Soil nutrient availability and reproductive effort drive patterns in nutrient resorption in Pentaclethra macroloba (2013, background): “Mass loss may be 0–10% during senescence (Chapin et al. 1990, Van Heerwaarden et al. 2003).”
Global resorption efficiencies and concentrations of carbon and nutrients in leaves of terrestrial plants (2012, background): “Leaf mass loss could lead to an average NuR underestimation of 10% when using leaf mass-based concentrations, while leaf shrinkage could lead to an average underestimation of 6% when using area-based concentrations (van Heerwaarden et al. 2003a).”
Leaf nutrient concentration, nutrient resorption and litter decomposition in an evergreen broad-leaved forest in eastern China (2007, background): “Therefore, although we acknowledged that leaf nutrient resorption efficiency might be underestimated due to considerable weight loss during senesce, as discussed by Van Heerwaarden et al. (2003), we expressed N (or P) per unit Fig.”
Seasonal nitrogen dynamics of Miscanthus×giganteus and Panicum virgatum (2009, background): “…senescence, the process whereby cellular constituents are systematically broken down and transported out of senescing organs as visually indicated by yellowing and death of green tissue (Lambers et al., 1998), could allow 450% of leaf N to be resorbed by the plant (van Heerwaarden et al., 2003).”
Nutrient resorption of wetland graminoids is related to the type of nutrient limitation (2005, background): “As RE was generally ≥ 80%, possible differences in mass loss between May and July would hardly have affected the results (van Heerwaarden et al. 2003).”
RESORPTION EFFICIENCY DECREASES WITH INCREASING GREEN LEAF NUTRIENTS IN A GLOBAL DATA SET (2005, background): “Area-based measures do not confound target element resorption with changes in leaf mass, but leaf area shrinkage also may occur during senescence and can underestimate resorption efficiency by 10% (van Heerwaarden et al. 2003).”
Dominance of legume trees alters nutrient relations in mixed species forest restoration plantings within seven years (2008, methodology): “Mass-based calculations of proportional resorption of elements are generally underestimations, since besides the nutrient in question, other elements are also retranslocated from senescing leaves into surviving plant parts (van Heerwaarden et al. 2003).”
