Published Top 10 climate science insights unveiled
(via sciencedaily.com) Original source A new report equips policymakers with the latest and most pivotal climate science research from the previous 18 months, synthesized to help inform negotiations at COP28 and policy implementation through 2024 and beyond.
Published In hotter regions, mammals seek forests, avoid human habitats
(via sciencedaily.com) Original source As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.
Published Deep sea sensor reveals that corals produce reactive oxygen species
(via sciencedaily.com) Original source A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
Published Strange burn: New research identifies unique patterns in Utah wildfires
(via sciencedaily.com) Original source Utah's variable topography produces a tremendous range of wildfire behavior, according to new research.
Published More than a meteorite: New clues about the demise of dinosaurs
(via sciencedaily.com) Original source What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.
Published Earliest-known fossil mosquito suggests males were bloodsuckers too
(via sciencedaily.com) Original source Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthparts, suggesting they likely sucked blood. That's noteworthy because, among modern-day mosquitoes, only females are hematophagous, meaning that they use piercing mouthparts to feed on the blood of people and other animals.
Published Himalayan glaciers react, blow cold winds down their slopes
(via sciencedaily.com) Original source Himalayan Glaciers fight back to preserve themselves, but for how long? An international team of researchers explains a stunning phenomenon: rising global temperatures have led Himalayan glaciers to increasingly cool the air in contact with the ice surface. The ensuing cold winds might help cool the glaciers and preserve the surrounding ecosystems. The results were found across the Himalayan range.
Published Crocodile family tree mapped: New light shed on croc evolution
(via sciencedaily.com) Original source Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
Published Public gardens contribute to invasives problem
(via sciencedaily.com) Original source Some nonnative plants cultivated in public gardens or arboretums are escaping to become invasive in wild forests.
Published Botany must feature more prominently on the school curriculum to promote awareness of climate change, study warns
(via sciencedaily.com) Original source Children must be taught more about the importance of plants if education about climate change and sustainability is to be effective, experts have warned.
Published Ash can fertilize the oceans
(via sciencedaily.com) Original source Flames roared through Santa Barbara County in late 2017. UC Santa Barbara canceled classes, and the administration recommended donning an N95, long before the COVID pandemic made the mask a household item. Smoke and ash choked the air, but the Thomas Fire's effects weren't restricted to the land and sky. Huge amounts of ash settled into the oceans, leaving researchers to wonder what effect it might have on marine life.
Published Study identifies key algae species helping soft corals survive warming oceans
(via sciencedaily.com) Original source During a two-year survey of soft corals in the Florida Keys, scientists identified three species of octocorals that have survived heat waves. While the coral animal itself may be heat tolerant, scientists concluded that the symbiotic algae inside the coral serve as a protector of sorts.
Published Genomic study sheds light on how carnivorous Asian pitcher plants acquired signature insect trap
(via sciencedaily.com) Original source Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
Published Snake skulls show how species adapt to prey
(via sciencedaily.com) Original source By studying the skull shapes of dipsadine snakes, researchers have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources.
Published Illuminating the benefits of marine protected areas for ecotourism, and vice versa
(via sciencedaily.com) Original source As California, the U.S. and the world work to make good on commitments to conserve 30% of oceans and lands by 2030, all strategies are on the table -- and under the microscope. When it comes to the ocean, one valuable tool is marine protected areas (MPAs), regions that are defined, designated and managed for long-term conservation. Among other benefits, MPAs protect habitats and promote species diversity. They also hold value for communities and industries.
Published Decoding past climates through dripstones
(via sciencedaily.com) Original source A recent study demonstrates how dripstones can be crucial for reconstructing past climates. The new approach can provide a detailed picture of the climate around early human occupations in South Africa.
Published Rare ant species rediscovered in North Carolina trees
(via sciencedaily.com) Original source There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.
Published how far can the wind can carry a plant's seeds? New model
(via sciencedaily.com) Original source Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.
Published Identifying Australia's most elusive birds
(via sciencedaily.com) Original source Scientists have analyzed more than 3.8 million volunteer hours of birdwatching data to identify Australia's most elusive species.
Published Landscape dynamics determine the evolution of biodiversity on Earth
(via sciencedaily.com) Original source A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.
