cfa5a24b-5912-48af-8244-bdf301d77b41 1.0 Crustaceans Trophic Position Analyzer 2024-08-30 A service that aims at calculating the trophic position of the consumer (i.e. invader) by using a Bayesian model and stable isotope data of one prey species used as a baseline. The service replaces the NA values of the consumer's trophic position within the column "trophicLevel” of the "SIA.csv” with the numeric value of the estimated trophic position within the output file "troph_SIA.csv". This service uses the R package tRrophicPosition v. 0.8 that is based on a powerful approach of Markov Chain Monte Carlo simulations provided by JAGS.<div>It is part of the Crustaceans workflow of the Internal Joint Initiative available here: <a href="https://metadatacatalogue.lifewatch.eu/srv/eng/catalog.search#/metadata/91abf89b-bd2e-4867-af43-0618892e06dd" target="_blank">https://metadatacatalogue.lifewatch.eu/srv/eng/catalog.search#/metadata/91abf89b-bd2e-4867-af43-0618892e06dd</a>.</div> Giorgio Mancinelli Department of Biological and Environmental Sciences and Technologies, University of Salento, Lecce, Italy giorgio.mancinelli@unisalento.it Antonio José SÁENZ-ALBANÉS LifeWatch ERIC ICT Core aj.saenz@lifewatch.eu Lucia Vaira LifeWatch ERIC Service Centre lucia.vaira@lifewatch.eu ICT Core Group LifeWatch ERIC ICT Core ict.coordination@lifewatch.eu https://metadatacatalogue.lifewatch.eu/srv/api/records/cfa5a24b-5912-48af-8244-bdf301d77b41/attachments/crustaceans.jpg crustaceans.jpg functional traits modelling alien invasive species native species trophic position Crustaceans IJI GPLv3 Tax_validated_SIA.csv http://metadatacatalogue.lifewatch.eu/srv/eng/catalog.search#/metadata/46df37ac-4c92-433f-a213-b50553cee4f5 It is an intermediate file of the Crustaceans workflow that contains the validated SIA file by identifying the native and invasive species.
