Videos From the Amazon Reveal an Unexpected Animal Friendship
Researchers at Cocha Cashu Biological Station in southeastern Peru set up a camera trap to study bird behavior, but they got a surprise guest appearance instead: an ocelot trailing an opossum through the jungle at night. The ocelot, a wild cat slightly larger than a house cat, and the common opossum, a marsupial, are usually predator and prey. But in this video, they moved in tandem.
'We were skeptical about what we had seen,' said Isabel Damas-Moreira, behavioral ecologist at Bielefeld University in Germany. Perhaps the ocelot was shadowing its dinner-to-be to learn about its behavior, they wondered, although that didn't explain the opossum's laid-back behavior. Then came a second clip: the same odd couple wandering back along the trail minutes later.
'Like two old friends walking home from a bar,' Dr. Damas-Moreira said.
Intrigued, they contacted researchers in other parts of the Amazon who turned up three additional, nearly identical videos from different locations and years.
Dr. Damas-Moreira and her colleagues then set up an experiment, which they described last month in the journal Ecosphere. They left strips of fabric infused with ocelot scent, puma scent and a control in front of camera traps.
Opossums visited the ocelot scent 12 times, often lingering to rub against, sniff or bite the fabric. The puma scent attracted just one brief visit.

These 'crazy' invasive Florida pests attack mammals, birds and create giant supercolonies
Move over Burmese pythons and iguanas. This Florida invasive species numbers in the millions, asphyxiates its prey and creates huge supercolonies that are nearly impossible to eradicate. Meet tawny crazy ants. They get their name from their erratic movements, especially while foraging, and are native to South America but spread to the southern U.S. in the late 1990s. According to the USDA, tawny crazy ants in Florida are part of a super colony that spreads across the southern U.S. They lack territorial behavior, which enables the creation of gigantic supercolonies, whose need for resources drives out local wildlife and brings them into direct conflict with humans. They can invade homes where they are drawn to and damage electrical equipment, and can make yards uncomfortable for residents to enjoy. In areas of the country with severe tawny crazy ant infestations, they kill or displace local wildlife, including other ant species, even fire ants. 'There's no insect noise and there's no bird noise,' University of Texas ecologist Edward LeBrun told Science. According to Texas A&M University's Urban and Structural Entomology Program, after experiencing the tawny crazy ant, most residents prefer the fire ant. Tawny crazy ants bite and excrete formic acid Tawny crazy ants bite and excrete formic acid, which they use like venom. What do tawny crazy ants in Florida eat? According to the University of Florida's Institute of Food and Agricultural Sciences (IFAS), tawny crazy ants prey on live animals, and scavenge from dead animals. They eat caterpillars, beetles, termites, wasps and spiders, or even small animals such as rabbits, birds, lizards, and domestic animals, which usually die due to asphyxia. Tawny crazy ants are capable of forcing birds from their nests and blinding young rabbits with their acid, Smithsonian Magazine reported. They can attack crops, domestic animals and honeybee hives, and take over the nesting sites of other ant species, including fire ants. Where in Florida are tawny crazy ants found? See map According to IFAS, by 2012, tawny crazy ants were found in 24 counties in Florida listed below, with infestations spreading. This can be expected in any county in Florida, IFAS reported. Alachua Brevard Broward Clay Collier DeSoto Duval Hardee Hillsborough Indian River Lee Manatee Marion Martin Miami-Dade Orange Palm Beach Pasco Pinellas Polk Saint Johns Saint Lucie Sarasota What do tawny crazy ants look like? The Urban and Structural Entomology Program at Texas A&M University describes tawny crazy ants as follows: Coloration: Adult colony members, including queens, males and workers, are reddish-brown (although lightness or darkness of their body color may vary) Size: Worker ants are all similar in size (they are monomorphic), with a body length of 1/8 inch. Worker ants have long legs and antennae and their bodies have numerous, long, coarse hairs. The antenna have 12-segments with no club. There is a small circle of hairs (acidopore) present at tip of the abdomen (as opposed to the typical stinger found in many ants), a characteristic of formicine ants (found within the Formicinae subfamily). How to get rid of tawny crazy ants around your home Management of this ant will most likely require the services of a professional pest control company that practices integrated pest management (IPM). According to UF, 100% eradication of this ant is not probable in areas where it is established. However, population suppression is possible. Tawny crazy ant prevention Schedule regular trash pick-up. Keep trash cans clean and stored away from the home. Remove leaf litter, fallen branches, and other yard debris. Keep hedges and trees trimmed so that they do not touch the home. Eliminate or reduce possible food, water, and nesting sources. Remove trash regularly and keep trash receptacles clean. Do not leave dirty dishes in the sink. Clean up spills immediately. Place food items in the refrigerator or in sealed containers. Pick up pet food bowls when your pet is not eating. Exclusion To prevent ants from entering a home: Walk around the outside of the home and locate potential entry points (cracks, crevices, spaces around windows and doors). Locate indoor entry points, paying particular attention to windows, doors, and plumbing and utility penetrations. Use an appropriate sealant. Replace door thresholds and weather stripping as needed. If you can see light from the outside while you are standing inside, it is enough of a gap for ants and other pests to enter.

Researchers make stunning discovery after studying wildlife living near wineries: 'Can be further enhanced'
Researchers make stunning discovery after studying wildlife living near wineries: 'Can be further enhanced' A team of researchers from the HUN-REN Center for Ecological Research and the University of Milan recently established a connection between vineyard ecosystems and local bird and bat species. The HUN-REN Center's mission is to support biodiversity research, and it is resolute in the understanding that a more informed public can make better environmental decisions. Published in the Journal of Applied Ecology, their study addressed one part of the ongoing problem of habitat reconfiguration — that is, when natural landscapes are repurposed into human-oriented mechanisms. In an agricultural context specifically, it's crucial that we maintain a balance between crop yields for human needs and ecological sustainability, a balance these researchers aimed to identify within vineyards. In addition to being land-replenishing pollinators, birds and bats serve as natural predators, keeping pests in check while supporting beneficial arthropod species. Per it's a predisposition that can serve to our benefit as well, when it comes to vineyards and other agricultural endeavors — and by monitoring and recording bird and bat activity against arthropod activity across various Hungarian vineyards, these researchers worked to prove just that. By demonstrating that predatory birds and bats regulate pest populations on behalf of farmers, the team is encouraging the protection of these species by vineyard management, hoping that humans can work with birds and bats rather than allowing vineyards to devolve into sites of human-animal conflict. The researchers called for the sustenance of these agricultural projects without the use of synthetic pesticides — after all, why turn to polluting and often harmful chemicals when the natural solution is just as effective, requires fewer resources, and brings about less contamination to the air and soil? Uncontrolled pesticide use not only leaks toxic contaminants into the soil to kill pests, but also leaves lingering traces in the affected plants and the atmosphere of the region, posing risks to human health. Exposure through the food we eat and the air we breathe leaves us vulnerable to a variety of health concerns, ranging from reproductive damage to cancers. Moreover, the ripple effects of pesticides have lowered biodiversity around the world, destablizing ecosystems. The HUN-REN Center seeks to make its ecological findings more mainstream, bridging the gap between the discipline of environmental research and the average individual. If more of us can become cognizant of the issues infiltrating every step of our daily lives — from the pollutants we consume to the wine we drink — we can prove better-equipped to encourage our environmental authorities to address them. HUN-REN, specifically, is involved closely with the European Union. Research author Péter Batáry summed it up for "Pest control services can be further enhanced through organic management, which avoids herbicides and synthetic insecticides, thereby facilitating the colonization of beneficial arthropods and strengthening pest predation pressure in vineyards."

Scientist makes astonishing discovery after observing US-Mexico border wall with motion-sensing cameras: 'Beautiful region'
Scientist makes astonishing discovery after observing US-Mexico border wall with motion-sensing cameras: 'Beautiful region' Much has been reported about the border wall between Mexico and the United States. It is designed to separate the two nations and prevent people from passing between the countries unchecked. However, a study has outlined the large and unintended consequences of the wall on nature and wildlife in the area. What's happening? As Vox detailed, the border wall in the southwest United States covering parts of Arizona and New Mexico also cuts through a swath of rugged natural terrain. The area is home to a diverse ecosystem of plants and animals that have been heavily impacted by the wall. Ganesh Marín, who was a doctoral researcher at the University of Arizona, set up 85 motion-sensor cameras in the region. The cameras captured various species, including ocelots, jaguars, beavers, and black bears. All in all, Marín ended up with about 21,000 clips. Why is this study concerning? The videos suggest the animals are avoiding the wall as much as possible and changing their behaviors in response. This is frustrating because the animals need to be able to wander the area freely to find water, food, and mates. Unfortunately, this is not the only way the wall has caused a problem for local wildlife. Last year, when fires swept through parts of Texas, frogs, snakes, and other animals close to the border couldn't escape because they were blocked by a section of the border wall. Ecosystems are already under threat because of rising global temperatures. According to the United Nations, many animals have already lost their habitats due to changing climates as well as the overdevelopment of land. The border wall only exacerbates an already growing problem. What's being done to protect wildlife? One way for people to fight back is to take local action in their own communities to ensure wildlife and ecosystems are protected. Another way is to vote for candidates who recognize the importance of these environmental issues, regardless of their side of the political aisle. As Marín noted, "Amazing wildlife is present in the borderlands due to the binational efforts to protect and restore the flow of life between both countries. We should not define this beautiful region and the creatures that roam by the existence of an imposed division." Do you think America is in a housing crisis?
