Phylogenetics, conservation, and historical biogeography of the West Indian members of the Adelieae (Euphorbiaceae)

The Caribbean Island Biodiversity Hotspot is the largest insular system of the New World and a priority for biodiversity conservation worldwide. The tribe Adeliae (Euphorbiaceae) has over 35 species endemic to this hotspot, representing one of the most extraordinary cases of speciation in the West Indies, involving taxa from Cuba, Hispaniola, Jamaica, and the Bahamas. These species form a monophyletic group and traditionally have been accommodated in two endemic genera: Lasiocroton and Leucocroton. A study based on: (1) scanning electron microscopy of pollen and trichomes, (2) macromorphology, and (3) molecular data, was conducted to reveal generic relationships within this group. Phylogenies were based on parsimony and Bayesian analyses of nucleotide sequences of the ITS regions of the nuclear ribosomal DNA and the non-coding chloroplast DNA spacers psbM-trnD and ycf6-pcbM. One species, Lasiocroton trelawniensis, was transferred from the tribe into the genus Bernardia. Of the remaining species, three major monophyletic assemblages were revealed, one was restricted to limestone ares of Hispaniola and was sister to a clade with two monophyletic genera, Lasiocroton and Leucocroton. Morphological, biogeographical, and ecological data provided additional support for each of these three monophyletic assemblages. The Hispaniolan taxa were accommodated in a new genus with four species: Garciadelia. Leucocroton includes the nickel hyperaccumulating species from serpentine soils of Cuba, while the rest of the species were placed in Lasiocroton, a genus restricted to limestone areas. The geographic history of the islands as well as the phylogenetic placement of the Leucocroton-alliance, allows the research to include the historical biogeography of the alliance across the islands of the Caribbean based on a dispersal-vicariance analysis. The alliance arose on Eastern Cuba and Hispaniola, with Lasiocroton and Leucocroton diverging on Eastern Cuba according to soil type. Within Leucocroton, the analysis shows two migrations across the serpentine soils of Cuba. Additional morphological, ecological, and phylogenetic analyses support four new species in Cuba (Lasiocroton gutierrezii) and Hispaniola ( Garciadelia abbottii, G. castilloae, and G. mejiae). ^

"To hold the world in contempt": The British Empire, war, and the Irish and Indian nationalist press, 1899–1914

The era between the close of the nineteenth century and the onset of the First World War witnessed a marked increase in radical agitation among Indian and Irish nationalists. The most outspoken political leaders of the day founded a series of widely circulated newspapers in India and Ireland, placing these editors in the enviable position of both reporting and creating the news. Nationalist journalists were in the vanguard of those pressing vocally for an independent India and Ireland, and together constituted an increasingly problematic contingent for the British Empire. The advanced-nationalist press in Ireland and the nationalist press in India took the lead in facilitating the exchange of provocative ideas--raising awareness of perceived imperial injustices, offering strategic advice, and cementing international solidarity. Irish and Indian press coverage of Britain's imperial wars constituted one of the premier weapons in the nationalists' arsenal, permitting them to build support for their ideology and forward their agenda in a manner both rapid and definitive. Directing their readers' attention to conflicts overseas proved instructive in how the Empire dealt with those who resisted its policies, and also showcased how it conducted its affairs with its allies. As such, critical press coverage of the Boxer Rebellion, Boer War, Russo-Japanese War, and World War I bred disaffection for the Empire, while attempts by the Empire to suppress the critiques further alienated the public. This dissertation offers the first comparative analysis of the major nationalist press organs in India and Ireland, using the prism of war to illustrate the increasingly persuasive role of the press in promoting resistance to the Empire. It focuses on how the leading Indian and Irish editors not only fostered a nationalist agenda within their own countries, but also worked in concert to construct a global anti-imperialist platform. By highlighting the anti-imperial rhetoric of the nationalist press in India and Ireland and illuminating their strategies for attaining self-government, this study deepens understanding of the seeds of nationalism, making a contribution to comparative imperial scholarship, and demonstrating the power of the media to alter imperial dynamics and effect political change.
