A Case Study on variation in biovolume of the phytoplanktonic flora.pdf

, 2021
A study was performed on phytoplanktonic flora, mainly diatoms,collected from the Hooghly estuarine area on the northeast coast of Bay ofBengal to observe the monthly and spatial variations in relative abundance,surface area of individual species, biovolume and total biovolume ofphytoplankton and the detailed effect of physico-chemical parameters ...

Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

Functional Ecology, Volume 40, Issue 8, Page 2475-2489, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

Rainfall increases the biomass and drives the taxonomic and morpho-functional groups variability of phytoplankton in a subtropical urban lake [PDF]

Acta Limnologica Brasiliensia
: Aim To explore the short-term effects of rainfall events on the biomass, density, and richness of the phytoplankton community during dry and rainy periods, as well as on the selection and response of Morphology-Based Functional Groups (MBFG). Methods

Acorn caching hotspots of the Eurasian jay in pine plantations: Ecological basis for understorey management to assist oak regeneration

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Our findings show that Eurasian jay dispersal activity depends on specific understorey structures when selecting caching microsites—particularly shrub cover and standing pines. These features could be directly shaped by management to promote assisted natural oak regeneration.

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

Distribution of periphytic algae in wetlands (Palm swamps, Cerrado), Brazil

Brazilian Journal of Biology
The distribution of periphytic algae communities depends on various factors such as type of substrate, level of disturbance, nutrient availability and light.

GcrR in Streptococcus mutans Inhibits the Morphological Transition of Candida albicans Through Ras1–cAMP/PKA Pathway in the Cross‐Kingdom Biofilms

Molecular Oral Microbiology, Volume 41, Issue 4, Page 188-200, August 2026.
ABSTRACT The dual‐species biofilms formed by Streptococcus mutans and Candida albicans exhibit enhanced cariogenic potential due to the production of extracellular polysaccharides (EPSs). The response regulator GcrR in S. mutans negatively regulates EPS synthesis, but its impact on dual‐species biofilms remains unclear.

Mapeamento do biovolume de plantas aquáticas submersas a partir de dados hidroacústicos e imagem multiespectral de alta resolução Mapping the bio-volume of submerged aquatic vegetation through hydro-acoustic data and high-resolution multi-spectral imaging

Planta Daninha, 2012
As plantas aquáticas têm papel fundamental no equilíbrio dos ecossistemas, porém seu crescimento desequilibrado pode obstruir canais, represas e reservatórios e afetar múltiplos usos da água.

Assessing Zooplankton Communities' Influence on Particulate Organic Carbon Concentration

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Zooplankton play a key role in setting the particulate organic carbon (POC) distribution in the ocean, but this role remains poorly quantified on large scales due to the complexity of zooplankton ecosystems and the sparsity and variability of observations.

Rapid and versatile routine measurements of plankton biovolumes with BACCHUS [PDF]

Journal of Plankton Research, 1999
A semi-automated biovolume measurement application called BACCHUS (Biovolume Analysis Cum Calculus and High Utility Statistics), based on an image-analysis program combined with a database, was developed. With this application, biovolumes of plankton taxa can be determined while counting routine samples.
