Published Roaming seabirds need ocean-wide protection
(via sciencedaily.com) Original source Seabirds roam far and wide in the Indian Ocean -- so they need ocean-wide protection, new research shows.
Published New deep learning AI tool helps ecologists monitor rare birds through their songs
(via sciencedaily.com) Original source Researchers have developed a new deep learning AI tool that generates life-like birdsongs to train bird identification tools, helping ecologists to monitor rare species in the wild.
Published Dangerous bee virus less deadly in at least one US forest
(via sciencedaily.com) Original source Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.
Published Non-native species likely to continue spreading in North America, Australia and Europe
(via sciencedaily.com) Original source Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years
(via sciencedaily.com) Original source A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.
Published Pesticides, herbicides, fungicides detected in New York state beeswax
(via sciencedaily.com) Original source An analysis of beeswax in managed honeybee hives in New York finds a wide variety of pesticide, herbicide and fungicide residues, exposing current and future generations of bees to long-term toxicity.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published Feral horses and peatland carbon emissions
(via sciencedaily.com) Original source A ground-breaking new study has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses.
Published Yeast with an over half synthetic genome is created in the lab
(via sciencedaily.com) Original source Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.
Published Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks
(via sciencedaily.com) Original source Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.
Published Infection with common cat-borne parasite associated with frailty in older adults
(via sciencedaily.com) Original source A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gondii has previously been associated with risk-taking behavior and mental illness.
Published City and highway lights threaten mountain lion habitats
(via sciencedaily.com) Original source Artificial light pollution at night threatens mountain lion habitat, making it a factor to consider for wildlife crossings and land use, finds a new study.
Published Large herbivores such as elephants, bison and moose contribute to tree diversity
(via sciencedaily.com) Original source Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
Published New secrets about cat evolution revealed
(via sciencedaily.com) Original source By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.
Published Research outlines how sex differences have evolved
(via sciencedaily.com) Original source Researchers have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.
Published Buzz around new centralized pollination portal for better global bee data
(via sciencedaily.com) Original source A powerful new way to fill major gaps in public bee data -- including from Africa, Asia and other under-reported zones -- has been addressed with a centralized tool for consolidating bee pollinator occurrences around the globe.
Published Giant dinosaur carcasses might have been important food sources for Jurassic predators
(via sciencedaily.com) Original source Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published Dam removals, restoration project on Klamath River expected to help salmon, researchers conclude
(via sciencedaily.com) Original source The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.
Published Reverse engineering Jackson Pollock
(via sciencedaily.com) Original source Researchers combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns -- including replicating a segment of a Pollock painting -- by leveraging the same natural fluid instability that Pollock used in his work.
Published Researchers observe wolves hunting and killing sea otters and harbor seals on Alaska's Katmai coast
(via sciencedaily.com) Original source Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska's Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior.
