Pseudobulbs: sink for exogenous nitrogen in epiphytic orchids
Pseudobulbs, which are somewhat enlarged or thickened succulent stems, are common in epiphytic orchids. Nitrogen can be transported from old to young pseudobulbs and between leaves and pseudobulbs......»»
Electrochemical flow aziridination of terpenes
Due to the inherent physiological properties of nitrogen-containing heterocyclic moieties, the construction of nitrogen-containing compounds has emerged as one of the central issues in contemporary synthetic chemistry over recent decades. Among these.....»»
New photoreactor technology could pave the way to a carbon-neutral future, researchers say
An international team that includes researchers from the University of Toronto has designed and implemented a new model for photoreactors, a solar-powered technology for converting water, carbon dioxide, methane and nitrogen into greener chemicals an.....»»
Climate protection: Land use changes cause the carbon sink to decline
Forests can bind large amounts of carbon on the land surface. In this way, they decisively contribute to reducing net greenhouse gas emissions. For some areas, however, data are still lacking. In Eastern Europe, in particular, the network of installe.....»»
Nitrogen runoff strategies complicated by climate change
As climate change progresses, rising temperatures may impact nitrogen runoff from land to lakes and streams more than projected increases in total and extreme precipitation for most of the continental United States, according to new research from a t.....»»
Long-term study finds nitrogen fixation hot spots in Atlantic seaweed
A new study by researchers at the University of North Carolina at Chapel Hill examined nitrogen fixation among diazotrophs—microorganisms that can convert nitrogen into usable form for other plants and animals—living among sargassum. Sargassum, a.....»»
New way of measuring ocean carbon could better align with climate policy goals
The ocean controls our climate. It is the largest carbon sink on the planet, absorbing 40% of human fossil fuel emissions and almost all the excess heat generated by global warming......»»
Study improves understanding of how bacteria benefit plant growth
Plants form alliances with microbes in the soil in which they grow. Legumes, for example, benefit from a symbiotic relationship with microbes that inhabit nodules in their roots and "fix" nitrogen in the atmosphere to make it available to promote the.....»»
Supporting increased crop growth by regulating the expression of genes that support nitrogen fixation
An article describing research conducted by John Peters, Ph.D., chair of the Department of Chemistry and Biochemistry, Dodge Family College of Arts and Sciences at the University of Oklahoma, and fellow researchers, has been published in the journal.....»»
Good for soil, grim for the air: More than third of fertilizer use breaking UK Government emissions thresholds
Some nitrogen fertilizer types spread on UK farmland are ending up in the atmosphere, with the worst offenders emitting on average 18% of the applied nitrogen fertilizer as ammonia gas into the air......»»
Net diversification rate mainly drives species richness disparity in tropical terrestrial orchids
Species richness is not only spatially heterogeneous along latitudes, but also among hyperdiverse tropical floras. However, few studies have elucidated the patterns of species richness in tropical terrestrial orchids......»»
It"s sewage, not fertilizer fueling nitrogen surge in Florida"s Indian River Lagoon
From recurring harmful algal blooms—including brown tides—to catastrophic seagrass losses, fish kills and unusual marine mammal deaths—including the threatened Florida manatee—the Indian River Lagoon is environmentally distressed. For decades.....»»
AT&T stock fell to 29-year low on Friday and sank another 6.7% today
AT&T, Verizon, Frontier, and Lumen all get hammered after lead-cable reports. Enlarge (credit: Getty Images | Eugene Mymrin) AT&T's stock price hit a 29-year low on Friday and continued to sink today as investors fled te.....»»
Global database of data for almost 3,000 orchid species show diversity of pollination strategies
Recent research, published in the Botanical Journal of the Linnean Society, used the database to reveal that orchids show remarkable diversity of highly specialized pollination strategies that differ across global regions......»»
Global cooling caused diversity of species in orchids, confirms study
Research led by the Milner Center for Evolution at the University of Bath looking at the evolution of terrestrial orchid species has found that global cooling of the climate appears to be the major driving factor in their diversity. The results help.....»»
Scientists reveal molecular interaction of carbon/nitrogen metabolism in rice
Carbon and nitrogen are the two most abundant nutrients for all living organisms. The metabolism of carbon and nitrogen is tightly coupled and coordinated by different metabolites and signaling pathways. What are the molecular mechanisms that sense a.....»»
Hexagonal MBene: A promising platform for the electrocatalytic nitrogen reduction reaction
A Chinese team has published new work in Energy Material Advances......»»
Top corn producing state to see future drop in yield, cover crop efficiency: Study
Winter cover crops could cut nitrogen pollution in Illinois' agricultural drainage water up to 30%, according to recent research from the University of Illinois Urbana-Champaign. But how will future climate change affect nitrogen loss, and will cover.....»»
Study shows floating plants best at purifying wastewater
According to research by Lisanne Hendriks, an ecologist at Radboud University, azolla and duckweed are the best floating aquatic plants for purifying wastewater. The plants absorb nitrogen and phosphorus from wastewater and so render it much cleaner......»»
New study quantifies temperature sensitivity of soil gaseous nitrogen loss in forest ecosystems
Researchers from the Institute of Applied Ecology and the Institute of Geographical Sciences and Natural Resources Research of the Chinese Academy of Sciences have investigated the critical role of gaseous nitrogen loss (N2O and N2) in nitrogen limit.....»»
Deforestation in Brazilian Amazon caused emission of 90 million metric tons of CO2 in 2013–21, reports study
Deforestation in Indigenous Territories (ITs) in the Brazilian Amazon caused the emission of 96 million metric tons of carbon dioxide (CO2) between 2013 and 2021, modifying the forest's role as a carbon sink in these areas. Emissions in the last thre.....»»
