Los objetivos del estudio fueron investigar la composición y estructura de la vegetación acuática dentro del sistema, con miras a identificar objetos de conservación para monitoreos posteriores, y determinar las preferencias de hábitat de las especies usando análisis de estadística no paramétrica. Se establecieron 28 transectos a lo largo del sistema, los mismos que fueron ubicados sobre los diferentes tipos de vegetación. Se analizaron las similitudes en la distribución de las especies con el índice de Jaccard, mientras que las similitudes en los patrones de cobertura se analizaron con el índice de Steinhaus. La variación de los parámetros ambientales en los puntos de muestreo fue confrontada con un análisis de componentes principales (PCA). Se identificaron tres tipos de vegetación: gramalote, dominante en ambientes lóticos (río y meandros); mandial, presente únicamente en las lagunas de Delfincocha e Imuya; y la vegetación de rivera, común en la mayoría de ambientes lénticos (lagunas). Se identificaron 28 especies de plantas acuáticas entre tolerantes (helófitas) y estrictas (hidrófitas), de las cuales únicamente cinco tienen amplia distribución dentro del sistema y tres se encuentran restringidas a un solo tipo de ambiente. Se registraron cuatro formas de vida: las plantas enraizadas flotantes, que dominan (43% de las especies), las enraizadas emergentes (32%), las flotantes libres (14%) y las enraizadas sumergidas (11%). Por la riqueza de especies y los diferentes tipos de vegetación presentes en las lagunas de Imuya y Delfincocha es necesario considerar estos ambientes como objetos de conservación, tomando en cuenta que existen además pequeñas poblaciones de Cabomba furcata Schult. & Schult. f, (Cabombaceae), Hydrocotyle ranunculoides L. f. (Apiaceae) y Najas arguta Kunth (Najadaceae) creciendo en estas dos lagunas y consecuentemente podrían ser los únicos registros dentro del sistema.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[An assessment of floristic assemblage of aquatic vascular plants was carried out in the Lagartococha riberine system of the Reserva de Producción Faunística Cuyabeno (RPFC) in the Amazon basin of Ecuador. The aims of the study were to determine the structure and composition of aquatic vegetation within riparian environments, aimed to recognize conservation targets for monitoring programs and identify the species habitat preferences applying non parametric statistic analysis. Twenty eight transects were established across the riverine system, located over different types of vegetation. The similarities in aquatic plants distribution were analysed with Jaccard Index, while the similarities of cover patterns were analysed by Steinhaus Index. The changing patterns of environment conditions in the sampling places were correlated by a Principal Component Analysis. Three kinds of vegetation were determined: gramalote, dominant in lotic environments; mandial, growing only in Delfincocha and Imuya lakes and riparian vegetation spread along the most lentic environments (lakes). Twenty eight aquatic vascular plants were recorded including amphibians and submersed life forms. Only five species have widespread distribution across the river system and three species were restricted to one kind of environment. Four life forms were recorded: the rooted floating plants, which are dominants (43% of the overall species), the emergent rooted plants (32%), the free floating plants (14%) and the submersed rooted plants (11%). According with the species richness and the different kinds of vegetation which are growing in Delfincocha and Imuya lakes is necessary to consider those environments as a priority target of conservation in the area. Moreover in those environments there are a few populations of Cabomba furcata Schult. & Schult. f. (Cabombaceae), Hydrocotyle ranunculoides L. f. (Apiaceae) y Najas arguta Kunth (Najadacae) that are likely unique records for this riparian system.]]></p></abstract>
