CONTEXT AND CONTENT. Content as for genus. Distinctions among H. malayanus, H. euryspilus, and H. anmamiticus are contested (Pocock 1932). H. malayanus was split into 2 subspecies, H. m. malayanus and H. m. euryspilus, on the basis of size differences (Chasen 1940; Santiapillai and Santiapillai 1988). However, genetic variability is unknown (Zhang 1996), and we consider H. malayanus monotypic. 

Tremarctos ornatus (Carnivora: Ursidae)

Abstract: Tremarctos ornatus (F.G. Cuvier, 1825) is a tremarctine bear commonly known as the Andean bear. It is a medium-sized bear with black to dark red-brown pelage with dense, long, coarse fur;

ORIGINAL ARTICLE: Mammals of Borneo – small size on a large island

Whether Borneo is characterized by smaller mammals than adjacent areas, and possible causes for the different trajectories of size evolution between different Bornean species are examined.

Ecomorphological correlates of craniodental variation in bears and paleobiological implications for extinct taxa: an approach based on geometric morphometrics

Results reveal a set of shared craniodental traits among the herbivorous bears, including short and vaulted skulls with well-developed zygomatic arches, lateralized orbits and small canines, concave jaws with a highly positioned condyle, large moment arms for the temporalis and masseter muscles, and long cheek teeth.

Possible Male Infanticide in Wild Orangutans and a Re-evaluation of Infanticide Risk

It is suggested that in orangutans, and other species where nulliparous females are not preferred mates, these females may be less successful at using paternity confusion as an infanticide avoidance tactic, thus increasing the likelihood of infanticides of their first-born infants.

ENAMEL STRUCTURE OF ARCTOID CARNIVORA: AMPHICYONIDAE, URSIDAE, PROCYONIDAE, AND MUSTELIDAE

  • C. Stefen

  • 2001
Enamel of several fossil and recent arctoid carnivores was studied with light and scanning electron microscopy and the hypothesis that zigzag HSB evolved multiple times to resist cracking of the enamel under high tensile stress was supported.

Mammalian Hybrids and Generic Limits

A survey of reported mammalian intergeneric hybrids and the application of reproductive criteria to the definition of the category of genus led to the recommendation of a number of taxonomic changes in the content of genera.

STUDIES ON MALAYAN SUN EEAR(HELARCTOS MALAYANl/S)IN ARTIFICIAL REARING

From September 1987 to August 1989, the authors had reared Malayan Sun Bears, 2 male adults and 7 subadults (3 , 4 ) which were from Ruili, west of Yunnan Province, studied the composition of diet

A comparative chromosome banding analysis of the Ursidae and their relationship to other carnivores.

A comprehensive analysis of the homologous banding patterns within the Ursidae and with a hypothesized ancestral carnivore karyotype permitted the reconstruction of three significant chromosomal reorganization events that occurred during the evolution of the modern ursids.

Genetic Variability and Conservation Relevance of The Sun Bear As Revealed by DNA Sequences

The results suggest that the mitochondrial D-loop region is very useful for population genetic study of the sun bear and compares with the black rhino Trna genes.

A phylogeny of the bears (Ursidae) inferred from complete sequences of three mitochondrial genes.

Calibration of the corrected average number of nucleotide differences per site with the fossil record indicates that transitions at third positions of codons in the ursid cytochrome b gene occur at a rate of approximately 6% per million years, which is considerably slower than comparable values reported for other species of mammal.

Phylogenetic relationships of bears (the Ursidae) inferred from mitochondrial DNA sequences.

Analysis of mitochondrial DNA sequences from all bear species and the giant panda suggests that relative substitutional rates between different mitochondrial DNA regions may vary greatly among different taxa of the vertebrates.

MOLECULAR GENETIC‐DISTANCE ESTIMATES AMONG THE URSIDAE AS INDICATED BY ONE‐ AND TWO‐DIMENSIONAL PROTEIN ELECTROPHORESIS

The topological concordance of the data sets from one‐ and two‐dimensional electrophoresis supports the usefulness of these procedures for evolutionary inference and provides additional precision to the reconstruction of divergence nodes of this carnivore group.
