We summarize different studies describing mechanisms through which bacteria in a biofilm
mode of growth resist mechanical and chemical challenges. Acknowledging previous …

It has long been recognized that biofilms are viscoelastic materials, however the importance
of this attribute to the survival and persistence of these microbial communities is yet to be …

The rock record contains a rich variety of sedimentary surface textures on siliciclastic
sandstone, siltstone and mudstone bedding planes. In recent years, an increasing number …

Biofilms are complex, self-organized consortia of microorganisms that produce a functional,
protective matrix of biomolecules. Physically, the structure of a biofilm can be described as …

Bacterial biofilms correspond to surface-associated bacterial communities embedded in
hydrogel-like matrix, in which high cell density, reduced diffusion and physico-chemical …

Biofilm activities and their interactions with physical, chemical and biological processes are
of great importance for a variety of ecosystem functions, impacting hydrogeomorphology …

Wrinkle structures on sandy bed surfaces were present in some of the earliest sedimentary
environments, but are rare in modern environments. These enigmatic millimetre-to …

To date, microbialites include five groups: stromatolites, thrombolites, leiolites, and
dendrolites. All these microbialites occur in carbonate or silica lithologies. However …

Abstract The Eastern Anti-Atlas of Morocco hosts an early Ediacaran turbiditic series
(Saghro Group)(630–600 Ma) unconformably overlain by thick late Ediacaran (580–550 Ma) …

Evidence for microbial mats has been reported repeatedly from marine Lower Triassic rocks,
but scarcely mentioned in post-mass extinction terrestrial facies. Here, we report from the …
