Summarises the diversity of endemic mammal species in Peru, grouped by taxonomic order. Provides counts of families, genera, and species that are endemic to Peru within each order. Optionally includes endemism rates relative to total species richness.
Value
A tibble with one row per order containing endemic species, arranged in descending order by number of endemic species, with the following columns:
- order
Taxonomic order
- n_families
Number of families with endemic species in the order
- n_genera
Number of genera with endemic species in the order
- n_endemic
Number of endemic species in the order
- n_species
(Only if
include_rate = TRUE) Total number of species in the order- endemic_rate
(Only if
include_rate = TRUE) Proportion of endemic species (0-1)- endemic_pct
(Only if
include_rate = TRUE) Percentage of endemic species (0-100)
Details
This function focuses exclusively on species that are endemic to Peru (i.e., species found nowhere else in the world). Orders without any endemic species are not included in the output.
When include_rate = FALSE (default), results are sorted by the
number of endemic species in descending order, highlighting which orders
have the highest endemic diversity.
When include_rate = TRUE, results are sorted by total species
richness in descending order, and include endemism rates to show what
proportion of each order's diversity is endemic to Peru. A summary row
labeled "Total" is appended to show overall statistics.
