Morphological Characterization of Fossil L. Seeds from the Gelasian of Italy by Seed Image Analysis.

The discovery of well-preserved fossil L. seeds from the Gelasian stage in Italy has provided a unique opportunity to investigate the systematics of fossilized species. Through seed image analyses and elliptical Fourier transforms of fossil seeds from the sites Buronzo-Gifflenga and Castelletto Cervo II, we pointed out a strong relationship to the group of extant Eurasian species.

Archosauriform footprints in the Lower Triassic of Western Alps and their role in understanding the effects of the Permian-Triassic hyperthermal.

The most accepted killing model for the Permian-Triassic mass extinction (PTME) postulates that massive volcanic eruption (i.e., the Siberian Traps Large Igneous Province) led to geologically rapid global warming, acid rain and ocean anoxia.

Ecology, threats and conservation status of Carex buekii (Cyperaceae) in Central Europe.

Carex buekii is a tall sedge, forming large stands in wetlands, particularly in river floodplains across Central Europe and thus on many sites determining the typical appearance of riverine habitats. Our paper aims at increasing the knowledge on ecology of C. buekii and its role in the wetlands.

Toward an accurate taxonomic interpretation of Carex fossil fruits (Cyperaceae): a case study in section Phacocystis in the Western Palearctic.

Premise Of The Study: Despite growing interest in the systematics and evolution of the hyperdiverse genus Carex, few studies have focused on its evolution using an absolute time framework. This is partly due to the limited knowledge of the fossil record. However, Carex fruits are not rare in certain sediments.
