Nutrient Addition Dramatically Accelerates Microbial Community Succession
The ecological mechanisms driving community succession are widely debated, particularly for microorganisms. While successional soil microbial communities are known to undergo predictable changes in structure concomitant with shifts in a variety of edaphic properties, the causal mechanisms underlying these patterns are poorly understood. Thus, to specifically isolate how nutrients--important dri...
متن کاملNutrient balance and body composition.
The prevalence of obesity in industrialized countries is increasing in spite of decreased energy and fat intakes. This trend might be mainly a consequence of a decline in energy expenditure. It is suggested here that it might also be accounted for by the increasing proportion of protein in the diet, affecting the hormonal status. The nutrient imbalance is particularly apparent in early childhoo...
متن کاملUrban nutrient balance for Bangkok
To explore the options for recycling of nutrients from mega-cities to agricultural land, a nutrient balance model was developed. The balancing was done for Bangkok Province and considered nitrogen (N) and phosphorus (P). To estimate the food supply, the most decisive nutrient flow, an online database (FAOSTAT) was employed; its country level data are disaggregated to the urban level. A simple a...
متن کاملEcosystem Succession and Nutrient Retention: Vitousek and Reiners' Hypothesis
What mechanisms mediate the flow of energy and cycling of nutrients during ecological succession? Are they linked in time and across space? In 1969, Eugene P. Odum proposed a series of hypotheses that caused the ecological community to think critically about patterns and processes (sensu Watt 1947) during ecological succession and how they might be linked in a causal manner. Odum’s perspective ...
متن کاملDietary Restriction and Nutrient Balance in Aging
Dietary regimens that favour reduced calorie intake delay aging and age-associated diseases. New evidences revealed that nutritional balance of dietary components without food restriction increases lifespan. Particular nutrients as several nitrogen sources, proteins, amino acid, and ammonium are implicated in life and healthspan regulation in different model organisms from yeast to mammals. Agi...
