(2007)This dissertation presents multi-proxy evidence of paleoenvironmental change preserved in sediment records recovered from two lakes on the southern (Caribbean) slope of the Cordillera Central in the Dominican Republic: ... -
Paleodietary reconstruction of endemic rodents from the precolumbian Dominican Republic : discriminating wild feeding behavior from diets linked to human niche construction activities
(2022)In the Greater Antilles, certain animal taxa that have long been theorized to have been managed by indigenous peoples prior to AD1492, the main candidates being a group of endemic caviomorph rodents known as hutias ... -
Past and present of insular Caribbean mammals : understanding Holocene extinctions to inform modern biodiversity conservation
(2017)[English] Of the 116 mammal species present in the Greater Antilles at the start of the Holocene Epoch, only 56 now survive, with more extensive species losses (~80%) in native lineages of sloths, shrews, rodents, and ... -
