Blood, fire and fertility : human remains and ritual practices at the temple pyramid groups of Cantona, Puebla, Mexico

La ville préhispanique de Cantona, située dans la vallée d’Oriental dans l’état de Puebla au Mexique, atteignit sa première apogée culturelle entre 150 av. J.C. et 600/650 A.D. Durant cette période, des complexes cérémoniaux comprenant des groupes de pyramides-temples et des terrains de jeu de balle furent construits. Ces installations servirent au déroulement de nombreux rites au cours desquels les victimes de sacrifices étaient décapitées, démembrées, décharnées, écorchées, bouillies, brûlées et, dans certains cas, consommées. D’autres traitements du corps humain comportent l’inhumation d’individus en position assise et repliés sur eux-mêmes. Pour mieux comprendre le traitement mortuaire rituel des corps humains à Cantona, les découvertes faites sur place sont comparées aux données datant de la même époque obtenues dans trois régions voisines : la vallée de Mexico, Puebla-Tlaxcala et le golfe du Mexique. A partir de ces renseignements, on peut en déduire que la majorité des découvertes faites à Cantona sont les restes des dépouilles et offrandes provenant de rites destinés à la communication avec les dieux et à l’obtention de la fertilité, tandis que les dépouilles des individus en position assise appartiennent à des prêtres ou à des personnages religieux.

Generation and analysis of the 2005 land cover map for Mexico using 250m MODIS data

Land cover plays a key role in global to regional monitoring and modeling because it affects and is being affected by climate change and thus became one of the essential variables for climate change studies. National and international organizations require timely and accurate land cover information for reporting and management actions. The North American Land Change Monitoring System (NALCMS) is an international cooperation of organizations and entities of Canada, the United States, and Mexico to map land cover change of North America's changing environment. This paper presents the methodology to derive the land cover map of Mexico for the year 2005 which was integrated in the NALCMS continental map. Based on a time series of 250 m Moderate Resolution Imaging Spectroradiometer (MODIS) data and an extensive sample data base the complexity of the Mexican landscape required a specific approach to reflect land cover heterogeneity. To estimate the proportion of each land cover class for every pixel several decision tree classifications were combined to obtain class membership maps which were finally converted to a discrete map accompanied by a confidence estimate. The map yielded an overall accuracy of 82.5% (Kappa of 0.79) for pixels with at least 50% map confidence (71.3% of the data). An additional assessment with 780 randomly stratified samples and primary and alternative calls in the reference data to account for ambiguity indicated 83.4% overall accuracy (Kappa of 0.80). A high agreement of 83.6% for all pixels and 92.6% for pixels with a map confidence of more than 50% was found for the comparison between the land cover maps of 2005 and 2006. Further wall-to-wall comparisons to related land cover maps resulted in 56.6% agreement with the MODIS land cover product and a congruence of 49.5 with Globcover.

Estimating the number of ozone peaks in Mexico City using a non-homogeneous Poisson model

In this paper, we consider the problem of estimating the number of times an air quality standard is exceeded in a given period of time. A non-homogeneous Poisson model is proposed to analyse this issue. The rate at which the Poisson events occur is given by a rate function lambda(t), t >= 0. This rate function also depends on some parameters that need to be estimated. Two forms of lambda(t), t >= 0 are considered. One of them is of the Weibull form and the other is of the exponentiated-Weibull form. The parameters estimation is made using a Bayesian formulation based on the Gibbs sampling algorithm. The assignation of the prior distributions for the parameters is made in two stages. In the first stage, non-informative prior distributions are considered. Using the information provided by the first stage, more informative prior distributions are used in the second one. The theoretical development is applied to data provided by the monitoring network of Mexico City. The rate function that best fit the data varies according to the region of the city and/or threshold that is considered. In some cases the best fit is the Weibull form and in other cases the best option is the exponentiated-Weibull. Copyright (C) 2007 John Wiley & Sons, Ltd.

Experimental Infection of Contracaecum tipapillatum (Nematoda: Anisakinae) from Mexico in the Domestic Cat

Juveniles of Contracaecum multipapillatum infected the Mayan cichlid (Cichlasoma urophthalmus) and adults infected the olivaceous cormorant (Phalacrocorax olivaceus) and the great egret (Casmerodius albus) in the coastal lagoon at Celestun, State of Yucatan, Mexico. All are new host records, and, even though the geographic locality record of Mexico for the species has not been published, unidentified but presumably conspecific specimens have been reported from there. When juveniles of C. multipapillatum were fed to a kitten, but not rats, ducks, or chickens, they developed into adults. Measurements and morphological data are provided on the specimens from the kitten. Development of an avian ascaridoid in the intestine of a mammal increases the potential of this widespread species to infect other mammals, including humans.

Testing the Performance of Fourteen Native Tropical Tree Species in Two Abandoned Pastures of the Lacandon Rainforest Region of Chiapas, Mexico

The rainforest of Mexico has been degraded and severely fragmented, and urgently require restoration. However, the practice of restoration has been limited by the lack of species-specific data on survival and growth responses to local environmental variation. This study explores the differential performance of 14 wet tropical early-, mid- or late-successional tree species that were grown in two abandoned pastures with contrasting land-use histories. After 18 months, seedling survival and growth of at least 7 of the 14 tree species studied were significantly higher in the site with a much longer history of land use (site 2). Saplings of the three early-successional species showed exceptional growth rates. However, differences in performance were noted in relation to the differential soil properties between the experimental sites. Mid-successional species generally showed slow growth rates but high seedling survival, whereas late-successional species exhibited poor seedling survival at both the study sites. Stepwise linear regressions revealed that the species integrated response index combining survivorship and growth measurements, was influenced mostly by differences in soil pH between the two abandoned pastures. Our results suggest that local environmental variation among abandoned pastures of contrasting land-use histories influences sapling survival and growth. Furthermore, the similarity of responses among species with the same successional status allowed us to make some preliminary site and species-specific silvicultural recommendations. Future field experiments should extend the number of species and the range of environmental conditions to identify site generalists or more narrowly adapted species, that we would call sensitive.

(Table 1) Redox potential and chemical element contents in CaCO3 and amorphous silica free matter in surface layer bottom sediments of the Pacific Ocean from Hawaiian Islands to Mexico coast

Distribution of Fe, Mn, P, Ti, Cu, Ni, Co, V, Cr, W, Mo, and As in the surface sediment layer on the section from the Hawaiian Islands to the coast of Mexico (Mexico section) is studied. Contents of all studied elements increase from biogenic-terrigenous sediments off the coast of Mexico to pelagic red clays of the Northeast Basin, and more sharply for mobile elements - Mn, Mo, Cu, Ni, Co, and As. In near Hawaii sediments rich in coarsely fragmented volcanic-terrigenous and pyroclastic material of basaltic composition with high contents of Ti, Fe, V, Cr, W, and P, contents of these elements increase sharply, and contents of Mn, Mo, Ni, Co, and Cu for the same reason decrease sharply in comparison with red clay. Abnormally high contents of Mn, Mo, Cu, Ni, Co, and As in the upper layer of hemipelagic and transition sediments of the Mexico section result from diagenetic redistribution and their accumulation on the surface. Processes of diagenetic redistribution in hemipelagic and transition sediment mass of the Mexico section are more rapid than in similar sediments of the Japan section due lower sedimentation rates and higher initial concentrations of Mn. Basic similarity of element distribution regularities in sediments of Japan and Mexico sections is shown.

Analysis of the upcoming Modernisation of the Trade Pillar of the European Union-Mexico Global Agreement

Study for the EU Parliament co-authored by Rodrigo Polanco: The 1997 Global Agreement between the EC and its Member States and Mexico, together with the set of decisions taken in its framework, has been effective, and thus modifications of the agreement are mainly motivated by changes in the global landscape since it was first enacted. Therefore, broad considerations on how the European Union (EU) trade policy is shaped are extremely relevant for the upcoming negotiations with Mexico. In this context, the needs and expectations, both from the EU and Mexico, regarding any further agreements are examined, focusing in particular on areas beyond trade in goods and services such as procurement, investment, and regulatory cooperation. It is argued that the 'old' Association Agreements should be taken as models for any modifications, given their emphasis on EU-specific issues and their ability to accommodate the needs of Mexico in any deepened agreement.

An investigative and interpretive study, with paintings, drawings and prints, of "All Saints' Day" and "All Souls" Day" in Mexico

"In Mexico, the first two days of November are set aside each year for the commemoration of the dead. This fete, called All Saints' Day and All Souls' Day, is observed throughout the world; however, in Mexico, it is celebrated in a manner peculiar to that country and to the various localities within that country . This holiday is sanctioned by both government and church; and is celebrated by practically all Mexicans, whether they be Catholic, pagan, relilious or irreligious. These are the two days when that contrast which is the essence of Mexico becomes obvious: the "triste~alegria" (sad-happiness). During these days , art objects are abundant and arresting ; and religious ceremonies, rites and fiestas blossom forth! Urban and folk arts, in every field, find full expression at this time. The religious, social, political, and artistic manifestations of the holiday are not only stimulating in themselves, but are exciting as subjects for painting, drawings, prints, and any other form of artistic expression!"
