معرفي الگوريتم ساده براي بررسي تنوع و پراكنش جلبك‌هاي ايران

Simple algorithm to assess the diversity and distribution for algae of Iran

با بررسي گزارش‌هاي معتبر از جلبك‌هاي نقاط مختلف كشور طي 87 سال اخير، اطلاعات حدود 6000 ركورد دربرگيرنده تعداد 2567 گونه جلبك مورد ارزيابي قرار گرفت و نقشه پراكنش آن‌ها ترسيم گرديد. هدف اصلي در اين پژوهش، طراحي يك ابزار تحقيق براي پاسخگويي به پرسش‌هاي ذيل مي‌باشد: 1- چگونه مي‌توان براي فهرستي انتخابي از جلبك‌ها، نقشه پراكنش ترسيم نمود؟ 2- آيا مي‌توان در هر مرحله از كاوش، تعداد هر يك از سطوح آرايه‌ها را نظير: جنس، گونه، جنس فاقد گونه (sp.)، زيرگونه، واريته و فرم را محاسبه نمود؟ 3- چگونه با حركت مكان‌نما روي نقشه ايران، مختصات جغرافيايي را همانند دستگاه GPS مشاهده نمود و اطلاعات جلبك‌هاي گزارش شده از يك محدوده خاص را بازيابي نمود؟

By studying algae reports from different localities of the country during the past 87 years, about 6000 records information including 2567 species and infra-specifics were analyzed and distribution maps were drawn. The algae studies in the Iranian islands of the Persian Gulf, especially around Bushehr and the Khark Island by Borgesen (1930), the oldest available document is used in this study. Many of the scientific names of the references used were synonyms with authorities in the field of algae taxonomy, such as AlgaeBase (Guiry & Guiry 2015) were changed to valid names. Using the capabilities VB.Net programming (Foxall 2015) under a model of software named as “Explorer for Algae of Iran” was designed and developed. The main targets of this study and making utilities and technical options related to the three essential questions are as follows: 1. How can plot distribution maps for selected algae species? 2. How can view the geographic coordinates of the points in DMS by moving the cursor on the map and related list of species and documented information for selected area? 3. How can the taxa levels such as genus, species, subspecies, varieties, and forms in search mode could be computed simultaneously?
