■ Abstract The number, size, and scope of phylogenetic analyses using molecular data has increased steadily in recent years. This has simultaneously led to a dramatic improvement in our understanding of phylogenetic relationships and a better appreciation for an array of methodological problems that continue to hinder progress in phylogenetic studies of certain data sets and/or particular parts...

conclusions the widespread distribution of l. major parasites in human suggests not only t. indica was the main reservoir but also other rodents and mammalian hosts might be the reservoir hosts of zcl in the region. molecular and phylogenetic analyses confirmed the strength of haplotype variation maintaining the circulation of leishmania species in their reservoir hosts. results leishmania majo...

the genus allactaga is a group of rodents with five morphospecies distributed in the iranian plateau. in order to conduct a taxonomic revision at the species level, 27 individuals were collected in the iranian plateau from localities typical of each species. phylogenetic relationships within species were analyzed using cytochrome oxidase subunit i and morphometric data. maximum parsimony, maxim...
