The survival of isolated small populations is threatened by both demographic and genetic factors. Large carnivores declined for centuries in most of Europe due to habitat changes, overhunting of their natural prey and direct persecution. However, the current rewilding trends are driving many carnivore populations to expand again, possibly reverting the erosion of their genetic diversity. In thi...
Previous molecular phylogenetic studies have examined the taxonomic relationships among a number of typical emberizid sparrow genera. To help clarify these relationships, we sequenced a 1673 base pair fragment for the complete sequence of three mitochondrial genes: adenosine triphosphatase (Atp8 and Atp6) and cytochrome oxidase subunit III (COIII) for 38 sparrow species, along with Passerina am...
Many phylogenetic questions in the Ciconiiformes remain unresolved and complete mitogenome data are urgently needed for further molecular investigation. In this work, we determined the complete mitogenome sequence of the little egret (Egretta garzetta). The genome was 17,361 bp in length and the gene organization was typical of other avian mtDNA. In protein-coding genes (PCGs), a C insertion wa...
رآیند ردوکس زوج nadh/nad+ که در بیش از 330 آنزیم دی هیدروژناز است در سال های اخیر از موضوعات مهم تحقیقاتی بوده که دارای کاربردهای تجزیه ای و زیستی است. در این کار ما از الکترود کربن شیشه ای اصلاح شده با نانوصفحات گرافن و کمپلکس روتنیوم شامل لیگاند 1و 10 -فنانترولین 5و 6- دی اون به عنوان بستری مناسب برای اکسایش الکتروکاتالیتیکی nadh بکار گرفته شده است. رفتار الکتروشیمی الکترود اصلاح شده به وسیله...
The southern coast of Australia is composed of three distinct biogeographic provinces distinguished primarily by intertidal community composition. Several ecological mechanisms have been proposed to explain their formation and persistence, but no consensus has been reached. The marine clam Lasaea australis is arguably the most common bivalve on southern Australian rocky shores and occurs in all...
Chitosan (Ch)-derived from biowaste along with smectite, an abundant clay mineral, were used in a low-cost and eco-friendly synthesis of new type catalyst. Nanocomposite catalysts constituted Co supported on smectite chitosan-derived carbon loading obtained using impregnation?carbonization procedure denoted as Co/cCh-S-T (T stands for applied carbonization temperature). The was performed the te...
