Abstract: RESUMEN . La presente contribucion tiene como objetivo dar a conocer seis nuevos registros deanfibios y reptiles y confirmar la presencia de una especie en Guanajuato. Los ejemplares fueroncolectados entre los anos 2003 y 2006 en varias localidades de los municipios de San Luis de la Paz,Victoria y Xichu, que actualmente forman parte de la Reserva de la Biosfera “Sierra Gorda deGuanajuato” y se depositaron en la coleccion Herpetologica de la Escuela Nacional de CienciasBiologicas, del I.P.N. Los nuevos registros de anfibios son: Chaunus marinus y Ollotis nebulifer, los dereptiles son: Sceloporus variabilis, Plestiodon tetragrammus, Boa constrictor y Masticophis flagellum. El registro de Lithobates berlandieri confirma la presencia de esta especie en Guanajuato. Palabras clave: anfibios, reptiles, Guanajuato, nuevos registros. Campos-Rodriguez, J. I., C.

TL;DR: The objective of this study was to document new host plants and the geographical distributions of Melanagromyza floris Spencer, M. tomaterae Steyskal,M.
Abstract: The objective of this study was to document new host plants and the geographical distributions of Melanagromyza floris Spencer, M. tomaterae Steyskal, M. viridis (Frost) and Ophiomyia lantanae (Froggatt). The study was carried out from August 2007 to August 2008. Puparia of these flies were collected on Tithonia sp. in Tonatico (state of Mexico); Physalis nicandroides Schltd in Atotonilco el Grande (state of Hidalgo); Tagetes erecta L. and Lantana camara L. in Huautla (state of Hidalgo) and Lantana camara L. in San Joaquin, state of Queretaro. Both flies and host plants were identified. T. erecta is a new host record for M. floris whereas P. nicandroides is a new host record for M. tomaterae. The flies M. floris and M. tomaterae are the first reports for these species in the state of Hidalgo. M. viridis is recorded from the southern part of the state of Mexico. Finally, O. lantanae is registered in two states: Hidalgo and Queretaro.

TL;DR: A parsimony‐based ancestral reconstruction on body size, femoral pores and dorsal scales and related morphological changes to geographic distribution of the species will allow best designs of comparative studies with species in the “variabilis group,” one of the earliest divergent lineages in the genus.
Abstract: The monophyly of the Sceloporus variabilis group is well established with five species and two species complexes, but phylogenetic relationships within species complexes are still uncertain. We studied 278 specimens in 20 terminals to sample all taxa in the “variabilis group,” including three subspecies in the “variabilis complex,” and two outgroups (Sceloporus grammicus and Sceloporus megalepidurus). We assembled an extensive morphological data set with discrete and continuous characters (distances and scale counts), including geometric morphometric data (landmark coordinates of three shapes), and a three‐marker molecular data set as well (ND4, 12S and RAG1). We conducted parsimony and Bayesian phylogenetic inferences on these data, including several partitioning and weighting schemes. We suggest elevating three subspecies to full species status. Therefore, we recommend recognition of nine species in the “variabilis group.” First, S. variabilis is sister to Sceloporus teapensis. In turn, Sceloporus cozumelae is sister to Sceloporus olloporus. These four species are a monophyletic group, which is sister to Sceloporus smithi. Finally, Sceloporus marmoratus is sister of the clade of five species. The other species in the “variabilis group” (Sceloporus chrysostictus, Sceloporus couchii and Sceloporus parvus) are a paraphyletic grade at the base of the tree. Our analyses reject the existence of the “variabilis complex.” We conducted a parsimony‐based ancestral reconstruction on body size (snout–vent length), femoral pores and dorsal scales and related morphological changes to geographic distribution of the species. Our phylogenetic hypothesis will allow best designs of comparative studies with species in the “variabilis group,” one of the earliest divergent lineages in the genus.

TL;DR: In this paper, a coleccionada de mamiferos for Guanajuato was presented, representing 364 especimenes of 5 families, 14 generos and 25 especies (20 roedores and 5murcielagos).
Abstract: RESUMEN . La presente publicacion tiene dos objetivos principales: 1. dar a conocer varias especiesde mamiferos que son nuevos registros para Guanajuato y 2. mencionar localidades adicionales paraalgunas especies de mamiferos que han sido colectadas previamente en el estado, incrementando sudistribucion en la entidad. Los ejemplares se colectaron durante los anos 2003 a 2006 en variaslocalidades de la Reserva de la Biosfera “Sierra Gorda de Guanajuato” y se depositaron en la Coleccionde Mastozoologia de la Escuela Nacional de Ciencias Biologicas del Instituto Politecnico Nacional.Ademas de los colectados, se incluyeron otros animales que ya se encontraban en dicha coleccion. Sepresentan 11 nuevos registros y 14 especies que aumentan su distribucion conocida en Guanajuato,representados por 364 especimenes de 5 familias, 14 generos y 25 especies (20 roedores y 5murcielagos). De estas especies destacan tres roedores endemicos de Mexico ( Peromyscus difficilis, P.levipes y P. melanophrys ). De los murcielagos,

TL;DR: The frog Hyla eximia was the most abundant amphibian species for the rainy season, while the toad Anaxyrus compactilis showed low abundance in both, dry and rainy seasons.
Abstract: In this study the diversity of amphibians and reptiles from the Cerro del Veinte, Irapuato, Guanajuato was analyzed and compared for rainy and dry seasons in a tropical dry forest. A total of 23 species were recorded, 6 amphibians and 17 reptiles of which 22 were collected in the rainy season and 12 in the dry season. The frog Hyla eximia was the most abundant amphibian species for the rainy season, while the toad Anaxyrus compactilis showed low abundance in both, dry and rainy seasons. For reptiles, the most abundant species during the rainy season were the collared lizard Sceloporus torquatus, and the turtle Kinosternon integrum, and in dry weather, the spiny lizard S. spinosus. This work contributes to the understanding of diversity patterns in seasonal tropical environments providing current information on the herpetofauna for the municipality of Irapuato, laying basis for the development of ecological studies and conservation plans for amphibians and reptiles on the site.

TL;DR: In this paper, the authors used mitochondrial DNA sequences to examine the phylogeography of Bufo valliceps and discovered the existence of two distinct clades: B. valli and B. nebulifer, and tested the current distribution of these species, based on a calibrated rate of evolution and the percent sequence divergence between the two species.

17 Aug 2001TL;DR: It is proposed balancing efforts devoted to the different disciplines in mammalogy to guarantee an adequate knowledge of the mammal fauna in Mexico.
Abstract: We reviewed and analyzed the scientific literature on mammals of Mexico, including journal articles, the series Mammalian Species, book chapters and books, published between 1890 and 1995. The references were classified according to 11 general topics and included into a database. We registered 2129 publications, of which 1826 were articles in periodical journals, 206 fascicles monographs of Mammalian Species, 40 book chapters and 45 books. Journal articles showed a significant increase in the 1950's, due to a concomitant increase in number of scientist and institutions with professional interest in mammalogy. Geographically, Veracruz has been intensively studied, reaching 22% of all publications, while Tlaxcala is the least studied, with only 1% of all publications. The 79% of these publications were authored by foreign researchers, and 82% were published in foreign journals, lead prominently by the Journal of Mammalogy with 21%. Forty percent of the publications dealt with taxonomy and phylogeny, and 36% with the geographic distribution of species. Foreign authors, mostly from the U.S.A., outnumbered Mexicans in publications, except in book chapters. In recent years, however, an increase in Mexican scientists working with mammals has resulted in a significant increase in publications. These trends showed that U.S. scientists have historically played a crucial role for the development of mammalogy in Mexico, while Mexican scientist have recently contributed significantly to this field. We propose balancing efforts devoted to the different disciplines in mammalogy to guarantee an adequate knowledge of the mammal fauna in Mexico.
