Here we studied the adaptation of plant communities to environment in the alpine belt of the Catalan Pyrenees through comparative analysis of plant traits. The starting point consisted of about 800 phytocoenological relevés from the Banc de Dades de Biodiversitat de Catalunya, which corresponded to 47 communities (associations and subassociations) and included 683 taxa. Eleven attributes were e...

Alpine floras (plants in the vegetation belts above climatic treelines) experience cold climates, particularly temperate mountains during winter, but they are generally species-rich. Yet, biogeographers have not determined whether these represent evolutionarily independent convergent assemblages drawn from their regional floras, or originated particular clades pre-adapted to harsh conditions. H...

Alpine vegetation is scarce in central Mexico (≈150 km2) and occurs on the 11 highest peaks of Trans-Mexican Volcanic Belt (TMVB). Timberline at (3700) 3900 m, 4750 m vascular plants cease to exist. The alpine flora comprises 237 species from 46 families 130 genera. Asteraceae (44), Poaceae (42), Caryophyllaceae (21) possess 45% species; none remaining have more than 10 species. Four are strict...

A 20-year capture-recapture study of alpine grasshoppers spanned three distinct sequences of abundance, featuring in turn dis-equilibrium, equilibrium and secondary cyclic equilibrium. This succession of population patterns in the most abundant species, Paprides nitidus, retained high stability between generations. It arose via superimposed life-cycle pathways and adaptive responses between gra...

The paper presents the analysis of genus Thymus flora South-East North Caucasus. Revealed total species, compiled an aspect , and conducted analysis's bioecological, geographical composition. In investigated territory, we have registered eight thymus distributed mainly in xerophilic types vegetation: steppe, friganoid, alpine, meadow-steppe, meadow societies.

The highest parts of the European mountain massifs are covered by subalpine and alpine vegetation, with rich flora containing many relic woody plants adapted to cold temperatures relatively short vegetation periods. In Ukrainian Carpathians, only several form environmental conditions suitable for high plants. aim study was detection centre biodiversity in East Carpathians Ukraine. We expected l...

The genus Silene, with more than 100 species in Iran is an important genus of Iranian flora. According to available data on the northwestern parts of Iran, including three provinces of Ardabil, East and West Azarbaijan are considered as a major diversity center of perennial species of the genus Silene in Iran. In the course of a revision of Silene in this area, some interesting specimens were c...
