The xylem of Metasequoia glyptostroboides Hu et Cheng is characterized by very low density (average specific gravity = 0.27) and tracheids with relatively large dimensions (length and diameter). The microfibril angle in the S2 layer of tracheid walls is large, even in outer rings, suggesting a cambial response to compressive rather than tensile stresses. In some cases, this compressive stress i...

The Versilia plain (NW Italy) experiences forms of tourism that are mainly limited to the beach area and concentrated in summer season. is rich cultural natural heritage, not yet adequately enhanced. presence four local archaeological museums a park offers great opportunity favour feasible environmental tourism. aim this study use holistic methodology improve different type area.

Decisions on settlement location in the face of climate change and coastal inundation may have resulted in success, survival or even catastrophic failure for early settlers in many parts of the world. In this study we investigate various questions related to how individuals respond to a palaeoenvironmental simulation, on an interactive tabletop device where participants have the opportunity to ...

Abstract In this study, we combined the geochemical characteristics based on Rock-Eval pyrolysis and gas chromatography – mass spectrometry (GC–MS) results with facies analysis. These surveys were conducted within grey to black claystones/mudstones intervals of Podil’tsi Kokhanivka formations, related Pliensbachian Toarcian–Bathonian ages, respectively. The revealed that Formation contains mixe...

The fossil biota of the upper Valanginian–lower Hauterivian sediment hosted vent (SHV) environment Zeng?várkony comprises 39 species, 55 genera and higher taxa representing seven phyla. Thirteen these are reported from Zeng?rvárkony as new species or subgenera/genera, this high endemicity is linked to a unique palaeoenvironment. palaeoenvironment developed in an outer shelf epicontinental setti...
