Published Greenhouse gases in oceans are altered by climate change impact on microbes
(via sciencedaily.com) Original source The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published The ocean may be storing more carbon than estimated in earlier studies
(via sciencedaily.com) Original source The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. Scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed. Plankton gobble up carbon dioxide and, as they grow, convert it into organic tissue via photosynthesis.
Published Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species
(via sciencedaily.com) Original source Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.
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 'Shocking' discovery: Electricity from electric eels may transfer genetic material to nearby animals
(via sciencedaily.com) Original source Researchers have discovered that electric eels can alter the genes of tiny fish larvae with their electric shock. Their findings help to better understand electroporation, a method by which genes can be transported using electricity.
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 New study identifies the greatest threat to wildlife across North America and Canada: people
(via sciencedaily.com) Original source A biology student studied more than 600,000 wildlife rehabilitation center records to look at the human impact on wild animals, from lead poisonings to window strikes to vehicle collisions.
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 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 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 A mixed origin made maize successful
(via sciencedaily.com) Original source Maize is one of the world's most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research shows that all modern maize descends from a hybrid created just over 5000 years ago in central Mexico, thousands of years after the plant was first domesticated.
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.
