Exploraciones De Sondeo En Tuzapan, Veracruz: Materiales Y Cronología
María Rosa Avilez Moreno Exploraciones de sondeo en Tuzapan, Veracruz: materiales y cronología Resumen: Tuzapan fue la cabecera de un altépetl prehispánico ubicado en lo que hoy es el centro- norte de Veracruz y habría sido conquistado por los mexicanos durante sus incursiones hacia la costa del Golfo. Aun cuando no se menciona en la Matrícula de tributos, ni en el Códice Mendo- cino, las evidencias materiales confirman una ocupación en el Posclásico tardío, y hay referencias explícitas en documentos coloniales tempranos como la Suma de visitas o las Relaciones geográ- ficas. Incluso su glifo aparece representado en documentos más tardíos, como los lienzos de Tuxpan y de Tzoquetitlán, que presumiblemente hacen referencia a épocas más tempranas. En este artículo se exponen algunos avances en el conocimiento logrados por el proyecto arqueoló- gico en la cuenca del río Necaxa mediante su trabajo de campo y de gabinete. La excavación, el análisis de los materiales recuperados y los fechamientos efectuados determinaron algunas de las características culturales del sitio, su cronología, la secuencia de ocupación y algunos vínculos interculturales. Se describen los pozos de sondeo y los hallazgos realizados en cada uno de ellos; se esboza una tipología cerámica tentativa; se describen los materiales líticos, y se exponen los resultados de los fechamientos por paleomagnetismo y por radiocarbono. Palabras clave: Tuzapan, Golfo de México, tipos cerámicos, lítica, fechamientos. Abstract: Tuzapan was the head of a pre-Hispanic altepetl (city-state) located in what is today north-central Veracruz and it would have been conquered by the Mexicas during their incursions into the Gulf Coast. -
Central Region of the Sierra Madre Oriental Executive Summary
CLIMATE CHANGE ADAPTATION PROGRAMME FOR THE CENTRAL REGION OF THE SIERRA MADRE ORIENTAL EXECUTIVE SUMMARY Climate change poses a growing threat to Mexico’s ecosystems and communities. Cou- pled with climate variability and socio-economic factors, such as changes in land use, it has adverse effects on ecosystems and livelihoods in rural communities. Regional and local planning tools are therefore required to implement climate change adaptation and mitigation strategies. One example is the Central Region of the Sierra Madre Oriental mountain range (RCSMO, for its initials in Spanish), whose biodiversity-rich ecosystems are vulnerable to climate change. This has an impact on local communities, because their livelihoods depend pri- marily on the area’s natural resources. Hence it is vitally important to assess the resilience of the ecosystems and the ability of local communities to cope with the effects of climate change. In 2010, the National Commission of Natural Protected Areas (CONANP) responded by developing the Climate Change Strategy for Protected Areas (ECCAP). The Climate Change Adaptation Programme for the Central Region of the Sierra Madre Oriental (PACC-RCSMO) is an essential part of this project. The area of intervention is ap- proximately 2.15 million hectares, covering parts of the states of Tamaulipas, San Luis Po- tosí, Hidalgo, Puebla and Veracruz and portions of three major river basins� which drain into the Gulf of Mexico (Pánuco, San Fernando-Soto la Marina and northern Veracruz). Four natural protected areas (NPAs) were established in the RCSMO region. Three of them are federal NPAs and the fourth NPA is set to be declared. -

Our study aimed to evaluate the influence of seasonal variation on abundance of food resources and its effect on food selection of Xerospermophilus perotensis, an endemic species of ground squirrel in the Oriental Basin. Food selection behavior was recorded us- ing focal animal and continuous behavior sampling on a squirrel population inhabiting the grassland of a semi-arid area. The results show that their diet consisted of 6 plant species with significant differences in the time spent feeding on each plant species (X2 = 128.96; P = 0.01). The species with the highest feeding times included Scleropogon brevifolius (63.6 %), Verbena bipinnatifida (10.6 %) and Erigeron pubescens (10.5 %). These plant species had the highest percentage of vegetation cover and availability among seasons, but they were of low nutritional quality with regard to their protein/fiber ratio. -
Relative Clauses in Upper Necaxa Totonac: Local, Comparative, and Diachronic Perspectives1
Relative clauses in Upper Necaxa Totonac: Local, comparative, and diachronic perspectives1 David Beck University of Alberta Relativization strategies in the Totonacan family are largely undescribed, but detailed examination of one of the languages in the group, Upper Necaxa Totonac, reveals the presence of both externally- and internally-headed relative constructions. Also of note is the presence of relativizers that mark the animacy (human/non-human) of the head of the relative construction. This paper will show that, while phylogenetic evidence clearly demonstrates the relativizers to be descended diachronically from interrogative pronouns, they are best treated synchronically as complementizers, an analysis that follows directly from the presence of internally-headed relative constructions. Totonacan languages are spoken by approximately 240,000 people (INEGI 2010) living in an area of east-central Mexico centred on northern Puebla State and including adjacent parts of Hidalgo and Veracruz (see Figure 1; languages dealt with directly in this paper are shown in red). The family is generally considered an isolate; however, recent work has suggested links to Mixe-Zoque (Brown et al. 2011) and Chitimacha (Brown et al. 2014). Although the family has only recently become the object of serious investigation and description, the focus has been largely on its (admittedly spectacular) morphology; little has been written about syntax, and even less about the structure of complex clauses. Relative clauses in particular seem to have been given short shrift—which is surprising, given that from what we do know about them they seem to have some unusual properties. Consider the example in (1) from Upper Necaxa Totonac, the language for which we currently have the most data on relativization:2 1 I would like to thank my consultants in Patla and Chicontla, especially Porfirio Sampayo Macín and Longino Barragán Sampayo, for their help putting this paper together. -

Branney Department of Geology, University of Leicester, Leicester, LE17RH, UK ABSTRACT The eastern Trans-Mexican Volcanic Belt is characterized by a diversity of vol- canoes that are related to different processes and eruptive styles. The spectacular exposures of late Pleistocene and Holocene volcanism provide a unique opportunity to explore a variety of volcanic features and deposits that may be relevant for volca- nic hazard assessments within the area. This three-day fi eld guide describes selected representative examples of the regional volcanism showing volcanic features inclu- ding thick pyroclastic successions derived from the explosive activity of Los Humeros caldera volcano, caldera-rim effusions, alternating explosive and effusive activity of a vitrophyric rhyolite dome (Cerro Pizarro), and the eruptive activity of two composi- tionally contrasting maar volcanoes: Atexcac, a classic basaltic maar and Cerro Pinto, a rhyolitic tuff ring–dome complex. *[email protected] Carrasco-Núñez, G., Dávila-Harris, P., Riggs, N.R., Ort, M.H., Zimmer, B.W., Willcox, C.P., and Branney, M.J., 2012, Recent explosive volcanism at the eastern Trans-Mexican Volcanic Belt, in Aranda-Gómez, J.J., Tolson, G., and Molina-Garza, R.S., eds., The Southern Cordillera and Beyond: Geological Society of America Field Guide 25, p. -

Sección de Quetzalcóatl, 72960 Puebla, Puebla, México. [email protected] Abstract. The state of Puebla has little information about mammal presence and distribution. In a study to determine jaguar presence using camera traps and interviews, we obtained 16 new records of tepezcuincle (Cuniculus paca) in different vegetation types such as tropical rainforest and cloud forest, as well as in coffee plantations. The records prove that the species is widely spread along the Sierra Norte of Puebla, but the distribution of populations in the Sierra Negra is uncertain. Key words: Cuniculus paca, Puebla, Rio Necaxa drainage basin, Sierra Negra, Sierra Norte, tepezcuincle, lowland paca. Resumen. El estado de Puebla tiene poca información sobre presencia y distribución de mamíferos. En un estudio para determinar la presencia del jaguar, mediante cámaras y encuestas, logramos obtener 16 nuevos registros de tepezcuincle (Cuniculus paca) en diferentes tipos de vegetación como selvas medianas y bosque mesófilo de montaña,además de cafetales. Estos registros prueban que la especie se distribuye ampliamente a lo largo de la sierra Norte de Puebla; sin embargo, se desconoce la distribución de las poblaciones en la sierra Negra. -
Matching Development and Conservation in a Rural Community of Mexico
Matching development and conservation in a rural community of Mexico Gómez B. M.A., M.A. Mijangos C., E Salcedo S. P. Saldaña F. and S. Rodriguez T. Introduction At present, decisions made in the past in terms of natural protected areas or land for flora and fauna conservation are either limiting the development in some areas or fragmenting the biological corridors in others. Updated and geo-referenced information is needed to deal with both issues: conservation and development, and to allocate resources in an efficient manner. Nowadays, neither environmental authorities nor municipal agencies or inhabitants have enough, real data and criteria to stop civil works or to promote local or regional sustainable development. Nevertheless, during the preparation of EIS’s is evident that every time more governmental agencies are making available geo-referenced information (www.ine.gob.mx; www.conabio,gob.mx; www.conanp.gob.mx). This information is generally available at broad scales 1:250 000 (INEGI, INE, CONAGUA, 2007) with few examples at lower levels like micro-basin or municipalities. In order to reach opportune decisions and deal with governmental budget allocation in time, it is important to promote and improve the use of this information by local and municipal public agencies (Sotelo y Jurado, 2007). This paper describes an EIS case study for a drinking water project located in a former well preserved forest, now converted in the suburban area of a town with 37,000 inhabitants. Reviewing protected areas polygons and its significance for conservation and connectivity are needed to improve environmental protection and to promote development at local and regional levels. -

Eruptive Variations During the Emplacement of Cerro Pinto Dome Complex, Puebla, Mexico
ERUPTIVE VARIATIONS DURING THE EMPLACEMENT OF CERRO PINTO DOME COMPLEX, PUEBLA, MEXICO by Brian William Zimmer A Thesis Submitted in Partial Fulfillment Of the Requirements for the Degree of Master of Science In Geology Northern Arizona University May, 2007 Approved: ______________________________ Nancy R. Riggs, Ph.D., Chair ______________________________ Gerardo Carrasco-Nuñez Ph.D. ______________________________ Michael Ort Ph.D. ______________________________ Wendell Duffield Ph.D. ABSTRACT 1 ERUPTIVE VARIATIONS DURING THE EMPLACEMENT OF CERRO PINTO DOME COMPLEX, PUEBLA, MEXICO Brian William Zimmer Cerro Pinto is a Pleistocene rhyolite dome complex located in the eastern Trans-Mexican Volcanic Belt. The complex is composed of four tuff rings and four domes that were emplaced in three distinct eruptive stages marked by changes in vent location and eruptive character. During Stage I, vent clearing produced a 1.5 km diameter tuff ring that was then followed by emplacement of two domes of approximately the same volume (~ .2 km3). After a brief hiatus in activity, Stage II began with the explosive formation of a second tuff ring to the north of the original ring that was ~ 2.0 km in diameter. Subsequent Stage II eruptions produced two smaller tuff rings within the northern tuff ring as well as a small dome that was mostly destroyed by vulcanian eruptions. The final stage, Stage III, involved the emplacement of a final dome within the southern tuff ring. Cerro Pinto’s eruptive history includes sequences that follow simple rhyolite-dome models, in which a pyroclastic phase is followed immediately by effusive dome emplacement. Some aspects, however, such as the occurrence of explosive reactivation and explosive dome destruction, are not well documented in rhyolitic structures originating from small, isolated magma chambers. -
