“…If the host provides an environment with the correct nutrients, pH and temperature for survival, then a microbe can occupy that environment in the gut, given that it can successfully compete with other gut microbes [58] (figure 1a). Owing to overlaps in microbial metabolisms, an ecological niche in the gut could be occupied by more than one organism [59], and a priority effect might exist, where the first organism to occupy a niche has a competitive advantage over following ones based on how it occupies the habitat [60][61][62][63]. Such ecological niches would be expected to have high variability in bacterial composition between individuals, consistent with the high degree of individuality seen in the human gut [61].…”

Gut bacteria are prevalent throughout the Metazoa and form complex microbial communities associated with food breakdown, nutrient provision and disease prevention. How hosts acquire and maintain a consistent bacterial flora remains mysterious even in the best-studied animals, including humans, mice, fishes, squid, bugs, worms and flies. This essay visits the evidence that hosts have co-evolved relationships with specific bacteria and that some of these relationships are supported by specialized physical niches that select, sequester and maintain microbial symbionts. Genetics approaches could uncover the mechanisms for recruiting and maintaining the stable and consistent members of the microbiome. This article is part of the theme issue ‘Sculpting the microbiome: how host factors determine and respond to microbial colonization’.
