Article
Few species have been of more disputed affinities than the red or lesser panda (Ailurus fulgens), an endangered endemic Southeast Asian vegetarian member of the placental mammalian order Carnivora. This peculiar carnivoran has mostly been classified with raccoons (Procyonidae) or bears (Ursidae), grouped with the giant panda (Ailuropoda melanoleuca...

We analyzed a concatenated (8492 bp) nuclear–mitochondrial DNA data set from 44 musteloids (including the first genetic data for Lyncodon patagonicus) with parsimony, maximum likelihood, and Bayesian methods of phylogenetic and biogeographic inference and two Bayesian methods of chronological inference. Here we show that Musteloidea emerged approxi...

Umami is one of basic tastes that humans and other vertebrates can perceive. This taste is elicited by L-amino acids and thus has a special role of detecting nutritious, protein-rich food. The T1R1 + T1R3 heterodimer acts as the principal umami receptor. The T1R1 protein is encoded by the Tas1r1 gene. We report multiple inactivating (pseudogenizing...

The effects of a few decades of habitat fragmentation on the population genetic diversity of the large Japanese field mouse, Apodemus speciosus, in the forest region around Fukuyama University was assessed with approximate 300 bp nucleotide sequences of the mitochondrial D-loop region. Two independently isolated internal populations within the camp...
Chapter
Recent advancements in phylogenetic resolution at higher taxonomic levels within the mammalian order Carnivora have been stimulated by the increasing application of nuclear DNA, which is less homoplastic than mitochondrial DNA, and therefore better suited for studying deep‐level (e.g. among genera or older) relationships. Immense progress in sequen...
Chapter
Small carnivores – here defined as members of the mammalian Order Carnivora with a body mass < 21.5 kg – occur worldwide, including in Oceania, following introductions. They are represented by 210 to 282 species, which corresponds to around 90% of terrestrial carnivores globally. Some species are endemic to one or two countries (sometimes only isla...
Book
Full-text available
This book focuses on the 232 species of the mammalian Order Carnivora with an average body mass < 21.5 kg. Small carnivores inhabit virtually all of the Earth's ecosystems, adopting terrestrial, semi-fossorial, (semi-)arboreal or (semi-)aquatic lifestyles. They occupy multiple trophic levels and therefore play important roles in the regulation of e...
Article
Full-text available
The current distributions of organisms have been shaped by both current and past geographical barriers. However, it remains unclear how past geographical factors—currently cryptic on the sea floor—affected the current distributions of terrestrial animals. Here, we examined the effects of currently cryptic ancient rivers on current genetic different...
Article
Full-text available
We used DNA metabarcoding to assess the seasonal diets of the large Japanese wood mouse, Apodemus speciosus (Muridae, Rodentia), in forest edges adjacent to citrus orchards on Innoshima Island, Japan. We used one chloroplast and three mitochondrial DNA barcoding markers to determine mouse diets. Among the various plant and invertebrate diets, A. sp...
Article
Nucleotide sequences of the mitochondrial D-loop region were examined in three wild rodents (Apodemus argenteus, Apodemus speciosus, and Myodes smithii) on the northern slope of Mt. Fuji, the highest mountain in Japan, to elucidate the past evolutionary and present anthropogenic processes shaping their genetic diversity. Nucleotide diversity, media...
Article
Aim: Pinnipeds are thought to have evolved from a North Pacific ancestor, although some fossil evidence suggests a nonmarine Arctic origin and separate invasions into the North Pacific and North Atlantic. We here set out to test differing hypotheses about the origin of pinnipeds through identification and age estimation of pinniped marine invasions...

Article
The origin of the mammalian order Eulipotyphla has been debated intensively with arguments around whether they began diversifying before or after the Cretaceous-Palaeogene (K-Pg) boundary at 66 Ma. Here, we used an in-solution nucleotide capture method and next generation DNA sequencing to determine the sequence of hundreds of ultra-conserved eleme...

Recently, Stewart et al. (2017) investigated the origins of contemporary fisher populations in the Cooking Lake Moraine (CLM) of east-central Alberta, Canada, where fishers (Pekania pennanti) from Ontario and Manitoba, Canada were reintroduced in the early 1990s. To address this objective, Stewart et al. (2017) compared microsatellite alleles from...
Article
Plant diets of 2 sympatric species of wood mice in Japan (Apodemus argenteus and A. speciosus) were determined by DNA meta-barcoding analyses of feces using the nucleotide sequences of the chloroplast trnL P6 loop intron region as a molecular marker. The 2 species showed a relatively large degree of niche overlap in plant dietary profiles, feeding...
Article
To study the effects of post-glacial isolation by islands on population genetic diversity and differentiation of the large Japanese field mouse, Apodemus speciosus, we examined partial nucleotide sequences of the mitochondrial Dloop region (ca. 300 bp) in 231 individuals collected from islands in the Seto Inland Sea and adjacent regions on Honshu a...
Chapter
To elucidate the origins of the Japanese mammalian fauna from the perspectives of biogeography and community ecology, I reviewed molecular phylogenetic and phylogeographic studies for all non-volant terrestrial mammals indigenous to the Japanese Archipelago (63 species), with a particular focus on obtaining reliable chronological data. The results...

Few organisms in the superfamily Musteloidea (Carnivora, Caniformia) have shown more controversial systematic relationships than the badgers. Six genera encompassing 16 species are dubbed " badger " , all of which have strong claws and short powerful limbs adapted to their fossorial lifestyle. Badgers have occasionally been classified into a single...
Article
We examined the nucleotide sequences of the mitochondrial NADH dehydrogenase subunit 2 gene (976 base pairs) for 279 individuals of the sable Martes zibellina (Carnivora, Mustelidae), derived from diverse areas throughout the regions of the Ural Mountains to the Russian Far East on the Eurasian continent and the peripheral peninsula (Kamchatka) and...
Conference Paper
Full-text available
In comparison with large carnivores (order Carnivora), small carnivores are generally considered as less charismatic, and with the exception of a few social species (e.g. meerkats, European badger), they have been subjected to proportionately less research work. However, small carnivores play important roles in ecosystem function (e.g. seed dispers...

We examined sequence variation in mitochondrial and nuclear genes of seven species of the genus Martes (Mustelidae, Carnivora): Martes americana (American marten), Martes flavigula (yellow-throated marten), Martes foina (beech marten), Martes martes (pine marten), Martes melampus (Japanese marten), Martes pennanti (fisher) and Martes zibellina (sab...
Article
The red (or lesser) panda, Ailurus fulgens (Ailuridae), is a vegetarian species in the order Carnivora (meaning “flesh-eating”). Owing to the primitive and highly specialized morphological characteristics of this species, resolution of its systematic status has been a riddle in evolutionary studies for almost two centuries. In this review, we provi...
Article
Phylogeographic history of two Martes (Carnivora, Mustelidae) species inhabiting the Japanese archipelagos, the Japanese marten (M. melampus) and the sable (M. zibellina), was reviewed on the basis of the current evidence on molecular data. The genetic diversity of the possibly neutral mitochondrial DNA (mtDNA) suggested that geographic demarcation...

Phylogenetic relationships among species of the family Mustelidae were examined using the combined nucleotide sequences of the three mitochondrial genetic loci (cytochrome b (MT-CYB; 1140 bp), NADH dehydrogenase subunit 2 (MT-ND2; 1044 bp), and displacement loop (MT-DLOOP; 540 bp)), with special emphasis on the phylogenetic history of four Taiwanes...
Article
Missing data are commonly thought to impede a resolved or accurate reconstruction of phylogenetic relationships, and probabilistic analysis techniques are increasingly viewed as less vulnerable to the negative effects of data incompleteness than parsimony analyses. We test both assumptions empirically by conducting parsimony and Bayesian analyses o...
Article
Rodents belonging to the subfamily Gerbillinae and living in the Xinjiang-Uygur autonomous region of China were collected in field surveys between 2001 and 2003. We found four Meriones species, including M. chengi M. liycus, M. meridianus, and M. tamariscinus, as well as related species from different genera, Rhombomys opimus and Brachiones przewal...

Nucleotide sequences of the intron regions and UTRs (Untranslated regions) of the hemoglobin beta adult genes, b1 and b2, and of the intergenic spacer region were determined for mouse strains representing the d, p, and w1 hemoglobin haplotypes defined by protein electrophoretic analyses. The hypothesis of recombination of the b1 and b2 genes betwee...
Article
Considerable long-standing controversy and confusion surround the phylogenetic affinities of pinnipeds, the largely marine group of “fin-footed” members of the placental mammalian order Carnivora. Until most recently, the two major competing hypotheses were that the pinnipeds have a single (monophyletic) origin from a bear-like ancestor, or that th...
