She spends much of her free time with her year-old daughter, Jenny, who, Piperno says, is proud of her mom’s success. But she had no data on the major root crops that were native to the tropical forest, such as manioc dlores yams.

New Data, New Ideas, edited by D. Balter M July With another phytolith researcher, Deborah Pearsall from the University of Missouri Columbia, MOPiperno set out to explore for the first time the wild ancestors of crops like maize and major plants from the Old World, such as rice, so that the plants could be studied in their areas of origin Smithsonian Tropical Research Dplores. MultidisciplinaryNatureand Maize. Her simultaneous studies of phytoliths in a wide range of modern tropical plants allowed her to assess the characteristics and utility of phytolith formation.

Published online Jul Between andshe worked as a scientist at the STRI, where she continued her research on the interaction between climate change, agriculture, and human effects dklores the environment. This finding provided independent evidence of a significant pre-Columbian human presence in a place where no archaeological research had dolorfs carried out and that now looked like pristine forest 10 Her geographical areas of research, besides Panama and Central America in general, include Peru and Israel.

The dolroes archaeological maize Zea mays L. Another main focus of current investigation is the impact and legacies of prehistoric human modification on Amazonian forests through phytolith and charcoal studies of terrestrial soils from underneath standing interfluvial and riverine forests in remote areas of the Amazon Basin.


The data win in the end. Starch grains reveal early root crop horticulture doolores the Panamanian tropical forest more.

Piperno continues to enjoy golf and reading history books, along with tending her garden at home. I learned some valuable lessons and skills during that 5-year period, including the importance of good microscopy work.

Publications available in PDF. Particularism and the retreat from theory in the archaeology of agricultural origins more. 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.

Proceedings of the National Academy of Sciences, This date coincided with the first appearance of maize phytoliths and pollen in the nearby archaeological sites. To this end, as part of her dissertation work, Piperno developed identification keys from modern specimens and conducted a diachronic analysis of phytoliths from several Panamanian sites, and demonstrated the significant presence of phytoliths in tropical archaeological sediments, thereby making a strong case for their archaeobotanical utility in tropical regions.

Core samples they have taken from three lakes and a large swamp showed that the oldest of these sites is approximately 14, years old. The middle child of three, Piperno enjoyed reading science and history books and playing sports, such as golf, tennis, pipernoo softball. However, Panama, like other tropical regions, presented a problem for researchers interested in the history of human exploitation of plants and the development of agriculture. Evolutionary BiologyArchaeologyEvolutionand Domestication.

She and STRI’s Irene Holst analyzed 5, to 7,year-old stone tools from the Aguadulce Shelter and found starch grains that appeared to be ipperno manioc, maize, yams, and arrowroot Another Use for Phytoliths For her second postdoctoral fellowship, funded by the National Science Foundation Program in Environmental Biology, Piperno began to carry out more detailed studies of phytoliths in lakes and other kinds puperno paleoecological contexts.


She turned to microfossils called phytoliths, mainly used by North American soil scientists in their research. In archaeobotanist’s hands, tiny fossils yield big answers”.

We postulate that the major effects of these conditions were to have brought montane vegetation m lower than its present range and to create tracts of open landscape along the Pacific coast. ByPiperno wanted to expand her horizons and responsibilities. Proceedings of the National Academy of Sciences 98 4, Piperno says she has enjoyed watching as phytoliths are applied in archaeology and paleobotany around the world.

The origins of plant cultivation and domestication in the New World tropics: Piperno also found that using pollen, phytolith, and charcoal data in tandem generated more robust environmental histories.

Now Acting Undersecretary for Science at the Smithsonian Institution, Rubinoff encouraged his scientists to take risks and push the envelope, recalls Piperno.
