traits_to_csr

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

Functions that facilitate the use of accepted taxonomic nomenclature, collection of
functional trait data, and assignment of functional group classifications to phytoplankton
species. Possible 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).
Versions 2.0.0 and later includes new functions for querying the
algaebase online taxonomic database (www.algaebase.org), however these functions require
a valid API key that must be acquired from the algaebase admin.
Note that none of the algaeClassify authors are affiliated with algaebase in any way. Taxonomic
names can also be checked against a variety of taxonomic databases using
the Global Names Resolver service via its API (<https://resolver.globalnames.org/api>). In addition,
currently accepted and outdated synonyms, and higher taxonomy, can be extracted for lists of
species from the ITIS database using wrapper functions for the ritis package.
The algaeClassify package is a product of the GEISHA (Global Evaluation of the Impacts of
Storms on freshwater Habitat and Structure of phytoplankton Assemblages), funded by CESAB
(Centre for Synthesis and Analysis of Biodiversity) and the USGS John Wesley Powell Center for
Synthesis and Analysis, with data and other support provided by members of GLEON
(Global Lake Ecology Observation Network).
