This is due to its distinct dispersal ability, its propensity to infect a wide range of cacao cultivars, its adaptability to different ecological niches, and its high pathogenicity. To develop effective control strategies, a deeper understanding of its genetic diversity and functional capabilities is critical. The objective of this study was to perform a pangenomic analysis of 22 M. roreri genomes to gain insights into its genetic composition and potential functional properties.Ítem Identificación de los valores objeto de conservación de Reserva la Rivera, Filandia, Quindío(Universidad EAFIT, 2024) Gómez Tirado, Esteban; Giraldo Salazar , Santiago; Díaz Pulido, AngélicaConservation values (CVs) are a limited number of species, communities or ecosystems that are chosen to represent the biodiversity of a landscape or protected area. They are objectives because they can be pillars in the conservation of ecosystems and their biodiversity, can be monitored over time, and account for the fulfillment of the conservation objectives of a protected area. The new conservation figures based on areas and that are constituted from civil society also require the implementation of strategies and conservation plans focused on CV. Our attention is focused on Reserva La Rivera, located in the north of the department of Quindío and directly bordering the Otún Quimbaya Fauna and Flora Sanctuary, which is part of the buffer zone of Los Nevados National Natural Park. It is a private conservation project with 345 hectares distributed between forests in different stages of regeneration and grasslands, and is located in one of the most important biodiversity hotspots in the world, the tropical Andes. For this study, biotic inventories of birds, mammals, reptiles and amphibians were carried out, taking into account historical records, collected specimens and field sampling in Reserva La Rivera; 308 species of birds, 30 of mammals, 13 of reptiles and 9 of amphibians were recorded and the conservation values were prioritized according to five criteria: heterogeneity, area of distribution, vulnerability, function and socioeconomic value. Five species were selected as VOC, represented by three birds, one mammal and one reptile. This diversity reflects the richness of the study area, its importance in the objectives of other protected areas and the connectivity in its buffer zones.Ítem First Draft Assembly and Annotation of the Genome of the Cadmium-Resistant Fungus Talaromyces santanderensis HF05 using Oxford Nanopore Sequencing : First Steps Towards Understanding its Cadmium Resistance(Universidad EAFIT, 2024) Picon Cossio, Juan José; Correa Álvarez, JavierÍtem Detección molecular de endosimbiontes Cardinium y Microsporidia en insectos vectores de la subfamilia Phlobotominae provenientes de áreas de alta transmisión de leishmaniasis(Universidad EAFIT, 2024) Tobón Vélez , Juan Pablo; Moreno Herrera, Claudia XimenaÍtem Compared anatomy of the tadpoles of Hyalinobatrachium tatayoi Castroviejo-Fischer et al., 2007 and Teratohyla pulverata (Peters, 1873) (Anura: Centrolenidae)(Universidad EAFIT, 2024) Abreu-Acosta, Daniel; Arredondo Salgar, Juan CamiloÍtem Estudio longitudinal de la expresión de la proteína ACSL4 en modelo de ratón 3xTgAD de la Enfermedad de Alzheimer(Universidad EAFIT, 2024) Agudelo Castrillón, Sara Camila; Cardona-Gómez, Gloria PatriciaÍtem Sistematización del procesamiento de metadatos y datos taxonómicos de cámaras trampa para la generación y publicación de DwC(Universidad EAFIT, 2024) Grisales Betancur, Valentina; Serna González, Mauricio; Sánchez Giraldo, Camilo; Pérez Navarro, Valentina; Sánchez Giraldo, CamiloCamera traps are a widely used tool to study and monitor biodiversity, benefiting researchers as well as the community at large, including park rangers, nature reserve owners, and conservation stakeholders. These monitoring efforts generate large volumes of data of value to science, contributing to the understanding of biodiversity, especially mammals. However, the complexity associated with the processing and analysis of this information is evident, since it requires technical knowledge of taxonomy and format management skills, hindering its publication on platforms such as the Global Biodiversity Information Facility (GBIF) and the Biodiversity Information System (SIB Colombia). Recognizing the importance of disseminating camera trap data for biodiversity management, we propose a workflow in R for processing these data efficiently, without the need for in-depth taxonomic knowledge and automating the generation of the Darwin Core format (Dwc). In contrast to other tools available for biodiversity data processing, our proposal focuses on promoting and simplifying the publication of data by the academic community and non-academic actors, guaranteeing the technical quality of the data, the accuracy of the taxonomy used and reducing the time required to fill out forms for publication. To validate the most efficient management in terms of reducing the time spent in processing biodiversity data, a dataset obtained in El Globo Natural Reserve (Támesis, Antioquia) was used. From the results obtained in an experimental test with a total of 10 expert and non-expert volunteers, it is concluded that the implementation of the workflow allows a reduction in the time spent in data processing and the completion of the DwC format. In addition to speeding up the process, this automation reduces the workload and potentially reduces errors in completing the form.Ítem Caracterización de la diversidad fúngica asociada al complejo de marchitez del aguacate (cv.

This study evaluates the production of functional macromolecules in the microalgae strain Chlorella sorokiniana UTEX 1230 as a supplement for laying hens. Cell growth was examined in different culture media with stimulant clinker powder, evaluating the bromatological composition, exopolysaccharides, fatty acid profile and in vitro digestibility, as well as the cost of production. These preliminary analyses are key to the implementation of microalgae as a protein source in poultry feed and warrant further in vivo testing.Ítem Evaluación del medio de cultivo sobre la producción de macromoléculas funcionales en la cepa Chlorella sorokiniana UTEX 1230 como posible suplemento alimenticio para gallinas ponedoras(Universidad EAFIT, 2024-05-23) Múnera Betancourt, Amalia; Miranda Parra, Alejandra MaríaAlternative protein sources, specifically algae and microalgae, are considered as viable protein sources for the poultry industry. Currently, different species of algae are used in animal nutrition to replace soybean meal (SBM) due to their high content of protein, fatty acids, and the availability of vitamins, minerals and pigments. Determining the chemical and nutritional composition of a biological formulation, in addition to its digestibility, is the first step in evaluating its suitability for use in poultry feeds. The aim of this work is to evaluate different culture media in the production of functional macromolecules in the microalgae strain Chlorella sorokiniana UTEX 1230 as a possible feed supplement for laying hens. The cell growth of the microalgae was evaluated over time under different culture media and different levels of addition of the stimulant clinker powder, a product of the cement industry. The biomass obtained from this process was evaluated for its bromatological composition, exopolysaccharide content, fatty acid profile, and in vitro digestion using digestive enzymes from monogastric animals, in addition to an evaluation of its production cost. This evaluation represents a preliminary analysis to initially select the mode of production to implement these products as a protein source in poultry feed, and further in vivo testing is warranted.Ítem Formulación de una estrategia de conservación de orquídeas en una reserva natural de bosque alto andino(Universidad EAFIT, 2024) Patiño Baena, Sebastián; Martínez Aguillón, CamilaÍtem Evaluación del potencial del magnetismo ambiental como herramienta para el biomonitoreo de la calidad del aire en Medellín, usando las dos especies de briófitos más abundantes en la ciudad(Universidad EAFIT, 2024) García Arias, Mariana; Benavides Duque, Ana María; Duque Trujillo, José FernandoÍtem Cranial Morphology of the Andean Lizard genus Pholidobolus (Gymnophthalmidae : Cercosaurinae) in Northern Colombia(Universidad EAFIT, 2024) Lozano Arias, Juan Manuel; Garzón Franco, Esteban; Arredondo, Juan Camilo; Arredondo, Juan Camilo; Garzón Franco, EstebanÍtem Caracterización de criterios de muestreo de Megaptera novaeangliae en el hemisferio sur americano para la elección del modelado poblacional(Universidad EAFIT, 2024) Londoño Gallego, Juan Andrés; Catatño López, AlexandraThis paper focuses on characterizing the sampling criteria in population studies of humpback whales (Megaptera novaeangliae) in the American Southern Hemisphere and Southern Ocean, examining key aspects such as sampling periods, type of modeling, sampling employed, geographic region, and potential impacts on population study areas such as migration, abundance, and population estimation; with the objective of understanding the current status of the study of the species and identifying factors that influence population modeling and the establishment of appropriate management and conservation measures. The methodology included a systematic literature review following the PRISMA 2020 protocol, searching Scopus and PubMed and applying inclusion and exclusion criteria to select 67 articles published between 2010 and 2023. A matrix was constructed with bibliographic information characterizing each study according to type of sampling, temporal factor, modeling, geography and impact, identifying the most frequent data in each section. Finally, a decision tree was constructed based on the information in the matrix, suggesting the most appropriate type of model according to the data and methodology used in the population study, acting as a practical guide to facilitate the choice of the appropriate population modeling, considering sampling criteria and other relevant factors identified in the systematic review.Ítem Efectos del déficit de fósforo en plantas de maíz(Universidad EAFIT, 2024) Riascos Rubiano, Catalina; Gilchrist Ramelli, ElizabethÍtem Genomic insights into Pannus brasiliensis CCIBt3594 a freshwater Cyanobacterium from Pantanal, Brazil(Universidad EAFIT, 2023) Betancurt Botero, Natalia; de Fátima Fiore, Marli; Junior Machado, Mauricio
