#' Germination rates of \emph{Abutilon angulatum} at different temperatures
#'
#' Germination rates of \emph{Abutilon angulatum} from 29 different studies, undertaken
#' at different ambient temperatures. We would like to know how germination rate
#' varies with temperature, in particular, the range of temperatures at which \emph{Abutilon angulatum} 
#' will germinate. These data come from a larger study across species and environments
#' to look for a latitudinal signal in tolerance to changing temperature (Sentinella et al 2020).
