Dental shape evolution of the giant panda (Ailuropoda, Ursidae) during the Quaternary

Historical Biology
The giant panda is well known to have unique dentition, adapted to bamboo exclusive diet. The teeth are used to cut and grind the bamboo. However, it is unclear how these teeth evolved through geographical time.

Genetics of the Andean bear (Tremarctos ornatus; Ursidae, Carnivora) in Ecuador: when the Andean Cordilleras are not an Obstacle

Mitochondrial DNA. Part A, DNA mapping, sequencing, and analysis, 2020
One of the top carnivores in the Andean mountains is the Andean bear (Tremarctos ornatus, Ursidae), the only bear in South America. This is a flagship and key umbrella species in Ecuador because its conservation has a positive impact on the conservation ...

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

Cytogenetics and Cell Genetics, 2008
Trypsin G-banded karyotypes of eight species of Ursidae were prepared from retrovirus-transformed skin fibroblast cultures. The banding patterns of all bears are highly conserved, even though their diploid numbers range from 42 to 72. A comprehensive analysis of the homologous banding patterns within the Ursidae and with a hypothesized ancestral ...

Ecomorphological indicators of feeding behaviour in the bears (Carnivora: Ursidae)

Journal of Zoology, 2004
AbstractPatterns of morphological variation in the skulls of extant bears were studied as they relate to diet and feeding behaviour. Measurements of craniodental features were used to compute indices that reflect dietary adaptations of the dentition and biomechanical properties of the skull, jaw and related musculature.

Basic haematological values in carnivores—I. The canidae, the hyaenidae and the ursidae

Comparative Biochemistry and Physiology Part A: Physiology, 1987
Basic haematological values for 32 animals of four carnivore species are reported. In six adult wolves (Canis lupus) the mean values estimated for the erythrocyte count 7.48 X 10(12)/l, haematocrit 0.465/l, haemoglobin 172.0 g/l and leukocyte counts 7.33 X 10(9)/l are given.

Further morphological features, molecular characterization, and Wolbachia endosymbionts of Dirofilaria ursi Yamaguti, 1941 (Spirurida: Onchocercidae) from the Japanese black bear Ursus thibetanus japonicus Schlegel (Carnivora: Ursidae).

Acta Tropica
Dirofilaria ursi Yamaguti, 1941 (Spirurida: Onchocercidae) was originally described from the Japanese black bear Ursus thibetanus japonicus and later reported from the American black bear U. americanus in North America. Both D. ursi and D.
