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 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 Novel Genetic Clock discovers oldest known marine plant
(via sciencedaily.com) Original source An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.
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.
Published Fish out of water: How killifish embryos adapted their development
(via sciencedaily.com) Original source The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.
Published Fish in schools have an easier time swimming in rough waters
(via sciencedaily.com) Original source Swimming through turbulent water is easier for schooling fish compared to solitary swimmers, according to a new study.
Published Flapping frequency of birds, insects, bats and whales described by universal equation
(via sciencedaily.com) Original source A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, researchers report in a new study.
Published Fishy mystery of marine reptile solved
(via sciencedaily.com) Original source The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published Early summer fishing can have an evolutionary impact, resulting in smaller salmon
(via sciencedaily.com) Original source A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.
Published A novel approach to tracking conservation reveals more areas may be conserved than currently accounted for
(via sciencedaily.com) Original source An international team of conservation researchers and practitioners has developed an inclusive inventory approach for tracking global conservation areas, with an emphasis on local data and expertise. Applying this approach across the nine countries spanning the Amazon Rainforest identified a wide array of conservation areas with greater diversity and area coverage than existing tracking systems showed.
Published Exploring three frontiers in marine biomass and blue carbon capture
(via sciencedaily.com) Original source A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom.
Published Combining pest treatments may be key to helping honey bees survive the winter
(via sciencedaily.com) Original source Winters can be tough on managed honey bee colonies, with beekeepers in the United States reporting that one-third of their colonies die each winter. A new study has found that using not one but multiple pest treatments may help bees make it to spring.
Published Rocky shores of Pacific Northwest show low resilience to changes in climate
(via sciencedaily.com) Original source A 15-year period ending in 2020 that included a marine heat wave and a sea star wasting disease epidemic saw major changes in the groups of organisms that live along the rocky shores of the Pacific Northwest.
Published Using AI to decode dog vocalizations
(via sciencedaily.com) Original source Have you ever wished you could understand what your dog is trying to say to you? Researchers are exploring the possibilities of AI, developing tools that can identify whether a dog's bark conveys playfulness or aggression.
Published Human activity contributed to woolly rhinoceros' extinction
(via sciencedaily.com) Original source Researchers have discovered sustained hunting by humans prevented the woolly rhinoceros from accessing favourable habitats as Earth warmed following the Last Ice Age.
Published Key nutrients help plants beat the heat
(via sciencedaily.com) Original source Scientists have discovered some of the molecular mechanisms controlling how plants -- including important crops like soybean and rice -- will respond to rising global temperatures, finding higher temperatures make root systems grow faster, but sustaining this increased growth speed depends on high levels of nitrogen and phosphorus in the soil. The discoveries point to the necessity of nitrogen and phosphorus-rich soil to promote crop growth and create nutritious crops, in addition to aiding a mission to create more resilient crops in the face of climate change.
Published Mapping the seafloor sediment superhighway
(via sciencedaily.com) Original source A new scientific model is giving researchers an unprecedented, global look at the activities of clams, worms, and other invertebrate animals that burrow at the bottom of the ocean.
Published Wire snare removal in protected areas is labor-intensive but effective -- and essential to solving the Southeast Asian snaring crisis
(via sciencedaily.com) Original source Snaring -- a non-selective method of poaching using wire traps -- is widespread in tropical forests in Southeast Asia. Snaring decimates wildlife populations and has pushed many larger mammals to local or even global extinction. Eleven years of data from ranger patrols in the Thua Thien Hue and Quang Nam Saola Nature Reserves in Viet Nam show that intensive removal efforts are labour-intensive and costly but brought snaring down by almost 40 percent and therefore reduced imminent threats to wildlife. Further reductions were difficult to achieve despite continued removal efforts. Snare removal is therefore necessary but by itself not sufficient to save the threatened wildlife diversity in tropical forests, scientists conclude.
Published Urgent need for action now for increasing threat from invasive alien species
(via sciencedaily.com) Original source Urgent action now is needed to tackle the major and growing global issue of invasive alien species, says a team of 88 experts from 47 countries. The paper follows the (IPBES) thematic assessment report on invasive alien species and their control. The experts say co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.
Published Captivating blue-colored ant discovered in India's remote Siang Valley
(via sciencedaily.com) Original source A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
