Here, we provide cytochrome b gene tree for over 50% of bat species (648 total taxa).
Cytb not only is the most widely available marker for most mammals, but also has been shown to be a particularly reliable phylogenetic marker (e.g. Thus according with prior analyses of other mammal groups    , the cytb gene tree can be expected to at least roughly approximate the species-level phylogeny of Chiroptera.
Both approaches make available useful research tools, which may have different strengths.The sequences were aligned in Mesquite , a trivial task given that it is a protein-coding gene with no implied gaps.The appropriate model for the Bayesian analysis was selected with j Modeltest  using the AIC criterion . Bayesian analysis was performed using Mr Bayes V3.1.2  with settings as in   with separate model estimation for first, second, and third codon positions.One simple reason for this focus is that general interest questions, such as where and how the major divisions of life fit together, can be answered through sampling relatively few taxa, in a relatively cost and time effective manner.Yet, more detailed species-level phylogenies, often lagging far behind, are the most useful tools for evolutionary and ecological analyses.We provide this phylogeny simply as an alternative tool to super-tree phylogenies, until more detailed studies become available.Cytochrome b sequences were downloaded from Gen Bank for 648 bats, including nearly 550 named species, and the remaining terminal taxa being subspecies or unidentified/undescribed species.Finding love is a challenging quest even in your home country.Dating internationally will either make it more so or raise the chance to finally get the partner you've been looking for all along. Despite their obvious utility, detailed species-level phylogenies are lacking for many groups, including several major mammalian lineages such as bats.We provide this phylogenetic hypothesis, and an analysis of divergence times, as tools for evolutionary and ecological studies that will be useful until more inclusive studies using multiple loci become available.
