Standardization and repeatability is at the heart of all scientific research, yet very little literature exists to standardize mor- phometric measurements within vertebrate groups. This is particularly true for amphibians. Our study attempts to rectify this lack of methodological standardization for the measurement of morphological characters in anurans through an ex- tensive literature survey of 136 species descriptions representing 45 currently recognized...

Despite the exceptionally high levels of vertebrate diversity in Southeast Asia, surprisingly little is known about the processes responsible for this occurrence. Recently, an increase in diversity of amphibians has been studied in the Philippines. One genus in particular, Sanguirana, a frog genus endemic to the Philippines, consists of seven species with distinct physical characteristics as well as one or two species...

Recent higher-level frog phylogenetic analyses have included a few members of the endemic Philippine frog genus Sanguirana. Although the monophyly of the group has never been disputed, the recent phylogenetically-supported inclusion of the Palawan Wood Frog (Sanguirana sanguinea) in this clade was highly unexpected. In addition, species boundaries and relationships remain unclear and new species continue to be discovered. We estimate the...
