\usage{
ReptTraits
}
\description{
A processed subset of the ReptTraits database containing 12 quantitative
traits and environmental attributes for 12,060 extant reptile species.
The dataset contains one record per species.
}
\details{
The source ReptTraits database contains 40 variables describing reptile
taxonomy, ecology, morphology, life history, physiology, behaviour, and
conservation status. This processed dataset retains five elevational or
climatic attributes and seven morphological, life-history, or physiological
variables for use with PNC.

Species names and higher taxonomy follow the Reptile Database taxonomy
adopted by ReptTraits. Trait values and units were retained as provided in
the source database. No additional unit conversions, transformations, or
imputations were applied when preparing this PNC subset. Missing values are
represented by \code{NA}, and coverage varies among variables.

The \code{Maximum_length} variable represents snout-vent length for most
reptile groups but straight carapace length for turtles. The three clutch
or litter-size variables provide related summaries of the same reproductive
dimension and should not be treated as independent traits in multivariate
analyses.
