Abstract
Elemental analyzer (EA) Isotope Ratio Mass Spectrometry was used to measure ∂13C values on soil organic matter from reservoirs and depressions at the ancient Maya urban centers of Tikal, Guatemala and Yaxnohcah, Mexico. Variation in δ13C values on soil organic matter were > −2.0‰, which suggests enrichment from C4 plants including maize, other tropical grasses (Poaceae), and tropical sedges (Cyperaceae), CAM plants (Clusia sp.), and cyanobacteria (blue-green algae). Cyanobacteria were likely a major contributor to the 13C enrichment of soil organic matter in Maya reservoirs and depressions, which has obfuscated our understanding of ancient Maya maize production. It is possible that the Maya used cyanobacteria as a fertilizer, which enriched agricultural field soil organic matter.
期刊介绍：
Published quarterly, this is the only general journal dedicated solely to North America—with total coverage of archaeological activity in the United States, Canada, and Northern Mexico (excluding Mesoamerica). The North American Archaeologist surveys all aspects of prehistoric and historic archaeology within an evolutionary perspective, from Paleo-Indian studies to industrial sites. It accents the results of Resource Management and Contract Archaeology, the newest growth areas in archaeology, often neglected in other publications. The Journal regularly and reliably publishes work based on activities in state, provincial and local archaeological societies.
