery Coalition, a campaign trying to stop overharvesting. Now, finally, the crabs have a chance at a reprieve. A key group that sets standards for U.S. drugmakers has officially recognized a human-made alternative as safe and effective, opening the way for pharmaceutical companies to widely adopt alternatives and wean themselves off of crab blood. But only a handful of drugmakers have begun to adopt it. 'We're trying to encourage the pharmaceutical companies to switch to the synthetic,' Niles said, 'not only to help horseshoe crabs, but also for their own sake.' It might as well be an extraterrestrial. Its helmet-shaped body is covered with 10 eyes, some sensitive to ultraviolet light so it can follow the phases of the Moon and come ashore for a mating frenzy. Its mouth is on its underside and is surrounded by six pairs of legs it uses to test the water composition and to chew its food. When flipped belly-up on a beach, it uses its spear-like tail to pole-vault itself upright. But the crabs' claim to Earth predates pretty much everything else here. They are what scientists call a 'living fossil,' scuttling for hundreds of millions of years before the Atlantic Ocean was even a puddle. 'When you think about the genetic diversity and how long these guys have survived, they must be doing something right,' Amanda Dey, a retired zoologist who works with and is married to Niles. Perhaps the best adaptation accumulated over their 445 million years is their blood. It is a haunting blue hue due to copper-based molecules used to transport oxygen. It is also laced with immune cells called amoebocytes that coagulate around bacterial intruders. For a half-century, the biomedical industry has harvested an extract from these immune cells. Known as limulus amebocyte lysate, or LAL, it is used to test for the presence of bacterial contaminants called endotoxins, which could cause a patient's organ failure and death. Regulators require tests for vaccines, pacemakers, heart stents, surgical tools and other medical devices, as well as water systems used in drug manufacturing. The blood-drawing process involves plucking horseshoe crabs from shores and transporting them miles to bleeding facilities. There, they are inspected, cleaned and bent on racks to expose a membrane for blood extraction. Afterward, they are released back into the water. Companies involved in this work say the crabs are handled with care, with a limited amount of blood taken only from healthy crabs that are subsequently returned to their native waters. 'Our processes are designed to preserve and protect horseshoe crabs,' said Nora Blair, a senior manager at Massachusetts-based Charles River Laboratories, a major lysate supplier for the pharmaceutical industry. The company has developed techniques for using crab blood more efficiently for testing, Blair added. As part of a lawsuit settlement with environmentalists in 2023, it also agreed to stop collecting crabs from certain beaches where birds feed and to stop placing female crabs in holding ponds so they can continue spawning. But conservationists say such measures aren't enough. About 15 percent of the crabs collected each year perish, according to the Atlantic States Marine Fisheries Commission. In 2023 alone, that portion amounted to 178,000 dead crabs. (The bleeding companies contest those figures.) The density of eggs laid on the Delaware Bay beaches has declined by 80 percent, from about 50,000 eggs per square meter in the early 1990s to around just 10,000 today, according to research from Niles, Dey and others. For years, the practice of using horseshoe crab flesh as bait for commercial fishing was responsible for much of the decline. But that practice has become more regulated — while the number of crabs collected for bleeding has swelled, increasing fourfold since 2004. Last year, environmentalists petitioned the federal government to add the American horseshoe crab to the Endangered Species Act list. A decision is pending. The International Union for Conservation of Nature, which also tracks the status of species, has already declared the American horseshoe crab 'vulnerable.' There used to be more than enough eggs to both perpetuate the horseshoe crab population and provide a fatty feast for hungry shorebirds, establishing this stretch of New Jersey as a key pit stop for ruddy turnstones, sanderlings, short-billed dowitchers, dunlins and other migratory birds. The red knot, in particular, needs the extra calories. It makes one of the longest annual journeys of any bird, flying more than 9,000 miles from the southern tip of South America to its breeding ground in the Arctic tundra — and back again. By the time some arrive in the United States, they will have flown six days without stopping. While Linder counted eggs on the beach, ornithologists Humphrey Sitters and Stephanie Feigin sat at the front of a boat cruising along the New Jersey side of Delaware Bay to tally every shorebird that they could spot. A plane buzzed above to count, as well. 'Dead ahead,' Sitters said, pointing across the bow to a flock of red knots on shore, as waves of semipalmated sandpipers darted across the surface of the water. '350 knots,' he announced. Feigin added the tally to her notebook. 'Semis?' she asked. 'Let's say 3,000,' he answered. Sitters said he knows from practice what a group of about 50 birds looks like and extrapolates that figure to the size of the flock in front of him. 'It's experience,' he said. 'Eventually, you get your eye' for it. There used to be many more knots to tally. The annual bird surveys show the decline in crab eggs has contributed to a staggering 70 percent drop in the average knot count from the early 1980s to 2014, when the U.S. Fish and Wildlife Service listed the bird as threatened under the Endangered Species Act. A quarter century ago, 'the Delaware Bay was one of the top birding destinations in the world,' Niles said as he piloted the boat. 'There were so many shorebirds in one place.' Without bulking up on eggs, knots take longer to reach their nesting grounds — and many don't make it at all, his research suggests. Now, four of the bay's most abundant shorebirds — red knots, ruddy turnstones, sanderlings and semipalmated sandpipers — are all in decline. 'The stopover is becoming unstable,' he said. 'One year is good, the next year is not. And it's all because the level and number of horseshoe crabs are so low.' In the late 1990s, researchers in Singapore patented a lab-made alternative to the lysate in horseshoe crabs' blood. But that breakthrough has yet to revolutionize drug-making industry. 'Pharma is just inherently conservative,' said Jay Bolden, a senior director at Eli Lilly. 'Why change the status quo when it's been working well for 40 years? But people don't see the impact outside of our own four walls.' In 2018, the U.S. Food and Drug Administration allowed Eli Lilly to use a synthetic for endotoxin testing for a migraine drug. As both a businessman and amateur birder, Bolden thought the move made sense. One bad year for the crabs, he thought, could stifle drug production if enough blood isn't harvested. 'If we're not reliant on a wild animal for one of our tests,' he said, 'then we're inherently in a better supply-chain position.' Crab advocates notched another victory when U.S. Pharmacopeia, a nonprofit that sets quality standards for drugs, issued guidelines deeming the synthetic safe and effective. The guidance, approved in July 2024 and made official in May, allows drugmakers to use lab-made alternatives instead of crab-derived lysate for new drugs with less lab testing and paperwork required. 'Basically, it leveled the playing field,' Bolden said. But it's still up to the drugmakers which to use. In May, a coalition of nonprofits that included Horseshoe Crab Recovery released the results of a survey of the 50 largest drugmakers by revenue about their use of horseshoe crab blood. Only 11 responded to acknowledge the need to switch or disclose concrete steps to actually do so. Among those rated highly by the survey were Eli Lilly, GSK, Amgen, Sanofi and Bristol Myers Squibb. One issue is that if a drugmaker wants to switch production of older drugs to a crab-free compound, it needs to do a whole new round of testing to verify that the compound works at catching contamination. 'The biggest challenges right now are legacy products,' said Elizabeth Bennett, communications director at Revive & Restore, a conservation nonprofit that helped conduct the survey. For instance, Novo Nordisk, maker of the blockbuster diabetes drug Ozempic that can cause weight loss, has phased out the use of lysate from horseshoe crabs in research, but still uses it to make existing products 'due to regulatory requirements.' In a statement to The Washington Post, the company said it has a 'road map' for 'phasing out the use of any lysate from horseshoe crab.' Johnson & Johnson and Pfizer, two of the biggest drugmakers by revenue, which each developed covid vaccines that relied on crab blood, did not complete the survey. When reached for comment by The Post, Pfizer said it is using synthetics for testing pharmaceutical water systems and has begun implementing it for some products following the U.S. Pharmacopeia decision. Johnson & Johnson did not reply to a request for comment. Eli Lilly, which rated highest in the survey, has 10 products approved that use alternatives to horseshoe crab blood for endotoxin testing. But it still has to convert some of its existing drugs. 'It's been difficult to convert that last 20 percent on legacy molecules,' Bolden said. Horseshoe crabs as a species are survivors. They made it through the asteroid strike that killed the dinosaurs as well as three of Earth's other mass extinctions. But whether the fragile web of life that depends on them can survive is more uncertain.

Panic spreads over exaggerated claims of 'tentacled' rabbits invading US

Shocking images of rabbits with deformities on their heads are spreading across platforms in posts warning about a mysterious "black tentacle virus" that can infect other species, with some calling for the animals to be shot if encountered. While the affliction is real and stems from a cancer-causing strain similar to the human papillomavirus, experts say it is nothing new and is not dangerous to humans or any other species besides rabbits. "WARNING: 'DO NOT TOUCH!' - RABBITS INFECTED WITH BLACK TENTACLE VIRUS," says an August 14, 2025 Facebook post sharing dramatic photos of rabbits with thick, spiky growths on their heads. "In Colorado, wild rabbits are being found with black, horn-like growths erupting from their heads caused by a mysterious viral infection. Officials warn it can spread to pets through direct contact. #rabbitsinfected #blacktentaclesvirus." The images circulated widely across social media, with some posts suggesting that people shoot the infected animals if encountered in the wild. "If I see tentacles sprouting out of somebody's head because they decided to touch one of the ... rabbits, click clack boom," a person says in an August 13 video viewed over 12,000 times on TikTok. Computer-generated images of bunnies with tentacles coming out of their noses later started spreading online. But wildlife experts told AFP that while the posts reference a real disease, they are exaggerated (archived here). The condition is not new and does not pose a serious threat to humans or other animal species. The reported sightings likely stem from the same few rabbits being spotted by different residents, Colorado wildlife services said, and most rabbits can live normally with the condition, which occasionally clears on its own. Advanced cases of the condition have been documented over the years. AFP was, for instance, able to identify the rabbit in one of the pictures shared online as a taxidermied cottontail from the University of Kansas Natural History Museum's collection by matching the background to that of a photo from a 2015 history blog (archived here). 'Same rabbits' Kara Van Hoose, northeast region public information officer for Colorado Parks and Wildlife, told AFP on August 13 that the pictures likely show an outbreak of Shope papillomavirus in the Fort Collins area (archived here and here). "We have started to take more reports of rabbits in the northern Colorado area affected with the virus since photos were first published last Friday," she told AFP August 13. "We're up to maybe a dozen or so reports, but it's most likely people reporting the same rabbits and not a dozen rabbits infected." The disease, spread through biting insects including fleas and ticks, causes wart-like growths, usually on the face and neck of rabbits. The animals can also clear the virus from their systems on their own in most cases, which remain benign. "We would be concerned only if the growths are on the eyes or impede the rabbit's ability to eat," Van Hoose said. The growths on rabbits have been observed in the United States for well over a hundred years, experts say, and were first documented by Richard Shope in 1933 (archived here). The cases are even thought to have inspired the American myth of the "jackalope" (archived here). "Using historical specimens in mammal collections here at the University of Kansas, we have been able to recover the virus from a hundred-year-old preserved specimen of an eastern cottontail," said Robert Timm, an associate professor emeritus from the University of Kansas who has studied the disease in rabbits (archived here). Not dangerous to humans Timm also dismissed the claims that the August 2025 sightings amount to a "recent invasion" that could threaten humans. "The virus has been in the environment for perhaps tens of thousands of years," he said August 14. Colorado Parks and Wildlife does not recommend killing the infected rabbits if found in nature, but "as with any wildlife, pets should not interact or come in contact with the rabbits," Van Hoose said. Karen Fox, a pathologist at the Colorado State University Veterinary Diagnostic Lab (archived here), confirmed the virus does not affect humans, dogs, or cats. Domesticated bunnies, however, are at risk of catching the virus from a wild infected specimen. Fox cautioned the disease "is often more severe in pet rabbits than in wild rabbits." "The best way to prevent infections in pet rabbits is to keep pet rabbits indoors, especially during the summer and fall months when insect activity is highest," she told AFP on August 15. According to University of Kansas's Timm, there are no known cases of this virus ever being transmitted to humans either from mosquitoes or rabbits. AFP previously investigated other claims about wild animals and viruses.
