Temporal and spatial variation of limnological variables and biomass of different macrophyte species in a Neotropical reservoir (São Paulo - Brazil) [PDF]

open access: yes, 2013
Aim: This study reports an investigation of limnological characteristics and aquatic macrophyte occurrence in a neotropical reservoir in order to assess the spatio-temporal variation of water and sediment variables and their influence on plant ...

Factors affecting the distribution patterns of aquatic macrophytes

open access: yesLimnological Review, 2014
Aquatic macrophytes constitute important components of many freshwater ecosystems. The manifold role of aquatic macrophytes in freshwater habitats is closely linked to their distribution, which in turn depends on a myriad of factors.

Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]

open access: yes, 2014
Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems.

Arsenic accumulation by edible aquatic macrophytes

open access: yesEcotoxicology and Environmental Safety, 2014
Edible aquatic macrophytes grown in arsenic (As)-contaminated soil and sediment were investigated to determine the extent of As accumulation and potential risk to humans when consumed. Nasturtium officinale (watercress) and Diplazium esculentum (warabi) are two aquatic macrophytes grown and consumed in Hawaii. Neither has been assessed for potential to

Influence of limnological variables on aquatic macrophytes in the Belo Monte reservoir, Amazon, Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências
The demand for electricity grows with human expansion. Hydroelectric plants harness river energy but impact freshwater ecosystems. Reservoirs alter water flow, sediment, and local aquatic communities.

Efficient sampling methodologies for lake littoral invertebrates in compliance with the European Water Framework Directive [PDF]

open access: yes, 2015
Lake shores are characterised by a high natural variability, which is increasingly threatened by a multitude of anthropogenic disturbances including morphological alterations to the littoral zone. The European Water Framework Directive (EU WFD) calls for

Seasonal and spatial variation of aquatic macrophytes and phytoplankton community at El-Quanater El-Khayria River Nile, Egypt

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2018
In this study, the phytoplankton biomass and species composition in El-Quanater El-Khayria (River Nile, Egypt) was analyzed at four sampling sites on a program of a seasonally sampling and supported by measurements of different water variables as well as
