The Alpine Flora of Colorado

Alpine flora of Hezar mountain (SE Iran)

Iran is a mountainous country. Hezar Mt., is an isolated mountain with the highest peak of 4465 m (above sea level) located in southeast of Iran. This paper aims to provide a general overview of alpine phytodiversity of Hezar Mt. Alpine regions are above timber-line which is dependent on the climate, slopes and human activities. The timberline at Hezar Mt., is varying from 3200 m (North slope) ...

Seasonal changes in an alpine soil bacterial community in the colorado rocky mountains.

The period when the snowpack melts in late spring is a dynamic time for alpine ecosystems. The large winter microbial community begins to turn over rapidly, releasing nutrients to plants. Past studies have shown that the soil microbial community in alpine dry meadows of the Colorado Rocky Mountains changes in biomass, function, broad-level structure, and fungal diversity between winter and earl...

Effects of Seasonal Weather on Breeding Phenology and Reproductive Success of Alpine Ptarmigan in Colorado

Animal populations occurring at high elevations are often assumed to be in peril of extinctions or local extirpations due to elevational-dispersal limitations and thermoregulatory constraints as habitats change and warm. However, long-term monitoring of high-elevation populations is uncommon relative to those occurring at lower elevations, and evidence supporting this assumption is limited. We ...

Flora of Jahanbin Mountain Area: A Contribution to Flora of the Central Zagros Region of Iran
