En Montevideo, los primeros antecedentes surgen en los 80, asociados al patrimonio, desarrollándose posteriormente intervenciones locales. Un ejemplo contemporáneo de este tipo de políticas es el Complejo Antel Arena. El presente trabajo propone analizar las transformaciones territoriales a partir del Complejo, abordando su proceso histórico, agentes urbanos actuales e involucrados en el desarrollo, y cambios del entorno. La metodología es cualitativa basada en la triangulación de técnicas. Utilizando revisión bibliográfica, observación y entrevista semiestructurada se reconstruyó la historia espacial, identificó los agentes urbanos involucrados, evidenciándose su importancia y articulación entre agentes estatales, y se caracterizó el parque. Finalmente, con datos censales e informes, se corroboraron procesos de transformación barriales, como recambio poblacional, valorización del suelo, e impactos en la movilidad. El estudio de transformaciones territoriales es esencial para una mirada holística sobre las formas contemporáneas de construir ciudad.; Revitalizations are one of the most important urban transformations in Latin America. In Montevideo, the first experiences appeared in the 80s, related to patrimony, occurring later interventions with a local approach. One contemporary example is the ‘Complejo Antel Arena’. The purpose of this research is to contribute to the knowledge of territorial transformations due to the Complex, analyzing its historical process, urban agents present and involved, and surroundings changes. The methodology is qualitative based on the triangulation of techniques. Through bibliographical revision, observation, and a semi-structured interview the history was reconstructed, and urban agents were identified, becoming evident its importance, and the articulation within state agents, and the park was characterized. Finally, with census data and reports, transformations in the neighborhood were corroborated, such as population turnover, land value and mobility. The study of territorial transformations its essential for a holistic view on the contemporary ways of constructing the city.

It is necessary to identify the response strategies of producers that shape their resilience and their relationship with Agroecology. The objective of this study was to evaluate the resilience levels of fruit producers in southern Uruguay through the Holistic Risk Index (IHR), which combines indicators of threat, vulnerability and responsiveness, and the analysis of the relationship between its components. The average IHR was low and the values were similar among producers. Resilience levels were medium to high. Threats were mainly climatic and vulnerability responds mainly to economic factors. The responsiveness is linked to experience, knowledge and intergenerational transmission of knowledge.; La fruticultura en Uruguay enfrenta el desafío de mantener la producción de alimentos y promover la sustentabilidad en un contexto de disminución del número de productores e incertidumbre creciente. Se requiere identificar las estrategias de respuesta de los productores que configuran su resiliencia y su relación con la Agroecología. El objetivo del trabajo fue evaluar los niveles de resiliencia de productores frutícolas del sur de Uruguay a través del Índice Holístico de Riesgo (IHR) que combina amenaza, vulnerabilidad y capacidad de respuesta y el análisis de la relación entre sus componentes. El IHR promedio fue bajo y los valores similares entre productores. Los niveles de resiliencia fueron medio a alto. Las amenazas fueron fundamentalmente climáticas y la vulnerabilidad responde principalmente a factores económicos. La capacidad de respuesta se vincula con la experiencia, el conocimiento y la trasmisión intergeneracional de saberes.

However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem,we digitized the Smithsonian palynological collection using both light and confocal microscopy. We digitized the pollen of 12,000 species and took 40 million photos. Our image library will support a wide array of applications, including environmental monitoring, public health, biodiversity studies, paleoclimate, and the analysis of land-scape changes across spatial and temporal scales. It will also aid in geological correlations used in water exploration and in hydrocarbon storage/production.Summary: Palynology is a century-old practice, contributing data to various fields, from geology to medicine and forensics. Palynological analyses are highly time-consuming and involve visually finding, identifying, and counting thousands of palynomorph grains on microscope slides. These analyses are especially challenging in high-diversity tropical settings. Fortunately, the development of deep learning and the capability to digitize entire microscope slides are allowing palynology to enter a new era. Foundational to this transformation is building solid digital collections that can be achieved by digitizing botanical collections. We are digitizing the Smithsonian palynological collections, which contain 18,000 species, most of which are Neotropical taxa in the Graham Pollen Collection. This digital product consists of high-resolution images of different types transmitted light, differential interference contrast, and optical superresolution (Airyscan) which will be freely available and lay the groundwork for training deep-learning models and applying novel image analysis to palynomorph morphology. Image quality matters, so we outline the best practices we have developed throughout the years of imaging and experimentation. High-resolution imaging of palynological collections holds the key to unraveling the full potential that the study of pollen and spores can offer.

P.; de Mello e Sousa, Silvia Helena; Bonetti, Carla; Burone, Leticia; Belart, Pierre; Duleba, Wania; Francescangeli, Fabio; Frontalini, Fabrizio; Laut, Lazaro; Raposo, Débora S.; Rodrigues, André R.; Trevisan Disaró, Sibelle; Pupo, Daniel Vicente; Damasceno, Fabrício Leandro; Pavard, Jean-Charles; Alves Martins, Maria Virgínia Resumen: This study represents the first attempt to determine the indicator values of benthic foraminiferal species in Brazilian transitional waters. It also uses a regionally adapted species list to explore the potential application of Foram-AMBI, a biotic index for ecological quality. To test this, we assigned 95 living (rose-bengal-stained) benthic foraminiferal species into five ecological groups (EGs), based on the weighted-averaging (WA) optimum and tolerance to the total organic carbon (TOC) contents. Selected and published regional studies were used as the database, while independent Brazilian datasets from Sepetiba Bay and Guanabara Bay – the most polluted regions – were used to validate the ecological group assignments through Foram-AMBI. Furthermore, ecological quality status (EcoQS) criteria adapted to Brazil were developed for Foram-AMBI. The index accurately reflects the degraded environmental conditions in these two ecosystems, with moderate to poor ecological quality status in the most polluted areas. This was further confirmed by significant correlations between Foram-AMBI and TOC in both bays. This study highlights the importance of developing regional species lists and EcoQS criteria for Foram-AMBI, as the accuracy of the Brazilian list was better than that of the European list. While further research across broader pollution gradients is needed, our findings confirm the suitability and reliability of benthic foraminifera as biological indicators for assessing environmental quality in transitional waters.
