The contribution of nutrients to aquatic systems has been increasing simultaneously with the population increase. Urban and peri-urban nature reserves are fundamental spaces for the conservation of biological diversity and the preservation of a healthy environment. However, \nthe increase in human activities, the expansion of agricultural frontiers and urban growth, result in various environmental problems, such as eutrophication in their bodies of water, generated mainly by the contributions of Nitrogen (N) and Phosphorus (P), which are the nutrients most linked to the deterioration of aquatic ecosystems when they are in excess. \nThe Ecological Reserve El Renacer de la Laguna located in the Faculty of Veterinary Sciences (REFCV) of the UBA (FCV-UBA) and the San Antonio de Areco Parque Criollo (REPC) Nature Reserve, these are areas intended for environmental education and contact between the community and nature; however, they do not have management plans, which makes the comprehensive management of these protected areas difficult. The objective of this \nwork is to evaluate the contributions of N and P, and the degree of eutrophication of the lagoons of these two urban nature reserves, to prepare guidelines for the development of a future management plan for these water bodies. \nThe main results show that the values of Nt estimated and Pt in the Renacer de la Laguna lagoon range from 10.53 to 123.64 mg/L and from ?0.001 to 0.24 mg/L seasonally, while in \nthe Parque Criollo lagoon they vary from 25.19 to 49.56 mg/L and from 0.23 to 0.59 mg/L, respectively. The values of the N:P estimated molar ratios in the studied lagoons vary significantly from winter to summer, being the lagoon of the Parque Criollo the one with the lowest values. The lagoon of the REFCV presents a eutrophic state with a tendency to hypertrophic and the lagoon of the REPC a hypertrophic state throughout the different \nseasons of the year, trophic levels like the other pampasic lagoons, which triggers a series of\nenvironmental problems (hypoxic zones, harmful algal blooms, degradation of cultural and social values). The limiting nutrient in the lagoon of the REPC is N in all seasons, while in the lagoon of the REFCV can be both N and P, depending on the season of the year. \nThis study suggests the need to elaborate a management plan that allows executing guidelines \nand control measures that consider the quality of the water and the ecosystemic functioning of these lagoons. |

Buenos Aires, Argentina Vázquez, Fernanda Volpedo, Alejandra Vigil, Gabriela 2022-12-22 El aporte de nutrientes a los sistemas acuáticos ha ido aumentando simultáneamente con el \nincremento poblacional. Las reservas naturales urbanas y periurbanas son espacios \nfundamentales para la conservación de la diversidad biológica y preservación de un ambiente saludable. El incremento de las actividades humanas, la expansión de las fronteras agrícolas y el crecimiento urbanístico, traen como consecuencia diversos problemas ambientales, como la \neutrofización en sus cuerpos de agua, generado principalmente por los aportes de Nitrógeno \n(N) y Fósforo (P), que son los nutrientes más vinculados con el deterioro de los ecosistemas \nacuáticos cuando están en exceso.\nLa Reserva Ecológica El Renacer de la Laguna (REFCV) ubicada en la Facultad de Ciencias \nVeterinarias de la UBA (FCV-UBA) y la Reserva Natural Parque Criollo de San Antonio de Areco (REPC), son áreas destinadas a la educación ambiental y al contacto de la comunidad con la naturaleza; sin embargo, no poseen planes de manejo, lo cual dificulta la gestión integral de estas áreas protegidas. El objetivo de este trabajo es evaluar los aportes de N y P, y \nel grado de eutrofización de las lagunas de estas dos reservas naturales urbanas, a fin de elaborar lineamientos para el desarrollo de un futuro plan de manejo de estos cuerpos de agua.\nLos principales resultados muestran que los valores de Nt estimado y Pt en la laguna de la \nReserva Ecológica El Renacer de la Laguna oscilan de 10,53 a 123,64 mg/L y de ?0,001 a \n0,24 mg/L estacionalmente, mientras que en la laguna de la Reserva Natural Parque Criollo \nvarían de 25,19 a 29,56 mg/L y de 0,23 a 0,59 mg/L, respectivamente. Los valores de las \nrelaciones molares N:P estimadas en las lagunas estudiadas varían significativamente de \ninvierno a verano, siendo la laguna de la Reserva Natural Parque Criollo la que posee los \nvalores más bajos. La laguna de REFCV presenta un estado eutrófico con tendencia a hipertrófico y la laguna de la REPC un estado hipertrófico a lo largo de las distintas estaciones del año, niveles tróficos similares a las demás lagunas pampásicas. Lo que \ndesencadena una serie de problemas ambientales (zonas hipóxicas,floraciones de algas nocivas, degradación de los valores culturales y sociales). El nutriente limitante en la laguna de la REPC es el N en todas las estaciones, mientras que en la laguna de la REFCV puede ser tanto el N como el P, dependiendo la estación del año. \nEste estudio sugiere la necesidad de elaborar un plan de manejo que permita ejecutar lineamientos y medidas de control que contemplen la calidad del agua y el funcionamiento \necosistémico de estas lagunas. application/pdf Nitrogeno Fosforo Reservas urbanas Provincia de Buenos Aires Nitrogen Phosphorus Urban reserves Buenos Aires province spa Universidad de Buenos Aires.
