Amphibian reproductive modes: a systematic review mapping global research patterns and evaluating climatic associations

File Structure and Descriptions: Appendix S1 - List of Studies: Complete list of all academic works identified in the systematic review, including Study ID, authors, titles, DOI and publication years. Appendix S2 - Research Scopes: Definitions and criteria for the nine research categories (e.g., Bioacoustics, Physiology, Natural History) used to classify the literature. Appendix S3 - Reproductive Mode Classification: A detailed cross-reference table showing how the specific modes from Nunes-de-Almeida et al. (2021) were grouped into our four major categories (Aquatic, Terrestrial, Arboreal, and Mixed), including biological definitions for each. Appendix S4 - Species List: A taxonomic list of all amphibian species analyzed in this study, organized by scientific name and taxonomic order. Appendix S5 - Model Averaging Results: (S5.1 to S5.4) containing full and conditional average coefficients and p-values.
