Environmental (topography, climate) features have an important influence on plant diversity and richness of Iran. Topography is from –28m which is close to Caspian Sea to 5678m which is located on the Alborz Mountain. Two mountains (Alborz and Zagrosss) prevent moist air moving to the centre of Iran. On the basis of environmental factors, four ecological zones with specific plant richness from ...

Medicinal plants are indicators of indigenous knowledge in the context of political volatility and sociocultural and ecological change in the Pamir Mountains of Afghanistan and Tajikistan. Medicinal plants are the primary health care option in this region of Central Asia. The main objective of this paper is to demonstrate that medicinal plants contribute to health security and sovereignty in a ...

Mountain gorillas, the largest extant primates, subsist almost entirely on plant matter. Moreover, their diet includes a substantial amount of structural material, such as bark and stems, which other primates tend to avoid. Accordingly, the robust masticatory apparatus of gorillas may be adaptive to this presumably tough diet; however, quantitative information on this subject is lacking. In thi...

Recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. Little is known about thevegetation composition of Boralan Mountain region located in North West of Iran in theborder of Turkey and Azerbaijan with the altitude range of 800-2000m. The aim of thisstudy therefore was to investigate the floristic composition qua...

Plants growing in high-mountain environments may share common morphological features through convergent evolution resulting from an adaptative response to similar ecological conditions. The Carex flava species complex (sect. Ceratocystis, Cyperaceae) includes four dwarf morphotypes from Circum-Mediterranean mountains whose taxonomic status has remained obscure due to their apparent morphologica...

The biome concept is used to classify vegetation into distinct groups. This concept integrates the relationship of plants and animals with their distributions. North America is comprised of 11 biomes (arctic tundra, desert, broad sclerophyll, pinyon-juniper, temperate grasslands, northern coniferous forest, moist temperate coniferous forest, temperate deciduous forest, mountain complex, subtrop...

Understanding diversity patterns along environmental gradients and their underlying mechanisms is a major topic in current biodiversity research. In this study, we investigate for the first time elevational patterns of vascular plant species richness and endemism on a long-isolated continental island (Crete) that has experienced extensive post-isolation mountain uplift. We used all available da...
