Cyanobufalins: Cardioactive Toxins from Cyanobacterial Blooms [PDF]

open access: yesJournal of Natural Products, 2018
Cyanobufalins A-C (1-3), a new series of cardiotoxic steroids, have been discovered from cyanobacterial blooms in Buckeye Lake and Grand Lake St. Marys in Ohio. Compounds 1-3 contain distinctive structural features, including geminal methyl groups at C-4, a 7,8 double bond, and a C-16 chlorine substituent that distinguish them from plant- or animal ...

Warming enhances primary production and respiration and changes plankton community structure in an estuarine upwelling system

open access: yesLimnology and Oceanography, EarlyView.
Abstract Marine heatwaves are expected to become more frequent and intense due to global climate change, potentially impacting plankton communities. In the present study, the effects of a simulated short‐term warming event on the structure and functioning of coastal plankton communities were investigated during a mesocosm experiment conducted with ...

Microcystins in components of twelve New Hampshire lakes of varied trophic status [PDF]

open access: yes, 1999
Cyanobacteria toxins, called microcystins (MCs), were found in components of twelve, stratified New Hampshire (USA) lakes of varied trophic status during the summer of 1998.

Blooms of cyanobacteria in a temperate Australian lagoon system post and prior to European settlement [PDF]

open access: yes, 2016
Blooms of noxious N2 fixing cyanobacteria such as Nodularia spumigena are a recurring problem in some estuaries; however, the historic occurrence of such blooms in unclear in many cases.

Incorporation of diazotrophically fixed nitrogen by juvenile fish in a coastal sea

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrogen‐fixing cyanobacterial blooms worldwide have been shown to support production in primary consumers such as zooplankton and benthic invertebrates, but there have been few estimates of how much of the cyanobacterial nitrogen ends up in secondary consumers, such as fish.

Simulation and control of the cyanobacterial bloom biomass in a typical plateau lake based on the logistic growth model: A case study of Xingyun Lake

open access: yesEcological Informatics
The simulation and early warning of cyanobacterial blooms in lakes are of great significance. Controlling the growth of cyanobacteria in plateau lakes is challenging due to the unique geographical environment, climatic conditions, and impact of ...

A global meta‐analysis of ecological functions and regulating ecosystem services of freshwater bivalves

open access: yesLimnology and Oceanography, EarlyView.
Abstract Freshwater bivalves are globally distributed, diverse, and common in benthic communities. Many taxa, particularly in the most species‐rich order, Unionida, are declining due to anthropogenic stressors, while a small number of non‐native species have become increasingly abundant and widespread, commonly replacing native bivalve assemblages.

Nitrogen forms influence microcystin concentration and composition via changes in cyanobacterial community structure. [PDF]

open access: yesPLoS ONE, 2014
The eutrophication of freshwaters is a global health concern as lakes with excess nutrients are often subject to toxic cyanobacterial blooms. Although phosphorus is considered the main element regulating cyanobacterial biomass, nitrogen (N) concentration

Contact‐dependent iron uptake from dust revealed by elemental analysis of single Trichodesmium colonies

open access: yesLimnology and Oceanography, EarlyView.
Abstract Aerosol dust deposited on the nutrient‐deprived surface ocean can boost phytoplankton growth and oceanic carbon uptake. Low mineral solubility restricts the biological utilization of dust‐nutrients, thereby benefiting phytoplankton that actively dissolve dust.
