Flea beetles (Coleoptera: Chrysomelidae: Alticinae) collected by malaise trap method in Gölcük Natural Park (Isparta, Turkey), with a new record for Turkish fauna

This study is based on Alticinae (Coleoptera: Chrysomelidae) material collected by Malaise trapping which is different from other standardized collecting methods. A total of 19 flea beetle species belonging to 6 genera were collected from Gölcük Natural Park, Isparta (Turkey) during 2009. The species are listed in a table together with distributional data in Turkey. Among them, Longitarsus curtus (Allard, 1860) is recorded for the first time in Turkey. L. monticola Kutschera, 1863 and L. curtus are recently separated synonyms and thus all data referring to the distribution of both species are currently important. Hence, the zoogeographical distribution of the new record is reviewed with some remarks; habitus and genitalia are illustrated

A study on heavy metal concentration in Izmit gulf

Water samples taken from thirteen different stations and from three streams in İzmit Gulf where the pollution is very high have been investigated with Atomic Absorption Spectrometre for heavy metal (Cu, Fe, Pb, Cd, As and Hg) concentrations. From the data obtained, Hereke has been observed to have the highest heavy metal concentration in the area, but Gölcük is safe. Despite this, each station contains various heavy metal concentration levels. At the end of this study, it has been determined that heavy metal concentration is higher in deep waters than the surface of the water.Water samples taken from thirteen different stations and from three streams in İzmit Gulf where the pollution is very high have been investigated with Atomic Absorption Spectrometre for heavy metal (Cu, Fe, Pb, Cd, As and Hg) concentrations.

Vibrations due to Dynamic Compaction

Ground vibrations due to dynamic compaction (DC), at a harbor site were measured to investigate whether the magnitude of vibrations were unacceptably strong to cause any damage to or increase existing damage on the surrounding structures experienced August 17, 1999 Kocaeli, Gölcük earthquake (M~7.4). The site is located in city of Kocaeli at the seaside of The Port of Derince. It was a reclaimed land formed with Hereke limestones. The measured data included vibrations induced by the tamping energy of DC both at the vicinity of nearby structures and within the DC site. The site was surrounded by a shallow isolation trench all along the land sides. This paper presents the case and the characteristics of vibration such as peak values of the records, Fourier spectrum and amplitude attenuations over distance. The predominant frequencies and amplitude of vibrations were compared to the related code limits to estimate the effect of vibrations on the existing structures

The August 17, 1999 Izmit, Turkey, earthquake: slip distribution from dislocation modeling of DInSAR and surface offset

We show the results of application of Differential SAR Interferometry to the MW 7.4, August 17, 1999, Izmit earthquake, Western Turkey. The differential interferogram is obtained using an interferometric ERS2 ascending pair with a time interval of 35 days (August 13th - September 17th). The fringe pattern clearly defines the coseismic displacement field extended in an area of about 100 km N-S and 120 km E-W. The analysis of the interferogram shows the right-lateral strike-slip movement on the activated section of the North Anatolian fault system. The maximum SAR-detected displacement ranges between 117.6 cm and 134.4 cm in the proximity of Gölcük. We invert SAR data for uniform dislocation on a single fault plane using a Montecarlo procedure, with the aim of testing a large set of a priori possible asperity distributions on the fault. We then use a forward modeling approach to evaluate the slip variability for the dislocation using additional constraints as surface offsets and seismicity distribution: in this case we allow unit cells to undergo different values of slip in order to refine the initial dislocation model. Misfits between SAR data and modeled slant range displacements are generally low for all our models (~ 12 cm). Our results indicate that slip is concentrated in the central-western part of the fault, in the upper 10-15 km, tapering to the fault tips. For the Izmit case, we note that a well constrained fault model can be obtained only integrating DInSAR data with additional observations. This is mainly due to an undersampling of the displacement field by DInSAR, caused by decorrelation and lack of image data

Hymenoptera of Nide province: Studies on Sphecidae fauna

The present study is based on 1240 specimens obtained from the field studies in the vicinity of Ankara province in Turkey between the years of 2006 - 2008. In fauna studies carried out in Nide province between May 2006 - October 2008, the specimens of Sphecinae Latreille, 1802, PempheredoninaeDahlbom, 1835, Astatianae Lepeletier, 1845, Crabroninae Latreille, 1802, Bembicinae Latreille, 1802, Philanthinae Latreille, 1802 sub-families belonging to Sphecidae family were collected. 52 of the collected specimens are new records for Nide province. Astata pontica Pulawski, 1958 species is anew record for Turkey

First contribution on distribution, abundance, and species richness of blowfly species (Diptera) of Isparta Province with five new records for the Turkish fauna

Despite the increasing importance of species richness of blowfly fauna and their environmental, medical, and agricultural importance in the world they are poorly studied in Turkey. This study was carried out in 2014 and 2015 to determine the distribution, abundance, and species richness of blowfly species in Isparta Province of Turkey. A total of 15 species (10 from Calliphoridae, 4 from Polleniidae, and 1 from Rhiniidae) were identified from 13 different localities. The adult specimens were obtained from areas of organic and decayed organic matters, waste and dumpsite, surrounding waste water deposits, and flowering plants. While all the species were new for Isparta, Bellardia tatrica (Enderlein, 1933), Calliphora subalpina (Ringdahl, 1931), Lucilia silvarium (Meigen, 1826), Melinda gentilis (Robineau-Desvoidy, 1830) and Pollenia griseotomentosa (Jacentkovsky, 1944) were determined as new records for the Turkish fauna. According to the study results, the highest levels of blowfly species richness will be mainly focused in the eastern part of Isparta Province. Chrysomya albiceps and Lucilia sericata were determined as the most common species in the study.Peer reviewe

Sedimentary record of coseismic subsidence in Hersek coastal lagoon (Izmit Bay, Turkey) and the late Holocene activity of the North Anatolian Fault

This research was funded by the European Union in the framework of the REL.I.E.F. (Reliable Information on Earthquake Faulting) project (EVG1‐CT‐2002‐00069). Copyright @ 2011 American Geophysical Union.The late Holocene activity of a restraining bend of the northern strand of the North Anatolian Fault in Izmit Bay was investigated by a sedimentological, geochemical, and paleoecological analysis of sediment cores from Hersek coastal lagoon, NW Turkey. The sediment cores show a succession of sedimentary sequences composed of three units separated by gradual transitions. The first unit is composed of a thin layer of shell debris-rich sediment in abrupt contact with the underlying organic-rich deposits. This unit is over-lain by a thick foraminifera-rich mud deposit, and the sequences are capped by an organic-rich mud unit. These sequences are interpreted as silting up, shallowing upward deposits, typical of a lagoon becoming isolated from the sea. We suggest that they represent the sedimentary signature of coseismic subsidence, which was caused by reverse slip at the Hersek bend, and tsunamis in Izmit Bay. Our radiocarbon-dated paleoseismological record indicates (1) the atypical collapse of the hanging wall during the 740 earthquake and (2) subsidence of the footwall during the 987, 1509, and 1719 earthquakes. This study contributes to the understanding of the dynamics of restraining bends, and it highlights the potential of coastal sediments for reconstructing past earthquakes and tsunamis in regions dominated by strike-slip deformations.This article is available through the Brunel Open Access Publishing Fun

A hybrid approach to apply dematel in a multi-criteria setting

The DEMATEL method has been applied in the Decision Sciences in several studies. However, one has not been able to apply DEMATEL directly to a multi-criteria matrix formed by a set of alternatives and a set of criteria yet. In order to approach this, we propose a novel way to apply DEMATEL to a multi-criteria matrix for ranking a set of alternatives according to their performances in a set of criteria. For accomplishing this, we consider the set of alternatives in a classical multi-criteria problem as the set of components used in a usual DEMATEL application. To set up the influence degree among studied components, we used the preference index of PROMÉTHÉE II. Such preference index takes into consideration the performances of alternatives on all criteria to establish each influence degree. Thereby, we denote the influence degree by preference degree. This new approach is applied to a case study and results are compared against those of three multi-criteria methods. It is then possible to note small, understandable differences among the rankings. This hybrid approach has therefore shown to be theoretically sound and feasible to be used in the practice of Multi-Criteria Decision Analysis

Human dimension of the 1999 Marmara earthquakes in Turkey: Traumatic menthal health effects and consequences

By definition, disasters are natural phenomena that occur unexpectedly. Moreover, throughout the ages, human communities have experienced numerous disasters and the expectation is that there will be as many more in the coming years. On a daily basis, there are reports of earthquakes, hurricanes, and flood disaster news on TVs, radios, and other news media. Therefore, it is important to understand the effects of natural disasters on individuals as well as on community-based institutions. For these reasons, in particular, the purpose of this study is to explore, understand and analyze the notorious 1999 Marmara Earthquake on people’s daily lives and social institutions. It is expected that peoples and countries within the earthquake zone can learn lessons from this Turkish Earthquake and draw some conclusions for the sake of their people’s mental health as well as help protect their social institutions in the event of such hard times
