A database of ca. 970 radiocarbon dates on bones, teeth, and tusks of the woolly mammoth (Mammuthus primigenius Blum.) from Siberia was created in order to understand the spatiotemporal distribution of this species over the last 50,000 14C years (BP). Mammoths populated all parts of Siberia until ca. 12,000 BP. After that, a few refugia exited south of ca. 60°N at ca. 10,600–12,000 BP, and in the northern part of mainland Siberia mammoths survived until ca. 9700 BP. At ca. 9500–3700 BP, they existed only in today’s insular regions such as the New Siberian Islands and Wrangel Island in the High Arctic. The relationship between the dynamics of mammoth populations and climatic fluctuations is complicated. In the warmer intervals (interstadials), the number of mammoths in Siberia was generally slightly larger than in the colder times (stadials); however, the difference is often not significant. The connection between the dynamics of mammoth populations and climatic fluctuations in Siberia is therefore complicated and non-linear.
Although coarticulatory variation is largely systematic, and serves as useful information for listeners, such variation is nonetheless linked to sound change. This article explores the articulatory and perceptual interactions between a coarticulatory source and its effects, and how these interactions likely contribute to change. The focus is on the historical change VN (phonetically, ṼN) > Ṽ, but with more general attention to how a gesture associated with a source segment comes to be reinterpreted as distinctively, rather than coarticulatorily, associated with a nearby vowel or consonant. Two synchronic factors are hypothesized to contribute to reinterpretation: (i) articulatory covariation between the duration of the coarticulatory source (here, N) and the temporal extent of its effects (Ṽ), and (ii) perceived equivalence between source and effect. Experimental support for both hypotheses is provided. Additionally, the experimental data are linked to the historical situation by showing that the contextual conditions that trigger (i) and (ii) parallel the conditions that historically influence phonologization of vowel nasalization.
