In addition to the well-worn observation that rituals do not simply enact but produce social realities, and moving beyond the exhausted note that rituals produce visions of history, Quijada attends to the complex narrative content of the historical knowledge made by Buryats in original and remarkably effective ways. In different ritual genres, or in different narrative frames connected to a single ritual, Quijada's Buryat informants link models of time to place. Justine Buck Quijada's I Buddhists, Shamans, and Soviets: Rituals of History in Post-Soviet Buryatia i explores this fascinating question. [Extracted from the article]

The article discusses that an introduction of desire has much to contribute to the study of religion, capital, and capitalism. Topics include this is particularly evident as one moves from more widely studied liberal, post-Protestant, and secular social ecologies to capital's new homelands in Asia, and the concentration of global capital in the previously colonial, slave-based, and industrialized economies of Western Europe and America has been moving for decades towards urban centers in Asia.

This article proposes that many Tibetan rituals are shaped by a language of creating, giving, and eating food. Drawing on a range of premodern texts and observation of a week-long Accomplishing Medicine (sman sgrub) ritual based on those texts, we explore ritualized food interactions from a narrative perspective. Through the creation, offering, and consumption of food, ritual participants, including Buddhas, deities, and other unseen beings, create and maintain variant identities and relationships with each other. Using a ritual tradition that crosses religious and medical domains in Tibet, we examine how food and eating honors, constructs, and maintains an appropriate and spatiotemporally situated community order with a gastronomic contract familiar to all participants.

While speciation can be found in the presence of gene flow, it is not clear what impact this gene flow has on genome- and range-wide patterns of differentiation. Here we examine gene flow across the entire range of the common sunflower, H. annuus, its historically allopatric sister species H. argophyllus and a more distantly related, sympatric relative H. petiolaris. Analysis of genotypes at 26 microsatellite loci in 1015 individuals from across the range of the three species showed substantial introgression between geographically proximal populations of H. annuus and H. petiolaris, limited introgression between H. annuus and H. argophyllus, and essentially no gene flow between the allopatric pair, H. argophyllus and H. petiolaris. Analysis of sequence divergence levels among the three species in 1420 orthologs identified from EST databases identified a subset of loci showing extremely low divergence between H. annuus and H. petiolaris and extremely high divergence between the sister species H. annuus and H. argophyllus, consistent with introgression between H. annuus and H. petiolaris at these loci. Thus, at many loci, the allopatric sister species are more genetically divergent than the more distantly related sympatric species, which have exchanged genes across much of the genome while remaining morphologically and ecologically distinct.

Island systems have long been useful models for understanding lineage diversification in a geographic context, especially pertaining to the importance of dispersal in the origin of new clades. Here we use a well-resolved phylogeny of the flowering plant genus Cyrtandra (Gesneriaceae) from the Pacific Islands to compare four methods of inferring ancestral geographic ranges in islands: two developed for character-state reconstruction that allow only single-island ranges and do not explicitly associate speciation with range evolution (Fitch parsimony [FP; parsimony-based] and stochastic mapping [SM; likelihood-based]) and two methods developed specifically for ancestral range reconstruction, in which widespread ranges (spanning islands) are integral to inferences about speciation scenarios (dispersal-vicariance analysis [DIVA; parsimony-based] and dispersal-extinction-cladogenesis [DEC; likelihood-based]). The methods yield conflicting results, which we interpret in light of their respective assumptions. FP exhibits the least power to unequivocally reconstruct ranges, likely due to a combination of having flat (uninformative) transition costs and not using branch length information. SM reconstructions generally agree with a prior hypothesis about dispersal-driven speciation across the Pacific, despite the conceptual mismatch between its character-based model and this mode of range evolution. In contrast with narrow extant ranges for species of Cyrtandra, DIVA reconstructs broad ancestral ranges at many nodes. DIVA results also conflict with geological information on island ages; we attribute these conflicts to the parsimony criterion not considering branch lengths or time, as well as vicariance being the sole means of divergence for widespread ancestors. DEC analyses incorporated geological information on island ages and allowed prior hypotheses about range size and dispersal rates to be evaluated in a likelihood framework and gave more nuanced inferences about range evolution and the geography of speciation than other methods tested. However, ancestral ranges at several nodes could not be conclusively resolved, due possibly to uncertainty in the phylogeny or the relative complexity of the underlying model. Of the methods tested, SM and DEC both converge on plausible hypotheses for area range histories in Cyrtandra, due in part to the consideration of branch lengths and/or timing of events. We suggest that DEC model-based methods for ancestral range inference could be improved by adopting a Bayesian SM approach, in which stochastic sampling of complete geographic histories could be integrated over alternative phylogenetic topologies. Likelihood-based estimates of ancestral ranges for Cyrtandra suggest a major dispersal route into the Pacific through the islands of Fiji and Samoa, motivating future biogeographic investigation of this poorly known region.
