Conservation: Reproductive collapse in saiga antelope harems.
E. J. Milner-Gulland,O. M. Bukreeva,Tim Coulson,A. A. Lushchekina,M. V. Kholodova,A. B. Bekenov,Iu. A. Grachev +6 more
TL;DR: It is shown that reproductive collapse in the critically endangered saiga antelope is likely to have been caused by a catastrophic drop in the number of adult males in this harem-breeding ungulate, probably due to selective poaching for their horns.

Tracking greenery across a latitudinal gradient in central Asia - the migration of the saiga antelope
TL;DR: In this article, the authors identified ecological drivers of saiga migration, compared four populations in terms of differences in the geographical characteristics of their ranges and the factors affecting habitat selection within the seasonal ranges.

M. V. Kholodova,E. J. Milner-Gulland,A.J. Easton,L. Amgalan,Iu.A. Arylov,A. B. Bekenov,Iu. A. Grachev,A. A. Lushchekina,Oliver A. Ryder +8 more
TL;DR: Analysis of the mtDNA control region (HV1) of 93 tissue samples from all five populations of the saiga antelope Saiga tatarica shows a slight but clear distinction between S. t.
Monitoring population productivity in the saiga antelope
Aline Kühl,Atle Mysterud,Iu. A. Grachev,A. B. Bekenov,B. S. Ubushaev,A. A. Lushchekina,E. J. Milner-Gulland +6 more
TL;DR: The recent poaching-driven collapse in saiga numbers has potentially resulted in reductions in fecundity, which will have an impact on population growth rate, and the potential for monitoring of twinning rate using non-invasive calving aggregation transects is highlighted.
