The small uninhabited island of Monuriki (40.4 ha) in western Fiji is of national and international conservation concern for its several protected species. Exotic invasive species and a Category 5 cyclone have exacerbated conservation challenges. The cooperation of local, national, and international stakeholders continues to be crucial in restoration of the island’s native flora and fauna. This summary presents a timeline of...

Regions with complex geological histories often have diverse and highly endemic biotas, yet inferring the ecological and historical processes shaping this relationship remains challenging. Here, in the context of the taxon cycle model of insular community assembly,we investigate patterns of lineage diversity and habitat usage in a newly characterized vertebrate radiation centred upon the world’s most geologically complex insular region: island arcs...

Lasting thoughts Overall, my summer expedition to the eastern Philippines reinforced my strong believe that it is imperative for the research and conservation communities to emphasize the importance of the Philippine rainforest to such an amazing diversity of life. As reported by Conservation International, “this country is one of the few nations that is, in its entirety, both a biodiversity hotspot and...

They all come out at night… In a tropical region, the lush jungle, hot and humid climate, and high volume of rain usually make for the most productive herpetological field surveys, or the best “herping” (searching for reptiles and amphibians). Some people go fishing in their free time, but us “crazy” amphibian and reptile people go herpin’. And some times, as in...

Let’s talk insects So I found myself in an incredible forest at the foot of Mt. Huraw in northern Samar Island (eastern Philippines). The price of beauty for this rarely seen primary and secondary growth forest in the country was definitely the climate and insects. It was either about 100 degrees with 99% humidity, or about 90 degrees with torrential, down-pouring rain...

Biodiversity Survey in the Philippines This summer, I was fortunate enough to join a team of international biologists and participate in a four-week biodiversity study on the island of Samar in the southeastern Philippines. This expedition was funded by an NSF RAPID grant and lead by the University of Kansas (KU; my alma mater), and the University of Oklahoma (OU), both of...

We describe two new species of morphologically cryptic monitor lizards (genus Varanus) from the Philippine Archipelago: Varanus dalubhasa sp. nov. and V. bangonorum sp. nov. These two distinct evolutionary lineages are members of the V. salvator species complex, and historically have been considered conspecific with the widespread, northern Philippine V. marmoratus. However, the new species each share closer phylogenetic affinities with V....

We provide the first report on the diversity of amphibians and reptiles of the northern Sierra Madre Mountain Range, northeast Luzon Island, Philippines. Based on new data from extensive previously unpublished surveys, fieldwork, and museum records we can tell that this region is quite diverse. At least 101 herp species are present and now well documented in this region (29 amphibians, 30...

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...
