Öğe A New Species of Oligoglena Horváth, 1912 (Hemiptera: Cicadidae) from Mediterranean Region of Turkey(Gazi Entomological Research Society, 2023) Mol, AbbasOligoglena sirintaylan sp. n. is defined from Saklikent in Mediterranean Turkey, which are part of the Taurus Mountains. Taurus Mountains are known for their high diversity and endemism rate of both plants and animals. The new species has a characteristic morphology and is distinguished from all other species of the genus Oligoglena Horvath also by its behavioural character. It prefers the subalpine zone and lives in gramineous vegetation.Öğe A new species of Oligoglena Horváth, 1912 (Hemiptera: Cicadidae) from Mediterranean Turkey(Taylor and Francis Ltd., 2020) Mol, AbbasOligoglena gogalaisp. n. is described from Olympos Beydağları Mountains in southern Turkey, which are part of the Taurus Mountains and are known for their high diversity and endemism rate of both plants and animals. The new species has a characteristic morphology and is distinguished from all other species of the genus Oligoglena Horváth also by its song pattern. It prefers the subalpine zone and lives in gramineous vegetation.Öğe A new species of Psorodonotus (Orthoptera, Tettigoniidae) from Anatolia, Turkey(Magnolia Press, 2014) Taylan, Mehmet Sait; Mol, Abbas; Şirin, DenizDescriptions of a new species of Tettigoniinae; Psorodonotus suphani sp. n. from Turkey were given. The relationships between the new species and closest taxa (morphologically and geographically) were evaluated by using morphological characters. Ultimately, some remarkable points of the distribution pattern of the species were presented.Öğe A review of the Anatolian Gomphocerus Thunberg, 1815 (Orthoptera: Acrididae: Gomphocerinae) via morphological and bioacoustics characters: data suggesting a new species, a new subgenus and three new statuses(Zootaxa, 2023) Mol, Abbas; Şirin, Deniz; Taylan, Mehmet Sait; Sevgili, HasanGomphocerus Thunberg, 1815 (Orthoptera, Acrididae, Gomphocerinae) is an interesting genus with clavate antennae, differing from the other genera by the pyriform (pear-shaped) anterior tibiae in the male and being represented by 17 taxa species-subspecies in the Palaearctic region. Anatolian species of this genus have not been adequately studied, and almost all of them are cold tolerance species and live in high mountain meadows. The previous studies indicate that the taxa belonging to Gomphocerus have some taxonomic problems in both Turkey and the Palaearctic region. For this reason, the genus needs taxonomic revision due to its biogeographical, biodiversity, taxonomical and faunistic issues for which morphological and bioacoustics characteristics are to be used. This study was carried out between the years 2015 and 2021 at different altitudes and habitats of the mountains, where Gomphocerus specimens were collected from various localities in Anatolia. Since the species belonging to the genus have distinct morphological differences, the genus is divided into two subgenera: the nominate subgenus and a new subgenus Bolivarianus Mol, subgen. n. In addition, a new species of the nominate subgenus Gomphocerus (Gomphocerus) eyluldenizi Mol, sp.n. is described from Erzurum province (Eastern Anatolia) and when both morphology and bioacoustics characteristics are evaluated, three subspecies of the genus distributed in Anatolia are designated at species level: Gomphocerus (Gomphocerus) turcicus Mistshenko, 1951 stat. n. et sp. rev., Gomphocerus (Bolivarianus) acutus Karabag, 1957 stat. n., and Gomphocerus (Bolivarianus) hemipterus Karabag, 1953 stat. n. Furthermore, a key to the subgenus and species level for Anatolian members of Gomphocerus is provided with original figures, a distributional map and suggestions for conservation status according to IUCN categories are presented.Öğe Bioacoustics characterization of some anatolian endemic and sub-endemic katydids (Orthoptera; Tettigoniidae; Bradyporinae, Phaneropterinae and Tettigoniinae)(MAGNOLIA PRESS, 2019) Taylan, Mehmet Sait; Mol, Abbas; Sevgili, Hasan; Şirin, DenizSeventeen endemic and time sub-endemic species belonging to three subfamilies of Tettigoniidae (Orthoptera: Bradyporinae, Phaneropterinae and Tettigoniinae) were sampled during field trips throughout different regions of Anatolia between 2015 and 2018 (except one taxon). Acoustic parameters of these 20 bush-cricket species affiliated to 12 genera (Apholidoptera, Bradyporus, Decticus, Eupholidoptera, Parapholidoptera, Pezodrymadusa, Pholidoptera, Polysarcus, Psorodonotus, Squamiana, Uvarovistia and Yalvaciana) have been described for the first time in this study. Bioacoustical analysis shows that male calling songs are species-specific for the genera Bradyporus, Parapholidoptera, Pholidoptera, Apholidoptera, Uvarovistia and Psorodonotus. However, there are no distinct differences among species of the genus Pezodrymadusa. Moreover, our additional data on genus Eupholidoptera indicate that there are some different song patterns within the genus. The song description of Uvarovistia zebra presented here is the second bioacoustics data on this genus. The acoustical analyses data support the morpho-species hypothesis of Psorodonotus suphani Taylan & Sirin, 2014, which is known from Suphan Mountain (Bitlis province, Eastern part of Turkey) and reject Kaya & ciplak (2017), which recommended it as synonym to P. caucasicus (Fischer von Waldheim, 1846) (commonly known as a Black Sea Region species).Öğe Bioacoustics review of Anatolian species of the predatory bush-cricket genus Saga (Orthoptera: Tettigoniidae: Saginae) with the description of a new species(Magnolia Press, 2019) Şirin, Deniz; Taylan, Mehmet Sait; Sevgili, Hasan; Mol, AbbasThe genus Saga is a genus of generally large predatory bush-cricket species. It includes 13 taxa in the Palaearctic region. In this research, eight species belonging to Saga (Tettigoniidae, Saginae) were sampled during field studies in different regions of Anatolia of Turkey between 2010 and 2018 (except one specimen). The bioacoustic parameters of these species recorded during the field or in laboratory conditions and the male calling song descriptions, as well as the oscillographic illustrations and distribution maps are given. A new population of Saga found from the South-Eastern Taurus (Hakkari province), which is affiliated to a new species and shows similarity to S. ephippigera, along with the morphological and bioacoustical descriptions of Saga hakkarica sp. n. Sirin & Taylan from Turkey, arc also given. The relationships between the new species and the closest taxa are discussed using morphological and bioacoustical characters. The structural investigations of the male calling songs reveal three different bioacoustic groups affiliated to eight Anatolian Saga species; as (i) Ephippigera group (S. syriaca + (S. ephippigera + Saga hakkarica), (ii) Natoliae group (S. natoliae + (S. beieri + (S. longicaudata + S. puella) and (iii) S. cappadocica.Öğe Characterization of intact chitosan obtained from Bradyporus sp. (Orthoptera, Insecta) and its cytotoxicity on human cell line (HEK293)(Aksaray Üniversitesi, 2024) Umran, Rajaa; Mol, Abbas; Mosa, Amal Umran; Kaya, MuratIntact chitosan film was produced from Bradyporus sp. (Orthoptera, Insecta) and characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), X-ray diffractometer (XRD), Scanning Electron Microscopy (SEM) and elemental analysis. MTT test was performed to determine the cytotoxic effects of chitosan. Chitosan administered at optimal and overdose intervals was applied to HEK293 cells for 24, 48 and 72 hours. In the MTT cytotoxicity test, the IC50 dose of chitosan was 1427 µM at 24 hours, 808.9 µM at 48 hours, and 611.6 µM at 72 hours. Considering all the conducted analyses and cytotoxic experiments, the obtained intact novel chitosan film from the insects could find applications for biotechnological applications.Öğe Comparison of chitin structures isolated from seven Orthoptera species(Elsevier, 2015) Kaya, Murat; Erdoğan, Sevil; Mol, Abbas; Baran, TalatDifferences in the physichochemical properties of the chitin structure of the exoskeleton of seven species from four genera were investigated in this study. The same method was used to isolate the chitin structure of the seven species. The physicochemical properties of the isolated chitins were revealed by ESEM, FTIR, TGA and XRD analyses. The FTIR, TGA and XRD results from the chitin samples were similar. The surface morphologies of the chitins were investigated by ESEM and interesting results were noted. While the surface morphologies of the chitins isolated from two species within the same genus were quite different, the surface morphologies of chitins isolated from species belonging to different genera showed similarity. It was determined that the dry weight chitin contents of the grasshopper species varied between 5.3% and 8.9%. The results of molecular analysis showed that the chitins from seven Orthoptera species (between 5.2 and 6.8 kDa) have low molecular weights. Considering that these invasive and harmful species are killed with insecticides and go to waste in large amounts, this study suggests that they should be collected and evaluated as an alternative chitin source.Öğe Contribution to the knowledge of ensifera (Insecta: Orthoptera) Fauna of Turkey(2016) Mol, Abbas; Taylan, Mehmet Sait; Demir, Eyüp; Şirin, DenizIn this study which contributes to the distribution of species of Ensifera (Insecta: Orthoptera), which are known as bush-crickets, in Turkey, specimens of Tettigoniidae, Gryllidae and Gryllotalpidae (Orthoptera) collected from Turkey and preserved in Aksaray University and Namık Kemal University have been examined. As a result, a total of 117 species-subspecies belonging to 37 genera of the family Tettigoniidae, 6 species belonging to five genera of the family Gryllidae and one species belonging to one genus of the family Gryllotalpidae have been determined from the examined material. Of these species, 67 species are endemic to Turkey, and 12 are harmful to agricultural crops.Öğe Contribution to the knowledge of two endemic species of Anatolian Gomphocerinae Fieber, 1853 (Orthoptera: Acrididae)(Magnolia press, 2015) Mol, Abbas; Taylan, Mehmet Sait; Şirin, DenizThis study focuses on two endemic Anatolian Gomphocerinae Fieber, 1853 species, which are evaluated in terms of nomenclature and taxonomy using biogeographical, morphological, and acoustical data. The original description of Eremippus zeybekoglui is supplemented by the data on new specimens collected from type locality, and the female of this species is described for the first time in this study. Based on the new specimens of Stenobothrus weidneri (Demirsoy, 1977) comb. nov., which were collected at the type locality, the species is transferred from Eremippus Uvarov, 1926 to Stenobothrus Fischer, 1853. Additionally, male calling songs of both species are described for the first time in this study. Also, the biogeography of these species is presented and discussed.Öğe Description of a New Species of the Genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) from Northern Anatolia, Turkey(Gazi Entomological Research Society, 2015) Taylan, Mehmet Sait; Mol, Abbas; Sirin, DenizIn this paper a new species of cave crickets Troglophilus (Orthoptera, Rhaphidophoridae) from northern Anatolia is described as Troglophilus aspegi Taylan and Sirin sp. nov.. Considering the other already recognised nine species in Anatolia, there are now total 10 species of Troglophilus that currently inhabit the caves and epigean habitats of Turkey. The new species is restricted to National Park of Kure Daglari in Bartin province and known only in one locality (Sipahiler cave). Troglophilus aspegi is morphologically distinguishable from the other nine Troglophilus species present in Turkey due to their small size, male tenth tergite, ovipositor shape, reddish-light brown body color. New species differs from the morphologically closest T tatyanae for body color, tenth tergite and epiphallus shape in male, subgenital plate shape in both sexes, length of the appendages and spinulation of the legs. On the other hand, these new data show that geographical distribution of Troglophilus is not only restricted with north eastern Anatolia but also in caves from north western section of Blacksea Region of Turkey.Öğe Differentiations of chitin content and surface morphologies of chitins extracted from male and female grasshopper species(Public Library Science, 2015) Kaya, Murat; Lelesius, Evaldas; Nagrockaite, Radvile; Sargın, İdris; Arslan, Gülşin; Mol, Abbas; Baran, Talat; Can, EsraIn this study, we used Fourier transform infrared spectroscopy (FT-IR), elemental analysis (EA), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), and scanning electron microscopy (SEM) to investigate chitin structure isolated from both sexes of four grasshopper species. FT-IR, EA, XRD, and TGA showed that the chitin was in the alpha form. With respect to gender, two main differences were observed. First, we observed that the quantity of chitin was greater in males than in females and the dry weight of chitin between species ranged from 4.71% to 11.84%. Second, using SEM, we observed that the male chitin surface structure contained 25 - 90nm wide nanofibers and 90 - 250 nm nanopores, while no pores or nanofibers were observed in the chitin surface structure of the majority of females (nanofibers were observed only in M. desertus females). In contrast, the elemental analysis, thermal properties, and crystalline index values for chitin were similar in males and females. Also, we carried out enzymatic digestion of the isolated chitins using commercial chitinase from Streptomyces griseus. We observed that there were no big differences in digestion rate of the chitins from both sexes and commercial chitin. The digestion rates were for grasshoppers' chitins; 88.45-95.48% and for commercial chitin; 94.95%.Öğe Distribution and taxonomy of Gomphocerinae (Orthoptera, Acrididae) species in the anatolian black sea basin and check list of Turkey subfamily fauna(Entomological Research Society, 2013) Mol, Abbas; Zeybekoğlu, ÜnalThis study was carried out especially between 2003 and 2006, at different altitudes and habitats, and 5244 Gomphocerinae specimens were collected in Black Sea Regions to determine subfamily species ranging between 200 meter and 2460 meter in 175 different localities in this area. These specimens were prepared according to standart methods in the laboratory, then researched and compared with present literature, acoustics characteristics, museum specimens determined before, and specimens researched. Finally, 52 species belonging to 17 genera of the Gomphocerinae subfamily along with present literature were indicated in the Black Sea Region. Eight of 52 Gomphocerinae subfamily species were collected for the first time from the Black Sea Region and with previous studies totaly 60 Gomphocerinae subfamily taxon are distributed in this area. In addition to these, Dociostaurus (Kazakia) tartarus has been given a new record for Turkey. Original description name, printed journal, distributions for world, and variations, if existed, were given for every genus and species. By checking over previous studies, check list for Gomphocerinae subfamily fauna of Turkey was prepared, and evaluated in terms of taxonomic, faunistics, and biogeographic terms.Öğe Evaluation of morphological and bioacoustics characteristics of cicadivetta tibialis (Panzer, 1798) (Cicadoidea: Tibicinidae) according to samples collected from the south east mediterranean region of anatolia in Turkey(2017) Mol, AbbasIn this study, in terms of morphological and bioacoustics population of Cicadivetta tibialis from South East Mediterranean Anatolia of Turkey were studied and compared with data from the literature. The morphological features revealed that sample species have not exhibited significant variations according to literature. The sound of the species posses one type of song and this is consist of two phrases: Phrase I and II. The calling song begins in phrase I and continues for minutes (0.84-2.56 s) after the animal sharp to phrase II and continues for about four to nearly eight minutes (5.53-7.47 s), then phrase I repeated. Phrase I evaluated with T1, T2, T3, T4, T5, T6, T7, and T10 parameters. In addition to previous studies, we take into account of T10 which is first T3. All of the data are evaluated by using simple statistical methods and evaluated the spectrum of calling song.Öğe Extraction and characterization of chitin and chitosan with antimicrobial and antioxidant activities from cosmopolitan Orthoptera species (Insecta)(Korean Soc Biotechnology & Bioengineering, 2015) Kaya, Murat; Baran, Talat; Aşan Özüsağlam, Meltem; Çakmak, Yavuz Selim; Tozak, Kabil Özcan; Mol, Abbas; Menteş, Ayfer; Sezen, GöksalThis study examined two gregarious Orthoptera species (Calliptamus barbarus and Oedaleus decorus) as potential sources of chitin. The chitin content of the dry weight of C. barbarus was 20.5 +/- 0.7%, and it was 16.5 +/- 0.7% for O. decorus. Furthermore, the yield of chitosan (70 - 75% deacetylation degree) from the grasshopper species was found to be 74 - 76%, which is close to the yield of commercial preparations obtained from the unused parts of crabs and shrimp. The chitin and chitosan obtained in this way were analyzed using FTIR, TGA, XRD and SEM techniques, and the antimicrobial properties of chitosans obtained from C. barbarus and O. decorus against pathogenic microorganisms of humans and fish were investigated using the disc diffusion and microdilution broth methods. The antimicrobial screening procedures indicated that the chitosan showed significant antimicrobial activity against all of the tested pathogenic microorganisms. The MBC or MFC values were determined to be 0.16 - 2.50 mg/mL. The IC50 values for the chitins obtained from C. barbarus and O. decorus were 10.68 +/- 0.27 and 10.91 +/- 0.96 mg/mL, respectively, which were greater than the value for butylated hydroxytoluene (BHT): 0.04 +/- 0.01 mg/mL. These results suggest that these two species, which are currently considered to be pests because of over-breeding, are potentially alternative sources of chitin and chitosan, which are used in the food/feed industry for their antimicrobial and antioxidant properties.Öğe Extraction of high thermally stable and nanofibrous chitin from Cicada (Cicadoidea)(Wiley, 2018) Mol, Abbas; Kaya, Murat; Mujtaba, Muhammad; Akyüz, BaharDue to the increasing interest in natural biopolymers including chitin, the exploitation of economic and easily accessible chitin sources with good physicochemical properties is nowadays required. In view of this fact, in the current study chitin was extracted and physicochemically characterized from six Cicadas (Hemiptera: Homoptera: Cicadoidea) species collected from Mediterranean region of Turkey (2014-15). Chitin was extracted using a classic extraction method that includes acid and base treatment. TGA results revealed a remarkable increase (410-412 degrees C) for all the six Cicada species compared to other chitin samples extracted from various sources. For all of the six selected species the chitin contents on the dry basis were determined as 6.7% for Cicadatra atra, 5.51% for C. hyalina, 8.84% for C. platyptera, 4.97% for Cicada lodosi, 6.49% for C. mordoganensis, and 5.88% for Cicadetta tibialis. The surface morphology of chitin isolates from Cicada species was observed to consist of nanofibers and nanopores.Öğe First song descriptions of some Anatolian species of Tettigoniidae Krauss, 1902 (Orthoptera, Ensifera)(Pensoft Publications, 2014) Şirin, Deniz; Taylan, Mehmet Sait; Mol, AbbasFourteen endemic and two sub-endemic species belonging to three subfamilies of Tettigoniidae (Tettigoniinae, Bradyporinae and Saginae) were sampled during field trips throughout the different ranges of Anatolia between the years of 2004 and 2013. Acoustic parameters of these 16 species affiliated to 8 genera (Anterastes, Apholidoptera, Gampsocleis, Parapholidoptera, Pezodrymadusa, Psorodonotus, Bradyporus and Saga) have been described for the first time in this study. Acoustical analysis showed that song characters are species-specific in the genera Saga and Psorodonotus. On the other hand, we could not find big differences among species of the genus Pezodrymadusa and Parapholidoptera castaneoviridis species-group.Öğe Morphological and acoustic analysis of cicada linnaeus, 1758 species in Turkey: (Hemiptera: Cicadomorpha: Cicadidae(MAX KASPAREK VERLAG, 2011) Zeybeko?lu, Ünal; Mol, Abbas; Karavin, MuratThe morphological characters and the male calling songs of four species of Cicada occurring in Turkey, namely Cicada lodosi Boulard, 1979, C. mordoganensis Boulard, 1979, C. orni (Linnaeus, 1758) and C. pennagna (Haupt, 1917), were compared. Figures of the fore body and genitalia, and song oscillograms, are given for each species. Cicada mordoganensis, C. orni and C. permagna are very similar but they clearly differ from C. lodosi. C. permagna was determined as a valid species.Öğe Morphological and acoustic characters of Cicadatra platyptera Fieber, 1876(PENSOFT PUBL, 2013) Mol, Abbas; Zeybekoğlu, Ünal; Akyürek, BaşakAcoustic and morphological characters are very important to distinguish species of Cicadidae. In this study, the morphological and acoustic characters of Cicadatra platyptera Fieber, 1876 (Hemiptera, Cicadidae) collected from Turkey were analysed. The external morphological structures of two species were drawn and photographs of some specimens were taken. We evaluated taxonomically important morphological characters such as body shape, colors, patterns, structure, and genital structure. We evaluated measurements of external morphological structures and acoustics characters of C. platyptera from Turkey, partly with statistical analyses. Morphological characters were compared and differentiated from the closely related species, C. atra. The distribution in Turkey including previous records and the material examined were shown on a map, and the distribution in Palearctic Region was given.Öğe Myrmeleotettix Bolivar (Orthoptera, Gomphocerinae) in Anatolia on the basis of morphological and behavioural characters: Data suggest a new species from southern end of the Anatolian refugium(2011) Şirin, Deniz; Mol, Abbas; Çıplak, BattalMyrmeleotettix Bolivar, 1914 (Orthoptera, Acrididae, Gomphocerinae) is a genus represented by nine species in the whole Palaearctic. It is poorly known in Anatolia except some records of M. maculatus. As for the other glacial refugia, cold preferring members of this genus are discontinuously distributed on high altitudes in Anatolia. Additionally, morphology is not sufficiently useful in taxonomy of gomphocerinae members for those producing a complicate courtship song. Thus an accurate taxonomy requires extensive materials and different character sources. In this study, the taxonomy of Anatolian Myrmeleotettix is reexamined on the basis of qualitative and morphometric morphology, and male calling and courtship songs. Song and morphology both suggest the existence of two species in Anatolia. The first is M. maculatus (Thunberg) which is distributed along the northern one-third of Anatolia in addition to other parts of West Palaearctic. The second is a new species, Myrmeleotettix ethicus sp. n. possibly endemic to the southwest corner of Anatolia. The new species can be easily distinguished from the most similar species M. maculatus by morphology as well as by song characters. The conclusions are: (i) similarities in courtship and calling songs of these two species may indicate that they are sister species (ii) from habitat preference and distribution patterns it can be inferred that they diverged following a cold period and the new species is a remnant of ancestral population in southern Taurus, and (iii) the new species is a range restricted, vulnerable species as is the case for many other taxa present in the Mediterranean Taurus biodiversity hotspot.
