Phototrophic biofilms of the Kachelotplate were studied to assess their role in sediment stabilization. At most sampling stations the surficial sediment was dominated by diatoms with occasional cyanobacterial unicells and filaments interspersed. Cohe

Microbial mats are widespread biotic systems in Tunisian coastal sabkhas. In these environments, staphilinid beetles are important bioturbators, making vertical burrows and depositing characteristic hillocks of excavation pellets on the mat surface.

Vertical sequences in modern siliciclastic sediments are used to document the intimate relationship between sedimentation rates and frequency and the development of microbial mats of different successional stages that correspond with hiatal intervals

Enigmatic discoidal fossils are common in Neoproterozoic sedimentary sequences and in the stratigraphic record pre-date the first appearance of diverse Ediacaran fossil assemblages. Termed ‘medusoids’, these Neoproterozoic discoidal fossils have

Sessile Meerestiere stellen “belebte” marine Substrate dar, auf denen Biofilme ausgebildet sein konnen. Neben anderen Bryozoenarten ist auch das Blattermoostierchen Flustra foliacea ein Beispiel dafur, dass die Wirte die Bedingungen fur ihren Bio

Laminar bryozoans of shallow marine sites from cool-temperate to subtropical climate in Japan and New Zealand tolerated mainly agglutinated biofilms composed of diatoms, fungi, cyanobacteria and other bacteria as well as debris trapped in slimes. Als

Interdisciplinary studies carried out on marine and terrestrial deposits, such as tidal flats, lagoonal deposits, and salt marshes have provided the basis for interpreting Holocene sea-level fluctuations along the southern North Sea coast. Radiocarbo
