The ubiquity of bacteriophages (phages) and the major evolutionary and ecological impacts they can have on their microbial hosts has resulted in phages often cited as key drivers shaping microbial community composition (the relative abundances of species). However, the evidence for the importance of phages is mixed. Here, we critically review the theory and data exploring the role of phages in communities, identifying the conditions when phages are likely to be important drivers of community composition. At ecological scales, we conclude that phages are often followers rather than drivers of microbial population and community dynamics. While phages can affect strain diversity within species, there is yet to be strong evidence suggesting that fluctuations in species' strains affects community composition.

Infected wound treatment remains a critical challenge in clinical medicine. Although existing treatments, like local debridement, antimicrobial agents, and growth factor therapies, have demonstrated certain therapeutic effects, they primarily target only specific stages of wound healing. Moreover, the escalating issue of antibiotic resistance limits their efficacy.

Silica nanoparticles (SiONPs), as emerging foliar nanofertilizers, demonstrate promising potential in agriculture. However, whether foliar application of SiONPs alters belowground soil metabolites and microbe composition and abundance remains largely unknown. In this study, 3-week-old cucumber plants were foliar-sprayed with fumed or Stöber SiO NPs dosing at -4 mg of NPs per plant for 5 days.

Droughts are increasing with climate change, affecting the functioning of terrestrial ecosystems and limiting their capacity to mitigate rising atmospheric CO levels. However, there is still large uncertainty on the long-term impacts of drought on ecosystem carbon (C) cycling, and how this determines the effect of subsequent droughts. Here, we aimed to quantify how drought legacy affects the response of a heathland ecosystem to a subsequent drought for two life stages of Calluna vulgaris resulting from different mowing regimes.

Background: The neonatal period is critical for oral microbiome establishment, but temporal patterns in preterm newborns remain unclear. This study examined longitudinal microbiome changes in full-term and preterm newborns and assessed perinatal and clinical influences.
Methods: Oral swabs were collected from 98 newborns (23 full-term, 75 preterm).

Biofouling poses significant ecological and operational challenges in marine environments, particularly across Indonesia's diverse tropical waters. It increases hydrodynamic drag on vessels, leading to greater fuel consumption and elevated operational costs. This review synthesizes both recent and historical studies to examine the taxonomic and functional diversity of marine biofouling organisms in Indonesian waters.
