AbstractThis paper outlines the known distribution of eight xeric grassland-adapted species of Lygaeidae, and examines these distributions with respect to the glacial history of North America during the Pleistocene, and past and present distribution of grassland vegetation. Four of these species (Neosuris castanea, Sisamnes claviger, Ligyrocoris latimarginatus, and Melanopleurus perplexus) probably survived the Pleistocene in refugia south of the Late Wisconsinan ice sheet. Differences in climatic requirements may explain the variations in geographic distribution exhibited by these four insects and a methodology for testing this is discussed. The four other species (Crophius ramosus, Kolenetrus plenus, Slaterobius insignis, and Emblethis vicarius) may have occurred in the north prior to 1.2 mya and survived the Late Pleistocene in both the northern Beringian refugium and in southern refugia. Molecular systematics, especially use of DNA restriction site or sequence data, might provide the evidence needed to test historical biogeographic postulates based on the extant distribution of these species.

Religion shaped the early modern Atlantic world in many ways. Although Iberian expansion began before the Protestant Reformation, Europe soon divided between Protestant and Catholic, and this division created a context for European understandings of the purpose of expansion. With permission from the pope to evangelize outside the Old World, the Spanish and the Portuguese split the extra-European world between them; Spain was responsible for most of the Americas (excluding only the area that would become Brazil), while Portugal took Brazil and Africa (as well as Asia). Soon representatives of each kingdom were at work, conquering, colonizing, and evangelizing. Protestantism, although it arrived late in the contest for colonies and trade in this New World, was central to Spanish understanding of its work; evangelizing the native peoples of the Americas would add additional souls to the church, making up for those who had been lost to the Protestant Reformation. When Protestants finally became involved in colonizing the Americas and trading with Africa, they similarly understood their role as combating the reach and influence of their Catholic rivals. If in 1600 the European presence outside of Europe was overwhelmingly Catholic, by 1700 a map of the spread of Christianity showed varied results. Spain controlled the central area of the Americas, including much of South America and the Caribbean, all of Central America, and all the southern area of North America (from Florida and New Mexico south). Portugal had Brazil, while Catholic France held Quebec to the north and selected islands in the Caribbean. The Protestant presence was predominantly British, and included eastern North America between Quebec and Florida as well as some islands in the Caribbean. The Protestant Dutch also held island colonies and a South American outpost. West Africa and West Central Africa hosted trading forts controlled by most of these European powers, from which were shipped slaves as well as trade goods. The religious rivalries of early modern Europe had been effectively exported. Every faith represented along the shores of the Atlantic prior to contact would participate in the intermixing that occurred afterward. The history of religion in the Atlantic world therefore explores the variety of traditions within that world and the effects of the circulation, transplantation, and encounter of these various faiths.

With frequent host shifts involving the colonization of new hosts across large geographical ranges, crop pests are good models for examining the mechanisms of rapid colonization. The microbial partners of pest insects may be involved or affected by colonization, which has been little studied so far. We investigated the demographic history of the rosy apple aphid, Dysaphis plantaginea, a major pest of the cultivated apple (Malus domestica) in Europe, North Africa and North America, as well as the diversity of its endosymbiotic bacterial community. We genotyped a comprehensive sample of 714 colonies from Europe, Morocco and the US using mitochondrial (CytB and CO1), bacterial (16s rRNA and TrnpB), and 30 microsatellite markers. We detected five populations spread across the US, Morocco, Western and Eastern Europe, and Spain. Populations showed weak genetic differentiation and high genetic diversity, except the Moroccan and the North American that are likely the result of recent colonization events. Coalescent-based inferences releaved high levels of gene flow among populations during the colonization, but did not allow determining the sequence of colonization of Europe, America and Morroco by D. plantaginea, likely because of the weak genetic differentiation and the occurrence of gene flow among populations. Finally, we found that D. plantaginea rarely hosts any other endosymbiotic bacteria than its obligate nutritional symbiont Buchnera aphidicola. This suggests that secondary endosymbionts did not play any role in the rapid spread of the rosy apple aphid. These findings have fundamental importance for understanding pest colonization processes and implications for sustainable pest control programs.

AbstractFossils from sites of Late Quaternary age in North America provide tangible evidence of temporal changes in the character of the northern beetle fauna. Based on a synthesis of the fossil data with analyses of the present distributions for northern species, a rudimentary model is proposed to explain the recent history of the fauna of the arctic and the boreal forest.An open-ground beetle fauna of arctic–subarctic affinities had become established along the southern margin of the Laurentide ice sheet in the midcontinent by 20 500 years before present (yr B.P.). Climatic warming decimated this fauna throughout lowland areas at some time between 16 700 and 15 300 yr B.P.; small populations of some arctic–subarctic species, however, survived within either alpine habitats of the Cordillera and Appalachians or specialized environments associated with stagnant ice.Populations of the same arctic–subarctic beetle species existed within the ice-free Alaska–Yukon refugium throughout the late Wisconsinan. During the Holocene, this region served as the principal centre-of-origin for the dispersal of the arctic–subarctic beetle fauna.The beetle fauna of the boreal forest was also displaced southward by Late Wisconsinan glaciation. By 15 300 yr B.P., however, this fauna had largely replaced the arctic–subarctic beetle fauna along the ice margin of the midcontinent. Evidence provided by fossils from a series of sites demonstrates that beetle species of the boreal forest dispersed northward into Canada as the ice front receded.

AbstractThe Scandinavian scientist-mystic Emanuel Swedenborg (1688-1772) has had a curious relationship to the history of how Western literature has responded to Buddhism. Since Honoré de Balzac’s claim in the 1830s that Swedenborg was “a Buddha of the north,” Swedenborg’s mystical teachings have been consistently aligned with Buddhism by authors on both sides of the pacific, from D. T. Suzuki to Philangi Dasa, the publisher of the first Buddhist journal in North America. This essay explores the different historical frames that allowed for this steady correlation, and argues that the rhetorical and aesthetic trope of “Swedenborg as Buddha” became a point of cultural translation, especially between Japanese Zen and twentieth-century Modernism. Swedenborg’s figuration in the earlier work of Ralph Waldo Emerson and William Blake, moreover, might begin to account for the peculiar ways those two Romantics have particularly affected modern Japanese literature. The transpacific flow of these ideas ultimately complicates the Orientalist critique that has read Western aesthetic contact with Buddhism as one of hegemonic misappropriation.

The literature on Calanus finmarchicus (Gunnerus) in arctic-subarctic Canada is reviewed, and the history of the 2-size-group phenomenon in the North Atlantic subarctic region is discussed. Calanus glacialis Jaschnov is briefly described, and compared with material from North America, the characters emphasized being size and the structure of the fifth legs. It is concluded that specimens from arctic and subarctic North America agree essentially with C. glacialis, those from the subarctic and north boreal regions with C. finmarchicus. Occurrence of the 2 species in northern North America is given, that of the large glacialis alone being shown to coincide closely with the known extent of unmixed polar water, of the 2 together to occupy the region of mixed polar and Atlantic water, and of the small finmarchicus alone to inhabit Atlantic water.

The systematics of Diplostomum species, common intestinal parasites of piscivorous birds, has long been problematic, owing to phenotypic plasticity and the paucity of morphological features that are often subject to age- and host-induced variation. We sequenced the ITS1–5.8S–ITS2 regions of the rDNA from adult Diplostomum huronense, Diplostomum indistinctum, and Diplostomum baeri obtained from experimentally infected ring-bill gulls (Larus delawarensis) and compared them with partial ITS1 sequences from several species of Diplostomum in GenBank. The three North American species were distinguishable on the basis of ITS sequences. Sequences from D. huronense differed from those of D. indistinctum at 12 sites in ITS1 and 4 sites in ITS2, supporting morphological and morphometric data that indicate the two are distinct species. Sequences of D. huronense and D. indistinctum differed from those of D. baeri at 27 and 24 sites, respectively, in ITS1 and 15 and 12 sites, respectively, in ITS2. Phylogenetic analysis of partial ITS1 sequences revealed that the North American and European species of Diplostomum formed separate groups, with the former being basal to the latter. The results indicated that D. huronense and D. indistinctum from North America are distinct from Diplostomum spathaceum and other similar species from Europe. Furthermore, sequences from specimens identified as D. baeri from North America differed from those of D. baeri from Europe by 3.8% in ITS1 (23 sites). While morphologically similar, the two are not conspecific. Sequences of the North American species have been deposited in GenBank (AY 123042–123044).
