The stumptail macaque species Macaca thibetana and Macaca arctoides replace one another from north to south in subtropical and tropical China. These species differ in external and cranial characters. Neonatal pelage color is pale grayish-brown in M. thibetana and whitish in M. arctoides. In adults, ventral pelage is whitish in M. thibetana and brown in M. arctoides. The forehead and cheeks are thickly furred in adult M. thibetana and bald in M. arctoides. Facial skin color typically is sexually dimorphic in M. thibetana—buffy in males and reddish in females—and monomorphic in M. arctoides—reddish in both sexes. Head and body length, weight, relative tail length, and relative ear length all tend to average greater in M. thibetana than in M. arctoides. Skull length, rostral-postrostral ratio, and relative canine length in males average greater in M. thibetana. than in M. arctoides; relative zygomatic breadth and relative bimalar breadth average greater in M. arctoides than in M. thibetana. Reproductive anatomy in both sexes is strikingly divergent in these two species. Although these species are adapted to different climatic zones, many aspects of their natural history are generally similar, as far as is now known. One apparent behavioral difference is that M. thibetana usually sleeps in caves or rocky crevices, while M. arctoides usually sleeps in trees.  相似文献

To study the phylogenetic relationships of the macaques, five gene fragments were sequenced from 40 individuals of eight species: Macaca mulatta, M. cyclopis, M. fascicularis, M. arctoides, M. assamensis, M. thibetana, M. silenus, and M. leonina. In addition, sequences of M. sylvanus were obtained from Genbank. A baboon was used as the outgroup. The phylogenetic trees were constructed using maximum-parsimony and Bayesian methods. Because five gene fragments were from the mitochondrial genome and were inherited as a single entity without recombination, we combined the five genes into a single analysis. The parsimony bootstrap proportions we obtained were higher than those from earlier studies based on the combined mtDNA dataset. Excluding M. arctoides, our results are generally consistent with the classification of Delson (1980). Our phylogenetic analyses agree with earlier studies suggesting that the mitochondrial lineages of M. arctoides share a close evolutionary relationship with the mitochondrial lineages of the fascicularis group of macaques (and M. fascicularis, specifically). M. mulatta (with respect to M. cyclopis), M. assamensis assamensis (with respect to M. thibetana), and M. leonina (with respect to M. silenus) are paraphyletic based on our analysis of mitochondrial genes.  相似文献

Taxonomic status and type specimens of Platycephalus bataviensis Bleeker 1853, described based on two syntypes (110 and 140 mm TL) from Batavia (= Jakarta), are discussed. Four platycephalid specimens have been recognized as possible syntype(s) of P. bataviensis. Of them, a specimen of 140.5 mm TL deposited at Muséum National d’Histoire Naturelle, Paris, identified as Inegocia japonica, is regarded to be the larger syntype and is designated as the lectotype of P. bataviensis in this study, while the paralectotype of the species is not identified. As a result, P. bataviensis becomes a junior synonym of I. japonica.  相似文献

As a first step in reviewing the classification of the two stump-tailed macaque species,Macaca arctoides andM. thibetana, as compared with other species of the genusMacaca, 72 linear dental and cranial variables of 11 macaque species were examined by morphometric analyses. The results indicate that the two stump-tailed species are the largest of the macaques and although rather similar overall, they exhibit significant differences in the pattern of variation in most of the five skull regions as shown by Principal Components and Canonical Variate Analyses. Euclidean Distances based on Canonical Variate scores indicate that the females ofM. arctoides andM. thibetana are more widely separated than eight other pairs of macaque species, and that the separations of the respective males are greater than those of three other pairs of species. These findings are consistent withFooden's classification of the stump-tailed macaques as two separate species (Fooden, 1976;Fooden et al., 1985). The present results suggest, as other researchers have proposed on the basis of external features, biochemistry and genetics, that the two stump-tailed macaque species andM. assamensis are closely related. The results also tentatively imply associations withM. fuscata andM. sylvanus but these require further study. The findings have implications for the assessment of the various Chinese Pleistocene macaque fossils.  相似文献

Tibetan macaques (Macaca thibetana), stump-tailed macaques (M. arctoides), Assamese macaques (M. assamensis), and northern pig-tailed macaques (M. leonina) are four major species of Macaca in China. In order to effectively use these species in biomedical research, thorough investigations of their MHC immunogenetics are required. In this study, we identified MHC class I sequences using cDNA cloning and sequencing on a cohort of six M. thibetana, three M. arctoides, three M. assamensis, and three M. leonina derived from Sichuan and Yunnan provinces of China. Eighty new alleles were identified, including 26 MHC-A alleles, 46 MHC-B alleles, and 8 MHC-I alleles. Among them, Math-A1*126:01, Math-B*190:01, Math-B*191:01, Math-B*192:01, Maar-A1*127:01, Maar-A1*129:01, and Maas-A1*128:01 represent lineages that had not been reported earlier in Macaca. Phylogenetic analyses show that no obvious separation of lineages among these species of Macaca. This study provides important information about the MHC immunogenetics for the four major species of Chinese macaques and adds value to these species as model organisms in biomedical research.  相似文献

Study of ten females ofMacaca assamensis provides information concerning reproductive anatomy, postnatal development and systematic relationships of this species. The sexual skin is conspicuously inflated in adolescentM. assamensis; during pregnancy smaller sexual swellings are present; during lactation the sexual skin is uninflated and marked by a sharply defined dark blue circumanal triangle. In the vulva of infant and adolescentM. assamensis a ventral vestibular fold protrudes between the vaginal orifice and the recessed urethral orifice; in postadolescent specimens the ventral vestibular fold is absent and a urethral papilla is present. The lining of the vagina is spiny in prepregnantM. assamensis and rugose to papillate in other phases of the cycle. The cervix is greatly enlarged and secretory in adolescentM. assamensis; it remains large before and during pregnancy and becomes constricted during lactation. The cervix inM. assamensis is similar to that inM. sinica andM. radiata. This supports previously reported penial evidence of close relationship between these species. Penial structure inM. thibetana indicates that this species also belongs to thesinica-radiata-assamensis group. In these four species latitudinal variation of body size and tail length apparently conforms toBergmann's rule andAllen's rule.  相似文献

The original collections of Cystoseira algeriensis J. Feldmann and of Cystoseira elegans Sauvageau, both held in the Herbarium of the Laboratoire de Cryptogamie, Muséum National d'Histoire Naturelle (PC), were examined and lectotypes were designated, since no holotypes were indicated by original authors.  相似文献

Macaca, comprising 20 well-characterized species, represents the largest and one of the most ecologically and socially diverse of all the nonhuman primate genera. We report the discovery of a macaque that is new to science from the high altitudes of western Arunachal Pradesh, a biodiversity-rich state in northeastern India. We propose the scientific name Macaca munzala and the vernacular name Arunachal macaque for the species. It shares morphological characteristics independently with the Assamese macaque (Macaca assamensis) and with the Tibetan macaque M. thibetana; like them, it appears to belong to the sinica species-group of the genus. However, the species is distinctive in relative tail length, which is intermediate between those of Tibetan and Western Assamese macaques, the subspecies with which it is sympatric. It is also unique in its altitudinal distribution, occurring largely at altitudes between 2000 and 3500 m. We provide a morphological characterization of the species, report preliminary data on its field biology and discuss possible taxonomic identity in relation to the other closely-related species of Macaca.*This paper is dedicated to Dr. A. J. T. Johnsingh for his immense contributions to the study and conservation of India’s wildlife and for being an inspiration to a whole generation of students.  相似文献

The distributions of Assamese macaques (Macaca assamensis) and rhesus macaques (M. mulatta) in Bhutan have been only partially documented. In order to investigate the distribution patterns of these species, we conducted field observation and genetic assessment with mitochondrial DNA (mtDNA) typing of macaques in the Inner Himalayas of Bhutan. There were 24 sightings of macaque groups, and all were visually identified as Assamese macaques. No groups of rhesus macaques were sighted in this survey area, in contrast with the survey results in the Nepalese Himalayas. Molecular phylogenetic analysis revealed that the Bhutan macaques are closer in proximity to their counterparts in the Indo-Chinese region (Thailand and Laos) than to rhesus macaques in China, Laos and India. However, clustering results suggested the marked differentiation of the macaques in Bhutan from the Assamese macaques in Indo-China. We tentatively conclude that the macaques of the Inner Himalayan regions in Bhutan are Assamese macaques and that they appear to be of a lineage distinct from Assamese macaques in the Indo-Chinese region (subspecies M. a. assamensis). The degree of mtDNA diversity suggests that the Assamese macaques in Bhutan are of a more ancient ancestry than M. a. assamensis, thereby supporting the speciation hypothesis of the expansion of a sinica-group of macaques from South Asia to Southeast and then to East Asia (Fooden; Fieldiana Zool 45:1–44, 1988). Assignment of Assamese macaques in Bhutan to M. a. pelops is premature due to the lack of molecular data and recent taxonomic controversy. The mtDNA diversity of Assamese macaques was greater than that of rhesus macaques, suggesting the earlier speciation of Assamese macaques. The significance of the ecogeographic segregation model of macaque distribution is discussed in relation to the evolutionary range expansion into the Himalayan regions in South Asia.  相似文献

Serum albumin (Alb) and erythrocyte adenosine deaminase (ADA) polymorphisms in Asian macaques were investigated by means of starch gel electrophoresis. The materials comprise a total of 2,323 blood samples from eight species, namely,Macaca fuscata,M. mulatta,M. cyclopis,M. fascicularis,M. nemestrina,M. speciosa,M. radiata, andM. assamensis. It was observed that three Alb phenotypes were controlled by two codominant alleles, Alb mac A and Alb mac B and six ADA phenotypes by four codominant alleles, ADA mac 1 , ADA mac 2 , ADA mac 3 , and ADA mac 4 . The taxonomic relationships amongM. assamensis,M. radiata, andM. mulatta were analyzed by measuring theNei's (1975) genetic distance. The result supportedHill andBernstein's (1969) postulation thatM. assamensis was more closely related phylogenetically toM. radiata than toM. mulatta.  相似文献

The original collection of Aspidophora gaudichaudii Montagne was located in the Herbarium of the Laboratoire de Cryptogamie, Muséum National d'Histoire Naturelle (PC), and examined. An earlier report that the peltate, shield-like structures scattered over the lower surface of the blade surface were merely multicellular peglike rhizoidal attachments and not cystocarps was confirmed. The even earlier described Aglaophyllum peltatum Montagne has been found to be the same as Aspidophora gaudichaudii. Morphological evidence points to the identity of both Aspidophora gaudichaudii and Aglaophyllum peltatum with Cryptopleura corallinarum (Nott) Gardner. Because the name Aglaophyllum peltatum has priority, the binomial Cryptopleura peltata (Montagne) M. J. Wynne comb. nov. is proposed.  相似文献

We cross-sectionally investigated prenatal ontogeny of craniofacial shape in the two subspecies of the Japanese macaque (Macaca fuscata fuscata and Macaca fuscata yakui) using a geometric morphometric technique to explore the process of morphogenetic divergence leading to the adult morphological difference between the subspecies. The sample comprised a total of 32 formalin-fixed fetal specimens of the two subspecies, in approximately the second and third trimesters. Each fetal cranium was scanned using computed tomography to generate a three-dimensional surface model, and 68 landmarks were digitized on the external and internal surface of each cranium to trace the growth-related changes in craniofacial shape of the two subspecies. The results of our study demonstrated that the two subspecies generally shared the same craniofacial growth pattern. Both crania tend to exhibit relative contraction of the neurocranium in the mediolateral and superoinferior directions, a more superiorly positioned cranial base, a more vertically oriented occipital squama, and a more anteriorly positioned viscerocranium as the cranial size increased. However, distinctive subspecific differences, for example relatively narrower orbital breadth, higher orbit, higher position of the nuchal crest, and more protrudent snout found in Macaca fuscata yakui were already present during the prenatal period. This study demonstrated that morphological differentiation in the craniofacial shape may occur at a very early stage of the fetal period even between closely related subspecies of the Japanese macaque.  相似文献

Sinha, A., Datta, A., Madhusudan, M. D., & Mishra, C. (2005. Macaca munzala: A new species from western Arunachal Pradesh, northeastern India. International Journal of Primatology, 26, 977989) discovered Arunachal macaques (Macaca munzala), a species new to science, in the eastern Himalaya of Arunachal Pradesh in northeastern India. They depicted the holotype and paratypes of the species in photographs, and a specimen of the species had been unavailable for preservation and examination. In March 2005, we obtained an entire specimen of an adult male Macaca munzala, which we propose as a voucher specimen for the species. We provide detailed morphological and anatomical measurements of the specimen and examine its affinities with other macaques. Macaca munzala appears to be unique among macaques in craniodental size and structure, baculum, and aspects of caudal structure, while exhibiting affinities with the other members of the sinica-group to which it belongs. We summarize our insights on the origins and phylogeny of Macaca munzala. Finally, we review the current conservation status of the macaques, which are threatened by extensive hunting in the only 2 districts of Arunachal Pradesh where they are documented to occur.  相似文献

Crocodyloid remains from the late Paleocene of Mont de Berru (France) hosted in the collections of the Muséum National d’Histoire Naturelle (Paris, France) and in the Institut royal des Sciences naturelles de Belgique (Brussels, Belgium) are described for the first time. This material, although fragmentary, can be clearly referred on a morphological basis to Asiatosuchus depressifrons (Blainville, 1855), a species previously reported from several Eocene Belgian localities thanks to abundant material including a nearly complete skeleton. The Paleocene material shares with A. depressifrons the number of alveoli involved in the dentary symphysis, the exclusion of the splenials from the symphysis, and the presence of a distinct depression on the jugal. The fossil remains from Berru represent the oldest European crocodyloid. Along with the alligatoroid Diplocynodon remensis Martin, Smith, de Lapparent de Broin, Escuillié and Delfino, 2014, previously reported from the same locality, the crocodyloid A. depressifrons indicates that these genera reached Europe before the Paleocene–Eocene Thermal Maximum. Although more complete remains from outside Europe are needed to refine phylogenetic hypotheses, according to the currently established fossil record the forerunners of diplocynodontids likely dispersed from North America, whereas those related to Asiatosuchus likely dispersed from Asia.  相似文献

From the end of 1830, Étienne Geoffroy Saint-Hilaire worked to prepare a book on thalattosuchians (Mesoeucrocodylia, Thalattosuchia) from the Jurassic of Normandy. This work, planned to be entitled “Histoire des crocodiliens renfermés dans le terrain oolithique”, was never completed. Searches in the archives of the central library of the “Muséum national d’histoire naturelle”, Paris, resulted in the rediscovery of the set of original drawings ordered by Geoffroy Saint-Hilaire to illustrate his book. These drawings, 21 in total, were executed by several artists working in the Muséum, including Jean-Charles Werner, Henri-Joseph Redouté, and Nicolas Hüet. Geoffroy Saint-Hilaire offered this collection of drawings to the French Academy of Sciences in March 1834. These drawings were then donated to the library of the Muséum in November 1924 by Alfred Lacroix. This iconographic collection is of the highest importance for the history of palaeontology in France as it depicts unknown specimens that were destroyed during World War II.  相似文献

Stump-tailed macaques (Macaca arctoides) exhibit significant intraspecific variation in pelage color. Based on their pelage color and geographical distribution, they are classified into 2 subspecies: northern bright brown Macaca arctoides arctoides and southern black Macaca arctoides melanota. However, studies on the natural population are extremely scarce, and researchers have occasionally questioned the subspecific classification. We quantitatively examined pelage color variation of Macaca arctoides in 3 free-ranging populations in Thailand. Pelage color difference between populations is significant. The population distributed south of the Isthmus of Kra showed wide intrapopulational variation, including bright brown, dark brown, and completely black, whereas the northern populations primarily had dark brown hairs. Thus, we conclude that one cannot classify the color variants into subspecies. Further, we hypothesize that the distinctive polymorphism in southern Thailand resulted from geographical isolation caused by the Pleistocene eustatic fluctuations and subsequent recovery of land connection and subsequent gene flow.  相似文献
