Global warming has increased the frequency of extreme climate events, yet responses of biological and human communities are poorly understood, particularly for aquatic ecosystems and fisheries. Retrospective analysis of known outcomes may provide insights into the nature of adaptations and trajectory of subsequent conditions. We consider the 1815 eruption of the Indonesian volcano Tambora and i...
three marine bacteria, pseudomonas putida ptcc 1664, bacillus cereus pttc 1665 and pseudomonas pseudoalkaligenes ptcc 1666 isolated from the east anzali wetland sediments of the caspian sea, were resistant to heavy metals of cadmium (cd), nickel (ni) and vanadium (v). pseudomonas pseudoalkaligenes ptcc 1666 was found to be resistant to all 3 metals ni, cd, v. heavy metal uptake was determined ...
Carbonic anhydrase-8 gene therapy inhibits the ITPR1-cytosolic free calcium pathway producing analgesia and anti-hyperalgesia Roy C Levitt, Gerald Z Zhuang, Benjamin Keeler, Jeff Grant, Laura Bianchi, Eugene S Fu, Yan Ping Zhang, Diana M Erasso, Jian Guo Cui, Tim Wiltshire, Qiongzhen Li, Shuanglin Hao, Konstantinos D Sarantopoulos, Keith Candiotti, Shad B Smith, William Maixner, Luda Diatchenko...
Iran’s security is affected by a broad region that includes the Caspian Basin, Central Asia, Afghanistan, the Persian Gulf states, Pakistan, Turkey, and the Middle East. However, an increased focus on the countries of the Economic Cooperation Organization (ECO), as well as Iraq, on the one hand, and with members of the Gulf Cooperation Council (GCC) (including Yemen) on the other, provides a na...
The underwater gamma-ray spectrometer KATERINA was calibrated in a special tank and then demonstrated the Southern Caspian Sea to determine radioactivity levels seawater as well sediment. simulated marine efficiency of situ detection system validated analyzing high energetic (1764 keV 214Bi 2614 208Tl) peaks using their known activity concentration determined from low energy emissions. analysis...
S U M M A R Y The Rudbar-Tarom earthquake of 1990 June 20 (M0 = 1.4 × 1027 dyn cm), the largest one in Iran over the past 35 yr, was accompanied by a small tsunami in the Caspian Sea, which produced run-ups of up to 2 m, and inundations of 1 km, reaffirming the existence of tsunami hazard along the Caspian shoreline, as suggested by historical reports. We present the results of a field survey, ...
Species can respond to climate change by tracking appropriate environmental conditions in space, resulting in a range shift. Species Distribution Models (SDMs) can help forecast such range shift responses. For few species, both correlative and mechanistic SDMs were built, but allis shad (Alosa alosa), an endangered anadromous fish species, is one of them. The main purpose of this study was to p...
Location, abundance, and morphology of gill chloride cells were quantified during changes in osmoregulatory physiology accompanying early development in American shad, Alosa sapidissima. During the larval-juvenile transition of shad, gill chloride cells increased 3.5-fold in abundance coincident with gill formation, increased seawater tolerance, and increased Na(+),K(+)-ATPase activity. Chlorid...
