Correspondence: A method for determining total nitrogen...

The digestion method using a small proportion of a strong oxidizing agent perchloric acid seems to have been taken from a ’continuous flow method’, which was not designed for discrete digestion and analysis. There is considerable evidence that satisfactory digestion ofeven tMrly refractory substances can be achieved without the use of perchloric acid (1) and it is now usually recommended that p...

The knowledge of the evolution of the human genome is strictly dependent on the availability of appropriate genetic markers and their relative coverage of genetic variation which refine the phylogenetic reconstruction. While autosomal markers are particularly valuable for recognizing correspondence between genetic and geographic distances, markers on mitochondrial DNA (mtDNA) or Non Recombining...

Recently, Frayer et al. (2010) (this journal,...
