Published Researchers observe wolves hunting and killing sea otters and harbor seals on Alaska's Katmai coast
(via sciencedaily.com) Original source Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska's Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior.
Published Australasia's hidden pollination crisis could threaten biodiversity and food security
(via sciencedaily.com) Original source Australasia's hidden pollination crisis, mirroring global threats, could pose a significant risk to regional biodiversity and food security, new research has found.
Published Amphibians have one more thing to worry about--mercury
(via sciencedaily.com) Original source The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.
Published Low-income countries could lose 30% of nutrients like protein and omega-3 from seafood due to climate change
(via sciencedaily.com) Original source The nutrients available from seafood could drop by 30 per cent for low-income countries by the end of the century due to climate change, suggests new research. That's in a high carbon emissions and low mitigation scenario, according to the study. This could be reduced to a roughly 10 per cent decline if the world were to meet the Paris Agreement targets of limiting global warming to 1.5 to 2 degrees Celsius -- which recent reports have shown we're not on track to achieve.
Published New species of mosasaur named for Norse sea serpent
(via sciencedaily.com) Original source Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.
Published Increasing risk of invasive species colonization on marine debris
(via sciencedaily.com) Original source A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.
Published Protein root discovery seals future of climate-proof plants
(via sciencedaily.com) Original source Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers.
Published Discovery of three novel minorisa species, the smallest predatory marine picoplankton
(via sciencedaily.com) Original source Researchers have made a significant discovery by identifying and characterizing three novel species within the Minorisa genus of marine picoplankton. Before this study, only one species of Minorisa was recognized. This finding reveals previously unseen diversity of Minorisa, thereby enhancing species identification and our understanding of its ecological functions in marine ecosystems.
Published Endangered whales live in area earmarked for gas exploration
(via sciencedaily.com) Original source Endangered whales and dolphins live year-round in an area of the Mediterranean earmarked for oil and gas exploration, new research shows.
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 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 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 Scientists uncover cause of mysterious deaths of elephants in Zimbabwe
(via sciencedaily.com) Original source A bacterium, closely associated with deadly septicaemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighboring countries. The findings place infectious diseases on the list of pressures on African elephants, whose populations continue to be under threat.
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 Discovery finds ferns produce crop-saving insecticide
(via sciencedaily.com) Original source Researchers have solved the structure of a novel insecticidal protein that is effective in protecting major crop plants like corn and soybean from pests and is naturally produced by ferns.
Published Plants transformed into detectors of dangerous chemicals
(via sciencedaily.com) Original source What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
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.
