Despite accumulating evidence on the impact of global climate warming on marine microbes, how increasing seawater temperature influences the marine bacterioplankton communities is elusive. As temperature gradient created by thermal discharges provides a suitable in situ model to study the influence of warming on marine microorganisms, surface seawater were sampled consecutively for one year (September-2016 to August-2017) from the control (unimpacted) and thermal discharge-impacted areas of a… 

Effect of Various Local Anthropogenic Impacts on the Diversity of Coral Mucus-Associated Bacterial Communities

The results demonstrated the existence of bacterial isolates with antibacterial activity that possibly acted as a first line of defense to protect and maintain the coral host against pathogens.

Exploring bacterioplankton communities and their temporal dynamics in the rearing water of a biofloc-based shrimp (Litopenaeus vannamei) aquaculture system

It is observed that certain bacterioplankton groups dominated in a culture-stage-specific manner; these groups include Rhodobacteraceae, Flavobacteriaceae, Actinobacteria, and Chloroflexi, which either contribute to water quality regulation or possess probiotic potential.

Temperature Affects Antagonism Among Coral-Associated Bacteria

The antagonistic interaction network was nested and sender-determined both at 25°C and 32°C, suggesting that the competition networks of coral-associated bacteria were more influenced by the antagonist strains than sensitive strains, and the elevated temperature increased the complexity of the antagonistic network.

Bacterial community structure of early-stage biofilms is dictated by temporal succession rather than substrate types in the southern coastal seawater of India

The results refute the common assumption that substrate material has a decisive impact on biofilm formation; rather, it portrayed that the temporal succession overshadowed the influence of the substrate material.



Thermal discharge-created increasing temperatures alter the bacterioplankton composition and functional redundancy

It is demonstrated that elevated temperature, combined with substrate supply and trophic interactions, dramatically alters bacterioplankton community compositions, concomitant with decreases in functional redundancy.

Consequences of increased temperature and acidification on bacterioplankton community composition during a mesocosm spring bloom in the Baltic Sea.

Evaluation of the combined effects of temperature and acidification is necessary to fully understand consequences of climate change for marine bacterioplankton, their implications for future spring bloom dynamics, and their role in ecosystem functioning.

Warming and nutrient enrichment in combination increase stochasticity and beta diversity of bacterioplankton assemblages across freshwater mesocosms

The study suggests that the synergetic effects of warming and nutrient enrichment may result in high variability in the composition of bacterioplankton communities in lacustrine water bodies.

Lake microbial communities are resilient after a whole-ecosystem disturbance

Though overall ecosystem conditions remained altered, bacterial communities returned to their pre-manipulation state as some environmental conditions, such as oxygen concentration, recovered.


Responses of these benthic communities to ocean warming were mostly unpredicted and strongly coupled to direct effects of temperature on key taxa and indirect effects operating through ecological interactions, particularly habitat-forming subtidal kelps and intertidal foliose red algae.

Bacterioplankton Metacommunity Processes across Thermal Gradients: Weaker Species Sorting but Stronger Niche Segregation in Summer than in Winter in a Subtropical Bay

High-throughput sequencing of the 16S rRNA gene is used to examine marine bacterioplankton metacommunity assembly across thermal gradients in two representative seasons in a subtropical bay located on the northern coast of the South China Sea and found high heterogeneity in bacteriop lankton community compositions (BCCs) across thermalGradients and between seasons.

Sensitivity of Bacterioplankton to Environmental Disturbance: A Review of Baltic Sea Field Studies and Experiments

Bacterioplankton communities regulate energy and matter fluxes fundamental to all aquatic life. The Baltic Sea offers an outstanding ecosystem for interpreting causes and consequences of

Transplant experiments uncover Baltic Sea basin-specific responses in bacterioplankton community composition and metabolic activities

It is inferred that priming effects on bacterial community structure by natural episodic events or climate change induced forcing could translate into long-term changes in bacterial ecosystem process rates.

The Pattern of Change in the Abundances of Specific Bacterioplankton Groups Is Consistent across Different Nutrient-Enriched Habitats in Crete

The results provide an in situ indication concerning the association of specific bacterioplankton groups with nutrient enrichment and could potentially be used as indicators for nutrient enrichment if the pattern is confirmed over a broader spatial and temporal scale by future studies.

Long-term warming effects on the microbiome and nitrogen fixation of a common moss species in sub-Arctic tundra

Analysis of the total and potentially active bacterial community associated with Racomitrium lanuginosum in response to 20-year in situ warming in an Icelandic heathland suggests that the moss microbial community including the potentially nitrogen-fixing taxa is sensitive to future warming.
