model.rity.apply

This page describes the usage of RITY with <code>phenology()</code>.
The model specific inputs are listed and its basic functionality is explained.
RITY (also called RITY-2) was published by Ogris2019;textualbarrks and
parametrized for Ips typographus in Slovenia.

Calculate the bark beetle phenology based on raster data or
point-related data. There are multiple models implemented for two bark
beetle species. The models can be customized and their submodels (onset of
infestation, beetle development, diapause initiation, mortality) can be
combined. The following models are available in the package:
PHENIPS-Clim (first-time release in this package),
PHENIPS (Baier et al. 2007) <doi:10.1016/j.foreco.2007.05.020>,
RITY (Ogris et al. 2019) <doi:10.1016/j.ecolmodel.2019.108775>,
CHAPY (Ogris et al. 2020) <doi:10.1016/j.ecolmodel.2020.109137>,
BSO (Jakoby et al. 2019) <doi:10.1111/gcb.14766>,
Lange et al. (2008) <doi:10.1007/978-3-540-85081-6_32>,
Jönsson et al. (2011) <doi:10.1007/s10584-011-0038-4>.
The package may be expanded by models for other bark beetle species in the
future.

Calculate Bark Beetle Phenology Using Different Models

model.rity.apply function

<dl><dt>tmin, tmean, tmax</dt>
<dd>Daily minimum/mean/maximum temperatures in °C.
For the <code>development</code> submodel, the parameter that is obligatory depends on
<code>mode</code>.</dd>
<dt>daylength</dt>
<dd>Length of the day in hours. Can be created with
<code>create_daylength_rst()</code> or <code>create_daylength_rst()</code>.</dd>
<dt>mode</dt>
<dd>Specifies which temperature should be used to calculate the
development. Can be <code>min</code>, <code>mean</code> or <code>max</code>.</dd>
<dt>.submodels, .onset, .diapause, .mortality, ...</dt>
<dd>See <code>phenology()</code> for a detailled description of the function.</dd></dl>

Arguments

In the following, the basic functioning of RITY is explained.<ul>
<li>Onset: See PHENIPS.</li>
<li>Development: Based on PHENIPS with a few modifications:<ul>
<li>The optimum curve is calculated according to
Wermelinger1998;textualbarrks without
simplification.</li>
<li>The minimum, mean or maximum bark temperature can be used to calculate
the development. These temperatures depend only on the respective air temperatures.</li>
</ul></li>
<li>Diapause: See PHENIPS.</li>
<li>Mortality: See PHENIPS.</li>
</ul>Look here to find out how the model parameters affect the actual calculations and which values are used by default.
