“…Such fine-scale population differentiation at the intraspecific level is very rare among rodents and small mammals. Phylogeographic studies available for some mammal species widespread in Southeast Asia have identified phylogeographic patterns with less genetic structure (Gorog et al 2004;Campbell et al 2004;Patou et al 2009;Patou et al 2010). Fine-scale population differentiation similar to that observed for L. neilli has been reported for very few mammal species strongly associated with a particular habitat, like the rodent species Laonastes aenigmamus, which is also highly endemic to Southeast Asian karst habitats (Rivière-Dobigny et al 2011) and the fruit bat Thoopterus nigrescens endemic to Sulawesi and Mollucan Island chain and strongly associated with primary forest (Campbell et al 2007).…”

Leopoldamys neilli is a threatened murine rodent species endemic to limestone karsts of Thailand. We have studied the phylogeography of L. neilli using two mitochondrial markers (cytb, COI) and one nuclear fragment (bfibr), in order to assess the influence of its endemicity to karst habitat. One hundred fifteen individuals of L. neilli were collected in 20 localities throughout the geographic range of this species in Thailand. Our study revealed strong geographic structure of the mtDNA genetic diversity: six highly differentiated, allopatric genetic lineages were observed in our dataset. They exhibit a very high degree of genetic divergence, low gene flow among lineages and low levels of haplotype and nucleotide diversities within lineages. Our results suggest that L. neilli's populations are highly fragmented due to the scattered distribution of its karst habitat. The most divergent lineage includes the populations from western Thailand, which have been separated from the other genetic lineages since at least the Early Pleistocene. The other lineages are more closely related and have diverged since the Middle Pleistocene. This study revealed an unexpected high level of genetic differentiation within L. neilli and highlighted the high endemicity of this species to limestone karsts. Our results enhance the importance of protecting limestone habitats to preserve not only the species but also intraspecific diversity.

“…Not only have new species been discovered in areas not previously or recently studied (Bates et al 2004(Bates et al , 2007bMatveev and Csorba 2007), but they have also been found in relatively well-known localities as a consequence of greater research intensity (e.g., Francis et al 2007a). Detailed reviews of museum collections have identiWed further additions (e.g., Helgen et al 2007;Bates et al 2007a), and the increasing use of molecular techniques is proving invaluable in elucidating hitherto hidden species diversity within cryptic species complexes (e.g., Kingston et al 2001;Francis et al 2007a, b) and clarifying relationships among them (Campbell et al 2004;Thabah et al 2006).…”

Research priorities for bat conservation in Southeast Asia: a consensus approach

Southeast Asia is a critical area for biodiversity conservation; levels of species richness and endemism are among the highest in the world, but rapid land-use changes endanger much of the region's fauna. Bats are a critical component of this diversity, comprising nearly a third of Southeast Asia's mammal species and providing vital ecological and economic services. However, nearly half the species are of conservation concern and as many as 40% of bat species are predicted to be extinct by the end of this century if current deforestation rates persist. Conservation eVorts are urgently needed, and the taxonomic continuity of Southeast Asia and the prevalence of major threats throughout suggest that a region-wide initiative could be an eVective approach. The Southeast Asian Bat Conservation Research Unit (SEABCRU) was established in 2007 to provide an organizational framework to both accelerate the advancement of bat research, and to coordinate conservation eVorts. The SEABCRU is an informal collaboration among institutes, NGOs and individuals and provides a web-based forum for the growing number of researchers and outreach workers to interact and coordinate activities. It was launched at the 1st International Southeast Asian Bat Conference in Thailand (May 2007), during which a forum was held to derive conservation research priorities using a consensus approach. Four priorities were identiWed by participants: Xying fox conservation and monitoring, taxonomy, conservation of cave-dependent bats, and conservation of forestdependent bats. Here I provide an overview of the rationales behind these priorities and list the speciWc recommendations for the actions identiWed.

“…When repeated several times throughout the Pleistocene, this system has the potential to generate a lot of diversity. This hypothesis has been supported by low levels of genetic divergence between populations of some Sunda shelf mammals (Campbell et al, 2004(Campbell et al, , 2006Gorog et al, 2004;Lucchini et al, 2005;Roos et al, 2003). However, the vegetation during the Pleistocene glacial periods was undoubtedly very different from the present, and the interactions between climate and sea level and their effects on the distribution of the fauna and flora is complex (van den Bergh et al, 2001).…”
