Southeastern North America

There are other milder forms of thederiasis that resemble the disease caused by T parva infection. They also primarily affect catde and are transmitted by ticks. Causative organisms iaclude Theileria annulata responsible for tropical thieleriasis, tropical piroplasmosis, Egyptian fever, and Mediterranean Coast fever. These affect ox, zebu, and water buffalo. Endemic areas iaclude northern Africa, southeastern Europe, the southern part of the former USSR, and Asia. Theileria mutans is the cause of benign bovine thieleriasis, Marico calf disease, and mild gad sickness. It affects ox and zebu ia Africa, Asia, southern Europe, England, the former USSR, AustraUa, and North America. 

As treated in other chapters of this book, air masses often transport acidic pollutants thousands of kilometres from their original source prior to deposition. Because air mass and storm movements tend to follow regular patterns, there is a strong linkage between the sources of pollutants and the areas that receive the acidic deposition. In eastern North America, the air mass movements and storm tracks are, on the average, from southwest towards the northeast. This serves to carry the emitted pollutants from the industrial "heartland over the more rural and comparatively pristine area of the northeast United States and southeastern Qmada (14). The spatial distribution of sulphate deposition over the eastern United States and Canada in 1980 is shown in Figure 4 (17).

It is the intent of this paper to explore the various control tactics that are being suggested in the management of bark beetles in the forest system with specific attention given to the potential impact on the predator population. Similar arguments could be extended to other bark beetle mortality agents such as the parasite community. Primary examples and control tactics discussed will be drawn from our experience with the southern pine beetle, I). frontalis, a major pest in the southeastern U.S., along with other bark beetles in North America. 

Uses Mirex is used in North America and in the southeastern United States for the control of fire and ants. Mirex is also effective against the hamster ant, the yellow-jacket, the Texas leaf-cutting ant, and the Hawaiian mealy bug. A ban on the use of mirex for pest control with exemptions was brought in on June 30, 1978. It has its use as a fire retardant in plastics, rubber, paint, paper, and electrical goods from 1959 to 1972 due to its high melting point and high chemical stability.14,48... 

Types of twined fabric structures composed of bast or phloem fibers and feathers were identified in prehistoric fabrics of southeastern North America by chemical and physical analyses and technical fabrication studies. Fabrics and either partially or completely mineralized pseudomorphs after fabric from the Tunacunnhee and Etowah sites in Georgia (dated respectively A.D. 150 95 years and about A.D. 1200) were examined. The work confirms the presence of at least two types of twined structures for the earlier Hopewell site and intricately constructed re-plied yarns and twined fabric for the later Mississippian one. The study of fabrics from both sites provides evidence of the kinds of materials produced and used by prehistoric peoples of the region during a 1000-year interlude. 

Fabrics used by the ABORIGINAL PEOPLE of southeastern North America have not been studied extensively. Small fragments of cordage, fabrics, and matting have been recorded from various prehistoric sites in the region (1-4), but analytical and synthesizing efforts have focused on matters other than the study of these pieces or the study of their cultural implications. Because fabrics are manufactured and used by people, their examination can reveal information about those who produced them. A first step, however, is the analysis of fabric as fabric. The purpose of this project is this first step to characterize selected examples of direct fabric evidence from the Tunacunnhee and Etowah sites in Georgia. 

Although both sites are in the same geographic area (Figure 1), they differ greatly in age and cultural expression. The Tunacunnhee site, dated A.D. 150 95 years, represents the Hopewell tradition (I), whereas Etowah, in use between A.D. 900 and A.D. 1400, is considered to be of the Middle Mississippian period (7). Taken together, the two sites and their fabrics provide evidence of the kinds of materials produced and used by certain prehistoric people of the region. Both sites are expressions of major cultural traditions in southeastern North America, and both contain direct fabric evidence. These facts underscore the importance of... 

The second example appears to be the same octagonal openwork as seen on the fabric bundle. It certainly resembles more closely the section of the Etowah bundle than other schematic illustrations (9,12,16). The intricately structured fabric bundle remains an example of high achievement in fabrics of the prehistoric peoples of southeastern North America. 

It is evident from the work completed, however, that direct fabric evidence, whether fabric or pseudomorph after fabric, contains much data about prehistoric fabrics of southeastern North America. The information gleaned from their study can be used to reconstruct the cultural implications of fabric manufacture and use among the prehistoric peoples of the region. 

Although exposure of most people to Psilocybe spp. is undoubtedly minimal, skin test reactivity to P cubensis spore extracts is the most significant of all basidiomycetes tested in Europe and the USA [20, 21]. This reactivity probably results from exposure to related species. P cubensis occurs naturally on the northeastern coast of South America, the Caribbean and the southeastern coast of North America. Although related species occur throughout the temperate northern hemisphere, the distribution of these mushrooms is probably less important clinically than the cross-reactivity patterns of its allergens. Several species in genera closely related to Psilocybe are common lawn... 

Magnolias occur in warm-temperate and subtropical climates of the Northern Hemisphere, particularly in southeastern North America and most diversely, eastern Asia. 

The tulip-tree (Liriodendron tulipifera) is another member of the magnolia family with a relatively wide distribution in southeastern North America. This species is commercially important for its straight, clear lumber, and as an ornamental tree. 

The southern maidenhair fern tends to be found on shady, moist slopes with calcium-rich soil in the Southeastern and Gulf states and the Rockies as far north as Utah and west to California. Northern maidenhair fern occurs most abundantly in Virginia, though scattered collections are known from other coastal areas, as well as from woodlands within North and South Carolina and Georgia, and as far north as Ontario. Western maidenhair is also known as five finger maidenhair, due to the appearance of the leaves at the ends of the stalks, and it is native to western North America. Species of maidenhair ferns can also be found in Europe, around the Mediterranean and in Japan. 

Black maple (A. nigrum) is rather similar in appearance to sugar maple, but its leaves have a more three-lobed appearance. Florida maple (A. barbatum) replaces the sugar maple in southeastern North America.
