Calculating biomass production and loss from repeated censuses

Description

Code provided in SI of Koyhama et al. 2019 for estimating biomass gains and losses. Used by SummaryAGWP_Kohyama wrapper.

Usage

turnover(
  x1,
  x2,
  xs1,
  intvl,
  area,
  subpop = NULL,
  simple = FALSE,
  annual = FALSE
)

Arguments

x1	Numeric vector. Biomass of stems in first census (Mg)
x2	Numeric vector. Biomass of stems in second census (Mg)
xs1	Numeric vector. Initial biomass of stems that survived from first census to second census (Mg)
intvl	Numeric. Census interval length (years).
area	Numeric. Plot area (ha)
subpop	Vector giving subpopulation membership of each stem
simple	Logical. Only used to obtain the different outputs from Koyhama et al.
annual	Logical. Only used to obtain the different outputs from Koyhama et al.
