Integrating phytoplankton phenology, traits, and model‐data fusion to advance bloom prediction

Limnology and Oceanography Letters, EarlyView.
Abstract While there is a diversity of approaches for modeling phytoplankton blooms, their accuracy in predicting the onset and manifestation of a bloom is still lagging behind what is needed to support effective management. We outline a framework that integrates trait theory and ecosystem modeling to improve bloom prediction.

Cyanotoxins: New health risk factor in Serbia [PDF]

Archive of Oncology, 2008
Cyanobacteria are responsible for poisoning numerous cases of livestock and other animals, but sometimes they induce serious problems in humans. Mass occurrence and blooms of cyanobacteria were studied in rivers, canals, lakes, and accu­mulations that ...

Chitosan-cellulose Composite Materials: Preparation, Characterization and Application for Removal of Microcystin [PDF]

, 2013
We developed a simple and one-step method to prepare biocompatible composites from cellulose (CEL) and chitosan (CS). [BMIm+Cl−], an ionic liquid (IL), was used as a green solvent to dissolve and prepare the [CEL + CS] composites. Since majority (\u3e88%)

A novel artificial intelligence–powered cell counting tool coupled with digital microscopy for rapid field‐assessment of harmful cyanobacterial blooms

Limnology and Oceanography: Methods, EarlyView.
ABSTRACT Historical quantification of cyanobacterial harmful algal blooms (cHABs) typically involved labor‐intensive manual cell counting. We developed a novel, cost‐effective, field‐validated system to perform cell counts of six common toxin‐producing cyanobacterial genera within 30 s of upload with 10‐min sample preparation.

Coagulation/flocculation/flotation/nanofiltration processes using Moringa Oleifera as coagulant of Eutrophized river [PDF]

, 2015
This study investigated the efficiency of Moringa oleifera (MO) seeds as natural coagulant in coagulation/flocculation/dissolved air flotation (C/F/DAF), followed by nanofiltration (NF) for Microcystis protocystis and microcystin-LR removal.

Cyanotoxins: A Poison that Frees Phosphate [PDF]

Current Biology, 2010
Autotrophic organisms obtain phosphorus from the environment by secreting alkaline phosphatases that act on esters, resulting in inorganic phosphate that is then taken up. New work shows that the cyanobacterium Aphanizomenon ovalisporum obtains inorganic phosphate by secreting the cyanotoxin cylindrospermopsin, which induces alkaline phosphatase in ...

Reimagining Urban River Bathing in Europe: A Multisectoral and Interdisciplinary Dive Into Lyon's Rivers (France)

River Research and Applications, EarlyView.
ABSTRACT Urban river bathing is re‐emerging across Europe, driven by social demand and climate change impacts. The Urban Bathing Consortium, an interdisciplinary and intersectoral consortium initiated at the University of Lyon (France), is at the forefront of studying the challenges and opportunities of creating and managing healthy, safe, and ...
