Quantitative ecological inventory of terra firme and várzea tropical forest on the Rio Xingu, Brazilian Amazon
Three hectares of Amazonian terra firme forest and an adjacent one-half hectare of várzea forest were quantitatively inventoried at O Deserto, on the Rio Xingu, Pará, Brazil. In the terra firmeExpand

A spatial model of tree α-diversity and tree density for the Amazon
Large-scale patterns of Amazonian biodiversity have until now been obscured by a sparse and scattered inventory record. Here we present the first comprehensive spatial model of tree α-diversity andExpand

The phylogenetic history and biogeography of the frankincense and myrrh family (Burseraceae) based on nuclear and chloroplast sequence data.
Generalized hypotheses for the vicariant, Gondwanan origin of pantropically distributed eudicotyledon families must be refined to accommodate recently revised dates that indicate major continentalExpand

THE CONTRIBUTION OF EDAPHIC HETEROGENEIYT TO THE EVOLUTION AND DIVERSITY OF BURSERACEAR TREES IN THE WESTERN AMAZON
Abstract —Environmental heterogeneity in the tropics is thought to lead to specialization in plants and thereby contribute to the diversity of the tropical flora. We examine this idea with data onExpand

INVESTIGATING PROCESSES OF NEOTROPICAL RAIN FOREST TREE DIVERSIFICATION BY EXAMINING THE EVOLUTION AND HISTORICAL BIOGEOGRAPHY OF THE PROTIEAE (BURSERACEAE)
Andean uplift and the collision of North and South America are thought to have major implications for the diversification of the Neotropical biota. However, few studies have investigated how theseExpand

Bamboo-Dominated Forests of the Southwest Amazon: Detection, Spatial Extent, Life Cycle Length and Flowering Waves
We map the extent, infer the life-cycle length and describe spatial and temporal patterns of flowering of sarmentose bamboos (Guadua spp) in upland forests of the southwest Amazon. We first examineExpand

To move or to evolve: contrasting patterns of intercontinental connectivity and climatic niche evolution in “Terebinthaceae” (Anacardiaceae and Burseraceae)
Many angiosperm families are distributed pantropically, yet for any given continent little is known about which lineages are ancient residents or recent arrivals. Here we use a comprehensive samplingExpand
