The members of the herpetofauna are categorized among the three recognized physiographic regions of the Central Plateau, the Transmexican Volcanic Belt, and the Sierra Madre Oriental. The total number of species in each of these regions ranges from 60 in the Central Plateau to 75 in the Sierra Madre Oriental. The numbers of species shared among these three regions range from 44 between the Central Plateau and the Sierra Madre Oriental to 56 between the Central Plateau and the Transmexican Volcanic Belt. A similarity dendrogram based on the Unweighted Pair Group Method with Arithmetic Averages (UPGMA) demonstrates that of the three physiographic regions, the Central Plateau (CP) and the Transmexican Volcanic Belt (TVB) cluster at the 0.84 level, and that the Sierra Madre Oriental (SMO) clusters with the other two regions at the 0.65 level. This pattern was expected given that both the CP and TVB are relatively large areas of similar size in the state that lie adjacent to one another; in contrast, the SMO is the smallest region in the state and it is adjoined only to the CP region. The level of herpetofaunal endemism in Guanajuato is relatively high, with 56 of the 101 species categorized as country endemics. The distributional categorization of the entire herpetofauna includes 56 country endemics, 40 non-endemics, and five non-natives. The 40 non-endemic species are placed into the following distributional categories: MXUS (26), USCA (six), MXCA (four), MXSA (three), and USSA (one). The principal environmental threats to the herpetofauna of Guanajuato are agriculture, industry, forestry, cattle production, and mining. We assessed the conservation status of each native species by using the SEMARNAT, IUCN, and EVS systems, of which the EVS system proved to be the most useful. We applied the Relative Herpetofaunal Priority method to determine the rank order of the three regions, which indicates that the Transmexican Volcanic Belt is the region of greatest conservation importance. Twenty-four natural protected areas have been designated in Guanajuato. Fourteen of these areas lie within the Transmexican Volcanic Belt, which is fortunate from a conservation perspective. All but four native species have been documented in these 24 areas. Finally, we provide a set of conclusions and recommendations to help improve the future protection of the Guanajuato herpetofauna.

The litter was composed of five kittens. A larger litter size than what has been reported in wildlife. The kittens were discovered in their shelter unattended and without guard protection which is an uncommon finding.Thisobservationprovides new evidence regarding the maximum amount of kittens in an oce- lot litter, as well as its location in wildlife.

Wetlands in central Mexico are important habitats for assemblages of migratory and resident birds. To study variation in richness and abundance of waterbirds, we conducted monthly observations in 30 permanent plots throughout the Sayula Lagoon, Jalisco, Mexico, during the winter season (from October to March) from 2004-2007 and from 2009-2011. Seventy-three species were recorded; 39 species were winter visitors, and eight species are included in some risk category. The best represented families were: Anatidae, Scolopacidae and Ardeidae. Spatula clypeata and Anser caerulescens were the most abundant species. We found variation in richness between zones (only two were similar), but not between the seasons (only WS4 was different) or months (only November was different). Sayula lagoon is a highly dynamic ecosystem influenced by migration and the water inputs occurring during the rainy season.

The state's mastofauna comprises 93 species of 20 families mostly Rodentia, Chiroptera and Carnivora. The main biogeographic affinities of the state mammalian fauna are the Mexican High Plateau, the Sierra Madre Oriental and, to a lesser degree, the Bajio region and the Mexican Neovolcanic Belt. Four aspects of conservation status were considered: a) risk of species, from global to national, b) official status of species in México, c) endemicity to Guanajuato, and d) applicable international regulations. A matrix was analyzed, 20 focal species were selected and allocated to strategic priority categories: I Highest priority, II High priority, and III Medium priority; fourth category comprises extirpated species from Guanajuato. A study was conducted on species, vegetation, protected areas, registered Management Units for Wildlife Conservation (UMA), and exotic species. Native vegetation in the state is highly affected by agriculture, livestock, urban and industrial areas, and roads, even though Guanajuato has 24 natural protected areas (NPA), 23 state and one federal representing 20% of the state territory. Most records of focal species relate only to one or two natural protected areas (NPA), mainly in the Sierra Gorda. Habitat type coverage by NPA appears insufficient and the areas are not well interconnected. Two large NPA had statistically fewer focal species recorded than expected on the basis of
