Low Abundance Taxa Show Diverse Microbial Symbiotic Interactions With the Freshwater Sponge, Radiospongilla crateriformis, Pre and Post Gemmulation

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
The microbiome profile of freshwater sponges did not broadly change in taxonomy or functional profile based on metatranscriptome analysis prior to and after formation of sponge dormant bodies (gemmules). Results highlight a subset of taxa that likely associate with the sponge host in different ways from facultative to long‐term symbionts.

Distinct water mass between inside and outside eddy drive changes in prokaryotic growth and mortality in the tropical Pacific Ocean

Frontiers in Marine Science
Throughout the western tropical Pacific Ocean, eddies and currents play an important role in biogeochemical cycling. Many studies have investigated the effects of hydrography on vertical patterns of picophytoplankton and heterotrophic bacterial abundance

Spatio-temporal behaviour of the deep chlorophyll maximum in Mediterranean Sea: Development of a stochastic model for picophytoplankton dynamics [PDF]

, 2013
In this paper, by using a stochastic reaction-diffusion-taxis model, we analyze the picophytoplankton dynamics in the basin of the Mediterranean Sea, characterized by poorly mixed waters.

Dynamics of Microbial Abundance in Unvegetated and Seagrass Habitats: A Case Study

Journal of Marine Science and Engineering
Seagrass meadows are recognized for their ecological importance, yet their influence on microbial community structure remains insufficiently characterized.

Intercomparison of Ocean Color Algorithms for Picophytoplankton Carbon in the Ocean

Frontiers in Marine Science, 2017
The differences among phytoplankton carbon (Cphy) predictions from six ocean color algorithms are investigated by comparison with in situ estimates of phytoplankton carbon.

Photoacclimation of picophytoplankton in the central Cantabrian Sea

Marine Ecology Progress Series, 2013
Photoacclimation of picophytoplankton was studied in the mixed layer of 3 stations in the central Cantabrian Sea (southern Bay of Biscay). Picophytoplankton chl a:carbon ratios (θ) presented minimum values during summer, when irradiance, temperature, and biomass of prokaryotes reached maximum values and inorganic nutrient concentrations were low ...

Temperature-Dependent Photoregulation in Oceanic Picophytoplankton During Excessive Irradiance Exposure [PDF]

, 2013
The phytoplankton community of open oligotrophic oceans is dominated by prokaryotic Prochlorococcus spp., Synechococcus spp., and eukaryotic picoand nanophytoplankton [1-3]. The competitive success of these phytoplankton species depends on different factors, including the response to the (dynamic) irradiance conditions encountered in the water column ...

Orchestrated transcription of biological processes in the marine picoeukaryote Ostreococcus exposed to light/dark cycles [PDF]

, 2010
Background: Picoeukaryotes represent an important, yet poorly characterized component of marine phytoplankton. The recent genome availability for two species of Ostreococcus and Micromonas has led to the emergence of picophytoplankton comparative ...

Utilizing Exhaled Breath and Skin Microbiomes in Assessments of At‐Risk Killer Whales (Orcinus orca)

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT For at‐risk populations of killer whales (Orcinus orca), biological samples can offer information about individual animal status. We hypothesized that low‐yield samples could provide sufficient material for microbiome analysis. We collected and analyzed, with amplicon metabarcoding, breath samples from managed care and free‐ranging killer ...

Modeling selective pressures on phytoplankton in the global ocean. [PDF]

PLoS ONE, 2010
Our view of marine microbes is transforming, as culture-independent methods facilitate rapid characterization of microbial diversity. It is difficult to assimilate this information into our understanding of marine microbe ecology and evolution, because ...
