Among the possibilities of the restoration of these areas, the revegetation with native species, the case was proposed the encenillo (Weinmannia tomentosa), the oak (Quercus humboldtii), the wax laurel (Myrica pubescens), the silver yarumo (Cecropia sp ). .), cinnamon (Hedyosmun bonplandianum). However, the chemical characteristics control system can not be used. Yeasts and the technique of controlled seed pregermination in two models in the plant, against Rhizoctonia sp., And Botrytis sp., Causing the first of decay in the seeds and the neck of the root and the second cause of the gray mold in leaves, stems flowers and fruits, in native as well as commercial species. In the evaluations in the plant of three isolates of Trichoderma and two of yeasts; an isolation of Trichoderma originated in a soil of the municipality of Tenjo (La Punta village) was chosen, due to the high biocontrol activity against Botrytis and Rhizoctonia, in the latter case in combination with the active seed pregermination technique. The use of this microorganism (Trichoderma-Tenjo) together with the pregermination, a viable strategy for the treatment of seeds of native plants, in order to be used in the processes of revegetation, in the Quebrada Grande Microbasin.Ítem Evaluación del estado sucesional de la ronda de la microcuenca alta de la Quebrada Grande, Municipio de San Antonio de Tequendama (Cundinamarca).(2014-11-14) Melo, Germán; García, Paulo; Valencia, Jesika; https://scienti.colciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001399896; https://scienti.colciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000295612; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001590213; https://scholar.google.es/citations?user=JtcrgI0AAAAJ&hl=es; https://scholar.google.es/citations?user=60GkRtsAAAAJ&hl=es; https://scienti.colciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000012251; orcid.org/0000-0003-4746-0920; orcid.org/0000-0003-4086-0489As a result of deforestation, pollution, degradation and fragmentation of the ecosystem of the upper reaches of Quebrada Grande Otálora 2013, was triggered regeneration processes (secondary succession) have tended not to recover pre-existing conditions, which also have required tens or hundreds of years and they affect not only the plants but the companion birds, besides introducing higher soil amendments (Margalef, 1995); It is noteworthy that depending on the intensity of the disturbance and the nature of the ecosystems which dominate the area, the succession has taken an unexpected turn reaching the lost generation of native species and high value ecosystems for the region. This board paper the problem of loss of native species and ecosystems in the round of the Upper Basin of the Quebrada Grande located in San Antonio del Tequendama, at first a taxonomic characterization of plant and wildlife species were some groups available today and they can do an ecological retrospective system before processes human intervention, so it became known as was the system before the episodes of disturbance and how this current condition can be modified through the replacement of species through time and space. The research contributed to the knowledge of wild birds found in this area, given the conserved areas and processed for future decision-making, particularly for micro Quebrada Grande. On the information obtained and the bibliographical support databases that were found in the area and / or similar ecosystems major vegetation species and birds of the upper watershed of the Quebrada Grande were determined, leading to generate the definition of ecosystem reference. The system was evaluated through their fundamental ecological relationships through the identification of key native species, this generated a stress reading posdisturbio round high watershed.Ítem Evaluación in planta de tres desinfectantes contra el moho gris (Botrytis cinerea Pers.:Fr.), y de seis fungicidas y tres biofungicidas fungicidas contra mildeo velloso (Peronospora sparsa) en rosa (Rosa spp.): Informe de avance(2016-10-25) García Murillo, Paulo Germán; Almenares Aragón, Jennifer Vannesa; Valencia González, Jesika Natali; Serrano, María; https://scienti.colciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000295612; https://scienti.colciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001590213; https://scholar.google.es/citations?user=60GkRtsAAAAJ&hl=es; https://scienti.colciencias.gov.co:8085/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000012251; https://orcid.org/0000-0003-4086-0489Gray mold is a cosmopolitan and limiting disease of the cultivation and postharvest of the rose in Colombia; The objective of this study was to establish an in vitro test to evaluate the compatibility of four fungicides with a Trichoderma isolate (USTA_Tri-004).

Three Macroinvertebrates samples and a litre water sample per each site were collected. Water samples for the following parameters: total organic carbon, nitrites, nitrates, sulphates and phosphates were analyzed at a certified laboratory. The following metrics were estimated: taxa composition, abundance, tolerance, Family Biotic Index, Margalef Index, Shannon-Weaver Index and Pielou Index. The FBI values for the water quality were consistent with those reported in the chemical analysis. Total organic carbon and phosphates presented very high values in the water of sites with fair, fairly poor, poor and very poor water quality; while the nitrites, nitrates and sulfates maintained their values well below the allowable values for human consumption in all sampling. These results suggested high level of anthropogenic impact in the subbasin and the main pollutants were the total organic carbon and phosphates.Ítem Estimación de la captura y almacenamiento de carbono y flujo de nutrientes en un sistema silvopastoril con Acacia decurrens y pasto Pennisetum clandestinum en el Municipio de Mosquera- Cundianamarca(2018-03-07) Artunduaga Ruíz, Carlos Mario; Huertas González, María Alexandra; https://scienti.colciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001412828; https://scienti.colciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001473374; https://scholar.google.es/citations?user=PBqgtLsAAAAJ&hl=es; https://scienti.colciencias.gov.co:8085/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000012251; https://orcid.org/0000-0002-7870-373X; https://orcid.org/0000-0002-4765-8569GHGs have been significantly affecting the environment, generating global warming associated with current climate change. Traditional cattle breeding is characterized by a significant impact in this regard, given the digestive physiology of ruminants. The silvopastoral systems SSP have been constituted as a viable alternative for the mitigation of the previously mentioned harmful effects. The potential mitigation impact of GHGs in these sustainable production systems can be determined by estimating the carbon capture and storage of tree species through the photosynthetic process. The experimental phase will be carried out in a lot with SSP located in the Agricultural Biotechnology Center of SENA in the Municipality of Mosquera. In the present work, we intend to estimate the amount of methane emitted by Holstein breeding calves in an SSP by using mathematic models proposed in the Guidelines for National Greenhouse Gas Inventories of the IPCC. In addition, the methane collected and stored At different planting densities of the woody species Acacia decurrens in association with the pasture Pennisetum clandestinum.

This work seeks to develop a new methodology that characterizes the dynamics of the housing index and allows to establish objective predictions of its dynamics, analyzing its fluctuations in analogy with probabilistic random walk, this is a theoretical probabilistic model with representations of random walks, which allows limit the dynamics and find predictive numerical values whitin certain ranges to determine the evolution of its dynamics. This methodology has allowed us to characterize the evolution of the annual dynamics of the number of infected by dengue in Colombia, as well as childhood obesity in the United States, achieving predictions of practical application in public health in both cases. Since the fluctuations of the housing index is an irregular and complex phenomenon, it can be studied from the Brownian movement. A prediction of the behavior of the housing index (IV) will be made from the previously developed methodology Rodríguez et al., And their values will be compared with the real values for specific time periods of records of the National Institute of Health, in order to confirm the predictive ability of the method.

The drying process will be carried out by means of solar dehydration, where an outdoor test will be carried out with cover and one without cover, in turn with three types of drying disposition height at 1 cm., 2 cm., And 3 cm., Of the raw material already minced, this in order to evaluate the best system for the dehydration of the raw materials mentioned above and compare these results with the dehydration processes, carried out with industrial and electrical dehydrators, thus comparing the effectiveness of the dehydration process with sunlight, which affects the final costs of the products to be obtained, such as flours and dehydrated fruits. In the elaboration of these processes, the community will have an active participation, at the same time that they will be trained through the development of workshops that seek to generate knowledge and skills in the production of products, entrepreneurship and business training. For the systematization of the primary information, tables will be used with the variables, of weight, loss of humidity and yield of the flour process, in addition the graphs will be used for a better understanding of the data obtained in the field, in turn it will be triangulated with the conceptual framework and state of the art in order to have the analysis of the results.Ítem Impacto sobre la calidad del agua y la fauna béntica de tres criaderos comerciales de trucha arco iris, Oncorhynchus mykiss, en el río Siecha, Guasca, Cundinamarca.(2019-12-15) González Acosta, Julio Alberto; Rosado Puccini, Rafael; Lugo Vargas, Ligia Giorgina; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000992267; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000618918; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000527459; https://scholar.google.com/citations?user=dYYGICwAAAAJ&hl=es; https://scholar.google.es/citations?user=1QxGJsYAAAAJ&hl=es; https://orcid.org/0000-0001-7669-2507; https://orcid.org/0000-0002-2560-8966; https://orcid.org/0000-0002-4371-6514Ítem Aplicación de los métodos de preferencias declaradas y reveladas para establecer el valor económico de los bienes y servicios ecosistemicos del parque nacional natural Tayrona (PNNT)(2020-07-27) Vargas Osorio, Juan José.; Barragán, Rafael.; Valbuena, Nicole Tatiana.; Roncancio, Edgar.; Moreno, María Alejandra.; Vásquez, Natalia.; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001402751; https://scholar.google.com/citations?user=tg9vauEAAAAJ&hl=es; https://orcid.org/0000-0003-1416-9467Ítem Evaluación de la eficiencia productiva de peces disco (symphysodon) en la etapa de alevinaje de la empresa mordiscos(2020-07-27) Moncaleano Gómez, Erika Marcela.; Riaño Sanchez, Andrea Lorena.; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001615893; https://scholar.google.es/citations?user=jF4ICaYAAAAJ&hl=es; https://scholar.google.es/citations?user=6qHDrI4AAAAJ&hl=esÍtem Zonificación Ecológica y Socioeconómica como aporte al proceso de planificación y gestión, en el marco del proceso de Ordenamiento, de la Cuenca Grande del Municipio de San Antonio del Tequendama, Departamento de Cundinamarca(2020-11-12) Sánchez Espinosa, Jorge Alberto; Mendoza Plazas, Yenny Beatriz; García Murillo, Paulo Germán; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000295612; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000397733; http://scienti.minciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000507725; https://scholar.google.es/citations?user=60GkRtsAAAAJ&hl=es; https://scholar.google.es/citations?hl=es&user=sdr5qUUAAAAJ; https://scholar.google.es/citations?hl=es&user=sijh19AAAAAJ; https://scienti.minciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000012251; https://orcid.org/0000-0003-4086-0489; https://orcid.org/0000-0002-6459-2485; https://orcid.org/0000-0001-8877-1560In order to create a holistic view and generate reliable and useful information for making specific decisions and set on the natural development of the use of space at Basin Gulch Grande, the Vice-Presidency for Open and Distance Education University of Santo Tomas , through studies of biophysical and socio-economic that provide the basic information for the design of policy planning and regulation of land use and resource protection as a contribution to the processes of land management of watersheds , Framed under a systemic approach to the integration where interdisciplinary watershed research facilitates a better understanding of their structure and function in terms you can define elements and relationships .

The man-plant relationship was generated at first as a source of food and later as a raw material in the construction of their homes, the manufacture of clothing, obtaining pigments and medicines. When agriculture is established, profound changes in customs, social organization and a symbiotic relationship are established between domesticated plant species and the human species. The human population currently maintains a sustained increase, which increases the nutritional demand and plant raw materials for the industry; which makes scientific knowledge of plant species necessary and obligatory, which allows the use of a sustainable production of food and raw materials for pharmaceutical, industrial and textile use; framed within an adequate environmental administration.Ítem Cultivo de orellanas(2021-03-19) García Murillo, Paulo Germán; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0 000295612; https://scholar.google.es/citations?user=60GkRtsAAAAJ&hl=es; https://scienti.minciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=000000000122 51; https://orcid.org/0000-0003-4086-0489The cultivation of the edible fungus Pleutotus ostreatus (orellanas) can be viable in the city of Bogotá, since it generates abundant plant residues rich as a source of nitrogen (legumes) and mainly wood chips and sawdust.

For the control of this agent, fungicides are used as the first line, some of them causing phenomena of resistance in this phytopathogen and generators of risks to human health and potential risk of environmental contamination. Taking into account this problem, the research and evaluation of halophilic bacteria with B. cinerea antagonistic activity is proposed in this research. The methodology to be developed in this research consists of two stages: (i) selection of a minimum concentration for the manifestation of symptoms and signs of gray mold at 6 ° C and 20 ° C and strawberry fruits; (Ii) isolation and characterization of halophilic microorganisms isolated from saline and thermal springs in Colombia, (iii) evaluation of antagonistic potential of halophilic strains isolated in an in-plant model of tomato fruit, both at 6 ° C In post-harvest conditions) and at temperatures of 20 ° C, (iv) evaluation of the resistance capacity of selected bacteria at different ranges in ultraviolet light, and (v) evaluation in combination with CaCl2 for control of gray mold at temperature Cooling (6 ° C). This study aims to obtain a collection of halophilic microorganisms, characterized phylogenetically and physiologically, that present a high antagonistic activity to be used as biological controllers of B. cinerea.
