Published Mosaic grassland landscapes are the most beneficial
(via sciencedaily.com) Original source Grassland provides many services for humans, animals and nature, such as feed production, carbon storage and recreation. Researchers spent two years investigating permanent grassland, its utilization, soils and plant communities in order to quantify the resulting ecosystem services. Grassland performs best when different types of use such as meadows, pastures and unfertilized extensive grassland exist together in a mosaic landscape.
Published WASP-193b, a giant planet with a density similar to that of cotton candy
(via sciencedaily.com) Original source Astronomers have just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant Sun-like star.
Published Century of statistical ecology reviewed
(via sciencedaily.com) Original source A special review examines highly-cited papers in statistical ecology. The review, which covers a century of research, details how models and concepts have evolved alongside increasing computational power.
Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published Squeezed by neighbors, planet glows with molten lava
(via sciencedaily.com) Original source Astrophysicists discovered that an exoplanet is covered with so many active volcanoes that seen from a distance it would take on a fiery, glowing-red hue.
Published Transformation of ocean management is underway
(via sciencedaily.com) Original source Despite its benefits and recognition as a keystone practice of ocean stewardship and conservation, adoption of ecosystem-based management has been slow to take hold. To support this change in ocean management, a group of researchers and practitioners investigated the global progress of marine EBM initiatives.
Published Rapid oyster reef restoration gives hope for repairing the sea
(via sciencedaily.com) Original source After a century of functional extinction on the Australian mainland, a Flat oyster reef has been successfully restored along a metropolitan Adelaide coastline.
Published Saturated soils could impact survival of young trees planted to address climate change
(via sciencedaily.com) Original source New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.
Published Astrophysicists discover a novel method for hunting the first stars
(via sciencedaily.com) Original source A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.
Published Possible atmosphere surrounding rocky exoplanet
(via sciencedaily.com) Original source Researchers may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.
Published Ozone's influence on exoplanetary climate
(via sciencedaily.com) Original source In the quest for life beyond our solar system, a new study delves into the atmospheric dynamics of planet Proxima Centauri b, illuminating ozone's pivotal role in shaping planetary climates. This research signifies a significant leap forward in our understanding of habitable exoplanets.
Published Limited adaptability makes freshwater bacteria vulnerable to climate change
(via sciencedaily.com) Original source Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.
Published Venus has almost no water: A new study may reveal why
(via sciencedaily.com) Original source Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.
Published Hubble views a galaxy with a voracious black hole
(via sciencedaily.com) Original source Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).
Published New discoveries about Jupiter's magnetosphere
(via sciencedaily.com) Original source New discoveries about Jupiter could lead to a better understanding of Earth's own space environment and influence a long-running scientific debate about the solar system's largest planet.
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published To bend the curve of biodiversity loss, nature recovery must be integrated across all sectors
(via sciencedaily.com) Original source The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active 'mainstreaming' or integration of biodiversity targets into policies and plans across relevant sectors. However, research suggests that this has until now been largely ineffective due to non-binding commitments, vaguely formulated targets, 'add-on' biodiversity initiatives, and too few resources. 'Top down regulation is also needed,' say the authors.
Published Webb telescope probably didn't find life on an exoplanet -- yet
(via sciencedaily.com) Original source Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence of the life-produced gas.
Published Earth-like environment likely on ancient Mars
(via sciencedaily.com) Original source A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake.
Published Big data reveals true climate impact of worldwide air travel
(via sciencedaily.com) Original source A new study that looked at nearly 40 million flights in 2019 calculated the greenhouse gas emissions from air travel for essentially every country on the planet. At 911 million tons, the total emissions from aviation are 50 per cent higher than the 604 million tons reported to the United Nations for that year.
