Botanical affinity of the taxa encountered in the Maywood Formation

Michal Zaton, Hu Mingxi, Mercedes Di Pasquo & Paul Myrow
This dataset lists the species of palynomorphs occurring in the Middle Devonian (Givetian) deposits of the Maywood Formation of Cottonwood Canyon, Wyoming, USA. The palynological investigation was carried out in order to decipher the age and paleoenvironment of the microconchid tubeworms (Tentaculita) which were described from the deposits of the Maywood Formation. The retrieved data suggest a likely brackish water origin for the deposits studied, although temporary fully freshwater conditions cannot be ruled out. Indeed,...

The role of bracket fungi in creating alpha diversity of invertebrates in the Białowieża National Park, Poland

Anna K. Gdula, Dariusz J. Gwiazdowicz, Szymon Konwerski, Izabella Olejniczak, Tomasz Rutkowski, Piotr Skubała & Bogna Zawieja
Bracket fungi are seen mainly as the cause of economic losses in forestry and their role as creators of biodiversity is relatively poorly understood. The effect of this group of fungi on the modification of biodiversity of invertebrates (spiders – Aranae, Opiliones – Opiliones, pseudoscorpions – Pseudoscorpionida, two groups of mites – Mesostigmata, and Oribatida, springtails – Collembola, and insects – Insecta) was investigated by analyzing 100 fruiting bodies of 10 species of bracket fungi...

Kristin Ludewig, Yves P. Klinger, Tobias W. Donath, Lukas Bärmann, Carsten Eichberg, Jacob Gadegaad Thomsen, Eugen Görzen, Wiebke Hansen, Eliza M. Hasselquist, Thierry Helminger, Frida Kaiskog, Emma Karlsson, Torsten Kirchner, Carola Knudsen, Nikola Lenzewski, Sigrid Lindmo, Per Milberg, Daniel Pruchniewicz, Elisabeth Richter, Tobias M. Sandner, Judith M. Sarneel, Ralf Schmiede, Simone Schneider, Kathrin Schwarz, Åsa Tjäder … & Rolf Lutz Eckstein
Plant phenology, i. e. the timing of life cycle events, is related to individual fitness and species distribution ranges. Among the environmental factors, phenology is mostly driven by temperature and day length. Rapid adaptation of their phenology may also be important for the success of invasive plant species. Our main aim was to understand how the performance, timing, and temperature dependence of the phenology of the invasive legume Lupinus polyphyllus varies with latitude. L. polyphyllus...

Data from: Tuberculosis-like respiratory infection in 245-million-year-old marine reptile suggested by bone pathologies

Dawid Surmik, Tomasz Szczygielski, Katarzyna Janiszewska & Bruce M. Rothschild
An absence of archaeological and palaeontological evidence of pneumonia in the remote past contrasts with its recognition in the more recent archaeologic record. We document an apparent infection-mediated periosteal reaction affecting the dorsal ribs in a Middle Triassic eosauropterygian historically referred to as ‘Proneusticosaurus’ silesiacus. High-resolution X-ray microtomography (XMT) and histological studies of the pathologically-altered ribs revealed the presence of a continuous solid periosteal reaction with multiple superficial blebs (protrusions) on the visceral surfaces of...

Dataset from the analysis of the expression of oxidative stress-related genes and the activity of their molecular counterparts in bacterial cells treated with metallic nanoparticles

Oliwia Metryka, Daniel Wasilkowski & Agnieszka Mrozik
This dataset contains raw data from the analyses published in the article entitled “Evaluation of the effects of Ag, Cu, ZnO and TiO2 nanoparticles on the expression level of oxidative stress-related genes and the activity of antioxidant enzymes in Escherichia coli, Bacillus cereus and Staphylococcus epidermidis” in International Journal of Molecular Sciences 23 (9):4966 (https://doi.org/10.3390/ijms23094966). The included data consists of results collected for gene expression studies using RT-qPCR reaction for selected bacterial genes of Escherichia...

Raw data from microCT tomography of Ausichicrinites zelenskyyi

Mariusz Salamon, Sreepat Jain, Tomasz Brachaniec, Piotr Duda, Bartosz Płachno & Przemyslaw Gorzelak
Fossil comatulids, referred to as feather stars, are mostly known from highly disarticulated specimens. A single isolated element (centrodorsal) has been the basis for taxonomic description of a vast majority of fossil comatulids. Here, we report a nearly complete, and thus extremely rare, comatulid from the Upper Jurassic (Tithonian) of the Blue Nile Basin in central western Ethiopia that provides a unique insight into the morphology of comatulid arms and cirri. It is assigned to...

Data from: Trends in shell fragmentation as evidence of mid- Paleozoic changes in marine predation

Przemysław Gorzelak, Mariusz A. Salamon, Robert Niedźwiedzki, Dawid Trzęsiok & Tomasz K. Baumiller
Recent observations indicate that shell fragmentation can be a useful tool in assessing crushing predation in marine communities. However, criteria for recognizing shell breakage caused by durophagous predators versus physical factors are still not well established. Here, we provide data from tumbling and aquarium experiments to argue that physical and biotic processes lead to different patterns of shell damage, specifically that angular shell fragments are good indicators of durophagous predation. Using such angular shell fragments...

Data from: The Lilliput effect in crinoids at the end of the Oceanic Anoxic Event 2: a case study from Poland

Krzysztof Roman Brom, Mariusz Andrzej Salamon, Bruno Ferré, Tomasz Brachaniec & Krzysztof Szopa
The Cretaceous period (145-66 Ma) consists of several Oceanic Anoxic Events (120-80 Ma), stimulated by global greenhouse effects. The Oceanic Anoxic Event 2 (OAE2) occurred worldwide from the late Cenomanian to the early-middle Turonian, causing a significant faunal turn-over, mostly in marine biota pushing some species to the brink of extinction. Some organisms also underwent morphological changes, including reduction in size. This anoxic event drove other changes, e.g., habitats or strategy of life. Here, we...

Data from: Temporal dynamics of encrusting communities during the Late Devonian: a case study from the Central Devonian Field, Russia

Michal Zaton, Tomasz Borszcz & Michal Rakocinski
In this study we focused on the dynamics of encrusting assemblages preserved on brachiopod hosts collected from upper Frasnian and lower Famennian deposits of the Central Devonian Field, Russia. Because the encrusted brachiopods come from deposits bracketing the Frasnian/Famennian (F/F) boundary, the results also shed some light on ecological differences in encrusting communities before and after the Frasnian–Famennian (F-F) event. To explore the diversity dynamics of encrusting assemblages, we analyzed more than 1300 brachiopod valves...

Measurements of bite traces on bones

Grzegorz Sadlok
Carnivores make traces on bones with their teeth when feeding. A true predatory bite trace (predichnia) forms when a predator catches and kills its prey or attempts to do so. Both predators and scavengers may leave their non-predatory feeding traces during postmortem food processing. Despite the interpretative uncertainties as to the ethology such ichnofossils may represent, the bite traces have been traditionally classified as predichnia – traces of predation. Previously, there was no alternative ethological...

Single and mixed arbuscular mycorrhizal fungal species inocula have a different effect on the growth and oxidative stress defense in Lolium perenne exposed to phenol and polynuclear aromatic hydrocarbons

Monika Malicka, Franco Magurno, Posta Katalin, Damian Chmura & Zofia Piotrowska-Seget
Arbuscular mycorrhizal fungi (AMF) are ubiquitous mutualistic plant symbionts which promote plant growth and protect them from abiotic stresses. Studies on AMF-assisted phytoremediation have shown that AMF can increase plant tolerance to the presence of hydrocarbon contaminants by improving plant nutrition status and mitigating oxidative stress. This work aimed to evaluate the impact of single-species or mixed-species AMF inocula, obtained from the contaminated environment (Funneliformis caledonium, Diversispora varaderana, Claroideoglomus walkeri), on a growth, oxidative stress...

Tracking the ancestry of known and ‘ghost’ homeologous subgenomes in model grass Brachypodium polyploids

Rubén Sancho, Luis Ángel Inda, Antonio Díaz-Pérez, David L Des Marais, Sean Gordon, John Vogel, Joanna Lusinska, Robert Hasterok, Bruno Contreras-Moreira & Pilar Catalán
Unraveling the evolution of plant polyploids is a challenge when their diploid progenitor species are extinct or unknown or when genome sequences of known progenitors are unavailable. Existing subgenome identification methods cannot adequately infer the homeologous genomes that are present in the allopolyploids if they do not take into account the potential existence of unknown progenitors. We addressed this challenge in the widely distributed dysploid grass genus Brachypodium, which is a model genus for temperate...
