The Ecofaunistics of Scorpions in Gonabad

Ofogh-e-Danesh …, 2010

Abstract Background and Aim: The scorpion stinging is one of the most important health problems in the world and poisoning by scorpion’s poison is considered a matter of some medical urgency. Therefore, it is necessary to become acquainted with the ecology and biology of scorpion’s species in any area. Few studies have been carried out regarding the scorpion’s biology; and laboratory studies are not comparable with the natural condition of this arthropod. The purpose of the present study is to determine the scorpions’ biology and ecology in Gonabad city in order to present some preventive health and medical strategies against scorpionstinging. Material and Methods: This study is a kind of descriptive and applied one which was conducted based on random cluster sampling method in Gonabad, Iran. In so doing, 218 scorpions caught from April to August (2008) were grouped based on the hunting area and then transferred to the laboratory in separate bottles containing alcohol 70%. And finally, they were identified using the identification guide for Iranian scorpions. Results: In general, 218 scorpion samples were caught from different zoogeographical areas in Gonabad. They were three species of Odontobuthus dorie, Androctonus crassicaud, Mesobothus eupeus from Buthidae family. The greatest number of the collected scorpions was from the desert areas with clay and sand and they belonged to Odontobuthus dorie (61%); and the fewest number belonged to Androctonus crassicauda (10%). However, the most abundant scorpions in both urban and rural areas belonged to Mesobothus eupeus (29%) and they had their most period of activity in June. Conclusion: Considering the different species of the hunted scorpions, it is necessary not only to inform the public but also to educate them on how to take preventive actions against scorpion stinging.

Ferruginous Oolitic Limestone in Shishtu Formation (Late Devonian) and the Role of Microbial Activities in Their Formation

2009

Ferruginous shallow marine limestones of Late Devonian age-mainly Famennian-are widely distributed across central and eastern Iran. The iron, almost hematite, is concentrated in oolitic and skeletal grainstones, skeletal packstones and rarely in lime-mudstones. Hematite occurred as clay coatings on various allochems (ooids, bioclasts and intraclasts), and also as finely dispersed clays within micritic beds. Most grains are concentrically laminated with alternations on ferruginous clays and micro-laminae suggesting that the clays were syndepositionally formed on grain surfaces. The ferruginous beds are commonly associated with ooides and oncoides. The planar to wavy and sometimes discontinuous laminae with individual thickness of 2 to 5 m resemble oncolitic microbialites. The microbial tubules from laminae show several concentric layer of stepwise growth around a core. Micro-morphological and mineralogical characteristics suggest biogenic factors are essential for the formation of ferruginous grains.

Synopsis of Biodiversity and Distrebution of Macrophytes Along the Suez Canal in Time and Space

2015

The large project of the new Suez Canal ,started by August 2014 will change many aspects in its characteristics especially the biological .We need to establish a picture of the existing fauna and flora , in order to build a base line on which we can follow any possible changes . We could have a final figure of the Suez Canal benthic flora as a conclusion of 30 years investigations on the Marine flora of the Suez Canal region . Discussion and analysis with the previous works on these major benthic primary producers illustrates a good speculation and best understanding of the development of the flora in time and space .

First record of the genus and species, Syrphophilus bizonarius from Iran

2014

In order to determine the parasitoid insects (Hymenoptera) associating with cabbage fields, a sampling was perfomed at southern part of Tehran in 2011. Five species of parasitoid wasps belonging to three families including, Oomyzus sokolowskii (Kurdjumov, 1912) (Eulophidae), Pteromalus sp. (Pteromalidae), Cotesia plutellae (Kurdjumov, 1912) (Braconidae), Diadegma anurum (Thomson, 1877) and Syrphophilus bizonarius (Gravenhorst, 1829) (Ichenumonidae) were collected and identified. S. bizonarius (Ichneumonidae: Diplazontinae) representing a new genus and species record for the fauna of Iran.
