Habitat segregation in two congeneric hawk-eagles (Spizaetus bartelsi and S. cirrhatus) in Java, Indonesia

The Javan hawk-eagle: misconceptions about rareness and threat

The Javan hawk-eagle (Spizaetus bartelsi) is a threatened raptor endemic to the densely populated island of Java. Historically very little is known about its biology. Recent surveys showed that the population size has been underestimated in the past. The breeding population is estimated to be 137±188 pairs with a total of 600±900 birds and con®rmed presence in 22 discrete forest blocks througho...

Species or subspecies? The dilemma of taxonomic ranking of some South-East Asian hawk-eagles (genus Spizaetus )

A molecular phylogeny of the Spizaetus cirrhatus complex is presented in this study, based on two sections of the mitochondrial genome: partial sequences of the cytochrome b gene and of the control region (CR). The topologies derived from the two sequences are in agreement. Within S. cirrhatus distances are rather low (0–1.5% in cytochrome b). Among the cirrhatus subspecies the island taxa flor...

Genetic Variation of Cytochrome b Gene in Three Local Goat Breeds in Central Java of Indonesia

This study was conducted to elucidate the genetic diversity and phylogenic relationship of three local goat breeds in Central Java of Indonesia based on the cytochrome b (cyt b) gene sequence. Blood samples of 19, 15 and 12 heads of Kacang, Kejobong and Ettawa Grade breeds, respectively, were used as materials of the study. The multiple alignment of cyt b gene was conducted by comparing under s...
