Constructed wetland in wastewater treatment = Uso de “wetland” construído para tratamento de resíduos

Acta Scientiarum: Biological Sciences, 2008
Physical and chemical variables of soil and water were measured todetermine the effectiveness of a constructed wetland for wastewater treatment. Eight different macrophyte species, namely Eichhornia crassipes, Alternanthera philoxerodos, Heteranthera ...

Water quality evaluation in Mediterranean Lagoons using the Multimetric Phytoplankton Index (MPI): study cases from Sardinia [PDF]

, 2013
1 - Water quality in four Sardinian lagoons (western Mediterranean Sea) was assessed using the Multimetric Phytoplankton Index (MPI), which is consistent with the EU Water Framework Directive.

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

Eutrophication promoted the change of macrophyte community from R strategy to C strategy in Lake Taihu

Ecological Indicators
Functional traits effectively reflect plants’ ecological strategies in response to environmental changes. This study investigated how lake eutrophication influences macrophyte communities ecological strategies by analyzing leaf functional traits along ...

The relationship between aquatic macrophytes and water quality in Nta-Wogba Stream, Port Harcourt, Nigeria [PDF]

, 2011
An empirical survey of macrophytes distribution and biomass from four stations, along Nta-wogba stream in Port Harcourt, Nigeria, was conducted between April and December 2007, to quantify the relationship between biomass, in stream nutrients and ...

Capturing Spatial Gradients of Water Color and Clarity in Subtropical Reservoirs During Drought

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Reservoirs have spatial variation in water depth, suspended matter, and biogeochemistry that can influence patterns of water clarity and color. Spatial surveys with sensor‐equipped boats matched in time with satellite image acquisition provide data‐intensive avenues for understanding spatial patterns of optical properties within reservoirs. We

Elements of the Structure of Macrophyte Metacommunities in Coastal Wetlands: Relationships With Limnological and Climatic Variables

Ecological Research, Volume 41, Issue 2, March 2026.
We applied the Elements of Metacommunity Structure (EMS) framework to macrophyte communities across coastal wetlands in southern Brazil, identifying distinct distribution patterns among functional groups. Our results show that environmental and climatic factors shape these patterns differently, with emergent species forming Clementsian communities and ...

A global estimator of C and N isotope baselines for fresh waters

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 992-1006, March 2026.
Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Aquatic Biodiversity of the Pampa Biome: Insights From a Scientometric and Systematic Perspective

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The Pampa biome, in South America, covers parts of Brazil, Uruguay, and Argentina. Its main characteristic is the predominance of grassland areas. The Pampa biome supports high biological diversity and a wide variety of ecosystems. In this study, we provide a comprehensive overview of biodiversity studies focusing on freshwater ecosystems of ...
