Los humedales de Lima son parte de un corredor biológico a lo largo de la costa desértica del Perú. A pesar de los múltiples estudios florísticos realizados en estos ambientes, poco se conoce acerca de estructura comunitaria. Con el objetivo de conocer la estructura de las comunidades vegetales se realizó un análisis cuantitativo por transectos y su posterior evaluación con métodos multivariados. Cuatro humedales fueron estudiados (Puerto Viejo, Cañete; Santa Rosa, Huaral; Paraíso, Chancay y Medio Mundo, Végeta). Se encontró que cada humedal presenta una estructura particular y compleja de sus comunidades vegetales, la cual guarda íntima relación con las actividades antrópicas de cada localidad. Se identificó a la ganadería y agricultura como una de sus principales amenazas. Se propone que la estructuración de las comunidades vegetales es un potencial bioindic...

The increasing use of pesticides generates negative effects on biodiversity by exposing freshwater snails, which stand out as the most affected group of gastropods globally. Therefore, the objective of this research is to analyze the ecotoxicological effects of pesticide exposure on freshwater snails, evaluating the impacts on various organs. For this purpose, a search was carried out in databases such as Scopus, Sciencedirect, Web of science and Scielo, in a specific interval of years, 1999-2024. In this context, the articles analyzed focused on the evaluation of different species, especially Lymnaea stagnalis (Linnaeus, 1758), Physella acuta (Draparnaud, 1805), Chilina parchappii (d'Orbigny, 1835) and Planorbarius corneus (Linnaeus, 1758) due to their sensitivity to various pollutants and adaptation to different laboratory conditions, which facilitates their use in controlled research....

Coastal wetlands adjacent to urban areas, such as the Pantanos de Villa in the city of Lima, Peru, are subject to constant changes in land use due to anthropogenic interaction. This has led to the reduction of dense vegetation areas, giving way to built-up areas. Therefore, this article addresses the issue of the physical changes experienced in urban areas adjacent to the wetland, such as the environmental management units, in this case the Zone of Protection of Outcrop and Surface Runoff (ZPAES), and the Zone of Landscape Protection of Edge (ZPB), as well as the Pantanos de Villa Wildlife Refuge (RVSPV), as a result of rapid urban expansion. Therefore, the objective of this research is to analyze the spatial and temporal evolution of the Pantanos de Villa environment and urbanization within the Environmental Management Units ZPB, ZPAES, and RVSPV. To achieve this, the Google Earth Engin...
