Procapra przewalskii (Büchner, 1891), commonly called Przewalski’s gazelle, is polytypic with 1 of the 2 subspecies (P. p. diversicornis) likely extinct. The species now occurs only in the Qinghai Lake region in northeastern Qinghai Province, western China, and predominately inhabits semiarid grassland steppe, stable sand dunes, and the desert–shrub ecotone between them. Numbers and distributio...
Procapra picticaudata Hodgson, 1846, is commonly called the Tibetan gazelle, goa (5 Tibetan), or zang yuan ling (5 Chinese) and is monotypic. It is a high-elevation specialist endemic to the Tibetan Plateau where it prefers alpine meadow and alpine steppe but uses other lower-elevation plains and valleys. It is partial to good grasslands with high diversity of forbs. There have been no systemat...
In this article, we examine the possible contribution of behavioural studies to the determination of phylogenetic relationships within the Bovidae. First, we revisit the general arguments concerning the use of behavioural traits as phylogenetic characters; then we present our first attempt at reconstructing the phylogeny of Bovidae based on behavioural data taken from the literature. Despite th...
We investigated the utility of diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) for the analysis and identification of sea turtle (Family Cheloniidae) and bovid (Family Bovidae) keratins, commonly used to manufacture historic artefacts. Spectral libraries are helpful in determining the class of the material (i.e., keratin versus plastics), but do not allow for inferences abo...
The Pecorans (higher ruminants) are believed to have rapidly speciated in the Mid-Eocene, resulting in five distinct extant families: Antilocapridae, Giraffidae, Moschidae, Cervidae, and Bovidae. Due to the rapid radiation, the Pecoran phylogeny has proven difficult to resolve, and 11 of the 15 possible rooted phylogenies describing ancestral relationships among the Antilocapridae, Giraffidae, ...
This paper reports the investigation of risk factors for bovine herpesvirus-1-seropositivity, based on a cluster-sample survey of the Belgian cattle population. This serosurvey was carried out in 1998 in 309 randomly selected unvaccinated herds of all types (dairy, mixed and beef) were all bovids (N = 11,284) were sampled. Older and male cattle had higher seroprevalence. Origin (homebred or pur...
