Globally, around 0.78 billion rural people live in close proximity to forests and have been considered “forest-dwelling” and/or “forest dependent”. Forest dependency has so far mainly studied material terms, while the non-material relationships addressed less frequently. To fill this gap, general objective of study is assess forest-dwelling people’s relationship their community, livestock, fore...

Ludab region, known for its unique landscape comprising a vast fertile plain surrounded by high mountains and covered by loose oak forests, is a part of Boyer-Ahmad County in southern Zagros mountain range (West Iran) with an area of 87,715 km2 located 110 km north-west of the capital city, Yasuj. The aim of this research is to assess floristic elements, life forms, chorology, and en...

Estimating the lateral depth variations of the Earth’s crust from gravity data is a non-linear ill-posed problem. The ill-posedness of the problem is due to the presence of noise in the data, and also the non-uniqueness of the problem. Particle Swarm Optimization (PSO) is a stochastic population-based optimizer, originally inspired by the social behavior of fish schools and bird flocks. PSO is ...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...

Kelussia odoratissima Mozaff. is a species of Apiaceae endemic to the Zagros Mountains in Iran. In present investigation, for first time, polyphenolic compounds and flavonoids its leaves were determined by liquid chromatography-mass spectrometry (LC-MS). As result, p-coumaric acid, ferulic caffeic chlorogenic acetyl phloroglucinol, vanillic m-coumaric 4-methylsiringol as main phenolic compounds...

Landslides are the main secondary effects of earthquakes in mountainous areas. The spatial distribution these landslides is controlled by local seismic ground motion and slope stability. While gravitational instabilities arid semi-arid environments understudied, we document triggered Sarpol Zahab earthquake (November 12, 2017, Mw7.3, Iran/Iraq border), largest event ever recorded Zagros Mountai...

The medicinal use of natural products—compounds that are derived from natural sources such as plants, animals or micro-organisms—precedes recorded human history probably by thousands of years. Palaeoanthropological studies at the cave site of Shanidar, located in the Zagros Mountains of Kurdistan in Iraq, have suggested that more than 60,000 years ago, Neanderthals might have been aware of the ...

Abstract Understanding climate change in the Middle East (ME) is crucial because people’s living environment depends on rain-fed crop systems. It remains unclear whether ME would be affected by Saharan vegetation collapse at end of mid-Holocene (MH). Proxy data suggest a transition from humid to more arid conditions during period 6.5–5 kyr BP. Using set idealized sensitivity experiments with an...

A significant amount of the ongoing shortening between Eurasian and Arabian plates is accommodated within Zagros Fold-Thrust Belt. However, spatial temporal distribution active belt, especially in its NW part, not yet well constrained. We determined depositional ages uplifted river terraces crossing belt along Greater Zab River using luminescence dating. Kinematic modeling fault-related fold wa...
