The objective of this study was determining the heavy metal contents in sediment along the coastlines of Hormuzgan province. Sediment constitutes are important part of aquatic ecosystems. They provide habitat for benthic organisms and could be a significant sink as well as a potential source of contaminants. Three sources of heavy metals pollution in this area are industry, natural mineral...

The Persian Gulf, a young and shallow epicontinental sea, is known for its unique geological oceanographic characteristics that foster diverse productive marine ecosystems. A substantial portion of the Gulf’s seafloor consists unconsolidated soft sediments, making it unsuitable colonization by many sessile organisms. Consequently, relatively few hard grounds submerged banks provide suitable hab...

چکیده   این مطالعه با هدف بررسی الگوی پراکنش و تعیین فراوانی فصلی و زیستگاهی خرچنگهای منزوی در شش ایستگاه واقع در ناحیه جزر و مدی جزیره هرمز انجام پذیرفت. نمونهبرداری در یک دوره یک ساله و در چهار فصل انجام شد. خرچنگ منزوی در اتانول 70 % تثبیت و به آزمایشگاه منتقل شدند. با استفاده از کلیدهای شناسایی معتبر 9 گونه متعلق به دو خانواده از خرچنگهای منزوی مورد شناسایی قرار گرفت. آنالیزهای آماری با است...

with regard to bycatch problem, this is the first study of the shrimp trawl bycatch in different depth variation in hormuzgan coastal waters. samples were collected during shrimp season in october 2011 and november 2012. the study area was divided into two regions: hormuz-keshtisoukhte (56°, 27ʹ e/27°, 07ʹ n) to (56°, 18ʹ e/27°, 06ʹ n) and keshtisoukhte-toola (56°, 18ʹ e/27°, 06ʹ n) to (55°, 58...

rocky shores are one of the most important habitats of marine environment in coastal areas. they host marine organisms including seaweeds because of existence of strong and stable substrate for their growths. intertidal rocky shores are a prominent feature on coastal areas of qeshm island located at the northern part of strait of hormuz. in order to study biomass of seaweeds on rocky intertidal...
