Testing the use of the silica deposition fluorescent probe PDMPO to estimate in situ growth rates of diatoms
(Limnology and Oceanography: Methods, 2022-08-12)The fluorophore [2‐(4‐pyridyl)‐5{[4‐dimethylaminoethyl‐aminocarbamoyl‐methoxy]phenyl}oxazole], in short PDMPO, is incorporated in newly polymerized silica in diatom frustules and thereby provides a tool to estimate Si ... -
Testing the usefulness of optical data for zooplankton long‐term monitoring: Taxonomic composition, abundance, biomass, and size spectra from ZooScan image analysis
(Limnology and Oceanography: Methods, 2022-05-28)The pelagic ecosystem of the Arctic Ocean is threatened by severe changes such as the reduction in sea‐ice coverage and increased inflow of warmer Atlantic water. The latter is already altering the zooplankton community, ... -

The bipolar bivalve Oxytoma (Palmoxytoma) cygnipes (Young & Bird, 1822) in the Upper Pliensbachian of Germany
(Paläontologische Zeitschrift, 2011)The morphologically conspicuous bivalve Oxytoma (Palmoxytoma) cygnipes (Young & Bird, 1822), known for its palaeogeographically bipolar distribution, from a limestone bed in the boundary “Belemniten–Schichten”/Amaltheenton ... -
The detection of bacterial exometabolites in marine dissolved organic matter through ultrahigh‐resolution mass spectrometry
(Limnology and Oceanography: Methods, 2022-05-05)Bacteria play a key role in sustaining the chemodiversity of marine dissolved organic matter (DOM), yet there is limited direct evidence of a major contribution of bacterial exometabolites to the DOM pool. This study tests ... -
The early Cenomanian crippsi Event at Lüneburg (Germany): palaeontological and stratigraphical significance of a widespread Late Cretaceous bioevent
(Palaeobiodiversity and Palaeoenvironments, 2021-01-07)The early Cenomanian crippsi Event comprises a 1–3-m-thick interval characterised by mass occurrences of the early Cenomanian inoceramid Gnesioceramus crippsi, identified in the uppermost Sharpeiceras schlueteri Subzone ... -
The evolution of thecideide microstructures and textures: traced from Triassic to Holocene
(Lethaia, 2021-04-02)Thecideide brachiopods are an anomalous group of invertebrates. In this study, we discuss the evolution of thecideide brachiopods from the Triassic to the Holocene and base our results and conclusions on microstructure and ... -
The first belemnite of boreal ancestry from the Early Cretaceous (Valanginian) of the western Tethys: implications for belemnite ecology
(Papers in Palaeontology, 2022-07-17)The first occurrence of the belemnite species Liobelus acrei (formerly Acroteuthis acrei) is reported from the Lower Cretaceous (Valanginian) of the Vocontian Basin (VB; south‐east France). This first record of the genus ... -
The first report of an ‘evergreen Castanopsis type’ wood (Fagaceae) for the Late Miocene–Early Pliocene of Europe (Bulgaria, Blagoevgrad Graben)
(Geological Journal, 2020)In the present article, the establishment of the species Castanopsis: C. bulgarica Mantzouka, Ivanov, and Bozukov is proposed after the study of a new fagaceous fossil wood stem discovered in 2016 from a new Late Miocene ... -

(Palaeobiodiversity and Palaeoenvironments, 2020-11-02)A Late Devonian to (?)Early Mississippian section at Hushoot Shiveetiin gol in the Baruunhuurai Terrane of the Central Asian Orogenic Belt (CAOB) exposes large parts of cyclic Famennian shallow-water siliciclastic shelf ... -
The Impact of Typhoon “Mangkhut” on Surface Water Nutrient and Chlorophyll Inventories of the South China Sea in September 2018
(Journal of Geophysical Research: Biogeosciences, 2021-12-14)The influence of the exceptionally strong typhoon Mangkhut on the availability of nutrients and changes in primary production were studied in the northern South China Sea in September 2018. A tight station grid was sampled ... -
The Influence of Plankton Community Structure on Sinking Velocity and Remineralization Rate of Marine Aggregates
(Global Biogeochemical Cycles, 2019)Gravitational sinking of photosynthetically fixed particulate organic carbon (POC) constitutes a key component of the biological carbon pump. The fraction of POC leaving the surface ocean depends on POC sinking velocity ... -
