Abstract The elm leaf beetle P. luteola is a serious pest of ornamental elms in most areas where they are grown. This insect is native to southern Europe and was introduced to the USA in the 1800s, but has also reached Central Asia, the Middle East, North Africa and South America and was recently detected in Australia. It feeds on all species of native and introduced elms, including American (Ulmus americana), English (U. procera), Chinese (U. parvifolia) and Siberian elm (U. pumila). Wu et al. (1991) identified elm leaf beetle as the second most important urban tree pest in the western United States and third most important nationally.

Two geographical types of pluvials are therefore to be distinguished: those of middle latitudes, which coincide with glaciations (North Africa, western United States, Iran, etc.) and those of low latitudes which, on the contrary, fall within the interglacial periods (Tricart, 1956, 167, translation).

Abstract A. areolatum is a basidiomycete that causes a white rot of a broad range of conifers. Its invasiveness arises from a symbiotic association with woodwasps of the genus Sirex. The species Sirexnoctilio is listed as "highly invasive" on the ISSG/IUCN website (ISSG, 2008) and is a Regulated Pest for the USA (APHIS, 2009a). The wasp and the fungus are native to Europe, North Africa and western Asia where their damage is considered secondary (Spradbery and Kirk, 1978). Introduced to areas of the Southern Hemisphere where exotic pine species are grown in plantations, these organisms have caused major losses. The insect invaded New Zealand by at least 1900, but did not cause serious concern until the 1940s (Talbot, 1977). It later spread to Tasmania and the southern parts of Australia and the wasp/fungus association was introduced into southern South America, beginning in Uruguay in 1980 (Ciesla, 2003). Invasion of South Africa occurred in 1994 (Tribe, 1995). Woodwasps are repeatedly detected in material imported to the USA, but were successfully excluded until 2004 (Wilson et al., 2009). The wasp and fungus were later found in nearby Canada (Ontario), although apparently due to a separate introduction (Bergeron et al., 2008; Wilson et al., 2009). Recent surveys found the wasp in four states of the USA (Evans-Goldner and Bunce, 2009) and 25 counties of Ontario in Canada (Shields, 2009). Schiff (2008) summarizes differences in complexity of the ecological situations in the Southern Hemisphere countries and North America that could affect spread and impact of the fungus and wasp.

AbstractThe discovery of fluted points at one site in the Andean Highlands near Quito, Ecuador, suggests that the fluted-point tradition extended into South America. The association of scrapers, knives, and gravers with the fluted points indicates a hunting assemblage which may be related to paleo-Indian horizons of western United States.

At the turn of the nineteenth and twentieth century a large group of Galician Ruthenians emigrated to North America and the United States and Canada, South America - mainly to Argentina and Brazil. Sheptytsky visited North America in 1910. He met with Ukrainian Greek Catholic immigrant communities in the United States and Canada. In 1921, he visited the USA and Canada again. In 1922 he arrived to Argentina and Brazil. He did not conduct open political agitation. However, some of his speeches have an anti-Polish character.

Mite Family

The oribatid mite family Zetomotrichidae is represented in warm regions of world, including Australia, South Africa, Mexico, South America and across the Palaearctic from southern Europe to Asia, but has been unreported from the USA and Canada. We describe a new zetomotrichid species, Ghilarovus robisoni n. sp., on the basis of adults, the first record of the genus and family from temperate North America. Specimens were collected from dry, usually rocky, vertical microhabitats in forests in southern USA. We provide a revised and expanded diagnosis for adults of Ghilarovus, discuss characters in Zetomotrichidae unique to the family, and provide a key to world Ghilarovus species.

Precipitation And Temperature

A 56-year time series of human plague cases ( Yersinia pestis ) in the western United States was used to explore the effects of climatic patterns on plague levels. We found that the Pacific Decadal Oscillation (PDO), together with previous plague levels and above-normal temperatures, explained much of the plague variability. We propose that the PDO's impact on plague is conveyed via its effect on precipitation and temperature and the effect of precipitation and temperature on plague hosts and vectors: warmer and wetter climate leading to increased plague activity and thus an increased number of human cases. Our analysis furthermore provides insights into the consistency of plague mechanisms at larger scales.

AbstractLichenostigma rugosa sp. nov. is reported from Europe, North Africa, Asia and the USA. Only one species of Lichenostigma, L. maureri, from Europe and Asia, was previously known. L. rugosa differs chiefly in having spores with deep irregular fissures. L. maureri is reported for the first time from South America (Argentina, Peru), the British Isles and Sweden.

AbstractCoccidioidomycosis is an infection caused by the geographically restricted dimorphic fungus, Coccidioides. Coccidioidomycosis occurs endemically in the southwestern and western United States, mainly in focused regions of Arizona and California where the incidence is highest, and in Central and South America. Patients with impaired immunity, especially those with impaired cellular immunity, are at higher risk of severe and disseminated disease. In this review, we describe the fungal ecology and mycology, epidemiology, pathophysiology, and normal immune defenses to Coccidioides as well as address current concepts in diagnosis, treatment, and continued care of patients with pulmonary coccidioidomycosis. We also present and answer our most frequently asked questions regarding patients with primary pulmonary coccidioidomycosis.
