    Abstract To mark A.R. Wallace's 200th birthday, we review the direct and indirect contributions he made to our understanding of the Indo‐Australian Archipelago's biogeography. He is widely known for his field research (1854–1862) and his 1863 boundary line separating the Oriental and Australasian faunal realms (between Bali and Lombok, Borneo and Sulawesi, and the Philippines and the Moluccas). Notably, though, he never accepted Huxley's ‘Wallace Line’ proposal (1868), whose northern part runs between the main Philippine islands and the Palawan Group to the west. Furthermore, in 1910, which was 3 years prior to his demise, he transferred Sulawesi's fauna to the Oriental realm. In 1924, Merrill introduced the ‘Wallacea’ transition zone. Although the label is today widely used to denote a sub‐region within the Indo‐Australian Archipelago between Wallace's 1863 line and Lydekker's 1896 line (first presented by Darlington in 1957), the western boundary was originally based on Huxley's line, and thus included the Philippine islands minus the Palawan group. Most biogeographers appear to be unaware of Merrill and his intention. Finally, recent attempts to define the faunal break have not led to a consensus view, despite the huge increase in primary data plus the application of modern analytical techniques. This reflects the complexities and diversity of the region's faunal distribution patterns, plus the differences in the ways that researchers choose to process their data.

    Abstract Due to its position between the highly distinct Oriental and Australasian biogeographical realms, much effort has been spent demarcating associated separations and transitions in the faunal assemblages of the Indo-Australian Archipelago. Initially, sharp boundary lines were proposed, with the earliest dating from the mid-1800s. Notably, the one published by Alfred R. Wallace in 1863, based upon land-mammal and land-bird distributions, has since achieved iconic status and today its significance is recognized well beyond the confines of the biogeography community. Over the next four decades many such divides were engraved onto plates and inked onto charts of SE Asia using additional information, different organisms or other criteria. However, it became apparent that, as Wallace had noted, all such lines were to some degree permeable, and by the 1880s transition zones were being put forward instead; the label 'Wallacea' was introduced in 1924. Interestingly, the last decade has seen new divides and sub-regions being proposed, some departing markedly from earlier offerings. Although currently there is general agreement regarding much of the terminology associated with both the lines and the areas, the record of publication indicates that this consensus has emerged obliquely, and in some cases is weakly founded. This review does not present new data nor new analyses; rather it summarizes the development of ideas and reflects upon attendant issues that have emerged. After reviewing the key proposals, recommendations are presented that should in future alleviate perceived difficulties or inadequacies. Reference to specific divides must be true to their original definitions; there are many instances where the secondary literature has portrayed them incorrectly and with some this has rippled through into later publications. Moreover, Wallace's 1863 line is not the one that he finally settled upon (in 1910); its path around Sulawesi was transferred from the west to the east of the Island. Ideally, Huxley's divide (1868) should carry his name rather than Wallace's; the latter never accepted the proposition. Lydekker's Line (1896) ought to be labelled the Heilprin-Lydekker Line in recognition of Angelo Heilprin's 1887 contribution. Concerning transition zones, ideally Wallacea should correspond to its original 1924 description, which incorporated the Philippine islands bar the Palawan group. Notably, though, a smaller form (introduced by Darlington in 1957, used frequently from 1998 onwards) in which all of the Philippine islands are excluded is entrenched within the recent literature, but this is often without evident justification. It should also be recognized that the 'reduced' (=southern) Wallacea area was effectively defined by Heilprin in 1887, but was then labelled the 'Austro-Malaysian Transition Zone'. Finally, the application in recent years of modern analytical techniques has not led to a consensus view on where the lines/areas should run/be placed; with such a large, diverse set of organisms, each with differing histories, this is perhaps not surprising.

    Abstract Island radiations represent unique evolutionary histories in unique ecological contexts. These radiations provide opportunities to investigate ecological diversification in groups that typically exhibit niche partitioning among their constituents, including partitioning of food resources. DNA metabarcoding produces finer levels of diet identification than traditional methods, allowing us to examine dietary niche partitioning in communities or clades in which species share superficially similar diets. Here, we use DNA metabarcoding to investigate dietary niche partitioning in an endemic radiation of mammals in the Philippines. Our data reveal niche partitioning as well as phylogenetically-uncorrelated adaptive evolution in this small mammal community. Because 70% of the focal species belong to the tribe Chrotomyini, an endemic Philippine radiation of murid rodents that feed extensively on earthworms, this study sheds light on dietary adaptation and its role in the co-occurrence of closely related species. Our results reveal fine-scale resource partitioning within this community; our data provide compelling evidence for niche partitioning of diet that was masked by previous diet categories and will help in further dissecting the model adaptive radiation of endemic small mammals on Luzon. This study reinforces the notion that DNA metabarcoding can be a valuable tool for investigating both ecological relationships and evolutionary ecology at the community and phylogenetic level, respectively.

    Abstract Podogymnura, a Philippine endemic genus of gymnures ("soft-furred hedgehogs"), has been known previously only from the highlands of central Mindanao (P. truei truei and P. t. minima) and from two small islands off the northeast tip of Mindanao (P. aureospinula). Based on a combination of mitochondrial genetic and qualitative and quantitative morphological data, we recognize P. minima, formerly considered a subspecies of P. truei, as a distinct species. We also recognize specimens from two little-studied montane regions of southeastern Mindanao, Mt. Hamiguitan and Mt. Kampalili, as a distinctive new species, P. intermedia n. sp. We estimate that dispersal of a common ancestor from Borneo to Mindanao ca. 1.9 to 3.5 Ma gave rise to Podogymnura, followed by speciation within Mindanao beginning 0.53 to 0.97 Ma. These results further increase the rich diversity of mammals on Mindanao, and underscore the importance of the eastern Mindanao highlands as a likely important but little-studied center of Philippine mammalian diversity.

    Abstract Existing radiations in a spatially limited system such as an oceanic island may limit the ecological opportunity experienced by later colonists, resulting in lower macroevolutionary rates for secondary radiations. Additionally, potential colonists may be competitively excluded by these incumbent (resident) species, unless they are biologically distinct (biotic filtering). The extant phenotypic diversity of secondary colonists may thus be impacted by lower rates of phenotypic evolution, exclusion from certain phenotypes, and transitions to new morphotypes to escape competition from incumbent lineages. We used geometric morphometric methods to test whether the rates and patterns of mandibular evolution of the Luzon "old endemic" rodent clades, Phloeomyini and Chrotomyini, are consistent with these predictions. Each clade occupied nearly completely separate shape space and partially separate size space. We detected limited support for decelerating and clade-specific evolutionary rates for both shape and size, with strong evidence for a shift in evolutionary mode within Chrotomyini. Our results suggest that decelerating phenotypic evolutionary rates are not a necessary result of incumbency interactions; rather, incumbency effects may be more likely to determine which clades can become established in the system. Nonincumbent clades that pass a biotic filter can potentially exhibit relatively unfettered evolution.

    Abstract Bats of the genus Kerivoula (Mammalia, Chiroptera) are widespread in the Philippines with four reported species, but have been poorly known due to a paucity of specimens. We provide the first molecular phylogeny for Philippine Kerivoula, which supports the existence of four distinct clades that we treat as species (K. hardwickii, K. papillosa, K. pellucida, and K. whiteheadi); these four overlap broadly geographically. Each of these may be recognized on the basis of cytochrome b sequences and external and craniodental morphology. Detailed examination of K. pellucida shows little geographic differentiation within the Philippines, but they differ subtly from those on the Sunda Shelf. We consider K. whiteheadi to be composed of four recognizable clades, each restricted to a geographic region within the Philippines. We consider K. bicolor, from peninsular Thailand, and K. pusilla, from Borneo, to be distinct from K. whiteheadi. Our data indicate the presence of two species within the Philippines currently lumped as K. hardwickii; further study of these is needed. A calibrated phylogeny suggests that Kerivoula began arriving in the Philippines about 10 MYA, with each of the four current lineages arriving independently.

    Abstract Diversity-dependent cladogenesis occurs when a colonizing lineage exhibits increasing interspecific competition as it ecologically diversifies. Repeated colonization of a region by closely related taxa may cause similar effects as species within each lineage compete with one another. This may be particularly relevant for secondary colonists, which could experience limited diversification due to competition with earlier, incumbent colonists over evolutionary time. We tested the hypothesis that an incumbent lineage may diminish the diversification of secondary colonists in two speciose clades of Philippine "Old Endemic" murine rodents-Phloeomyini and Chrotomyini-on the relatively old oceanic island of Luzon. Although phylogenetic analyses confirm the independent, noncontemporaneous colonization of Luzon by the ancestors of these two clades, we found no support for arrested diversification in either. Rather, it appears that diversification of both clades resulted from constant-rate processes that were either uniform or favored the secondary colonists (Chrotomyini), depending on the method used. Our results suggest that ecological incumbency has not played an important role in determining lineage diversification among Luzon murines, despite sympatric occurrence by constituent species within each lineage, and a substantial head start for the primary colonists.
