Şanlıurfa İlinde Yayılış Gösteren Androctonus crassicauda:Buthidae Türünün Biyo-Ekolojisi Üzerine Araştırmalar

Abstract

Androctonus crassicauda scorpion species lives in nature both as a prey and a predator. So it has venom that can be effective for hunting and protection. It can cause venoming and death by stinging people and animals. It is of great importance to know the ecological characteristics and density of this scorpion species, especially in regions where venoming cases are high. In the present study, Şanlıurfa province, where the scorpion species Androctonus crassicauda is prevalent, was chosen as the research area. 289 samples were collected after field studies in all districts of Şanlıurfa province. Owing to desolated and stony structure, Androctonus crassicauda was observed to be more intensive in Harran district. It was generally found from April to October. The most abundant period of the species is June, July, and August. Considering the seasonal expectation, test results of correlation for a series with non-normal distribution were listed in two options, Kendall'stau_b correlation coefficient and Spearman'srho correlation coefficient. There was a positive correlation of 0,168 (16%) at 1% significance between month and population for the former (Kendall'stau_b) coefficient. A positive correlation of 0,231 (23%) at 1% significance level between month and population for the latter (Spearman'srho) coefficient. In the view of regional expectation, results of correlation test for a non-normal distribution were presented in two options. A negative correlation of 0,099 (9%) was found at 5% significance level between region and population for the former coefficient. There was a negative correlation of 0,128 (12%) at 5% significance level between region and population for the second coefficient. The study revealed a variation between seasons and districts.
