Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.

Diverse sophisticated phylogenetic analyses update the phylogeny of the Alphaproteobacteria and show that the parasitic Holosporales is a derived group within the Rhodospirillales order which comprises primarily free-living alphaproteobacteria.

Both beneficial and pathogenic bacteria can use their sheathed flagella during host colonization as a novel toxin-/signal-delivery mechanism.

Coral reef heterotrophic bacteria and fleshy macroalgae cause oxygen loss from reef systems through microbial biomass accumulation and ebullition from algae surfaces.
