Analysis code and derived tables for: Body condition and estuarine entry of glass eels (Anguilla anguilla) at the European eel's warm southern margin

Complete analysis code, derived tables and figures behind the study of glass-eel (Anguilla anguilla) body condition and estuarine entry at a fixed reach of the lower Guadalquivir estuary (SW Spain), across 29 new-moon campaigns between January 2013 and May 2015. The primary implementation is in R (blocks 00 to 10, run by RUN.R): data preparation, the nested linear mixed model of entry density on containment degrees of freedom, the residual condition index and its allometric basis, the within-pulse decomposition at event level, the sensitivity and robustness analyses, and every figure in the article and its supplement. The blocks assert their own results: about two hundred checks compare each computed value against a reference value and report agreement or difference, and several stop the run outright if the claim they guard has stopped being true. The raw data are not included. The biometric and environmental records are owned by the Junta de Andalucía and cannot be redistributed. What is provided instead is the full set of derived, aggregated tables — campaign means, model coefficients, and every main and supplementary table — from which every number reported in the article can be verified without access to individual records. Researchers wishing to obtain the raw data should contact the corresponding author, who will apply to the Junta de Andalucía for the required authorisation. Code is released under the MIT licence; derived tables, figures and documentation under CC BY 4.0.
