Chironomiden als Anzeiger für die holozäne Klima- und Umweltgeschichte von Store Koldewey in Nordostgrönland
(Univ. Köln, 2009)Sedimentkerne aus zwei hocharktischen Seen (Duck und Hjort Lake) auf Store Koldewey, einer Insel auf Nordostgrönland, wurden auf ihre fossilen Chironomiden-Vergesellschaftungen untersucht. Im gesamten Holozän konnten 18 ... -

Chitinobelus acifer Fischer 1981, ein Belemnoteuthide (Coleoidea) mit Epirostrum
(Neues Jahrbuch für Geologie und Paläontologie, 1983)The "unusual belemnite" Chitinobelus acifer FISCHER with an "almost purely organic, pinlike epirostrum" and a "calcitic primary rostrum" (FISCHER 1981: 142) is attributed to the order Belemnoteuthida STOLLEY 1919. ... -
Clockwise hysteresis of diatoms in response to nutrient dynamics during eutrophication and recovery
(Limnology and Oceanography, 2022-07-28)Many lake ecosystems that have been severely disturbed by eutrophication, have also experienced large human efforts to restore “natural” conditions. However, the trajectories and the extent of recovery of these lake ... -

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 ... -

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 ... -

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
(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 ... -
