Primate Research Institute, Kyoto University1Toyama Municipal Family Park Zoo 2
The time it takes for ingested seeds to pass through the gut of animals is an important aspect of endozoochorousseed dispersal because it influences seed dispersal distance. Variations in the physical characteristics of seeds,
such as their weight, volume, and specific gravity, can affect their movement through the gastrointestinal systemof a given animal. We conducted feeding experiments with captive Japanese martens, Martes melampus (n = 4),
at Toyama Municipal Family Park Zoo, central Japan to examine the effects of the physical characteristics ofseeds on their passage times. The mean (±SD) transit time, mean retention time, and time of last appearance offour different types of commercial seeds were 2.6±0.3 h (range 0.6 – 5.4), 9.7±1.1 h (3.8 – 17.3), and 23.8±3.1 h(12.2 – 51.8), respectively. All of these values are greater than those found during previous experiments
conducted with mustelids. Similar to previous studies, however, none of these passage time variables wascorrelated with the physical characteristics of seeds. Our results thus indicate that martens disperse seeds ofdifferent plant species, whose size, volume, and specific gravity all fall within the range of those used in thepresent study, from parent-plants at similar distances.

   The difference of pelvic shape between terrestrial and semiaquatic carnivores
Keiko Fukuoka!, Masaharu Motokawa"
Grad. sch. of Sci. Kyoto Univ!, The Kyoto University Museum"
In this study, the morphology of carnivoran pelvis is compared using three dimensional geometricmorphometrics. This study focuses on the pelvic difference between terrestrial and semiaquatic carnivores. 38
landmarks are collected from a total of 76 individuals of 7 pinnipeds, 4 species nearly living in water (Enhydra
lutris, Lutra lutra, Mustela vison, and Ursus maritimus), and 7 terrestrial species.
The results show that species more adapted for the life in water have more conical shaped pelvis. This change
was characterized by that the ischial tuberosity went inner and the pubic symphysis went caudal direct.
Semiaquatic mammals might take this less water resistance shape due to buoyancy although these changes seemto be disadvantageous in terrestrial species since this makes it difficult to sustain their body weight and internalorgans. The pelvic shape change is influenced by the life style of its animal. This change for semiaquatic life has
occurred in different clades such as Otariidae and Phocidae in parallel.
   Sexual dimorphism of skull allometry in the Japanese weasel Mustela itatsi

Dept. Zool., Grad. Sch. Sci., Kyoto Univ.1, Kyoto University Museum, Kyoto Univ.2
The Japanese weasel Mustela itatsi, an endemic species of Japan is known to have remarkable sexual size
dimorphism (SSD). It is reported that SSD generally increases proportionally with body size in Mustela.
However, M. itatsi shows greater SSD than expected for their given size. Although size difference has been thefocus of most previous studies on sexual dimorphism of Mustela skull, shape difference between sexes has
seldom been quantitatively evaluated. In this study, we analyzed sexual difference of skull shape by comparing
bivariate allometric patterns of 44 skull measurements against condylobasal length (CBL), using 30 adultspecimens of M. itatsi (male 16, female 14). Among the measurements we assessed, 29 linear measurements
showed significant correlations with the CBL. In the standardized major axis regressions using thesemeasurements, three measurements showed significant differences of slopes between sexes. This indicates thatnasal length, zygomatic length, and mandibular depth of female are more strongly affected by the skull size
variation. Nine measurements showed significantly different elevations between sexes. This indicates that female
possesses relatively larger neurocranium and wider rostrum. Differences of allometric trajectories between sexes
suggest that female is not simply a dwarf morph of male and imply that remarkable sexual difference of
ontogenetic patterns (growth duration and speed of each skull component) reflects intersexual differences of life
history strategies.

   Testing heterochrony for dietary adaptations in skull morphology of canids
Masakazu Asahara1Masaharu Motokawa2
Graduate School of Sciences, Kyoto University1Kyoto University Museum, Kyoto University2
During ontogeny in canids (Canidae, Carnivora), skull shapes were changed from brachycephalic (with smaller
snout) to dolichocephalic (with larger snout). Similar morphological variation exists as a result of dietaryadaptations among whole Carnivora. That is, carnivorous species have brachycephalic skulls and omnivorous
species have dolichocephalic skulls. Thus, we could hypothesize that such variation in skull morphology was
resulted from heterochronic evolution. To test this hypothesis, we compared skull morphology of canids
including juveniles and adults using three-dimensional geometric morphometrics and several measurements.
Then, ontogenetic trajectories were compared among species. We found some cases of large carnivorous species
could be interpreted to heterochronic evolution as progenesis in shape. However, ontogenetic trajectories of skull
shapes largely varied and thus simple heterochronic evolution as progenesis or hypermorphosis could not explain
for most variations of skull shape in canids. On the other hand, size of the snout shared similar ontogenetic
allometric lines among species and thus size of snout is adaptable to heterochronic explanation. However
allometric lines of lengths constituting proportion of snout varied among species. Our results raised conflict
between size and shape morphogenesis and inferred that heterochrony is mainly important for size
morphogenesis.
   Allometry of masticatory muscles of the order Carnivora

Department of Earth and Planetary Science, The University of Tokyo1, The University Museum, The
University of Tokyo2
Carnivora has been focused on its mastication by the dental morphology and the morphometrics of its skull. On
the other hand, myological approaches have not been carried out enough. This study conducts the gross anatomyof the four masticatory muscles (masseter, temporalis, medial and lateral pterigoid) in the 18 species ofcarnivores to examine the relationships between the muscle mass and the fascicle length. In the double
logarithmic plot (x-axls: the fascicle length, y-axls: the muscle mass), the masseter and temporalis, the main
generators of bite force, were highly correlated. The former: y=2.879x+0.419, R2=0.941, the latter:y=2.940x+0.507, R2=0.926. The growth of the two muscles showed an isometric trend, and was not influenced
by phylogenetical status and feeding behaviors in each species. The results suggest that the bite force ofcarnivora may be determined by fascicle length rather than the muscle shape at least in the masseter andtemporalis.

   Morphological diversity and functional significance of the ossicles among
lipotyphlans

Misato Hosojima1Daisuke Koyabu2Hideki Endo1
The University Museum, The University of Tokyo 1, The Kyoto University Museum2
Considerable interspecific morphological variations are observed in the auditory ossicles among mammals. The
low-frequency sound is the most dominant in the underground environment, and the subterranean species use
low-frequency sound for auditory perception. In this study, we hypothesized that the patterns of morphologicaldiversity in the ossicles is influenced by variation in lifestyles. To test this hypothesis, we morphologicallycompared the ossicles among the lipotyphlan species which include various lifestyles, such as terrestrial,semi-subterranean, and subterranean. We conducted 3D reconstructions of micro CT images of the ossicles forone species of hedgehogs, seven species of shrews, one species of solenodons, and six species of moles. Then,linear traits and surface areas were compared among species. The ratios of malleus lever arm against incus leverarm were lower in the order of subterranean, semi-subterranean, and terrestrial lifestyle. In contrast, thestapes-footplate areas were larger in the order of subterranean, semi-subterranean, terrestrial lifestyle. In addition,
the malleus/incus lever ratios and stapes-footplate areas were not correlated with phylogenetic relatedness. It has
been known that reduced malleus/incus lever arm ratio and enlarged stapes-footplate areas can efficiently
transmit low-frequency sound. Therefore, we suggested that the morphological diversity in the ossicles may be
evolutionarily correlated to the variation in lifestyles among liphotyphlan species.
   Heterochrony of cranial ossification sequence in Boreoeutherian mammals

The Kyoto University Museum1, Paleontological Institute and Museum, University of Zürich2, The University
Museum, The University of Tokyo3
To investigate the role of ontogenesis in producing adult morphological diversity, the mostcomprehensive analysis to date on osteogenesis of 22 cranial elements in 42 species of mammals was conducted,
spanning over nine orders. Results demonstrate that mammals are characterized by the delayed onset ofpterygoid relative to other bones compared to the sauropsid outgroups. Given the evolutionary fact that thepterygoid bone has experienced a relative size reduction in mammals from the condition of early synapsids, wesuggest that the late shift of the pterygoid is linked to the evolutionary reduction of this bone in mammals. In
addition, we find that moles are characterized by the extremely early development of the bones that constitutethe vomeronasal complex (nasal, vomer, palatine, frontal, and pterygoid). Since the vomeronasal complex isrelatively robust compared to those of the moles’ close relatives (shrews and hedgehogs) and plays an importantrole in fossorial lifestyle, we suggest that the early developmental shift of vomeronasal bones in moles reflects
their functional emphasis on this morphological complex. We also detect a pattern of step-by-step early shifts of
the occipital bones in human evolution. Basioccipital moves earlier in Euarchontoglires, supraoccipital shifts
earlier in Primates, exoccipital moves earlier in Catarrhini, and exoccipital shifts further earlier in Homo sapiens.
As these bones have been proportionally enlarged in the human lineage, the gradual acceleration of occipitalbone development may be linked to evolutionary expansion of these bones. Our comprehensive study on cranial
ossification sequence reveals that numerous sequence heterochronies have occurred along the evolution of
mammals and suggests that shifts in developmental program may reflect evolutionary changes in life histories.

   Elbow extensor, flexor, and adductor moment arms as an indicator of forelimb
posture and scansorial ability in quadrupedal tetrapods

Shin-ichi Fujiwara1,2John R. Hutchinson2
The University Museum, The University of Tokyo1Royal Veterinary College2
Forelimb postures (e.g., sprawling and sagittal) and scansorial abilities have dramatically diversified in thetetrapod lineage. But the skeletal morphologies that indicate either posture or locomotor abilities are not wellunderstood. Hence, forelimb postures of some extinct taxa (e.g., desmostylian mammals) have beenreconstructed in different ways among researchers. Here we report a new forelimb posture indicator which isapplicable to a majority of extant tetrapods. First, the degree of elbow joint adduction/abduction mobility wasdetermined in some lizard specimens. This step revealed that the carpal flexors also function as elbow“adductors”, which may play a major role during the stance phase in sprawling postures (e.g., toads, monotremes,moles, lizards). This function is different from sagittal and creeping (against surface friction: e.g., sloths) limb
postures which respectively depend more on elbow extensors and flexors for propulsion. Measurements of elbow
muscle moment arms in 313 extant tetrapod skeletons (Anura, Testudines, Lepidosauromorpha, Crocodilia, Aves,
and Mammalia: 32 orders, 122 families, and 259 genera) revealed that sprawling, sagittal, and creeping tetrapods
respectively emphasize elbow adductor, extensor, and flexor muscle functions over others. Furthermore,scansorial taxa possess relatively larger elbow flexor moment arms than non-scansorials. Therefore, forelimb
postures of extinct tetrapods can be reconstructed based on our new quantitative index. Desmostylian mammals
are categorized as sagittal non-scansorials based on this indicator.   Macroscopic observation of male and female reproductive organ in Koreanwater deer (Hydropotes inermis)

College of Veterinary Medicine, Seoul National University, Seoul, Korea1,
College of Physiology, Development and Neuroscience, University of Cambridge, UK2The water deer is known to be an endemic species in Korea and some limited areas in East China andSouth-eastern part of England. There have been no studies of their basic reproduction. To understandthe reproductive strategy of this species, their male and female reproductive organs were anatomicallyobserved. The ampulla of deferent duct, vesicular gland, prostate gland (body and diffuse part) andbulbourethral gland were identified. Their shape, location and structure were basically similar to that ofgoat and sheep like small ruminants. The existence of the spermatozoon was histologically confirmed in
the lumen of the convoluted seminiferous tubule of individuals obtained on late October to December.
Spermatogenesis might take place in specific periods. The uterus was categorized as a bicornuate uterus.
The placentomes existed in the whole uterine horns and numbered 6. The volume of each cotyledon
was 16-17cm3. The shape of the placentome was convex. The placenta can be classified as anoligocotyledonary placenta. The number of fetus is 2-4 and is exceptionally larger than in otherruminant species. Although the number of placentomes is similar to other cervidae species, there might
be some special mechanism or structure in the attachment site of the fetus to accommodate an
extraordinary number of fetuses in the water deer. These results may contribute to the management andconservation of this species.

Two karyotype races of the greater Japanese shrew-mole (Urotrichus talpoides) are known to occur on Honshu,with the boundary being found along the Kurobe-Fuji line. We conducted the first study of geographic variationin cranial morphology to test whether chromosomal variation patterns were reflected in morphological data andto quantify geographic shape variation. In total, 174 shrew-moles were analysed using landmark- andoutline-based geometric morphometric methods. Results indicate ventral and dorsal cranial morphology differed
between shrew-moles from western and eastern Honshu, in agreement with chromosome variation boundaries.
Inclusion of other island populations revealed differences between shrew-moles in Kyushu, Tsushima and North
Honshu. Shrew-moles from Tsushima and North Honshu have a progressively more elongated zygomatic archand lengthened rostrum compared with those from Kyushu. For the dentary, geographic separation was greatest
for the coronoid process. Shrew-moles from eastern Honshu are characterised by a coronoid process with ashorter anterior margin and slightly broader tip compared to western Honshu populations.   CRANIOMETRIC VARIATION AMONG THE RACCOON DOG

The raccoon dog, Nyctereutes procyonoides, is an endemic species in East Asia but can be found as far as
Europe after being introduced from eastern part of Russia about 70 years ago. Currently this species is divided
into six subspecies depending geographic distribution. Recent studies have proposed that Japanese raccoon dogs
should be classified as a distinct species from other subspecies because of its unique chromosome number.
However, since there have been few studies using molecular markers and morphological characters,
geographical variation among all raccoon dog populations remain unclear. To clarify the morphological variation
among raccoon dog populations, we examined 480 skulls consisting of five subspecies from seven locations:Korea, Honshu, Shikoku, and Hokkaido in Japan, Northern China, East Russia and Finland. Our results indicatedthat Finnish raccoon dogs possessed substantially different shape of skull and teeth by validity of Bergmann’srule. Variation analysis also showed that Hokkaido populations were significantly different from otherpopulations within the Japanese raccoon dogs and this might be affected by isolation by Blakistone’s line. We
insist that Bergmann’s rule could be one of the influential factors affecting the skull morphology of the Finnish
and Hokkaido populations. This study suggests the revaluation of the taxonomic status of these subspecies andmanagement of raccoon dogs. Extension of morphological studies will also be necessary to confirm of theseinterpretations.

Genetic status and the origin of the sable Martes zibellina (Carnivora, Mustelidae) in Hokkaido was evaluated bycomparing the genetic diversity of populations in Russian Far East and Hokkadio, using nucleotide sequences ofthe mitochondrial NADH dehydrogenase subunit 2 gene (976 base pairs). Molecular phylogenetic (Maximum
likelihood and Bayesian inference approaches) and network (Median joining method) analyses recovered themonophyly of the sables originated from Hokkaido. Bayesian-relaxed molecular clock dating approach estimatedthe date for the migration of sables into Hokkaido to lie between 0.10 and 0.27 million years before present.
Taking into account the geological evidence that Hokkaido was not connected to the other Japanese islands but
to Eurasian continent in the Late Pleistocene period and that the sables have not been found on the Japaneseislands other than Hokkaido, the Late Pleistocene period was supposed to be the most plausible epoch for theestablishment of the sable in Hokkaido. Lower genetic diversity of the Hokkaido population of the sable
observed in this study was probably caused by the founder effect in the establishment of the sable population on
the island or excessive hunting by humans for fur industry. We further discuss the genetic diversity of
populations in Russian Far East and mammalian faunal constructions in Hokkaido.

Gorals (Naemorhedus species) and Serows (Capricornis species) are closely related species in the tribe Caprini.
In order to investigate the patterns of variation across the control region domains of mitochondria, a study on thecomparative analysis both within and between species was accomplished. Complete sequences of themitochondrial control region (1031-1212 nt) from 73 specimens of 5 species (2 Naemorhedus species, 2Capricornis species, 1 Capra hircus) were aligned and analyzed. A total of 15 haplotypes from N. caudatus, 1
from N. goral, 8 from Capra hircus, 2 from C. swinhoei, and 27 from C. crispus were tested for reconstructing
the phylogenetic tree. Based on comparative analysis of control region sequences of five species for the present
study, we also found three distinct domains as described firstly by Sbisa (1997): ETAS, central, and CSB domain.
As base composition of three domains, A+T<G+C was found. Three tandem repeats (about 76 nt) were found inleft domain of control region of N. caudatus and N. goral, while two tandem-repeated sequences were identified
in C. crispus and Capra hircus. CSB-1 and polypyrimidine tract were also represented and showed homologous
region compared with other domains. In the aligned sequences of tandem repeats, two pairs of mirror symmetry
sequences (TACAT, ATGTA) were found. The phylogenetic inference by complete sequence of control region
implied that Naemorhedus and Capricornis had distinct clade as a different genus, concordant with the findings
previously described by cytochrome b.

Understanding the correct population subdivision and extent of genetic divergence among populations is decisivefor development of efficient management and conservation plan. Using two different kinds of genetic markers,
mitochondrial DNA (mtDNA) and microsatellite loci, we evaluated population genetic structure of Eurasian red
squirrels collected from Russia, China, Mongolia, and South Korea. The mtDNA data showed gene genealogies
of S. vulgaris are not structured while microsatellites outcomes indicated three population genetic structures
according to geographic affiliation. In particular, the star-like pattern and low genetic variation were observed
from mtDNA. The discrepancy of results between mtDNA and microsatellite loci could be caused by several
factors such as sex-biased dispersal, differences in refugial effective population size, or time frame differenceeach genetic marker showed. We will think about which factors result in this contrasting population genetic
structure of S. vulgaris.
