Published Sediment core analysis supports new epoch characterized by human impact on planet
(via sciencedaily.com) Original source Scientists analyzed open-source data to track vegetation changes across North America since the end of the Pleistocene Epoch, and conclude that humans have had as much of an impact on the landscape as the retreat of the glaciers at the end of the Ice Age.
Published New study finds hidden trees across Europe: A billion tons of biomass is overlooked today
(via sciencedaily.com) Original source Through satellite imaging a new AI driven mapping of biomass and CO2 storage shows that a huge number of trees are overlooked in Europe's urban, rural, and agricultural areas. Across Europe, researchers have discovered a billion tons of hidden biomass.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds
(via sciencedaily.com) Original source While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published Cut emissions and improve farming to protect wilderness
(via sciencedaily.com) Original source Humanity must cut carbon emissions and use farmland more efficiently to protect our planet's remaining wilderness, new research shows.
Published Drought conditions expose rivers to hotter water temperatures
(via sciencedaily.com) Original source A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.
Published New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com) Original source The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published AI models identify biodiversity from animal sounds in tropical rainforests
(via sciencedaily.com) Original source Animal sounds are a very good indicator of biodiversity in tropical reforestation areas. Researchers demonstrate this by using sound recordings and AI models.
Published Coffee and cocoa plants at risk from pollinator loss
(via sciencedaily.com) Original source Tropical crops such as coffee, cocoa, watermelon and mango may be at risk due to the loss of insect pollinators, finds a new study.
Published Tens of thousands of endangered sharks and rays caught off Congo
(via sciencedaily.com) Original source Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows.
Published Remains of artificial turf is an important source of pollution of the aquatic environment
(via sciencedaily.com) Original source Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.
Published Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats
(via sciencedaily.com) Original source Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.
Published Shining a light on tiny, solar-powered animals
(via sciencedaily.com) Original source Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Invertebrate biodiversity is improving in England's rivers, long-term trends show
(via sciencedaily.com) Original source Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say
(via sciencedaily.com) Original source The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.
Published Improved mangrove conservation could yield cash, carbon, coastal benefits
(via sciencedaily.com) Original source A shift in the way we think about the benefits mangroves provide to coastal regions could yield significant economic and biodiversity gains and protect millions from flooding, research has revealed.
Published Groundbreaking mathematical proof: New insights into typhoon dynamics unveiled
(via sciencedaily.com) Original source A research team has provided irrefutable proof that certain spherical vortices exist in a stable state.
Published A turtle time capsule: DNA found in ancient shell
(via sciencedaily.com) Original source Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide.
Published Sperm swimming is caused by the same patterns that are believed to dictate zebra stripes
(via sciencedaily.com) Original source Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail moves.
Published Plastic cloud: New study analyzes airborne microplastics in clouds
(via sciencedaily.com) Original source Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.
