25. NUTRIENT REMOVAL FROM SWINE WASTEWATER IN A COMBINED VERTICAL AND HORIZONTAL FLOW CONSTRUCTED WETLAND SYSTEM
ABSTRACT This study aimed to assess the performance of a combined vertical flow (VFCW) and horizontal subsurface-flow (HFCW) constructed wetland systems built on a pilot scale and submitted to different configurations and organic load application rates of pre-treated swine wastewater (SWW) in anaerobic systems on the nitrogen and phosphorus removal. The aver

26. Plant species diversity in a Neotropical wetland: patterns of similarity, effects of distance, and altitude
ABSTRACT The Brazilian Pantanal is an extensive wetland with heterogeneous habitats, primarily due to the river-floodplain system and plants with differential adaptations and reproductive strategies. Factors such as altitude, distance among plant formations, and flood pulse must be considered to better understand its diversity. Aiming to assess the influence

27. Mercury content in the fur of jaguars (Panthera onca) from two areas under different levels of gold mining impact in the Brazilian Pantanal
ABSTRACT The Pantanal is the largest inland wetland in the world and is under increasing anthropogenic threats, including long-term regionally intensive gold mining practices. Gold mining activities are known to cause the release of harmful pollutants such as mercury (Hg) to the surrounding environment. Jaguars (Panthera onca (Linnaeus, 1758)) are apex preda

28. Obstrução e uniformidade em sistemas de irrigação por gotejamento aplicando-se água residuária tratada
RESUMO A utilização de águas residuárias na agricultura é uma alternativa para controle da poluição das águas superficiais, contribuindo para a promoção do uso racional da água. Assim, objetivou-se com o presente estudo avaliar a obstrução e uniformidade de de sistemas de irrigação por gotejamento aplicando-se água residuária tratada. A pesq

29. TREATMENT OF SEPTIC TANK SLUDGE IN A VERTICAL FLOW CONSTRUCTED WETLAND SYSTEM
ABSTRACT: The study consisted of the evaluation of the treatment of septic tank sludge in a vertical constructed wetland system (CW), built according to the first stage of the French system. The system operated also for sewage treatment and one of the beds (area of 29.1 m2, height of the support medium of 0.7 m and planted with Tifton 85 grass, Cynodon dacty

30. Fish population responses to hydrological variation in a seasonal wetland in southeast México
ABSTRACT Hydrological variation differently affects fish species. In the present study, the response of local populations of 13 fish local species to hydrological variation in a tropical wetland was evaluated. The objectives were to analyze the abundance response of fish species with distinct life history strategies and to assess the role of hydrological var

31. CHARACTERIZATION OF CLOGGING MATERIAL FROM HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLAND SYSTEMS
ABSTRACT This study aimed to characterize the material composition responsible for clogging the porous medium of horizontal subsurface flow constructed wetland (HSSF–CW) systems, which is detrimental to a proper system operation. Six completely clogged HSSF–CWs were used after treatment of swine wastewater. Operating conditions of these systems were name

32. Reporte y distribución potencial de una palma exótica ornamental (Roystonea oleracea) en Ecuador
Abstract The Roystonea oleracea palm, a native of the Caribbean, has been introduced in some tropical countries as an ornamental plant and it invades the wetlands of Brazil, Guyana and Panama. In this study we report the presence of R. oleracea in the coastal region of Ecuador where it is widely cultivated as an ornamental. Using a satellite image, we estima

35. HYDRAULIC CONDUCTIVITY VARIABILITY IN HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLANDS
ABSTRACT Many modifications in hydrodynamic conditions occur inside the bed of a horizontal subsurface flow constructed wetland (HSSF–CW) in operation. Studies on hydraulic conductivity measurement techniques in HSSF–CW are imperative since the monitoring of flow conditions is essential for understanding and controlling its clogging. This study aimed to

36. The partitioning of food resources between two rodents in the subtropical region of southern Brazil
ABSTRACT The capybara (Hydrochoerus hydrochaeris) and nutria (Myocastor coypus) are herbivorous semi-aquatic rodents. Although these rodents occur in sympatry in southern South America, little is known about how the two species interact in relationship to food resources. In this context, the aim of this study was to analyze the food resource overlap, the fee
