Jaguars and pumas are top-predator species in the Neotropics that are threatened by habitat destruction, illegal poaching of their body parts and their favored prey, and by the human–wildlife conflicts that arise when predators attack livestock. Much of the remaining felid habitat in the Americas is in protected nature reserves that are too small a...

Bats are important reservoirs of viral entities that cause diverse economical and health problems in several sectors. The purpose of this study was to determine the prevalence of the rabies virus in vampire bats. We also tested for 3 other zoonotic viruses in the collected tissue. We captured 45 vampire bats (Desmodus rotundus), which were measured...

Knowledge of the diversity of terrestrial vertebrates in the Sierra La Mojonera Natural Protected Area and its surroundings is quite limited. Therefore, the objectives of this study were to update the list of terrestrial vertebrate species that inhabit the area of influence of the Sierra La Mojonera, to investigate the subspecies, and to highlight...

Biological collections have become a key tool for biodiversity research. They are repositories of germplasm and data on modified or extinct natural populations, providing valuable information for understanding anthropogenic impacts on the natural world. We appraised the scientific value of the three mammal collections maintained by the Instituto Po...

México es el país con mayor diversidad de víboras de cascabel, con 47 de las 53 especies descritas a nivel mundial, de las cuales 28 son endémicas. Sin embargo, se desconoce la riqueza, abundancia y el estado de conservación del género Crotalus en la Reserva de la Biosfera Mapimí (RBM), particularmente en los estados de Durango y Chihuahua y en un...

Abstract Bat acoustic libraries are important tools that assemble echolocation calls to allow the comparison and discrimination to confirm species identifications. The Sonozotz project represents the first nation-wide library of bat echolocation calls for a megadiverse country. It was assembled following a standardized recording protocol that aimed...

Correspondent: celialg@prodigy.net.mx Peromyscus melanophrys is a Mexican endemic distributed in seasonal tropical forests and semiarid lands. Molecular work based on mitochondrial and nuclear markers proposed the existence of four haplogroups within P. melanophrys. Peromyscus mekisturus (Puebla deer mouse) was included in one of these haplogroups....

El libro de los anfibios y reptiles de Guanajuato incluye información general sobre las caracteristicas morfologicas, biologicas y de distribución de las especies de estos grupos de vertebrados en el Estado. Tambien incluye una clave dicotomica para la identificación de las especies, asi como otros aspectos como etnoherpetologia, estrategia estatal...

Establishing the limits on the distribution of Gerrhonotus infernalis in Guanajuato state has been relatively complicated, and the presence of this species was uncertain until recently. This paper confirms the presence of Gerrhonotus infernalis for the state, expanding the range of the distribution known for the northeast of the state, based on thr...

We studied the diet and foraging behavior of bobcats (Lynx rufus) in the Chihuahuan desert, Mexico, from 2005-2007 to test if bobcats will select energetically profitable prey regardless of their relative abundance. We estimated frequency of occurrence and percentage of occurrence for species of prey in the diet through analysis of scats (n=117) an...

Introduction: Photographic records are useful tools that had strengthen wildlife mammal studies as a noninvasive methodology providing a wide variety of information. The objective of this study is to document with images (automatic -trail cameras and manually – personal cameras) the species of mammals inhabiting the Mapimi Biospere Reserve (MBR), t...

Study of a bat community from San Luis de la Paz, Guanajuato, Mexico. In order to describe the bat community of San Luis de la Paz, México, abundance, size and trophic guild of the specimens were associated with their habitat, and diversity, equitativity, species richness, and dominancy were estimated. The highest diversity was shown in succulent-r...

We present a new record of Geophis latifrontalis for the Mexican state of Guanajuato. This specimen was collected in the municipality of Xichú, Guanajuato. Previews records of this species were reported from Moctezuma, San Luis Potosí and Pinal de Amoles, Querétaro, so this specimen extends the know distribution of this species into the western slo...

Previous records of this species were reported from Moctezuma, San Luis Potosí and Pinal de Amoles, Querétaro. This specimen extends the known distribution of the species into the western slope...

Home range size, daily travel distances, and diel activity patterns are important characteristics of how an animal uses its home range area. In species, such as the bobcat (Lynx rufus), with large geographical ranges, it is necessary to gather data on diverse populations across the range to better understand what might be factors influencing these...

Updated information on the geographic and taxonomic representativeness of mammal specimens deposited in 28 Mexican mammal collections, the Mammal Networked Information System (MaNIS), and the Unidad de Informática para la Biodiversidad (UNIBIO) data bases were compiled in order to analyze and compare the overall current status of the specimens of M...

Leucism is a partial hypopigmentary congenital disorder previously recorded in Mexico in seven bat specimens of six species. In August 2009, in the state of Hidalgo, we caught one Sturnira ludovici and one Artibeus lituratus (both females) exhibiting leucism. In addition, one leucistic Macrotus waterhousii was caught in April 2010, in Guerrero. Leu...

Los mamíferos de México en las colecciones científicas de Norteamérica

La presente publicación tiene dos objetivos principales: 1. dar a conocer varias especies de mamíferos que son nuevos registros para Guanajuato y 2. mencionar localidades adicionales para algunas especies de mamíferos que han sido colectadas previamente en el estado, incrementando su distribución en la entidad. Los ejemplares se colectaron durante...

Five new reptile records for the Mexican state of Guanajuato are reported: Lampropeltis triangulum dixoni, Leptodeira annulata cusiliris, Oxybelis aeneus, Tropidodipsas sartorii, and Scincella silvicola caudaequinae. These records are within western versant of the Sierra Gorda at Sierra Gorda de Guanajuato. Evidence is given that supports the idea...

Se analizó la estructura anatómica e histológica de la lengua del murciélago frugívoro Centurio senex, y se comparó con la descrita para otras especies de quirópteros, para conocer si existen estructuras particulares que pudieran estar asociadas a su tipo de alimentación. La lengua de este murciélago es corta, redondeada y posee numerosas papilas f...

The anatomy and histology of the tongue of Noctilio leporinus, a mainly piscivorous bat, were studied to search for any special character which could be associated to this feeding type. The surface of the tongue has three kinds of papillae: filiform, fungiform and circumvallate. At the histological level, only the two last ones have taste buds. The...
