This volume is a monograph of the 47 species of the Dulcamaroid clade of the large and diverse genus Solanum. Species in the group occur in North, Central and South America, and in Europe and Asia. The group is most species-rich in Peru and Brazil, and three of the component species, Solanum laxum of Brazil, Solanum seaforthianum of the Caribbean and and Solanum crispum of Chile are cultivated in many parts of the world. All species are illustrated and a distribution map of each is provided. All names are typified and nomenclatural and bibliographic details for all typifications presented. One new species from Ecuador is described. The monograph is the first complete taxonomic treatment of these species since the worldwide monograph of Solanum done by the French botanist Michel-Felix Dunal in 1852.

Assessing Site Significance is an invaluable resource for archaeologists and others who need guidance in determining whether sites are eligible for listing in the National Register of Historic Places (NRHP). Because the register's eligibility criteria were largely developed for standing sites, it is difficult to know in any particular case whether a site known primarily through archaeological work has sufficient 'historical significance' to be listed. Hardesty and Little address these challenges, describing how to file for NRHP eligibility and how to determine the historical significance of archaeological properties. This second edition brings everything up to date, and includes new material on 17th- and 18th-century sites, traditional cultural properties, shipwrecks, Japanese internment camps, and military properties.

Documents the emergence of a pattern of political instability in Latin America. Traditional military coups have receded in the region, but elected presidents are still ousted from power as a result of recurrent crises. Aníbal Pérez-Liñán shows that presidential impeachment has become the main constitutional instrument employed by civilian elites to depose unpopular rulers. Based on detailed comparative research in five countries and extensive historical information, the book explains why crises without breakdown have become the dominant form of instability in recent years and why some presidents are removed from office while others survive in power. The analysis emphasizes the erosion of presidential approval resulting from corruption and unpopular policies, the formation of hostile coalitions in Congress, and the role of investigative journalism. This book challenges classic assumptions in studies of presidentialism and provides important insights for the fields of political communication, democratization, political behaviour, and institutional analysis.

"This book traces the history of rock 'n' roll in Mexico and the rise of the native countercultural movement La Onda (the wave). This story frames the most significant crisis of Mexico's postrevolution period: the student-led protests in 1968 and the government-orchestrated massacre that put an end to the movement".--BOOKJACKET.
