Managers of threatened species often face the dilemma of whether to keep populations separate to conserve local adaptations and minimize the risk of outbreeding, or whether to manage populations jointly to reduce loss of genetic diversity and minimise inbreeding. In this study we examine genetic relatedness and diversity in three of the five last remaining wild populations of dama gazelle and a number of captive populations, using mtDNA control region and cytochrome b data. Despite the sampled populations belonging to the three putative subspecies, which are delineated according to phenotypes and geographical location, we find limited evidence for phylogeographical structure within the data and no genetic support for the putative subspecies. In the light of these data we discuss the relevance of inbreeding depression, outbreeding depression, adaptive variation, genetic drift, and phenotypic variation to the conservation of the dama gazelle and make some recommendations for its future conservation management. The genetic data suggest that the best conservation approach is to view the dama gazelle as a single species without subspecific divisions. © 2014 Senn et al.

Objective: To determine the prevalence of Cysticercus tenuicollis (C. tenuicollis) metacestodes in five oryx species kept in Al Ain Zoo animal collection. Methods: This study was based on a retrospective analysis of post-mortem records covering a four year period (July 2010 to July 2014). Results: A total of 213 individual animals were recorded dead during the four year period (July 2010 to July 2014). Out of this, 12 (5.6%) were recorded with C. tenuicollis. More females (8) than males (4) were recorded to have C. tenuicollis, although this was not statistically significant (P = 0.373. 7). Conclusions: This study shows that, Arabian oryx, beisa oryx, fringe-eared oryx, gemsbok and scimitar-horned oryx are susceptible to C. tenuicollis. Based on the epidemiology and the life cycle of this parasite, it is possible that these captive animals ingested the parasite through contaminated feed which could have happened in the pasture land or stray dogs and wild canidae (e.g. fox) visited the zoo contaminating the oryx feed. Stray dogs and wild canidae should be prevented from visiting pasture land and a captive animal facility. © 2015 Hainan Medical University.
