New geometric models for calculation of microalgal biovolume [PDF]
Brazilian Archives of Biology and Technology, 2011 Biovolume calculation of micro algae is commonly used for the assessment in relative abundance (as biomass or carbon) of coexistent algae that vary in shape and/or size. Periphyton samples were obtained within a more general program, in fishery tanks and

Rivers affect the biovolume and functional traits of phytoplankton in floodplain lakes [PDF]
Acta Limnologica Brasiliensia, 2017 Aim: We analyzed the temporal distribution (dry and rainy periods) of phytoplankton functional groups (biovolume) from lakes connected to dammed (S1 - Paraná River) and non-dammed rivers (S2 - Baia River and S3 - Ivinhema River) in the upper Paraná River

Carbon and nitrogen content to biovolume relationships for marine protist of the Rhizaria lineage (Radiolaria and Phaeodaria) [PDF]
Limnology and Oceanography, 2021 Rhizaria are large protistan cells that have been shown to be a major component of the planktic community in the oceans and contribute significantly to major biogeochemical cycles such as carbon or silicon.

Similar growth potentials of cyanobacteria and algae explain their coexistence in desert soils [PDF]
Scientific ReportsIn deserts that cover one-third of the Earth’s terrain, soil cyanobacteria and algae are key carbon dioxide (CO2) fixers because few other plants can tolerate intense solar radiation, prolonged desiccation, and extreme temperature shifts.
