Allometric power laws in NZ mountain beech forests

Using above-ground biomass to measure the biomass of individual trees, we tested three power laws (Taylor's law; density-mass allometry; and variance-mass allometry) using 10 censuses of New Zealand mountain beech trees in 250 plots over 30 years on spatial scales ranging from 5 m to kilometers.

The data support an article in Oikos : "Taylor's law and related allometric power laws in New Zealand mountain beech forests: the roles of space, time, and the environment" by Joel E. Cohen, Jiangshan Lai, David A. Coomes, and Robert B. Allen. 2016. (http://dx.doi.org/10.1111/oik.02622)
