The mechanisms for the establishment of present-day vegetation during the early Holocene remain poorly understood in the Neotropics (American tropics), where paleoecological data are scarce and high biodiversity complicates forest dynamics. In Central America, understanding post-glacial forest expansion is further complicated by regional...
Observation of archaeological charcoal records from Maya sites, and in particular, the Classic site of Naachtun (Northern Peten, Guatemala), indicates that certain woody taxa tend to occur in proportions that are highly inconsistent with their representation in the local forests today. We note this phenomenon for two taxa in particular: 1) the...
We focus on pre-Columbian agricultural regimes in the Maya Lowlands, using new datasets of archaeological wood charcoal, seeds, phytoliths, and starch grains; biological properties of plants; and contemporary Indigenous practices. We address inherited models of agriculture in the lowlands: the limitations of the environment (finding more...
Pre-Columbian food production in the Maya Lowlands was long characterized as reliant on extensive, slash-and-burn agriculture as the sole cultivation system possible in the region, given environmental limitations, with maize as the dominant crop. While aspects of this "swidden thesis" of Maya agriculture have been chipped away in recent years,...

At the transition between the Maya lowlands and the highlands, the northern Alta Verapaz experimented major population movements following the abandonment of several cities as early as the 8th century onwards. This marked the start of what was referred to as the "Maya collapse", which would later extend to the entire lowlands until the 13th...
Botanical residues recovered from excavations in the Southeast Marketplace of Piedras Negras provide information about the healing and medical activities of the site's Classic period (a.d. 350-900) inhabitants, and point towards the intersection between commerce and medicine for the ancient Maya. The plants were likely exchanged at the market...
The Naachtun archaeological project started in 2010 with the aim of understanding the sociopolitical and economic history of one of the few Maya Classic capitals located in Northern Peten. Since 2013 a paleo-environmental team carried out a program of investigation to study the landuse and the management of local resources during the last three...

The lost phytoliths of Naachtun (Petén, Guatemala): Development of a modern reference for the characterization of plant environments in the Maya Tropical Lowlands
Phytoliths, unlike pollen and charcoal, are frequently conserved in sediments in the Maya lowlands but are rarely used as paleoenvironmental proxies. To better interpret and reconstruct paleoecological signatures and changes, it is necessary to provide current analogues of fossil assemblages. To do so, we selected six modern ecosystems and...
