A 17 month old female gazelle dorca (Gazella dorcas neglecta), kept in captivity in a Spanish zoo, showed several symptoms of illness including fever, lethargy and behavioural changes. (X)-ray revealed ruminal "foreign bodies" and pneumonia with a nodular pattern. After surgical intervention, the animal died. At necropsy, histopathologic and microbiological findings were consistent with the diagnosis of disseminated histoplasmosis, with an inflammatory histological pattern associated with immunodepression in the animal, similar to those observed in patients with severe immunodeficiency (AIDS and others).

Agonistic interactions and social behaviors in the Saharan Dorcas gazelle (Gazella dorcas neglecta): Using social network analysis to evaluate relationships and social structure in captive male groups.

Social interactions, including agonistic behavior, are very important for the management and welfare of individuals forming groups in captivity. One of the main concerns for the stability and durability of adult male groups is a noticeable level of intraspecific aggression. This study comprises a Social Network Analysis to illustrate social structure in different groups of captive Saharan Dorcas gazelles (Gazella dorcas neglecta).

The objectives were to describe the morphometric measurements and determine the best model for estimating the relationship between body weight and morphometric measurements of the two Sudanese antelopes, Dorcas Gazelle (Gazella dorcas) and Bohor Reedbuck (Redunca redunca). Twenty-four animals belonging to two Sudanese antelope species, six males and six females from each species were used. Data on body weight and body measurements were recorded from each species.

Inbreeding threatens the survival of small populations by producing inbreeding depression, but also exposes recessive deleterious effects in homozygosis allowing for genetic purging. Using inbreeding-purging theory, we analyze early survival in four pedigreed captive breeding programs of endangered ungulates where population growth was prioritized so that most adult females were allowed to contribute offspring according to their fitness. We find evidence that purging can substantially reduce inbreeding depression in Gazella cuvieri (with effective population size N = 14) and Nanger dama (N = 11).

Knowledge of factors affecting semen quality could be of great importance for the collection and preservation of semen from threatened animals. To assess the effect of seasonality, sperm parameters and testosterone levels were examined throughout the year and compared with the distribution of conceptions. Cuvier's gazelle showed higher sperm quantity in April, coinciding with one peak of conceptions.
