Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published Invasive plant time bombs: A hidden ecological threat
(via sciencedaily.com) Original source Invasive plants can stay dormant for decades or even centuries before rapidly expanding and wreaking ecological havoc, finds a new study.
Published We know the Arctic is warming -- What will changing river flows do to its environment?
(via sciencedaily.com) Original source Scientists recently combined satellite data, field observations and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 years. As expected, the overall region will be warmer and wetter, but the details -- up to 25% more runoff, 30% more subsurface runoff and a progressively drier southern Arctic, provides one of the clearest views yet of how the landscape will respond to climate change.
Published 8 in 10 lizards could be at risk due to deforestation
(via sciencedaily.com) Original source These reptiles move around tree trunks to seek warmth or shade. With trees disappearing, they would have trouble controlling their body temperature, a new study shows.
Published Scientists put forth a smarter way to protect a smarter grid
(via sciencedaily.com) Original source Scientists have put forth a new approach to protect the electric grid, creating a tool that sorts and prioritizes cyber threats on the fly.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests
(via sciencedaily.com) Original source After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published Unlocking the potential of lithium-ion batteries with advanced binders
(via sciencedaily.com) Original source Lithium-ion batteries employ binders that encounter challenges such as poor conductivity and expansion during charging. In a recent study, scientists have developed a high-performing binder using poly(vinylphosphonic acid) for silicon oxide-based anodes in lithium-ion batteries. This binder offers enhanced performance as demonstrated by the superior durability, and discharging capacity of the anodes compared to conventional options. With patents filed internationally, this technology holds promise for broader applications in electric vehicles and beyond.
Published Lithium-ion batteries from drones might find second lives in less 'stressful' devices
(via sciencedaily.com) Original source Taking flight can be stressful -- especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device's overall lifespan. Research shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the 'stressed out' batteries could also have second lives in less strenuous applications.
Published Hurricanes and power grids: Eliminating large-scale outages with a new approach
(via sciencedaily.com) Original source Large scale-power outages caused by tropical cyclones can be prevented almost entirely if a small but critical set of power lines is protected against storm damages, a new study finds. Scientists developed a new method that can be used to identify those critical lines and increase the system's resilience.
Published Improving energy security with policies focused on demand-side solutions
(via sciencedaily.com) Original source Energy systems essential to supporting our everyday activities face increasing threats from wars, pandemics, climate change, and other unexpected events. An international team of researchers found that demand-oriented solutions have a significantly greater potential to reduce our vulnerability to energy crises compared to supply measures.
Published Microbial viruses act as secret drivers of climate change
(via sciencedaily.com) Original source Scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.
Published Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature
(via sciencedaily.com) Original source More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.
Published Genetic research revealed several new fern species in tropical America
(via sciencedaily.com) Original source Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Published A new plant's name that tells a story
(via sciencedaily.com) Original source A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.
Published Bottlenecks and beehives: How an invasive bee colony defied genetic expectations
(via sciencedaily.com) Original source An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.
Published The veil varies more than the threat: Predator selection on variability in camouflage and warning signals
(via sciencedaily.com) Original source Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.
Published Older African elephants will be most severely affected by the changing climate
(via sciencedaily.com) Original source Older elephants in East Africa will be most severely impacted by climate change, threatening the long-term survival of this vulnerable African mammal, according to a new study.
Published African great apes predicted to see frequent extreme climate events in the next 30 years
(via sciencedaily.com) Original source African apes are already being exposed to climate change impacts, and will experience extreme events such as wildfires, heatwaves and flooding more frequently in the next 30 years, according to a new study.
Published Study reveals accelerated soil priming under climate warming
(via sciencedaily.com) Original source A new study highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere.
Published Study finds drought fuels invasive species after wildfires
(via sciencedaily.com) Original source Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
