The diversity and conservation status of amphibians and reptiles from the Mexican biogeographic province of Sierra Madre del Sur

Nature Conservation, Journal Year: 2025, Volume and Issue: 58, P. 101 - 127

The Sierra Madre del Sur (SMS) is a biologically diverse biogeographic province found in south-central Mexico. It therefore an area of interest from conservation standpoint. Here we examine the diversity and status amphibians reptiles SMS its subprovinces determine their similarity with neighboring provinces. We compiled list species occurring provinces available literature gathered information on status. also herpetofauna three (Western, Central, Eastern). houses 186 amphibians, which 89% are endemic to Mexico 53% SMS. contains 331 reptile species, 72% 23% amphibian concentrated Eastern subprovince. significant number highlights importance for conservation. Comparison shows that shares 33% Transvolcanic Belt, 25% Pacific Lowlands Balsas Basin, 19% Veracruzan. 52% 42% Lowlands, 40% results cluster analyses suggest does not represent single unit terms herpetofauna, since do together. Western Central Basin whereas subprovince clusters separately. 25.7% evaluated included International Union Conservation Nature’s (IUCN) Red List some category concern (amphibians: 54.9%; reptiles: 6.8%). hosts highest proportion (93.8%). important increase areas protected by federal state governments, especially subprovince, promote protections driven local communities.

Completeness of the amphibian inventory of Nayarit, Mexico, assessed from biodiversity information system records

Ecoscience, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 14

Published: Nov. 18, 2024

Climate change, diseases, pollution, and land cover changes threaten amphibian species worldwide, making identifying monitoring these crucial for the conservation of biodiversity. Nayarit, which is located in northwestern Mexico within Mexican Transition Zone Neotropical biogeographic regions, hosts high diversity. However, information on completeness inventory Nayarit lacking. Thus, objective present study was to evaluate using open-access biodiversity systems. We constructed a database from stored National Biodiversity Information System (SNIB) Commission Knowledge Use (CONABIO). Inventory analysed 10-km cells various periods, considering physiographic regions. Areas with were defined by their proximity main communication routes rather than biophysical reasons. Approximately half state exhibited gaps, especially mountainous difficult-to-access areas. Additional studies are needed fully document diversity geographical regions few records. Our results provide solid foundation future research essential adequately conserving managing natural resources Nayarit.
