Ítem Amphibia : estrategias para mejorar la resiliencia socioecológica en el asentamiento Antonio Nariño del borde urbano rural de la Ciénaga San Silvestre, Barrancabermeja (Santander)(Universidad EAFIT, 2021) Carvajal Urrea, Yasmín; Sepúlveda Delgado, Camilo Andrés; Benítez Pérez, Maira Isabel; Ramírez Hernández, Wilson ArielThis degree project deals with how to define, address, and propose alternatives to the problems of a community that is strongly linked to the San Silvestre swamp and the city of Barrancabermeja (Santander), which entails several challenges as it means defining and identifying a multidimensional problem in which a social and ecological system (disturbed by various factors that lead to a loss of socio-ecological resilience) is connected. For this purpose, the conceptual framework of the Intergovernmental Scientific-Regulatory Platform on Biodiversity and Ecosystem Services (IPBES) is adapted. It also implies understanding a community in which the artisanal fishing way of life predominates (Antonio Nariño settlement) and a biodiverse and amphibious territory traditionally segregated (urban-rural border of Barrancabermeja). Amphibia is understood as a process that includes understanding the territory as a socio-ecological system, with social and ecological attributes that must remain over time and be restored, including a previous valuation. It also proposes methods that allow involving the communities that inhabit it and the local knowledge in the decision-making process concerning their habitat and ways of life, whose ultimate goal is to propose Nature-based Solutions (SbN, in Spanish) to solve the multiple socio-ecological problems in which natural and social capitals are the main elements.Ítem Análisis del conflicto felino-humano en la Orinoquia(Universidad EAFIT, 2022) Barrera Pedraza, Laura Milena; Vargas Sáenz, Mario EnrriqueThe felines are in danger of extinction due to deforestation, pollution, the fragmentation of their habitat, hunting, illegal trafficking and conflicts with humans when they attack domestic animals just for survival, for this reason it is intended to publicize the origin, the causes of the conflict and the actions that public and private institutions have developed in different regions of the country, in order to mitigate the conflict and harmonize the coexistence between the productive sectors and nature. Likewise, with the aim of having a context of the current state of the feline-human conflict in the Orinoquia, an analysis of cases is carried out through the complaints reported to the environmental authority Corporinoquia, said analysis allowed to identify the execution of bad livestock practices on the part of the farmers, therefore, through a bibliographic review some management recommendations are given directed to the ranchers of the region. This document, in addition to being informative, aims to create and strengthen capacities in the community regarding the conservation of natural ecosystems, through the transmission of the importance of the conservation of felines in the Orinoquia; and the implementation of anti-predatory measures to harmonize the feline-human conflict and improve the productivity of the livestock and agricultural sector in the region. Finally, the story of a puma victim of the feline-human conflict is exposed, who was rescued from Tame, Arauca, under the premise of generating spaces for socialization of this conflict.Ítem Los Andes actuó como "elevador pasivo" en la diversificación de las ranas de cristal (Anura: Centrolenidae)(Universidad EAFIT, 2020) Rueda Isaza, Yehimy Xilena; Díaz Nieto, Juan Fernando; Barrientos Correa, Lucas SantiagoÍtem Bosque somos todos : un esquema para evaluar el potencial socioecológico del bosque seco tropical (bs-T) en el desarrollo integral en la provincia de Cartama(Universidad EAFIT, 2020) Gómez Salazar, María Cristina; Moreno Yepes, Daniela; Valencia Sepúlveda, Catalina; Mejía Rivera, Oscar AugustoÍtem Cambios en el uso del suelo y su incidencia en la concentración y deposición de nitrogenados en el modelo de química de transporte LOTOS-EUROS para el Valle de Aburrá(Universidad EAFIT, 2021) Sánchez Aguirre, Andrés Felipe; Zapata Correa, Juliana; Yarce Botero, Andrés; López Restrepo, SantiagoConservation in the new century presents a multitude of challenges that are growing. One of the main challenges is the change in land use because it generates many transformed spaces that are constantly expanding and negatively affect the atmosphere, climate, ecosystems, and human health. Consideration in the land cover or use changes, together with transport chemistry models, enables the analysis of posible causes and consequences of future atmospheric dynamics in various temporal or spatial scenarios. The objective is to evaluate the variables of NOy Dry Deposition and NOx Surface Concentration, predicted by the LOTOS-EUROS transport chemistry model, when subjected to different land-use scenarios of the Aburrá Valley, generating an approximation to evaluate and predict the consequences of cover changes on the atmospheric dynamics of nitrogen and its possible effect on the surrounding ecosystems. This study analyzes different perspectives from the implementation for a case study in the Aburrá Valley of a chemistry-transport models as an important urban planning tool.Ítem Coalescent-delimitation framework and ecogeographic patterns disentangle the species boundaries within the Neotropical mouse-opossums subgenus Marmosops(Universidad EAFIT, 2022) Carillo Restrepo, Jhan Carlos; Díaz Nieto, Juan FernandoThe Neotropics encompasses a wide range of biomes and habitat types that place it as one of the most important Earth's regions for understanding the prevalence of cryptic and unknown diversity. However, it has been shown that this region is one of the least represented in genetic data in the tree of life. Therefore, advancing intra and interspecific genetic revisions in this region represents a major scientific priority to reduce our ignorance of the planet's biodiversity. American marsupials of Marmosops subgenus are distributed in a wide variety of Neotropical habitats, so it is an attractive group to undertake studies on Neotropical diversification processes, but such research is hindered by the fact that we do not yet fully understand the species limits of some groups within the subgenus. Herein, we evaluate the evolutionary independence of 13 morphologically-cryptic mtDNA haplogroups within Marmosops that were identified by our previous single-locus species delimitation analyses. For this purpose, we analyzed a multi-locus dataset (12 unlinked nuclear loci and one mtDNA locus) in a Bayesian Multi-Species Coalescent framework implemented in BPP, combined with heuristic criterion (gdi) that incorporated the speciation-continuum process into species delimitation analyses, to further understand the genetic boundaries within this Neotropical mouse opossum’s clade. Our BPP analyses recovered each of the 13 haplogroups as independent evolutionary lineages. However, heuristic gdi showed that the tested lineages are across the entire spectrum of the speciation continuum, and that only seven lineages recognized by BPP correspond to “true” species. Three of these seven lineages are currently recognized as valid species, demonstrating the effectiveness of our study; while ecogeographic patterns information revealed that the remaining four lineages have promising information to be recognized as possible new species for science.Ítem Empresa Biocultural : lineamientos para la creación de empresas sociales desde la restauración ecológica en el Piedemonte Llanero(Universidad EAFIT, 2022) Maldonado Pino, Julian Alejandro; Santiago Rua, Santiago; Vargas Sáenz, Mario Enrique; Roldán Ortiz, Ana MaríaÍtem Estimación de la geodiversidad en el Parque Nacional Natural Puracé, en función de los servicios geosistémicos(Universidad EAFIT, 2022) Daza Muñoz, Maria Camila; Morales Cáceres, Juan Diego; Marín Cerón, Maria IsabelÍtem Exploración de posibles impactos ecológicos por deposición de nitrógeno reactivo sobre las comunidades de líquenes en ecosistemas de páramo(Universidad EAFIT, 2022) Fernández Restrepo, Fernando; Román Arboleda, David; Pinel Peláez, Nicolás; Jaramillo Ciro, María MargaritaÍtem 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 Identificación de posibles afectaciones de ecosistemas en Colombia ocasionadas por contaminantes atmosféricos derivados de atentados a la infraestructura petrolera(Universidad EAFIT, 2022) Arenas Manjarrés, Daniela; Pinel Peláez, Nicolás; Enríquez Delgado, SandraÍtem Monitoreo de las obras piloto de recarga artificial en el acuífero Morroa, departamento de Sucre, Colombia(Universidad Eafit, 2020) Navarro Mercado, José Luis; Jaramillo Uribe, MarcelaÍtem Nuestro territorio común : gobernanza y gestión sostenible en el borde urbano sur de la Ciénaga de la Virgen en Cartagena, Colombia(Universidad EAFIT, 2021) Madero Jirado, Maristella; Bello Gómez, LorenaÍtem Patrones de actividad de mamíferos medianos y grandes en un paisaje transformado de la región del Magdalena Medio, Antioquia, Colombia(Universidad EAFIT, 2023) Álvarez Arias, Juan David; Sánchez Giraldo, CamiloÍtem Respuesta paleobiogeográfica de los foraminíferos planctónicos ante la extinción masiva del límite Cretácico- Paleógeno(Universidad EAFIT, 2020) Hernández Espitia, Camila Alejandra; Mejía Rivera, Camilo; Cárdenas Rozo, Andrés LeonardoÍtem Retos y oportunidades para el desarrollo del pago por servicios ambientales en la provincia de Cartama(Universidad EAFIT, 2024) López Betancur, Sebastián; Sierra Vásquez, Sebastián; Gutiérrez Rúa, Juliana MaríaIn the development of this research, an exploration and analysis of Payment for Environmental Services (PES) is conducted as a potential tool to promote ecosystem conservation in the Cartama Province. Based on its location, regional importance, and ecosystem diversity, the Province could implement this mechanism. Starting from a literature review and the analysis of international references and enabling regulations in Colombia, criteria were established for the development of PES. This information was subsequently analyzed in the context of Cartama and validated through interviews with local stakeholders. The research results propose challenges and opportunities that can be considered when implementing PES in the Cartama Province, contributing to current discussions on sustainable development models for the territory. Additionally, a guide is proposed to facilitate practical measurement of the social return on investment for the three main stakeholder groups in PES development: communities, companies, and government.
