Published More Texas owls are testing positive for rat poisons
(via sciencedaily.com) New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.
Published Freshwater connectivity can transport environmental DNA through the landscape
(via sciencedaily.com) A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published Largest historic fire death toll belongs to aftermath of 1923 Japan Earthquake
(via sciencedaily.com) Original source Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kant earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history -- comparable to the number of people killed in the World War II atomic bombing of Hiroshima. The story of the conflagration, not well-known outside of Japan, holds important lessons for earthquake scientists, emergency response teams and city planners, according to a new article.
Published Plant-based food alternatives could support a shift to global sustainability
(via sciencedaily.com) Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.
Published New super-fast flood model has potentially life-saving benefits
(via sciencedaily.com) Researchers have developed a new simulation model, which can predict flooding during an ongoing disaster more quickly and accurately than currently possible.
Published Climate change is reducing global river water quality
(via sciencedaily.com) Original source A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.
Published Fewer but more intense tropical storms predicted over the Ganges and Mekong
(via sciencedaily.com) Original source Climate experts project a decline in the frequency of future tropical storms but an increase in their strength across the Ganges and Mekong basins allowing for better future planning.
Published Fall snow levels can predict a season's total snowpack in some western states
(via sciencedaily.com) Original source Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.
Published Hot summer air turns into drinking water with new gel device
(via sciencedaily.com) Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
Published Studies highlight new approaches to addressing climate change
(via sciencedaily.com) Original source Failing to achieve climate mitigation goals puts increasing pressure on climate adaptation strategies. In two new studies, researchers address novel approaches to these issues.
Published Lions on the brink -- New analysis reveals the differing threats to African lion populations
(via sciencedaily.com) Original source New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.
Published Study reveals human destruction of global floodplains
(via sciencedaily.com) Original source A hydrologist's study provides a global estimate of human destruction of natural floodplains. The study can help guide future development in a way that can restore and conserve vital floodplain habitats that are critical to wildlife, water quality and reducing flood risk for people.
Published Bees struggle to find flowers because of air pollution
(via sciencedaily.com) Original source A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent.
Published Artificial intelligence could help build pollen jigsaw of present and ancient flora
(via sciencedaily.com) Original source An emerging system which combines rapid imaging with artificial intelligence could help scientists build a comprehensive picture of present and historic environmental change -- by swiftly and accurately analyzing pollen.
Published Invasive alien species play key role in 60% of global plant and animal extinctions
(via sciencedaily.com) A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published Lack of evidence hampers progress on corporate-led ecosystem restoration
(via sciencedaily.com) An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.
Published Echoes of extinctions: Novel method unearths disruptions in mammal trait-environment relationships
(via sciencedaily.com) Original source New research explores the historical shifts in mammal traits and biodiversity loss in eastern Africa. The study reveals how environmental changes disrupted mammal communities and highlights the urgent need for targeted conservation efforts to protect vulnerable species.
Published New research highlights opportunities to protect carbon and communities from forest fires
(via sciencedaily.com) Original source As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.
Published Balancing biodiversity, climate change, food for a trifecta
(via sciencedaily.com) Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.
Published Invasive species are animals, too: Considering a humane approach
(via sciencedaily.com) Invasive alien species are animals that may pose a threat to biodiversity, but it's time to deal with that threat in a more ethical way.
