Taxonomy and diversity of slit‐band gastropods (Order Pleurotomariida) and some slit bearing Caenogastropoda from the Pennsylvanian of the USA
(
- Papers in Palaeontology
, 2022-04-11)
Pleurotomariida have the longest fossil record among living gastropods and are diverse and abundant in the middle and upper Palaeozoic. Its traditional classification is based on adult shell characters. The early shell ...
Sedimentary DNA identifies modern and past macrophyte diversity and its environmental drivers in high‐latitude and high‐elevation lakes in Siberia and China
(

, 2022-03-16)
Arctic and alpine aquatic ecosystems are changing rapidly under recent global warming, threatening water resources by diminishing trophic status and changing biotic composition. Macrophytes play a key role in the ecology ...
Mesocrystalline Architecture in Hyaline Foraminifer Shells Indicates a Non‐Classical Crystallisation Pathway
(
- Geochemistry, Geophysics, Geosystems
, 2022-06-15)
Calcareous foraminifer shells (tests) represent one of the most important archives for paleoenvironmental and paleoclimatic reconstruction. To develop a mechanistic understanding of the relationship between environmental ...
Late Quaternary paleoenvironmental reconstructions from sediments of Lake Emanda (Verkhoyansk Mountains, East Siberia)
(
- Journal of Quaternary Science
, 2022-05-06)
Continuous pollen and chironomid records from Lake Emanda (65°17′N, 135°45′E) provide new insights into the Late Quaternary environmental history of the Yana Highlands (Yakutia). Larch forest with shrubs (alders, pines, ...
Always ready? Primary production of Arctic phytoplankton at the end of the polar night
(
- Limnology and Oceanography Letters
, 2021-11-11)
The end of the polar night with the concurrent onset of photosynthetic biomass production ultimately leads to the spring bloom, which represents the most important event of primary production for the Arctic marine ecosystem. ...
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 ...
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 ...
Palaeoecological signals for Mesolithic land use in a Central European landscape?
(
- Journal of Quaternary Science
, 2022-05-12)
During the Early Holocene, climate was the major factor causing fires, but whether during the Mesolithic (~11.5–7.4 cal ka BP) people co‐shaped their environment by means of fire remains of debate. Few studies have tackled ...
Flexible habitat choice of pelagic bacteria increases system stability and energy flow through the microbial loop
(
- Limnology and Oceanography
, 2022-04-19)
Pelagic bacteria can be classified into free‐living and particle‐attached life modes, which either dwell in the water column or attach to suspended particles. Bacteria with a generalist life style, however, can actively ...
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 ...
