The Sierra Madre Sparrow (Xenospiza baileyi) is an endemic species of Mexico that is threatened with extinction. Its distribution is reported in two areas: One in the Transvolcanic Belt of central Mexico (La Cima) near Mexico City and the other in the Sierra Madre Occidental in northwestern Mexico (Ejido Ojo de Agua El Cazador) near the city of Durango, in the state of Durango. The habitat is the same in these two areas, and consists of sub-alpine grassland that is located in shallow valleys or shallows. In our case, "El Bajío la Cantera" of approximately 55 hectares, is mostly used in rainfed agriculture, protected from livestock grazing with wire fences, which in turn represents protection for remnants of grassland where they are the birds. “El Bajío la Cantera" belongs to Ejido 12 de Mayo, Municipality of San Dimas, Durango, where 28 males were detected singing along a 500 meter transect. This finding represents the population of the healthiest Sierra Madre Sparrow currently known, so it would be necessary to document their population trend over time. This information can help to evaluate and propose the creation of a special protection area for the species that involves joint government actions and ejidatarios tending to conserve the habitat during the reproductive season in order to increase and / or maintain the size of the population.

The state of Durango, Mexico, is situated almost in the middle of the Sierra Madre Occidental. Nearly the entire state is rocky and mountainous and there are fairly large areas which are almost inaccessible though there are numerous fertile valleys which serve to produce the grain and herbage for the cattle which are important in the economy of the state. In the mountains and in the valleys may be found abundant evidence of the activities of man over what was likely a rather long period of time; there is evidence of what appear to be several rather diverse cultures though relatively little archaeological study has been made of these cultures thus far.In the mountains in the vicinity of Mezquital some 50 miles to the south of the city of Durango are numerous caves and rockshelters. It was in one of these caves that the writer discovered a bowl (Fig. 61) which conceivably may have been an “ancestor” of true pottery.

The San Pedro Mezquital River is the seventh largest river in Mexico, and flows through the Sierra Madre Occidental into the Marismas Nacionales Biosphere Reserve, on the coast of the state of Nayarit. The present study is to conform a systematic checklist of fishes in the lower basin of the San Pedro Mezquital River. In total, 52 species were collected from 24 families. Four native species were collected (Atherinella crystallina, Poecilia butleri, Poeciliopsis latidens and Poeciliopsis prolifica) that are federally protected. Five of the collected species were new records for the state of Nayarit. This checklist constitutes a first approximation of the fish fauna present in the San Pedro Mezquital River. However, the construction of the Las Cruces dam upstream, will modify the basin hydrology, worsen the introduction of exotic species and create habitat loss, which can have immediate negative impacts on the fish communities in this region.

The Flora and Fauna Protection Area (Área de Protección de Flora y Fauna—ÁPFF) Cerro del Mohinora, is the highest mountain in northern Mexico, reaching an elevation of 3,300 meters. It constitutes one of the last high-elevation islands of alpine and subalpine vegetation known in the Sierra Madre Occidental, in the extreme southwestern part of Chihuahua. The ÁPFF Cerro del Mohinora is located near the state border and limits with Durango and Sinaloa. This type of ecosystem located at high altitudes is in danger of disappearing since only 1% or less of its original extension remains; it is considered a refuge for species with boreal affinities (McDonald et al. 2011).

Under the direction of J. Charles Kelley of Southern Illinois University, an anthropological field school carried out investigations in the State of Durango, Mexico, from June 22 to August 8, 1952, with the permission of the Instituto Nacional de Antropologia e Historia.Their camp was established on the rancho “Santa Barbara,” property of Fred Weicker, about 50 kms. west of Durango city, in the Sierra Madre Occidental. The camp was on the side of an arroyo, a branch of the Rio Mimbres, which after joining the Rio Chico, flows into the Rio Tunal. This becomes the Mesquital-San Pedro and flows into the Pacific through the State of Nayarit. The camp was approximately 2280 m. above sea level, near archaeological remains consisting of house-mounds, ceramics, and obsidian artifacts.

This contribution lists 37 new moss taxa from the State of Zacatecas, Mexico. The revised listing includes 115 species and varieties of mosses but unidentified specimens of Atrichum and Grimmia are not yet included. On account of their world distribution the taxa can be grouped in four elements: Wide Distribution, Mexican, Mesoamerican and Endemic. Fifty-seven per cent of this moss flora is widely distributed in Mexico while the remainder is known only from the Neovolcanic Belt northwards. Moss distribution in Zacatecas supports the state subdivision into two phytogeographical provinces: Sierra Madre Occidental and Altiplanicie. This moss flora seems to have originated in Tertiary times.

Tanto la niñez como la adolescencia se consideran construcciones socioculturales enmarcadas en contextos específicos. De ahí que lejos de establecer parámetros genéricos sobre la adolescencia, su estudio particular permite especificar las formas de ser adolescente en situaciones concretas. En el presente documento se aborda la construcción de las masculinidades rurales indígenas desde la comunidad y la escuela telesecundaria, para lo cual se realizaron grupos focales y entrevistas a estudiantes indígenas de telesecundaria de la Sierra Madre Occidental durante los años 2010 y 2011. Se discute la importancia de abordar la construcción de las masculinidades adolescentes en el marco de la irrupción de la escuela telesecundaria en la zona indígena en función de que la escuela telesecundaria se ha convertido en el espacio de la adolescencia indígena rural. Se concluye que la escuela tiene posibilidades de convertirse en un espacio de discusión de las propuestas comunitarias tradicionales si es capaz de replantear la funcionalidad de las masculinidades en los contextos específicos a partir de las condiciones del grupo cultural.

We report three new records of the snake Leptophis diplotropis from the southeastern and northern regions of Hidalgo State, México. These records represent the first observations of this species in the state of Hidalgo, and represent a range extension of 122.7 km north from the nearest record in Tochimilco, Puebla, México. These new records of L. diplotropis represent the best knowledge of its distribution in the Sierra Madre Oriental.
