Abstract Visual conditions around Palaeolithic sites determine how the landscape was perceived by prehistoric hunter-gatherers. By placing site in different landscapes, visual foci were encoded locational characteristics of places. For Early Ahmarian Levant, it can be shown that differ significantly with combination large ungulate prey exploited at respective location. A Higuchi viewshed approa...

Irano-Turanian floristic region in Turkey appears to be the center of origin Crepis foetida subsp. rhoeadiflolia (Asteraceae). In this study, karyotype and flow cytometric analyses six populations C. were performed. The cytogenetic characteristics using multivariate (cluster analysis, principal components analysis) evaluated a cytogeographic context. Two main groups are found based on among dis...

In this paper, the new taxa Lepidium ferganense (Brassicaceae) was recorded for the flora of Iran for the first time. This taxon belongs to Irano-Turanian region. It was compared with the closest taxa in the present study. In addition, a morphological description, several Illustrations, and a distribution map were presented.

In this research, vascular plants of Bamu National Park (48000 ha.) situated in Fars province were studied. Analyses of all collected plants (450 species) showed that on account of climatic conditions, 94% of them were flowering in spring, also hemicryptophytes and therophytes possess abundant growth form with 39.6% and 23.5%, respectively. Phytogeographically, Irano-Turanian  elements comprise...

This study assessed the floristic composition, biological spectrum, and phytogeographical elements of Bin Dara western boundary Pakistan. The flora consisted 140 plant species belonging to 47 families. most dominant family was Poaceae (with 14 species), followed by Asteraceae (11 species). spectrum showed therophytes (71 species, 50.71%) as life form class, mega-phanerophytes (27 19.28%), nano-...
