Size Dependence of Biomass Spectra and Population Density I. The Effects of Size Scales and Size Intervals

摘要: Abstract Empirical biomass spectra in which is measured logarithmically equal body size intervals are different from those linearly intervals. Moreover, the scales of used by authors may differ, e.g., length, volume, equivalent-sphere diameter and mass. The discrete models derived to explain regularity empirical dependent on choice size-scales size-intervals. Hence, evaluating effect helpful for understanding size-structures ecosystems. In present contribution, we analyse relationships between measures frequently expressing data discuss difference organized On this basis, distribution function spectral density transformation scales. After defining functions density, give an example calculation assuming that allometric relationship. Finally, explore influence validity three developed Kerr, Sheldon co-workers Borgman.
