Estimating Petrel Populations: Review of Literature

The data contain the original reference with metadata on year, journal, species studied, island studied, motivations for the study. We extracted published population estimates reported in each paper. Most represented a mean, but where only minima or maxima were reported we used this as the estimate, and where only minima and maxima were reported we used their average as the estimate.

To allow comparison between studies we extracted basic dispersion statistics and manipulated them to approximate confidence intervals (see paper for methods). The full dataset includes: 1. data.csv - the raw data from the literature review including information for 60 variables. 2. supplementary_code.rmd - full code for the analysis. 3. Supplementary material.docx - supporting text including methods, results and references.
