    In:  Supplement to: Waterson, Amy; Edgar, Kirsty M; Schmidt, Daniela N; Valdes, Paul J (2017): Quantifying the stability of planktic foraminiferal physical niches between the Holocene and Last Glacial Maximum. Paleoceanography, https://doi.org/10.1002/2016PA002964
    Publication Date: 2023-07-07
    Description: The application of transfer functions on fossil assemblages to reconstruct past environments is fundamentally based on the assumption of stable environmental niches in both space and time. We quantitatively test this assumption for six dominant planktic foraminiferal species (Globigerinoides ruber (pink), G. ruber (white), Trilobatus sacculifer, Truncorotalia truncatulinoides, Globigerina bulloides and Neogloboquadrina pachyderma) by contrasting reconstructions of species realised and optimum distributions in the modern and during the Last Glacial Maximum (LGM) using an ecological niche model (ENM; MaxEnt) and ordination framework. Global ecological niche models calibrated in the modern ocean have high predictive performance when projected to the LGM for sub-polar and polar species, indicating that the environmental niches of these taxa are largely stable at the global scale across this interval. In contrast, ENM's had much poorer predictive performance for the optimal niche of tropical-dwelling species, T. sacculifer and G. ruber (pink). This finding is supported by independent metrics of niche margin change, suggesting that niche stability in environmental space was greatest for (sub)polar species, with greatest expansion of the niche observed for tropical species. We find that globally calibrated ENMs showed good predictions of species occurrences globally, whereas models calibrated in either the Pacific or Atlantic Oceans only and then projected globally performed less well for T. sacculifer. Our results support the assumption of environmental niche stability over the last ~21,000 years for most of our focal planktic foraminiferal species and thus, the application of transfer function techniques for palaeoenvironmental reconstruction during this interval. However, the lower observed niche stability for (sub)tropical taxa T. sacculifer and G. ruber (pink) suggests that (sub)tropical temperatures could be underestimated in the glacial ocean with the strongest effect in the equatorial Atlantic where both species are found today.

    Notes: Abstract This paper investigates the determinants of price dispersion between different goods in grocery retailing, as the result of pricing decisions of multiproduct retailers. Demand parameters are generated using the LES system. These are then used to test theoretical predictions about the nature of supermarkets' pricing and consumers' shopping behaviour using disaggregated data from the Italian grocery trade. The empirical results concerning the supply function provide evidence for the existence, in all types of retail organisation, of a monopolistic form of price discrimination. The results are consistent with discrimination due to the exploitation of customers' switching costs.

    Description: Fieldwork extending over a thirty-year period provided materials for this book. Paths and Rivers offers an unusually deep and broad picture of the Sa’dan Toraja as a society in dynamic transition over the course of the past century. The Toraja inhabit the mountainous highlands of South Sulawesi, Indonesia, and are well known for their dramatic architecture, their unusual cliff burials, and their flamboyant ceremonial life, which places extraordinary economic demands on individuals and families. The analysis is informed, firstly, by a comparative perspective which sets Toraja social structure in the context of the Austronesian world. Secondly, the author delves deeply into Toraja social memory to show how people think about the past. She examines the usefulness of history and myth in the present as a source of identity, a template for action, or a resource by means of which to claim precedence. The book gives a clear picture of the structure and ethos of the indigenous Toraja religion, the Aluk To Dolo or ‘Way of the Ancestors’, with its complex cycle of rituals. The book concludes with an analysis of the ceremonial economy, which draws upon both domestic subsistence production and the global market economy. Paths and Rivers draws together a fascinating picture of one society’s journey into modernity. Roxana Waterson is Associate Professor in the Department of Sociology, National University of Singapore. She is also the author of The living house: an anthropology of architecture in Southeast Asia (3rd ed., Thames and Hudson, 1997) and Southeast Asian lives: Personal narratives and historical experience (Singapore University Press/Ohio University Press, 2007).
