Remotely sensed imagery is proving to be a useful tool in estimating water depths in coastal zones. On the other hand, many coastal zone studies in the southern part of the Caspian Sea are only concerned with areas of shallow water and would benefit from easily updated bathymetric estimates. In this study, we tested three different methods for extracting bathymetry information from Landsat 5 da...

The Middle East contains a great diversity of Capoeta species, but their taxonomy remains poorly described. We used mitochondrial history to examine diversity of the algae-scraping cyprinid Capoeta in Iran, applying the species-delimiting approaches General Mixed Yule-Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examine...

BACKGROUND Lipases (acylglycerol acylhydrolase, E. C. 3. 1. 1. 3) are widely distributed among microorganisms, animals and plants, catalyzing the hydrolysis of triglycerides to free fatty acids and glycerol. Their commercial application includes pharmaceutical, chemical, and paper industries. OBJECTIVES This study aimed to isolate and screen lipolytic fungi from coastal waters of the southern...

BACKGROUND Drowning is a serious but neglected health problem in low-and middle-income countries. OBJECTIVES To describe the effectiveness of drowning prevention program on the reduction of drowning mortality rates in rural settings at the north of Iran, and guide its replication elsewhere. PATIENTS AND METHODS This interventional design included pre- and post-intervention observations in t...

after the soviet union fragmentation, the attentions of regional and international countries have turned to this region for oil and gas discovery in the caspian basin. after that, this region enjoys more geopolitical importance increasingly. therefore, the main question is:” what factors can influence the new geopolitics of the caspian basin?” it seems that, some issues such as the lack of a...

Ecosystems in the Caspian Sea region have been heavily modified by anthropogenic activities, mainly as a result of changes in the water flow and degradation of the water quality in the ecosystems. Changes in the regional environment have influenced regional economies, particularly obvious in the impacts on fish stocks. Using the methodology developed in the GIWA project, experts in the region c...
