Published Scale matters in determining vulnerability of freshwater fish to climate changes
(via sciencedaily.com) Original source A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
Published Ancient arachnid from coal forests of America stands out for its spiny legs
(via sciencedaily.com) Original source The spiny legged 308-million-year-old arachnid Douglassarachne acanthopoda was discovered the famous Mazon Creek locality.
Published How did sabre-toothed tigers acquire their long upper canine teeth?
(via sciencedaily.com) Original source In a groundbreaking study an international team of scientists has investigated the evolutionary patterns behind the development of sabre teeth, with some unexpected results along the way.
Published Climate change likely to aggravate brain conditions
(via sciencedaily.com) Original source Climate change, and its effects on weather patterns and adverse weather events, is likely to negatively affect the health of people with brain conditions, argue a team of researchers.
Published From roots to resilience: investigating the vital role of microbes in coastal plant health
(via sciencedaily.com) Original source Understanding how salt marsh grass stays healthy is of crucial ecological importance, and studying the ways bacteria interact with these plants is key. Thanks to recent advances in genomic technology, biologists have begun to reveal never-before-seen ecological processes.
Published Access to gardens and citizen science helps encourage conservation among children, study shows
(via sciencedaily.com) Original source Access to gardens and citizen science projects at school can help promote pro-conservation behaviour among pupils, a new study shows.
Published Scientists want to know how the smells of nature benefit our health
(via sciencedaily.com) Original source Spending time in nature is good for us. And knowing more about nature's effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.
Published Bees and butterflies on the decline in western and southern North America
(via sciencedaily.com) Original source Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a new study.
Published Summers warm up faster than winters, fossil shells from Antwerp show
(via sciencedaily.com) Original source In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.
Published Climate change is most prominent threat to pollinators
(via sciencedaily.com) Original source A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
Published First 'warm-blooded' dinosaurs may have emerged 180 million years ago
(via sciencedaily.com) Original source The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago. The new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic Era (the dinosaur era lasting from 230 to 66 million years ago), drawing on 1,000 fossils, climate models and the geography of the period, and dinosaurs' evolutionary trees.
Published 90% of Floridians believe climate change is happening
(via sciencedaily.com) Original source The latest 'Florida Climate Resilience Survey' found that 90% of Floridians believe that climate change is happening. Belief in human-caused climate change has surged among Florida Independents while slipping among Republicans in the state since last fall. But despite these changes, the survey found enduring support among Floridians for increased government action to address the consequences of a warming planet. The survey found 68% of all respondents want state government to do more and 69% want the federal government to do more to address climate change.
Published How wildfires change soil chemistry
(via sciencedaily.com) Original source Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
Published 2023 was the hottest summer in two thousand years
(via sciencedaily.com) Original source Researchers have found that 2023 was the hottest summer in the Northern Hemisphere in the past two thousand years, almost four degrees warmer than the coldest summer during the same period.
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 Scientists unlock key to breeding 'carbon gobbling' plants with a major appetite
(via sciencedaily.com) Original source The discovery of how a critical enzyme 'hidden in nature's blueprint' works sheds new light on how cells control key processes in carbon fixation, a process fundamental for life on Earth. The discovery could help engineer climate resilient crops capable of sucking carbon dioxide from the atmosphere more efficiently, helping to produce more food in the process.
Published New light shed on carboxysomes in key discovery that could boost photosynthesis
(via sciencedaily.com) Original source A research team has discovered how carboxysomes, carbon-fixing structures found in some bacteria and algae, work. The breakthrough could help scientists redesign and repurpose the structures to enable plants to convert sunlight into more energy, paving the way for improved photosynthesis efficiency, potentially increasing the global food supply and mitigating global warming.
Published Ocean biodiversity work needs improvement
(via sciencedaily.com) Original source An international collaboration says the world's largest marine protected areas aren't collectively delivering the biodiversity benefits they could be because of slow implementation of management strategies and a failure to restrict the most impactful human activities.
Published Take cover! Survey shows tornado warnings widely misunderstood
(via sciencedaily.com) Original source A study showed that about half of those surveyed in the mid-South could not accurately identify a tornado warning.
Published Improved wildfire smoke model identifies areas for public health intervention
(via sciencedaily.com) Original source The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.
