Published Marine protected areas and climate change
(via sciencedaily.com) Original source New research offers a way to build climate resilience into the designs of ocean and coastal areas intended to protect marine species. The researchers recommend establishing numerous marine protected areas across political borders, starting with the Southern California Bight.
Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com) Original source The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published On the trail of the silver king: Researchers reveal unprecedented look at tarpon migration
(via sciencedaily.com) Original source New research unveils a dataset, gathered over five years, that gives the finest-grained detail into the timing and spatial extent of tarpon migration. The work leveraged networks of thousands of acoustic receivers that tracked 200 tarpon over more than five years. One of the key findings is that there are two distinct subgroups of tarpon, which has immediate implications for efforts to conserve the fish, known to anglers as the 'Silver King.'
Published UK air pollution regulations will reduce deaths, but do little to protect ecosystems
(via sciencedaily.com) Original source Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
Published Single model predicts trends in employment, microbiomes, forests
(via sciencedaily.com) Original source Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests. The model will help economists, ecologists, public health authorities and others predict and respond to variability in multiple domains.
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 Report warns about risk tipping points with irreversible impacts on people and planet
(via sciencedaily.com) Original source A new report finds that drastic changes are approaching if risks to our fundamental socioecological systems are not addressed. The Interconnected Disaster Risks Report 2023 warns of six risk tipping points ahead of us: Accelerating extinctions; Groundwater depletion; Mountain glaciers melting; Space debris; Unbearable heat; and an Uninsurable future.
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 Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com) Original source Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Research reveals three new marsupial species -- though all likely extinct
(via sciencedaily.com) Original source The exciting discovery of three new species of a small Australian marsupial has been tempered by the sad fact that each of the newly identified species of mulgara is likely already extinct.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com) Original source A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
Published Climate report: 'Uncharted territory' imperils life on Earth
(via sciencedaily.com) Original source An international coalition of climate scientists says that the Earth's vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
Published Tiny spirits roam the corals of Japan -- two new pygmy squids discovered
(via sciencedaily.com) Original source Named after Japanese folklore, two cephalopod species have been discovered in the coastal waters of the Okinawa Islands.
Published Light, freshwater sticks to Greenland's east coast
(via sciencedaily.com) Original source Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island. In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.
Published Climate is increasing risk of high toxin concentrations in Northern US lakes
(via sciencedaily.com) Original source As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.
Published New study shows surprising effects of fire in North America's boreal forests
(via sciencedaily.com) Original source Using satellite images, researchers found that fires in North America's boreal forest may be changing the environment in ways that researchers didn't previously anticipate.
Published Soft, living materials made with algae glow under stress
(via sciencedaily.com) Original source Researchers have developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego's beaches.
Published Ancient sea monster remains reveal oldest mega-predatory pliosaur
(via sciencedaily.com) Original source The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.
Published Land use: Producing more food and storing more carbon
(via sciencedaily.com) Original source Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.
