aimed to detect the some cyanotoxin genes in local Oscillatoria species to know their able to produce toxins [PDF]

مجلة جامعة الانبار للعلوم الصرفة
The cyanobacteria, included Ocsillatoria can produce different types of toxin called cyanotoxins. which is a wide range of structurally diverse and biologically active in freshwater, marine and terrestrial ecosystems.

A simple method for algal species discrimination in East China Sea, using multiple satellite imagery

Geoscience Letters, 2022
Satellites can help monitor harmful algal blooms in coastal regions. Methods have been developed using different satellite missions. However, it is necessary to develop a simple and useful method for discriminating harmful algal species that could be ...

Hydroclimatic conditions trigger record harmful algal bloom in western Patagonia (summer 2016)

Scientific Reports, 2018
A harmful algal bloom (HAB) of the raphidophyta alga Pseudochattonella cf. verruculosa during the 2016 austral summer (February-March) killed nearly 12% of the Chilean salmon production, causing the worst mass mortality of fish and shellfish ever ...

Light and temperature as triggers for surface filamentous green algal blooms in shallow freshwater systems

Limnology and Oceanography, EarlyView.
Abstract Blooms of filamentous green algae (FGA) form dense mats at the surface of shallow freshwaters and have multiple negative impacts on aquatic ecosystem functions, services, and aesthetics. Although nutrient enrichment in freshwaters is a primary driver of excessive FGA growth, much less is known about other abiotic factors controlling bloom ...

A Review of Cyanophage–Host Relationships: Highlighting Cyanophages as a Potential Cyanobacteria Control Strategy

Toxins, 2022
Harmful algal blooms (HABs) are naturally occurring phenomena, and cyanobacteria are the most commonly occurring HABs in freshwater systems. Cyanobacteria HABs (cyanoHABs) negatively affect ecosystems and drinking water resources through the production ...

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

Limnology 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 ...

Harmful algal blooms and Vibrio spp. association in fishing and marine farming areas of mollusk bivalves in Sechura and Pisco bays, Peru

Revista Peruana de Biología, 2017
Between February 2010 and May 2014, 22 surveys in Pisco and 16 in Sechura were conducted; both are major areas for shellfish production and mariculture in Peru.

Unique thermal mixing patterns in Lake Ontario revealed by novel year‐round observations of thermal stratification

Limnology and Oceanography, EarlyView.
Abstract Year‐round records of thermal stratification in the Great Lakes are rare, and there are few observations of thermal stratification during winter. In this paper, we analyze temperature data from 13 temperature logger chains and from over 130 benthic acoustic receivers that were deployed across Lake Ontario for 2 yr.

Comprehensive study of algal blooms variation in Jiaozhou Bay based on google earth engine and deep learning

Scientific Reports, 2023
The Jiaozhou Bay ecosystem, a crucial marine ecosystem in China, has been plagued by frequent harmful algal blooms as due to deteriorating water quality and eutrophication.

Interactive effects of stoichiometry and environmental variability regulate cyanobacteria toxicity in two eutrophic bays

Limnology and Oceanography, EarlyView.
Abstract Cyanobacteria blooms are a leading threat to water quality globally. Despite this, the timing and frequency of toxin production associated with harmful blooms are not well understood. Here we explore cyanobacteria bloom dynamics and cyanotoxin production in two heavily instrumented shallow, eutrophic bays of Lake Champlain through the lens of ...
