DOWNLOAD EBOOKThe Museum of Vertebrate Zoology (MVZ), located on the campus of the University of California, Berkeley, is a leading center of herpetological research in the United States. This monograph offers a brief account of the principal figures associated with the collection and of the most important events in the history of herpetology in the MVZ during its first 93 years, and lists all type specimens of recent amphibians and nonavian reptiles in the collection. Although the MVZ has existed since 1908, until 1945 there was no formal curator for the collection of amphibians and nonavian reptiles. Since that time Robert C. Stebbins, David B. Wake, Harry W. Greene, Javier A. Rodríguez-Robles (in an interim capacity), and Craig Moritz have served in that position. The herpetological collection of the MVZ was begun on March 13, 1909, with a collection of approximately 430 specimens from southern California and as of December 31, 2001, contained 232,254 specimens. Taxonomically, the collection is strongest in salamanders, accounting for 99,176 specimens, followed by "lizards" (squamate reptiles other than snakes and amphisbaenians, 63,439), frogs (40,563), snakes (24,937), turtles (2,643), caecilians (979), amphisbaenians (451), crocodilians (63), and tuataras (3). Whereas the collection's emphasis historically has been on the western United States and on California in particular, representatives of taxa from many other parts of the world are present. The 1,765 type specimens in the MVZ comprise 120 holotypes, three neotypes, three syntypes, and 1,639 paratopotypes and paratypes; 83 of the holotypes were originally described as full species. Of the 196 amphibian and nonavian reptilian taxa represented by type material, most were collected in México (63) and California (USA, 54). The Appendix of the monograph presents a list of curators, graduate and undergraduate students, postdoctoral fellows, research associates, research assistants, curatorial associates, curatorial assistants, and visiting faculty who have conducted research on the biology of amphibians and reptiles while in residence in the Museum of Vertebrate Zoology as of December 31, 2001.

DOWNLOAD EBOOKThe Coast Horned Lizard (Phrynosoma coronatum blainvillii) is a native species of special concern in California. One of the major threats to Coast Horned Lizards, particularly in southern California, is habitat loss and fragmentation. Studies have suggested that the Coast Horned Lizard selects habitats in chaparral and coastal sage scrub vegetation with friable sandy soils and low to moderate slope percent rise. The Santa Monica Mountains National Recreation Area (SMMNRA), located in Los Angeles and Ventura counties, is within the known range of Coast Horned Lizard inhabitation. Due to ecologically disruptive human activity in and around the SMMNRA, potential Coast Horned Lizard highly suitable habitat may be at risk of fragmentation, decrease in suitability and/or complete loss of habitat. This study identifies areas of high Coast Horned Lizard suitability so that these areas may be further studied in regards to actual species presence and human impact. Habitat suitability models and landscape pattern were analyzed to investigate the extent to which the SMMNRA is suitable for Coast Horned Lizard inhabitation. First, three habitat suitability models were used to classify the habitat suitability of areas in the SMMNRA depending on designated habitat needs such as slope, soil type, and vegetation cover. Then landscape metrics were used to measure habitat fragmentation, particularly for highly suitable areas. In the SMMNRA, 70% of the total land area was found to meet the majority of the habitat suitability criteria (high suitability, HSA) or some of these requirements (high-medium suitability, HMSA) for the Coast Horned Lizard. HMSAs covered from 59% to 66% of the SMMNRA, depending on the model's weighting. Similarities in percent areas were observed between the results for model 1 and model 3. Model 2 showed significantly higher HSA percent (11%) than other models (3%) due to increased vegetation weighting. The landscape patterns and metrics of the SMMNRA showed that most of the area is at least HMSA for Coast Horned Lizards. Fragmentation occurred in areas of human impact but did not prevent the connection of suitable habitats within the interior mountain range. Other factors of suitability should be explored in respect to the SMMNRA to gain a more accurate assessment of Coast Horned Lizard habitat. In addition, field surveys would be needed to confirm actual Coast Horned Lizard presence.
