Abstract

In this study, a new morphospecies, Hapalosiphon fontinalis (C. Agardh) Bornet (Stigonemataceae, Stigonematales) is reported for Iran. Identification was done in a multidisciplinary way including morphological variations in relation to pH and carbon dioxide concentration fluctuations at limited irradiance (2 μE m-2 s-1). Regarding biological versatility of Cyanophyta, it has been tried to emphasize on the most prominent traits for identification and determination. A new description of the species has been presented regarding morphological characterization in Golestan Province.

Abstract [Persian]

در این مطالعه، یک گونه جدید Hapalosiphon fontinalis (C. Agardh) Bornet از خانواده و راسته Stigonemataceae, Stigonematales، برای اولین بار از ایران گزارش شده است. شناسایی با روش چند وجهی شامل تنوع مورفولوژیکی در ارتباط با تغییرات اسیدیته و غلظت دی‌اکسید کربن در شرایط محدود نوری (µE m-2s-1 2) صورت پذیرفت. نظر به تنوع بیولوژیکی سیانوفیتا، سعی بر تاکید بر ویژگی‌های غالب برای شناسایی بوده است. در این مقاله توصیفی جدید از گونه Hapalosiphon fontinalis در ارتباط با ویژگی‌های مورفولوژیکی در استان گلستان بیان شده است.
