Published Wild chimpanzees seek out medicinal plants to treat illness and injuries
(via sciencedaily.com) Original source Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Newly discovered dinosaur boasts big, blade-like horns
(via sciencedaily.com) Original source A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published Wild yeasts from Patagonia could yield new flavors of lagers
(via sciencedaily.com) Original source New strains of yeast for brewing lager beers, created by hybridizing wild strains of yeast from Patagonia with brewer's yeast, can yield novel flavors and aromas, researchers report.
Published Insecticides contributed to loss of butterflies across American Midwest, study finds
(via sciencedaily.com) Original source Insecticide use is a major factor causing a decrease in the size and diversity of butterfly populations across the US Midwest, according to a new study.
Published Wooden surfaces may have natural antiviral properties
(via sciencedaily.com) Original source Viruses, including the coronavirus that causes COVID-19, can get passed from person to person via contaminated surfaces. But can some surfaces reduce the risk of this type of transmission without the help of household disinfectants? Wood has natural antiviral properties that can reduce the time viruses persist on its surface -- and some species of wood are more effective than others at reducing infectivity.
Published Non-native plants and animals expanding ranges 100 times faster than native species
(via sciencedaily.com) Original source An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.
Published Fishy parenting? Punishing offspring encourages cooperation
(via sciencedaily.com) Original source Scientists discovered that Neolamprologus savoryi fish use punishment to encourage offspring to cooperate in brood care, revealing advanced cognitive abilities previously thought unique to higher vertebrates. This study highlights that punishment for promoting cooperation exists beyond human societies, prompting a reevaluation of animal intelligence.
Published Restored rat-free islands could support hundreds of thousands more breeding seabirds
(via sciencedaily.com) Original source Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.
Published 'Lost' birds list will aid in protecting species
(via sciencedaily.com) Original source A group of scientists has released the first comprehensive list of birds that haven't been documented with sound or video in more than a decade.
Published Tiny New Zealand bird delivers a lesson in birdsong evolution
(via sciencedaily.com) Original source Scientists are rethinking the evolution of vocal learning in birds. New Zealand's smallest bird, the rifleman or titipounamu, may have a rudimentary version of the talent possessed by parrots, hummingbirds and songbirds.
Published The scary, yet promising world of phages, the pathogen's pathogen
(via sciencedaily.com) Original source Researchers are unlocking the mystery of how bacteria harness viruses to wipe out the competition. The answers could help spur the development of alternatives to antibiotics.
Published Paleontology: New fossil fish genus discovered
(via sciencedaily.com) Original source Paleontologists have identified a new genus of fossil goby, revealing evolutionary secrets of a lineage that stretches back millions of years.
Published Outdoor recreation noise affects wildlife behavior and habitat use, study finds
(via sciencedaily.com) Original source We may go to the woods seeking peace and quiet, but are we taking our noise with us? A recent study indicates that the answer is yes -- and that this noise can trigger a fear response, as if escaping from predators. This new science calls into question whether otherwise high-quality habitat truly provides refugia for wildlife when recreationists are present and underscores the challenges land managers face in balancing outdoor recreational opportunities with wildlife conservation.
Published New way to spot beetle-killed spruce can help forest, wildfire managers
(via sciencedaily.com) Original source A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.
Published Humans are the elephant in the room where conservation is debated
(via sciencedaily.com) Original source Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published Specialist and migratory birds at greater risk under climate change
(via sciencedaily.com) Original source Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.
Published Lazy predator: A new species of mountain pitviper from China
(via sciencedaily.com) Original source Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.
Published Early life exposure to weed pollen could increase childhood asthma risk
(via sciencedaily.com) Original source A study has found children who are exposed to tree and weed pollen in urban environments are at increased risk of respiratory health problems, including asthma. While green areas in urban settings decrease exposure to air pollution, allow kids to be active, and offer positive contact to a diverse microbiota -- which in turn may help the positive development of a child's immune system -- they can also lead to the development of childhood asthma. Thankfully, trees can help mitigate this effect to some degree, thanks to their canopy.
Published Two can play that game: juvenile dolphins who play together are more successful as adults
(via sciencedaily.com) Original source Juvenile social play predicts adult reproductive success in male bottlenose dolphins, a new study has found.
Published Elephants have names for each other like people do, new study shows
(via sciencedaily.com) Original source Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans.
