We used a population genetic approach to quantify major population subdivisions and patterns of migration within a broadly distributed Indo-Pacific parrotfish. We genotyped 15 microsatellite loci in Scarus rubroviolaceus collected from 20 localities between Africa and the Americas. A STRUCTURE model indicates the presence of four major populations: Eastern Pacific, Hawaii, Central-West Pacific ...
the japanese threadfin bream, nemipterus japonicus, the most abundant and crucially economic nemipterus species is widespread throughout the indo-west pacific. the species has been studied widely for various aspects but genetic studies are scanty. this preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of n. japonicus...
Aims & Backgrounds: Drought is a natural feature of an area and in every region that occurs, it leads to economic, social and environmental losses. In this research, the Teleconnection patterns in drought occurrence in Qarh Qom basin has been investigated. Methodology: In this regard, precipitation data of 30 rain gauge and synoptic stations as well as data on 32 numerical indexes of teleconnec...

The goliath grouper Epinephelus itajara (Epinephelidae) is an exceptionally large marine fish that inhabits sub-tropical and tropical waters of the Americas and western Africa. Due to a lack of readily observable morphological variation in specimens across its range, the goliath grouper has been regarded as a single species. We tested the hypothesis that Pacific and West Atlantic populations co...
Species of the limpet genus Siphonaria (Gastropoda: Euthyneura) are commonly found in the rocky intertidal, worldwide, except in the Arctic. In total, 205 species-group names are available and not permanently invalid. However, estimating the actual species diversity of Siphonaria has remained challenging, mainly because past authors have interpreted differently the variation of shell characters...
Southern Oscillation Index (SOI) and Sea Surface Temperature (SST) patterns affect rainfall in many parts of the world. This study aimed to investigate the relationship between monthly and seasonal rainfall of Iran versus SOI and Pacific and Indian sea surface temperature. Monthly rainfall data, from 50 synoptic stations with at least 30 years of records up to the end of 2007, were used. Monthl...
Using satellite cloud data from the Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) and collocated precipitation rates from the Advanced Microwave Scanning Radiometer (AMSR), it is shown that rain rate is closely related to the amount of very thick high cloud, which is a better proxy for precipitation than outgoing longwave radiation (OLR). It is also shown that thin high cloud, whic...
We investigated the effects of large-scale orography on the tropical coupled atmosphere-ocean system over the Indian and Pacific Oceans in northern summer, using the Meteorological Research Institute coupled atmosphere-ocean General Circulation Model (GCM). Six different experiments were conducted with mountain heights of 100%, 80%, 60%, 40%, 20%, and 0% of the standard mountain height. The res...
Oceanic emissions of halogenated very short-lived substances (VSLS) are expected to contribute significantly to the stratospheric halogen loading and therefore to ozone depletion. The amount of VSLS transported into the stratosphere is estimated based on in-situ observations around the tropical tropopause layer (TTL) and on modeling studies which mostly use prescribed global emission scenarios ...
