model.bso.apply {barrks}R Documentation

Use BSO

Description

This page describes the usage of BSO with phenology(). The model-specific inputs are listed and its basic functionality is explained. BSO was published by Jakoby et al. (2019) and parametrized for Ips typographus in Switzerland. Note that the onset and the development submodel do not support the usage of a storage (except for some precalculations).

Arguments

...

See phenology() for a detailled description of the function.

tmin, tmax

Daily minimum/maximum air temperatures in °C.

sunrise, sunset

Time of sunrise/sunset in minutes from midnight. Can be created with create_suntimes_rsts() or create_suntimes_df().

n

number of individuals to simulate.

max_generations

maximum number of generations to calculate.

Details

In barrks, phenology() is used to apply a model. The following code illustrates which inputs are required to apply BSO and which additional parameters are available.

bso_phenology("bso", ..., tmin, tmax, sunrise, sunset,
              n = 1e+09, max_generations = 4)

# calculate submodels separately
bso_phenology("bso", ..., .submodels = 'onset',
              tmin, tmax, sunrise, sunset, n = 1e+09)
bso_phenology("bso", ..., .submodels = 'diapause', tmin, tmax)
bso_phenology("bso", ..., .submodels = 'development',
              .onset, .diapause = NULL, .mortality = NULL,
              tmin, tmax, sunrise, sunset,
              max_generations = 4)

Value

The function returns a BSO phenology. Look here to find out how it can be analysed.

Functioning of the BSO

In the following, the basic functioning of BSO is explained.

Look here to find out how the model parameters affect the actual calculations and which values are used by default.
