Race diversity in dryland maize (Zea mays L.) landraces from southern Nuevo León, Mexico

This study was done for reviewing the diversity and distribution of native maize grown at southern Nuevo León, Mexico, in 40 accessions collected in the area. Information obtained was on the production unit and on the ears traits, according to the CONABIO guidelines. In this area maize is usually grown during the Spring-Summer period, and using little technology, without fertilization or pest control. The 40 accessions correspond to seven races and seven interracial crosses. The most frequent maize races were Ratón and Cónico Norteño, especially in dry areas with little rain. Races Celaya, Tablilla de Ocho and Elotes Cónicos found in this study, had not been previously reported; but the Tabloncillo and Olotillo races that had previously been reported were no longer found. Three collections stood out for producing large ears with large kernels, thus having a high yield potential. Native maize harvested in dryland areas might offer advantages to be grown under harsh environments.Objective: To analyze the race diversity and geographic distribution of the native maize landraces currently cropped at southern Nuevo León, México. Design/Methodology/Approach: Data was obtained from 41 accessions which represent the commercial production in the dry land area, where fertilization and pest control are scarcely used. Landraces were classified according to the CONABIO guidelines for ear traits. Results: The measured accessions correspond to seven maize races and to seven interracial crosses. The two most frequent maize races were Ratón and Cónico Norteño, mostly located in the dry areas with less rain. Study Limitations/Implications: Three races, Celaya, Tablilla de Ocho and Elotes Cónicos, had not been previously reported; while two formerly reported races Tabloncillo and Olotillo, were no longer found. This study did not include the grain-colored accessions. Findings/Conclusions: Three collections stood out for producing large ears with large kernels, thus showing a high yield potential. The maize landraces harvested in dryland areas might offer advantages to be grown under harsh environments or be used as gene donors for drought tolerance

From Magma Source to Volcanic Sink Under Tagoro Volcano (El Hierro, Canary Islands): Petrologic, Geochemical and Physiographic Evolution of the 2011–2012 Submarine Eruption

Active volcanoes are key laboratories to carry out detailed research -and monitoring- about the history of magmas before, during and after eruptions. Tagoro, the submarine active volcano at El Hierro Island (Canary archipelago), is a highly favorable case to assess and monitor its daily ongoing behaviour, as well as to study the links between the processes of magma genesis occurring at depth and their derived eruptive events at the surface. In this interdisciplinary research we combine new results of classical petrology (petrography, geochemistry, and thermodynamics) on the volcanic products expelled by Tagoro during the 2011–2012 eruption, with a high-resolution (5 m grid) bathymetry model carried out during 2017, and recent data from magnetometry, to refine the current knowledge of this eruption. Our results mainly reveal (i) slight magma differentiation and mixing processes at c. 12 km depth during a continuous eruptive pulse; (ii) a similar magmatic evolution and residence times at depth between previous and 2011–2012 eruptions on the island; (iii) an insignificant interaction of external fluids with the magma at depth or within the ascent conduit; (iv) a present-day magnetometric anomaly under the Tagoro’s area; (v) a minimum volume estimate for the magma withdrawn from the plumbing system at depth.This research was possible thanks to: (i) the funds provided by the MINECO and FEDER through the project VULCANO I (CTM2012-36317) and the project VULCANA (Vulcana-IEO-2015-2017) funded by the Spanish Institute of Oceanography, both granted to E.F.-N., that provided the oceanographic instruments, cruise and samples; (ii) the funds provided by the MINECO and MEC grants (Spanish Government) to A.M.A.-V. through the programs EXPLORA-CIENCIA (CGL2014—61775-EXP; MINECO), José Castillejo (CAS14-00189; MEC), and Programa Propio mod. 1B—2019 (USAL).

A-V specially thanks all the colleagues and friends who made possible this research starting from the ones designing the oceanographic campaigns, to those sharing their work on the vessel’s deck and acoustic lab, or carrying out geochemical analysis, as well as the undergraduate and graduate students involved in the research (some developing their master and graduate theses at USAL, e.g. I.N. and N.G., respectively).

Emprendimiento social Bazar del Padre Cuéllar

El PAP del Bazar del Padre Cuéllar es un proyecto de aplicación profesional enfocado en la economía social, es decir un proyecto que busca la transformación social a través de la actividad económica. El propósito principal del Bazar es generar valor social en la comunidad y fungir como uno de los eslabones principales en la salud financiera del Albergue Ciudad de los Niños del Padre Cuéllar. Por ende, es de vital importancia diseñar un proyecto que favorezca su funcionamiento tanto social como económico, para así mejorar la economía de toda la organización y al mismo tiempo incrementar el valor social a través de un modelo que mejore la calidad de vida del segmento de mercado al que va dirigido. El Proyecto propuesto es el de la realización de un Bazar Ambulante en comunidades desfavorecidas de la Zona Metropolitana de Guadalajara, buscando generar valor social sin dejar a un lado la rentabilidad para el Albergue Ciudad de los Niños. El semestre actual representa la continuidad de más de dos años y medio con la organización. A lo largo de la historia de este PAP se han logrado cumplir cabalmente diversos objetivos que han ayudado a darle forma a este proyecto social y esta ocasión no fue la excepción. El objetivo principal fue el mejorar aspectos de calidad y la difusión del Bazar, mediante la realización de una campaña de publicidad y análisis al sistema operativo, brindando más formalidad y difusión a nuevas generaciones sobre la existencia y funcionamiento del Bazar. En el siguiente reporte se muestra tanto el proceso como los resultados del proyecto del Bazar del Padre Cuéllar, mostrando de forma constante las habilidades adquiridas por cada uno de los miembros del equipo

Reporte Final PAP Primavera 2020: Playas región costa sur, Mezcala y UMAS, gestión integral de residuos del Estado de Jalisco, incorrecta disposición de los residuos líquidos denominados vinazas,CONAFOR y SEMADET

El proyecto de aplicación personal sobre el cual versa el presente reporte tiene con objetivo ser un vínculo de observancia de procuración de justicia ambiental, de tal forma, que, mediante este, se busca que los alumnos se conviertan en actores activos de las problemáticas ambientales que se gestan tanto en el nivel local, estatal y nacional. Para lograr esto, el equipo de alumnos se conforma por estudiantes de diversas carreras universitarias con la finalidad de generar un dialogo interseccional que permita generar el conocimiento y los insumos suficientes para generar estrategias y soluciones a problemas complejos, siempre buscando tener como eje rector la justicia ambiental. Para lograr el propósito de que los alumnos conozcan, desarrollen y propongan soluciones es que se genera un proceso de colaboración con una diversidad de actores relacionados dentro de la sociedad, de esta forma, buscando que el análisis crítico de la problemática ambiental que aborda al estado de Jalisco y las posibles soluciones para el apoyo de dichos grupos vulnerables. Este proyecto de aplicación profesional busca adentrar a los alumnos desde tres perspectivas distintas como lo son la academia, el sector privado y la administración pública buscando con esto dar a conocer el contexto de la complejidad del Derecho Ambiental a través de su aplicación desde una visión de procuración de justicia y la justiciabilidad. Dando como resultado una experiencia en donde el contacto con distintos sectores de la población, la aplicación de los conocimientos adquiridos durante la carrera y el análisis crítico de la realidad de los conflictos ambientales desde una perspectiva Ignaciana den como resultado la ejecución de mecanismos de procuración de justicia sobre la problemática ambiental que vive nuestro estado.ITESO, A.C
