  • The Atlas of phytoplankton is a guide for the identification of marine and freshwater species. It includes pictures, synonyms, morphological, morphometric and ecological characteristics and geographical distribution of the taxa. It also provides formulas to calculate the biovolume and surface area based on linear dimensions according to the organism view (e.g., lateral, frontal, etc.).

  • The Atlas of Shapes includes an illustrative scheme of the shapes subdivided in “Simple Shapes” and “Complex Shapes”. Clicking on a specific shape, users are able to see: the code and the name of the shape, the shape view (e.g., lateral, frontal, etc.) with the corresponding linear dimensions, the biovolume and surface area computational models with all the formulae associated. Clicking again on a specific shape, users will be redirected to all taxa present in the Atlas of Phytoplankton that are characterized by the selected shape. Atlas of shapes and Atlas of phytoplankton are integrated and can be easily joint switching from taxonomic identification to morphological characterization of phytoplankton.

  • The Traits Computation web service provides a user-friendly Graphical User Interface (GUI) that allow researchers to run a workflow wrapped into R code for the computation of morphological and demographic traits, such as biovolume, surface area, surface-volume ratio, density, cell carbon content, density, carbon content and total biovolume. The service works on datasets structured according to the Phytoplankton Data Template that can be selected by the GUI or uploaded by the researchers. The input file is in CSV format with some mandatory fields according to the calculation type. Before selecting or uploading the input file, users have to specify some parameters (e.g., the calculation type, and the traits to be computed). The web service provides as output a file in .csv format, including all input data and the new calculated traits.
