New research from the National University of Singapore showed that between 1996 and 2016, substantial mangrove forests have been converted to agricultural use in Myanmar.
In a study, the researchers used a machine learning algorithm to classify more than 110 types of plastics, including commercial and lab-made varieties, to better understand how they might degrade in the ocean.
DOE laboratories are collaborating on a new high-resolution Earth systems model to predict climate trends into the next century. The model will provide the scientific basis by which to mitigate the effects of extreme climate on energy and other essential services.
Habitat loss for imperiled species in the U.S. was found to be more than twice as great on non-protected private lands than on federally protected lands. The study shows that federal land protection and endangered species listings are effective tools for stemming losses in species habitat.
A new study shows irrigation of cattle feed crops is the greatest consumer of river water in the Western United States, implicating beef and dairy consumption as the leading driver of water shortages and fish imperilment in the region.
New York University biologists captured highly transient interactions between transcription factors—proteins that control gene expression—and target genes in the genome and showed that these typically missed interactions have important practical implications. In a new study published in Nature Communications, the researchers developed a method to capture transient interactions of NLP7, a master transcription factor involved in nitrogen use in plants, revealing that the majority of a plant’s response to nitrogen is controlled by these short-lived regulatory interactions.
Protecting the permafrost after a record fire season
A new study shows for the first time how massive flood events in the eastern North Pacific Ocean—known as the Missoula Floods—may have in part triggered abrupt climate changes in the Northern Hemisphere during the last deglaciation (approximately 19,000–11,700 years ago). The findings are contrary to the long held notion that cooling was primarily driven by changes in North Atlantic circulation.
The study, led by the University of York, found evidence for a period of enhanced pre-industrial sea-level rise of about two to three millimetres per year in three locations: Nova Scotia, Maine and Connecticut.
Methane is a gas that deserves more attention in the climate debate as it contributes to almost half of human-made global warming in the short-term.
In the first major study following the devastating 2014 Carlton Complex fire in north central Washington, researchers from the University of Washington and U.S. Forest Service found that previous tree thinning and prescribed burns helped forests survive the fire.
Inland Antarctic ice contains volumes of water that can raise global sea levels by several metres. A new study published in the journal Nature shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.
The American chestnut tree was made functionally extinct by an invasive blight fungus in the early 1900s. Work is currently underway to develop a blight-resistant variety through breeding and genetic engineering. With the potential reintroduction of American chestnut in the Eastern United States, SUNY Geneseo assistant professor of geography Stephen Tulowiecki, mapped the historical location of chestnut using land surveyors from 1797–1799. His research appears in the journal Forest Ecology and Management.
Floridians from all major political parties believe climate change is real and are concerned about its impact on future generations in the state, according to the second Florida Climate Resilience Survey.
Female sea turtles mate multiply to ensure fertilization. A study of nesting loggerhead female sea turtles in southwestern Florida used genotyping to uncover how many fathers were represented in their nests. Surprisingly, scientists found that 75 percent of the female sea turtles had mated singly. No male was represented in more than one female’s clutches. Findings provide insights into the relative numbers of males present in the breeding population, which are hard to get because males never come ashore.
Applying deep learning to seismic data has revealed tremor and slip occur at all times—before and after known large-scale slow-slip earthquakes—rather than intermittently in discrete bursts, as previously believed.
New research on sand dunes in China describes how even neighboring dunes can long remain in different and seemingly conflicting states — confounding the assessment of stabilization efforts and masking the effects of climate change.
A new study published in the African Journal of Ecology considers the role of the moon in driving a particularly rare occurrence: the solo journey of a naked mole rat from one underground colony to start a new one.
