Ecological Tolerance Indices

Computes the Road Tolerance Index (RTI) and the Human Footprint Tolerance Index (HFTI) for species occurrence data. It automates data cleaning and integrates spatial data (roads and human footprint) to produce reproducible tolerance metrics for biodiversity and conservation research. The HFTI calculation is based on the global human footprint dataset by Mu et al. (2022) . This package is part of a PhD thesis focused on amphibian ecology in Brazil.

Ecological Tolerance Indices (RTI & HFTI) for Species Occurrence Data

Visão Geral

O ecoTolerance is an R package designed to:

1. Calculate Road Tolerance Index (RTI) for each species occurrence point, using the distance to the nearest road.
2. Calculate the Human Footprint Tolerance Index (HFTI) for each occurrence point, by extracting the human footprint value within a surrounding buffer.
3. Generate, for each species, cartographic maps (points colored by RTI or HFTI) and density distribution plots of the indices.
4. Offer a simple way to use either internal data (roads and raster for Brazil) or external data (shapefiles and rasters from any region).
