Abstract
Abstract: Diet and trophic niche of Teratoscincus roborowskii was
analyzed by pellets analysis technique. A total of 263 pellets of
Teratoscincus roborowskii were collected from the Turpan Botanic Garden
in Turpan City from July to Octobor, 2016, . Food composition and
proportion of Teratoscincus roborowskii were identified by comparative
analysis. The number of food components in the fecal samples was
identified, and the numeric frequency, biomass ratio and frequency of
occurrence of each component were counted and then the monthly
Shannon-wiener diversity index, Shannon evenness index and diet niche
width were analyzed. The results show that the Teratoscincus roborowskii
mainly feed on insects and caper fruit in the Turpan Botanic Garden.
Insects are the most common food for the Teratoscincus roborowskii, the
frequency of occurrence which in each month is the largest; caper fruit
was the most food intake in July and August, and that of insects is the
most one on September and October. There are some differences in the
composition of food in different months, which may be related to changes
of food availability. The results of the feeding habit analysis show
that the Teratoscincus roborowskii may play an active role in the
dispersal of caper seed.
