Displays summary information about the ecoregions used in the Peruvian mammal backbone. Ecoregions follow the Brack-Egg (1986) classification system used in Peruvian biogeography to describe the distribution of mammal species across different ecological regions.
Value
A tibble with one row per ecoregion, arranged in descending order by species richness, with the following columns:
- ecoregion_code
Abbreviated ecoregion code (e.g., "SB", "YUN")
- ecoregion_label
Full ecoregion name in Spanish
- n_species
Total number of mammal species recorded in the ecoregion
- pct_species
Percentage of Peru's total mammal diversity (0-100)
- n_endemic
(Only if
include_endemic = TRUE) Number of endemic species in the ecoregion- pct_endemic
(Only if
include_endemic = TRUE) Percentage of endemic species relative to total species in the ecoregion (0-100)
Details
The ecoregion classification follows Brack-Egg (1986), a widely-used biogeographic framework for Peru that recognizes 10 distinct ecological regions based on climate, vegetation, and elevation. This classification is used in Pacheco et al. (2021) to document the distribution patterns of Peruvian mammals.
The function prints a formatted summary to the console and invisibly returns the complete data for further analysis.
