On the Freshwater Crustaceans of the Central Plateau
ثبت نشده
چکیده
Ever since the first report by the New Zealander, G .lvl. Thomson in 1892, of the occurrence in Tasmania of a number of freshwater crustaceans of ancient lineage, study of these species has been sporadic and it is only within the last decade that zoologists have begun to study the state-wide distribution of these species. Thomson (1892) described the fresh-water shrimp Anaspis tasmaniae~ later called Anaspides tasmaniae. This represented the first description of a living syncarid, a super-order which prior to this time had been known only as marine Carboniferous fossils with a world-wide distribution. Anaspides tasmaniae has a wide distribution in the elevated regions of Tasmania, being found in permanent cool streams and tarns. The life cycle and embryology of Anaspides tasmaniae has been studied by Hickman (1937) while the general ecology of Anaspides has been reviewed by Williams (1965).

Two vessels from different sites of the Iranian Plateau, dating to the late 4th or early 3rd millennium BCE are presented aspalaeotechnological case studies. In the fractures of the vessels’ walls, interfaces left by added clay parts (enhanced inthe two illustrations) are quite recognizable. It is proposed that in both cases potters, in order to construct the bases, usedto make bowls comparable...
متن کاملNew seismic imaging of some tectonic zones in the Iranian Plateau
The Iranian Plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the Zagros and Alborz Mountains) and oceanic plate subduction (e.g. Makransubduction zone). To derive a detailed image of the crust–mantle (Moho) and lithosphere–asthenosphere (LAB) boundaries in some tectonically units of the Iranian Plateau, we used a large number of S receiver functio...
متن کاملThe Qom Plain at the End of Bronze and the Beginning of Iron Age
From the cultural-geographical perspective, the Qom plain is part of the cultural area of the Central Plateau of Iran. Archaeologically, this region had many contacts with other areas of the Central Plateau such as the plains of Kāshān, Sāveh, Qazvin, and Rey. It also had relations with the synchronous centers in the northeast, northwest, central Zāgros, and Khuzestān plain. This is due to it...
متن کاملLow flow frequency analysis by L-moments method (Case study: Iranian Central Plateau River Basin)
Knowledge about low flow statistics is essential for effective water resource planning and management in ungauged orpoorly gauged catchment areas, especially in arid and semi-arid regions such as Iran. We employed a data set of 20 riverflow time-series from the Iranian Central Plateau River Basin, Iran to evaluate the low-flow series using several frequencyanalysis methods and compared the resu...
