flower morphology of ten fritillaria species of subgenera theresia and fritillaria growing wild in iran is studied using seventy morphological characters. qualitative and quantitative datasets separated taxa into subgenera, sectional and groups. three enigmatic species f. caucasica, f. zagrica (endemic to zagros mountains) and f. pinardii (recently reported from zagros mountains) appeared as cl...

Flower morphology of 10 Fritillaria species of subgenera Theresia and Fritillaria growing wild in Iran is studied using seventy morphological characters. Qualitative and quantitative datasets separated taxa into subgenera, sectional and groups. Three enigmatic species F. caucasica, F. zagrica (endemic to Zagros Mountains) and F. pinardii (recently reported from Zagros Mountains) appeared as clo...

there has been more than four decades since frank hole and kent flannery conducted a field expedition in central zagros mountains located in western iran, in 1963. from then onward, numerous discoveries and field projects have been done in this region. some of these findings may contradict the report of the original survey. although the goal of this article by no means, is to criticize the 1967...

spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. this research was investigated in the chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, central zagros forest, and southwest iranian state. in this study 53 hectare of the study area was selected and perfect inventory.  information includes the position and kind...

according to zooarchaeological evidence, central zagros as a center of domestication experienced independently the first step of livestock domestications. it seems that capra hircus have been domesticated about 10,500 b.c in central zagros and since then, has played a key role in the food economy of this region. outstanding development of genetics shed new lights on the origins of goat and dome...

Quantified balanced and restored crustal cross-sections across the NW Zagros Mountains are presented in this work integrating geological and geophysical local and global datasets. The balanced crustal cross-section reproduces the surficial folding and thrusting of the thick cover succession, including the near top of the Sarvak Formation (∼ 90 Ma) that forms the top of the restored crustal cros...

1. introduction mountains are the main sources of turbulence and change in the shape of atmospheric flows, and they can cause airflow upward as well as clouds formation and rain through productive mechanisms such as upslope condensation and convection. they also have an important effect on regional and world precipitation turbulence (banta, 1990; barros & lettenmaier, 1994), and can cause sever...

Forests remain an important resource in Iran, as most of the livelihood activities local communities, especially semi-arid environment Zagros forests, are dependent on forest resources. The aim this study was to identify type and extent dependency. Semi-structured interviews questionnaires were used collect data from 170 households Central Zagros. Results show that using firewood for fuel non-f...
