Active non-redundancy and viral orchestration sustain diel microbial successions in the coastal ocean

The paper reveals deterministic microbial succession in coastal oceans driven by active non-redundancy and viral orchestration, using metatranscriptomic data from Daya Bay.

Large temperature excursions have modest impacts on community composition in the high diversity gut microbiome of omnivorous American cockroaches (Periplaneta americana)

This study examines the impact of temperature changes on the gut microbiome of American cockroaches, finding modest effects with increased variability and shifts in specific bacterial taxa.

Niche specialization and cross-feeding interactions shaping gut microbial fiber degradation in a model omnivore

This study investigates how gut microbial communities in cockroaches degrade xylan and cellulose using synthetic diets and identifies niche specialization and cross-feeding interactions.

Genome Report: Improved chromosome-level genome assembly of the American cockroach, Periplaneta americana

The paper presents a high-quality chromosome-level genome assembly of the American cockroach, Periplaneta americana, using PacBio and Hi-C data, improving upon previous incomplete references.

Purified fibers in chemically defined synthetic diets destabilize the gut microbiome of an omnivorous insect model

The paper shows that purified fibers in synthetic diets reduce gut microbial diversity and alter phylogenetic composition in cockroaches, compared to whole-food diets.

Metabolic flexibility among fiber degraders supports gut microbiome stability across host diets in the American cockroach

This study shows that fiber-degrading microbes in cockroaches adjust their metabolism based on diet, using host glycans when fiber is scarce, maintaining gut microbiome stability.
