Hubungan Kekerabatan Amfibi (Ordo Anura) di Kecamatan Sibolangit Kabupaten Deli Serdang berdasarkan Morfometrik

Abstract

The research of Amphibians (order Anura) relationship based on morphometrics in Sibolangit, Deli Serdang District, North Sumatera has been conducted in January to July 2015. The purpose of this research was to determine the types and descriptions of Anura species, morphometrics diversity and morphometrics relationship of Anura. Study site was divided into seven different locations settled using Purposive Random Sampling Method. This study was conducted by the active search (Explorative Survey) and direct collection along stream, creeks, ponds, and land around river in the forest in every locations. Samples consisted of at least 5 individuals Anura. Measurements was carried out for 31 morphometric character using a digital caliper. Twenty seven of Anura classifying into six families were recorded from research locations. Statistics analysis of morphometrics descriptive test showed that 14 species diversity coefficients reach over 20%, while 13 other species was below 20%. Anura’s morphometrics relationship for all varieties species depend on body size and morphometrics. The similarity of characters could be caused by food related habitat and food habit. Resemblance species was family indenpendence.
