Ítem Estudio del género Graphis en el bosque seco tropical del municipio de Girardot- Cundinamarca, Colombia, como modelo de análisis de pérdida de biodiversidad por cambio climático(Universidad Distrital Francisco José de Caldas) Lara Rojas , Carlos Estiven; Gutiérrez Sarmiento , Martha Cecilia; Gutiérrez Sarmiento, Martha Cecilia [0000-0001-8077-4329]This study documented the diversity of the genus Graphis in three areas of the Tropical Dry Forest (TDF) in the municipality of Girardot, Cundinamarca, combining traditional sampling methods (Sipman, 1996) with species distribution modeling under future high-pollution climate scenarios. Given the high threat faced by TDFs due to deforestation and fragmentation, detailed information about their biodiversity is crucial for conservation. The results revealed three species new to science: Graphis epigraphis, Graphis maryae, and Graphis girardotensis. The methodology included the establishment of sampling areas, collection, identification, and deposition of specimens in the UDBC Herbarium – Non-Vascular Section. Among the reported species of the genus, higher diversity was observed between the Eastern and Western Cordilleras, in contrast with lower diversity in the Orinoquía region (Colombian Llanos), which is attributed to the scarcity of records in the latter. Alpha diversity indices suggested high diversity in lowland areas, with dominance by a few species (Simpson index), while beta diversity indices revealed considerable differentiation among Graphis communities across the sampling zones. The potential distribution modeling, conducted using the Wallace software, occurrence data, and climatic variables from WorldClim under the Maxent algorithm and the SSP 5-8.5 (2021–2040) climate scenario from the ACCESS-CM2 model (high emissions), showed an increase in the presence of Graphis anfractuosa towards higher elevations of the mountain ranges due to rising temperatures and droughts. G. caesiella and G. furcata showed trends of expansion towards the Llanos and the Middle Magdalena Valley, respectively. The lack of data prevented modeling for other species. The increase in presence at higher elevations raises questions about the effects of climate change on lichen communities and the potential loss through the turnover of species less tolerant to these environmental variables. This research georeferenced Graphis species in Girardot for the first time and developed an (unpublished) field guide including morphological, chemical, and spore information to facilitate the identification and recording of species. It concludes with the need to expand studies on TDF diversity before climate change significantly reshapes these areas, as highlighted by the discovery of three new species that demonstrate the still unknown high diversity.Ítem Propuesta pedagógica mediante el dialogo para el reconocimiento de la biodiversidad local por parte de los estudiantes de una escuela rural, Magdalena–Colombia(Universidad Distrital Francisco José de Caldas.) Estupiñan Sánchez, Lady; Ruiz Pacheco, Nelly JanethThis project, stemming from the "Viva la Escuela" program, proposes a dialogue-based pedagogy to foster recognition and appreciation of local biodiversity among students at a rural school in Magdalena, Colombia. Recognizing the impact of educational disparities, socio-environmental challenges, the pandemic, and social conflict on these communities, the initiative seeks to strengthen cultural and environmental identity through participatory activities that connect students with their local context and ancestral knowledge. The methodology prioritizes dialogical learning, promoting egalitarian interactions that value diversity and intercultural respect, and leverages both educational materials and human resources (teachers, students, and community members). Ultimately, the project aims to cultivate a sense of belonging and environmental stewardship by constructing knowledge through experience and intercultural dialogue.Ítem Reconocimiento de las problemáticas ambientales en las zonas de crecimiento urbano en Zipaquira(Universidad Distrital Francisco José de Caldas) Bernal Useche , Dawer Duvan; Daza Ardila, Diana del Socorro; Daza Ardila, Diana del Socorro [ 0000-0002-6043-2230 ]This paper addresses the recognition of environmental problems in urban growth areas of Zipaquirá, Colombia. This paper focuses on the perception and level of territorial ownership held by 8th grade students at the British School of Zipaquirá, in relation to the environmental problems arising from urban growth in their municipality. A Participatory Action Research (PAR) approach was used to engage students in the identification, analysis, and search for solutions to these local environmental problems, promoting greater student ownership of their territory, as evidenced by an increase in their knowledge of local environmental problems, a greater understanding of the causes and consequences of these problems, a greater ability to identify solutions and propose concrete actions, and a positive change in their attitudes and behaviors toward the environment.Ítem “¿Qué efectos tiene la aplicación de técnicas de Aikido arte marcial japonés en el aprendizaje de conceptos de biomecánica, ergonomía, higiene postural y lenguaje kinésico, con estudiantes de Licenciatura en Biología de la Universidad Distrital Francisco José de Caldas?”(Universidad Distrital Francisco José de Caldas) Sánchez Castañeda, Gottffied Alexis; Venegas Segura, Andrés Arturo; Venegas Segura, Andrés Arturo [0000-0001-8065-5696]This undergraduate project in the Biology Education program explored the intersection between Aikido, a traditional Japanese martial art, and its application in teaching concepts related to ergonomics, postural hygiene, and kinesic (non-verbal) communication. Through five practical workshops, Biology Education students experienced noticeable improvements in body awareness and non-verbal communication skills, while gaining an understanding of the health benefits associated with proper posture. Survey data revealed a significant increase in students’ knowledge—from no prior understanding to a deeper grasp of the topics covered. The findings support the recommendation to implement educational programs that integrate these concepts into the biology curriculum to enhance student training. The theoretical framework highlights the meaning of Aikido—from the Japanese components “Ai” (harmony), “Ki” (vital energy), and “Do” (path)—interpreted as “the path of harmonizing vital energy.” The study posits that Aikido can improve postural hygiene and mental health by promoting self-awareness, self-esteem, and cognitive relaxation. Key concepts such as body posture, biomechanics, center of mass, torque, and active breaks were discussed. The methodology involved hands-on Aikido workshops used as a pedagogical tool to teach and reinforce core principles in Biomechanics, Ergonomics, Postural Hygiene, and Kinesic Communication. Students participated in physical exercises and group reflections, enabling a more comprehensive and experiential understanding of the material. Pre- and post-intervention surveys showed a significant increase in awareness and knowledge regarding the importance of proper posture and its effects on health and communication. The study concludes that Aikido is an effective educational strategy for enhancing postural habits and self-esteem. Moreover, it demonstrates that martial arts practice contributes not only to physical well-being and posture correction but also to improved mental health and self-confidence. Consequently, the inclusion of martial arts-based programs that integrate Biomechanics and Ergonomics is recommended for the training of future biology educators, promoting a holistic approach to education and professional development. In summary, this research demonstrates that Aikido can serve as a valuable educational tool, offering benefits that extend beyond martial practice and significantly support the personal and professional growth of Biology Education students.Ítem Hilos de la naturaleza: Catálogo de especies productoras de fibras del Jardín Botánico José Celestino Mutis de Bogotá(Universidad Distrital Francisco José de Caldas) Origua Méndez, Derly Camila; Giraldo Quintero, Gustavo; Giraldo Quintero, Gustavo [ 0000-0003-3573-4154 ]This document aims to create a digital catalog titled “Hilos de la Naturaleza,” in which 25 species of fiber-producing plants found within the Tropicario (Useful Plants) of the Jardín Botánico José Celestino Mutis Botanical Garden in Bogotá are classified. The research highlights the ecological and cultural significance of natural fibers, presenting them as a sustainable alternative to synthetic and single-use materials. Through fieldwork and a bibliographic review, morphological, taxonomic, and traditional usage data were collected for each species and their respective products. Finally, the project culminates in the development of a visually appealing and accessible catalog that seeks to promote knowledge, conservation, and the responsible use of these natural resources.Ítem Cultivo sostenible y comercialización de Hericium erinaceus: un enfoque práctico a través del kit doméstico(Universidad Distrital Francisco José de Caldas) González Amado, Juan David; Árias Pineda , Julián Yesid; Árias Pineda, Julián Yesid [ 0000-0002-2399-7953 ]Hericium erinaceus, known as the lion's mane mushroom, is an edible and medicinal fungus widely used in traditional Oriental medicine. Its distinctive appearance, with long white spines cascading downward, has made it a mushroom of both gastronomic and therapeutic interest. It is attributed with antioxidant, anti-inflammatory, neuroprotective, anticancer, and immune-boosting properties, among others. For its cultivation, it requires specific conditions such as a suitable substrate, humidity and temperature control, and a regulated environment. Although it is popular in Asian cuisine, its consumption in the West remains limited. This entrepreneurial project aimed to promote its consumption in Colombia by spreading awareness of its health benefits, providing practical recipes, and developing and selling home-growing kits, offering a natural option to improve health.Ítem Implementación de un plan de capacitación sobre la norma ISO/IEC 17025:2017: requisitos y aplicaciones en los laboratorios de ensayo del Jardín Botánico de Bogotá José Celestino Mutis(Universidad Distrital Francisco José de Caldas) Carranza Umaña, Diana Valentina; Salazar Valencia, Natalia; Giraldo Quintero, Gustavo; Gildardo Quintero,Gustavo [ 0000-0003-3573-4154 ]; García Barreto, Germán Alberto (Catalogador)In Colombia, the certification/accreditation of laboratories is issued by entities such as IDEAM and ONAC, this process involves both technical and bureaucratic challenges and likewise obliges compliance with ISO/IEC 17025:2017; this establishes the technical and management requirements both nationally and internationally for testing laboratories. The Botanical Garden of Bogota José Celestino Mutis (JBBJCM) seeks accreditation of its laboratories so compliance with this standard is one of the primary steps for the process. Despite the relevance of the standard and its importance within the area, the implementation of activities for the understanding of all its components is a little explored challenge. This context motivated the creation of a training plan on the standard for the team of professionals in charge of developing the tests and documentation for accreditation. The training has key methodological elements such as pre- and post-training tests that recognize prior knowledge of the standard and contribute to a final balance that explores the strengths of the standard and possible improvements to the process; and five training sessions divided into the standard's numerals. The training covered five sessions in total and to evaluate the effectiveness of the process a paired t-test was used, which allowed comparing the pre and post test scores of the participants, thus demonstrating significant differences in the scores, suggesting that the training had a positive impact on the understanding of the standard, contributing to the progress towards the accreditation of the laboratory and accepting that the methodology used was effective in meeting the challenge, thus giving the green light to use similar processes within this and other management standards.Ítem Análisis bacteriológico de billetes de alta circulación de la Facultad de Ciencias y Educación de la Universidad Distrital Francisco José de Caldas(Universidad Distrital Francisco José de Caldas) Franco NegrIn, Anaís Sofía; García Caycedo, Luz Andrea; García Caycedo, Luz Andrea [ 0009-0006-6574-2277 ]; García Barreto, Germán Alberto (Catalogador)Cash is widely used around the world. In Colombia, at least 61% of transactions are made in cash and in the context of purchases made during the course of classes, this method also has preference. However, the composition of the Colombian Peso (COP), in 100% cotton fiber can lead to the transmission of diseases due to inadequate hygiene practices. In addition, the upgrowing bacterial resistance to antibiotics in recent years has become a significant public health concern. The objective of this research is the bacteriological analysis of high circulation banknotes in the Faculty of Science and Education of the Francisco José de Caldas District University, to correlate the isolated organisms with the denomination, physical condition of banknotes and antibiotic resistance. Banknotes were collected at the university and at the Bank of the Republic, and laboratory analyses were carried out using nutrient agar cultures, Baird-Parker agar, EMB agar and Mueller-Hinton agar, Gram staining, advanced colorimetric bacterial characterization with VITEK 2 Compact and antibiogram testing using amoxicillin 30μg. The results reported contamination in 97% of the samples analyzed, where bacteria belonging to the genera Aeromonas, Staphylococcus, Leuconostoc and Bacillus were identified, also showing resistant to amoxicillin and multidrug-resistant to various antibiotics, which may act as potential pathogens, especially in immunocompromised individuals. Such findings highlight how the use of cash in a university context can contribute to the spread of bacterial diseases, underlining the need for improved hygiene practices and control of antibiotic resistance.Ítem Caracterización morfológica e histológica de macrohongos presentes en la finca “La Franja”, vereda Vianicito, Vianí-Cundinamarca(Universidad Distrital Francisco José de Caldas) Martínez Martínez, Sofía; Tíjaro Orejuela, Mery Helen; Tíjaro Orejuela, Mery Helen [0000-0002-2519-066X]Macrofungi are eukaryotic organisms that develop visible fruiting bodies and are essential in diverse ecosystems due to their heterotrophic nutrition and their ability to act as saprophytes, parasites or symbiotics. These fungi are mainly classified into the Ascomycota and Basidiomycota divisions. The taxonomic identification of these species is facilitated by their morphological and histological characteristics, such as the description of the type and parts of the fruiting body and the septate or coenocytic hyphae. The objective of the present study is to carry out a morphological and histological characterization of the macrofungi present in the farm “La Franja”, located in the Vianicito village, municipality of Vianí, Cundinamarca, in an area of secondary forest of approximately 7 hectares. The research was carried out between April and November 2024 where 31 samples were collected, representing 27 species of macrofungi. The samples were processed in the neuroscience laboratory of the Universidad Distrital Francisco José de Caldas, where histological sections were made to examine the microscopic characteristics of the species. Morphological observations revealed a great diversity in the fruiting bodies, which adopted forms such as umbrella, bird's nest, stellate, cupuliform, among others. The fungi presented different types of hymenophores, including gasteroid, lamellar, porous and apothecial. Regarding their histology, septate hyphae were identified, however, they were mainly coenocytic, which vary between the two large groups of macrofungi studied: Ascomycota and Basidiomycota. Fungi of the Ascomycota division presented thinner hyphae without fibulae, while those of the Basidiomycota division showed thicker hyphae, with the presence of fibulae and an average diameter of 3 microns. It was also evidenced that the predominant substrates for the growth of these fungi were lignic and terricolous substrates, with gregarious and solitary habits observed in several species. This work provides detailed information on the morphological and histological characters of macrofungi in the region, an area little studied in mycological terms. From this study, a morphological and histological catalog was designed that includes photographs and detailed descriptions of the species identified. This catalog is a useful tool for the identification of macrofungi in the region and a significant contribution to the study of fungal biodiversity in Cundinamarca. In addition, this work highlights the importance of deepening the study of macrofungal species, contributing to the advancement of mycology in Colombia and promoting the conservation of knowledge about fungi. Additionally, the study highlights the need for further research and descriptions of macrofungi, especially in poorly explored areas, for the creation of precise taxonomic keys to facilitate species identification in the future.Ítem Estrategia didáctica para la enseñanza de la metamorfosis de insectos en una experiencia de realidad aumentada, usando como modelo el ciclo de vida de Leptophobia aripa(Universidad Francisco José De Caldas) Muñoz Cuadros, Tatiana Paola; García Martínez, Álvaro; García Martínez, Álvaro [0000-0002-3597-6252]Information and Communication Technologies (ICT) play a key role in the teaching-learning process, fostering the development of skills and promoting interactive, personalized learning. Among ICT, augmented reality (AR) stands out as a promising technology already used in many classrooms to enhance the educational process and take advantage of its benefits. On the other hand, in the field of Biology Didactics, challenges arise when attempting to apply didactic models based on scientific models, due to the fact that this science is constantly evolving, presenting difficulties related to the understanding of abstract concepts and the integration of theoretical and practical knowledge. In this way, ICT, especially AR, serves as a valuable tool for creating and reproducing models, as environments generated with this technology help students better understand biology and enhance their conceptual development. Therefore, this research improves the understanding of insect metamorphosis in secondary school students through the implementation of a didactic sequence, supported by augmented reality technology to explore the life cycle of the butterfly Leptophobia aripa. The research adopts a qualitative analysis approach and is developed at the Aquileo Parra educational institution, involving 65 seventh-grade students. For the didactic design, the proposal by García-Martínez et al. (2018) is used, and educational design research (EDR) is additionally incorporated to integrate technology into the development of the didactic unit (DU). In this way, it is evident that the didactic unit is effective in various aspects, as students are able to differentiate insects from other organisms and describe them effectively, demonstrating a clear understanding of the different types of metamorphosis and recognizing the various stages within the life cycle. Additionally, they understand the concept of ecological relationships and can mention some of them. Furthermore, an evolution in the skills to describe and explain is observed. As noted above, ICT are tools that enhance the teaching-learning process, as they not only facilitate the development of essential skills but also promote more interactive learning, effectively addressing the challenges inherent in teaching complex concepts such as insect metamorphosis.Ítem Aportes al estudio del género Micrurus a partir de los índices de conocimiento sobre biodiversidad aplicados a tres colecciones herpetológicas más representativas del país(Universidad Distrital Francisco José de Caldas) Díaz Castro, Ingry Johana; Giraldo Quintero, Gustavo; Gildardo Quintero, Gustavo [0000-0003-3573-4154 ]; Garcia Barreto, Germán Alberto (Catalogador)Biological collections are a very valuable source for the investigation of biological groups, since they are collected at a specific time and place, which offer a window to the past and allow planning for the future, where ophidian collections become relevant, not only for their medical importance but also for the ecology of snakes. Considering that the genus Micrurus is well known for its striking colored rings in most of its species, and the neurotoxicity of its venom, biological collections are one of the ways that make possible its ex situ study. Therefore, the biodiversity knowledge indexes are applied to the data published in SiB Colombia for 2024 of the three most representative biological collections in the country: Instituto de Ciencias Naturales -ICN-, Instituto Alexander von Humboldt -IAvH- and Museo de La Salle -MLS-. Demonstrating the low, but representative taxonomic diversity in each one, the lack and importance of curatorship, the possibilities of new records in the country, the departments and years of greatest collection, the deficit in research in protected areas, and the little importance given by the authorities to this biological group. Based on the results, it is proposed to optimize the quality of collection to improve diversity in the collections, taking into account inter-institutional links to avoid over-collecting; to encourage research, both on snakes and in collections; to promote research on snakes and collections; and to promote research in the field.Ítem Guía ilustrada de los principales visitantes florales en los cultivos de fresa, Sibaté, Cundinamarca(Universida Distrital Francisco José de Caldas) Fuentes Jiménez Jesús Manuel; García García, Alexander; García García, Alexander [ 0000-0001-9905-003X ]; Garcia Barreto, Germán Alberto (Catalogador)Raising awareness about the important role of pollinators in strawberry crops in Sibaté is of great environmental, economic and social relevance, since these insects are essential for the sustainability of strawberry agroecosystems. Given this situation, the need arises to generate educational and visual tools that promote knowledge and conservation of local biodiversity. The illustrated guide of floral visitors responds to this need, facilitating the recognition of the main pollinators and highlighting their ecological and agronomic importance. The guide was developed from a rigorous observation of insects collected in the study area, with optical techniques such as microscopes and specialized texts, to then begin the illustration process with digital tools such as Photoshop, in which the illustrations were made in the most detailed way in dorsal, lateral and frontal views. In total, 52 illustrations were developed, organized in a visually attractive structure that integrates information in the form of text in a concise manner, which makes up the respective infographics. Consequently, all the diagrams and infographics are put together to produce the guide, which consists of a total of 38 pages. In conclusion, by uniting fields such as science and art, this work is not only a visual resource that highlights the biodiversity of pollinators in Sibaté, but also a tool for scientific dissemination that promotes the recognition and conservation of the ecosystem services they provide.Ítem Macrohongos de hábito terrestre presentes en la finca "La Franja" Vianí CundinamarcaCortés Gamboa, Daniela; Merchán Mesa, Natalia; Tijaro Orejuela, Mery Helen; Tijaro Orejuela, Mery Helen [0000-0002-2519-066X]This study presents the preliminary results from the first year of evaluating the diversity of macrofungi at "La Franja" farm, Vianí, Cundinamarca. Twenty permanent plots were established to observe macrofungi in soil and organic matter substrates, with 40 morphotypes found in organic matter and 20 in soil. Specimens were collected, morphologically characterized, and recorded in a digital database along with photographic documentation. The results suggest that organic matter provides a more favorable environment for macrofungal diversity compared to soil. A field guide and an educational workshop for children were also designed to promote knowledge of macrofungi in the region. This study marks the beginning of a three-year project aimed at expanding the understanding of fungal diversity in the area.Ítem Científicas de las emociones: una propuesta para el desarrollo y transformación personal(Universidad Distrital Francisco José de Caldas) Ramírez Álava, Laura Daniela; García Reinel, Leyla Andrea; Venegas Segura, Andrés Arturo; García Reinel, Leyla Andrea [0009-0002-5451-6160]; Venegas Segura, Andrés Arturo [0000-0001-8065-5696]The main objective of this internship proposal is to promote the development of emotional intelligence in pregnant mothers, nursing mothers and adolescents emotional intelligence in pregnant and lactating mothers and adolescents between 13 and 20 years of age, who are Betania Foundation in Bogota.

The proposal focuses on intervening in this critical aspect by means of activities based on the Ruler method, which allow participants to identify, understand, express, regulate and transform their emotions, regulate and transform their emotions. In addition, it seeks to strengthen interpersonal skills such as empathy empathy and assertive communication, thus promoting healthier relationships between mothers and their children, as well as mothers and their children, as well as with their immediate environment.Ítem Establecimiento de la colección de referencia de mariposas Pronophilina (Nymphailidae: Satyrinae) en la colección de artrópodos y otros invertebrados CAUD-216 de la Universidad Distrital Francisco José de Caldas(Universidad Distrital Francisco José de Caldas) García Almanza, Nicol Alejandra; Mahecha Jiménez, Oscar Javier; Mahecha Jiménez,Oscar Javier [0000-0002-8682-0020]This work addresses the valuable role of biological collections as reservoirs of biodiversity in our country and their contribution to the conservation of natural history in Colombia. The internship was carried out in the collection of arthropods and other invertebrates CAUD-216 belonging to the Francisco José de Caldas District University, with the main objective of establishing a reference collection of butterflies of the Pronophilina subtribe. For this, curatorial processes, taxonomic determination and systematization were carried out. As a result, 96 specimens were incorporated which were determined up to the taxonomic category of species, including specimens such as Corades cybele, Pedaliodes phanzania, Steroma polyxo, among others, and endemic species such as Manerebia nevadensis and Pedaliodes symmachus. This work contributed to the creation of consultation spaces for the Pronophilina subtribe for future research and in standardization processes for digitalization in databases. Hence the importance of completing an internship in curating entomological material.Ítem Estudio de moscas comunes (Díptera: Muscomorpha) como visitantes florales en cultivos de fresa, Sibaté-CundinamarcaGuerrero Paz, Lorena; García García, Alexander; García García, Alexander [0000-0001-9905-003X]Colombia occupies one of the first places in fruit crops, among which the strawberry crop stands out with an area of 13,779 hectares planted. This makes it a crop of great economic and social importance, being one of the main horticultural products in Cundinamarca and Boyacá. Despite its importance, there is little study on floral visitors and alternative pollinators to Hymenoptera in this crop. The Muscomorpha infraorder comprises a wide diversity of flies with predominantly saprophagous, necrophagous and coprophagous feeding habits, however, their consumption of various floral resources is little known and studied, becoming an important group as floral visitors and potential pollinators in strawberry crops. The present study evaluated the effectiveness of flies of the Muscomorpha infraorder as pollinators in strawberry crops (Fragaria x ananassa) using a descriptive and quantitative approach. Through the analysis of ecological networks and pollen transport, significant patterns of interaction between flies and plants were identified. Delia cf platura stood out as the species with the highest frequency of visits and percentage of transported strawberry pollen (61.3%), evidencing its possible key role as a pollinator in this crop. Network metrics, such as connectance (36.1%) and nestedness (NODF: 66.8), showed a well-organized and hierarchical structure, where generalist species contribute to the stability of the system. This work highlights the importance of flies as floral visitors and their contribution to the maintenance of ecosystem services within strawberry crops.Ítem Una aproximación a la historia natural de las especies del género Bothrops (Viperidae ) en Colombia(Universidad Distrital Francisco José de Caldas) Díaz Atehortúa , Kevin; Mahecha Jiménez , Oscar Javier; Mahecha Jiménez ,Oscar Javier [0000-0002-8682-0020]The genus Bothrops (Viperidae) comprises several species of venomous snakes widely distributed in Colombia. They play a fundamental role in the ecosystems they inhabit, helping to control rodent populations and interacting with diverse species. This monograph presents an overview of the natural history of Bothrops in Colombia, addressing aspects such as their geographic distribution, habitat, ecology, behavior, diet, and reproduction. It also analyzes their morphological and physiological adaptations, which allow them to thrive in environments ranging from humid forests to dry regions.This work seeks to contribute to the knowledge of the genus Bothrops in Colombia, highlighting its ecological importance and the need to implement conservation and environmental education strategies.Ítem Conocimientos ecológicos, saberes y expresiones tradicionales: Construcción colectiva de un Inventario de fauna alrededor de la pesca artesanal, la recolección de piangua y la cacería de consumo localAbril Alfonso, Angie Nataly; Mahecha Jiménez, Óscar Javier; Robles Piñeros, JairoThe Colombian Pacific is a biodiverse region, not only for its biological richness, which sparks the interest of the scientific community, but also for its invaluable cultural heritage. This constitutes a fundamental component of the identity of the communities that protect, safeguard, and establish a constant dialogue with nature and the territory. Their traditional practices and knowledge reflect resource management, a deep relationship with ecosystems, and ecological interactions that energize life in mangroves, estuaries, the rainforest, and the sea. This research documented the ecological knowledge of local experts to construct an inventory that establishes a dialogue with scientific knowledge. It is hoped that this tool will contribute to management and conservation plans that include fishermen, piangüeras, and hunters. Fishing, piangüeo, and hunting activities were monitored for three months, adapting specific approaches to each practice. 80 species were identified for fishing, with 14 key species based on cultural consensus. In piangua harvesting, 34 species were recorded, and in hunting 19 species. In addition to 38 species of timber trees used as bait, and 66 species not directly related to the activity but part of the ecosystems and landscapes explored in each of the practices, for a total of 235 species. Documenting the practices and local ecological knowledge of hunting for local consumption represents a unique contribution. These findings highlight the importance of traditional knowledge in biodiversity conservation.Ítem Recambio altitudinal, estructura funcional y tasas de remoción del ensamble de escarabajos coprófagos (Coleoptera: Scarabaeidae) en la Sierra Nevada de Santa Marta, Magdalena, Colombia(Universidad Distrital Francisco José de Caldas) Palma Alfonso, Laura Valentina; García García, Alexander; Noriega, Jorge Ari; García García, Alexander [0000-0001-9905-003X]; Noriega, Jorge Ari [000-0003-1760-7020]Diversity gradients on mountains have great potential to improve our understanding of species distribution, richness patterns, and conservation, allowing us to generalize patterns of spatial dynamics associated with increasing altitude. Dung beetles are currently recognized as bioindicators that fulfill diverse functions in the ecosystem such as secondary seed dispersal, microorganism suppression, dung removal, and soil fertilization, among others. The Sierra Nevada de Santa Marta (SNSM) in Colombia is a peripheral mountain system with ideal conditions for studying altitudinal gradients. The present study evaluated the structure, composition, functional diversity, and dung removal rates of the dung beetle (Coleoptera: Scarabaeidae) assemblage along the northwestern slope of the SNSM. Sampling was carried out between December and January of 2020. Collections were made at seven stations, from 400 to 2830 m a.s.l. using pitfall traps placed in linear transects separated by 50 m from each other and approximately 400 m between each location. For the analyses of functional diversity, 12 morphological and ethological traits were measured. For the excrement removal rates, an experiment was carried out at the same heights for 24 hours before sampling. The structure and composition of the assemblage of dung beetles and their relationship with the altitudinal gradient were analyzed, taking into account biological and ecological aspects. For this, rarefaction curves, functional diversity indices, dissimilarity indices, non-metric multidimensional scaling, and a Mantel test were used. A total of 4792 specimens corresponding to 50 species, 18 genera, and 9 tribes were recorded. The richness, abundance, functional groups, and functional diversity markedly decrease with altitude, with significant differences between all localities. The structure and composition of the assemblage are represented by a marked pattern of replacement, with a marked difference between species from low, medium, and high zones. Regarding the removal rates of excrement, it was observed that they have a negative correlation with altitude as they decreased with the gradient. Additionally, it was found that at altitudes higher than 2032 m a.s.l. there is an abrupt drop in the removal of excrement, which is explained by the low richness, abundance, functional groups, and biomass found at these altitudes. Is confirmed that the SNSM is a system with a high species richness. Furthermore, the structure and composition of the dung beetle assemblage are characterized by several factors, including biogeographic, environmental, anthropogenic, and climate change aspects. It is essential that conservation plans must be structured, giving priority to the most diverse areas recorded here. It is recommended to evaluate functional processes and ecosystem services in other slopes of the SNSM and in other mountain systems, as well as to carry out studies using other groups of insects to find out how are structured and their contributions to the ecosystems. It is also essential to study different groups of vertebrates since they have an impact on the structure and composition of dung beetle assemblages.Ítem Análisis de las relaciones entre la fauna silvestre y la comunidad local de los humedales de Bogotá, para el desarrollo de estrategias de conservación y coexistencia(Universidad Distrital Francisco José de Caldas) Barón Ortegón, Caterin Julieth; Giraldo Quintero, Gustavo; Barón Ortegón, Caterin Julieth [0009-0006-6361-5960]; Giraldo Quintero, Gustavo [0000-0003-3573-4154]The wetlands of the Bogotá savannah and the Capital District belong to the Bogotá River basin and are part of the geographic system of the Cundiboyacense plateau. These ecosystems fulfill various functions that translate into essential ecosystem services for humanity, such as being habitat reservoirs for multiple species, mitigating the effects of climate change, regulating the water cycle of the city and constituting a fundamental pillar in the culture and spirituality of local communities. However, wetland ecosystems and the species that inhabit them currently face multiple threats derived from the climate crisis. Factors such as urbanization, environmental and water pollution, as well as habitat loss and fragmentation, seriously affect native, endemic and migratory species. In this context, the present research work aims to analyze the relationships between the inhabitants of Bogotá and the wildlife present in wetland ecosystems, in order to identify opportunities to promote conservation and coexistence strategies.The research was developed under a qualitative approach and the socio-critical paradigm, using the action-research methodology. Data collection was carried out through semi-structured interviews with 25 participants from communities near wetlands under the Ramsar category. The three-dimensional attitudinal model (cognitive, emotional and behavioral) was evaluated, considering two important phases: pre-intervention and post-intervention. The results reveal that the relationships of the participants with wetland ecosystems are multifaceted and are influenced by factors such as the social and environmental context, family history and developed sensitivity. Likewise, it is concluded that environmental education and the active participation of communities are fundamental for the conservation of ecosystems. The implementation of educational programs, together with the strengthening of local capacities, could foster greater ownership of wetlands and wildlife, ensuring their preservation.
