La Plataforma Naturalista Como Herramienta De Ciencia Ciudadana Para Documentar La Diversidad De Anfibios en El Estado De Sinaloa, México

Abstract

La ciencia ciudadana contribuye a generar información sobre biodiversidad. En este estudio analizamos patrones de distribución, fenología y vulnerabilidad ambiental en datos no estructurados de la plataforma Naturalista sobre anfibios del estado de Sinaloa, una región de México con escasa exploración científica. Además, evaluamos la hipótesis de que las especies registradas en Naturalista no corresponden exclusivamente a un nivel de vulnerabilidad ambiental bajo o medio. En total, detectamos registros de 30 especies de anfibios pertenecientes a 10 familias, entre las que destaca la ampliación de distribución de una especie de anuro dentro de Sinaloa y observaciones relevantes sobre la historia natural de distintas especies. La familia Bufonidae presentó el mayor número de registros y Eleutherodactylidae el número más bajo de registros, pero mayor riesgo de amenaza. La mayoría de los registros de anfibios se concentraron alrededor de áreas urbanas de la planicie costera. Solo tres de las 19 áreas naturales protegidas de Sinaloa tuvieron registros de anfibios en Naturalista. Por otro lado, encontramos que todos los niveles de vulnerabilidad ambiental se encuentran registrados proporcionalmente al listado de anfibios de Sinaloa. En conjunto, los registros de Naturalista en Sinaloa permiten distinguir comunidades de anfibios, identificar sitios estratégicos y especies clave para monitorear la anfibiofauna.

Herpetofauna of the “El Mineral De Nuestra Señora De La Candelaria” Reserve: A Biological Treasure in Sinaloa, Mexico

“…It is worth noting that the iNaturalist records were exclusively categorized as "Research Grade", which are entries that include all the necesary metadata and have been identified down to the species level (Clare et al, 2019). Records with doubtful identification or location were excluded and subjected to verification or elimination, with the purpose of having in the database only those records that demonstrated higher certainty, plausibility, and accuracy in presence locations (Kittelberger et al, 2021;Castro-Bastidas & Serrano-Serrano 2022). To determine protection categories, we used the NOM-ECOL-059- SEMARNAT-2010(SEMARNAT, 2023, the Red List published by the International Union for Conservation of Nature (IUCN, 2023), and Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).…”

“…It is important to note that various studies on the herpetofauna of the state of Sinaloa have been conducted, some of which were pioneering in the 1950s and 1960s (Smith & Van Gelder, 1955;Lewis & Johnson, 1956;Duellman, 1957;Fugler & Dixon, 1961), followed by more comprehensive species lists (Hardy & McDiarmid, 1969;McDiarmid et al, 1976) and more recent studies (Lavín et al, 2004;Serrano et al, 2014;Lemos-Espinal & Smith, 2020;Castro-Bastidas & Serrano-Serrano, 2022;Aguirre-Zazueta et al, 2023a). However, it's important to mention that Sinaloa is one of the least explored states due to a long period without field studies, caused by difficulties in accessing the higher regions of the Sierra and social conflicts y 2020, se documentaron 55 especies de anfibios y reptiles en la reserva, de las cuales 34 son endémicas de México, subrayando su importancia como un refugio para la biodiversidad autóctona.…”

“…The state of Sinaloa covers an area of 58 200 km 2 , which represents approximately 2.9% of Mexican territory, ranking seventeenth among other states (INEGI, 2022). Herpetofaunal studies have identified Sinaloa as one of the ten most speciesdiverse states, with a total of 170 species, including 44 amphibians and 126 reptiles (Lemos-Espinal & Smith, 2020;Loc-Barragán et al, 2020;Castro-Bastidas & Serrano-Serrano, 2022;Lara-Resendiz & Jacobo-González, 2022;Aguirre-Zazueta et al, 2023b;Devitt et al, 2023;Grünwald et al, 2023;Payan-Cazares et al, 2023). These numbers represent approximately 12% of Mexico's herpetofauna, with 10.2% being amphibians and 12.9% reptiles according to Ramírez-Bautista et al (2023).…”

PRESENCE OF Hypopachus ustus (ANURA: MICROHYLIDAE) AFTER MORE THAN FOUR DECADES WITHOUT RECORDS IN SINALOA, MEXICO

“…The state of Sinaloa is a region in northwestern Mexico is considered to require further scientific exploration to better understand the distribution and conservation status of its local herpetofauna (Flores-Villela et al, 2004). Forty one species of amphibians have been reported for Sinaloa (Castro-Bastidas and Serrano-Serrano, 2022). However, some amphibian species have few records, or lack recent data in the state.…”
