Prehistoric Human Impacts to Marine Mollusks and Intertidal Ecosystems in the Pacific Islands

From long-term stratigraphic records in Pacific Island archaeological sites, researchers have documented alterations to molluskan species richness and abundance, decreases or increases in mollusk shell size and, in rare cases, human foraging may have contributed to the extirpation of mollusk taxa. Mollusks perform critical ecosystem functions in tropical intertidal environments, including improving water quality through filtration, regulating algal cover, and increasing habitat and substratum complexity through ecosystem engineering. These critical ecosystem functions can be negatively affected by human foraging, possibly contributing to decreased resilience of coral reefs to climatic alterations. We review modern ecological research on human impacts to mollusks and intertidal ecosystems that illustrates the mechanisms and effects of human foraging. We then examine centuries to millennial scale archaeological records from the Pacific Islands to understand long-term, time-averaged trends in human impacts to intertidal ecosystems.     

Stumbling towards Empire: The Shanghai Local Post Office,the Transnational British Community and Informal Empire in China, 1863–97

In the second half of nineteenth century, a small transnational British and foreign community grew up in the treaty ports scattered along China’s coast, a community literally caught between the great inner Asian empire of the Manchu Qing and British-dominated informal empire in Asia. Although scholars often contend that few major developments occurred in the foreign sector of the treaty port world until the very end of the nineteenth century, this article joins recent revisionist scholarship seeking to better understand the growth of this transnational treaty port community through a study of the Shanghai Municipal Council’s local post office in the context of informal empire prior to the rise of muscular Chinese nationalism in the early twentieth century.

As an institutional history of the virtually unknown local post office, this article is a study of the decades-long process by which the foreign settler community of Shanghai slowly built up the administrative capacity, trading networks and communications infrastructure of informal empire and semi-colonial order in the nineteenth-century treaty ports. The history of the local post office is largely unknown not because of its insignificance, but because we have not paid enough attention to the institutions that facilitated the emergence of transnational expatriate and settler communities throughout the world of British informal empire and the global and local influences that shaped them.     

Analysis of the Size,Shape, and Modeled Age of Common Limpets (Patella vulgata) from Late Norse Middens at Sandwick,Unst, Shetland Islands,UK: Evidence for Anthropogenic and Climatic Impacts

Zooarchaeological faunal remains are commonly examined to investigate harvesting behavior. We determined limpet (Patella vulgata) shell size and shape, and estimated shell age from several middens at the Late Norse Sandwick South Site, Unst, Shetland, UK, whose strata represent distinct occupational phases (Phase 1: AD 1100–1200, Phase 2: AD 1200–1250, Phase 3: AD 1250–1350). Our goal was to determine if the many limpets found there could provide insight into Norse harvesting behavior. Shell length, conicity, and modeled age all declined between Phases 1 and 2, suggesting intensive, size-selective harvesting of limpets and a shift to harvesting lower in the intertidal zone between phases. Length and conicity varied in Phases 2 and 3 and no major changes seem to have occurred over these periods, indicating that harvesting maintained the limpet population at an impacted level throughout the later phases. The conicity decline between Phases 1 and 2 may also have been caused by increased storminess that accompanied the onset of the Little Ice Age. The mean length of modern limpet populations near the Norse site did not differ from the archaeological phases, but did vary among collection years. Limpets were 26% larger in 2015 than in 2012 and 2013, indicating that large interannual variations in population structure can occur over short time periods. Potentially the result of extreme storms removing small limpets, this result raises the possibility that size and conicity changes during the Sandwick South Site occupation, as well as in other early populations, could also be the result of environmental factors rather than human harvesting alone. We feel, however, that the most parsimonious explanation for the patterns we document is human harvesting.     

Human Right to Water: Contemporary Challenges and Contours of a Global Debate

Abstract: In recent years, significant debate has taken place around the concept of the “human right to water”. In this paper, we seek to respond to recent critiques and clarify the terms of the debate by presenting an in‐depth exploration of the human right to water. We explore several critiques of the concept, situate it in the context of the current neoliberalization of water provision and in relation to contemporary water challenges, and present some examples of how it has been deployed to further the cause of access to water for vulnerable populations in varied contexts. We conclude that, rather than abandoning the concept as critics have suggested, the human right to water maintains importance as a discourse and strategy in the contemporary moment.
