After 100 years: a detailed view of an eumalacostracan crustacean from the Upper Jurassic Solnhofen Lagerstätte with raptorial appendages unique to Euarthropoda
; ; Schweigert, Günter; ; (Lethaia, 2020)
The Solnhofen Konservat-Lagerstätte yields a great number of remarkably preserved fossils of eumalacostracan crustaceans that help us understand the early radiation of several groups with modern representatives. One fossil ... -
Alectorioid Morphologies in Paleogene Lichens: New Evidence and Re-Evaluation of the Fossil Alectoria succini Mägdefrau.
(PloS one, 2015)One of the most important issues in molecular dating studies concerns the incorporation of reliable fossil taxa into the phylogenies reconstructed from DNA sequence variation in extant taxa. Lichens are symbiotic associations ... -
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. ... -
An ancient process in a modern mollusc: early development of the shell in Lymnaea stagnalis
(BMC Developmental Biology, 2013)Background The morphological variety displayed by the molluscan shell underlies much of the evolutionary success of this phylum. However, the broad diversity of shell forms, sizes, ornamentations and functions contrasts ... -
An Antarctic molluscan biomineralisation tool-kit
(Scientific Reports, 2016)The Antarctic clam Laternula elliptica lives almost permanently below 0 °C and therefore is a valuable and tractable model to study the mechanisms of biomineralisation in cold water. The present study employed a ... -
An early Eocene fossil from the British London Clay elucidates the evolutionary history of the enigmatic Archaeotrogonidae (Aves, Strisores)
(Papers in Palaeontology, 2021-07-18)
Archaeotrogons have long been known from late Eocene and Oligocene localities in France, where limb bones are abundantly represented. The phylogenetic affinities of these birds, however, have remained elusive. Although ... -
Ancylotherium pentelicum (Mammalia, Chalicotheriidae) from the late Miocene of Kerassia (Greece) and remarks on its intraspecific variability
; ; ; ; ; (Palaeobiodiversity and Palaeoenvironments, 2021-07-13)
The first detailed description of Ancylotherium pentelicum (Gaudry and Lartet, 1856) from the late Miocene (Turolian) of Kerassia (Greece) is provided based on three metapodial elements. Potential intraspecific variability ... -
Ankylosaur Remains from the Early Cretaceous (Valanginian) of Northwestern Germany
Sachs, Sven; (PLOS ONE, 2013-04-03)
A fragmentary cervico-pectoral lateral spine and partial humerus of an ankylosaur from the Early Cretaceous (early Valanginian) of Gronau in Westfalen, northwestern Germany, are described. The spine shows closest ... -
Aquatic and terrestrial proxy evidence for Middle Pleistocene palaeolake and lake‐shore development at two Lower Palaeolithic sites of Schöningen, Germany
; Tucci, Mario; Urban, Brigitte; Pilgrim, Julien; ; Soulié‐Märsche, Ingeborg; (Boreas, 2021-05-06)
The archaeological sites in the open‐cast mine of Schöningen, Germany, represent outstanding archives for understanding Middle Pleistocene interglacial–glacial transitions and human adaption. Aquatic microfossil and pollen ... -
Archaea in Symbioses
(Archaea, 2012)During the last few years, the analysis of microbial diversity in various habitats greatly increased our knowledge on the kingdom Archaea. At the same time, we became aware of the multiple ways in which Archaea may interact ... -
ArchbotLit—the archaeobotanical literature database: an update of the search engine for literature on archaeological remains of cultivated plants since 1981
; ; ; ; (Vegetation History and Archaeobotany, 2020-09-13)
The online Archaeobotanical Literature Database (ArchbotLit) is an important tool for getting targeted access to archaeobotanical publications. It offers the opportunity for archaeobotanists, archaeologists, freelancers, ... -
As above, so below? Effects of fungicides on microbial organic matter decomposition are stronger in the hyporheic than in the benthic zone
; ; ; ; ; ; ; (Limnology and Oceanography, 2021-11-16)
Microbial organic matter decomposition is a critical ecosystem function, which can be negatively affected by chemicals. Although the majority of organic matter is stored in sediments, the impact of chemicals has exclusively ... -
Bacterial and archaeal lipids trace chemo(auto)trophy along the redoxcline in Vancouver Island fjords
; ; ; ; (Geobiology, 2021-05-07)
Abstract Marine oxygen minimum zones play a crucial role in the global oceanic carbon, nitrogen, and sulfur cycles as they harbor microbial communities that are adapted to the water column chemistry and redox zonation, and ... -
Beiträge zur Paläontologie

Reihe A, Geologie und Paläontologie; Band 32)Der Band enthält neben eines Beitrags zum Lebenswerk des Paläontologen Walter Georg Kühne aus Anlass seines 70. Geburtstags eine Reihe von Aufsätzen zu verschiedenen paläontologischen Themen von Angehörigen der ... -
Beiträge zur Systematik von phragmokontragenden Coleoiden aus dem Untertithonium (Malm zeta, "Solnhofener Plattenkalk") von Solnhofen und Eichstätt (Bayern)

Benthic Foraminifera of the Agulhas Bank coastal shelf in the vicinity of Plettenberg Bay, South Africa: a reconnaissance survey
; (Geo-Marine Letters, 2021-04-16)
The study area is located on the inner Agulhas Bank around Plettenberg Bay, southern Cape Province, South Africa (Fig. 1). The Agulhas Bank is a transitional environment between the cold-temperate Benguela Current regime ... -

Biofilm pads—an easy method to manufacture artificial biofilms embedded in an alginate polymer matrix
; ; ; (Limnology and Oceanography: Methods, 2019)
Periphytic biofilms are the major resource for many herbivorous invertebrates in both marine and freshwater benthos. They are of crucial importance for benthic food webs, substrate stability, and biogeochemical processes ...
