model.rity.apply {barrks} | R Documentation |
Use RITY
Description
This page describes the usage of RITY with phenology()
.
The model specific inputs are listed and its basic functionality is explained.
RITY (also called RITY-2) was published by Ogris et al. (2019) and
parametrized for Ips typographus in Slovenia.
Arguments
tmin , tmean , tmax |
Daily minimum/mean/maximum temperatures in °C.
For the |
daylength |
Length of the day in hours. Can be created with
|
mode |
Specifies which temperature should be used to calculate the
development. Can be |
.submodels , .onset , .diapause , .mortality , ... |
See |
Details
In barrks
, phenology()
is used to apply a model. The following code
illustrates which inputs are required to apply RITY and which additional
parameters are available.
phenology("rity", ..., tmin = NULL, tmean = NULL, tmax, daylength, mode = 'max') # calculate submodels separately phenology("rity", ..., .submodels = 'onset', tmax) phenology("rity", ..., .submodels = 'diapause', daylength) phenology("rity", ..., .submodels = 'mortality', tmax) phenology("rity", ..., .submodels = 'development', .onset, .diapause = NULL, .mortality = NULL, tmin = NULL, tmean = NULL, tmax = NULL, mode = 'max')
Value
The function returns a phenology. Look here to find out how it can be analysed.
Functioning
In the following, the basic functioning of RITY is explained.
-
Onset: See PHENIPS.
-
Development: Based on PHENIPS with a few modifications:
The optimum curve is calculated according to Wermelinger and Seifert (1998) without simplification.
The minimum, mean or maximum bark temperature can be used to calculate the development. These temperatures depend only on the respective air temperatures.
-
Diapause: See PHENIPS.
-
Mortality: See PHENIPS.
Look here to find out how the model parameters affect the actual calculations and which values are used by default.
