Code and data for: Traits, threats, and popularity explain extinction risk of bird

README for Supplementary MaterialsTitle of Paper: Traits, threats, and popularity explain extinction risk of birds globally Authors: Janaina Serrano, Lars Iversen, Laura Pollock DescriptionThis README file provides an overview of the dataset, columns, and code files included in the supplementary materials for the paper titled Traits, threats, and popularity explain extinction risk of birds globally. The dataset contains information on bird species, their traits, threats they face, habitat characteristics, and popularity metrics. The associated code files are provided to facilitate reproducibility and further exploration.Files in Supplementary Materials1.

Code FilesDescriptions of the provided code files:FilenameDescriptiondataprep_birdtraitsScript for preparing and cleaning the bird trait dataset. Includes processes like data wrangling, standardization of column names, log-transformations of variables, and preparation of final input data for analysis.model_figures_scriptScript to generate the main figures from the paper. This includes plotting extinction risk models, trait relationships, and visualizations of the species' threats and popularity metrics.model_evaluation_bivmapScript for model evaluation and bivariate mapping. Evaluates the predictive performance of models and creates spatial maps to visualize overlaps modeled extinction risk and observed conservation status of birds.gtrendsScript for collecting and processing Google Trends data related to species' popularity. Retrieves search hit data, processes it for analysis, and calculates summary metrics like mean hits and log-transformed values.GBIF_download Script for collecting and processing GBIF number of observations for birds globally from 2004-2021. Retrieves GBIF data, processes it for analysis, and calculates average species observations per year.Data Usage and CitationThe dataset is provided as supplementary material for the paper and can be used for academic purposes.
