Corncob structures in dental plaque reveal microhabitat taxon specificity
Background The human mouth is a natural laboratory for studying how bacterial communities differ across habitats. Different bacteria colonize different surfaces in the mouth—teeth, tongue dorsum, and keratinized and non-keratinized epithelia—despite the ...

How many generations does it take for phytophages to colonize invasive plants? Mathematical modeling predictions [PDF]
Native phytophagous insects are often not adapted to novel chemistry of invasive plants, but over time they begin to adapt and feed on them. We simulated the spread of a mutant allele that enables phytophages to feed on invasive plant as efectively as on
