Acciones interinstitucionales de vinculación y transferencia en el sector apícola y en la comunidad de Chaco y Corrientes

Este trabajo tiene como objetivo mostrar una serie de acciones de vinculación y trasferencia realizadas por un grupo interdisciplinario de profesionales. Estos pertenecen a FaCENA y FCA (UNNE), CONICET, INTA, e INTI. Incluye también una componente docente que busca formar, en tareas extensionistas, a los estudiantes de grado involucrados en los Proyectos del Programa “La Universidad en el Medio”. Tiene como finalidad dar a conocer la calidad de las mieles chaqueñas, principalmente las producidas en el Sitio Ramsar y localidades cercanas, asociada al origen floral para generar estrategias de implementación de valor agregado. Con el abordaje de diferentes problemáticas en la producción de miel, las acciones se realizaron con un grupo apicultores del Chaco, que pertenecen a dos cooperativas (COPAP [Margarita Belén] y Los Palmares [Basail]) y a una asociación apícola (Asociación de Productores Apícolas [Charadai]). Esta última no está incluida dentro del Sitio Ramsar. Todas las intervenciones apostaron al fortalecimiento del sector apícola de la región, mejorar la producción y aumentar el consumo de miel principalmente. Durante las jornadas de la “Semana de Miel”, se difundió sobre las propiedades naturales de los productos apícolas, además de fomentar el consumo de los productos primarios de las abejas y sus derivados. Se realizaron acciones con niños del nivel inicial promoviendo el consumo de miel, el cuidado y protección de las abejas como agentes polinizadores y conservadores de la biodiversidad

They belong to FaCENA and FCA (UNNE), CONICET, INTA, and INTI. It also includes a teaching component that attempts to train, in extensionist tasks, the undergra-duate students involved in the Projects of the Program “La Universidad en el Medio”. It looks to raise the quality of different types of honeys from Chaco, mainly those produced in Ramsar Site and nearby villages, associated with the floral origin to generate value-added implementation strategies. In order to approach different problems in honey production, the actions were carried out with a group of beekee-pers from Chaco, who belong to two cooperatives (COPAP [Margarita Belén] and “Los Palma-res” [Basail]) and a beekeeping association (Asociación de Productores Apícolas [Charadai]). The latter is not included within the Ramsar Site. All the interventions were focused on strengthening the region's beekeeping sector, improving production and increasing the consumption of honey in particular. During the events “Semana de la Miel”, the natural properties of beekeeping products were made public, as well as promoting the consumption of primary bee products and their derivatives. The actions were per-formed with children of the initial level promoting the consumption of honey, the care and protection of the bees as pollinating agents and biodiversity keepers.EEA Colonia BenitezFil: Salgado Laurenti, Cristina R.

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery

The monotypic Brazilian genus Diacrodon is a synonym of Borreria (Spermacoceae, Rubiaceae): morphological and molecular evidences

ABSTRACT Diacrodon is a monotypic genus of the tribe Spermacoceae (Rubiaceae), endemic to northeastern Brazil. Diacrodon compressus is frequently misidentified with a two lobed calyx species of Borreria, B. verticillata. Traditionally, in Spermacoceae the fruit type was considered a diagnostic character among the genera. In this sense, D. compressus presents a strongly compressed, one seeded and indehiscent fruit (vs. globose, two seeded and dehiscent fruit in B. verticillata). In this work, we address two objectives: evaluate the systematic position and determine the identity of Diacrodon in respect to other taxa. Molecular analyses using ITS and ETS indicate that D. compressus is strongly related to other species of Borreria. The morphological results revealed that D. compressus, despite of its type of fruit, is identical to Borreria in floral and palynological features. As conclusion, the new combination Borreria diacrodonta is made and a lectotype is designated. An updated description of the species and a key to the Borreria species with a two lobed calyx are provided. The distribution of B. diacrodonta is extended to Brazilian states Goiás and Minas Gerais, and Paraguay. By this taxonomical change it has become clear that the dehiscence of the fruits lack taxonomic value in the delimitation of Borreria

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
