A água é um bem limitado, razão da crescente preocupação com os recursos hidrícos e a qualidade ambiental. A poluião é um sério problema que impacta nascentes e cursos d'agua, havendo necessidade urgente de pesquisas de tratamento e de preservação. Uma das formas de tratamento de esgoto é a utilizção de filtros biológicos, com brejos construídos, ou de lagoas com plantas aquáticas. Tanques com plantas aquáticas assim como brejos agem com filtros de poluentes, ajudando a devolver a água limpa aos manaciais. Algumas plantas despoluidoras são sugeridas pela sua capacidade de retirar da água nutrientes e substâncias tóxicas, dando condições favoráveis para a base alimentar nos ecossistemas aquáticos. Lemnaceas ou lentilhas d'água são muito usadas no caso das...

Submerged macrophytes play an important role in structuring habitats and, therefore, in determining patterns of aquatic biodiversity. Because these plants are widespread in shallow areas of many Neotropical reservoirs, the present work investigated if variables related to habitat structure, measured in patches of submerged macrophytes (Egeria densa and E. najas), can be used to predict fish assemblage attributes (fish density and species richness). Based on patch characteristics at fine spatial extents (macrophyte patches within reservoir arms), we considered plant biomass, volume and proportional volume (i.e. percentage of macrophyte volume in the water column) as potential predictors. Fish and macrophytes were sampled with a 1-m² throw trap in littoral...

Canón. In this paper, we analyze the changes in composition and abundance of fish assemblages in seven vegetated floodplain wetlands with different connectivity across different hydrologic conditions: after a prolonged connection of the floodplain with the main channel, during receding water, and after a prolonged isolation. We also investigated the size and abundance of large-sized migratory species found in these wetlands and the food resources exploited by the dominant fish. Fishes were captured by diurnal seining (8.0 m x 1.50 m, 5 mm mesh) along macrophyte banks. Despite the high total number of species registered (100), sample species richness varied between 7 and 31, depending on the sampling site and the sampling date. Cluster analysis indicated low...

The effect of temperature, pH and trace elements concentration in the ambient water on the uptake and accumulation of Cu, Zn, Ni and Pb in various organs of fish and parts of aquatic plants of Edku Lake were studied. It was found that higher water temperature and lower pH during summer increased the rates of trace metals uptake by the most common fish species Oreochromis niloticus. The concentrations of Cu, Zn, and Ni in the various organs of fish were affected by the concentrations of these elements in the water. Cu, Zn, Ni and Pb attained higher concentrations in the roots of Eichormia crassipes if compared with their concentrations in the other parts of this aquatic plant. Sex of fish can be considered as an important factor affecting the accumulation...

Two projects undertaken at the Heriot-Watt University, Edinburgh, U.K as part of the WIOMSA Marg II Programme are presented here. Project 1 was on studies carried out on the Kenyan marine cyanobacterium Lyngbya majuscula, which was collected from Shimoni, 100 km south of Mombasa, Kenya and ferried to the U.K on 12th October 2003. Specifically, L. majuscula was investigated on the potential for bioprocess intensified production of secondary metabolites with therapeutic potential, the Chemistry of its secondary metabolites and that of the cultures, and on the 16S rDNA classification of its epiphytic bacteria isolates. Project 2 focused on the isolation of cell-cell signaling inducer compounds from biofilms of marine bacteria Bacillus licheniformis EI-34-6.

The distribution of Lake Victoria (Kenya) macrophytes is described. Succession of macrophytes in the lake became more dramatic and dynamic after invasion of water hyacinth. The weed pushes and smothers other free-floating macrophytes like Pistia stratiotes. It then provides substrates for the emergent Vossia cuspidata, which later reduces its population by competition for light and nutrients. The noxious weed is believed to have led to extinction of Azolla nilotica in the lake.

The paper presents data collected in an assessment of effects of water hyacinth infestation on phytoplankton productivity in Lake Naivasha, Kenya. A summary of the status of control and strategies for the future is given. The ecological effects of water hyacinth, Eichhornia Crassipes, on Lake Naivasha have received little attention compared to the large body of work available on the weed’s socioeconomic impact on the country’s water ways and methods for its removal. This study was conducted to determine if water hyacinth infestation in Lake Naivasha affects phytoplankton productivity. Several sampling stations were set up in the lake at sites where the floating mats of the weed were present and sites where the weed was absent. Phytoplankton chlorophyll-a...

La croissance des formes primaire (forme colonisatrice) et tertiaire (forme en "tapis dense") de la fougère d'eau Salvinia molesta (Salviniaceae) a été suivie pendant 60 jours dans des récipients de surface de 0.06m2 et contenant de l'eau douce. La croissance en fonction du temps de cette espèce est exponentielle. Les deux formes d'expansion présentent des taux de croissance statistiquement identiques. L'accroissement journalier moyen, exprimé en nombre de feuilles, est égal à 6,40% par jour pour la forme colonisatrice et à 5,90% par jour pour la forme en "tapis dense" avec des temps de doublement moyens équivalents à 10,78+_ 1.08 jours et à 11.64+_ 0,15 jours.

The potential of three aquatic macrophytes, Azoll caroliniana, Salvinia minima and Lemna gibba, was evaluated in this work aimed at selection of plants to be used in remediation of environments contaminated by arsenic (As). The experiments were carried out in a greenhouse during six days in pots containing Hoagland solution (¼ ionic strength) at As concentrations of 0.5; 2.5 and 5.0 mg L-1. The three species showed greater As accumulation as the concentration of the metalloid in solution increased. However, a reduction was detected in fresh and dry mass gain when the plants were exposed to high As concentrations. The macrophytes showed differences in efficiency of removal of As in solution.

ABSTRACT: The goal of the study was to evaluate the effect of 2.4-D and clomazone doses on the growth of the submerged macrophytes Egeria densa and E. najas, in microassay conditions. Therefore, tests were conducted in a bioassay room at the temperature of 27.0 ± 2.0 °C, photoperiod of 24 light hours and illumination of 500 lux. The apical fragments (shoot tips) of the macrophytes with 5.0 cm of length were transferred to test tubes with a 100 mL capacity, containing 70 mL of water. The tested concentrations were: 0.1; 1.0; 3.5; 11.2; 36.5; and 118.0 mg L-1 and a control sample with seven replications.
