Correction: Investigation of biochemical and physiological parameters of the newborn Saiga antelope (Saiga tatarica) in Gansu Province, China

Toxoplasmosis in nilgais (Boselaphus tragocamelus) and a saiga antelope (Saiga tatarica).

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. Retrospectively, antibodies titers > or =640 to T. gon...

Factors Affecting Survival and Cause-specific Mortality of Saiga Calves (Saiga tatarica mongolica) in Mongolia

Factors affecting juvenile survival are poorly known in the world’s most northern antelope, the endangered saiga (Saiga tatarica), yet they are fundamental for understanding what drives population change. For saiga neonates monitored in Sharga Nature Reserve, western Mongolia, during 2008–2010, male and single calves were heavier than those of female and twins, respectively. However, there was ...

Population estimates of Endangered Mongolian saiga Saiga tatarica mongolica: implications for effective monitoring and population recovery

The global population of saiga Saiga tatarica, categorized as Critically Endangered on the IUCN Red List, declined by. 95% at the end of the 20th century, resulting in several conservation initiatives to protect the species. Previously used methods to monitor population trends were inadequate to assess numbers of saiga properly. We report findings from the first survey for Mongolian saiga S. ta...

Calving location selection patterns of saiga antelope in Mongolia

The 'big spenders' of the steppe: sex-specific maternal allocation and twinning in the saiga antelope.

In polygynous mammals, males generally benefit more from extra allocation of maternal resources than females. However, limitations to sex-specific allocation are usually ignored. We propose the 'allocation constraint' hypothesis, whereby maternal resource allocation is more likely to follow life-history predictions in single sex litters than in mixed sex litters, due to limitations in prenatal ...
