Suite of logistic and quantile regression models for the analysis of taxa responses (both in terms of occurences and abundances) to environmental conditions.
Phytoplankton Size Distributions
Phytoplankton Size Distributions is a web service designed to support the investigation of size distributions patterns of phytoplankton communities. This web service provides a user-friendly workflow allowing to perform Modality (Hartigans’ dip test), Normality or LogNormality (Anderson-Darling test, Cramer- von Mises) tests of Phytoplankton Biovolume (expressed as μm3) or Cell carbon content (expressed as pgC*cell-1) distributions. Criteria of data aggregation (i.e. spatial, temporal and EUNIS habitat type) can be selected from the users. The web service works on data resources shared on the LifeWatch Data Portal and harmonized according to the “LifeWatch Data Schema” (for more details, please see the dedicated training sections at http://training.servicecentrelifewatch.eu/course/view.php?id=5). It has been developed in the R environment (R Core Team 20017).
Phytoplankton Traits Computation
Phytoplankton Traits Computation is a web service designed to support traits-based studies of phytoplankton communities. The main purpose of this web service, based on R functions, is to provide a user-friendly workflow including all the fundamental steps for the computation of some phytoplankton traits, without using the command line. It allows to calculate morphological and demographic traits, such as hidden dimension, biovolume, surface area, surface-volume ratio, cell carbon content, density, carbon content and total biovolume (for more details about traits, please see http://thesauri.lifewatchitaly.eu/PhytoTraits/index.php). The web service works on data resources shared on the LifeWatch Data Portal and harmonized according to the “LifeWatch Data Schema” (for more details, please see the dedicated training sections at http://training.servicecentrelifewatch.eu/course/view.php?id=5). It is based on computations made in the R server (https://cran.r-project.org). WEB SERVICE SUBMISSION The Phytoplankton Traits Computation consists in two steps: 1. Selection of the input file from the knowledge bases stored in “My Knowledge” on the LifeWatch Data Portal. The knowledge bases are obtained by the “Data Advanced Search”, using different filters, on one or more data resources for which you have requested the authorisation and for those you uploaded yourself (for more details, please see the dedicated training sections at http://training.servicecentrelifewatch.eu/course/view.php?id=5). To be processed by this web service, the input file must have some mandatory fields, such as scientific name, measurement remarks, length and width for “Simplified calculation”, and scientific name, measurement remarks and linear dimensions (e.g. “a”, “b”, “c”, etc.) for “Advanced calculation” (see the next step); 2. Selection of calculation modality and desired outputs: ➔ Calculation Type: - “Simplified” approximates the taxon specific-biovolumes calculation based on 2 linear dimensions only, length and width. “scientific name”, “measurement remarks” (e.g vision of the organism, dimension more or less than 20 µm), “length” and “width” are the mandatory fields for this calculation type. - The “Advanced” modality allows a more accurate estimate of taxon-specific biovolume, but it requires more information. For each shape, at least 2 measured basic linear dimensions need to be provided from the user. The mandatory fields for this calculation type are “scientific name”, “measurement remarks” (e.g vision of the organism, dimension more or less than 20 µm) and the measured linear dimensions according to the Phytobioimaging Atlas of Shapes and PhytoTraits thesaurus (for more details, please see http://phytoplankton.lifewatch.unisalento.it/en-us/products/AtlasOfShapes.aspx?ID_Tipo=0 and http://thesauri.lifewatchitaly.eu/PhytoTraits/index.phpsee). ➔ Output Traits: allows the selection of one or more traits to be calculated and visualized in the final output data file. The user may select one or more output among hidden dimension, biovolume, surface area, surface-volume ratio, cell carbon content, density, carbon content and total biovolume EXPECTED RESULTS The web service will return an output file in .csv format, including all input data and calculated records. RESULT RETRIEVAL An email, with a link pointing to the requested output, will be sent to your address.
