The Bovini tribe contains domestic and wild cattle-like species, several of which are cross-fertile. We present a completely resolved Y-chromosomal phylogeny, which is better in agreement with autosomal phylogeny, morphological data, cross-fertility and estimates of divergence times than mitochondrial data. The tree links Bos grunniens (yak) to Bison, so the commonly accepted Bos genus is not monophyletic. Therefore, we advocate the term Poephagus as designation of yak. This work illustrates the resolving power of Y-chromosomal variation for cladistic studies of closely related species.

Numbers of the Asian elephants (Elephas maximus) population are declining due to poaching, human-elephant conflicts, capture of wild calves for tourism and export and habitat destruction, which also may cause inbreeding in fragmented populations. In order to contribute to a reversal of this trend, we have developed an identification and parentage test by evaluation and selection of markers from 43 microsatellite loci that have been previously described for Asian or African elephants. Testing these markers on a panel of 169 Asian elephants comprising the 23 mother-offspring, 13 father-offspring and 13 parents-offspring pairs yielded 26 polymorphic markers. However, only 14 of these were found to be suitable for an analysis of molecular diversity, 12 of which will be implemented for an identification and parentage test to control the capture of wild calves in Thailand and neighboring countries.
