Given growing concern about worldwide amphibian population declines, it is critical to conduct continuous conservation status assessments to assist in species and habitat protection programs. In the study, we review the current data on geographic distribution, elevational range, and threat status of harlequin grogs (Atelopus) and glass frogs, two groups of Neotropical amphibians facing similar threats.
Our main goal was to distinguish the range and conservation status of harlequin frogs and glass frogs considering the most recent conservation status assessment by the International Union for Conservation of Nature (IUCN). Both groups inhabit similar environments and have aquatic larvae, yet the status of many species remains unclear.

We created a spreadsheet that includes the status of each species, location, family, Area of Occupancy (AOO), and Extent of occurrence (EOO). In addition to using IUCN data, we collected some of the data using Global Biodiversity Information Facility (GBIF) and used the Geospatial Conservation Assessment Tool (GeoCAT) to calculate AOO and EOO.

We observed notable discrepancies between species range data available in IUCN and GBIF and discuss how different range estimates affects their category and conservation status of these species.

  1. Nice poster folks! Interesting finding about narrow-range elevational limits increasing extinction risk.
