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 ...

Algal Bloom Prediction Using Extreme Learning Machine Models at Artificial Weirs in the Nakdong River, Korea

International Journal of Environmental Research and Public Health, 2018
In this study, we design an intelligent model to predict chlorophyll-a concentration, which is the primary indicator of algal blooms, using extreme learning machine (ELM) models.

Cyanophage Engineering for Algal Blooms Control

Viruses
Cyanobacteria represent a prevalent category of photosynthetic autotrophs capable of generating deleterious algal blooms, commonly known as cyanobacteria harmful algal blooms (cyanoHABs). These blooms often produce cyanotoxins, which pose risks to public health and ecosystems by contaminating surface waters and drinking water sources.

Income and capital breeding

Limnology and Oceanography, EarlyView.
Abstract Copepods of the genus Calanus are key species in the energy transfer from primary producers to higher trophic levels in Arctic and sub‐Arctic seas. The timing of reproduction can differ between species, depending on whether they rely on external energy sources to initiate reproduction (income breeders) or use internal energy sources (capital ...

HARMFUL ALGAL BLOOMS IN THE MEDITERRANEAN SEA: EFFECTS ON HUMAN HEALTH.

Euromediterranean Biomedical Journal, 2013
A harmful algal bloom (HAB) is defined as a bloom that has deleterious effects on plants, animals or humans. Marine algal toxins are responsible for an array of human illnesses associated with consumption of seafood or exposure to aerosolized toxins ...

Prediction of short-term algal bloom using the M5P model-tree and extreme learning machine

Environmental Engineering Research, 2018
In this study, we designed a data-driven model to predict chlorophyll-a using M5P model tree and extreme learning machine (ELM). The Juksan weir in the Youngsan River has high chlorophyll-a, which is the primary indicator of algal bloom every year. Short-

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.

Planning for the future, algae bloom dynamics in water management and ecosystem restoration efforts

Frontiers in Water
Eutrophication and chronic harmful algal blooms (HABs) are a challenge for ecosystem managers and restoration planners. Drivers of HABs include nutrient availability, temperature patterns, atmospheric conditions, rainfall-runoff relationships, and lake ...

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 ...

Harmful algal blooms are preceded by a predictable and quantifiable shift in the oceanic microbiome

Nature Communications
Harmful algal blooms (HABs) have become a worldwide environmental and human health problem, stressing the urgent need for a reliable forecasting tool. Dynamic interactions between algae, including harmful algae, and bacteria play a large role regulating ...
