Abstract:
This study aimed to estimate the population density of microhabitat selection and diet composition by Tylototriton uyenoi in the Maesa-Kogma Biosphere Reserve, Chiang Mai Province, Northern Thailand. The population was obtained by the capturerecapture technique including 360 individuals, the total density was 0.089 newts/100 m2 , and the highest density was 12.178 newts/100 m2 in the permanent pond during the breeding season (June to August). The sexual dimorphism was detected with females being larger than the males. Ovipositional areas showed a tendency towards having a dissolved oxygen level of 5.77 mg/L and water temperature of 20.5 °C. Larvae were found under leaf litter in the permanent pond, temporal rainfall pond and slow-flowing stream. The adult sex ratio was 2.25:1. In the breeding season, adult males used a greater variety of habitats than adult females. In the study area, adult newts exhibited a clumped distribution pattern depends on the ponds or slow flowing streams. Our results provide a comparison of fecal pellet prey composition of Tylototriton uyenoi based on an analysis of its fecal pellets. Males of T. uyenoi consumed more diverse preys than females at 53 groups and 14 groups, respectively. The analysis revealed a diverse diet of Arthropoda, Mollusca, Chordata, and conspecific eggs. Partial remnants of plant materials were also found in the pellets. The percentage of frequency of prey occurrence was highest in Formicidae (21.34). Lymnaeidae were obtained the highest percentage in the relative number of prey, The volumetric prey and the Index of Relative Importance (IRI). The Spearman rank coefficient showed a significant positive correlation between prey volume, number and SVL. This study suggested that Tylototriton uyenoi had seasonally population change and a tendency to be non specific predators.
