Dragonflies and damselflies are among the earliest flying insects with extant
representatives. However, unraveling details of their long evolutionary history, such as egg …

Cycads are ancient seed plants (gymnosperms) that emerged by the early Permian.
Although they were common understory flora and food for dinosaurs in the Mesozoic, their …

The taxonomy of the soft-shell turtle Rafetus bohemicus (Liebus, 1930), family Trionychidae,
subfamily Trionychinae, is revised based on new and previously mentioned material …

Arid central Asia plays an important role in global climate dynamics, but large uncertainties
remain in our understanding of the region's hydroclimate variability during the Late …

In the low-nutrient, redox-stratified Lake Medard (Czechia), reductive Fe (III) dissolution
outpaces sulfide generation from microbial sulfate reduction (MSR) and ferruginous …

Spectral analysis is a key tool for identifying periodic patterns in sedimentary sequences,
including astronomically related orbital signals. While most spectral analysis methods …

The work investigates the extensive freshwater lacustrine deposits of the Most Formation,
which formed in the period between 17.7 Ma and ca. 15.9 Ma, in order to describe climate …

Petrophysical (gamma-ray spectrometry, magnetic susceptibility) and geochemical (X-ray
fluorescence spectrometry and inorganic carbon isotope geochemistry) methods are used …

Weathering indices quantify the release of mobile elements from source units of soils and
sediments. They have been employed in geosciences for more than three decades, but their …

The extraction of palaeoenvironmental (palaeoclimatic) signals from the chemical
composition of siliciclastic sediments is valuable for the reconstruction of past environments …
