Visually assess change in sampling effort over time (author: Dietmar Straile)

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' administrators.
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currently accepted and outdated synonyms, and higher taxonomy, can be extracted for lists of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 U.S. Geological Survey John Wesley Powell Center for
Synthesis and Analysis, with data and other support provided by members of GLEON
(Global Lake Ecology Observation Network).
