Soon after the description of the Sail Mountain Dragon (Japalura vela) from eastern Tibet, China, two more new species of Japalura, namely J. laeviventris and J. iadina, were described from the approximate same region in the Hengduan Mountain Range of China. Despite the distinct scalation and coloration, the two new species have long been confused with a known congener, J. flaviceps. Like other...

A new species of dragon lizard was discovered from the valleys Eastern Tibet, PR China, which provides further information about the biogeography of the river system in the region. As the direct result of continental collision, the Tibetan Plateau and its surrounding regions provide an ideal system to investigate how complex geographic events affect the evolution of living organisms. However, because of...

A new species of the agamid genus Japalura is described based on 15 specimens from the upper Lancang (Mekong) Valley of eastern Tibet, PR China. Populations of the new species, Japalura vela sp. nov., were previously recognized as J. flaviceps. The new species is morphologically most similar to J. batangensis, J. micangshanensis, J. variegata, and J. zhaoermii, but is distinguished from the...

We present a near comprehensive, densely sampled, multilocus phylogenetic estimate of species relationships within the anuran family Ceratobatrachidae, a morphologically and ecologically diverse group of frogs from the island archi- pelagos of Southeast Asia and the South-West Pacific. Ceratobatrachid frogs consist of three clades: a small clade of enigmatic, primarily high-elevation, semi-aquatic Sundaland species currently assigned to Ingerana (for which we erect...

Kai Wang, recent graduate of Washington State University, will be joining the Siler Lab in July 2015 as a Master’s Student.  Prior to his arrival here in Oklahoma, Kai spent time in the field in China and Tibet. Kai was in western Yunnan Province (specifically Tenchong and Husa) in China, from April 15-25 doing an independent research study on a species of Tylotriton newt....

  Elyse Freitas and I are halfway through a three week visit to Southeast Asia.  We spent a week in Thailand working with collaborators and visiting a wonderful national park (Sakaerat Research Station), and now are in the Philippines.  During our visit to Sakaerat, we encountered an amazing swarm of butterflies of various species, all of which were, well, quite friendly… Internet is...

Although landscape features such as mountains and rivers are recognized often as limiting factors to amphibian dispersal and gene flow, a limited number of studies have investigated such patterns across Southeast Asia. A perfect example of this is Thailand, located in one of the world’s biodiversity hotspot regions. Thailand represents the corridor between mainland Asia and the Sunda Shelf, a famous and...

Introduction A large array of species can accumulate on islands because the organisms that end up colonizing (establishing a new population in) these new habitats are physically separated from the original population they branched off from and thus proceed on their own evolutionary course. Successful colonization is affected by many factors, including ocean currents, competition between organisms, and the reproductive, behavioral, and...


Research 11.01.14

Adaptive radiations are the rapid accumulation of new species accompanied by adaptation to a diversity of habitats and environments that have specific requirements for habitation. This adaptation is typically observed through different corresponding physical changes. By broadly framing evolutionary radiations as the accumulation of both lineages and observable characteristics, comparisons among groups become focused not on the absolute number of lineages or...


Research 10.22.14

The Philippines represent an ideal region for examining the effects of geologic and climatic influences on evolutionary processes and the accumulation of new species. Though the monitor lizard is the target of conservation efforts, little research has looked at the geological processes which have shaped the evolution and distribution of this group. Asian water monitors (Varanus salvator Complex) are distributed throughout a...

Researchers want to know more about the evolutionary history and achieve a greater understanding of the diversity of land vertebrates in the Philippines. Though technological and statistical tools can help with this understanding, other problems have gotten in the way and research has only recently begun to accumulate. Looking at two species of Old World tree frogs – Rhacophorus bimaculatus and Kurixalus...
