...eletal integrity." Skeletal integrity in hens also decreases during management practices used to improve shell quality and lengthen a bird's production life, Hester said. Previous studies by other researchers have found that osteoporosis accounts for 15 percent to 30 percent of total fatalities in hens.

...the concentration of oxygen in the containment bag decreases quickly, while the rate of oxygen consumption by the fish (its metabolic rate) rises. Whenever fish are removed from water, the structures in the gills that exchange gases the lamella will also collapse, which inhibits the uptake of oxygen.

Using data from a similar survey released by the Pew Initiative in March 2001 for tracking purposes, the survey released today suggests: Americans knowledge about GM foods remains low even as...Prescribed burns can threaten pine Savannah amphibians
...the current burn cycle of every two-to-three years decreases the number of amphibian species per pond by about half. "A prescribed burn cycle approaching five years should balance the conflicting needs of amphibians and longleaf pines without placing the entire community in danger of catastrophic fire," say J...New research technique provides unique glimpse into Alzheimer's disease
