Description

SWRC - Biotic index (Stroud Water Research Centre - Biotic index)

Usage

calculate_SWRC(
  data,
  tolerances = list(Trichoptera_Hydropsychidae = 2.8, Trichoptera = 5, Plecoptera = 1,
    Ephemeroptera = 3.6, Diptera_Athericidae = 2, Diptera_Chironomidae_white = 6,
    Diptera_Chironomidae_red = 8, Diptera_Tipulidae = 3, Diptera_other = 6, Amphipoda =
    6, Gastropoda = 7, Oligochaeta = 8, Hirudinea = 8, Coleoptera = 4.6, Mollusca = 7,
    Nematoda = 8, Coleoptera = 4.6, Megaloptera = 3, Odonata_Zygoptera = 7, Isopda = 8,
    Decapoda = 5, Hemiptera = 0),
  print_results = TRUE
)

Value

A data frame with two columns: SWRC Index (0-10) and Water Quality for each site.

Arguments

data

A data frame with predefined column names: Family, Abundance and Site. The dataset should be at the order level. If the family is not at the order level, it should be linked with an underscore (e.g., Trichoptera_Hydropsychidae).

tolerances

Tolerance values are given by default.

print_results

A logical value that determines whether or not to print the results. Defaults to TRUE.
