Plecopteran species (Leuctridae) were collected from the Qinling Mountains in southern Shaanxi Province, China. This mountain range is home to nine species of Leuctridae belonging to two genera, and the species identified in this work include one new species and three new records for the Qinling Mountains, all belonging to the genus Rhopalopsole. The new species is named R. tricuspis Qian and D...

According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent subdivisions of the tundra biome. We seek an ecologically natural resolution to this long-standing and far-reaching problem. We studied broad-scale patterns in climate and vegetati...

massive than all human structures combined and are sculpted in greater detail than a Baroque palace. The world’s tallest pinnacle—Mount Everest in the Himalayas— reaches 8,848 meters, or about 15 times higher than anything people have ever built. Not surprisingly, such spectacular topography has evoked awe and inspired artists and adventurers throughout human existence. Recent research has led ...

Javoří hory Mountains is a part of Intra Sudetic Basin that belongs to the Permian-Carboniferous section of the Bohemian Massif, whose geological evolution was strongly influenced by volcanic activity. In the Pleistocene epoch cryogenic processes modeled the mountains significantly (frost cliffs, gelifluction streams), which resulted, in connection to the slope orientations, in substantial moun...

The paper illustrates some results of research carried out to assess factors triggering debris flows which involve the pyroclastic overburdens covering carbonate mountains around Vesuvius. The aims of the research were to reconstruct a relationship between rainfall and debris flow occurrence and to highlight empirical hydrological thresholds through rainfall pattern analysis. The research was a...

Homoleptic metal-sugar complexes were obtained in the form of MnIIand FeII-diacetoneglucose derivatives. The protolysis of [Mn3Mes6] and [Fe2Mes4] (Mes ) 2,4,6-Me3C6H2) with DAGH (1,2:5,6-di-O-isopropylideneR-D-glucofuranose, diacetoneglucose) led to [M(DAG)2] [M ) Mn (1), Fe (2)]. Although monomeric in solution, they showed a different degree of aggregation in the solid state, iron being monom...

Carboniferous strata in the Alborz mountains consist of calcareous rich fossils the main part of which is composed of rugose corals. There have been few studies carried out on corals so far. In this paper, a new subfamily, genus and eight new species of rugose corals from Mobarak limestones in the central Alborz mountains are introduced
