Taxonomic study of the genus Padina (Dictyotales, Phaeophyceae) from the Persian Gulf coast was conducted based on morphology and molecular phylogenetic analyses using chloroplast encoded large subunit RuBisCo (rbcL) gene sequences. Detailed descriptions of each species found in this study are described. Several morphological characters, such as number of cell layers composing the thallus, pr...

the foremost constant and incessant social development in history of persian gulf is “immigration and population displacement” at both sides of this region. this phenomenon is so important that no one may comprehend properly the events and incidents occurred in this region particularly at pre- petroleum exploration regardless of investigation and considering this issue in mind. if we divide per...

A total of 299 fish belonging to ten teleost species were studied in Iranian waters at the north-eastern coast of the Persian Gulf for larval trypanorhynch cestode infection. The following trypanorhynch species were identified: Callitetrarhynchus gracilis Pintner, 1931, Pseudogilquinia thomasi (Palm, 2000), Pterobothrium lesteri Campbell and Beveridge, 1996 and Pseudolacistorhynchus shipleyi (S...

Persian Gulf and its coastal areas are the world's largest source of crude oil and related industries govern the region. One of the contaminants in this area is heavy metals associated with oil spill. More importantly, vanadium, nickel and zinc can be named in this regard. In this study, the contamination of northern coasts of Persian Gulf is selected to investigate for trace metals of V, Ni, C...

Seventy species of opisthobranchs are described in this work based on collections from the Persian Gulf, Socotra, Kenya, Zanzibar, Madagascar, La Réunion, Mauritius, the Seychelles, the Maldives, and Sri Lanka. Ten species are newly recorded from the western Indian Ocean and four species are recorded in the scientific literature for the first time since their original descriptions. Two species ...

A Cochlodinium polykrikoides red tide occurred in northern coastal waters of the Persian Gulf which killed million tons of fish and benthic animals. This study reports high mortality rate of Solen dactylus (razor clam) populations on the Golshahr coast of Bandar Abbas to show that management and monitoring plans are necessary to prevent future mass mortalities. Specimens of S. dactylus were col...

The Persian Gulf is an important economic and geo-political region. Owing to its oil and gas resources, it is one of the busiest waterways in the world. There are many operating oil wells in the northern part of the Persian Gulf . As a result, the risk of contaminant dispersion is high. The deliberate discharge of 6.3 million barrels of crude oil during the 1991 war against Kuwait in this regio...

Seaside Sparrows (Ammodramus maritimus) along the Gulf of Mexico are currently recognized as four subspecies, including taxa in Florida (A. m. juncicola and A. m. peninsulae) and southern Texas (Ammodramus m. sennetti), plus a widespread taxon between them (A. m. fisheri). We examined population genetic structure of this "Gulf Coast" clade using microsatellite and mtDNA data. Results of Bayesia...

A RECENT ISSUE of Systematic Zoology (1960, vol. 9, nos. 3, 4 ) was ' devoted entirely to a symposium entitled "The Biogeography of Baja California and Adjacent Seas." One recurring theme was the affinity between forms occurring on the Pacific Coast in the Californian province (Hubbs, 1960: 134), and those in the northern part of the Gulf of California. Between these areas, in the main part of ...
