Research 10.27.14

Some of Southeast Asia’s most enigmatic reptile species include the arboreal (tree-dwelling), frugivorous (fruit-eating) monitor lizards of the central and northern Philippines. Comprised of just three known species, this distinct group has even been assigned to its own subgenus, Philippinosaurus on the basis on cranial features and dentition (characteristics of the teeth). Knowledge on the biology of Philippine frugivorous monitor lizards has...

Habitat destruction is a problem for all species, but it is especially detrimental to conservation efforts of large vertebrates with highly specialized habitats. Large-bodied sailfin lizards, which require lowland, costal and mangrove forests, have seen their suitable habitats shrink, leaving them with little area to live. In the past 75 years, degradation of the coastal forests and mangroves has lead to a...

Despite rampant coastal development throughout Southeast Asia and the Pacific, studies of conservation genetics and ecology of vulnerable, coastal species are rare. Large bodied vertebrates with highly specialized habitat requirements may be at particular risk of extinction due to habitat degradation and fragmentation, especially if these habitats are naturally patchily distributed, marginal, otherwise geographically limited, or associated in space with high human...

Aim To highlight the significant conservation challenge of evaluating peripheral endemic vertebrates in island archipelago systems and to assess empirically the complexities of approaches to conservation genetic studies across political and biogeographic boundaries. To demonstrate the poignant need for international collaboration and coordination when species delimitation problems with high conservation concern involve island endemics with biogeographically peripheral ranges. Location Southeast Asia, Lanyu...

Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its...

Island ecosystems often consist of many types of unique organisms and therefore are very important to conservation efforts. Deforestation, pollution, and a lack of protection of these islands cause many species to go endangered or extinct. In order to protect these endemic species it is important for scientists to study and identify the phylogenetic lineages of the many species living here. This...

Recent studies of forest lizards in Southeast Asia have revealed both physical and genetic differences within this family. These lizards are currently being threatened by the deforestation that is occurring in the region. Lizards in the Philippines are particularly vulnerable, as 84% of the lizard species there are found nowhere else on the planet. Though the threats faced by these lizards are...

We provide a phylogenetic and population genetic evaluation of the illegal pet and bush meat trade of monitor lizards in the Philippines. We use a molecular dataset assembled from vouchered samples with known localities throughout the country, as a reference for statistical phylogenetic, population genetic, and DNA barcoding analyses of genetic material obtained during a three year survey of the Manila pet...

We investigated phylogeography of Philippine slender toads (genus Ansonia) and used a temporal framework for diversification, statistical tests of alternate topologies, and Bayesian approaches to test previous hypotheses concerning dispersal to, and colonization routes within, the southern Philippine island of Mindanao. Two species of Ansonia previously have been documented, with ranges separated by an east–west split corresponding to the approximate boundaries of...
