Studies of the diversity of Philippine amphibians and reptiles have resulted in the continued description of cryptic species. Species formerly thought to range across multiple recognized faunal regions are now considered to be assemblages of multiple unique species, each restricted to a single faunal region. This pattern continues to hold true when considering Philippine skinks of the genus Brachymeles. Recent studies have...

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...

As part of the Spring 2015 Herpetology Course (BIOL 4083) taught by Dr. Cameron Siler at the University of Oklahoma, students took part in a semester long, small group writing assignment that formed a large basis of their final course grade. The class was broken up into three groups of seven or eight students, and each group was assigned a distinct lineage of...

Cameron and Nick of the Siler Lab are joined in the Philippines by Sam Noble Museum Invertebrates Curator, Dr. Katrina Menard, University of South Dakota Herpetology PhD candidate, Drew Davis, and Yale University Post-Doc Dr. Oliver Griffith.  All five researchers, plus their Philippine field crew, have spent the last 1.5 weeks in Aurora Province, Luzon Island, Philippines and have collected ~380 herptiles (including...

One of the trickiest aspects of being a graduate student is obtaining funding to conduct new research. Just like an entrepreneur, acquiring funding through fellowships and grants involves convincing others of the importance of your particular research project. This is the case for nearly all funding sources, regardless of size. Recently, I was able to accomplish this goal and receive funding from...

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...

In this paper, a new species of nematode helminth parasite is described: Cosmocerca leytensis. In addition, this paper represents the first descriptive list of parasites found in the gecko, Cytodactylus gubuaot, which is known to reside only on the Leyte Island of the Philippines. Although C. leytensis is the 30th species within the genus, it is the first to be found from...

Cosmocerca leytensis sp. nov. (Ascaridida, Cosmocercidae) from the large intestine of Cyrtodactylus gubaot (Squamata: Gekkonidae) collected on Leyte Island, Philippines is described and illustrated. Cosmocerca leytensis sp. nov. is the 30th species assigned to the genus, the 4th from the Oriental region, and the first from the Philippine Islands. The new species is most similar to those species possessing 4 pairs of...
