Changes in the Trophic Pathways within the Microbial Food Web in the Global Warming Scenario: An Experimental Study in the Adriatic Sea

open access: yesMicroorganisms, 2020
A recent analysis of the Mediterranean Sea surface temperature showed significant annual warming. Since small picoplankton microorganisms play an important role in all major biogeochemical cycles, fluxes and processes occurring in marine systems (the ...

Critical knowledge gaps in the conservation and restoration of cold‐water corals

open access: yesRestoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Critical knowledge gaps hamper effective conservation of threatened cold‐water coral (CWC) ecosystems, facing cumulative anthropogenic and climate pressures. This review provides a strategic roadmap for urgent, informed intervention.

Abundance of coccoid cyanobacteria, hydrographic parameters and the possible underestimation of in situ chlorophyll a in the northern gulf of California and the Mexican California Current

open access: yesCiencias Marinas, 2000
The abundance of coccoid cyanobacteria was counted within the euphotic zone at a station in Delfín Basin, in the northern Gulf of California, and at a station in the California Current, off Todos Santos Bay, during 1993.

Inter-annual ciliate distribution variation within the late stratification oxycline in a monomictic lake, Lake Alchichica (Mexico) [PDF]

open access: yes, 2016
Deep stratified tropical water bodies pass through prolonged periods of meta-hypolimnetic anoxia, and ciliates might play a very important role in the plankton community budget there.

Nutrient availability modulates impacts of short‐term shifts in temperature and grazing on phytoplankton composition and size structure

open access: yesLimnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract The significant contribution of phytoplankton to global primary production is regulated by several abiotic and biotic factors, which are often difficult to account for in natural systems. To address these challenges, we perturbed a summer plankton community from Narragansett Bay, Rhode Island, USA, by manipulating the temperature and nutrient ...

Photosynthetic characteristics and diversity of freshwater Synechococcus at two depths during different mixing conditions in a deep oligotrophic lake [PDF]

open access: yes, 2007
We studied the photosynthetic characteristics and genetic diversity of Synechococcus assemblages at two different light and mixing conditions in a deep oligotrophic lake (Lake Maggiore, Northern Italy).

Zooplankton grazing and nutrient supply control the emergence of large diatoms in coastal upwelling systems: Insights from a regional ecosystem model

open access: yesLimnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract The California Current System (CCS) is characterized by dynamic coastal upwelling that profoundly influences plankton community structure and diversity and that leads to the emergence of large diatoms nearshore. This study presents a high‐resolution biogeochemical model of the CCS, coupling the Darwin ecosystem model with the Regional Ocean ...

Concentration-Dependent Patterns of Leucine Incorporation by Coastal Picoplankton [PDF]

open access: yesApplied and Environmental Microbiology, 2006
ABSTRACT Coastal pelagic environments are believed to feature concentration gradients of dissolved organic carbon at a microscale, and they are characterized by pronounced seasonal differences in substrate availability for the heterotrophic picoplankton.

A prototype submersible sheathless flow cytometer designed for autonomous platforms

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.
Abstract Development of submersible flow cytometers has allowed for continuous, in situ measurements of natural assemblages of phytoplankton cells. Here we introduce DeepCyte, a sensitive prototype submersible flow cytometer developed for deployment on autonomous platforms.
