Coexistence of congeneric native and invasive species: The case of the green algae Codium spp. in northwestern Spain

We examined the patterns of distribution and abundance, and reproductive traits (presence of gametophytes and size at time of reproduction) in the invasive Codium fragile ssp. fragile and the native C. tomentosum and C. vermilara on intertidal habitats of NW Spain at two dates. All three species coexist in the locations and habitats studied, although abundances were low. We found a greater proportion of C. fragile ssp. fragile towards the east of the Cantabrian coast and on upper levels on the shore, where conditions are more stressful. The proportion of thalli bearing gametangia in C. fragile ssp. fragile was greater than in the native species in all habitats. The presence of gametangia was size-dependent for all species, with the invasive species maturing at a smaller size, which combined with the previous features, might confer competitive advantages to this species over the native species. We also demonstrated that molecular analyses are necessary for the correct identification of C. fragile subspecies.

Religion, Violence and Cities

In exploring the connections between religion, violence and cities, the book probes the extent to which religion moderates or exacerbates violence in an increasingly urbanised world. Originating in a five year research project , Conflict in Cities and the Contested State, concerned with Belfast, Jerusalem and other ethno-nationally divided cities, this volume widens the geographical focus to include diverse cities from the Balkans, the Middle East, Nigeria and Japan. In addressing the understudied triangular relationships between religion, violence and cities, contributors stress the multiple forms taken by religion and violence while challenging the compartmentalisation of two highly topical debates – links between religion and violence on the one hand, and the proliferation of violent urban conflicts on the other hand. Their research demonstrates why cities have become so important in conflicts driven by state-building, fundamentalism, religious nationalism, and ethno-religious division and illuminates the conditions under which urban environments can fuel violent conflicts while simultaneously providing opportunities for managing or transforming them.

Religion, Violence and Cities: An Introduction

The catalyst for this special issue was a symposium entitled Religion, Violence and Cities, held under the auspices of a five year inter-disciplinary research project on ethno-nationally divided cities.

While this project expressly addressed cities divided by ethno-national conflict, it was clear from the beginning that there was an important religious dimension to such conflicts in most, if not all, the cities being studied.2 The rationale of the Special Issue is to examine how this religious dimension exacerbates (or moderates) urban violence within a broad comparative context. Although three of the following articles are informed by Project research, we draw the net wider to encompass a broader geographical spread from the Balkans, the Middle East, Nigeria and Japan.

Religion, anti-slavery, and identity: Irish Presbyterians, the United States, and transatlantic evangelicalism, c. 1820-1914

Scholars have devoted much attention to the causes and consequences of Presbyterian emigration from Ulster to the thirteen colonies before 1776. This article moves beyond the eighteenth century to examine the continued religious links between Presbyterians in Ireland and the United States in the nineteenth century. It begins with an examination of the influence of evangelicalism on both sides of the Atlantic and how this promoted unity in denominational identity, missionary activity to convert Catholics, and revivalist religion during the first half of the century. Though Irish Presbyterians had great affection for their American co-religionists, they were not uncritical, and significant tensions did develop over slavery. The article then examines the religious character of Scotch-Irish or Ulster-Scots identity in the late nineteenth century, which was articulated in response to the alleged demoralising influence of large-scale Irish immigration during and after the Famine of the 1840s, the so-called Romanisation of Catholicism, and the threat of Home Rule in Ireland. The importance of identity politics should not obscure religious developments, and the article ends with a consideration of the origins and character of fundamentalism, perhaps one of the most important cultural connections between Protestants in Northern Ireland and the United States in the twentieth century.

Northern Ireland: Religion, Religiosity and Politics in a Changing Society

The Handbook of Global Contemporary Christianity: Themes and Developments in Culture, Politics, and Society maps the transformations, as well as the continuities, of the largest of the major religions - engaging with the critical global issues which relate to the faith in a fast changing world. International experts in the area offer contributions focusing on global movements; regional trends and developments; Christianity, the state, politics and polity; and Christianity and social diversity. Collectively the contributors provide a comprehensive treatment of health of the religion as Christianity enters its third millennium in existence and details the challenges and dilemmas facing its various expressions, both old and new. The volume is a companion to the Handbook of Contemporary Global Christianity: Movements, Institutions, and Allegiance.
