Data and code for: Leaf nitrogen, not specific leaf area, predicts which plant lineages lizards use

Abstract

Data and code for: Leaf nitrogen, not specific leaf area, predicts which plant lineages lizards use. Mohammed Al-Sayegh and Mohammad A. Almousa. Department of Science, College of Basic Education, Public Authority for Applied Education and Training (PAAET), Ardiya, Farwaniya 23167, Kuwait. VERSION 4 (October 2026) - WHAT CHANGED FROM VERSION 3 Consumer validation. The fruit-consumption compilation merged by script 00 carried 75 records whose consumer was not a lizard (mainly the pheasant Lophura swinhoii; also bees, crabs, primates, a moth and a snake). Script 19 keeps only records whose consumer is a lizard (ReptTraits species list or Squamata taxonomic path). 42 genera on the phylogeny that rested only on non-lizard consumers are now controls. Model fitting. phyloglm's likelihood surface for the phylogenetic parameter alpha has more than one optimum. Every model is now fitted from six starting values of alpha and the maximum-penalised-likelihood fit is kept (scripts 20-22, 30). Island-flora check redone with local labels (scripts 23-24): a genus counts as lizard-associated on an island only if a lizard recorded eating it occurs there (GBIF). This check is reported as inconclusive in the paper. All numbers in the paper come from script 30 (results_final/) and script 24. Version 3 numbers (GEB submission) are superseded.
