Cyanobacterial construction of hot spring siliceous stromatolites in Yellowstone National Park.
Living stromatolites growing in a hot spring in Yellowstone National Park are composed of silica-encrusted cyanobacterial mats. Two cyanobacterial mat types grow on the stromatolite surfaces and are preserved as two distinct lithofacies. One mat is present when the stromatolites are submerged or at the water-atmosphere interface and the other when stromatolites protrude from the hot spring. The...
متن کاملMolecular diversity of cyanobacteria inhabiting coniform structures and surrounding mat in a Yellowstone hot spring.
Lithified coniform structures are common within cyanobacterial mats in Yellowstone National Park hot springs. It is unknown whether these structures and the mats from which they develop are inhabited by the same cyanobacterial populations. Denaturing gradient gel electrophoresis and sequencing and phylogenetic analysis of 16S rDNA was used to determine whether (1) three different morphological ...
متن کاملAggregation Phenomena in Cyanobacterial, Stromatolite Analogues
Earth’s biological history is largely the story of microbial evolution. If one is to understand the evolution of such fundamental processes as photosynthesis, it is imperative to recognize and interpret microbial fossils. To these ends, we examine the forces that shape a modern cyanobacterial mat from the hot springs of Yellowstone that is thought to grow in a manner similar to an ancient struc...

However, mechanisms that create shore-parallel, m-scale elongated stromatolite mounds in carbonate sand are not well un...
متن کاملNew multi-scale perspectives on the stromatolites of Shark Bay, Western Australia.
A recent field-intensive program in Shark Bay, Western Australia provides new multi-scale perspectives on the world's most extensive modern stromatolite system. Mapping revealed a unique geographic distribution of morphologically distinct stromatolite structures, many of them previously undocumented. These distinctive structures combined with characteristic shelf physiography define eight 'Stro...
