Anatomy of the root of eight species of emergent aquatic macrophytes from the upper Paraná river, Paraná State, Brazil floodplain - doi: 10.4025/actascibiolsci.v32i3.5509

Acta Scientiarum: Biological Sciences, 2010
The upper Paraná River floodplain is characterized by the existence of several aquatic and transitional habitats between the aquatic and terrestrial environment, influencing the presence and distribution of aquatic macrophytes.

Nitrogen phytoremediation by water hyacinth (Eichhornia crassipes (Mart.) Solms) [PDF]

, 2008
The phytoremediation potential of water hyacinth, Eichhornia crassipes (Mart.) Solms, was examined in two independent studies under nitrogen (N) rates of 0, 40, 80, 100, 150, 200, and 300 ppm.

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider

Ecological Entomology, EarlyView.
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Local ciliate communities associated with aquatic macrophytes.

International microbiology : the official journal of the Spanish Society for Microbiology, 2014
This study, based within the catchment area of the River Frome, an important chalk stream in the south of England, compared ciliated protozoan communities associated with three species of aquatic macrophyte common to lotic habitats: Ranunculus penicillatus subsp. pseudofluitans, Nasturtium officinale and Sparganium emersum.

Resilience of riparian spiders to floods: evidence from a mesocosm study

Insect Conservation and Diversity, EarlyView.
Mesocosm experiment to assess the impact of flood duration on flood‐naïve riparian spider communities. In May, spider richness decreased with flood duration, while in June, flood duration increased abundance, richness and promoted wetland specialists. Flood‐naïve riparian spiders unexpectedly appear highly resilient to flooding.

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...
