Cold‐water coral ecosystems under future ocean change: Live coral performance vs. framework dissolution and bioerosion
(Limnology and Oceanography, 2022-09-10)Physiological sensitivity of cold‐water corals to ocean change is far less understood than of tropical corals and very little is known about the impacts of ocean acidification and warming on degradative processes of dead ... -
Coleoidenreste aus der Oberkreide des Libanon im Staatlichen Museum für Naturkunde in Stuttgart

Coleoids from the Lower Devonian Black Slate ("Hunsrück-Schiefer") of the Hunsrück (West Germany)
(Neues Jahrbuch für Geologie und Paläontologie. Abhandlungen, 1983)Three new genera of endocochleate cephalopods from the Lower Devonian cast new light on the evolution of modern and fos sil coleoids. Protoaulacoceras n. g. represents the r03trum-bearing line of aulacocerid-belemnitid ... -

Comment on ‘Kidron, G. J. (2018). Biocrust research: A critical view on eight common hydrological-related paradigms and dubious theses. Ecohydrology, e2061’
(Ecohydrology, 2020)According this discussion the eight putative paradigms advanced by Kidron (2018) cannot be upheld nor are they commonly held among hydrologists, ecologists, or microbiologists that investigate biocrusts. -
Comparing surface digitization techniques in palaeontology using visual perceptual metrics and distance computations between 3D meshes
(Palaeontology, 2021-01-17)The use of surface digitization techniques and methods in palaeontology has increased in the last two decades, mainly due to recent improvements in devices and software. However, many digitization efforts are published ... -
Comparison of biocalcification processes in the two coralline demosponges Astrosclera willeyana Lister 1900 and "Acanthochaetetes"; wellsi Hartman and Goreau 1975
(Proceedings of the eighth International Coral Reef Symposium, Panama, June 24-29,1996, 1997) -
Conch geometry, ontogeny and dimorphism in the Early Bajocian ammonoid Stephanoceras from Normandy, France
(Lethaia, 2021-07-22)A large suite of specimens belonging to the Early Bajocian Stephanoceras from Évrecy (Normandy, France) displays wide variation in conch and sculpture. The quantitative analysis of the conch geometry and its ontogeny on ... -
Concretionary methane-seep carbonates and associated microbial communities in Black Sea sediments
(Palaeogeography, Palaeoclimatology, Palaeoecology, 2005)Gas seeps in the euxinic northwestern Black Sea provide an excellent opportunity to study anaerobic, methane-based ecosystems with minimum interference from oxygen-dependent processes. An integrated approach using fluorescence- ... -
Contrasting Global Patterns of Spatially Periodic Fairy Circles and Regular Insect Nests in Drylands
(Journal of Geophysical Research: Biogeosciences, 2019)Numerical analysis of spatial pattern is widely used in ecology to describe the characteristics of floral and faunal distributions. These methods allow attribution of pattern to causal mechanisms by uncovering the specific ... -
Coralline demosponges - a geobiological portrait

Coralline demosponges ; a geobiological portrait
(Bulletin / The Tohoku University Museum, 2001)The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One extant taxon of each skeletal type has ... -

Countergradient variation concealed adaptive responses to temperature increase in Daphnia from heated lakes
(Limnology and Oceanography, 2020-12-21)To test the general assumption that global warming will induce body size reduction in aquatic organisms, we used a system of lakes continually heated for six decades by warm water discharge from power plants. Their temperature ... -
Coupled changes in traits and biomasses cascading through a tritrophic plankton food web
(Limnology and Oceanography, 2020)Trait-based approaches have broadened our understanding of how the composition of ecological communities responds to environmental drivers. This research has mainly focussed on abiotic factors and competition determining ... -
Cryptogamic organisms are a substantial source and sink for volatile organic compounds in the Amazon region
(Communications Earth & Environment, 2021-12-21)Cryptogamic organisms such as bryophytes and lichens cover most surfaces within tropical forests, yet their impact on the emission of biogenic volatile organic compounds is unknown. These compounds can strongly influence ... -
Current extinction rate in European freshwater gastropods greatly exceeds that of the late Cretaceous mass extinction
(Communications Earth & Environment, 2021-05-21)The Cretaceous–Paleogene mass extinction event 66 million years ago eradicated three quarters of marine and terrestrial species globally. However, previous studies based on vertebrates suggest that freshwater biota were ...
