1. Evolutionary patterns of volatile terpene emissions across 202 tropical tree species.

    Ecology and Evolution 6(9):2854 (2016) PMID 27069586 PMCID PMC4803801

    Plant responses to natural enemies include formation of secondary metabolites acting as direct or indirect defenses. Volatile terpenes represent one of the most diverse groups of secondary metabolites. We aimed to explore evolutionary patterns of volatile terpene emission. We measured the compos...
  2. Rare species contribute disproportionately to the functional structure of species assemblages.

    Proceedings of the Royal Society B: Biological ... 283(1828) (2016) PMID 27053754 PMCID PMC4843652

    There is broad consensus that the diversity of functional traits within species assemblages drives several ecological processes. It is also widely recognized that rare species are the first to become extinct following human-induced disturbances. Surprisingly, however, the functional importance o...
  3. Contributions of a global network of tree diversity experiments to sustainable forest plantations.

    Ambio 45(1):29 (2016) PMID 26264716 PMCID PMC4709352

    The area of forest plantations is increasing worldwide helping to meet timber demand and protect natural forests. However, with global change, monospecific plantations are increasingly vulnerable to abiotic and biotic disturbances. As an adaption measure we need to move to plantations that are m...
  4. The global spectrum of plant form and function.

    Nature 529(7585):167 (2016) PMID 26700811

    Earth is home to a remarkable diversity of plant forms and life histories, yet comparatively few essential trait combinations have proved evolutionarily viable in today's terrestrial biosphere. By analysing worldwide variation in six major traits critical to growth, survival and reproduction wit...
  5. Plant functional traits have globally consistent effects on competition.

    Nature 529(7585):204 (2016) PMID 26700807

    Phenotypic traits and their associated trade-offs have been shown to have globally consistent effects on individual plant physiological functions, but how these effects scale up to influence competition, a key driver of community assembly in terrestrial vegetation, has remained unclear. Here we ...
  6. Taxonomic and functional composition of arthropod assemblages across contrasting Amazonian forests.

    Journal of Animal Ecology 85(1):227 (2016) PMID 26346553

    Arthropods represent most of global biodiversity, with the highest diversity found in tropical rain forests. Nevertheless, we have a very incomplete understanding of how tropical arthropod communities are assembled. We conducted a comprehensive mass sampling of arthropod communities within three...
  7. A global meta-analysis of the relative extent of intraspecific trait variation in plant communities.

    Ecology Letters 18(12):1406 (2015) PMID 26415616

    Recent studies have shown that accounting for intraspecific trait variation (ITV) may better address major questions in community ecology. However, a general picture of the relative extent of ITV compared to interspecific trait variation in plant communities is still missing. Here, we conducted ...
  8. Effects of road infrastructure on forest value across a tri-national Amazonian frontier

    Biological Conservation 191:674 (2015)

    Road construction demonstrably accelerates deforestation rates in tropical forests, but its consequences for forest degradation remain less clear. We estimated a series of forest value metrics including components of biodiversity, carbon stocks, and timber and non-timber forest product...
  9. Rapid tree carbon stock recovery in managed Amazonian forests

    Current Biology 25(20):2738 (2015)

  10. Rapid tree carbon stock recovery in managed Amazonian forests.

    Current Biology 25(18):R787 (2015) PMID 26394096

    While around 20% of the Amazonian forest has been cleared for pastures and agriculture, one fourth of the remaining forest is dedicated to wood production. Most of these production forests have been or will be selectively harvested for commercial timber, but recent studies show that even soon af...

    Nature Communications 6:6857 (2015) PMID 25919449 PMCID PMC4423203

    While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few 'hyperdominant' species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosy...
  12. Pervasive Local-Scale Tree-Soil Habitat Association in a Tropical Forest Community.

    PLoS ONE 10(11):e0141488 (2015) PMID 26535570 PMCID PMC4633048

    We examined tree-soil habitat associations in lowland forest communities at Paracou, French Guiana. We analyzed a large dataset assembling six permanent plots totaling 37.5 ha, in which extensive LIDAR-derived topographical data and soil chemical and physical data have been integrated with preci...
  13. Estimating tropical tree diversity indices from forestry surveys: A method to integrate taxonomic uncertainty

    Forest Ecology and Management 328:270 (2014)

    • The taxonomic reliability of forestry surveys was tested in French Guiana rainforest. • The reliability was only 22% at species rank, 70% at genus and 83% at fam...
  14. Wood specific gravity and anatomy of branches and roots in 113 Amazonian rainforest tree species across environmental gradients.

    New Phytologist 202(1):79 (2014) PMID 24329812

    Wood specific gravity (WSG) is a strong predictor of tree performance across environmental gradients. Yet it remains unclear how anatomical elements linked to different wood functions contribute to variation in WSG in branches and roots across tropical forests. We examined WSG and wood anatomy i...
  15. Logging in bamboo-dominated forests in southwestern Amazonia: Caveats and opportunities for smallholder forest management

    Forest Ecology and Management 315:202 (2014)

    Science 342(6156):1243092 (2013) PMID 24136971

    The vast extent of the Amazon Basin has historically restricted the study of its tree communities to the local and regional scales. Here, we provide empirical data on the commonness, rarity, and richness of lowland tree species across the entire Amazon Basin and Guiana Shield (Amazonia), collect...
  17. Strong coupling of plant and fungal community structure across western Amazonian rainforests.

    ISME Journal 7(9):1852 (2013) PMID 23598789 PMCID PMC3749505

    The Amazon basin harbors a diverse ecological community that has a critical role in the maintenance of the biosphere. Although plant and animal communities have received much attention, basic information is lacking for fungal or prokaryotic communities. This is despite the fact that recent ecolo...
  18. Trans-boundary infrastructure and land cover change: Highway paving and community-level deforestation in a tri-national frontier in the Amazon

    Land Use Policy 34:27 (2013)

    Highlights ► We integrate biophysical and socioeconomic data across a tri-national frontier. ► Multivariate models estimate the impact of highway paving on land cover change. ► Paving status and travel time exert strong effects on deforestation across borders. ► Land tenure a...
  19. Insect herbivores, chemical innovation, and the evolution of habit specialization in Amazonian trees.

    Ecology 94(8):1764 (2013) PMID 24015520

    Herbivores are often implicated in the generation of the extraordinarily diverse tropical flora. One hypothesis linking enemies to plant diversification posits that the evolution of novel defenses allows plants to escape their enemies and expand their ranges. When range expansion involves enteri...
  20. Rare species support vulnerable functions in high-diversity ecosystems.

    PLoS Biology 11(5):e1001569 (2013) PMID 23723735 PMCID PMC3665844

    Around the world, the human-induced collapses of populations and species have triggered a sixth mass extinction crisis, with rare species often being the first to disappear. Although the role of species diversity in the maintenance of ecosystem processes has been widely investigated, the role of...
