Functions for generating gridded biodiversity maps from point (incidence) data

R functions for generating gridded biodiversity maps from point (incidence) data

===================================================

biomapME contains R functions for manipulating, analysing and rasterising ecological data for use in macroecological analysis and mapping of biodiversity metrics. The functions are primarily geared towards generating gridded biodiversity maps based on various metrics from species incidence data.

biomapME is currently under revision (as of 2020) to add additional functionality. The 'original' v1.0 functions (cited in various publications) can be found in the archived version cited below. However, some aspects do not work in the archived scripts due to changes in underlying package dependencies. These glitches have been corrected in v2.0.

The main purpose of the package is to provide R functionality for taking simple input data (i.e., georeferenced species records) and calculating biodiversity metrics for raster maps (or sites). Results are generally returned as automatically generated raster maps and in numeric formats.

biomapME contains functions for calculating species richness, phylogenetic diversity, 'weighted endemism' (and its various guises including phylogenetic endemism and georeferenced range span/area implementations), with non-parametric tests for higher diversity than expected by chance. Supporting functions include calculation of various range metrics (batch-processed for multiple species and includes number of occupied grid cells, extent of occurrence (range span, range area), and longitudinal/latitudinal range), generation of species presence-absence matrices for species within map grid cells, conversion of plot based species occurrence matrices into individual species records, and batch-processed habitat fragmentation/class statistics for circular buffers around focal sites (useful for testing landscape influence on site-based metrics, for example).

The current version of biomapME can be installed and accessed as follows:
