چکیده | ||
پرندگان آشیان حفرهای بهعنوان شاخص تنوع پرندگان این اکوسیستمهای جنگلی هستند، بنابراین برای کمک به حفاظت از تنوع زیستی پرندگان در این جنگلها در مطالعه حاضر با به کارگیری مدلهای توزیع گونهای اثرات تغییرات اقلیمی بر توزیع دارکوب خالدار بزرگ بررسی و پوشش مناطق حفاظتشده برای زیستگاههای مطلوب گونه در جنگلهای هیرکانی موردمطالعه قرار گرفت. در این مطالعه از رویکرد انسمبل با بهرهگیری از سه روش مدلسازی یعنی روش بیشینه آنتروپی، جنگل تصادفی و درخت سازشی تعمیم یافته استفاده شد. نتایج حاصل نشان داد که در حال حاضر مساحت زیستگاههای مطلوب این گونه 29858 کیلومترمربع است و برای سال 2070 به 30805 و برای سال 2100 به 34392 کیلومترمربع افزایش خواهد یافت. در واقع مطالعه حاضر نشان داد که تحت تأثیر تغییرات اقلیمی زیستگاههای مطلوب برای دارکوب خالدار بزرگ افزایش خواهد یافت. همچنین بررسی پوشش مناطق حفاظتشده نشان داد که 15 درصد از زیستگاههای مطلوب گونه در گستره مناطق حفاظتشده قرار دارند. | ||

چکیده [English] | ||
Hyrcanian forests are rich in the sense of biological diversity. Cavity-nesting birds are considered an indicator of bird diversity in these forest ecosystem. To help conservation of avian diversity in Hyrcanian forests, we applied ensemble of three species distribution models (Generalised Boosted Models, Maximum Entropy modeling, Random Forest) and predicted the impacts of climate change on distribution of Dendrocopos major an important tree-cavity nesting bird in the area. We also estimated protected areas coverage for suitable habitat of the species in Hyrcanian forests. Results showed that area of suitable habitat of the species is and this will increase to 30805 by 2070 and 34392 by 2100. We also found that 15 percent of the species suitable habitat covered by protected areas. | ||
