Comparative morphological and palynological studies have been carried out on Plantago fastigiata (P. insularis) of the New World and P. ovata, including some closely allied species of section Leucopsyllium, of the Old World. As a result, P. fastigiata is regarded as conspecific with P. ovata. It is postulated that the North American populations known as P. fastigiata are introductions of P. ovata dating from the late 18th and the beginning of the 19th century by early settlers in California.

Abstract This article contributes to our knowledge of two early phases in the history of household economics. The first is represented by the 19th-century theory of Alfred Marshall and the second by the interwar theories of several North American consumer economists (Hazel Kyrk, Elizabeth Hoyt, and Margaret Reid). The aim is to present the analytical focus and accounts of social good that animated these phases. Since Marshall’s focus was on improving industrial production, his family economics explained how the Victorian family could improve the labour it contributed to industry. But the North American consumer economists sought to improve family consumption. Regarding ethics, 19th-century families were to cultivate an industrious and altruistic character. But the consumer economists thought families needed protection from producer fraud, along with living standards that expressed their individuality. Early household economics also accepted the gendered family form that had accompanied these developments, rejecting more ‘activist’ conceptions.

The North

The genus Carphoborus is widely distributed in the Holarctic realm. It occurs from the northern limits of tree growth south in the Old World to India and northern Africa and in the New World to Baja California, New Mexico, Mississippi, and Florida.All of the North American species breed in the inner bark of coniferous trees of the genera Pinus, Picea, and Pseudotsuga. Branches that are being shaded out or are broken, but still hanging in the tree, are generally preferred for the construction of galleries. A few species have been reported from slash; however, they are usually not aggressive or abundant enough to survive in competition ivith other bark beetles normally found in slash. The economic importance of the genus is not great; the hahit of breeding in the unthrifty lower branches of coniferous trees contributes slightly toward accelerating the natural pruning of the trees and consequently aids in the production of a higher quality of timber.

And Function

It is generally accepted that the specialized agricultural implements and techniques, and domesticated plants (with a few possible exceptions) of the Old and New Worlds are unrelated and independently developed. Parallel developments in agricultural accessories have occurred; the hoe and irrigation are obvious exemplars. The hand sickle, used to harvest cereal crops in the Old World, and to cut wild grasses in the New World, may now be pointed out as occurring in both hemispheres. The forms, materials, and function of the Old World sickle distinguish it from that of the New World, and it would appear that there is no specific connection between the Afro-Asian sickle used in farming and its North American counterpart used predominantly by incipient or non-agricultural native groups.

Syllophopsis  sechellensis  (Emery)  (formerly  Monomorium  sechellense) (Hymenoptera: Formicidae) is a small, inconspicuous ant species native to the Old-World tropics. Syllophopsis sechellensis is widespread in Asia and Australia, and on islands the Indian, Pacific, and Atlantic Oceans. In the New  World,  all  published  records  come  from  West  Indian  islands.  Here,  I report the first records of S. sechellensis from North America: from four sites in Miami-Dade and Broward counties, Florida, more than 1500 km from the closest records in the West Indies. The ants of Florida have been well-studied in the past, so S. sechellensis appears to be a recent arrival.

Area Of Origin

African machairodont specimens previously referred to three species of Megantereon are considered to represent a single species in turn argued to be conspecific with the Eurasian species Megantereon cultridens (Cuvier). The area of origin of Megantereon remains unclear, but doubt is expressed about claims for an earliest appearance of the genus in North America. It is probable that the North American species M. hesperus is a junior synonym of M. cultridens.

Several museums and libraries in North America and Europe house in their collections expressive works of art from Latin America. An understanding of the source of such collections requires study of their history and of the background from which they come, even if, as a matter of fact, collecting works of art and bibliographical assets on such a theme is not new. The interest in studying artworks which do not belong to the so-called western canon enables a wider knowledge of the art in Latin America. Notwithstanding the reasons behind such interest, it is worth noting that some facts related to their development are still lively, such as the interests roused by the travelling artists in the 19th century, who departed in search of the unknown or exotic and came back to their homeland with an imagination full of images from the New World. It is undeniable that Latin America has had a key role in the major changes that occurred during the age of discovery, when Europe focused on its colonies. Nowadays, as we observe the recurrence of such a foreign look at Latin America, we might ask ourselves how Latin America sees itself.

Order Of Magnitude

Analysis of banding sequences of polytene chromosomes in Palearctic (Russian) and Nearctic (North American) Chironomus entis shows strong karyotype divergence between populations on the two continents. Four out of seven chromosomal arms in the North American C. entis karyotype are characterized by sequences found only in the Nearctic. In total, 44 banding sequences are now known for this species across the Holarctic, including 22 exclusively Palearctic, 6 Holarctic, and 16 exclusively Nearctic sequences. The degree of cytogenetic differentiation between Palearctic and Nearctic C. entis populations is an order of magnitude greater than differentiation among populations within either continent, but is only one third as great as the cytogenetic distance between the sibling species C. entis and C. plumosus. C. entis is the only sibling species of C. plumosus uncovered during cytological identification of Chironomus species from more than 50 North American lakes, indicating that the plumosus sibling-species group is much smaller in the Nearctic than in the Palearctic, where a dozen sibling species are known. Cytogenetic distance values calculated between Nearctic and Palearctic representatives of both C. entis and its sibling species C. plumosus are similar, but result from different patterns of karyotype divergence. New World C. entis is distinguished from Old World populations by the 16 uniquely Nearctic sequences, four of which occur in the homozygous state. In contrast, North American C. plumosus has fewer uniquely Nearctic sequences, and only one that occurs as a homozygote. However, four chromosomal arms in C. plumosus that are polymorphic in the Palearctic show fixation, or near fixation, of Holarctic sequences in the Nearctic C. plumosus karyotype. Thus, both the fixation of Holarctic sequences, and the occurrence or fixation of distinctly Nearctic sequences, contribute significantly to karyotype divergence. Patterns of karyotype divergence in Palearctic and Nearctic populations of different Holarctic chironomid species are discussed relative to intercontinental cytogenetic differentiation in other dipterans.Key words: karyotype, inversion polymorphism, cytogenetic divergence, Chironomus.

AbstractA carved sacrum from a fossil camelid was found near Tequixquiac in 1870 in Upper Pleistocene deposits of the Valley of Mexico. At that time it was described as one of the first discoveries that proved the co-existence of man with extinct fauna in the New World. The specimen was apparently lost at the end of the 19th century and serious doubts have been expressed about its authenticity. This carved bone was rediscovered in 1956, and recent studies of the specimen tend to demonstrate its authenticity and scientific value. A survey of all known examples of similar finds in North America suggests that the Tequixquiac bone is probably the only example of true art that has yet been found in Paleo-Indian levels in the New World.

"Keeping freshly alive the memories," was how the American daguerreotypist Marcus Aurelius Root summed up the guiding principle of the still young portrait photography in 1864. Until the middle of the 19th century, this principle was often associated with miniature painting in North America. This served as a crucial material aesthetic and iconographic reference for memory and grief photography. However, photography was able to assert itself through painting with a higher sharpness and the impression of a direct presence of the portrayed. At the center of the book are discourses on the materiality and mediality of the memory images in the context of local mourning and memorial traditions. Patrizia Munforte examines the interrelations between portrait photography and painting in North American visual culture after 1800.
