Bacterial Cytochrome C Orchestrates Larval Metamorphosis Through Bioelectrical Control of Extracellular Vesicles Biogenesis

Journal of Extracellular Vesicles, Volume 15, Issue 10, October 2026.
The ccmH‐encoded CytC serves as a bioelectrical driver, facilitating EV production and orchestrating biofilm‐mediated larval metamorphosis. ABSTRACT Beyond the well‐established roles in biomedical processes, extracellular vesicles (EVs) from Gram‐negative bacteria are now identified as potent inducers of larval metamorphosis in marine invertebrates, a ...

Improving Micro– and Macro–Algae Speciation Mapping for Management: A Field‐Validated Sentinel‐2 and Sentinel‐3 Intercomparison in the Indian River Lagoon [PDF]

Geohealth
Abstract In recent years, the health of the Indian River Lagoon (IRL) on Florida's east coast has fluctuated due to recurring harmful algal blooms (HABs). These events typically involve cyanobacteria, dinoflagellates, or A. lagunensis (brown tide) causing water‐quality degradation and seagrass decline.

Drivers of metabolic density‐dependence: how resource availability and conspecific cues affect phytoplankton metabolism

Oikos, Volume 2026, Issue 10, October 2026.
Metabolism is density‐dependent from unicellular to multicellular organisms. Understanding what drives metabolic suppression is important to explain population growth given the link between metabolism and biomass production. In the simplest scenario, metabolic suppression is caused by a reduction in resource availability with increasing population ...

Phytoplankton biovolume estimation with conventional flow cytometry

Botanica Marina
Abstract Flow cytometry is widely used to assess phytoplankton populations, yet opportunities remain to improve and simplify the extraction of ecologically meaningful cellular properties such as biovolume. We assessed the relationship between microscopy measurements and flow cytometry signals in phytoplankton ...

Functional Identity Drives Directional Shifts in Freshwater Plankton Biomass–Size Relationships

Ecology Letters, Volume 29, Issue 10, October 2026.
Normalized biomass size spectra (NBSS) for four plankton functional groups across 588 Canadian lakes. Colours correspond to each functional group; points represent the mean normalized biomass for each size bin aggregated across all lakes, ranging from 0.1 to 3.5 μm.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

Fisheries Management and Ecology, Volume 33, Issue 5, Page 949-962, October 2026.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

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

Non‐Native Species Alter Functional Diversity Worldwide: A Systematic Review of Competition, Predation and Habitat‐Mediated Effects in Freshwater Ecosystems

Freshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The introduction of non‐native species is one of the main threats to biodiversity and ecosystem functioning in freshwater environments, affecting the functional diversity of native communities. Functional diversity, based on phenological, physiological and morphological traits, is a crucial tool for understanding community structure and ...

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.
