Análisis del comportamiento de visitantes internos ante el desarrollo urbanístico y territorial del microcentro de San Salvador.

En El Salvador, las actividades de recreación forman parte fundamental del desarrollo social, cultural y sostenible, siendo el turismo un sector con alto potencial de crecimiento en el país. A lo largo de la historia del Microcentro de San Salvador ha sufrido transformaciones arquitectónicas, geográficas y culturales debido a fenómenos naturales y sociales. Para solventar la situación, se pusieron en marcha diferentes planes de ordenamiento municipal. El último fue ejecutado durante la administración de 2015-2018 donde se implementaron herramientas de marketing urbanístico y territorial con el objetivo de impulsar un desarrollo turístico, fomentando actividades culturales y de recreación tanto para visitantes internos y extranjeros. Esta reestructuración fomentó desarrollo económico, social y cultural; establecimiento de nuevos comercios, mayor número de actividades culturales, restauración y remodelación de áreas recreativas; la afluencia de los visitantes al Microcentro aumentó junto a la seguridad pública proporcionada por la alcaldía de San Salvador. Gracias a la investigación, se determinó que los visitantes siguen ciertos patrones de conductas reflejados en diferentes teorías de comportamiento. Los resultados señalan que la diferencia de los patrones conductuales entre cada variable radica en la prioridad de sus necesidades: a pesar de que ambos realizan las mismas actividades, comparten gustos y preferencias, es indiscutible que su orden dista de ser igual. Existen altas perspectivas por parte de visitantes internos del Microcentro de San Salvador hacia un continuo desarrollo cultural y económico de la zona

Implications of the Western Diet for Agricultural Production, Health and Climate Change

Our current eating habits affect not only our health but also the environment and agricultural production. Previous studies have shown the relationship between our eating habits and each of these three topics independently. Here we analyzed the links between health, agricultural production and environmental data together, using global databases. We found the Western diet—dominated by processed foods, refined sugar, fats and flours—has negative implications for all three. Increased production and consumption of sugar and refined grains over the last 40 years correlates with negative human health outcomes globally: an alarming increase in diseases such as diabetes, overweight and obesity. In addition to these health effects, the Western diet relies on methods of agricultural production that negatively impact ecosystems, increase the use of fossil fuels and boost greenhouse gas emissions (GHGe). Ancestral communities around the world consume a greater variety of plant and animal species (including insects) than Western urban populations, with positive health and environmental outcomes. Processed food, on the other hand, comes at a high environmental cost: it generates high GHGe, accelerates land-use change to support agriculture and intensive livestock activities, and requires huge amounts of water and agrochemicals. Changing the Western diet could substantially reduce diabetes, obesity, and GHGe. Consuming insects and a wider variety of plant species could improve health outcomes and reduce some of the environmental impacts of agricultural production

Residual Effects of Transgenic Cotton on the Intestinal Microbiota of <i>Dysdercus concinnus</i>

The interaction among plants, insects, and microbes (PIM) is a determinant factor for the assembly and functioning of natural and anthropic ecosystems. In agroecosystems, the relationships among PIM are based on the interacting taxa, environmental conditions, and agricultural management, including genetically modified (GM) organisms. Although evidence for the unintended effects of GM plants on non-target insects is increasingly robust, our knowledge remains limited regarding their impact on gut microbes and their repercussions on the host’s ecology, especially in the wild. In this study, we compared the gut microbial community of Dysdercus concinnus bugs collected on wild cotton (Gossypium hirsutum), with and without insecticidal transgenes (cry1ab/ac), in its center of origin and diversity. By sequencing the V4–V5 region of 16S rRNA, we show differences in the diversity, structure, and topology of D. concinnus gut microbial interactions between specimens foraging cotton plants with and without transgenes. Identifying unintended residual effects of genetic engineering in natural ecosystems will provide first-line knowledge for informed decision-making to manage genetic, ecological, and evolutionary resources. Thus, determining which organisms interact with GM plants and how is the first step toward conserving natural ecosystems with evidence of transgenic introgression

Genetic characterization of atypical Citrobacter freundii.

The ability of a bacterial population to survive in different niches, as well as in stressful and rapidly changing environmental conditions, depends greatly on its genetic content. To survive such fluctuating conditions, bacteria have evolved different mechanisms to modulate phenotypic variations and related strategies to produce high levels of genetic diversity. Laboratories working in microbiological diagnosis have shown that Citrobacter freundii is very versatile in its colony morphology, as well as in its biochemical, antigenic and pathogenic behaviours. This phenotypic versatility has made C. freundii difficult to identify and it is frequently confused with both Salmonella enterica and Escherichia coli. In order to determine the genomic events and to explain the mechanisms involved in this plasticity, six C. freundii isolates were selected from a phenotypic variation study. An I-CeuI genomic cleavage map was created and eight housekeeping genes, including 16S rRNA, were sequenced. In general, the results showed a range of both phenotypes and genotypes among the isolates with some revealing a greater similarity to C. freundii and some to S. enterica, while others were identified as phenotypic and genotypic intermediary states between the two species. The occurrence of these events in natural populations may have important implications for genomic diversification in bacterial evolution, especially when considering bacterial species boundaries. In addition, such events may have a profound impact on medical science in terms of treatment, course and outcomes of infectious diseases, evading the immune response, and understanding host-pathogen interactions
