Persian gazelle, Gazella subgutturosa, exists throughout arid and semiarid regions of Iran and has a key role in these frail ecosystems. Habitat degradation and population decline has placed it on the list of vulnerable species in 2008. The phylogenetic relationships of three Persian gazelle populations in the central part of Iran (i.e. Ghamishlou National Park and Wildlife Refuge, Mouteh Wildl...
Pyrrolizidine alkaloids (PAs) are natural phytotoxins found in thousands of plant species around the world. They are probably the most common poisonous plants affecting livestock, wildlife and humans. The disease occurs almost entirely as a consequence of chronic poisoning and in general ends fatally. In the present study, PAs poisoning was investigated in a gazelle with hepatic encephalopathy ...
Bovids represent a convenient group for studying the acoustical variation, functions and evolution of vocal communication. Among bovids, a wide spectrum of vocal adaptations and examples of parallel evolution with cervids and humans can be found (Fitch & Reby 2001; McElligott et al. 2006; Frey et al. 2007, 2008a,b). For instance, in the goitred gazelle (Gazella subgutturosa), a strong sexual di...
Different species of gazelles are among the most endangered mammals on the Asian steppes and occur in the central, southern and northwestern regions of Iran. The previous conservation efforts in this region have been incomplete due to confusion about the phylogenetic relationship among various populations. So that, different conservation programs such as ex-situ breeding and transfer of captive...
a study was conducted to determine habitat suitability of goitred gazelle (gazella subgutturosa) in kalmand-bahadoran protected area during four seasons of year 2003-2004.the geographic position of dispersal points of gazelle herds was recorded with global position system. the data were transmitted into attributed tables in arc view software and their layers were created. the maps of slope, alt...
gharaviz no hunting area is known as one of the most important habitats of persian gazelle (gazella subgutturosa subgutturosa) in west zagros mountains. developing models to predict the distribution of wildlife is suitable tool for conservation and management. in this approach, the boundary of the study area was considered the distribution area and then were compared with actual region. field d...
تعیین وضعیت پراکنش گونههای حیاتوحش، وضعیت زیستگاههای تحت اشغال آنها و زیستگاههایی که شرایط حضور گونه را دارند به کمک روشهای ارزیابی زیستگاه از اهمیت بسزایی در مدیریت حیاتوحش برخوردار است. بهمنظور مدلسازی مطلوبیت زیستگاه آهوی ایرانی (Gazella subgutturosa subgutturosa) از روش حضور/عدم حضور با استفاده مدل شبکه عصبی پرسپترون چندلایه (MLP) استفاده شد. بهمنظور مدلسازی در منطقه شکارممنوع قر...
Modeling of ecological connectivity across landscape is important for understanding a wide range of ecological processes. Modeling ecological connectivity between habitats and incorporating these models into conservation planning require quantifying the effect of spatial patterns of landscape on the degree of habitats connectivity. Recently, concepts from electrical circuit theory have been ad...
یکی از مهمترین تدابیر در حفظ حیاتوحش هر منطقه، وجود آب و غذای کافی برای آن است. با توجه به اهمیت خاص گونه آهوی ایرانی (Gazella Subgutturosa Subgutturosa) در غرب ایران، بهخصوص در منطقه شکارممنوع قراویز و حضور دامهای روستاییان و عشایر در منطقه و هم چنین اهمیت عامل آب و پراکندگی آن بهعنوان یکی از منابع مهم زیستگاهی گونههای بیابانی و کویری، این تحقیق در پی یافتن من...
