This paper is based almost entirely on material in the Canadian National Collection. It proposes several taxonomic changes, which are detailed in the summary that concludes the paper. It outlines the Canadian and Alaskan distribution of the forms considered and is, perhaps, justified by the paucity of published records of distribution in the more northern regions. The records for Hippodamia are based on more than 2,000 specimens that were identified by de Ruette; these records supplement those of Chapin (1946, Smithsonian Misc. Coll. 106(11): 1-39), who revised the New World forms of the genus and mapped their distribution in the United States.

People have been eating eggs for centuries. Records as far back as 1400 BC show that the Chinese and Egyptians raised birds for their eggs. The first domesticated birds to reach the Americas arrived in 1493 on Christopher Columbus' second voyage to the New World. Most food stores in the United States offer many varieties of chicken eggs to choose from — white, brown, organic, cage free, vegetarian, omega-3 fatty acid enriched, and more. The bottom line is that buying eggs is not as simple as it used to be because more choices exist today. This 4-page fact sheet will help you understand the choices you have as a consumer, so you can determine which variety of egg suits you and your family best.

The Gulf crisis 1990-1991 is one of the important historical events of the 1990s, which gave rise to the new world order by the sovereignty of the United States of America on this system. The Gulf crisis was an embodiment to clarify the features of this system. .     The crisis in the Gulf was an opportunity for the Moroccans to manage this complex event and to use it for the benefit of the Moroccan situation. Therefore, the bilateral position of the crisis came out as a rejection, a contradiction and a supporter of political and economic dimensions at the external and internal levels. On the Moroccan situation, and from these points came the choice of the subject of the study (the dimensions of the Moroccan position from the Gulf crisis 1990-1991), which shows the ingenuity of Moroccans in managing an external crisis and benefiting from it internally.

AbstractExtensive collections of synanthropic fly parasitoids in animal excrement accumulations in the United States, Mexico, Costa Rica, Puerto Rico, Uruguay, Chile, Denmark, Israel, and South Africa yielded seven forms of a Muscidifurax complex which were totally or partially reproductively isolated. Morphological studies of female and male parasitoids coupled with biological and zoogeographical information permitted the identification of five sibling species. Muscidifurax raptor Girault and Sanders 1910 is redescribed and four additional species are described as new: M. zaraptor, from the southwestern United States; M. raptoroides from Central America and Mexico; M. uniraptor from Puerto Rico, and M. raptorellus from Uruguay and Chile. Biological notes are added to the descriptions, and it was postulated that the genus is undergoing a process of speciation with local populations slowly becoming reproductively isolated and eventually giving rise to morphologically distinguishable entities. Most evidence suggests the establishment of Muscidifurax in the New World, concomitant with or shortly following the establishment of muscoid flies in accumulated excrement. Scanning electronmicroscopy was used in the analysis of some morphological structures.

In his essay on Tocqueville and Latin America Claudio López-Guerra asserts that, according to Alexis de Tocqueville, in the XIXth century Mexico and the United States had the same social state but not the same mores. The contention that follows is that religion (Catholicism v. Protestantism) is more important than equality in shaping the mores of a democratic people. In Democracy in America Tocqueville asserted: “It is true that the Anglo-Americans brought equality of conditions with them to the New World. There were neither commoners nor nobles there, and professional prejudices were always as unknown as prejudices of birth.

A new order for the New World was unfolding in the early nineteenth century, or so many in the United States believed. Between 1808 and 1825, all of Portuguese America and nearly all of Spanish America broke away from Europe, casting off Old World monarchs and inaugurating home-grown governments instead. People throughout the United States looked on with excitement, as the new order seemed at once to vindicate their own revolution as well as offer new possibilities for future progress. Free from obsolete European alliances, they hoped, the entire hemisphere could now rally together around republican government and commercial reciprocity. Statesmen and politicians were no exception, as men from Thomas Jefferson and James Monroe to John Quincy Adams and Henry Clay tried to exclude European influence from the hemisphere while securing new markets for American manufactures and agricultural surplus.

Cynipidae (Hymenoptera: Cynipoidea) is a diverse group of wasps, many of which are capable of inducing plants to make novel structures, galls, that protect and nourish the wasps' larvae. Other cynipids, especially those species in Ceroptresini and Synergini, are understood to be usurpers of galls made by other cynipids. The North American cynipid fauna has not been fully cataloged since 1979, but there is renewed interest in revising the taxonomy and in doing research that sheds light on the mechanisms of gall induction, the evolution of this life history, and their ecological interactions more broadly. Significant taxonomic changes have impacted the group since 1979, thereby warranting a new catalog. The current state of knowledge of species classified in Aulacideini, Ceroptresini, Diastrophini, Diplolepidini, Phanacidini, and Synergini in the United States, Canada, and Mexico is summarized in catalog format. We report 323 names, including 170 valid species of rose gall wasps, herb gall wasps, and inquiline gall wasps, classified in 12 genera, from the United States, Canada, and Mexico. Current taxonomic status, distribution, host associations, and vernacular names are listed for each species. The catalog also includes the original description of galls for many species of gall-inducer, as well as atomized characterizations of different gall traits as key-value pairs. For most galling species without existing vernacular names, new vernacular names are proposed.

Abstract The increased U.S. natural gas price volatility since the mid-to-late-1980s deregulation generally is attributed to the deregulated market being more sensitive to temperature-related residential demand. This study therefore quantifies relations between winter (November–February; December–February) temperature and residential gas consumption for the United States east of the Rocky Mountains for 1989–2000, by region and on monthly and seasonal time scales. State-level monthly gas consumption data are aggregated for nine multistate subregions of three Petroleum Administration for Defense Districts of the U.S. Department of Energy. Two temperature indices [days below percentile (DBP) and heating degree-days (HDD)] are developed using the Richman–Lamb fine-resolution (∼1° latitude–longitude) set of daily maximum and minimum temperatures for 1949–2000. Temperature parameters/values that maximize DBP/HDD correlations with gas consumption are identified. Maximum DBP and HDD correlations with gas consumption consistently are largest in the Great Lakes–Ohio Valley region on both monthly (from +0.89 to +0.91) and seasonal (from +0.93 to +0.97) time scales, for which they are based on daily maximum temperature. Such correlations are markedly lower on both time scales (from +0.62 to +0.80) in New England, where gas is less important than heating oil, and on the monthly scale (from +0.55 to +0.75) across the South because of low January correlations. For the South, maximum correlations are for daily DBP and HDD indices based on mean or minimum temperature. The percentiles having the highest DBP index correlations with gas consumption are slightly higher for northern regions than across the South. This is because lower (higher) relative (absolute) temperature thresholds are reached in warmer regions before home heating occurs. However, these optimum percentiles for all regions are bordered broadly by surrounding percentiles for which the correlations are almost as high as the maximum. This consistency establishes the robustness of the temperature–gas consumption relations obtained. The reference temperatures giving the highest HDD correlations with gas consumption are lower for the colder northern regions than farther south where the temperature range is truncated. However, all HDD reference temperatures greater than +10°C (+15°C) yield similar such correlations for northern (southern) regions, further confirming the robustness of the findings. This robustness, coupled with the very high correlation magnitudes obtained, suggests that potentially strong gas consumption predictability would follow from accurate seasonal temperature forecasts.

This chapter argues that the process by which Thomas Mann was canonized as the “greatest living man of letters” in the New World certainly had many similarities to his staging as a representative writer in the Old. But there were enormous differences as well, and these would turn out to be consequential for literary history, including literary history back in Germany. The chapter explains how Mann's rise to literary prominence in the United States took place within the larger context of a newly emerging and distinctively American cultural formation, the “middlebrow.” At first, this seems antithetical to Mann's associations with “serious” modern literature. However, the chapter reveals that modernism and the middlebrow have never truly stood in opposition to one another.
