Estimation of Cyanobacteria Biovolume in Water Reservoirs by MERIS Sensor
Water Research, 2014 Planktonic cyanobacteria primarily develop in lentic water bodies, such as lakes and water reservoirs. In certain instances, toxin-producing cyanobacterial populations might dominate the phytoplankton community. Satellite remote sensing is a useful tool for large spatial scale monitoring of cyanobacteria, and the MERIS sensor from the Envisat satellite

Change in Cyanobacterial Biovolume Due to Preservation by Lugol's Iodine
Harmful Algae, 2005Cyanobacterial biovolume is used as a guide to the public health risk from these organisms for users of potable and recreational waters. Most routine surveillance programs preserve phytoplankton samples before analysis. We tested the effect of Lugol’s Iodine, a common preservative, on the cell biovolume of four common freshwater cyanobacteria ...

Bacterial carbon biomass calculated from biovolumes
Fundamental and Applied Limnology, 1998A conversion factor (CF) for the transformation of bacterial biovolumes to carbon biomass was calculated from measurements of particulate organic carbon (POC) and bacterial biovolumes (BV) in a large number of bacterial growth experiments from both freshwater and marine systems.

Biovolume and Biomass Estimates of Key Diatoms in the Southern Ocean [PDF]
Aquatic Microbial Ecology, 2007 Linear measurements of 31 Southern Ocean diatom species or genus groupings are pre- sented and used in the derivation of species-specific biovolume, biomass and surface to volume ratios. Species measurements are in tune with summarised values in the literature and range from 2.6 to 2296 µm in length and 8.5 to 140 µm in diameter.

Digital Holographic Microscopy for Microalgae Biovolume Assessment
Optics Communications, 2015 Abstract The relative amount of biomass in a body of water is one of the various indicators widely used in water quality evaluation. This implies complex tasks such as identification and characterization of microorganisms and measurement of their biovolume.

Improved biovolume estimation of Microcystis aeruginosa colonies: A statistical approach
Journal of Microbiological Methods, 2018The Microcystis aeruginosa complex (MAC) clusters many of the most common freshwater and brackish bloom-forming cyanobacteria. In monitoring protocols, biovolume estimation is a common approach to determine MAC colonies biomass and useful for prediction purposes.

Cyanobacteria samples: preservation, abundance and biovolume measurements
2016Estimating the occurrence, cell concentration, and biomass of cyanobacteria in natural samples is a fundamental requirement to assess potential risks linked to cyanobacterial bloom events. Special attention should be given to ensure that a reliable sampling technique is used.

Biovolume as a tool in biomass determination of Oligochaeta and Chironomidae
Freshwater Biology, 1993SUMMARY We used biovolume as a simple non‐destructive means for estimating biomass for several tubificid and chironomid species. Biovolumes were determined by treating the organisms as cylinders and measuring body lengths and diameters; estimates were verified by measuring the displacement of water by live organisms in a 5‐ml burette.

Methods for the estimation of the biovolume of microorganisms: A critical review
Limnology and Oceanography: Methods, 2017AbstractBiomass estimation is central in most microbial plankton ecology studies. Numerous advances have been made that rendered this task more and more effective, from the introduction of allometric volume‐to‐carbon conversion factors to the development of submersible flow‐through imaging devices. Although several ingenious methods have been suggested

The Significance of Hyphal Diameter in Calculation of Fungal Biovolume
Oikos, 1979Three ways to calculate average hyphal cross section in agarfilm slides were compared in a field study including 5 soil horizons sampled 4 times. The method of calculation strongly affected the estimated value for soil fungal biovolume. Biovolume estimated with the different methods varied by more than 30%.
