In shallow ponds and lakes, anaerobic photoautotrophic bacteria occur on the surface of the sediment, often conferring characteristics colour on these water bodies. This indicates that the habitat specialist distribution across an environmental gradient does not necessarily reflect the one at the metacommunity level and that specialist taxa are not always rare taxa as previously hypothesized33.
