The first comprehensive description of the biodiversity and biogeography of Antarctic and Sub-Antarctic intertidal communities

Aim To describe the distribution of biodiversity and biogeographical patterns of intertidal organisms in southern temperate and polar waters. We hypothesized that there would be differences in community structure between the Antarctic, which is most affected by ice, and the sub-Antarctic and other neighbouring regions. We also hypothesized that rafting and West Wind Drift will be the significant drivers of biogeographical patterns. Additionally, the size, age, isolation, volcanic or glacial history of a region and the presence of large, beach dwelling, mammals and birds would all play a role in determining the level of biodiversity observed. Location South Atlantic, Indian and Pacific Oceans and the Southern Ocean. Methods We examined all available intertidal records from the Antarctic and sub-Antarctic with additional data from neighbouring regions for comparison and context. We compiled 3902 occurrences of 1416 species of high southern latitude intertidal organisms from 229 locations and used PRIMER 6 to perform multivariate statistical analyses. Results The Antarctic and sub-Antarctic are shown to be distinct biogeographical regions, with patterns driven by a small number of widely distributed species. These wide-ranging molluscs and macroalgae dominate the biogeographical structure of the Southern Ocean intertidal, most likely as a result of rafting in the Antarctic Circumpolar Current. East Antarctic intertidal habitats are potentially isolated by the Ross and Weddell Sea ice shelves but represent a great unknown in this biogeographical scheme. Main Conclusions The view that the Antarctic intertidal is a lifeless desert does not hold true, with Antarctic Peninsula intertidal communities being richer and more diverse than those in southern South America and the sub-Antarctic islands. Changing conditions in the Antarctic and sub-Antarctic intertidal mean that a representative baseline is needed (acquired through standardized and quantitative sampling) to assess future changes and to detect any invasive species

New insights into the fertility patterns of recent Polish migrants in the United Kingdom

There have been important changes in the United Kingdom’s (UK) fertility and immigration in the past decade, with a large share contributed by migrants from Poland. A detailed understanding of Polish migrant fertility is lacking, however, because the relevant data are not routinely collected. This paper provides new insights into the fertility patterns of Polish migrants in the UK, and compares these patterns with those of other large immigrant groups, the UK-born population and with patterns in Poland. We use the UK Labour Force Survey with the Own Child(ren) Method, illustrating the potential of survey data for estimating immigrant fertility in settings where other data are unavailable. We first compare the fertility patterns of recent Polish migrants with those of other key recent immigrant groups and the UK-born population; estimating: 1) Age-Specific Fertility Rates (ASFRs), and Total Fertility Rates (TFRs), by country of birth for the 2004-2012 period, 2) The proportions in each immigrant group that arrive without children, and, 3) Of those childless at arrival the proportions of women who go on to have births within a short period of arrival. Next, we compare the ASFRs and TFR for Polish migrant women with those observed in Poland. Our results show that the fertility of Polish migrants is amongst the lowest for all population subgroups in the UK, and that Polish migrants are less likely to have children soon after arrival than other immigrant groups. The findings are consistent with migration not being so closely linked to family formation for Polish migrants as it is for immigrants in the comparison groups. We also find that the fertility patterns of Polish migrants are different to those observed in Poland with a later childbearing profile and a slightly higher TFR

Central bank design in general equilibrium

We study the effects of alternative institutional arrangements for the determination of monetary policy in the context of a capital-theoretic, general equilibrium economy. In the absence of an institutional arrangement, there is a continuum of steady state equilibria indexed by rates of inflation ranging from the Friedman rule to high a high level. The social optimum is associated with the Friedman rule.. We consider three institutional arrangements for determining monetary policy. The first, unconditional majority voting, always leads to a substantial inflation bias. The second, a simple form of bargaining which we interpret as a policy board, generally improves on the unconditional majority voting outcome. Finally, we consider a form of constitutional rule which always achieves the social optimum.Monetary theory ; Banks and banking, Central

The Bible in the Bowls

The Bible in the Bowls represents a complete catalogue of Hebrew Bible quotations found in the published corpus of Jewish Babylonian Aramaic magic bowls. As our only direct epigraphic witnesses to the Hebrew Bible from late antique Babylonia, the bowls are uniquely placed to contribute to research on the (oral) transmission of the biblical text in late antiquity; the pre-Masoretic Babylonian vocalisation tradition; the formation of the liturgy and the early development of the Jewish prayer book; the social locations of biblical knowledge in late antique Babylonia and socio-religious typologies of the bowls; and the dynamics of scriptural citation in ancient Jewish magic. In a number of cases, the bowls also contain the earliest attestations of biblical verses not found in the Dead Sea Scrolls. Pre-dating the next available evidence by four to five centuries, the bowls are a valuable resource for biblical text critics. By making these valuable witnesses to the Hebrew Bible easily available to scholars, The Bible in the Bowls is designed to facilitate further research by linguists, liturgists, biblical text critics, and students of Jewish magic. It collates and transcribes each biblical verse as it appears in the published bowls, furnishes details of the bowls’ publication, and notes various features of interest. The catalogue is also accompanied by an accessible introduction that briefly introduces the incantation bowls, surveys their deployment of scripture in light of their magical goals, and discusses the orthography of the quotations and what this can tell us about the encounter with the biblical text in late antique Babylonia
