Patterns of Tree Species Diversity in Relation to Climatic Factors on the Sierra Madre Occidental, Mexico
Biological diversity can be defined as variability among living organisms from all sources, including terrestrial organisms, marine and other aquatic ecosystems, and the ecological complexes which they are part of. This includes diversity within species, between species, and of ecosystems. Numerous diversity indices combine richness and evenness in a single expression, and several climate-based...
متن کاملA new species of bunchgrass lizard (Squamata: Phrynosomatidae) from the southern sky islands of the Sierra Madre Occidental, Mexico.
A new species of bunchgrass lizard in the Sceloporus scalaris group is described from the southern portion of the Sierra Madre Occidental in Mexico. The new species, Sceloporus aurantius sp. nov., was previously confused with S. brownorum but differs from this and all but one species within the S. scalaris group by a lack of blue belly patches in males.

متن کاملGeospatial Estimation of above Ground Forest Biomass in the Sierra Madre Occidental in the State of Durango, Mexico
Combined use of new geospatial techniques and non-parametric multivariate statistical methods enables monitoring and quantification of the biomass of large areas of forest ecosystems with acceptable reliability. The main objective of the present study was to estimate the aboveground forest biomass (AGB) in the Sierra Madre Occidental (SMO) in the state of Durango, Mexico, using the M5 model tre...
متن کاملDegree of Hybridization in Seed Stands of Pinus engelmannii Carr. In the Sierra Madre Occidental, Durango, Mexico
Hybridization is an important evolutionary force, because interspecific gene transfer can introduce more new genetic material than is directly generated by mutations. Pinus engelmannii Carr. is one of the nine most common pine species in the pine-oak forest ecoregion in the state of Durango, Mexico. This species is widely harvested for lumber and is also used in reforestation programmes. Inters...
متن کاملTrait analysis of the dentition of the Tarahumara Indians and Mestizos of the Sierra Madre Occidental, Mexico.
A new approach of trait analysis of the dentition is presented, based upon study of both deciduous and permanent dentitions of 114 Tarahumara Indians and 63 Mestizos of both sexes and ranging in age from 5 to 23 years. Molar cusp patterns and numbers, and odontometrics were analyzed and compared, and penetrance, sexual dimorphism, and concordance were investigated. To examine penetrance and exp...
