Optimal nutritional status is imperative for growth, development, immune function, and bone health. Patients with thalassemia are known to have poor growth, altered puberty, and immune function as well as reduced bone mineral acquisition. The etiology of these comorbidites is typically ascribed to the toxic effects of transfusion-related iron-overload. Recently, our group and others have observ...

Despite suggestions that animal pollinators are crucial for human nutritional health, no studies have actually tested this claim. Here, we combined data on crop pollination requirements, food nutrient densities, and actual human diets to predict the effects of pollinator losses on the risk of nutrient deficiency. In four developing countries and across five nutrients, we found that 0 to 56% of ...

Increasing the inputs of nutrients has played a major role in increasing the supply of food to a continually growing world population. However, focusing attention on the most important nutrients, such as nitrogen (N), has in some cases led to nutrient imbalances, some excess applications especially of N, inefficient use and large losses to the environment with impacts on air and water quality, ...

Six crossbred lambs (32+/-2 kg) in a 6 x 6 Latin square design were used to determine the effects of predeprivation diet nutrient density and NaCl content on nutrient losses during periods of feed and water deprivation and nutrient repletion. Treatments consisted of two predeprivation dietary nutrient densities (low [LOW] and moderate [MOD]) and three NaCI intakes (0, 2, or 4 g/d) in a 2 x 3 fa...

Animal manures are a valuable resource, providing readily available plant nutrients ; however, runoff from lands receiving animal manure has been shown to contribute to water pollution. Understanding the loss of nutrients from slow release fertilizers, such as animal manure, after application is critical in determining and designing practices to reduce and/or control the temporal availability a...

Biogeochemical cycles are cornerstones of biological evolution. Mature terrestrial ecosystems efficiently trap nutrients and certain ones are largely recycled internally. Preserving natural fluxes of nutrients is an important mission of protected areas, but artificially leaky systems remain common. Native red deer (Cervus elaphus) in the Swiss National Park (SNP) are known to reduce phosphorus ...

Suspended sediment resulted from distributed soil erosions facilitates nutrient transportation and influences soil depletion. Phosphorus (P) is one of the major limiting nutrients controlling eutrophication of surface water. Irregular P load pulsed by heavy rainfall may damage the ecological quality of downstream waters. P transport study during rainfall events is important in both predicting a...

Long-term phosphorus (P) accumulation in agricultural soils presents a challenge for water quality improvement. P is commonly elevated managed intensive livestock production due to repeated overapplication of slurry and fertilisers. High legacy nutrient accumulations result poor via transport pathways such as surface runoff, subsurface drainage, soil erosion. To achieve environmental targets, i...

To investigate the underlying mechanisms that control long-term recovery of tundra carbon (C) and nutrients after fire, we employed the Multiple Element Limitation (MEL) model to simulate 200-yr post-fire changes in the biogeochemistry of three sites along a burn severity gradient in response to increases in air temperature, CO2 concentration, nitrogen (N) deposition, and phosphorus (P) weather...
