Description
The Great Bustard (Otis tarda) is an iconic species of the temperate grasslands of Europe and Asia, a habitat that is among the least protected ecosystems in the world. A distinct subspecies, the Asian Great Bustard (O. t. dybowskii), is poorly understood due to its wary nature and remote range in Siberia, Mongolia, and northern China. This subspecies is now endangered by rapid development.
Using satellite telemetry and remote sensing, I investigated three aspects of the Asian Great Bustard’s ecology critical to its conservation: migratory routes, migratory cues, and habitat use patterns. I found that Asian Great Bustards spent one-third of the year on a 2000 km migratory pathway, a distance twice as far as has previously been recorded for the species. Tracked individuals moved nomadically over large winter territories and did not repeat migratory stopovers, complicating conservation planning. Migratory timing was variable and migratory movements were significantly correlated with weather cues. Specifically, bustards migrated on days when wind support was favorable and temperature presaged warmer temperatures on the breeding grounds (spring) or advancing winter weather (fall). On the breeding grounds, Asian Great Bustards used both steppe and wheat agriculture habitat. All recorded reproductive attempts failed, regardless of habitat in which the nest was placed. Agricultural practices are likely to intensify in the coming decade, which would present further challenges to reproduction. The distinct migratory behavior and habitat use patterns of the Asian Great Bustard are likely adaptations to the climate and ecology of Inner Asia and underscore the importance of conserving these unique populations.
My research indicates that conservation of the Asian Great Bustard will require a landscape-level approach. This approach should incorporate measures at the breeding grounds to raise reproductive success, alongside actions on the migratory pathway to ensure appropriate habitat and reduce adult mortality. To secure international cooperation, I proposed that an increased level of protection should be directed toward the Great Bustard under the Convention on Migratory Species (CMS). That proposal, accepted by the Eleventh Conference of Parties to CMS, provides recommendations for conservation action and illustrates the transdisciplinary approach I have taken in this research.

Description
This dissertation discusses children and childhood in Soviet Kazakhstan from 1928 to 1953. By exploring images of, and for, children, and by focusing on children’s fates during and after the famine of 1930-33, I argue that the regime’s success in making children socialist subjects and creating the new Soviet person was questionable throughout the 1930s. The reach of Soviet ideological and cultural policies was limited in a decade defined by all kinds of shortcomings in the periphery which was accompanied by massive violence and destruction. World War 2 mobilized Central Asians and integrated the masses into the Soviet social and political body. The war transformed state-society relations and the meaning of being Soviet fundamentally changed. In this way, larger segments of society embraced the framework for Soviet citizenship and Soviet patriotism largely thanks to the war experience. This approach invites us to reconsider the nature of Sovietization in Central Asia by questioning the central role of ideology and cultural revolution in the formation of Soviet identities. My dissertation brings together images of childhood, everyday experiences of children and memory of childhood. On the one hand, the focus on children provides me an opportunity to discuss Sovietization in Central Asia. On the other hand, this dissertation contributes to our understanding of Soviet childhood: it is the first comprehensive study of Soviet children in the periphery in English. It shows how images and discourses, which were produced in the Soviet center, were translated into the local context and emphasizes the multiplicity of children’s experiences across the Soviet Union. Local conditions defined the meaning of childhood in Kazakhstan as much as central visions. Studying children in a non-Russian republic allows me to discuss questions of ideology, cultural revolution and the nationalities question. A main goal of the dissertation is to shift the focus of Sovietization from the cultural and intellectual elite to ordinary people. Secondly, by studying the impact of the famine and the Great Patriotic War, I try to understand the dynamics of the Soviet regime and the changing conceptions of culture and identity in Soviet Kazakhstan.
