  Community composition drives siderophore dynamics in multispecies bacterial communities. 

  O'Brien, Siobhan (2023)

  Background Intraspecific public goods are commonly shared within microbial populations, where the benefits of public goods are largely limited to closely related conspecifics. One example is the production of iron-scave ...

  Ecological selection of siderophore-producing microbial taxa in response to heavy metal contamination 

  O'Brien, Siobhan (2018)

  Some microbial public goods can provide both individual and community-wide benefits, and are open to exploitation by non-producing species. One such example is the production of metaldetoxifying siderophores. Here, we ...

  No effect of intraspecific relatedness on public goods cooperation in a complex community 

  O'Brien, Siobhan (2018)

  Many organisms—notably microbes—are embedded within complex communities where cooperative behaviors in the form of excreted public goods can benefit other species. Under such circumstances, intraspecific interactions are ...

  Transposable temperate phages promote the evolution of divergent social strategies in Pseudomonas aeruginosa populations 

  O'Brien, Siobhán (2019)

  Transposable temperate phages randomly insert into bacterial genomes, providing increased supply and altered spectra of mutations available to selection, thus opening alternative evolutionary trajectories. Transposable ...

  Cultivating antimicrobial resistance: how intensive agriculture ploughs the way for antibiotic resistance 

  O'Brien, Siobhan (2023)

  Antimicrobial resistance (AMR) is a growing threat to public health, global food security and animal welfare. Despite efforts in antibiotic stewardship, AMR continues to rise worldwide. Anthropogenic activities, particularly ...
