GEISHA has produced a functional classification to facilitate the use of robust, repeatable functional classification systems. The “algaeClassify” R-package, is available on the CRAN repository. It contains R-code designed to facilitate the application of common morpho-functional (MFG;  Salmaso et al. 2015 <doi:10.1111/fwb.12520>) and life-history classifications (CSR, Reynolds 1988) to phytoplankton species lists and/or trait datasets.

Title: Determine Phytoplankton Functional Groups Based on Functional Traits

Author(s): Vijay Patil [aut, cre],  Torsten Seltmann [aut],  Nico Salmaso [aut], Orlane Anneville [aut], Marc Lajeunesse [aut], Dietmar Straile [aut] 

Maintainer: Vijay Patil <>

Description: Verify accepted taxonomic nomenclature of phytoplankton species, assign species to functional group classifications, and manipulate taxonomic and functional diversity data. Possible functional classifications include Morpho-functional group (MFG; Salmaso et al. 2015 <doi:10.1111/fwb.12520>) and CSR (Reynolds 1988; Functional morphology and the adaptive strategies of phytoplankton. In C.D. Sandgren (ed). Growth and reproductive strategies of freshwater phytoplankton, 388-433. Cambridge University Press, New York). It also includes functions to query names using the algaebase online taxonomic database (<>; <doi:10.7872/crya.v35.iss2.2014.105>).
