Published Some species may tolerate climate change better than expected
(via sciencedaily.com) Original source A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.
Published Research to uncover the impact of water use in the Colorado River Basin
(via sciencedaily.com) Original source Persistent overuse of water and long-term drought has depleted the Colorado River and highlighted the need for a comprehensive understanding of how waters are allocated and used to develop effective management strategies.
Published Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research
(via sciencedaily.com) Original source 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
Published The secret sex life of coral revealed
(via sciencedaily.com) Original source Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.
Published New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
(via sciencedaily.com) Original source As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gasses to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from these perpetually frozen lands could be on par with emissions from large industrial countries. However, new research led by a team of microbiome scientists suggests those estimates might be too low.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Warmer wetter climate predicted to bring societal and ecological impact to the Tibetan Plateau
(via sciencedaily.com) Original source According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.
Published The global clean water crisis looms large
(via sciencedaily.com) Original source Water scarcity will intensify with climate and socioeconomic change, disproportionately impacting populations located in the Global South.
Published Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall
(via sciencedaily.com) Original source The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Published Future climate impacts put whale diet at risk
(via sciencedaily.com) Original source A new study predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume.
Published Beach erosion will make Southern California coastal living five times more expensive by 2050, study predicts
(via sciencedaily.com) Original source Southern California's iconic sandy coastlines are vanishing at an alarming rate, and it's a warning sign for coastal communities worldwide, new research suggests.
Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Conservation of nature's strongholds needed to halt biodiversity loss
(via sciencedaily.com) Original source To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.
Published Alaska's rusting waters: Pristine rivers and streams turning orange
(via sciencedaily.com) Original source Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Regional differences in bird diversity in agroforestry systems
(via sciencedaily.com) Original source The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published Rabies outbreaks in Costa Rica cattle linked to deforestation
(via sciencedaily.com) Original source Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food
(via sciencedaily.com) Original source A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.
Published The impacts of climate change on food production
(via sciencedaily.com) Original source A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Digging up good news for microbial studies
(via sciencedaily.com) Original source Findings indicate that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com) Original source Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
