Biodiversity and biogeography of the avifauna of the Sierra Madre Occidental, Mexico
Biodiversity and Conservation, 2014The Sierra Madre Occidental (SMOc) is located in the boundary between the Nearctic and Neotropical regions, area which has been considered as a complex transition zone. We analysed biogeographic patterns of its resident avifauna, including species richness, endemism, and biotic regionalization by analysing presence-absence matrices of 148 species of ...

Geological reconnaissance in northern Sierra Madre Occidental of Mexico
Bulletin of the Geological Society of America, 1939INTRODUCTION GENERAL STATEMENT The crests of the Sierra Madre Occidental, in the western part of Mexico, form the boundary between the west coast States of Sonora and Sinaloa and the interior States of Chihuahua and Durango. These plateau-like crests, carved from gently inclined volcanic rocks, are in contrast to the Sierra Madre Oriental, in eastern

Seasonal variation of mammal roadkill hotspots in the Sierra Madre Occidental, México
Therya Notes, 2022Roadkill hotspots are spatially aggregated sites that are not distributed at random. In the case of mammals, hotspots are used as a criterion to assess the locations of roadkill mitigation works, although these sites can vary at different time scales.

Calderas of the Sierra Madre Occidental Volcanic Field western Mexico
Journal of Geophysical Research: Solid Earth, 1984Approximately 296,000 km2 of western Mexico is covered by a volcanic sequence that has an average thickness of 1 km and is mostly ash‐flow tuff. Although some 350 calderas are suggested by this tremendous volume, only a few have been located or described.

Surface wave studies of the Sierra Madre Occidental of northern Mexico
Bulletin of the Seismological Society of America, 1999AbstractSeismograms originating from earthquakes in the Gulf of California and recorded in West Texas (TXAR) were used to construct Rayleigh wave group velocity dispersion curves for propagation paths in northern Mexico. These paths were approximately orthogonal to boundaries of several different tectonic provinces including the Gulf of California, the

Notes on Obsidian Sources of the Southern Sierra Madre Occidental
Ancient Mesoamerica, 1993AbstractRecent fieldwork has identified a previously unknown obsidian source area in southern Zacatecas and northern Jalisco. Evidence of prehistoric use of surface gravel and nodule outcrops in the Huitzila-La Lobera source area includes raw-material extraction and the production of cores, large blade blanks, rough bifaces, and other artifacts ...

Bioclimatic belts of Sierra Madre Occidental (Mexico):A preliminary approach
International Journal of Geobotanical Research, 2013A bioclimatic synthesis of the Sierra Madre Occidental (SMO) based on the diagnosis of data from 159 meteorological stations, the floral and vegetation data collected in field surveys, and in the bibliographic revision. The considered area is above the altitude of 1800 m included in the physiographical province of SMO, which entirely belongs to ...

Some Scolytidae From the Sierra Madre Occidental in Mexico
The Canadian Entomologist, 1966AbstractA survey of the insect fauna in a part of the Sierra Madre Occidental in Mexico was made in 1964 by a party of nine entomologists from the Canada Departments of Agriculture and Forestry. Approximately 50 species of Scolytidae in 20 genera were collected on this expedition and are listed with host relationships and distribution where possible. A

Post-Oligocene river incision, southern Sierra Madre Occidental, Mexico
Geomorphology, 2003The Sierra Madre Occidental of western Mexico consists of a granitic basement covered by Oligocene ignimbrites that define a reference surface from which to estimate late Cenozoic river incision. A 90-m-grid digital elevation model was used to characterize contemporary topography and interpolate the Late Oligocene surface of the ignimbrite plateau from

Tectonomagmatic Pulses and Multiphase Mineralization in the Sierra Madre Occidental, Mexico
2020The material covered over this six-day field trip explores the regional stratigraphy, tectonic setting, and mineral deposits of the central Sierra Madre Occidental and western part of the Mesa Central in Mexico. The course builds on similar field trips held in 1997, 2003, and 2014, adding updates of the geology based on new studies and opening of new ...
