Article
Full-text available
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...
Article
The herb Arctotheca calendula (capeweed) is reported as a new record for Iran. A detailed description, a distribution map, colour photographs of an herbarium sample, and diagnostic features are provided to facilitate identification. The species was first observed in 2017 in the Miankaleh Biosphere Reserve, one of the thirteen UNESCO Biosphere Reser...
Article
Full-text available
Species abundance distributions (SADs) link species richness with species abundances and are an important tool in the quantitative analysis of ecological communities. Niche based and sample based SAD models predict different spatial scaling properties of SAD parameters. However, empirical research of SAD scaling properties is largely missing. Here,...

Full-text available
The search for the Garden of Eden has been going on for centuries. However, no one has yet attempted to associate it with the occurrence of a specific natural type of vegetation. We are also not aware what its current state and chances of survival are. In this work, we try to define the vegetation of Paradise, to visualize its past and predict its...
Article

Dedicated insights into the diversity, spatial and temporal distribution of rice weed communities, as well as underlying ecological factors, are critical for developing effective ecological weed management strategies in these agroecosystems, leading to the preservation of biodiversity and ecosystem services in a sustainable agriculture framework. T...
Article
Full-text available
This vegetation–environmental relation study is the first large-scale survey along 34 cross-shore transects in 650 km-coastal dune remnants of the south Caspian Sea, Iran. The five vegetation zones dedicated here seem to be driven by both zonal (climate, distance to the sea and pH) and azonal (salinity) factors. To assess conservation status, diffe...
Chapter
Asia, occupying nearly 30% of the earth’s terrestrial surface, is one of the most important continent known for its highly diverse culture, economy, geography, and ecology. Three of the world’s five largest economies, and nearly two-thirds of the world’s population, are in Asia. The continent has a diverse range of habitats including tropical moist...

Trisetum spicatum, a widespread arctic and alpine species, is reported for the first time in the flora of Iran. This species was collected from scree habitats above 4000 m a.s.l. of Mt. Damavand (Central Alborz, Alborz range, N. Iran). This new occurrence of the species in the alpine area of Iran highlights the role of high mountains as migration c...

Article
Full-text available
Questions: Species-area relationships (SARs) are fundamental for understanding biodiversity patterns and are generally well described by a power law with a constant exponent z. However, z-values sometimes vary across spatial scales. We asked whether there is a general scale dependence of z-values at fine spatial grains and which potential drivers i...

Conceptual figure summarizing our hypotheses how different drivers could influence fine-grain β-diversity via changing mean occupancy of species, based on the findings of our study and theoretical considerations. Fine-grain β-diversity (and likewise for larger grain sizes) is mathematically linked to mean occupancy, which can be decomposed into (i)...
Article
Smoke and heat as germination cues are some of the most important drivers stimulating seed germination. However, the impact of germination factors from wildfire (i.e., smoke and heat) on the germination of species occurring in western Asia has rarely been investigated. We aimed to analyze the effects of different smoke and heat treatments on seed g...

Aim: Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains in continuous vegetation. We asked which function describes SARs best at small grains and explored how...

Biodiversity loss due to human activities has dramatically increased in the last decades, and attempts to protect threatened species should be accelerated. An important contribution towards this goal is to identify areas rich in biodiversity and endemism, where conservation will be most efficacious. Here, we follow this strategy for Iran, which inc...
Article
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.
