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.

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.

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.

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

Cyanobacterial samples: preservation, enumeration, and biovolume measurements
2017Estimating 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.

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%.

Digital holography as a method for 3D imaging and estimating the biovolume of motile cells
Lab on a Chip, 2013Sperm morphology is regarded as a significant prognostic factor for fertilization, as abnormal sperm structure is one of the most common factors in male infertility. Furthermore, obtaining accurate morphological information is an important issue with strong implications in zoo-technical industries, for example to perform sorting of species X from ...

Respiration rates and biovolumes of common benthic Foraminifera (Protozoa)
Journal of the Marine Biological Association of the United Kingdom, 1994The respiration rates of five genera of benthic Foraminifera were determined by Cartesian diver microrespirometry. Across all genera studied, the rate averaged 11·3×10−3μl O2individual−1h−1at 10°C. Estimates of foraminiferal mean biovolumes ranged from 0·66 to 6·54×106μm3, giving an overall mean volume-specific respiration rate of 7·36 × 10−9μl O2h−1μm−

Effects of eutrophication on diatom abundance, biovolume and diversity in tropical coastal waters
Environmental Monitoring and Assessment, 2017Diatom abundance, biovolume and diversity were measured over a 2-year period along the Straits of Malacca at two stations with upper (Klang) and lower (Port Dickson) states of eutrophication. Diatom abundance, which ranged from 0.2 × 104 to 21.7 × 104 cells L-1 at Klang and 0.9 × 103- 41.3 × 103 cells L-1 at Port Dickson, was influenced partly by ...
