Their doores citations are counted only for the first article. Her geographical areas of research, besides Panama and Central America in general, include Peru and Israel.

Latin American Antiquity 7 4, Ever-improving analytic methods for retrieving empirical data from archaeological sites, together with advances in genetic, genomic, and experimental research on living crops and their wild ancestors are providing new understandings of, and mechanisms for domestication and early agriculture see discussion under Research Focus.

In the next 10 years, Piperno would like to extend the utility of phytoliths, she says.

They also examined modern starch grains from a much larger set of economic plants so that they could be more sure of the archaeological starch grain identifictions. This is a Profile of a recently elected member of the National Academy of Sciences to accompany the member’s Inaugural Article on page Independent beginnings of agriculture occurred between 12, and 10, years ago in a number of world regions, including the American tropics, southwest Asia, and China.

The data indicated that the human population density there was higher than previously assumed and was supported by earlier and more sophisticated systems of agriculture than had been imagined.

At the same time, ongoing studies of phytoliths from tropical plants and sediments are discovering new Experimental study of growth and phenotypic variability in Late Pleistocene and early Holocene environments.

In the s, John Doebley and his team from the University of Wisconsin Madison, Pipern produced molecular evidence showing that the tropical Central Balsas watershed of Mexico, a not arid, high elevation region, was probably the cradle of maize domestication She is best known for her pioneering research on the analysis of phytoliths — the microcopic silica bodies that occur in many plant species – particularly in relation to the origins of agriculture in lowland Central America.

Support Center Support Center. Phytolith analysis is now sufficiently mature to provide an independent source of data in tropical paleoethnobotany and paleoecology. Their analyses of phytoliths and pollen from the lake cores found the same kinds of environmental shifts as in other regions of the lowland tropics, with a rapid and marked transition to the present warmer, wetter climate taking place at the end of the Ice Age approximately 10, years ago 5.

The Origins of Agriculture in the Lowland Neotropics. Here we report the occurrence of starch grains identifiable as manioc Manihot esculenta Crantzyams Dioscorea sp. Paleoecological data from two sites in central Pacific Panama have allowed the reconstruction of Late Pleistocene climate and vegetation in lowland areas, the timing of important environmental changes, and the generation of predictions concerning Paleoindian settlement and subsistence.

The phytolith evidence more. Help Center Find new research papers in: To fill this gap, Piperno explored a new direction in tropical research called starch grain analysis. They have included study of phytoliths, starch grains and pollen at archeological sites in Panama, Mexico, Ecuador, Peru, and Israel.

Profile of Dolores R. Piperno

In the late s and piprrno s, Piperno continued her collaboration with Bush and Colinvaux with more work on sediment cores from lakes. Correlation of reconstructed environmental setting with Paleoindian site location suggests that Clovis adaptations were fluid and flexible, and utilized a wide variety of vegetation types.

The results verified the first set of starch data, providing evidence for an early use of manioc and yams, and corroborated previous phytolith data for maize Paleoecological data from two sites in central Pacific Panama have allowed the dklores of Late Pleistocene climate and vegetation in lowland areas, the timing of important environmental changes, and the generation of predictions Proceedings of the National academy of Sciences 2, Forests, however, were widespread in extent and many lowland forest taxa apparently persisted, creating the basis for the rejection piiperno refugial theory as an explanatory model for early human occupation.

Special Issue of Current Anthropology. At the same time, ongoing studies of phytoliths from tropical plants and sediments are discovering new applications. This date for maize cultivation is more than 2, years earlier than any previously reported from the Pipeeno basin2.

Patterns, Process, and New Developments. Published online Pipsrno A few kernels short of a cob: A re-evaluation in consideration of the empirical evidence, Meanwhile, she published a new edition of her phytolith book last year, in which she reviewed the present state of knowledge about the discipline and the growth of the field since 3.

The middle child of three, Piperno enjoyed reading science and history books and playing sports, such as golf, tennis, and softball. My research interests have mainly involved the archaeology and human ecology of the lowland American tropics together with the biogeographical and climatological history of the tropical biome.
