A recent study found that adding natural mycorrhizal fungi to synthetic fertilizers can significantly improve plant growth while reducing pesticide use and water consumption. Researchers at Texas A&M AgriLife Communications discovered this inexpensive additive makes better use of fertilizers, saving money and improving the environment.
Researchers found that partial defoliation stimulates micro-organisms to release more nitrogen in the soil. This increase in nitrogen availability allows certain trees to grow larger leaves and recover from initial damage.
Researchers discovered how day length and light quality affect stability of floral-promoting protein constans in Arabidopsis thaliana. This finding helps explain seasonal, day-length dependent flowering behavior in many plant species.
A comprehensive NASA study found that climatic changes have led to increased plant growth globally over the last two decades. The research, published in Science magazine, attributes the increases primarily to climate change, with lesser contributions from carbon dioxide fertilization and forest regrowth.
A more realistic extinction scenario shows that rare and uncommon plant species removal doesn't impact aboveground plant growth, but instead affects remaining rare species. Dominant species impart resistance to ecosystem change even in the face of a 3-fold decline in species.
Researchers at Stanford University conducted a three-year experiment, raising questions about the impact of elevated CO2 on plant growth. The study found that CO2 suppression was most pronounced when combined with other climate change factors like temperature, precipitation, and nitrogen deposition.
Researchers found that large volcanic eruptions, like the 1991 Pinatubo eruption, can temporarily cool the Earth and reduce plant growth due to increased aerosols in the atmosphere. This 'greener greenhouse' effect is partly caused by reduced sunlight and carbon dioxide emissions.
A new NASA study suggests that changes in rainfall patterns play a significant role in plant growth and carbon absorption in the United States. The research found that higher humidity combined with increased precipitation led to a 14% increase in plant growth between 1950 and 1993.
Research teams have discovered oxygen decreases of 10-15% in the upper thermocline, a layer 100-600 meters deep. Slower ocean circulation and increased plant productivity may be contributing factors, potentially linked to climate shifts and global warming.
The Southern African Regional Science Initiative (SAFARI 2000) study investigated coupled land-atmosphere processes associated with aerosols and trace gases. Key findings show the impact of southern African emissions on climate, as visualized through satellite, airborne, and ground-based observations.
Scientists have discovered that a complex carbohydrate, RG-II, plays a crucial role in regulating plant growth by forming a network in the cell wall matrix through boron cross-links. The ability of RG-II to cross-link with boron enables normal plant expansion and prevents dwarfing in mutants without sufficient boron or fucose.
A recent study published in Science found that tallgrass prairies have more variable plant growth than deserts, despite having less rainfall variability. This suggests that these ecosystems can respond to changes in precipitation patterns and may serve as an early warning system for climate change.
A Yale study reveals that plants adjust their growth patterns to optimize photosynthesis based on light intensity, direction, and wavelength. This breakthrough could lead to more resilient crops in less favorable light conditions.
A computer model developed by Dr. Ron Neilson simulates vegetation type in the US and predicts significant changes under global warming scenarios. Simulations show mixed conifers and hardwoods moving north, while desert species shift eastward, leading to increased fire risk and altered water resources.
A Florida biologist found that subtle increases in CO2 can kill mining moths by reducing the nutritional value of their food. Many more larvae died in chambers with high CO2 levels, likely due to malnutrition caused by lower nitrogen content.
