Other Contributions NATURE NOTES Amphibia: Caudata Ambystoma ordinarium. Predation by a Black-necked Gartersnake (Thamnophis cyrtopsis). The Michoacán Stream Salamander (Ambystoma ordinarium) is a facultatively paedomorphic ambystomatid species. Paedomorphic adults and larvae are found in montane streams, while metamorphic adults are terrestrial, remaining near natal streams (Ruiz-Martínez et al., 2014). Streams inhabited by this species are immersed in pine, pine-oak, and fir for- ests in the central part of the Trans-Mexican Volcanic Belt (Luna-Vega et al., 2007). All known localities where A. ordinarium has been recorded are situated between the vicinity of Lake Patzcuaro in the north-central portion of the state of Michoacan and Tianguistenco in the western part of the state of México (Ruiz-Martínez et al., 2014). This species is considered Endangered by the IUCN (IUCN, 2015), is protected by the government of Mexico, under the category Pr (special protection) (AmphibiaWeb; accessed 1April 2016), and Wilson et al. (2013) scored it at the upper end of the medium vulnerability level. Data available on the life history and biology of A. ordinarium is restricted to the species description (Taylor, 1940), distribution (Shaffer, 1984; Anderson and Worthington, 1971), diet composition (Alvarado-Díaz et al., 2002), phylogeny (Weisrock et al., 2006) and the effect of habitat quality on diet diversity (Ruiz-Martínez et al., 2014). We did not find predation records on this species in the literature, and in this note we present information on a predation attack on an adult neotenic A. ordinarium by a Thamnophis cyrtopsis. On 13 July 2010 at 1300 h, while conducting an ecological study of A. -

Bull Snake Class: Reptilia
Pituophis catenifer sayi Bull Snake Class: Reptilia. Order: Squamata. Family: Colubridae. Other names: Gopher Snake, Pine Snake Physical Description: Bull snakes are usually yellow in color, with brown, black or reddish colored blotching or saddle spots on the sides of the snake. There are dark spots placed between the blotches or saddle spots. Below this is a further row of smaller dark spots. The belly is light brown. Many variations in color have been found, including albinos and white variations. This snake has a small head and a large nose shield, which it uses to dig. They often exceed 6 feet in length, with specimens of up to 100 inches being recorded. Males are generally larger then females. The bull snake is a member of the family of harmless snakes, or Colubridae. This is the largest order of snakes, representing two-thirds of all known snake species. Members of this family are found on all continents except Antarctica, widespread from the Arctic Circle to the southern tips of South America and Africa. All but a handful of species are harmless snakes, not having venom or the ability to deliver toxic saliva through fangs. Most harmless snakes subdue their prey through constriction, striking and seizing small rodents, birds or amphibians and quickly wrapping their body around the prey causing suffocation. While other small species such as the common garter snake lack powers to constrict and feed on only small prey it can overpower. Diet in the Wild: Bull snakes eat small mammals, such as mice, rats, large bugs as well as ground nesting birds, lizards and the young of other snakes. -

The Striped Whipsnake (Masticophis taeniatus) occurs across 11 western U.S. states and into Mexico but has experienced population declines in parts of its range, particularly in the state of Washington. We analyzed nuclear and mitochondrial DNA extracted from 192 shed skins, 63 muscle tissue samples, and one mouth swab to assess local genetic diversity and differentiation within and between the last known whipsnake populations in Washington. We then placed that information in a regional context to better understand levels of differentiation and diversity among whipsnake populations in the northwestern portion of the range of the species. Microsatellite data analyses indicated that there was comparable genetic diversity between the two extant Washington populations, but gene flow may be somewhat limited. We found moderate to high levels of genetic differentiation among states across all markers, including five microsatellites, two nuclear genes, and two mitochondrial genes. -
3.7 Biological Resources
3.7 BIOLOGICAL RESOURCES EXECUTIVE SUMMARY This section identifies major plant and animal resources within the City’s Planning Area and assesses the potential impacts of the proposed General Plan on biological resources with the understanding that certain resources, especially wildlife, are transitory and may potentially be present in a wide variety of areas regardless of previous records of observation. The City’s Planning Area consists of its incorporated boundaries and adopted Sphere of Influence (SOI). The County’s Planning Area consists of unincorporated land within the One Valley One Vision (OVOV) Planning Area boundaries that is located outside the City’s boundaries and the adopted SOI. The City and the County Planning Areas together comprise the OVOV Planning Area. A substantial portion of the area within the City has been developed. Species within the remaining natural areas are adapted to the Mediterranean climate of the region, in that they thrive in the cool, wet winters, and dry, hot summers typical of the area. Within the City boundaries, these areas include the Santa Clara River through the City; and portions of San Francisquito Canyon, Sand Canyon, Whitney Canyon, and Placerita Canyon. The major natural features of the City’s adopted SOI include the Liebre Mountains south of the National Forest boundary, including Cruzan Mesa and portions of Tick Canyon, Mint Canyon, Bouquet Canyon and San Francisquito Canyon; and the San Gabriel Mountains north of the National Forest boundary, including portions of Sand Canyon and -
Observation of a Gopher Snake (Pituophis Catenifer)Constricting a Red-Tailed Hawk (Buteo Jamaicensis)
LETTERS J. Raptor Res. 46(3):000–000 E 2012 The Raptor Research Foundation, Inc. OBSERVATION OF A GOPHER SNAKE (PITUOPHIS CATENIFER)CONSTRICTING A RED-TAILED HAWK (BUTEO JAMAICENSIS) KEY WORDS: Red-tailed Hawk; Buteo jamaicensis; gopher snake; Pituophis catenifer; predation. On 5 September 2008 at 0928 H, I observed an approxi- mately 1.6-m (total length) gopher snake (Pituophis cateni- fer) constricting an adult Red-tailed Hawk (Buteo jamaicensis) on the side of Forest Road 10 in the Cibola National Forest near Magdalena, New Mexico, U.S.A. (34u10.389N, 107u25.059W), at an elevation of 2265 m asl. After approach- ing the snake, I noticed that the hawk was still alive but struggling to breathe, as it was immobilized by the snake (Fig. 1). The snake had coils around the throat, chest, and wings of the hawk. The Red-tailed Hawk did not have the gopher snake grasped in its talons or in its bill, and the snake did not have any visible external injuries. When I approached, the snake exhibited typical defensive behavior, including hissing and striking toward me (Sweet 1985, Young et al. 1995). Approximately 12 min (0940 H) after I began my observation, the snake released the hawk, per- Figure 1. Gopher snake constricting a Red-tailed Hawk haps due to my close proximity. Now released, the hawk on 5 September 2008 near Magdalena, New Mexico, U.S.A. quickly stood up, spread its wings, and stood back about 2 m from the snake for approximately 30 sec. It then flew first indication that gopher snakes may possibly represent into a dead tree 10 m away, where it rested for 2 min, before an occasional source of mortality for healthy adult Red- it flew off the side of the hill and out of view. -

Banta' Introduction This report is one of a planned series of analyses of reptile speci- mens taken from the Great Basin and now deposited in the major institutional repositories of the western United States. We hope and anticipate that such reports will provide a more adequate systematic and distributional picture of the Great Basin reptile fauna. At present we are concerned mainly with the species occurring in this region and specimen locality data If such can be completed we would then perhaps have a nearly complete list of species and subspecies occurring in the basin as well as the distribution limits of each. -
