Pollen analysis of the peat in a small mire on northern slope Alborz Mountains (550 m a.s.l.) Central Caspian forests Iran reveals changes forest and wetland vegetation during last millennium. A forest, principally Alnus Carpinus occurred over almost whole period. Quercus, Ulmus Parrotia were less common, while Fagus, Pterocarya, Acer Diospyros fluctuated as probable result human interference and/or climatic change. Two phases clay deposition can be dated to `Mediaeval Climatic Anomaly' (AD...
Abstract Aim To evaluate the biomization technique for reconstructing past vegetation in Eastern Mediterranean–Black Sea–Caspian‐Corridor using an extensive modern pollen data set and comparing reconstructions to potential observed land cover data. Location The region between 28–48°N 22–62°E. Methods We apply 1,387 samples, representing 1,107 entities, reconstruct distribution of 13 broad categories (biomes). assess results estimates natural from European Vegetation Map Physico‐Geographic...
Unfavourable climatic conditions force Iranian beekeepers to translocate over large distances in the course of year. However, irrespective main place production, honey is always labeled with name beekeepers' hometown, which leads consequently mislabeled products. The present study investigates capability DNA metabarcoding locate geographical origin honey. molecular markers (ITS2 and rbcL) allowed identification 926 plant species studied samples. A comprehensive review floristic reference...
Abstract Predicting species‐level effects of climatic changes requires unraveling the factors affecting spatial genetic composition. However, disentangling relative contribution historical and contemporary drivers is challenging. By applying landscape genetics species distribution modeling, we investigated processes that shaped neutral structure Oriental beech ( Fagus orientalis ), aiming to assess potential risks involved due possible future in species. Using nuclear microsatellites,...
New pollen evidence from two sites in South-Central Zagros (Lake Maharlou), Southwestern Iran, and Sahand Mountains Almalou), Northwestern provide for the emergence of tree cultivation Iran since 3rd 2nd millennia BC upland agricultural activities 5th to centuries BC. Juglans cf. regia could have been cultivated firstly at ~ 2500 became more extensively 1200 Platanus orientalis was also probably very early 1900 during Middle Elamite period (2800-550 BC) widely along with Juglans. The latter...
Iran is one of the largest honey-producing countries worldwide and considered as an important source honey for international markets. However, since not registered export to Europe, quality Iranian remains unknown European traders. As first step in filling this gap, we analyzed 225 samples using palynology, sensory, nuclear magnetic resonance (NMR) conventional physicochemical analyses outlined by Union coordinated control plan. The results show that while various types genuine unifloral can...
Iran, situated in Southwest Asia, showcases a diverse landscape, including three phytogeographical regions and two global biodiversity hotspots. This diversity is attributed to its intricate geology, mountainous terrain, wide altitudinal range, heterogeneous climate, fostering rich flora characterized by significant proportion of endemism. We present an updated version the Vegetation Database Iran (IranVeg) (GIVD ID AS-IR-001), comprising 13,411 plots spanning six major habitat types. These...
Palynological analysis and radiocarbon dating of a short sediment core from high-altitude mire in the Arasbaran area northwestern Iran reveals long-term vegetation dynamics, climate change anthropogenic impact. Our findings indicate prevalence semi-desert steppe vegetation, with variety Asteraceae – mainly Lactuceae species 3000 to 1440 cal yr BP. This period is followed by higher occurrence Artemisia spp. Brassicaceae (1440–1330 BP), re-expansion (1330–1030 BP) (1030–330 and, finally,...
Abstract Past vegetation, fire, and climate dynamics, as well human impact, have been reconstructed for the first time in highlands of Gilan province Alborz mountains (above Hyrcanian forest) last 4,300 cal yrs bp . Multi-proxy analysis, including pollen, spores, non-pollen palynomorphs, charcoal, geochemical has applied to investigate environmental changes at 2,280 m a.s.l., above forest. Dominant steppe vegetation occurred study area throughout recorded period. The formation studied mire...
ABSTRACT Palynological and geochemical analyses provide valuable information about modern past climatic regimes vegetation. The impact of climate humans on vegetation in the semi‐arid areas northwestern Iran has received increased interest wake warming temperatures Middle East. down‐core XRF elemental abundances from a peat core Lake Neor enabled reconstruction vegetational changes 7000 years over highlands Iran. Periods arboreal pollen (AP) types high ( Artemisia + Poaceae)/Chenopodiaceae...

Journal of Coastal Research, 37(3), 611–619. Coconut Creek (Florida), ISSN 0749-0208.The forest has been recognized as a hotspot biodiversity an important refugium broad-leaved trees that survived from Quaternary ice ages. However, nowadays this ecosystem endangered due to increased impacts. Multiproxy analysis,...
شناخت ویژگیهای جنگلشناسی تودههای جنگلی مقدم بر هرگونه اقدام مدیریتی در جنگل است. پژوهش پیشرو با هدف تعیین تیپهای و بررسی مهم تودهها امتداد گرادیان ارتفاعی جنگلهای حفاظتشده ارسباران انجام شد. بدینمنظور، قطعهنمونههای دایرهایشکل 400 متر مربعی فواصل 50 متری، پنج خطنمونه به فاصله 100 از یکدیگر، پایینترین حد (1100 متر) تا بالاترین (1725 گسترش پیاده شدند. هر قطعهنمونه، پس عاملهای فیزیوگرافی (شیب، جهت دامنه، ارتفاع مختصات جغرافیایی)، گونههای گیاهی چوبی شناسایی قطر برابر سینه کلیه...
