Amphibians and Reptiles of Luzon Island (Philippines), VII: Herpetofauna of Ilocos Norte Province, Northern Cordillera Mountain Range
We report new distribution records for amphibians and reptiles from 20 localities within the northern Cordillera
Mountain Range of Ilocos Norte Province, Luzon Island, Philippines. Together with opportunistic collections of specimens
from past surveys, our new data result in a total of 58 amphibian and reptile species for Ilocos Norte Province and the
extreme northern Cordilleras—all of which constitute major geographic range extensions. We utilize new data and IUCN
formalized conservation assessment criteria to revise the conservation status of many species. Our results highlight the
degree to which fundamental distribution data are lacking for Luzon amphibians and reptiles and emphasize the manner
in which many current species assessments are based on incomplete data and, as a result, may be sorely misleading. The
complex biogeography of Luzon’s herpetofauna remains poorly understood, providing opportunities for future research
and conservation efforts once distribution patterns and local abundances are properly documented.http://creativecommons.org/licenses

Amphibians and Reptiles, Luzon Island, Aurora Province and Aurora Memorial National Park, Northern Philippines: New island distribution records
We report 35 new amphibian and reptile distribution records for two regions within the southern Sierra Madre
Mountain Range, Aurora Province, central Luzon Island, Philippines. Together with results of our previous survey work in
Aurora, our new data result in a total of 82 amphibian and reptile species for the area. These results highlight the degree
to which the island’s biodiversity continues to be underestimated and poorly understood. We report on observations of
rarely encountered species including the skink Sphenomorphus leucospilos, the forest gecko Luperosaurus cf. cumingii, and
a sensational new species of monitor lizard, Varanus bitatawa. Our recent collections clarify the conservation status of
the “critically endangered” Polillo Island forest frog Platymantis polillensis, now known to be widespread, abundant, and
common throughout Camarines Norte, Quezon, and Aurora Provinces on the adjacent mainland of Luzon Island. These
results add to our growing understanding of many species’ distributions in the region

Amphibians and reptiles, Romblon Island Group, central Philippines: comprehensive herpetofaunal inventory
We present results from several recent herpetological surveys in the Romblon Island Group (RIG), Romblon
Province, central Philippines. Together with a summary of historical museum records, our data document the occurrence
of 55 species of amphibians and reptiles in this small island group. Until the present effort, and despite past studies,
herpetological diversity of the RIG and their biogeographical affinities has remained poorly understood. We report on
observations of evolutionarily distinct amphibian species, including conspicuous, previously known, endemics like the
forest frogs Platymantis lawtoni and P. levigatus and two additional suspected undescribed species of Platymantis. Moderate
levels of reptile endemism prevail on these islands, including taxa like the karst forest gecko species Gekko romblon and the
newly discovered species G. coi. Although relatively small and less diverse than the surrounding landmasses, the islands
of Romblon Province contain remarkable levels of endemism when considered as percentage of the total fauna or per unit

Typhoon frequency and intensity across the Western Pacific Ocean north of the Equator, 1951 – 2014
Disturbance has been a repeated theme in ecology in recent decades, yet incorporating its frequency and pattern at broad spatial scales into ecological analyses has been difficult – rather, most environmental datasets used in broad-extent analyses represent average conditions. We present a detailed dataset summarizing the frequency (i.e., number of typhoons) and intensity (average and maximum windspeeds) of typhoons across the Western Pacific north of the Equator, based on data characterizing tracks for 1673 typhoons from the Japan Meteorological Center. The data presented are aggregated and resampled to 0.2° (~22 km at the Equator) spatial resolution; temporal coverage extends 1951 – 2014. We also present data specifically for prior to 1980 and after 1999, to respond to questions related to climate change, although no major changes were evident between the time periods
The herpetofauna of the Babuyan Islands, Northern Philippines
We document 52 species of amphibians and reptiles from the Babuyan Islands in the northern Philippines. Among these records, 12 species are endemic to the Babuyan Islands and another 18 are endemic to the Philippines. Prevalence of endemic forms in the island group is high, with 1–3 island-endemic species present in each of the major islands. The present-day assemblage of herpetofauna in the island group is attributed to dispersal from Luzon and subsequent diversification. No evidence of successful southward colonization of species from Taiwan is found. Based on data from our own surveys, and to enable future work, we provide an updated list of the species from the Babuyan and Batanes Island groups. Molecular phylogenetic studies are recommended to gain more insights into the evolutionary history of the island-endemic forms and the biogeography of the small islands between Luzon and Taiwan
A new species of Cosmocerca (Nematoda: Cosmoceridae and other helminths in Cyrtodactylus gubaot (Squamata: Gekkonidae) from the Philippines
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 plectanes, i.e., C. archeyi, C. australis, C. oroensis, and C sardiniae. Cosmocerca sardiniae lacks lateral alae; C. archeyi, C. australis, C. leytensis sp. nov. and C. oroensis possess lateral alae. Spicule length of C. oroensis is less than 75 ìm, while C. archeyi, C. australis, and C. leytensis sp. nov. have spicule lengths greater than 75 ìm. Males of C. australis possess 2 pairs of rosette caudal papillae, which are lacking in C. archeyi and C. leytensis sp. nov. Females of C. archeyi posses a conical tail, females of C. leytensis sp. nov. have a rounded posterior end supporting a flexible filament
