Diversity of Morphometric Characteristics of Knipowitschia caucasica (Berg, 1916) in Gomishan Wetland and Gorgan Bay (Southern Basin of the Caspian Sea)

This study was carried out with the aim of investigating the possibility of separation of Caucasian faeces with the aid of grapefruit traits (Berg, 1916) Knipowitschia caucasica between two areas of Gomishan wetland and Gorgan Bay in the spring of 1395. In this study 120 samples of this species were studied. In this study, the method of analysis of the main components of the possibility of separating the two reserves was studied. The properties studied were separately compared to each other. The traits were standardized before being used by Bagam method. The KMO coefficient was 0.81, indicating the suitability of the decomposition method to be the principal components for examining the possibility of separating the reserves. The output of the experimental model to the main components indicated that there were four factors with special values ​​greater than one for morphometric traits and six factors for relative morphometric characteristics. The results of this study showed that the Caucasian gastropods in these two regions can be divided into two separate reserves despite the presence of partial mixing.
