Alburnus sava, new species, is described from the Kolpa River. The Kolpa is a tributary of the Sava, a major tributary of the Danube River, in the Black Sea basin. Alburnus sava is distinguished from its congeners in the Danube drainage, A. mento and A. sarmaticus, by having 23-27, usually 24-26, gill rakers; the ventral keel usually completely covered by scales (scaleless part maximum 15% of t...
The objective of this study was to examine the spatial genetic relationships of the Lake Qinghai scaleless carp Gymnocypris przewalskii within the Lake Qinghai system, determining whether genetic evidence supports the current taxonomy of Gymnocypris przewalskii przewalskii and Gymnocypris przewalskii ganzihonensis and whether Gymnocypris przewalskii przewalskii are returning to their natal rive...
Pisione is a scaleless group of small scale worms inhabiting sandy bottoms in shallow marine waters. This group was once considered rare, but now 45 described species can be characterized, among others, by their paired, segmental copulatory organs (one to multiple external pairs), which display a complexity of various accessory structures. The evolutionary significance of these unique organs wa...
Pisionidae is a group of interstitial worms whose phylogentic affinities have been enigmatic. They have been allied to different Phyllodocida taxa. Although originally associated with Glyceridae and Phyllodocidae, they are more recently considered to be related to scale worms. Scale worms are a well-defined taxon, Aphroditiformia, within Annelida due to the unique possession of dorsal scales ca...
بیماری میوه سبز مرکبات توسط باکتری سخت کشت candidatus liberobacter asiaticus ایجاد می شود که اولین بار در چین توصیف شده است و در سال 1919 با نام رسمی huanglongbing معرفی گردید. این بیماری یکی از پرخسارت ترین بیماری های مرکبات درجنوب شرقی آسیا، شبه قاره هند، آفریقای جنوبی و شبه جزیره عربستان است. این بیماری در سال 1386 از جنوب ایران گزارش گردید. برای درک مکانیسم مولکولی برهمکنش میزبان-پاتوژن از ...
