Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2017 Phytoplankton biovolume and concentration of chlorophyll a are of major concerns in estimating the primary production in aquatic ecosystems. The objective of the present study was to estimate the concentration of chlorophyll a and its relation to ...

Marine Ecology, EarlyView., 2023 Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Bacterial Biovolume and Biomass Estimations [PDF]
Applied and Environmental Microbiology, 1985 The biomass of bacterial populations in aquatic ecosystems is often estimated by measuring bacterial biovolume and converting this into biomass in terms of carbon. A reliable conversion factor relating the measured bacterial biovolume to bacterial carbon content is essential for this approach. Based on direct measurements of bacterial cell

Relationships between Biovolume and Biomass of Naturally Derived Marine Bacterioplankton [PDF]
Applied and Environmental Microbiology, 1987 Microscopic estimation of bacterial biomass requires determination of both biovolume and biovolume-to-biomass conversion. Both steps have uncertainty when applied to the very small bacteria typically found in natural seawater. In the present study, natural bacterioplankton assemblages were freshly collected, passed through 0.6-μm-pore-size

Copepod Feeding Responses to Changes in Coccolithophore Size and Carbon Content
Journal of Marine Science and Engineering, 2022 Phytoplankton stoichiometry and cell size could result from both phenology and environmental change. Zooplankton graze on primary producers, and this drives both the balance of the ecosystem and the biogeochemical cycles.
