Surveying vegetation is essential for documenting plant diversity, especially for coastal vegetation that results among the most threatened ecosystems globally. To support conservation and management programs, we developed the SALt-affected vegeTatIon dataset of Tuscany coaStal Habitats (SALTISH). This dataset comprises 734 newly sampled vegetation...
Aim
Pollen assemblages are widely used to infer paleoenvironment features, aiming at reconstructing both past climates and biomes. However, the functional link between environmental conditions and pollen assemblages is not straightforward and requires thorough testing to be used confidently. Here, we use a trait‐based approach to assess the consist...
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, and heterogeneous climate, fostering a rich flora characterized by a significant proportion of endemism....
Plant communities are composed of species that differ both in functional traits and evolutionary histories. As species’ functional traits partly result from their individual evolutionary history, we expect the functional diversity of communities to increase with increasing phylogenetic diversity. This expectation has only been tested at local scale...
Zelkova (Ulmaceae) represents a relict woody genus comprising six extant species with a disjunctive distribution in eastern and southwestern Eurasia. Zelkova carpinifolia is a deciduous tree limited to the Caucasian Ecoregion and its surroundings. Most of its sites are located in the two essential Tertiary
refugia of the Northern Hemisphere – Colch...
Endemic species are more impacted by climate change than other taxa. However, assessing the vulnerability of endemics to these changes in some regions, such as the Hyrcanian forest, is limited, despite its importance for biodiversity and ecosystem function. To address the question of expected habitat shifts under climate change across the Hyrcanian...
Introduction: The use of medicinal plants is a part of the culture of indigenous people is considered as an
important pharmaceuticals source. Traditional botany provides valuable approaches to find new medicinal
plants and plant-based pharmaceuticals.
Aim: The aim of this study was to identify the medicinal plants of Rudsar and Amlash and to introd...
Aims
Oak–hornbeam forests and related vegetation types (phytosociological order Carpinetalia betuli ) are widespread in temperate western Eurasia. However, their national classification systems are poorly compatible, and a broad‐scale classification based on numerical analyses is lacking. Therefore, we aimed to establish a unified formalized classi...
Understanding how environmental factors shape patterns of genetic and phenotypic variations in a species is necessary for conservation and plant breeding. However, these factors have not yet been completely understood in tuberous orchid species used to make ‘Salep’, an important ingredient in traditional medicine and beverages in middle eastern cou...
Predicting species-level effects of climatic changes requires unraveling the factors affecting the spatial genetic composition. However, disentangling the relative contribution of historical and contemporary drivers is challenging. By applying landscape genetics and species distribution modeling, we investigated processes that shaped the neutral ge...
Understanding forest understorey community response to environmental change, including management actions, is vital given the understorey's importance for biodiversity conservation and ecosystem functioning. The Natural World Heritage Hyrcanian temperate forests (Iran) provide an ideal template for furnishing an appreciation of how management actio...
Aim
To analyse the biogeographic patterns of Temperate Deciduous Forests (TDFs) in Western Eurasia based on different life‐forms and forests layers and explore their relationships with the current climate, Last Glacial Maximum (LGM) climate and topography.
Location
Western Eurasia.
Taxon
Vascular plants.
Methods
We delimited nine regions encompa...
Motivation
Assessing biodiversity status and trends in plant communities is critical for understanding, quantifying and predicting the effects of global change on ecosystems. Vegetation plots record the occurrence or abundance of all plant species co‐occurring within delimited local areas. This allows species absences to be inferred, information se...
Aim
This work explores whether the commonly observed positive range size–niche breadth relationship exists for Fagus, one of the most dominant and widespread broad‐leaved deciduous tree genera in temperate forests of the Northern Hemisphere. Additionally, we ask whether the 10 extant Fagus species’ niche breadths and climatic tolerances are under p...
Hops (Humulus lupulus L.) is an indispensable material for beer brewing with a high demand for novel genetic resources. Given the ongoing extreme exploitation as well as mismanagement in the Hyrcanian forests, home of hops new germplasm in the north of Iran, there is a necessity to detect possible influential factors on the distribution pattern of...
Aims
To develop forest vegetation classification at the level of alliances and associations across the Hyrcanian ecoregion, Northern Iran, and to explore the effects of main environmental and geographic gradients on their distribution.
Location
Hyrcanian ecoregion, Northern Iran.
Methods
A database of 1,597 vegetation plots of mostly 400 m ² in s...
The Hyrcanian forests in northern Iran are biogeographically unique natural closed-canopy temperate deciduous forests. Although many vegetation and floristic studies were carried out in these forests, a comprehensive phytosociological analysis is still outstanding. For this purpose, we created a database (GIVD ID: AS-IR-006) using the TURBOVEG soft...
Hyrcanian forests in northern Iran have important tree and shrub elements of Euro-Siberian and rare forest communities, among them beech community widely covers the mountainous forests from Western to Eastern (Gorgan) Hyrcanian region. In order to identify the floristic characteristics and affecting factors on the species richness in pure beech sta...
Peucedanum hyrcanicum Gholizadeh, Naqinezhad & Mozaff. (Apiaceae) is described here as a new species. It grows at high elevations on rocky cliffs and outcrops in forests and shrublands of the Hyrcanian relict region in northern Iran. It differs from other Iranian Peucedanum s. lato species in the shape and size of leaves, leaflets, umbels, fruits a...
The Abshar protected area with 3639 ha and an altitude ranging from 400-855 m a.s.l. is one of the forest areas that
due to its topography is covered by Carpinus betulus, Parrotia persica and Diospyros lotus speices. The floristic study
of this area is long with sampling plots. The floristic-physiognomic investigation showed that flora of this regi...
We investigated the floristic composition of the Hyrcanian forests and the related forest-steppe ecotone in Northern Iran by using two long ecological transects, from lowland to upper mountain areas. The study was conducted during 2008 and 2009 and yielded the identification of 395 plant taxa belonging to 233 genera and 78 families. Dicots with 300...
Species diversity is one of the most important indices for evaluating the stability and productivity of forest ecosystems. The aim of this research was to recognize ecological species groups and to determine the relationship between environmental variables and the distribution of ecological species groups. For this purpose, 25 400-m2 releves were s...
The mesic Caspian (Hyrcanian) forest and ecotone communities provide a marked contrast to the arid and semiarid landscapes associated with most of the territory of Iran. To date, the ecological characteristics of these habitats, threatened and of conservation importance, have been little studied. Accordingly, ecological profiles of some important p...
Semeskandeh and Dasht-e Naz, two lowland wildlife refuges for threatened Hyrcanian forests were selected for a pilot phytosociological investigation. Forty relevés from these conservationally important lowland remnant forests have been classified by the modified TWINSPAN and synsystematically treated following the Braun-Blanquet approach. Two assoc...
