For more than 30 years, the association between the Hawaiian bobtail squid, Euprymna
scolopes, and the bioluminescent bacterium Vibrio fischeri has been studied as a model …

As our understanding of the human microbiome progresses, so does the need for natural
experimental animal models that promote a mechanistic understanding of beneficial …

Intraspecific competition describes the negative interaction that occurs when different
populations of the same species attempt to fill the same niche. Such competition is predicted …

Genetic diversity of closely related free-living microorganisms is widespread and underpins
ecosystem functioning, but most evolutionary theories predict that it destabilizes intimate …

Few animal groups can claim the level of wonder that cephalopods instill in the minds of
researchers and the general public. Much of cephalopod biology, however, remains …

The species Lactobacillus reuteri has diversified into host-specific lineages, implying a long-
term association with different vertebrates. Strains from rodent lineages show specific …

Strain diversity, while now recognized as a key driver underlying partner dynamics in
symbioses, is usually difficult to experimentally manipulate and image in hosts with complex …

Ocean ecosystems are experiencing unprecedented rates of climate and anthropogenic
change, which can often initiate stress in marine organisms. Symbioses, or associations …

Vibrio fischeri is used as a model for a number of processes, including symbiosis, quorum
sensing, bioluminescence, and biofilm formation. Many of these studies depend on …

Interbacterial competition is prevalent in host-associated microbiota, where it can shape
community structure and function, impacting host health in both positive and negative ways …
