Calculating starvation related mortality of Thaumetopoea processionea

Description

Calculating the starvation-related mortality rate of L1 larvae, dependent on degree days from the first hatch to feeding start (bud swelling of the host tree Quercus robur). All already available parameter settings can be shown with parameter().

Usage

mortality(
  x,
  par_budswelling = "quercus_robur_clone256_type1",
  par_hatch = c("custers", "wagenhoff", "meurisse"),
  def_hatch = "first",
  last = TRUE
)

Arguments

x	SpatRaster list (tmean, tmax, tmin) - numeric - with time attribute
par_budswelling	character - parametrisation for bud swelling
par_hatch	character - parametrisation for hatch
def_hatch	definition of hatch - character - either "first" or "mean"
last	If TRUE returns only the result for the last day. last row/layer for data.frame/SpatRaster

Value

SpatRaster with mortality in %.
