Background Ocbil theory aims to develop hypotheses explaining the evolution and ecology
of, and best conservation practices for, biota on very old, climatically buffered, infertile …

The nature and definition of species continue to be matters of debate. Current views of
species often focus on their nature as lineages—maximal reproductive communities through …

The Brazilian mountain ranges from the Guiana Shield highlands are largely unexplored,
with an understudied herpetofauna. Here the amphibian and reptile species diversity of the …

The Megophrys major species group (MMSG) is composed of typically medium to large
sized frogs. Within the genus, it is the most geographically widespread clade ranging from …

Investigations of biodiversity, biogeography, and ecological processes rely on the
identification of “species” as biologically significant, natural units of evolution. In this context …

Background Corybas taliensis is an endemic species of sky islands in China. Its habitat is
fragile and unstable, and it is likely that the species is threatened. However, it is difficult to …

Abstract “Sky island” species diversification contributes greatly to mountainous biodiversity.
However, the underlying genomic divergence and the inferred drivers remain largely …

Multi-locus nuclear DNA data were used to delimit species of fringe-toed lizards of the Uma
notata complex, which are specialized for living in wind-blown sand habitats in the deserts of …

Ecnomiohyla tuberculosa is an Amazonian hylid of uncertain phylogenetic position. Herein
DNA sequences of mitochondrial and nuclear genes are used to determine its phylogenetic …

A central goal of comparative phylogeography is to understand how species‐specific traits
interact with geomorphological history to govern the geographic distribution of genetic …
