model.bso.customize | R Documentation |
This page describes the parameters that can be used to customize BSO. The model was developed by \insertCiteJakoby2019;textualbarrks. Look here to find out how to apply the model.
dd_onset_start_date |
The date, when the degree days start to sum up ('MM-DD'). |
dd_onset_base |
Base temperature to calculate degree days to trigger the onset. |
dd_onset_threshold |
Degree days that are required before the individuals
start regeneration feeding in |
slot_dia |
Maturation feeding slot where the individuals start regeneration feeding after diapause. |
k |
Factor for the calculation of the phloem temperature. |
alpha , tlo , tup |
Parameters used to calculate the transition probabilities for each stage (except preflight) in the following order: development, maturation feeding, reproduction. |
tfly_min , tfly_max , pfly_max , beta |
Parameters used to calculate the transition probabilities for the preflight stage. |
num_slots |
Named vector that defines the number of slots for each stage.
The development stage is subdivided into the stages |
psis |
Probability that a sister brood will be established. |
slot_sis |
Maturation feeding slot where the individuals start regeneration feeding before they establish a sister brood. |
model_end_date |
Date when the model ends (no further development will be modeled). |
diapause_first |
The day of year when the diapause could start at the earliest. |
diapause_last |
The day of year when the diapause could start at the latest. |
tdia_min |
The diapause will be initiated when the average daily temperature falls below that value. |
In barrks
, model()
is used to customize a model. The following code
illustrates which parameters are available for BSO and specifies their
default values.
