Seasonal genotypic and phenotypic differentiation of a cosmopolitan freshwater diatom

Limnology and Oceanography, EarlyView.
Abstract Most ecosystems are characterized by seasonality, which, through biotic and abiotic changes, influences species biomass dynamics. Recent studies have shown that ecologically important traits can evolve rapidly in response to environmental changes, resulting in eco‐evolutionary dynamics with consequences for population and community dynamics ...

Harmful blooms across a longitudinal gradient in central Europe during heatwave: Cyanobacteria biomass, cyanotoxins, and nutrients

Ecological Indicators
Climate change has increased the frequency, duration and intensity of heatwaves in Europe. These extreme events result in alterations of physical, chemical, and biological properties of lakes that may synergistically promote cyanobacterial dominance.

The fungicide azoxystrobin promotes freshwater cyanobacterial dominance through altering competition

Microbiome, 2019
Background Sharp increases in food production worldwide are attributable to agricultural intensification aided by heavy use of agrochemicals. This massive use of pesticides and fertilizers in combination with global climate change has led to collateral ...

MALDI-TOF mass spectrometry of Cyanobacteria: a global approach to the discovery of novel secondary metabolites [PDF]

, 2008
Cyanobacteria (blue-green algae) are a group of ancient prokaryotic organisms dating back between three and four billion years.¹ They have been attributed with oxygenating the earth’s atmosphere² but, since the anthropogenic euthrophication of lakes ...

Bacteria homologus to Aeromonas capable of microcystin degradation [PDF]

, 2014
Water blooms dominated by cyanobacteria are capable of producing hepatotoxins known as microcystins. These toxins are dangerous to people and to the environment. Therefore, for a better understanding of the biological termination of this increasingly

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.

Community Structure and Toxicity Potential of Cyanobacteria during Summer and Winter in a Temperate-Zone Lake Susceptible to Phytoplankton Blooms

Toxins
Cyanobacterial blooms are increasingly common during winters, especially when they are mild. The goal of this study was to determine the summer and winter phytoplankton community structure, cyanotoxin presence, and toxigenicity in a eutrophic lake ...

Cyanobacteria as biological drivers of lake nitrogen and phosphorus cycling

Ecosphere, 2015
Here we draw attention to the potential for pelagic bloom‐forming cyanobacteria to have substantial effects on nutrient cycling and ecosystem resilience across a wide range of lakes.

Salinity is diagnostic of maximum potential chlorophyll and phytoplankton community structure in an Eastern Boundary Upwelling System

Limnology and Oceanography Letters, EarlyView.
Abstract Coastal upwelling ecosystems associated with strong physical stirring exhibit significant mesoscale hydrographic and biological patchiness. Though many studies have found broad correlations between hydrographic properties (e.g., temperature and salinity) and phytoplankton biomass, we lack a detailed understanding of the mechanisms underlying ...

Eutrophication and cyanobacteria in South Africa’s standing water bodies: A view from space

South African Journal of Science, 2015
Satellite remote sensing can make a significant contribution to monitoring water quality in South African standing water bodies. Eutrophication, defined as enrichment by nutrients, and toxin-producing cyanobacteria (blue-green algae) blooms pose a ...
