This richness of herpetofauna other groups of Huerta-Martínez et al., 2014). vertebrates has generated an increasing interest in protecting these species by establishing Areas Protegidas Naturales (APN), which at present number 182, allocated to different categories, such as national parks, biosphere reserves, and natural monu- ments (CONANP, 2017). Although Mexico is recognized as one of the most biodiverse countries in the world, there are still regions lacking exhaustive studies, such as Volcán de Tequila in the state of Jalisco. The herpetological richness for the state stands as that documented by Cruz-Sáenz et al. (2009, 2017). Volcán de Tequila is located in the municipality of Tequila, in central Jalisco between 20E45' and 20E49'N, and between 103E48', and 103E54'W. This volcano is part of Mexico’s Trans- volcanic Belt, one of the most herpetofaunal rich regions in the country and a boundary between the Nearctic and Neotropical regions. Volcán de Tequila is the fourth highest mountain in Jalisco at 2918 masl. It has an altitudinal gradient from 1120 to 2918 masl. Dominant soil types are ortic chromic luvisol and eutric regosol (Reynoso-Dueñas, 2010; Huerta-Martínez et al., 2014). Climate on the middle part of the volcano is classified as C(w), with mean temperatures varying from 10 to 20EC, where- as in the lower part the climate is Aw(w), with average tempera- tures from 17 to 27EC. Annual precipitation varies from 800 to 1000 mm, and the most humid period occurs in summer (June to October). This volcano is 50 km east of the city of Guadalajara. A very important factor that influences profoundly the distri- bution of the herpetofauna is the different vegetation types and Location of the municipality of Tequila, Jalisco, Mexico. 1.

    Pseudoeurycea naucampatepetl. The Cofre de Perote salamander is endemic to the Sierra Madre Oriental of eastern Mexico. This relatively large salamander (reported to attain a total length of 150 mm) is recorded only from, “a narrow ridge extending east from Cofre de Perote and terminating [on] a small peak (Cerro Volcancillo) at the type locality,” in central Veracruz, at elevations from 2,500 to 3,000 m (Amphibian Species of the World website). Pseudoeurycea naucampatepetl has been assigned to the P. bellii complex of the P. bellii group (Raffaëlli 2007) and is considered most closely related to P. gigantea, a species endemic to the La specimens and has not been seen for 20 years, despite thorough surveys in 2003 and 2004 (EDGE; www.edgeofexistence.org), and thus it might be extinct. The habitat at the type locality (pine-oak forest with abundant bunch grass) lies within Lower Montane Wet Forest (Wilson and Johnson 2010; IUCN Red List website [accessed 21 April 2013]). The known specimens were “found beneath the surface of roadside banks” (www.edgeofexistence.org) along the road to Las Lajas Microwave Station, 15 kilometers (by road) south of Highway 140 from Las Vigas, Veracruz (Amphibian Species of the World website). This species is terrestrial and presumed to reproduce by direct development. Pseudoeurycea naucampatepetl is placed as number 89 in the top 100 Evolutionarily Distinct and Globally Endangered amphib- ians (EDGE; www.edgeofexistence.org). We calculated this animal’s EVS as 17, which is in the middle of the high vulnerability category (see text for explanation), and its IUCN status has been assessed as Critically Endangered.

    Other Contributions NATURE NOTES Amphibia: Anura Incilius luetkenii, Smilisca sordida, and Lithobates forreri. Predation by birds. Predation on adult anurans by tropical birds has been recorded on numerous occasions, where birds of various families (e.g., Accipitridae, Striigidae, Momotidae, Turdidae) have preyed on anurans of different families (e.g., Centrolenidae, Dendrobatidae, Hylidae, Leptodactylidae, Rhinophrynidae; Hayes, 1983; Master 1999; Toledo et al., 2007; Acosta and Morún, 2014; Ramírez-Fernández and Solís-DelValle, 2014). The majority of these events are opportunistic and associated with diet-generalist or invertebrate- and vertebrate-predator bird species (Toledo et al., 2007; Amézquita et al., 2013; Paluh et al., 2015). Here, we present information on the predation of Incilius luetkenii (Bufonidae), Smilisca sordida (Hylidae), and Lithobates forreri (Ranidae) by birds in Costa Rica. On 26 May 2013, at Área de Conservación Guanacaste, Sector Santa Rosa, Provincia de Guanacaste, Costa Rica (10°50'N, 85°37'W; WGS 84; elev. 298 m), we observed a Roadside Hawk (Buteo [Rupornis] magnirostris) feeding on an individual of Incilius luetkenii. The hawk was standing on the ground pecking and eating a dead I. luetkenii along the edge of gravel road in Tropical Dry Forest, but once it was startled flew across the road without the toad and perched on a tree approximately 5 m from the ground. We cannot determine if the hawk captured the toad or found it dead (the toad remains appeared fresh), but either of these behaviors was likely because the previous evening breeding aggregations involving I. luetkenii had occurred in the area. Although frogs and toads are import- ant dietary items for this hawk (Haverschmidt, 1972; Beltzer, 1990), this observation is the first to report I.

  • Crotalus Tancitarensis. the Tancítaro Cross-Banded Mountain Rattlesnake
    Crotalus tancitarensis. The Tancítaro cross-banded mountain rattlesnake is a small species (maximum recorded total length = 434 mm) known only from the upper elevations (3,220–3,225 m) of Cerro Tancítaro, the highest mountain in Michoacán, Mexico, where it inhabits pine-fir forest (Alvarado and Campbell 2004; Alvarado et al. 2007). Cerro Tancítaro lies in the western portion of the Transverse Volcanic Axis, which extends across Mexico from Jalisco to central Veracruz near the 20°N latitude. Its entire range is located within Parque Nacional Pico de Tancítaro (Campbell 2007), an area under threat from manmade fires, logging, avocado culture, and cattle raising. This attractive rattlesnake was described in 2004 by the senior author and Jonathan A. Campbell, and placed in the Crotalus intermedius group of Mexican montane rattlesnakes by Bryson et al. (2011). We calculated its EVS as 19, which is near the upper end of the high vulnerability category (see text for explanation), its IUCN status has been reported as Data Deficient (Campbell 2007), and this species is not listed by SEMARNAT. More information on the natural history and distribution of this species is available, however, which affects its conservation status (especially its IUCN status; Alvarado-Díaz et al. 2007). We consider C. tancitarensis one of the pre-eminent flagship reptile species for the state of Michoacán, and for Mexico in general. Photo by Javier Alvarado-Díaz. Amphib.

Ambrose, Co-Chair Professor Vance T. Vredenburg, Co-Chair Batrachochytrium dendrobatidis (Bd), a fungal pathogen that causes chytridiomycosis in amphibians, has infected >500 species and caused declines and extinctions in >200 species. Recently, a second deadly fungal pathogen that also causes chytridiomycosis, Batrachochytrium salamandrivorans (Bsal) was discovered. The presence of these lethal pathogens in international trade threatens amphibian diversity. In this dissertation, I use a novel modeling approach to predict disease risk from Bd and/or Bsal to amphibian populations in North America and Asia by incorporating pathogen habitat suitability, host availability, the potential presence of an invasive carrier species, and pathogen invasion history. First I identify Bsal threat to North American salamanders to be greatest in the Southeast US, the West Coast, and highlands of Mexico. I then ii investigate the compounded risk of Bd and Bsal in North America and find highest relative risk in those same areas and in the Sierra Nevada Mountains and the northern Rocky Mountains.

(Cryptodiral Kinosternidae), is described from the Rio Cihuatldn to the Rfo San Nicolas basins in Pacific coastal Jalisco and Colima, Mexico. It is a member of the K. scorpioides complex, and differs from other Kilrcstenton species in its reduced plastron, narrow bridge, axillary and inguinal scutes always in contact, and narrow first vertebral scute. It occurs in a variety ofaquatic habitats, and is an opportunistic feeder. Females reach sexual maturity at a carapace length of 97-107 mm (7-8 yrs), and males at about 100 mm (5-7 yrs). Females collected in early May and late June had maturing ovarian follicles but no oviductal eggs or fresh corpora lutea, suggesting that eggs are laid in July or August. Average clutch size is 3-4. Kinosternon chimalhuaca is most closely related to K. integrum and K, oaxacae based on both phylogenetic and phenetic analyses of morphological characters, and probably represents a derivative of an integrum-like ancestor that was isolated along the southwestern \Iexican coast.
