Published Study revisits Texas seismic activity occurring before 2017, confirming connection to wastewater injection
(via sciencedaily.com) Original source A new study by seismologists reexamines earthquakes in the Permian Basin that occurred before 2017 against the real-time data collected from earthquakes taking place after 2020. Results confirm that the seismicity occurring from 2009-2017 was causally linked to the underground injection of wastewater that is a byproduct of oil and gas extraction.
Published Catching a new (sea) star
(via sciencedaily.com) Original source Researchers have discovered a new species of sea star (also known as starfish). The discovery came about thanks to collaborative work among researchers, fishers, and aquarium and museum staff. The starfish, which has been named Paragonaster hoeimaruae, belongs to the family Pseudarchasteridae. It is a distinctive red and beige color, with five arms and spans just over 10 centimeters.
Published Seismic detectors measure soil moisture using traffic noise
(via sciencedaily.com) Original source Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
Published New model refutes leading theory on how Earth's continents formed
(via sciencedaily.com) Original source Computational modeling shows that plate tectonics weren't necessary for early continents.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species
(via sciencedaily.com) Original source A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Towards smart cities: Predicting soil liquefaction risk using artificial intelligence
(via sciencedaily.com) Original source Soil liquefaction that results in infrastructure damage has long been a point of contention for urban planners and engineers. Accurately predicting the soil liquefaction risk of a region could help overcome this challenge. Accordingly, researchers applied artificial intelligence to generate soil liquefaction risk maps, superseding already published risk maps.
Published Cash and conservation: A worldwide analysis of wildlife represented on money
(via sciencedaily.com) Original source Researchers investigate the representation of native fauna on 4,541 banknotes from 207 countries between 1980 and 2017, to identify geographic hotspots and taxonomic patterns, and determine whether threatened and endemic species were more readily represented.
Published Monarch butterflies need help, and a little bit of milkweed goes a long way
(via sciencedaily.com) Original source Researchers and community scientists monitored urban milkweed plants for butterfly eggs to learn what makes these city gardens more hospitable to monarchs. They found that even tiny city gardens attracted monarchs and became a home to caterpillars.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published Two shark species documented in Puget Sound for first time
(via sciencedaily.com) Original source Researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered.
Published Climate is most important factor in where mammals choose to live, study finds
(via sciencedaily.com) Original source Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.
Published New Zealand's flightless birds are retreating to moa refuges
(via sciencedaily.com) Original source Researchers have found New Zealand's endangered flightless birds are seeking refuge in the locations where six species of moa last lived before going extinct.
Published Human-infecting parasite produces sterile soldiers like ants and termites
(via sciencedaily.com) Original source New research finds a tiny freshwater parasite known to cause health problems in humans defends its colonies with a class of soldiers that cannot reproduce. The discovery vaults this species of parasitic flatworm into the ranks of complex animal societies such as ants, bees and termites, which also have distinct classes of workers and soldiers that have given up reproduction to serve their colony.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
Published Tropical plant species are as threatened by climate change as widely feared, study confirms
(via sciencedaily.com) Original source Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.
Published Genome study informs restoration of American chestnut tree
(via sciencedaily.com) Original source Researchers use genomes to help restore the American chestnut population and adjust species breeding to the changing climate.
Published Discovery of a hybrid lineage offers clues to how trees adapt to climate change
(via sciencedaily.com) Original source The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.
Published Forests endure as carbon sink despite regional pressures
(via sciencedaily.com) Original source Despite facing regional threats like deforestation and wildfires, the world's forests continue to be a powerful weapon in the fight against climate change. A new study reveals these vital ecosystems have consistently absorbed carbon dioxide for the past three decades, even as disruptions chip away at their capacity. The study, based on long-term ground measurements combined with remote sensing data, found that forests take up an average of 3.5 0.4 billion metric tons of carbon per year, which is nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019.
Published Logged forests can still have ecological value -- if not pushed too far
(via sciencedaily.com) Original source Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
Published Scientists use machine learning to predict diversity of tree species in forests
(via sciencedaily.com) Original source Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.
