Morphological, Hemipenial And Venom Electrophoresis Comparisons Of The Levantine Viper, Macrovipera Lebetina (Linnaeus, 1758), From Cyprus And Southern Anatolia, Bayram Göçmen, Hüseyi̇n Arikan, Ahmet Mermer, Bert Langerwerf, Hasan Bahar

Turkish Journal of Zoology

Levantine vipers, Macrovipera lebetina (Linnaeus), from Cyprus and southern Anatolia were investigated comparatively regarding morphology, hemipenes and electrophoresis patterns of venom proteins. There were discernible differences between these compared features of the 2 populations. In the light of these differences, it is concluded that the southern Anatolian population should not be identified as the nominate subspecies M. l. lebetina (Linnaeus), which lives in Cyprus. The study material from northeastern Anatolia did not allow us to make a good comparison between M. lebetina from southern and NE Anatolia.

Testing The Randomness Of The Samples Of Body Size In A Replicated Design In Drosophila Melanogaster Populations From The Eastern Mediterranean, Ergi̇ Deni̇z Özsoy, Ali̇ Ni̇hat Bozcuk

Turkish Journal of Zoology

Strong body size correlates, wing and thorax lengths, of Drosophila melanogaster populations from the Eastern Mediterranean were measured and tested for the presence of autocorrelation, i.e. nonrandom alternation of individual measurements within a sample. The experimental design was a laboratory setup aiming at overall homogeneity in fly culture conditions, which was achieved. A t-test, first proposed by Von Neumann, was performed for the autocorrelation analysis in each population. No significant autocorrelation was detectable, indicating very low bias in the experimental design for nonrandom picking of individuals for measurements. The test is suggested for routine use in studies before any inference …
