Determining suitable habitats is important for the successful management and conservation of plant and wildlife species. Teucrium polium L. is a wild plant species found in Iran. It is widely used to treat numerous health problems. The range of this plant is shrinking due to habitat destruction and overexploitation. Therefore, habitat suitability (...

Currently, the spread of coronavirus has affected almost the world and all cities in Iran. In this regard, the present study was conducted to analyze the rate of cases and mortality due to the COVID-19 virus in Iran and the world. Moreover, a comparison was made between the mortality rates due to COVID-19 and the 34 leading causes of mortality worl...

Land surface temperature (LST) is an important climate indicator that shows the relationship between the atmosphere and land. Due to environmental problems, including global warming, determining the relationship between natural factors and LST is urgent. This study aimed to model LST using a random forest-RF model and several independent factors, t...
Chapter
The aim of this study was to evaluate the association between the occurrence of Teucrium polium species and environmental variables to forecast habitat suitability. For species distribution modeling (SDM), three important steps have been taken: (I) identification of locations of Teucrium polium in the field, (II) preparing thematic predictors in GI...

The interspecific plant interactions along grazing and aridity stress gradients represent a major research issue in plant ecology. However, the combined effects of these two factors on plant-plant interactions have been poorly studied in the northeast of Iran. To fill this knowledge gap, 144 plots were established in 12 study sites with different g...

Aims Understanding fine-grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of fine-grain richness values of Palaearctic open habitats for vascular plants, bryophytes, lichens and complete vegetation (i.e., the sum of the...

We used three state-of-the-art machine learning techniques (boosted regression tree, random forest, and support vector machine) to produce a multi-hazard (MHR) map illustrating areas susceptible to flooding, gully erosion, forest fires, and earthquakes in Kohgiluyeh and Boyer-Ahmad Province, Iran. The earthquake hazard map was derived from a probab...
Preprint
Aridity and intensive grazing have been confirmed to affect the facilitative effects of dryland shrubs. However, their combined effects on plant-plant interactions have rarely been tested. To test how these two factors affect relations between plants, we analyzed 144 plots (under shrub canopy vs. open areas) at 12 sampling areas established in the...

Questions (i) Do patterns of species diversity and composition differ between the plots exposed to high versus low grazing intensity? (ii) Do these differences vary among three regions with different climate, representing the gradient from the arid to sub‐humid conditions? Location northeastern Iran Methods We compared plots intensively grazed by...

Researches related to invasive plant ecology has recently increased, hence the terminology used in the early studies can later be perused by other researchers. Incorrect use of the term "invasive species" instead of "non-invasive species" may lead to environmental consequences and threatens the biodiversity and life of endangered species. Therefore...

Understanding the responses of vegetation characteristics and soil properties to grazing in different precipitation regimes is useful for the management of rangelands, especially in the arid regions. In northeastern Iran, we studied the responses of vegetation to livestock grazing in three regions with different climates: arid, semiarid, and subhum...

Hello,
I used Monmonier's difference algorithm to assess its genetic discontinuities based on the Euclidean distance of genetic dataset and geographical coordinates of populations, using the monmonier function of the R adegenet package. The Gabriel graph was used to construct connection network for species populations using the chooseCN function. To reduce noise, I performed a principal component analysis (PCA) for the Euclidean distance of genetic data using the dudi.pco function in the R ade4, whose first eigenvalue was further adopted for the Monmonier algorithm. Now I need to see how stable such identified barriers are. A bootstrap approach should be used, i.e., running the analysis over XY bootstrap replicates.
Does anyone know how the monmonier function in adegenet R package runs over bootstrap pseudo-datasets? With which package and function of R?

Romania has the largest area of virgin forests in the whole of the EU. However, more than 60% of the assessments of forest and woodland habitats and species listed in the habitats reveal a bad or inadequate conservation status. Urbanization, with consequent impacts on environmental resources and human well-being, has a strong influence on plant distribution. Also, with climate change, however, area-based conservation faces the challenge that the geographic ranges of species will shift. Species distribution models (SDMs) can help predict how climate change and other human-induced threats will impact the future range dynamics of plant species. Therefore, in this project, we focus on delineating the potential distribution of species based on associations between species occurrences and environmental conditions, mostly climate.
