OBJECTIVE Primates were common in North America through most of the Eocene, but vanished in the Chadronian, about 35 million years ago. In the Arikareean, about 6 million years later, the enigmatic primate Ekgmowechashala appeared in the Great Plains and Oregon. This taxon shows little resemblance to other North American primates and its phylogenetic position has long been debated. New material...

First, we find that stock markets in Latin America, Eastern Europe and the Middle East, and Emerging Asia are sensitive to stock market activity of the G7 countries. However, the impact of the former on the G7 countries is much weaker at different time scales. In the same vein, the North America stock markets help to explain the evolution of returns in Latin America, Emerging Asia, the Far East...

The western north Atlantic Ocean constitutes a major route for autumnal migrants moving between eastern North America and the Caribbean or South America. Some shorebirds have long been known to use this route (Lincoln, 1939; Hagar, 1966; Palmer, 1968; McNeil and Burton, 1973), and recently Drury and Nisbet (1964) and Nisbet (1970) have stated that the Blackpoll Warbler (Dendroica striata) proba...

The Great Basin and Plateau encompass a vast region of western North America bracketed on the west by the Sierra Nevada and Cascade mountains and the east by the Rocky Mountains (Figure 1). The region is diverse but characterized by ecologically limiting, generally more arid conditions, and higher elevations than other parts of North America. It is also characterized by a type of archaeology th...
