Microbial-, fusulinid limestones with large gastropods and calcareous algae: an unusual facies from the Early Permian Khao Khad Formation of Central Thailand
(Facies, 2020-07-14)The Early Permian (Kungurian) Khao Khad Formation of Central Thailand consists mostly of carbonates deposited on the western margin of the Indochina Terrane. This formation has yielded unusual microbial-fusulinid limestones ... -

Mid-chain branched alkanoic acids from "living fossil" demosponges: a link to ancient sedimentary lipids?
(Organic geochemistry, 1999)The lipid assemblages of the "living fossil" stromatoporoid Astrosclera willeyana (Great Barrier Reet) and the demosponge Agelas aroides (Mediterranean Sea) were investigated. Large amounts of branched carboxylic acids ... -
Mid‐ to late Holocene environmental changes and human‐environment interactions in the surroundings of La Silla del Papa, SW Spain
(Geoarchaeology, 2021-02-17)In southern Iberia, the surroundings of the Strait of Gibraltar are known as a crossroad for population movements, cultural exchanges, and trade from Late Prehistory to modern times. However, questions remain about the ... -
Mikrobialith-Porifera Fazies eines Exogyren/Korallen Patchreefs des Oberen Korallenooliths im Steinbruch Langenberg bei Oker (Niedersachsen)
(Berliner geowissenschaftliche Abhandlungen, 1994)Im oberen Korallenoolith (Oxford-Kimmeridge) von Oker entwickelten sich kleine lagunäre Riffe, deren Gerüst aus Exogyren, Serpeln und großen einzelnen Korallenstöcken gebildet wurde. Die umgebende Fazies besteht aus ... -
Millimetre scale aeration of the rhizosphere and drilosphere
(European Journal of Soil Science, 2022-07-06)Soil aeration is a critical factor for oxygen‐limited subsoil processes, as transport by diffusion and advection is restricted by the long distance to the free atmosphere. Oxygen transport into the soil matrix is highly ... -
Mixed Layer Depth Promotes Trophic Amplification on a Seasonal Scale
(Geophysical Research Letters, 2022-06-16)The Humboldt Upwelling System is of global interest due to its importance to fisheries, though the origin of its high productivity remains elusive. In regional physical‐biogeochemical model simulations, the seasonal amplitude ... -
Model simulation of seasonal growth of Fucus vesiculosus in its benthic community
(Limnology and Oceanography: Methods, 2020)Numerical models are a suitable tool to quantify impacts of predicted climate change on complex ecosystems but are rarely used to study effects on benthic macroalgal communities. Fucus vesiculosus L. is a habitat-forming ... -
Modern brackish bryostromatolites (“bryoliths”) from Zeeland (Netherlands)
(Palaeobiodiversity and Palaeoenvironments, 2021-06-17)Bryostromatolites are found in stressed environments from the Paleozoic to the Recent. They are formed by alternating layers of bryozoans and microbes. This study investigates recent bryostromatolites in brackish ponds in ... -
Modern cryptic microbialite/metazoan facies from Lizard Island (Great Barrier Reef, Australia) formation and concepts
(Facies, 1993)From shallow water caves of fringing reefs related to continental islands of the Lizard Island Section thrombolitic micritic microbialites were observed. The microbialites exhibit always a light decreasing facies ... -
Molecular and Morphological Evidence Challenges the Records of the Extant Liverwort Ptilidium pulcherrimum in Eocene Baltic Amber.
(PloS one, 2015)Preservation of liverworts in amber, a fossilized tree resin, is often exquisite. Twenty-three fossil species of liverworts have been described to date from Eocene (35-50 Ma) Baltic amber. In addition, two inclusions have ... -
Monophyly of the Porifera

Monophyly of the Porifera
(Verhandlungen des Naturwissenschaftlichen Vereins in Hamburg, 1996)The monophyly of the Porifera is weil established. According to our hypothesis the Hexactinellida are the adelphotaxon of the Pinacophora (new taxon = Calcarea + Homoscleromorpha + Demospongiae). The Porifera are the ... -
Morphology and ecological setting of the basal echinoid genus Rhenechinus from the early Devonian of Spain and Germany
(Acta Palaeontologica Polonica, 2012)ased on new material from Germany and Spain, the echinoid “Lepidocentrus” ibericus from the Early Devonian (Emsian) of northern Spain is shown to be congeneric with Rhenechinus from the Hunsrück Slate of south−western ... -
Multiclonal study of Daphnia magna with respect to adaptation to toxic cyanobacteria
(Limnology and Oceanography, 2023-01-13)Mass developments of toxic cyanobacteria have increased in frequency due to global warming and eutrophication. Such cyanobacterial blooms impact whole freshwater ecosystems, especially reducing the abundance of herbivory ...
