A Simple yet Accurate Method for the Estimation of the Biovolume of Planktonic Microorganisms

PLOS ONE, 2016
Determining the biomass of microbial plankton is central to the study of fluxes of energy and materials in aquatic ecosystems. This is typically accomplished by applying proper volume-to-carbon conversion factors to group-specific abundances and biovolumes.

How does human development affect the relationship between nutrients and turbidity and the cyanobacteria biovolume?

, 2020
Human activities cause drastic changes in the functioning of ecosystems, such as the reduction of biodiversity. Phytoplankton are among the first to respond to these changes.

Planktonic Cyanobacteria of the tropical karstic lake Lagartos from the Yucatan Peninsula, Mexico

Revista de Biología Tropical, 2013
The tropical karstic lakes on the Mexican Caribbean Sea coast are numerous. However, there is an enormous gap of knowledge about their limnological conditions and micro-algae communities. In the present study, surface water samples were collected monthly

Nitrate, water temperature, conductivity, and transparency drive littoral phytoplankton species composition and biovolume in two reservoirs in the Xingu river

Water Biology and Security
Ecological interactions in the littoral zone maintain water quality, biodiversity, and ecological services in freshwater ecosystems. Phytoplankton occupy a central position in the ecosystem due to their sensitivity to environmental changes and ecological

Quantitative diatom metabarcoding : a correction factor inferred from cell biovolume

, 2017
DNA metabarcoding combined to high-throughput sequencing (HTS) is a promising approach for freshwater biomonitoring using benthic diatoms. This molecular approach is becoming faster, cheaper and allows handling more samples than the classical ...

Inter-operator precision in volume estimates for callipers and BioVolume.

, 2019
Volume estimates for BioVolume correspond to spheroid (the same formula as that used for callipers, in yellow) and cylindrical approximations (in red). Calliper data (in blue) is split into values from the BioVolume evaluation (left) and values from the ...

Lack of correlation between in vitro and within patient measures of P. aeruginosa biofilms in cystic fibrosis

Heliyon
Current in vitro biofilm modelling of the opportunistic pathogen, Pseudomonas aeruginosa (PA) in people with cystic fibrosis (PwCF) is limited in its ability to mimic the complexities of the cystic fibrosis (CF) lung environment.

Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

Ecosphere
Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the ...
