Hair Morphology Examination of Badger Meles Meles (L., 1758) in Turkey By Using Light And Scanning Electron Microscopes

In this study, the hairs of the badger (Meles meles) in the collection and various museums were examined and was tried to determine whether there were variations. For the morphological analysis of the guard hair samples taken from the middle part of the ridge, the guard hairs were examined by both light microscopy and scanning electron microscopy (SEM). The root of the guard hairs on the back and sides was dirty white, the body was brownish black and the tip was white. The length of the hairs on the back and sides was determined to be about 75 mm. It was determined that 21 of the samples had summer fur, the dorsal part had brown and transition tones had dark brown hairs, and 4 had winter fur, the dorsal part had grayish brown hairs and the ventral part had blackish light brown hairs. In addition, winter fur was found to be covered more frequently and with long guard hair

Investigation Of Morphological Structure Of Yenom Glandsin Female Agelena Labyrinthica

Bu çalışmada, huni örümceği Agelena labyrinthica'nm zehir bezinin morfoloj ik yapısı ışık ve taramalı elektron mikroskopta (SEM) incelenmiştir. Zehir bezinin dıştan içe doğru kalın bir kas tabakası, bazal lamina ve salgı epitel hücrelerinden meydana geldiği görülmüştür. Çinili kas tabakasının sarmal şekilde bezin etrafını kuşattığı ve iç kısımdaki bazal laminaya kadar uzandığı tespit edilmiştir. Kas tabakası ile salgı hücrelerini birbirinden ayıran bazal laminanm altında, zehir üretimiyle görevli salgı epitel hücrelerinin yer aldığı ve bu hücrelerin büyük çekirdekli olup sitoplazmalarmm ise çok sayıda salgı granülü ile dolu olduğu saptanmıştırIn this study, the venom gland of the funnel spider Agelena labyrinthica was investigated in relation to morphological structure using light and scanning electron microscope (SEM). From outside to inside the venom gland was observed to be composed of a thick muscle layer, basal lamina and glandular epithelial cells. It is determined that the striated muscle layer spirally covers the gland and lies up to basal lamina in the gland. Under basal lamina separating muscle tissue and glandular cells, venom producing glandular epithelial cells which have large nucleus in addition to their cytoplasm containing many secretion granules was determine

Mitochondrial DNA control region variability of wild boar Susscrofa with various external phenotypes in Turkey

The wild boar (Sus scrofa L.) is distributed across most parts of Turkey, a major biogeographic crossroads connecting Southwest Asia and Southeast Europe. However, no information on genetic diversity and population structure of this species in Turkey is available. In this study, we report on mtDNA sequence variability and phylogenetic relationships among wild boars with variable external phenotypes from both its European (Turkish Thrace) and Asian (Anatolia) distributions in Turkey. Phylogenetic analyses of mtDNA D-loop sequences (413 bp) of 53 newly sequenced wild boars from different localities in Turkey and 432 wild boar sequences from various geographic origins downloaded from GenBank were performed to particularly compare the phylogeographic position of wild boars from the European part of the Turkish range with that of specimens from Anatolia and to explore a possible phylogeographic substructuring in Anatolia. Relatively high genetic diversity was found in the Turkish samples, with a total of 17 haplotypes. Phylogenetic analyses revealed partitioning of the currently found Turkish haplotypes into two haplogroups, which were, however, only partially concordant with the geographic origins of samples (central and southwestern Anatolia vs. Turkish Thrace and northeastern and southeastern Anatolia). A median-joining network grouped most Turkish haplotypes with those previously reported from the Near East, whereas the remaining two haplotypes were included in the European 1 haplogroup. The combined phylogenetic analysis of the currently obtained sequences and all sequences retrieved from GenBank supported the earlier findings of four major haplogroups. The present study will serve as a baseline for more comprehensive studies to understand phylogenetic relationships of wild boars in Turkey and the Near East

Zur Schädlingsvertilgung einiger Singvogelarten in einem Schwarzkiefern/Eichen-Mischbestand im Beynamer Wald bei Ankara*

erdogan, ali/0000-0001-5970-6030WOS: 000177359300003Analysis of nestling food in four species of Parus and one species of Ficedula using the 'Halsringmethode' showed a high quota of adults and caterpillars of the important forest pests: Tortrix viridana, Euproctis chrysorrhoea, Diprion pini, and Lymantria dispar . These four major pest species amounted in the nestling food of Parus major to 50 %, P. coeruleus to 52.6 %, P. ater to 40.9 %, and Ficedula hypoleuca to 30.2 %
