Reproductive biology of sea cucumber (Holothuriascabra) in north coast of Qeshm Island, Persian Gulf
Sea cucumber species are commercially important in the world. This study explored the reproductive biology of sand fish sea Cucumber in Qeshmisalnd in the Persain Gulf for a year, from December 2012 to November 2013. The macroscopic study intended to examine the features such as gonad color, gonad weight, their length and diameter, and specify the spawning season. Microscopic examinations inclu...
The effective patterns and mechanisms of synoptic systems during the wet and dry spells in Midwest of Iran(MWI) analyzed and discussed on seasonal scales from 1974 to 2003. Synoptic Analysis is based on synoptic chartson Sea Level Pressure (SLP), 850 and 500 Hpa levels. The results of synoptic analysis show that dry spells in MWIare mostly corresponded to Azores High (AZH) intensifying and its ...

Afforestation has been one of the most effective measures to compensate for mangrove ecosystem loss across the world and requires a detailed understanding of all contributing hydrological and physico-chemical factors affecting their growth. In this study, the Maxent habitat suitability model was employed to identify suitable mangrove habitats in the Hara Roud-e Gaz Protected Area. Presence da...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
We planed to conduct a “mowing the lawn” type of multibeam bathymetry and backscatter survey of the Florida Middle Ground HAPC (Habitat Area of Particular Concern; Figure 1) and to collect some ground truth data. The survey was to augment the existing coverage in the area from a previous USF cruise and will entail for the most part very long lines compared to the number of turns (Figure 1). The...
The scientific problems of the assessing of the impact of environmental factors on human health and the explanation of health-improving activities today are the priorities of state environmental policy in all developed countries. Environment and human health are the actual problems, which currently have the attention of the Republic of Kazakhstan. One of the crisis regions of Kazakhstan is reco...
The Kelkit Valley is geographically a transitional zone between the Middle Black Sea and Inner Anatolia regions in Turkey. Two new species of Macrochelidae are described from this area--Longicheles ozkani sp. nov. and Longicheles ayyildizi sp. nov. Longicheles lagrecai (Valle, 1963) is recorded for the Turkish fauna and redescribed on the basis of specimens collected from the Valley. A world-wi...
1. introduction variability and changes in precipitation amounts, including extreme precipitation and droughts, trigger relevant societal and environmental impacts. atmospheric circulation strongly determines precipitation variability over southern half of iran. the influence of prevalent synoptic situations on the distribution of precipitation amounts needs to be understood, as well as their f...
