Intensive field sampling increases the known extent of carbon-rich Amazonian peatland pole forests
Peatland pole forest is the most carbon-dense ecosystem in Amazonia, but its spatial distribution and species composition are poorly known. To address this knowledge gap, we quantified variation in the floristic composition, peat thickness, and the amount of carbon stored above and below ground of 102 forest plots and 53 transects in northern Peruvian Amazonia. This large dataset includes 571 ground reference points of peat thickness measurements…
Persistent effects of pre-Columbian plant domestication on Amazonian forest composition
Past human influences on Amazonian forest The marks of prehistoric human societies on tropical forests can still be detected today. Levis et al. performed a basin-wide comparison of plant distributions, archaeological sites, and environmental data. Plants domesticated by pre-Columbian peoples are much more likely to be dominant in Amazonian forests than other species. Furthermore, forests close to archaeological sites often have a higher abundanc…

Hyperdominance in the Amazonian Tree Flora
Introduction Recent decades have seen a major international effort to inventory tree communities in the Amazon Basin and Guiana Shield (Amazonia), but the vast extent and record diversity of these forests have hampered an understanding of basinwide patterns. To overcome this obstacle, we compiled and standardized species-level data on more than half a million trees in 1170 plots sampling all major lowland forest types to explore patterns of commo…

MtDNA and Y‐chromosome diversity in Aymaras and Quechuas from Bolivia
Two Bolivian samples belonging to the two main Andean linguistic groups (Aymaras and Quechuas) were studied for mtDNA and Y‐chromosome uniparental markers to evaluate sex‐specific differences and give new insights into the demographic processes of the Andean region. mtDNA‐coding polymorphisms, HVI‐HVII control regions, 17 Y‐STRs, and three SNPs were typed in two well‐defined populations with adequate size samples. The two Bolivian samples showed …
Autosomal and X chromosome Alu insertions in Bolivian Aymaras and Quechuas
Thirty‐two polymorphic Alu insertions (18 autosomal and 14 from the X chromosome) were studied in 192 individuals from two Amerindian populations of the Bolivian Altiplano (Aymara and Quechua speakers: the two main Andean linguistic groups), to provide relevant information about their genetic relationships and demographic processes. The main objective was to determine from genetic data whether the expansion of the Quechua language into Bolivia co…
Drought Sensitivity of the Amazon Rainforest
Amazon forests are a key but poorly understood component of the global carbon cycle. If, as anticipated, they dry this century, they might accelerate climate change through carbon losses and changed surface energy balances. We used records from multiple long-term monitoring plots across Amazonia to assess forest responses to the intense 2005 drought, a possible analog of future events. Affected forest lost biomass, reversing a large long-term car…
