Predicting cyanobacterial biovolumes from phycocyanin fluorescence using a handheld fluorometer in the field

Harmful Algae, 2020
Toxic cyanobacterial blooms are becoming more prevalent in freshwater systems, increasing the need for monitoring to protect human health. Phycocyanin fluorescence sensors have been developed as tools for providing fast and cost-effective proxy measurements for cyanobacterial biomass.

New data‐driven method from 3D confocal microscopy for calculating phytoplankton cell biovolume

Journal of Microscopy, 2015
SummaryConfocal laser scanner microscopy coupled with an image analysis system was used to directly determine the shape and calculate the biovolume of phytoplankton organisms by constructing 3D models of cells. The study was performed on Biceratium furca (Ehrenberg) Vanhoeffen, which is one of the most complex‐shaped phytoplankton.

The Significance of Hyphal Diameter in Calculation of Fungal Biovolume

Oikos, 1979
Three 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%.

3D visualization and biovolume estimation of motile cells by digital holography

SPIE Proceedings, 2014
For the monitoring of biological samples, physical parameters such as size, shape and refractive index are of crucial importance. However, up to now the morphological in-vitro analysis of in-vitro cells has been limited to 2D analysis by classical optical microscopy such as phase-contrast or DIC. Here we show an approach that exploits the capability of

Prelimnary biovolume characterisation of zooplankton community in Omi Dam, Nigeria

2010
The study examined the zooplankton biomass in Omi dam to identify which specie(s) among the major ones under consideration, contributed most to the recruitment and growth of fish in the dam. Rotifera took the dominance in terms of species, followed by cladocerans and copepod respectively.
