Microbial Diversity in Modern Stromatolites

Poised at the biosphere–lithosphere interface, the microbial consortia associated with stromatolites have a profound impact on the evolution of Earth’s environment. In this chapter, we review the current state of knowledge of microbial diversity in extant stromatolites by examining data generated using cultivationindependent molecular techniques. Specifically, we compare natural stromatolitic m...

Composition and structure of microbial communities from stromatolites of Hamelin Pool in Shark Bay, Western Australia.

Stromatolites, organosedimentary structures formed by microbial activity, are found throughout the geological record and are important markers of biological history. More conspicuous in the past, stromatolites occur today in a few shallow marine environments, including Hamelin Pool in Shark Bay, Western Australia. Hamelin Pool stromatolites often have been considered contemporary analogs to anc...

Microbial Sedimentology of Stromatolites in Neoproterozoic Cap Carbonates

—Stromatolite shapes, sizes, and spacings are products of microbial processes and interactions with topography, sedimentation, and flow. Laboratory experiments and studies of modern microbial mats and sediments can help reconstruct processes that shaped some typical stromatolite forms and some atypical microbially influenced sediments from Neoproterozoic cap carbonates. Studies of modern, cohes...

Stratified Bacterial Diversity along Physico-chemical Gradients in High-Altitude Modern Stromatolites

At an altitude of 3,570 m, the volcanic lake Socompa in the Argentinean Andes is presently the highest site where actively forming stromatolite-like structures have been reported. Interestingly, pigment and microsensor analyses performed through the different layers of the stromatolites (50 mm-deep) showed steep vertical gradients of light and oxygen, hydrogen sulfide and pH in the porewater. G...

The Nature of Stromatolites: 3,500 Million Years of History and a Century of Research

Stromatolites are widely regarded as layered, early lithified, authigenic microbial structures – often domical or columnar in form – that developed at the sediment water interface in freshwater, marine and evaporitic environments (Fig. 1). In addition to this unusually wide environmental distribution, the exceptionally long geological record of stromatolites spans at least 3,500 million years (...
