in the present study, mitochondrial dna polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) assay was used to assess the population structure and genetic relationships among six persian sturgeon, acipenser persicus populations from south caspian sea along the iranian coast. the complete nucleotide dehydrogenase subunit 5 (nadh 5) region of mtdna amplified by pcr was di...

Each year landscape fires across the globe emit black and organic carbon smoke particles that can last in the atmosphere for days to weeks. We characterized the climate response to these aerosols using an Earth system model. We used remote sensing observations of aerosol optical depth (AOD) and simulations from the Community Atmosphere Model, version 5 (CAM5) to optimize satellitederived smoke ...

[1] Multiple mechanisms have been suggested to explain seaward motion of the south flank of Kīlauea Volcano, Hawai‘i. The consistency of flank motion during both waxing and waning magmatic activity at Kīlauea suggests that a continuously acting force, like gravity body force, plays a substantial role. Using finite element models, we test whether gravity is the principal driver of long-term moti...

The Black, Azov, Caspian and Aral Seas, remnants of the intracontinental Paratethys basin, are home to a spectacular diversity of crustaceans. This study examines the past history of the Ponto-Caspian fauna through comparative phylogeographical studies on both benthic and planktonic taxa, based on an examination of nucleotide diversity in the mitochondrial, cytochrome c oxidase subunit 1 (COI) ...

It is estimated that 90% of sewage in cities in developing countries are today discharged untreated into water bodies. The physical, biological, chemical and geologic interactions among different components of the environment that occur within a wetland. Anzali wetland complex is a good example of a natural wetland, characteristic of the South Caspian lowlands. It supports an extremely diverse ...
