    Abstract Gray foxes are successful habitat generalists within the temperate zone of their geographic range, exploiting a wide variety of habitats, including human-dominated landscapes. However, little is known of their use of tropical habitats or their ability to exploit landscapes with human activity. Here, we report the first study to explore the ecology and behavior of gray foxes within the tropics. Extensive camera-trap data (23,598 trap nights) across two different landscapes in Belize, combined with telemetry data on three collared individuals, showed a preference for more open and drier habitats over tropical moist broadleaf forest which is the dominant habitat type in the region. Although foxes did not use the interior of the broadleaf forests, they were detected at the edges and readily exploited areas that had been converted to support human activities (e.g., tourist centers). Home ranges of collared individuals were relatively large (3–7 km2) compared to those of temperate gray foxes, suggesting that they occupy a less productive landscape than those studied further north. This study found that although tropical gray foxes readily exploited human-altered landscapes, just as they do in the temperate zone, they are not the habitat generalists as previously thought and seem unable to fully exploit tropical moist broadleaf forest, the regions’ most dominant and productive habitat type.

    Abstract The genetic prehistory of human populations in Central America is largely unexplored leaving an important gap in our knowledge of the global expansion of humans. We report genome-wide ancient DNA data for a transect of twenty individuals from two Belize rock-shelters dating between 9,600-3,700 calibrated radiocarbon years before present (cal. BP). The oldest individuals (9,600-7,300 cal. BP) descend from an Early Holocene Native American lineage with only distant relatedness to present-day Mesoamericans, including Mayan-speaking populations. After ~5,600 cal. BP a previously unknown human dispersal from the south made a major demographic impact on the region, contributing more than 50% of the ancestry of all later individuals. This new ancestry derived from a source related to present-day Chibchan speakers living from Costa Rica to Colombia. Its arrival corresponds to the first clear evidence for forest clearing and maize horticulture in what later became the Maya region.

    Abstract Maize is a cultigen of global economic importance, but when it first became a staple grain in the Americas, was unknown and contested. Here, we report direct isotopic dietary evidence from 52 radiocarbon-dated human skeletons from two remarkably well-preserved rock-shelter contexts in the Maya Mountains of Belize spanning the past 10,000 years. Individuals dating before ~4700 calendar years before present (cal B.P.) show no clear evidence for the consumption of maize. Evidence for substantial maize consumption (~30% of total diet) appears in some individuals between 4700 and 4000 cal B.P. Isotopic evidence after 4000 cal B.P. indicates that maize became a persistently used staple grain comparable in dietary significance to later maize agriculturalists in the region (>70% of total diet). These data provide the earliest definitive evidence for maize as a staple grain in the Americas.

    Abstract We report genome-wide ancient DNA from 49 individuals forming four parallel time transects in Belize, Brazil, the Central Andes, and the Southern Cone, each dating to at least ∼9,000 years ago. The common ancestral population radiated rapidly from just one of the two early branches that contributed to Native Americans today. We document two previously unappreciated streams of gene flow between North and South America. One affected the Central Andes by ∼4,200 years ago, while the other explains an affinity between the oldest North American genome associated with the Clovis culture and the oldest Central and South Americans from Chile, Brazil, and Belize. However, this was not the primary source for later South Americans, as the other ancient individuals derive from lineages without specific affinity to the Clovis-associated genome, suggesting a population replacement that began at least 9,000 years ago and was followed by substantial population continuity in multiple regions.
