“…Despite its size, the data available concerning its herpetofauna is very scarce, thereby constituting an information gap about the species distributed in the region; Flores-Villela and García-Vázquez (2014) and Lemos-Espinal et al (2018) underlined the lack of studies and species lists of herpetofauna in Zacatecas. By contrast, neighboring states have complete works on their amphibians and reptiles, such as Aguascalientes: Vázquez-Díaz and Quintero-Díaz 2005; Coahuila: Lemos-Espinal and Smith 2016a; Durango: Valdez Lares et al 2013, Lemos-Espinal et al 2018a, Lemos-Espinal et al 2019Guanajuato: Elizalde-Arellano et al 2014;Jalisco: Chávez-Avila et al 2015;Nayarit: Luja et al 2014, Woolrich-Pina et al 2016Nuevo León: Lazcano-Villarreal 1997;Lazcano-Villarreal et al 2010;Lemos-Espinal et al 2016b;Lemos-Espinal et al 2018b;and San Luis Potosí: Lemos-Espinal et al 2018c. Another problem that Zacatecas faces is the lack of publications on regional or municipal studies with venomous snakes and herpetofauna in general. There are only specific notes recorded on the state rattlesnake species of the Crotalus genus such as C. aquilus (Carbajal-Márquez et al 2015a), C. basiliscus (Ahumada-Carrillo et al 2011; Carbajal-Márquez et al 2015b); C. polystictus (Campbell and Lamar 2004; Ahumada-Carrillo 2010), C. atrox, C. lepidus, C. molossus and C. scutulatus (Campbell and Lamar 2004), C. willardi (Klauber 1949).…”

Mexico is home to a large number of reptile species and has one of the greatest diversities of venomous snakes, among which the rattlesnakes pertaining to the Crotalus genus stand out. Out of more than 40 species in the country, nine are found in Zacatecas: C. aquilus, C. atrox, C. basiliscus, C. lepidus, C. molossus, C. polystictus, C. pricei, C. scutulatus and C. willardi. Although these reptiles are important, due to their relevance in terms of ecology, cultural use and public health, their conservation is impacted by multiple factors, such as habitat fragmentation and indiscriminate killing. Thus, most species within this genus are found in some type of risk category at both the national and international level. The purpose of this study was to determine the potential distribution and diversity of rattlesnakes at the municipal level in the understudied state of Zacatecas. To do this, we analyzed and described the global distribution of nine rattlesnake species by building species distribution models, which determined their potential distribution based on a set of ecological variables and presence records. The resulting models were used to assess the diversity of rattlesnake species potentially present in each municipality within the state. Thirty-nine (67.24 %) out of fifty-eight municipalities registered at least one rattlesnake species. Fresnillo, Sombrerete and Valparaíso were some of the municipalities showing greatest diversity. Moreover, C. atrox, C. lepidus, C. molossus and C. scutulatus were the most widely found species in the state. On the other hand, C. basiliscus, C. polystictus, C. pricei and C. willardi were rarely spotted and so, information on their distribution patterns within Zacatecas is limited. Finally, the areas having the largest potential for the distribution of these species were defined. These findings should make field work much more time- and cost-effective, facilitating the collection of in situ data that are useful for management and conservation plans of these species in Zacatecas.

“…These results suggest that the herpetofauna, especially the reptiles, of Sonora is considered to be of relatively low conservation concern at a global scale, but there is much greater conservation concern at a national level. Indeed, more local assessments (SEMARNAT and EVS ) are based on information specific to Mexico and thus are more likely to reflect the conservation needs of the Sonoran herpetofauna (see Lemos-Espinal et al 2018a , b for a similar assessment for other Mexican states). There are several taxa that, based on their IUCN listing, SEMARNAT category or their EVS , are of conservation concern.…”

Sonora has a rich natural diversity, including reptiles and amphibians. Sonora’s location on the United States-Mexico border creates some unique conservation challenges for its wildlife. We compiled a list of the amphibian and reptile species currently known for Sonora, summarized the conservation status of these species, and compared our list of species with known species lists for adjacent states. The herpetofauna of Sonora comprises 200 species of amphibians and reptiles (38 amphibians and 162 reptiles). Overall, Sonora shares the most species with Chihuahua, Sinaloa, and Arizona. Approximately 11% of the amphibian and reptile species are IUCN listed, but 35.5% are placed in a protected category by SEMARNAT, and 32.6% are categorized as high risk by the Environmental Vulnerability Score.

“…We determined the conservation status of each species from the IUCN Red List 2019-2 ( IUCN 2019 ), SEMARNAT (2010) , and Environmental Vulnerability Scores ( Wilson et al 2013a , b ; Johnson et al 2015 ). We determined the number of species found in Sinaloa that were shared with the four neighboring states using recent herpetofaunal check lists for Sonora ( Lemos-Espinal et al, 2019a ), Chihuahua ( Lemos-Espinal et al 2017 ), Durango ( Lemos-Espinal et al 2019b ), and Nayarit ( Woolrich-Piña et al 2016 ). We also included the Baja California Peninsula in this comparison, using Grismer (2002) and Hollingsworth et al (2015) as species lists, since it used to be contiguous with the states of Sinaloa and Sonora .…”

Sinaloa possesses a rich biota with unique characteristics due to its proximity to the northern deserts, the tropical lowlands of the south, and the temperate environments of the western slopes of the Sierra Madre Occidental in Mexico. However, threats to its environment makes understanding the biological diversity of Sinaloa crucial. A checklist of the amphibians and reptiles has been generated, and the conservation status of Sinaloa’s herpetofauna summarized with the aim of understanding the potential conservation or management needs. Sinaloa has 159 species of amphibians and reptiles, including 39 species of amphibians and 120 species of reptiles. The herpetofauna of Sinaloa has relatively few species of conservation concern at a global and national scale (IUCN and SEMARNAT lists), but Environmental Vulnerability Scores suggest that there might be greater conservation concerns for the Sinaloa herpetofauna. Families of particular conservation concern include Craugastoridae, Eleutherodactylidae, Ambystomatidae, Crocodylidae, Dactyloidae, Eublepharidae, Helodermatidae, Iguanidae, Phrynosomatidae, Phyllodactylidae, Colubridae, Natricidae, Viperidae, Cheloniidae, and Dermochelyidae.
