Photo: Device measuring outgassing of nitrogen from desert soil (Cornell University) You may have heard of nitrogen being lost through processes such as soil erosion , but according to a new study from Cornell University, warming climates are also causing soils to lose nitrogen as a gas. Arid soils are particularly affected - and with nitrogen being one of the key nutrients for plant growth, the study...

By Krishna Ramanujan Ithaca NY (SPX) Nov 10, 2009 - As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers. As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study.

Wheeler Crest Eastern Sierra wallpaper Nitrogen loss threatens desert plant life, study shows Sparks (associate professor of ecology and evolutionary biology) and lead author Carmody McCalley, a graduate student, warn that temperature increases and shifting precipitation patterns due to climate change may lead to further nitrogen losses in arid ecosystems. That would make arid soils even more [...]...

by Gina Misiroglu This book is chock full of questions kids might ask and simple short answers to those questions. Let me share an example: How much air does a person breathe in a lifetime? During a person's ife, he or she will breathe about 75 million gallons (284 liters) of air. Every minute, the human body need 2 gallons (7.5 liters) of air when lying down, 4 gallons when sitting, 6 gallons when...

Africanized killer bees may be less of a problem for native bees than weather changes, scientists in Panama say. The aggressive bees have spread northward after accidentally being released in Brazil in 1957, prompting fears they would compete with native bees, said David Roubik, a staff scientist at the Smithsonian Tropical Research Institute in Panama City. A 17-year study of the aggressive bees'...

NASA : Researchers have conducted the first global analysis of the health and productivity of ocean plants, as revealed by a unique signal detected by a NASA satellite. Ocean scientists can now remotely measure the amount of fluorescent red light emitted by ocean phytoplankton and assess how efficiently the microscopic plants are turning sunlight and nutrients into food through photosynthesis. They...

Preserved plants don’t look much like their living counterparts after they are flattened and dried. The Harvard Museum of Natural History instead has displays of plants made of glass! Leopold Blaschka and his son Rudolf came from a long line of talented glassmakers. As a hobby, Leopold began making glass flowers from illustrations in natural [...]
