Abstract

The purpose of this study was to evaluate of bio diversity and density of brown algae in coast of Bushehr province in the Persian Gulf during warm and cold seasons. The most and lowest density of brown algae was in the spring (33±20Number in m2) and in autumn(17± 9Number in m2) respectively. The highest density was belonged to species of Cystoserria myrica with(41±25)and it was dominant species among the six species of brown algae were sampled. The most of Margalef index(0/438) was observe at the mid, and mid litoral zone. The maximum value of the Shannon index(0/94) was belonged to the low, mid litoral zone. Most of species richness and dominance was revealed at autumn and highest indices of Shannon(0/76) was at spring. Brown algae in the spring had the most density (33±20/86 Number in m2). Species richness was detected the highest and lowest in Nuclear power Plant and Ganaveh stations in two seasons respectively. Higher levels of dominance and low diversity was in within the tidal zone.
