Published Managing domestic and wildcats is likely to remain fraught, new research warns
(via sciencedaily.com) Original source Current efforts to protect and restore native biodiversity is being threatened by difficulties in identifying wild and domestic cats, and categorization is likely to remain fraught for the foreseeable future, experts have warned.
Published New Antarctic extremes 'virtually certain' as world warms
(via sciencedaily.com) Original source Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.
Published Bat activity lower at solar farm sites
(via sciencedaily.com) The activity level of six bat species was significantly reduced at solar farm sites, researchers have observed.
Published Study reveals successful strategies for removing invasive caimans from Florida Everglades
(via sciencedaily.com) A new study reveals how a succession of strategies can take control of an invasive species population.
Published Kordofan giraffes face local extinction if poaching continues
(via sciencedaily.com) Original source Poaching of two Critically Endangered Kordofan giraffes per year could result in extinction in just 15 years within Cameroon's Bénoué National Park without intervention.
Published Tropical trees use social distancing to maintain biodiversity
(via sciencedaily.com) Original source Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
Published Scientists dig into wildfire predictions, long-term impacts
(via sciencedaily.com) Original source Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.
Published Nuisance vegetation removal in Senegalese waterways reduces the overall prevalence of parasitic infections and increases local food production
(via sciencedaily.com) Original source It's an elegant solution: Remove the habitat of a parasite-carrying aquatic snail and reduce the level of infection in the local community; all while generating more feed and compost for local farmers.
Published Scientists vacuum animal DNA from air in a Danish forest
(via sciencedaily.com) Original source Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.
Published Flying reptiles had nurturing parental style
(via sciencedaily.com) Original source Did the pterosaurs, flying reptiles from the days of the dinosaurs, practice parental care or not? New research shows that pterosaurs were indeed caring parents -- but only the larger species.
Published Unusual fossil shows rare evidence of a mammal attacking a dinosaur
(via sciencedaily.com) Original source Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory behavior by a mammal on a dinosaur. The fossil's presence challenges the view that dinosaurs had few threats from their mammal contemporaries during the Cretaceous, when dinosaurs were the dominant animals.
Published Ice Age saber-tooth cats and dire wolves suffered from diseased joints
(via sciencedaily.com) Original source Ice Age saber-tooth cats and dire wolves experienced a high incidence of bone disease in their joints, according to new research.
Published Tiny scales reveal megalodon was not as fast as believed, but it had a mega-appetite explaining its gigantism
(via sciencedaily.com) Original source A new study reveals the iconic extinct Megalodon, or 'megatooth shark', was a rather slow cruiser that used its warm-bloodedness to facilitate digestion and absorption of nutrients.
Published Evolutionary origins of the pygmy right whale
(via sciencedaily.com) Original source Researchers have finally settled a decades-long dispute about the evolutionary origins of the pygmy right whale.
Published Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died
(via sciencedaily.com) Original source Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
Published A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
(via sciencedaily.com) Original source The lower jaws of lizards, birds, fish and even dinosaurs are comprised of multiple bones per side. Yet mammals diverged from all other vertebrates and settled on just one bone, repurposing the extra bones into a more elaborate inner ear, perhaps the better to hear. The single bone per side, fused in primates into one jawbone, makes the jaw more rigid. A paleontologist asks, Did the stiffer, rigid jaw make mammals more successful?
Published Humans' ancestors survived the asteroid impact that killed the dinosaurs
(via sciencedaily.com) Original source A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.
Published Megalodon was no cold-blooded killer
(via sciencedaily.com) Original source How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch.
Published How coral reefs can survive climate change
(via sciencedaily.com) Original source Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
Published Human impact on wildlife even in protected areas
(via sciencedaily.com) Original source The largest long-term standardized camera-trap survey to date finds that human activity impacts tropical mammals living in protected areas and sheds light on how different species are affected based on their habitat needs and anthropogenic stressors.
