aphid

A modified data set from Table 1 in Satar and Yokomi (2002) on days of
development for Brachycaudus schwartzi across different constant
temperatures and life stages

datasets

There are three different modules: (1) model fitting and selection
using a set of the most commonly used equations describing developmental
responses to temperature helped by already existing R packages ('rTPC')
and nonlinear regression model functions from 'nls.multstart'
(Padfield et al. 2021, <doi:10.1111/2041-210X.13585>), with visualization
of model predictions to guide ecological criteria for model selection;
(2) calculation of suitability thermal limits, which consist on a
temperature interval delimiting the optimal performance zone or suitability;
and (3) climatic data extraction and visualization inspired on previous
research (Taylor et al. 2019, <doi:10.1111/1365-2664.13455>), with either
exportable rasters, static map images or html, interactive maps.
