Joseph Bump, Rolf Peterson and John Vucetich report in the November 2009 issue of the journal Ecology that the carcasses of moose killed by wolves at Isle Royale National Park enrich the soil in "hot spots" of forest fertility around the kills, causing rapid microbial and fungal growth...

Findings advance understanding of how complete food webs function Like the man-eating plant in Little Shop of Horrors, carnivorous plants rely on animal prey for sustenance. Fortunately for humans, carnivorous plants found in nature are not dependent on a diet of human blood but rather are satisfied with the occasional fly or other insect. The existence of carnivorous plants has fascinated botanists and non-botanists alike for centuries and raises the question, "Why are some plants...

The Nutrient-Rich Foods (NRF) Index is a new, objective, science-based way to measure the total nutritional quality of foods and beverages.Effective nutrition profiling should be based on existing science and validated against proven measures of diet quality, according to the August issue of the Journal of Nutrition. A study in the issue outlined the scientific approach taken to develop the NRF Index, a measurement of nutrient density validated against the USDA's scientifically based Healthy...

Most nutrients don't fly solo -- they can interact, join forces or even cancel each other out -- a U.S. health newsletter reports. Two of the key nutrient pairs the Harvard Health Letter writers mention are: -- Vitamin D and calcium. Calcium is easily absorbed, primarily in the small intestine, if large quantities are present but in smaller amounts the mineral gets absorbed with active assistance from vitamin D. Right now, official nutrition guidelines recommend adults get 1,000 mg of calcium...

While proving a long-held theory that suberin blocks water and nutrient absorption in plants, a Purdue University scientist learned more about manipulating the substance to better feed plants. It has long been believed that suberin, a waxy substance between some plant cells, acts as a barrier for the movement of water in a plant's roots. David E. Salt, a professor of plant molecular physiology, discovered a mutant form of the plant Arabidopsis - enhanced suberin 1 or ESB1 - with twice as much...

Manipulating a natural waxy substance found in plants allows for easier absorption of beneficial nutrients, a Purdue University scientist in Indiana said. Botanists have long believed the substance suberin acted as a barrier for the movement of water in plants. David Salt, a plant molecular physiologist, confirmed the theory by testing a mutant form of the plant Arabidopis, which has twice as much suberin as other varieties of that plant, Purdue said in a release Friday. It's been known for...
