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> functional traits modelling alien invasive species native species trophic position Crustaceans IJI WWW:LINK-1.0-http--link https://metadatacatalogue.lifewatch.eu/srv/eng/catalog.search#/metadata/91abf89b-bd2e-4867-af43-0618892e06dd WWW:LINK-1.0-http--link https://my.lifewatch.eu/workflow/create-workflow-from-template/crustaceans license Open Access Department of Biological and Environmental Sciences and Technologies, University of Salento, Lecce, Italy LifeWatch ERIC ICT Core LifeWatch ERIC Service Centre Giorgio Mancinelli Antonio José SÁENZ-ALBANÉS Lucia Vaira ICT Core Group
