Between 2017 and 2018, a project on the development of technological alternatives for the sustainable production of greenhouse vegetables was implemented, with the aim of innovating the change in the horticultural production matrix to contribute to the reduction of the effect of climate change on the Puerto La Boca area, Jipijapa, Ecuador. In order to fulfill this objective, various activities were developed, articulating the three substantive axes of the State University of the South of Manabí, such as academia, research and linking, with the participation of the same university, the Agro-artisan Association of Puerto la Boca, the Decentralized Autonomous Government (DAG Municipal) and the private company. The substantive functions were articulated through the development of knowledge and technologies, the strengthening of the capacities of the producers, the realization of field days, as well as the systematic involvement of students (in research, pre-professional practices and bonding) and teachers in the activities The results achieved were the development of a technological offer such as tomato (Alambra, Itaipu and Baikor), pepper (Macantro and Tandara) and melon (Kapaz and Kazik) hybrids and methods [Integrated disease management (IDM) and management integrated vegetables (MIV)] more appropriate and timely as the development of a strategy based on four fundamental principles such as: a) The alternation of systemic and contact fungicides, b) non-application of the systemic fungicide more than three times c) the use of microorganisms (Bacillus and/or Trichoderma) that replace the contact fungicide and d) the reduction in the number of applications. These technologies and methodologies were made available to producers, so that they achieve better products and give them the opportunity to achieve business with better profitability margins in differentiated market niches (supermarkets); as well as the strengthening of the knowledge, attitudes and practices of the producers.

In this article, the contents of the niche-chambers situated within the perimeter wall of the Early Formative temple Tulán-54, located in the south-east of the Circumpuna Atacameña, are described and analyzed. The identification of animal bones, remains of lithic debris, of copper ore and ceramic fragments, as well as the burial of an adult, a metate offering and an entire Tilocalar-Los Morros type vessel, dated to 2640 BP (2765 to 2715 cal BP), indicate a relationship with the temple founding events. An infant burial found inside a sealed chamber of the ceremonial architecture was dated to 2600 BP (2750 to 2700 / 2630 to 2620 / 2560 to 2540 cal. BP), a period synchronous with the use of the niches. The nature and dating of the associated contexts are discussed in general and we reach the conclusion that the evidence found in the niches-chambers was part of the early performance practices of the temple.

In this paper I aim to study rap in Buenos Aires after 2001 observing the link between social and aesthetic aspects, from a perspective of ‘mediation’ and ‘worlds of art’. For this purpose, I analyze its origins in times of socio-economic crisis and the importance that the democratization of digital technology has had in its unraveling. I observe the development of diverse niches (related to class, generation or aesthetics cleavages), and a process of popularization related to freestyle-improvisation and trap as a sub-genre. As I will show, there is a diversification and a fast popularization associated with digitalization and self-management events, giving rise to home recording studios and video clips uploaded to the internet. Also, I point out the role of the State, big shows organizers, journalists, streaming agencies and major record labels. Finally, I propose that the internal differences in this music do not refer directly to homologies between social classes and different styles of rap.

La región de la Sierra Madre Oriental (SMO) en el estado de San Luis Potosí en México es considerada un sitio de relevancia para la conservación de la avifauna a nivel nacional. Por lo anterior, el objetivo de este estudio fue analizar la distribución geográfica de las aves en la zona para identificar las áreas con mayor concentración de la riqueza y evaluar su estado actual de conservación para fundamentar la necesidad de incrementar la superficie dedicada a las áreas naturales protegidas en el futuro. Se recolectó información proveniente de diversas bases de datos de colecciones y museos, además de realizar trabajo de campo en el periodo de enero 2009 a Mayo 2011. Se modelaron las distribuciones potenciales para 284 especies con el programa GARP y se elaboró un mapa de consenso para determinar la ubicación espacial de las áreas con condiciones ambientales para soportar el mayor número de especies. Finalmente, se evaluó la representatividad de las zonas dedicadas a la conservación para las aves. Se registraron 357 especies, de las cuales el 71.4% son residentes permanentes, 19% son migratorias de invierno y 3.9% residentes de verano. Del total, 41 especies son endémicas y 48 se encuentran en alguna categoría de riesgo; la mayor concentración de especies se presentó en las coberturas de bosques de encino, bosques mesófilos y selvas medianas y bajas caducifolias, en un intervalo altitudinal entre 100-1 500m con una más alta cantidad de nichos en la parte centro y hacia el sur y este de la región. Sólo el 10% de las zonas con alto potencial de número de especies está incluido como área de importancia para la conservación de las aves y el 3% del total de áreas potenciales está bajo alguna categoría estatal de protección; sin embargo, ninguna de las áreas tiene un plan de manejo que esté siendo aplicado y monitoreado. La información generada es importante para el desarrollo de propuestas de conservación para las aves en la región.The Sierra Madre Oriental region in the mexican state of San Luis Potosí is a relevant place for bird conservation at a country level. Therefore the main goal of this study was to analyze the geographic patterns of distribution and the conservation current state of the birds, to support the needs to expand the conservation areas in the future. Data was collected from various databases of zoological museums and collections, and field sampling methods conducted from January 2009 to May 2011. Potential distributions were modeled for 284 species using GARP software and then a map was developed to determine areas with favorable environmental characteristics for the distribution of species richness. Finally, the importance of conservation areas for the potential distribution of birds in the region was evaluated. A total of 359 species were recorded of which 71.4% are permanent residents, 19% are winter migrants and 4% are summer residents. From this total, 41 species were endemic, 47 were species at risk and 149 were neotropical migrants. The largest species richness correspond to oak forests, cloud forests, and tropical moist forests located at altitudes from 100m to 1 500m. Their potential distribution was concentrated towards the center and Southeast of the study area. Only 10% of areas with a high potential conservation was included in areas of priority for bird conservation (AICA) and just 3% of all potential areas were under some governmental category of protection. However, no conservation area has a management plan currently applied and monitored. The information generated is important for the development of management proposals for birds conservation in the region.
