“Bestowed by the Austrian Emperors”. Religious Denomination and Dynastic Loyalty in the Romanian Society of Transylvania in the Eighteenth Century

Greta Monica Miron
In this study I am focussing on the self-image that eighteenth-century Habsburg sovereigns, especially Maria Theresa and Joseph II, disseminated among the Romanian communities in Transylvania, via the Greek-Catholic Church, in order to strengthen the loyalty of their subjects. I also examine the means of communication with the Romanian subjects and the latter’s reaction to the dynastic identities circulated throughout the principality. My intention is to capture the changes and innovations that occurred in Romanian...

Data from: Influential neighbours: seeds of dominant species affect the germination of common grassland species

Annamária Fenesi, Kinga Kelemen, Dorottya Sándor & Eszter Ruprecht
Questions Germination is the prerequisite of successful establishment in plant communities and is influenced by many factors. Therefore, seeds are under strong selective pressure to sense and integrate information about their environment and modulate germination based on them. In this study, we focus on interspecific seed-seed interactions under optimal and sub-optimal conditions to test three hypotheses: (H1) Dominant species’ seeds and emerging seedlings are most likely to be recognized and insert significant effect on the...

Environmental drivers of Sphagnum growth in peatlands across the Holarctic region

Payne
The relative importance of global versus local environmental factors for growth and thus carbon uptake of the bryophyte genus Sphagnum – the main peat-former and ecosystem engineer in northern peatlands – remains unclear. 2) We measured length growth and net primary production (NPP) of two abundant Sphagnum species across 99 Holarctic peatlands. We tested the importance of previously proposed abiotic and biotic drivers for peatland carbon uptake (climate, N deposition, water table depth, and vascular...

Down feather morphology reflects adaptation to habitat and thermal conditions across the avian phylogeny

Peter Laszlo Pap, Gergely Osváth, Timea Daubner, Andreas Nord & Orsolya Vincze
Down feathers are the first feather types that appear in both the phylogenetic and the ontogenetic history of birds. Although it is widely acknowledged that the primary function of downy elements is insulation, little is known about the interspecific variability in the structural morphology of these feathers, and the environmental factors that have influenced their evolution. Here, we collected samples of down and afterfeathers from 156 bird species and measured key morphological characters that define...

Ions release from hydroxyapatite and substituted hydroxyapatites in different immersion liquids: In vitro experiments and theoretical modelling study

The multi-substituted hydroxyapatites (ms-HAPs) are currently gaining more consideration due to their multifunctional properties and biomimetic structure, owning thus an enhanced biological potential in orthopedic and dental applications. In this study, nano hydroxyapatite (HAP) substituted with multiple cations (Sr2+, Mg2+ and Zn2+) for Ca2+ and anion (SiO44-) for PO43- and OH-, specifically HAPc-5%Sr and HAPc-10%Sr (where HAPc is HAP-1.5%Mg-0.2%Zn-0.2%Si), both lyophilized noncalcined and lyophilized calcined, were evaluated for their in vitro ions release. These nanomaterials...
