Vultures comprise one of the most threatened groups of birds worldwide. With a total population not exceeding 6700 mature individuals, and in rapid decline across its range, the Andean Condor (Vultur gryphus) is listed as a Vulnerable species in the IUC
Soils-based evidence derived from thin section micromorphology is used to explore contrasts in pre-Hispanic and Hispanic arable land management practices associated with raised fields in an inter-Andean valley of Ecuador. Differences in textural
Hacienda Zuleta in the northern sierra province of Imbabura, Ecuador is the location of the largest 'ramp-mound' site of the Caranqui culture dated to the Late Period in the highlands chronological sequence (c. AD 1250-1525) and also of a large 17th-century Colonial period hacienda of Jesuit foundation. The Late Period is characterised by the construction of very large hemispherical or quadrilateral 'pyramid tolos, sometimes with a ramp or a long 'walkway' and up to 22 of these ramp-tola sites have been identified in the northern sierra provinces of northern Pichincha and Imbabura (Gondard & L6pez 1983; Knapp 1992). They are thought to have been the political centres of the region's paramount chiefs and the ceremonial foci for their scattered communities (Salomon 1986). Studies suggest they are contemporary with one another, originating from about the 8th to loth centuries AD (Athens 1978; 1992; Oberem 1975), although the phases of occupation associated with the creation of the large quadrilateral ramp mounds seem to be later, linked to socio-economic and political trends of agricultural intensification and increasing population densities which are also taken to characterize the Late Period.
