Protected areas are experiencing increased levels of human pressure. To enable appropriate conservation action, it is critical to map and monitor changes in the type and extent of land cover/use and habitat classes, which can be related to human pressures over time. Satellite Earth observation (EO) data and techniques offer the opportunity to detect such changes. Yet association with field info...
Background & Objectives: Mosquitoes (Diptera: Culicidae) are medically considered as one of the most important species of insects in terms of disease transmission to human beings; hence, they can be vectors of remarkable diseases such as malaria, West Nile, dengue fever, yellow fever, and filariasis. This study aimed to determine the species diversity and larval habitat characteristics of mosqu...
Presence-absence and abundance of each fish species in a river habitat depends on several factors and they prefer a specific range of each habitat factor. The present study was carried out to investigate habitat suitability index of Capoeta capoeta and the effect of habitat factors on its distribution and abundance in Roodbabol branch of the River Babolrood (Mazandaran Province). To do, fish sa...
ترانسفکت کردن سلول های استرومایی مغز استخوان با وکتور حامل ژن فاکتور نوروتروفیک مشتق از رده ی سلولی گلیال(gdnf) و ارزیابی بیان آن در محیط in vitro مقدمه : فاکتور نوروتروفیک مشتق از رده ی سلولی گلیال (gdnf) از مهم ترین پروتئین ها در رشد و ترمیم سیستم عصبی است. هر گونه نقص در تولید و ترشح این پروتئین موجب اختلالات مختلفی در بازسازی سلول ها در بیماری های مخرب سیتم عصبی می شود.از گزینه های درمانی ...
Given the rapidly growing human population in mediterranean-climate systems, land use may pose a more immediate threat to biodiversity than climate change this century, yet few studies address the relative future impacts of both drivers. We assess spatial and temporal patterns of projected 21(st) century land use and climate change on California sage scrub (CSS), a plant association of consider...
As the largest terrestrial biomes, crop and pasturelands can have very large positive or negative impacts on biodiversity and human well-being. Understanding how animals use and impact agroecosystems is important for making informed decisions that achieve conservation and production outcomes. Yet, few studies examine the tradeoffs associated with wildlife in agricultural systems. We examined bi...
