Blue-Green Algae and the Seasonal Succession of Daphnia

, 2001
The cladoceran Daphnia lumholtzi invaded North America from the Old World tropics and has since spread across much of the southern United States. This exotic cladoceran is most common during midsummer, when native Daphnia are rare and Cyanobacteria (blue-

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

Limnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Removal of cadmium from polluted water by immobilized algae [PDF]

, 1990
A feasibility study was planned to determine the efficiency of immobilized algal cells growing in a packed bed for removing Cd from commercial effluents. To select appropriate material for an immobilized cell system, twenty-five strains of algae isolated

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

Nordic Journal of Botany, EarlyView.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

On the botanical history and nomenclature of the New World genus Piscidia (Fabaceae)

Nordic Journal of Botany, EarlyView.
Piscidia L. (Fabaceae) is a New World genus with nine recognized taxa (seven species and two varieties). The previous nomenclatural revisions, made in 1910 and in 1969, are revisited here. The names Derris grandifolia Heyde & Lux ex Donn.Sm. and P. cubensis Urb. required step II lectotypifications, with an epitype for the latter name.

Isolation, Identification and Characterization of Blue-green Algae-lysing Strain DC-L14 from Lake Dianchi, China

, 2009
An algae-lysing strain DC-L14 was isolated from an area with dense blue-green algae in Lake Dianchi, southwestern China and it was identified as Lysinibacillus fusiformis based on 16S rDNA sequence analysis.

What turns us off about green and blue spaces in cities? Understanding perceived problems and unpleasant experiences for more just urban planning, design and management

People and Nature, EarlyView.
Abstract The planning, design and management of urban green and blue spaces necessitate trade‐offs between these spaces' many benefits and their drawbacks, but knowledge of perceived problems and unpleasant experiences in urban green and blue spaces remains limited.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...
