Leishmania isoenzyme polymorphisms in Ecuador: Relationships with geographic distribution and clinical presentation

BACKGROUND Determinants of the clinical presentation of the leishmaniases are poorly understood but Leishmania species and strain differences are important. To examine the relationship between clinical presentation, species and isoenzyme polymorphisms, 56 Leishmania isolates from distinct presentations of American tegumentary leishmaniasis (ATL) from Ecuador were analyzed. METHODS Isolates we...

The Microscope of Comparative Psychoanalysis and the Macrosociety

“The struggle for land ownership, which is assuming increasingly more drastic form throughout all of Latin America, is now beginning even in the Andean highlands of Ecuador. The indios of the Sierra in Bolivia, Peru, and Ecuador, in each of which they make up approximately half the population, are generally considered to be barely capable of development. Centuries of oppression and dependence h...

A new disjunct Dendrothrix (Euphorbiaceae, tribe Hippomaneae): a Guiana Shield element in sub-Andean cordilleras of Ecuador and Peru

Dendrothrix condorensis K.Wurdack, sp. nov. from the sub-Andean cordilleras of Ecuador and Peru is described and illustrated. The new species is geographically widely separated from its likely closest relative, D. yutajensis, which is endemic to the Guiana Shield region of southern Venezuela and adjacent Brazil, and notably differs in leaf morphology. Vegetative (i.e., epidermal micropapillae, ...

Spatial and Temporal Scales of Range Expansion in Wild Phaseolus vulgaris

The wild progenitor of common-bean has an exceptionally large distribution from northern Mexico to northwestern Argentina, unusual among crop wild progenitors. This research sought to document major events of range expansion that led to this distribution and associated environmental changes. Through the use of genotyping-by-sequencing (∼20,000 SNPs) and geographic information systems applied to...
