Metagenomic analysis of a freshwater toxic cyanobacteria bloom. [PDF]
FEMS microbiology ecology, 2008 High molecular weight (HMW) DNA prepared from a toxic freshwater cyanobacterial bloom sample was used to construct a PCR-generated 75-clone, 16S rRNA gene library and a 2850-clone bacterial artificial chromosome (BAC) library. Phylogenetic analysis of the 16S rRNA gene library demonstrated that members of eight phyla of domain Bacteria, which included ...

Environmental Toxicology, EarlyView.ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Identify and Report Water Pollution: An Interpretive Guide to Surface Water Conditions of the New Hampshire Coastal Watershed, 2nd edition [PDF]
, 2007 This gude was designed to help people who work or recreate outdoors to interpret surface water conditions so that they would recognize a pollution incident and know how to report it.

Physical measures to inhibit planktonic cyanobacteriae [PDF]
, 1992 In a small lake, intermittent destratification was installed after several other physico-chemical and physical in-lake therapy measures (phosphorus immobilization, permanent destratification) had been tested without great success.

Characteristics of Wetting-Induced Bacteriophage Blooms in Biological Soil Crust. [PDF]
, 2019 Biological soil crusts (biocrusts) are photosynthetic "hot spots" in deserts and cover ∼12% of the Earth's terrestrial surface, and yet they face an uncertain future given expected shifts in rainfall events.

Nitrogen availability facilitates phosphorus acquisition by bloom-forming cyanobacteria [PDF]
FEMS Microbiology Ecology, 2018 Cyanobacterial blooms are threatening freshwater ecosystems. The physiological basis involved in the onset of cyanobacterial bloom is fundamental to advance in bloom predictions. Generally, cyanobacteria grow until the availability of nitrogen (N), phosphorus (P) or both nutrients becomes limited.

Journal of Animal Ecology, EarlyView.Partial seasonal migration is rarely considered in a metapopulation context. Here, Haaland et al. use an eco‐evolutionary model revealing how partially migratory metapopulations may arise and be maintained, and how seasonal migrants may cause effects of local extreme climatic events to percolate through metapopulations across diverging temporal and ...

Evaluating Ultrasonicator Performance for Cyanobacteria Management at Freshwater Sources
Toxins, 2023 Algal blooms consisting of potentially toxic cyanobacteria are a growing source water management challenge faced by water utilities globally. Commercially available sonication devices are designed to mitigate this challenge by targeting cyanobacteria ...

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho
Fisheries Management and Ecology, EarlyView.ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

ToxinsHarmful algal bloom (HAB) formation leads to the eutrophication of water ecosystems and may render recreational lakes unsuitable for human use. We evaluated the applicability and comparison of metabarcoding, metagenomics, qPCR, and ELISA-based methods ...
