The ecology and management of the Saiga antelope in Kazakhstan

Mammal Review, 1998
AbstractThe ecology and management of the Saiga antelope Saiga tatarica tatarica, a nomadic herding species of the desert, semi‐desert and steppe ecosystems of Central Asia, are reviewed. The range area and population size of the Saiga in Kazakhstan have changed substantially since they were first described, declining rapidly through the nineteenth ...

A STOCHASTIC DYNAMIC PROGRAMMING MODEL FOR THE MANAGEMENT OF THE SAIGA ANTELOPE

Ecological Applications, 1997
A stochastic dynamic programming model for the optimal management of the saiga antelope is presented. The optimal hunting mortality rate and proportion of adult males in the harvest are found as functions of the size and structure of the saiga population before hunting.

Osteomorphological features of the hind limb bones of Saiga antelope (Saiga tatarica)

Anatomia, Histologia, Embryologia, 2020
AbstractThe intralimb indices and calcaneal linear metrics are known as the reliable predictors of locomotor adaptation in artiodactyls. The osteological features of hindlimb in adult Saiga (Saiga tatarica) were described, and its correlation with cursoriality and habitat adaptation was discussed.

TOXOPLASMOSIS IN NILGAIS (BOSELAPHUS TRAGOCAMELUS) AND A SAIGA ANTELOPE (SAIGA TATARICA)

Journal of Zoo and Wildlife Medicine, 2004
Three captive female nilgais (Boselaphus tragocamelus) either showed late-term abortion or their newborn calves died within 2 days of birth. Toxoplasma gondii DNA was demonstrated in the brain and liver of each fetus and in one of the two neonates by single-stage polymerase chain reaction (PCR) with TGR1E and by seminested PCR with B1 gene ...

PARATUBERCULOSIS IN SAIGA ANTELOPE (SAIGA TATARICA) AND EXPERIMENTAL TRANSMISSION TO DOMESTIC SHEEP

Journal of Wildlife Diseases, 1992
Mycobacterium paratuberculosis was isolated in low numbers from the small intestine and associated mesenteric lymph nodes of a saiga antelope (Saiga tatarica) using routine culture techniques in spite of histologic evidence of high numbers of acid-fast bacteria in these tissues.

TOXOPLASMOSIS IN CAPTIVE SAIGA ANTELOPE

Journal of Wildlife Diseases, 1971
Disseminated toxoplasmosis was diagnosed in saiga antelope (Saiga tatarica) from a Canadian zoo. Multiple foci of necrosis were found in most tissues of the animals. Toxoplasma cysts were found in association with these lesions. Toxoplasma trophozoites were recovered from mice injected with infected tissues.

Monitoring population productivity in the saiga antelope

Animal Conservation, 2009
AbstractEffective conservation requires a good understanding of factors causing variation in population growth rate. We here analyse the relationship between female age and fecundity in the saiga antelope Saiga tatarica tatarica, a critically endangered ungulate of the Eurasian steppes and semideserts, at both individual and population levels.

Status and exploitation of the saiga antelope in Kalmykia

1996
From a population of over 750 000 in 1958, the number of saiga antelope in the northwestern Caspian region of the Autonomous Republic of Kalmykia, Russian Federation, is now about 160 000. The range of the species has been reduced from over 120 000 km2 to about 20 000 km2. Intensive grazing, principally by sheep and also by cattle, and attempts to farm

A Population Model for the Management of the Saiga Antelope

The Journal of Applied Ecology, 1994
In order to describe the population dynamics of the saiga antelope adequately, a discrete time, stochastic age-structured model is needed. Management strategies investigated are: taking a proportion of the population or a constant number of individuals; selecting the individuals killed by age and sex or harvesting in the proportions found in the ...
