Bovini - Institution: Instituto de Pesquisas Jardim Botânico do Rio de Janeiro - Address: Rua Pacheco Leão, 915 - Jardim Botânico, Rio de Janeiro, RJ, Brazil ## DATA & FILE OVERVIEWThis dataset contains the geospatial occurrence points used for conservation assessment, the final high-resolution photographic plate used in the manuscript, and the corresponding uncompressed RAW files of the botanical specimens used to compose the plate. ### File List and Description:1. Geospatial Data: - File: hydrogaster_points.geocat Description: Geospatial occurrence points of the Hydrogaster trinervis, utilized in the GeoCAT platform to calculate the Extent of Occurrence (EOO) and Area of Occupancy (AOO) for the conservation risk assessment presented in the article. 2. Final Photographic Plate (Figure 1): - File: fig1.tif Description: Final high-resolution photographic plate showing the morphological characters of the species. 3. Raw Photographic Data (RAW Files): The RAW files (.CR2) are named according to the figure number and the specific inset/letter they represent in the final plate (e.g., "1a.CR2" corresponds to inset 'a' in "fig1.tif"). These are raw, unedited photographs used for taxonomic validation. - RAW files for Figure 1: Files: 1a.CR2, 1b.CR2, 1c.CR2, 1d.CR2, 1e.CR2, 1f.CR2, 1g.CR2, 1h.CR2, 1i.CR2, 1j.CR2, 1k.CR2, 1l.CR2, 1m.CR2, 1n.CR2, 1o.CR2. Description: Uncompressed RAW images used to compose the individual insets of fig1.tif.
