“…The first three species mentioned grew mainly in waters with flow velocity higher than 40 cm s −1 , where they were found on substrate with the mean size of over 5 cm. The occurrence and preference of Fontinalis antipyretica (Fon ant), Myriophyllum spicatum (Myr spi), and Rhynchostegium riparioides (Rhy rip) to the faster flowing waters and hard substrates are know from Northern Spain (Myr spi; Onaindia et al, 1996) or Great Britain (Fon ant; Dawson & Szoszkiewicz, 1999) and Orne river in France (Fon ant and Myr spi; Bernez et al, 2004) or the Ipeľ river in Slovakia (Fon ant, Rhy rip; Hrivnák et al, 2003). Myriophyllum spicatum has a wide ecological amplitude as well.…”

Diversity of aquatic macrophytes in relation to environmental factors in the Slatina river (Slovakia)

2006

Distribution and plant mass of aquatic macrophytes, and their relation to environmental conditions was studied in the submontane-colline Slatina river in 2004. Diversity of macrophytes was low, only 8 vascular plants, 3 mosses and group Algae filamentosae were found. Myriophyllum spicatum is dominant species, Fontinalis antipyretica, Rhynchostegium riparioides and Algae filamentosae are frequent. Interactions between flow class, bed material, depth of water and the first three mentioned macrophytes, as well as Jungermannia leiantha were detected. Sparganium erectum prefers more antrophogenic conditions and Myriophyllum spicatum prefers the light. According to cluster analysis, three distinct and ecologically well separated parts of the river were identified. Based on Reference index, poor ecological status for the studied part of the Slatina river was estimated.

“…Berger-Parker index was chosen and FBI had been widely used to reflect water quality contaminated to varied extents [37]. Aquatic plants were able to absorb harmful substances and pollutants, functioned as an indicator of the eutrophic status of a water body [38] and provided a habitat and shelter for a variety of shellfish and small invertebrates [39,40]. Areal coverage was selected as a parameter to describe the status of wetland plants.…”

Abstract:The development of an ecosystem health index to assess health status in freshwater lakes is urgently needed in China, especially in polluted lakes. This study developed a specific Ecosystem Health Index (LP-EHI) for Lake Poyang in China. LP-EHI quantified lake health from the perspectives of physical, chemical, biological integrity and social service. Physical integrity indices included hydrological conditions (water level and runoff), basic morphometric characteristics (lake area and shoreline), and tributary connectivity. Chemical integrity indices used water quality, nutrition, and toxicity to quantify chemical impairment. Biological integrity indicators covered six major components of the aquatic food chain, namely, phytoplankton, zooplankton, benthic macroinvertebrates, wetland plants, fish, and wintering birds. Social service indices included drinking water, pathogenic potential, flood storage capacity, sand mining, and dish-shaped sub-lake areas under management to measure whether the lake fulfilled the needs of human society. Reference and impaired conditions for each metric were defined by "historical" conditions, "least disturbed" conditions, national standards and expert opinions. The value of LP-EHI ranging from 0 to 1 was divided into five health conditions: excellent (≥0.8), good (0.6-0.8), fair (0.4-0.6), poor (0.2-0.4) and bad (<0.2). The metrics' reliability was further validated using a box-and-whisker plot test. The developed index (LP-EHI) is so far the most comprehensive index to evaluate ecosystem health for Lake Poyang, and is well reflected in the unique characteristics of Lake Poyang. It can enhance our understanding of lake health conditions and thus guide lake management to achieve better health conditions.

“…Onaindia et al (1996) avaliaram a relação entre a ocorrência de plantas aquáticas e fatores ambientais em alguns rios da Espanha. Os pesquisadores encontraram altos valores de condutividade elétrica, com amplitude de 200 a 9.560 µS cm -1 , e os associaram, em alguns casos, à formação de gesso e, em outros, à poluição urbana e industrial.…”

“…Contudo, ainda em relação à concentração de amônio, Onaindia et al (1996) relataram que a principal via de entrada desse íon no ecossistema aquático é consequência da poluição gerada por despejos urbanos e agrícolas; altas concentrações de NH 4 + foram correlacionadas com a ausência de plantas aquáticas, o que pode ser considerado um efeito da toxicidade desse íon. A distribuição de plantas aquáticas analisada neste estudo citado foi limitada por zonas altamente mineralizadas e eutrofizadas, as quais foram ocasionadas pela poluição industrial.…”

Este estudo teve como objetivos monitorar a distribuição de populações de Brachiaria subquadripara e caracterizar seu ambiente de ocorrência em duas épocas (seca e águas). As coletas foram realizadas em julho de 2004 e janeiro de 2005 em pontos previamente selecionados e georreferenciados, os quais se constituíram de 13 pontos no reservatório Barra Bonita (sete pontos no braço do rio Piracicaba e seis no braço do rio Tietê). Foram realizadas coletas de solo nas margens dos rios, sedimento, água e plantas. A distribuição em relação à área de infestação das populações de B. subquadripara observada na estação chuvosa foi influenciada pela variação sazonal, a qual ocorreu de forma heterogênea em relação à densidade populacional. O rio Tietê foi considerado um ambiente mais eutrófico do que o rio Piracicaba tanto em relação ao solo quanto em relação à coluna d'água. As amostras de água coletadas no rio Tietê apresentaram valores médios de pH na estação seca de 7,02 a 7,82, e na estação das águas registrou-se maior amplitude de variação (6,80 a 8,0). A maioria dos pontos amostrados apresentou altos teores de matéria orgânica no sedimento, sendo observados teores menores que 1,3% em dois pontos de coleta na época da seca e em cinco pontos na época das águas.
