traits_to_csr {algaeClassify}

Assign phytoplankton species to CSR functional groups, based on surface to volume ratio and maximum linear dimension ranges proposed by Reynolds et al. 1988;2006

Description

Assign phytoplankton species to CSR functional groups, based on surface to volume ratio and maximum linear dimension ranges proposed by Reynolds et al. 1988;2006

Usage

traits_to_csr(
  sav,
  msv,
  msv.source = "Reynolds 2006",
  traitrange = algaeClassify::traitranges
)

Arguments

sav

numeric estimate of cell or colony surface area /volume ratio

msv

numeric product of surface area/volume ratio and maximum linear dimension

msv.source

character string with reference source for distinguishing criteria

traitrange

data frame with trait criteria for c,s,r groups. The included table can be replaced with user-defined criteria if desired. Measurements are: Surface area/volume ratio (sav), maximum linear dimension (mld) and mld*sav (msv).

Value

a character string with one of 5 return values: C,CR,S,R, or SR. CR and SR groups reflect overlap between criteria for the 3 main groups.
