[ 1 ] - اثرات آتش‌سوزی بر پویایی پوشش‌گیاهی در مراتع نیمه‌استپی (مطالعه موردی: مراتع بویین و میاندشت استان اصفهان)
یکی از عوامل مهم در تعیین ساختار و ترکیب جوامع گیاهی به ویژه در مراتع خشک و نیمه‌خشک، آتش‌سوزی می‌باشد. این مطالعه با هدف بررسی اثر آتش‌سوزی بر پویایی پوشش‌گیاهی در مراتع نیمه‌استپی زاگرس مرکزی انجام شد. نمونه‌برداری پوشش‌گیاهی به روش تصادفی طبقه‌بندی شده و در 6 سایت حریق شامل آتش‌سوزی یکساله و 5 ساله انجام شد. در هر سایت مرتعی، تعداد 20 پلات 4 متر مربعی مستقر شد که 10 پلات در منطقه حریق و 10 پ...

[ 3 ] - Distribution Modeling of Foraging Habitats for Egyptian Vulture (Neophron percnopterus) in Kermanshah Province, Iran
The Egyptian vulture, Neophron percnopterus, as a globally endangered species, is significantly affected by conflicts with human, leading to the decline of this species population. Availability of food resources is known as one of the most important factors affecting the distribution of the Egyptian vulture. In this study, we employed an ensemble modelling approach to predict the suitability o...
[ 4 ] - Predicting the impact of climate change on potential habitats of Stipa hohenackeriana Trin & Rupr in Central Zagros
Stipa hohenackeriana in terms of forage production and soil protection is especially important. In this study, was predicted the potential effects of climate change on the future geography distribution of this species in Chaharmahal va Bakhtiari province located in Central Zagros region. To do this, 122 species presence point of this species is collected by GPS, along with 9 environmental varia...
[ 5 ] - Modeling the current and future suitable habitat distribution of Fritillaria imperialis under climate change scenarios and using three general circulation model in Iran
Climate change may pose challenges to the conservation of plant species such as the Fritillaria imperialis that have narrow geographical distribution. In this study, the modeling suitable habitats of F.imperialis in Iran was done in the current condition and under climate change (2050). For this purpose, 78 species presence data along with 12 environmental variables including bioclimatic, physi...
[ 6 ] - Predicting the geographical distribution of Alopecurus textilis Boiss rangeland species on basis Consensus approach of climate change in Mazandaran province
The climate changes have an important role in distribution of plant species. Statistical species distribution models (SDMs) are widely used to predict the changes in species distribution under climate change scenarios. In the peresent study, the distribution of Alopecurus textilis in the current and future climate condition (2050) under the influence of climate change and two scenarios of RCP 4...
[ 7 ] - Modeling Current and Future Potential Distributions of Caspian Pond Turtle (Mauremys caspica) under Climate Change Scenarios
Although turtles are the most threatened taxonomic group within the reptile class, we have a very limited understanding of how turtles respond to climate change. Here, we evaluated the effects of climate changes on the geographical distribution of Caspian pond turtle (Mauremys caspica). We used an ensemble approach by combining six species distribution models including artificial neural network...
[ 8 ] - Potential geographic distribution of Prangos ferulacea (L.) Lindl. in Chaharmahal va Bakhtiari province under climate change scenarios
Prangos ferulacea (L.) Lindl is a perennial plant that besides fodder and medicinal values the plant can help to control soil erosion. There is little knowledge about the effect of climate change on the Prangos genus especially P. ferulacea. In this study, we used ensemble modeling based on five species distribution models to predict the potential effects of climate change on the future geograp...
