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 %.
