“…Important habitats we observed that are critical to species survival include riparian vegetation, leaf litter, tree stumps, dead logs, fallen trees, tree foliage, swamps, and creeks, all of which are found in forested areas. Our observations are consistent with those from other studies Brown et al 2001Brown et al , 2012Brown et al , 2013bMcleod et al 2011;Siler et al 2011Siler et al , 2012Gaulke 2011;Devan-Song & Brown 2012;Plaza & Sanguila 2015;Siler et al 2016), emphasizing how these habitats are among the highest priority for research and conservation value.…”

“…In recent work of Siler et al (2011) in Aurora Province, the authors demonstrated that a single survey is not sufficient to assess the species diversity of an area Siler et al, 2011). In these and several other studies, authors nearly doubled species diversity for a given site with subsequent survey efforts (Brown et al , 2013bSiler et al 2011).…”

“…We observed this species on rocks along the river, in the northeast side of our campsite. It was previously thought to be uncommon and considered as a swamp species (Alcala & Brown 1998) until recent surveys (Denzer et al 1994;Beukema 2011;Siler et al 2011). Observations on the Sibuyan and Leyte islands Mallari et al 2013aMallari et al , b, 2014 revealed that this species is abundant and common in localities where it is known to occur (particularly in habitats such as flooded areas, stream banks and temporary pools).…”

Abstract. Despite extensive surveys conducted in the past, many remote areas in the Philippines remain unexplored and many species are unknown to science. The Mount Hamiguitan Range (MHR) is among these areas, containing large remaining forests tracts. In this study, we report new records of amphibians and reptiles from MHR and propose removing two species from the previously listed species from this mountain range. We used standardized techniques to sample populations of amphibians and reptiles in fragmented forests of Mt. Hamiguitan. Our survey resulted in 16 new records of species (four frogs, three lizards and nine snakes). Combining our results with previous studies, the known species diversity from the MHR is now increased to a total of 61 taxa. Our results highlight the underestimated diversity of herpetofauna of Mt. Hamiguitan, and we discuss the importance of repeated surveys for determining species occurrences and assessing their conservation status.

“…They are commonly observed within rotting logs, in leaf litter, in the root networks of tree buttresses, as well as beneath rotting piles of coconuts (Siler et al 2012b). The species has been found to qualify for a conservation status of “Near Threatened” (NT; IUCN 2016; Siler et al 2012a,b). …”

“…These efforts have focused on the northern Babuyan and Batanes islands (Oliveros et al 2011), the large northern island of Luzon (McLeod et al 2011; Siler et al 2011a; Brown et al 1996, 2000a, 2012a, 2013a; Devan-Song and Brown 2012), and central island groups (Brown and Alcala 1961, 1964, 1986; Siler et al 2012a), but little recent activity has documented other parts of the archipelago, especially the western island of Palawan, the Sulu Archipelago, and portions of the large southern island of Mindanao (Leviton 1963; Brown and Alcala 1970a; Peterson et al 2008; Jones and Kennedy 2008; Siler et al 2009). Mindanao supports high levels of herpetological diversity (Taylor 1920a,b, 1921, 1922a,b; Brown and Alcala 1970; Brown et al 2013a; Diesmos et al 2015) and considerable endemism, despite its close proximity to the larger landmasses of Sundaland (Borneo, Sumatra, and Java) and Wallacea (Sulawesi; Fig.…”

We summarize all available amphibian and reptile species distribution data from the northeast Mindanao faunal region, including small islands associated with this subcenter of endemic vertebrate biodiversity. Together with all publicly available historical information from biodiversity repositories, we present new data from several major herpetological surveys, including recently conducted inventories on four major mountains of northeast Mindanao, and adjacent islands of Camiguin Sur, Dinagat, and Siargao. We present species accounts for all taxa, comment on unresolved taxonomic problems, and provide revisions to outdated IUCN conservation status assessments in cases where our new data significantly alter earlier classification status summaries. Together, our comprehensive analysis of this fauna suggests that the greater Mindanao faunal region possesses distinct subcenters of amphibian and reptile species diversity, and that until this area is revisited and its fauna and actually studied, with on-the-ground field work including targeted surveys of species distributions coupled to the study their natural history, our understanding of the diversity and conservation status of southern Philippine herpetological fauna will remain incomplete. Nevertheless, the northeast Mindanao geographical area (Caraga Region) appears to have the highest herpetological species diversity (at least 126 species) of any comparably-sized Philippine faunal subregion.

Of the 10,272 currently recognized reptile species, the trade of fewer than 8% are regulated by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the European Wildlife Trade Regulations (EWTR). However, the International Union for Conservation of Nature (IUCN) Red List has assessed 45% of the world's reptile species and determined that at least 1390 species are threatened by “biological resource use”. Of these, 355 species are intentionally targeted by collectors, including 194 non-CITES-listed species. Herein we review the global reptile pet trade, its impacts, and its contribution to the over-harvesting of species and populations, in light of current international law. Findings are based on an examination of relevant professional observations, online sources, and literature (e.g., applicable policies, taxonomy [reptile database], trade statistics [EUROSTAT], and conservation status [IUCN Red List]). Case studies are presented from the following countries and regions: Australia, Central America, China, Galapagos Islands (Ecuador), Germany, Europe, India, Indonesia (Kalimantan), Islamic Republic of Iran, Japan, Madagascar, Mexico, New Zealand, the Philippines, South Africa, Sri Lanka, Vietnam, Western Africa, and Western Asia. The European Union (EU) plays a major role in reptile trade. Between 2004 and 2014 (the period under study), the EU member states officially reported the import of 20,788,747 live reptiles. This review suggests that illegal trade activities involve species regulated under CITES, as well as species that are not CITES-regulated but nationally protected in their country of origin and often openly offered for sale in the EU. Further, these case studies demonstrate that regulations and enforcement in several countries are inadequate to prevent the overexploitation of species and to halt illegal trade activities.
