Abstract Surveys of small mammals on carefully selected mountains and mountain ranges on Luzon Island, Philippines, since 2000 have led to the discovery of seven previously unknown species of forest mice, Apomys, a remarkable radiation on just a portion of one island. On the basis of morphological and cytochrome (cyt) b DNA sequence data presented here, we propose a new subgenus, Megapomys, to include the large-bodied members of the genus, which form a monophyletic unit of relatively large mice… 

Three New Species of Musseromys (Muridae, Rodentia), the Endemic Philippine Tree Mouse from Luzon Island

Three new species of Musseromys from the mountains of northern Luzon are described and name based on morphological and DNA sequence data, including the smallest-known members of the cloud rat clade of endemic Philippine murids.

Archboldomys (Muridae: Murinae) Reconsidered: A New Genus and Three New Species of Shrew Mice from Luzon Island, Philippines

Reevaluation of the presumed morphological synapomorphies among these shrew mice, together with analyses of karyological and gene-sequence data, support the presence of Soricomys, new genus, and their phylogenetic relationships, biogeography, and conservation are discussed.

A new species of Batomys (Muridae, Rodentia) from southern Luzon Island, Philippines

A new species of Batomys granti is described from Mt. Isarog, southern Luzon, and is separated from the nearest known population of B. granti by about 450 km, indicating that it is a nocturnal herbivore.

Chapter 3: The Mammals of the Mingan Mountains, Luzon: Evidence for a New Center of Mammalian Endemism

The Mingan Mountains, with either three or four endemic species, are clearly a significant center of mammalian endemism, deserving of conservation.

Morphological and Geographic Definitions of the Sulawesian Shrew Rats Echiothrix leucura and E. centrosa (Muridae, Murinae), and Description of a New Species of Sucking Louse (Phthiraptera: Anoplura)

The present report documents morphological and distributional limits of species in Echiothrix, places one of those species in an ecological and parasitological landscape and analyses of morphometric traits derived primarily from cranial and dental measurements document the presence of two species.

The first fossil record of endemic murid rodents from the Philippines: A late Pleistocene cave fauna from northern Luzon

Abstract Excavations in Callao Cave, in the lowland (ca. 85 m elevation) Cagayan River Valley of northeastern Luzon, Philippines, have produced the first fossils of any endemic genera of Philippine

Molecular and morphological systematics of the Bunomys division (Rodentia: Muridae), an endemic radiation on Sulawesi

A five‐locus phylogeny and linear cranial morphology is combined to better understand the taxonomy and local scales of endemism within the Bunomys division on Sulawesi and resurrected Frateromys, a genus under which B. fratrorum was once placed, and returning Paruromys dominator to Taeromys.

A Hog-Nosed Shrew Rat (Rodentia: Muridae) from Sulawesi Island, Indonesia

Bayesian and likelihood analyses of DNA sequences concatenated from 5 unlinked loci infer the new shrew rat as sister to a clade consisting of Melasmothrix, Paucidentomys, and Echiothsrix, suggesting that Sulawesi shrew rats represent aClade.

Chapter 4: Diversity of Small Mammals in Montane and Mossy Forests on Mount Cetaceo, Cagayan Province, Luzon

Abstract We surveyed non-volant mammals in montane (1300 and 1400 m) and mossy forest (1500 and 1550 m) on Mount Cetaceo in the northern Sierra Madre of northeast Luzon in 2004 and 2005. We recorded

Nyctalus plancyi and Falsistrellus petersi (Chiroptera: Vespertilionidae) from Northern Luzon, Philippines: Ecology, Phylogeny, and Biogeographic Implications

Nyctalus plancyi is the first mammal species documented to have colonized the main, oceanic body of the Philippines from the north (i.e., Taiwan or mainland China), rather than from the south (Borneo, Sulawesi, or New Guinea).



A New Species of Forest Mouse, Genus Apomys (Mammalia: Rodentia: Muridae), from Camiguin Island, Philippines

A previously unknown species of Philippine forest mouse of the endemic Philippine genus Apomys is named and described, one of two species of mammals now known to be endemic to Camiguin, the other being Bullimus gamay.

Chapter 7. A New Genus and Species of Small ‘Tree-Mouse’ (Rodentia, Muridae) Related to the Philippine Giant Cloud Rats

The discovery of the new mouse from Mt. Banahaw–San Cristobal Natural Park, Quezon Province, Luzon Island, Philippines, reveals an even greater degree of diversification within the giant cloud rat clade than recognized previously, and adds to the 21 previously known genera of mammals endemic to the Philippines.


The discovery of locally endemic species of Rhynchomys both confirms the existence of multiple centers of endemism on Luzon and underscores the need to establish and maintain additional protected areas on the island.

A review of the genera Crunomys and Archboldomys (Rodentia: Muridae: Murinae) : with descriptions of two new species from the Philippines / Eric A. Rickart ... [et al.].

Members of both genera Crunomys and Archboldomys are relatively small, ground-dwelling rodents that apparently are diurnal and insectivorous and have a broad distribution that includes much of the Philippines as well as Sulawesi.

A new species of the shrew‐mouse, Archboldomys (Rodentia: Muridae: Murinae), from the Philippines

Abstract A new species of murid rodent belonging to the ‘shrew‐mouse’ genus Archboldomys is described from Kalinga Province in northern Luzon Island, Philippines. This is the third known species of

A new species of Batomys (Mammalia: Muridae) from eastern Mindanao Island, Philippines

This species corroborates the hypothesis that the island of Mindanao is comprised of multiple centers of endemism, of which the southeastern highland of Mt. Hamiguitan is one.


The new species differs from congeners in its combination of large body, very long tail, dark pelage, gracile cranium with a long rostrum, and highly compressed upper incisor; the most diagnostic features of the species are the extremely fine upper and lower incisors, and the degree of molar reduction and simplification.

Chapter 3: The Mammals of the Mingan Mountains, Luzon: Evidence for a New Center of Mammalian Endemism

The Mingan Mountains, with either three or four endemic species, are clearly a significant center of mammalian endemism, deserving of conservation.


Analysis of variation within the murine genera Celaenomys and Chrotomys supports the recognition of 4 named species occurring on the large islands of Luzon and Mindoro, as well as the description of a 5th species from Sibuyan, a small island in the central Philippines that has remained isolated from the other islands by deep water channels.

Chapter 2: Mammalian Diversity Patterns on Mount Palali, Caraballo Mountains, Luzon

It is concluded that all three rainforest types at all elevations, including newly regenerating forest, provide important habitat for mammals on Mount Palali, supporting the hypothesis that non-native small mammals are not successful in invading native habitats on oceanic islands when the native community of small mammals is diverse.
