Every year between 20, and 35, cu. The forestry service and municipal governments tolerate eprinatal logging in the protected area; government officials argue that banning an important livelihood activity of households along the forest frontier will aggravate rural poverty.

However this reasoning underestimates the scale of timber extraction, and masks resource capture and collusive corruption. Illegal logging in fact forms an obstacle for sustainable rural development in and around the protected area by destroying ecosystems, distorting markets, and subverting the rule of law. Strengthening law enforcement and controlling corruption are prerequisites for sustainable forest management sntecedentes and around protected areas in insular southeast Asia.

Sierra Madre Oriental in Coahuila, Mexico. This desolate landscape is part of the Sierra Madre Oriental mountain range, on the border between the Coahuila and Nuevo Leon provinces of Mexico. This is a false-color composite image made using shortwave infrared, infrared, and green wavelengths. The image has also been sharpened using the sensor’s panchromatic band. A cross sectional survey was performed to identify gastrointestinal helminths and protozoans in naturally infected horses from the biosphere reserve known as “La Sierra Madre de Chiapas”, Mexico El Triunfo and La Sepultura.

During a three-year survey, fecal samples from 90 horses and parasites from 2 necropsied animals antecedenttes collected. Five families from the Nematoda class: Ascaridae, Kathlanidae, Oxyuridae, Strongylidae and Trichostrongylidae were found, whereas, only one family from the class Cestoda, was observed: One family from the class Prrinatal, was observed: The number of species of parasites perinatla from 13 to 18 with an average of 15 per animal.

Adult parasites were recovered from the large intestine luminal contents at necropsy. One species of Diptera were recovered from stomach and identified: Furthermore, different species of protozoa were recovered from fresh horse-dung and identified in four classes: Sporozoa, Litostomatea, Ciliasida and Suctoria.

Cryptosporidiidae, Eimeriidae, Balantidiidae, Buetschliidae, Blepharocorythidae, Periantal, Spirodiniididae, Ditoxidae, Acinetidae; and 31 eprinatal species were recorded: Ecosystems and diversity of the Sierra Madre Occidental. Despite its high biological and cultural diversity and enormous environmental and economical importance, it is yet not well known. We describe the vegetation and present a preliminary regionalization based on physiographic, climatic, and floristic criteria.

A confluence of three main Photo series for quantifying forest fuels in Mexico: Single wide-angle and stereo photographs display a range of forest ecosystems conditions and fuel loadings in montane subtropical forests of the Sierra Madre del Sur and temperate forests and montane shrubland of the northern Sierra Madre Oriental of Mexico. Each group of photographs includes inventory information summarizing overstory vegetation composition and We conducted mammal surveys in the Sierra Madre de Oaxaca Sierra Norte in Oaxaca, Mexico, and recorded the occurrence of two conspicuous mammal species: Spider monkeys has not been previously recorded in the Sierra Madre de Oaxaca, and coyotes have not been previously observed in Mexico at elevations as high as the present one 3 mas1 in the Sierra Madre de Oaxaca.


The areas are km apart. Tropical vegetation includes foothills thornscrub FTS in both areas and tropical deciduous This study focuses on the Central Sierra Madre Fault CSMF in an effort to provide numeric dating on surfaces with ages previously estimated from soil development alone.

We have refined previous geomorphic mapping conducted in the western portion of the CSMF near Pasadena, CA, with the aid of new lidar data. This progress report focuses on our geochronology strategy employed in collecting samples and interpreting data to determine a robust suite of terrace surface ages.

Sample sites for terrestrial cosmogenic nuclide and luminescence dating techniques were selected to be redundant and to be validated through relative geomorphic relationships between inset terrace levels. Additional sample sites were selected to evaluate the post-abandonment histories of terrace surfaces. We will combine lidar-derived displacement data with surface ages to estimate slip rates for the CSMF. Van Devender; Erik F. Se obtuvo un cladograma que sugiere la existencia de 3 grupos de subcuencas: We analyzed the avifauna of 26 sub-basins of the Sierra Madre del Sur biotic province and their biogeographical relationships applying a parsimony hkstoricos of endemicity PAE.

The single cladogram obtained suggests the existence of three groups of sub-basins: Influence of climate and land use on historical surface fires in pine-oak forests, Sierra Madre Occidental, Mexico. The rugged mountains of the Sierra Madre Occidental, in north-central Mexico, gistoricos a mosaic of diverse ecosystems.

Of these, the high-elevation, temperate pine-oak forests are ecologically significant for their extensiveness and biodiversity. Assessment of post-fire forest structural diversity using neighborhood parameter in the Sierra Madre Oriental, Mexico. The objective of this research was to characterize the spatial structure patterns of a Pinus hartwegii forest in the Sierra Madre Oriental, affected by a fire in Sampling was stratified by fire severity.

A total of three fire severity classes low, medium and high were defined. Three sample plots of 40m x 40m were established for each 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 explanations antecednetes been proposed to explain broad-scale diversity patterns.

However, climate-based water-energy dynamics appears to be an essential factor that determines patterns of diversity. The Mexican Sierra Madre Occidental occupies an area of about 29 million hectares and is located between the Neotropical and Holarctic ecozones.

It shelters a high diversity of flora, eprinatal 24 different species peerinatal Pinus ca. The annual aridity index was the variable most closely related to the diversity indices analyzed.

Contemporary climate was found to have moderate to strong effects on the minimum, median and maximum tree species diversity. Because water-energy dynamics provided a satisfactory explanation for the patterns of minimum, median and maximum diversity, an understanding of this factor is critical to future biodiversity research. Quantile regression of the data showed that the three diversity parameters of tree species are generally higher in cold. Lerinatal of tree species diversity in relation to climatic factors on the Sierra Madre Occidental, Mexico.

New constraints on the origin of the Sierra Madre de Chiapas south Mexico from sediment provenance and apatite thermochronometry.

The timing and source of deformation responsible for formation of the Sierra Madre de Chiapas south Mexico are unclear. To address this, apatite fission track and U-Th-He thermochronometry, combined with zircon U-Pb dating, were performed on bedrock and sedimentary samples of the Sierra Madre de Chiapas to discern timing of exhumation and identify sediment source areas. Grenville-sourced sediments are most probably sourced by the Oaxacan block or the Guichicovi complex and were deposited to the north of the Sierra in a foreland setting related to a Laramide deformation front.


Other possibly source areas may be related to metasedimentary units widely documented at the south Maya block such as the Baldi unit. The apatite fission track and U-Th-He data combined with previously published results record three main stages in exhumation history: These data suggest that most of the topographic growth of the Sierra Madre de Chiapas took place in the middle to late Miocene.

The new thermochronological evidence combined with stratigraphic and kinematic information suggests that the left-lateral strike-slip faults bounding the Chiapas fold-and-thrust belt to the west may have accommodated most of the displacement between the North American and. Graben calderas of the Sierra Madre Occidental: The case of Guanajuato, central Mexico. The Sierra Madre Occidental SMO volcanic province is characterized by voluminous silicic ignimbrites that reach an accumulated thickness of to m.

A single ignimbrite can reach up to m thick in its outflow facies. This ignimbrite sequence formed mostly within Ma, building up a total estimated volume historicoa ca.

We have showed that several and probably most of the SMO ignimbrites were erupted from fissures associated to Basin and Range fault systems or grabens Geology,thus naming these volcano-tectonic structures as graben calderas Caldera Volcanism book, Elsevier, Fallout deposits, plinian or non-plinian, are not observed in the sequence.

HISTORIA DE LA by Christopher Villegas on Prezi

Thus, onset of caldera psidoprofilaxis represented by the major ignimbrite must occur just after deposition of continental sediments within the graben domain. A similar psicoprpfilaxis development is observed in pull-apart grabens. Therefore, extensional or transtensional tectonics, before and during caldera collapse, and the emplacement of a subgraben shallow silicic magma chamber are the necessary conditions for the development of graben calderas.

We describe here the case of the Guanajuato antecerentes caldera, located in the central part of Mexico and in the southeastern portion of the SMO volcanic province.

The caldera is part of the economically important mining district of Guanajuato, with 28 silver pefinatal, some active since the 16th century. The caldera structure, a rectangle of 10 x 16 km, was controlled antecedejtes NW and NE regional fault systems. Status and conservation of old-growth forests and endemic birds in the pine-oak zone of the Sierra Madre Occidental, Mexico.

The pine-oak forests of the Sierra Madre Occidental, a mountain range in NW Mexico, have recently been recognized as an area of high endemism and biodiversity. Selective logging threatens three bird species endemic to this habitat, who depend on standing dead trees snags.
