Patterns of Resource Use and Isotopic Niche Overlap Among Guanaco (Lama guanicoe), Pampas Deer (Ozotoceros bezoarticus) and Marsh Deer (Blastocerus dichotomus) in the Pampas. Ecological,Paleoenvironmental and Archaeological Implications

ABSTRACT

In this paper, we analyze the isotopic niche and resource use of the guanaco (Lama guanicoe), pampas deer (Ozotoceros bezoarticus) and marsh deer (Blastocerus dichotomus) on the temperate plain of the northern Pampa region in the southeast of South America. The measured stable isotope compositions in bone tissue are δ¹³C, δ¹⁵N and δ¹⁸O. All the analyzed samples were recovered from different archaeological sites from the late Holocene. According to the results, the guanaco was strictly confined to the Pampa plain environment, developing a broad niche based on C₃ plants and a variable contribution of C₄ grasses within a grazing trend. The pampas deer preferentially used the Pampa plain, but also the prairies on the borders of the wetland, showing eurioic characteristics and a narrower niche based on C₃ plants. In turn, the marsh deer was strictly confined to wetland environments, developing a C₃ diet–base, within a narrow isotopic niche and stenoic characteristics. The three mammals showed a wide range of intraspecific variability, which was a key factor in their adaptability to spatial and temporal changes in the vegetation coverage. In fact, the temporal trends of their isotopic values were concurrent with the major climatic variations of the Holocene. Differences in the correlations between the values of both carbon sources in both deer species compared with the guanaco suggest a distinct chemical composition of their diet and/or differences in the allocation of nutrients. The isotopic values of nitrogen and spacing of the carbon sources in guanaco (pseudoruminant) and both deer species (ruminants) show no significant differences between them, thus establishing the values for local large herbivores. Significant correlations between δ¹³C and δ¹⁵N were found in the guanaco and marsh deer. The regional and extra–regional variability in the guanaco's δ¹³C_collagen and δ¹⁵N probably reflect the clinal variations in the vegetation coverage and the amount of rainfall. The collagen isotope values in the guanaco throughout the entire Holocene show that the humid Pampa would have shifted between being a more recurrent mesic and temperate plain with minor phases of dry–mesic conditions like during the Little Ice Age, and a humid and warm one at the peaks of the Holocene Thermal Maximum and the Medieval Climatic Anomaly. The guanaco and the pampas deer adapted to all the climatic changes that happened on the humid Pampa until the biological invasions of large European mammals changed the herbivores’ guild composition of this vast plain, pushing them into peripheral habitats due to competition. The within–species variability in isotopic signals through time and space make it necessary to carry out adequate sampling before reconstructing the diets of local past populations.

The United Nations at Niagara: Borderlands Collaboration and Emerging Globalism

In 1946 a group of Western New York and Southern Ontario business leaders proposed locating United Nations headquarters on Navy Island, Canadian territory in the Niagara River. One of the most visionary proposals ever to come from the region, it was a genuinely binational project, grounded in the symbolism of the peaceful relationship along the Niagara after the War of 1812. The proposal revealed a high level of cross-border economic and cultural integration in the Niagara region that had been strengthened by the shared experience of World War II. However, the region was increasingly marginalized from its national and state/provincial cores as it struggled to integrate itself into an ever more globalized economy.     

REGION‐BUILDING IN THE ARCTIC PERIPHERY: THE DISCURSIVE CONSTRUCTION OF A PETROLEUM REGION

As social communities, regions are built through discourses that convey images of what the region is. Regions are built for a variety of reasons, including political and economic ones. This implies that changing economic circumstances have the potential to change the discourses on regional identities. Petroleum discoveries represent such a potential change in the economic circumstances of a region. This study of an emerging petroleum region in the north of Norway shows that a regional identity discourse is used to claim ownership over the petroleum resources in the Barents Sea in order to justify the need for a production plan that maximizes regional economic benefits. In this way, the discovery of petroleum represents an opportunity to reinforce regional identities around a set of common interests. However, “the region” is vaguely defined in this discourse, being used in reference to two different scales: Finnmark and Northern Norway.     

Chenopodium Seeds in Open-Air Archaeological Sites – How to Not Throw the Baby Out with the Bathwater

ABSTRACT

Differentiating between charred and uncharred plant remains may appear straightforward but for some taxa (here fat-hen, Chenopodium album type) can be very problematic. Recognition of the preservation state is obviously crucial for archaeobotanical data derived from dry, open-air sites. Fat-hen as a common weed, is also one of the most important components of a persistent soil seed bank. It is also a well-known food plant, gathered or cultivated. Numerous findings of fat-hen seeds in unclear states of preservation were noted in the Early Neolithic sites of the Linear Pottery culture in Kuyavia (N Europe). In previous studies such specimens were omitted as probably uncharred. Re-examination of Neolithic finds of fat-hen from that region showed the link of their abundancy with the earliest phases of the Neolithic occupation. The plant probably played an important role in the diet of the early Neolithic settlers there. It may indicate intensive use of local, open, fertile, probably alluvial areas. Distinguishing between ancient and modern specimens of that common weedy plant, producing large amounts of small, black, resistant seeds is thus very important, holding a great potential to shed new light on the origins of agricultural societies in this part of northern Europe.     

“长于姜水”、“都陈”与“葬于长沙”——炎帝传说流衍途径考察

在炎帝传说流衍的过程中,逐渐形成其"长于姜水"、"都陈"与"葬于长沙"的说法。诸说之间似乎缺乏必然的联系,但均有历史与文化的渊源。早在先秦时期,炎帝传说在东、西方流传之时,亦有缘起于南方说流行。随着东汉后期"三皇五帝"系统整合工作的完成,以及魏晋时期以现实生活中的帝王为标准,对传说中古帝王的生平事迹、都城、陵墓所在等关键环节的再次整合,尽管依旧保留着相当浓郁的传说色彩,然而炎帝的人格化倾向却日益凸现,这是古代帝王传说演变过程中一个值得关注的历史文化现象。"姜水"、"陈"与"长沙",似乎可以被理解为炎帝传说流衍过程中三个重要的地理标志,各地不同的炎帝传说借此得以整合,最终形成一个与黄帝并称的华夏民族始祖形象。     

Geographic earnings inequality by race, 1960–2016

Geographic inequality and racial disharmony are considered major factors in America's political divergence. This paper calculates geographic earnings inequality from 1960 to 2016 separately by race. From 2000 to 2016, White geographic inequality was significantly higher, and Hispanic geographic inequality was significantly lower, than Black and Asian geographic inequality. White geographic inequality rose from 1980 to 2008. Black and Hispanic geographic inequality fell from 1960 to 1980. Rural controls explain substantial shares of White geographic inequality in all years. Region and rural controls account for large shares of Black geographic inequality, especially from 1960 to 1990. Post-1990, geographic inequality changes are largely explained by changes in overall earnings inequality, but 1960–1990 changes are not. Between-race differences in geographic inequality translate into high-income metropolitan statistical areas having had, since 1980, significantly smaller shares of Whites among their low-income residents.     

Regional Devolution and Regional Economic Success: Myths and Illusions about Power

The proposition that regional devolution in and of itself will lead to economic success has become deeply embedded in beliefs and policy discourses about the determinants of regional prosperity, and in turn has led to political demands for such devolution. In this paper I seek critically to examine such claims, using the case of the north‐east of England as the setting for this examination. The paper begins with some introductory comments on concepts of power, regions, the reorganization of the state and of multi‐level governance, and governmentality, which help in understanding the issues surrounding regional devolution. I then examine the ways in which north‐east England was politically and socially constructed as a particular type of region, with specific problems, in the 1930s — a move that has had lasting significance up until the present day. Moving on some six decades, I then examine contemporary claims about the relationship between regional devolution and regional economic success, which find fertile ground in the north‐east precisely due to its long history of representation as a region with a unified regional interest. I then reflect on the processes of regional planning, regional strategies and regional devolution, and their relationship to regional economic regeneration. A brief conclusion follows, emphasizing that questions remain about the efficacy of the new governmentality and about who would be its main beneficiaries in the region. The extent to which devolution would actually involve transferring power to the region and the capacity of networked forms of power within the region to counter the structural power of capital and shape central state policies remains unclear.     

中国行政区划改革的内卷化风险及其生成机制

透过对行政区划调整现象与文献的梳理，发现中国部分政区有“改而不变”的倾向，本文借用“内卷化”的概念对这种现象及其效应进行探讨，指出政区改革在行政层级、运行逻辑、空间关系、职能配置等方面都存在着“内卷化”隐忧。在此基础上，通过对国家结构、行政区划的资源属性和行政区经济之间关联的分析，阐释了政区改革内卷化的生成机制，认为行政区划配置资源的功能可能是政区改革陷入内卷化的一个重要前提。最后以常州武进和海南政区改革为例，探讨了本研究的分析框架与逻辑，并建议构建面向市场经济的行政区划调整框架，为继续深化行政体制改革提供空间支撑。     

Origine,développement et ancrage territorial des microbrasseries artisanales : le cas de l'Est-du-Québec

This article focuses on the development of a new industry, namely the brewing industry, in the peripheral region of Southeastern Quebec. Its objective is to understand and describe the main activities of the microbreweries and to detect their contribution to the development of Southeastern Quebec, namely the Lower-Saint-Lawrence and the Gaspé peninsula-Magdelen islands regions. The results of our analysis allow us to shed new light on the contribution of this industry to the development of these two regions.
