Abstract

Maleo bird (Macrocephalon maleo) is the one of protected bird’s species and originated from Sulawesi island of Indonesia. This study was carried out to obtain the growth curve of body weight (BW) in mixed-sex Maleo birds from hatching to yearling ages. The growth curve in this study was calculated with non-linear regression of Logistic (L) and Gompertz (G) models using CurveExprt 1.4. computer program. The primary data in this study was cited from previous study through a literature study. Research showed that the asymptotic weight (A) in birds was 1825.34 g (L) and 3429.23 g (G). The weight of inflection (Wi) in studied birds were 912.67 g (L) and 1260.75 g (G). The time of inflection (ti) in birds was 8.51 months (L) and 11.00 months (G). The maximum growth rate in birds was 159.72 g/month (L) and 151.29 g/month (G). The coefficient of determination (R2) in both models included of very high category (0.80<R2<1.00) but the lower of standard error (SE) value showed in L model. It can be concluded that the non-linear regression of Logistic model can be used as BW predictors in mixed-sex Maleo birds.

Abstract

Water Monitor (WM) lizard (Varanus salvator) are one of Varanidae family lizard that widely spread at Southeast Asia belonging to Peninsular Malaysia. This research was conducted to observe the halotype diversity in partial mitochondrial Cytochrome b (Cytb) gene (344 bp) of WM lizards at Peninsular Malaysia. A total of seventeen (17) Cytb sequences of WM lizard were collected from NCBI database. Research showed that five (5) haplotypes of Cytb gene were observed in the observed sequences. About 71% of WM lizards from Peninsular Malaysia were classified into Haplotype 3 (Hap.3). Hence, this haplotype was classified as the common ancestral of WM lizard at Penensular Malaysia. The Neutrality test revealed that low allelic frequency in WM lizard can be caused by species expansion. In conclusion, the WM lizards at Peninsular Malaysia consisted of two (2) clades of Clade A (Hap.1 and Hap.2) and Clade B (Hap.3, Hap.4 and Hap.5).
