Published Migratory birds can partially offset climate change
(via sciencedaily.com) Original source A new study demonstrates that birds can partially compensate for climate change by delaying the start of spring migration and completing the journey faster. But the strategy comes with a cost -- a decline in overall survival.
Published Scientists advocate for integration of biogeography and behavioral ecology to rapidly respond to biodiversity loss
(via sciencedaily.com) Original source An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com) Original source A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published Rooting out how plants control nitrogen use
(via sciencedaily.com) Original source Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.
Published Scientists show how we can anticipate rather than react to extinction in mammals
(via sciencedaily.com) Original source Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.
Published In Florida study, nonnative leaf-litter ants are replacing native ants
(via sciencedaily.com) Original source A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
Published Environmental impact reports hugely underestimate consequences for wildlife
(via sciencedaily.com) Original source Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.
Published Long-forgotten equation provides new tool for converting carbon dioxide
(via sciencedaily.com) Original source To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published Sierra squirrels find their niche amid a changing climate
(via sciencedaily.com) Original source A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.
Published US forests face an unclear future with climate change
(via sciencedaily.com) Original source Climate change might compromise how permanently forests are able to store carbon and keep it out of the air. In a new study, researchers found that the regions most at risk to lose forest carbon through fire, climate stress or insect damage are those regions where many forest carbon offset projects have been set up. The authors assert that there's an urgent need to update these carbon offsets protocols and policies.
Published Shedding light on mechanisms of electrochemical energy storage
(via sciencedaily.com) Original source Researchers have developed a new technique that can quickly identify the exact electrochemical mechanisms taking place in batteries and supercapacitors of various compositions -- a breakthrough that could speed the design of higher performing energy storage devices.
Published Discovery of ferroelectricity in an elementary substance
(via sciencedaily.com) Original source Researchers have discovered a new single-element ferroelectric material that alters the current understanding of conventional ferroelectric materials and has future applications in data storage devices.
Published Gone for good? California's beetle-killed, carbon-storing pine forests may not come back
(via sciencedaily.com) Original source Ponderosa pine forests in the Sierra Nevada that were wiped out by western pine beetles during the 2012-2015 megadrought won't recover to pre-drought densities, reducing an important storehouse for atmospheric carbon.
Published Levies on Renewable Energy Profits could serve as a barrier to achieving Net Zero Targets in the UK
(via sciencedaily.com) Original source Placing levies on the profits made in the renewable energy industry could hinder the UK's ability to meet its 2050 net zero carbon reduction targets, an expert has said.
Published Lifting the veil on disease avoidance strategies in multiple animal species
(via sciencedaily.com) Original source A framework has been developed to test disgust and its associated disease avoidance behaviors across various animal species, social systems, and habitats. Over 30 species have been predicted to exhibit disease avoidance strategies in the wild. With these predictions, the team accounts for models of specific ecological niches, sensory environments and social systems for a number of species including the native common octopus and the invasive red-eared slider, which are both relevant to Japan.
Published New tool shows progress in fighting spread of invasive grass carp in Great Lakes
(via sciencedaily.com) Original source Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.
Published A detailed map of the microverse: Microbial niches
(via sciencedaily.com) Original source What defines the habitat -- the ecological niche -- of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is difficult to predict. A research team has redefined microbial niches by determining which microorganisms live together.
Published Insect decline also occurs in forests
(via sciencedaily.com) Original source The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.
Published Major storage capacity in water-based batteries
(via sciencedaily.com) Original source Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.
Published Warming Arctic draws marine predators northwards
(via sciencedaily.com) Original source Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
