Olive Tree Biovolume from UAV Multi-Resolution Image Segmentation with Mask R-CNN [PDF]
Sensors, 2021 Olive tree growing is an important economic activity in many countries, mostly in the Mediterranean Basin, Argentina, Chile, Australia, and California. Although recent intensification techniques organize olive groves in hedgerows, most olive groves are ...

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

Algorithm to estimate cell biovolume using image analyzed microscopy [PDF]
Cytometry, 1989 AbstractThis paper describes an algorithm for calculating the biovolume of cells with simple shapes, such as bacteria, flagellates, and simple ciliates, from a 2‐dimensional digital image. The method can be adapted to any image analysis system which allows access to the binary cell image—(i.e.), the pixels, or (x, y) points, composing the cell.

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

Using light scatter signal to estimate bacterial biovolume by flow cytometry [PDF]
Cytometry, 2001 In the past decade, flow cytometry has become a useful and precise alternative to microscopic bacterial cell counts in aquatic samples. However, little evidence of its usefulness for the evaluation of bacterial biovolumes has emerged in from the literature.The light scattering and cell volume of starved bacterial strains and natural bacterial ...

Plankton abundance, biovolume, and normalized biovolume size spectra in the northern slope of the South China Sea in autumn 2014 and summer 2015 [PDF]
Deep Sea Research Part II: Topical Studies in Oceanography, 2019 Abstract Plankton abundance, biovolume and distribution in the northern slope of the South China Sea in summer 2015 and autumn 2014 were assessed by using flow cytometry and microscopy (FlowCAM) and ZooScan methods. Copepoda was the most dominant zooplankton in both seasons. Rhizosolenia dominated the phytoplankton community in autumn. In summer, the

Seasonal dynamics of an aquatic macroinvertebrate assembly (Hydrobiological case study of Lake Balaton No. 2) [PDF]
, 2007 In 2002, 2003 and 2004, we took macoinvertebrate samples on a total of 36 occasions at the Badacsony bay of Lake Balaton. Our sampling site was characterised by areas of open water (in 2003 and 2004 full of reed-grass) as well as by areas covered by ...

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.
