The definitive version was published in BMC Bioinformatics 14 (2013): 16, doi:10.1186/1471-2105-14-16.The digitization of biodiversity data is leading to the widespread application of taxon names that are superfluous, ambiguous or incorrect, resulting in mismatched records and inflated species numbers. The ultimate consequences of misspelled names and bad taxonomy are erroneous scientific conclusions and faulty policy decisions. The lack of tools for correcting this ‘names problem’ has become a fundamental obstacle to integrating disparate data sources and advancing the progress of biodiversity science. The TNRS, or Taxonomic Name Resolution Service, is an online application for automated and user-supervised standardization of plant scientific names. The TNRS builds upon and extends existing open-source applications for name parsing and fuzzy matching. Names are standardized against multiple reference taxonomies, including the Missouri Botanical Garden's Tropicos database. Capable of processing thousands of names in a single operation, the TNRS parses and corrects misspelled names and authorities, standardizes variant spellings, and converts nomenclatural synonyms to accepted names. Family names can be included to increase match accuracy and resolve many types of homonyms. Partial matching of higher taxa combined with extraction of annotations, accession numbers and morphospecies allows the TNRS to standardize taxonomy across a broad range of active and legacy datasets. We show how the TNRS can resolve many forms of taxonomic semantic heterogeneity, correct spelling errors and eliminate spurious names. As a result, the TNRS can aid the integration of disparate biological datasets. Although the TNRS was developed to aid in standardizing plant names, its underlying algorithms and design can be extended to all organisms and nomenclatural codes. The TNRS is accessible via a web interface at http://tnrs.iplantcollaborative.org/ webcite and as a RESTful web service and application programming interface.

Biodiversity recovery of Neotropical secondary forests

Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests that regrow on abandoned agricultural lands increase in extent. We assess how tree species richness and composition recover during secondary succession across gradients in environmental conditions and anthropogenic disturbance in an unprecedented multisite analysis for the Neotropics. Secondary forests recover remarkably fast in species richness but slowly in species composition. Secondary forests take a median time of five decades to recover the species richness of old-growth forest (80% recovery after 20 years) based on rarefaction analysis. Full recovery of species composition takes centuries (only 34% recovery after 20 years). A dual strategy that maintains both old-growth forests and species-rich secondary forests is therefore crucial for biodiversity conservation in human-modified tropical landscapes.

Taking the pulse of Earth's tropical forests using networks of highly distributed plots

Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science. Our core approach involves linking long-term grassroots initiatives with standardized protocols and data management to generate robust scaled-up results. By connecting tropical researchers and elevating their status, our Social Research Network model recognises the key role of the data originator in scientific discovery. Conceived in 1999 with RAINFOR (South America), our permanent plot networks have been adapted to Africa (AfriTRON) and Southeast Asia (T-FORCES) and widely emulated worldwide. Now these multiple initiatives are integrated via ForestPlots.net cyber-infrastructure, linking colleagues from 54 countries across 24 plot networks. Collectively these are transforming understanding of tropical forests and their biospheric role. Together we have discovered how, where and why forest carbon and biodiversity are responding to climate change, and how they feedback on it. This long-term pan-tropical collaboration has revealed a large long-term carbon sink and its trends, as well as making clear which drivers are most important, which forest processes are affected, where they are changing, what the lags are, and the likely future responses of tropical forests as the climate continues to change. By leveraging a remarkably old technology, plot networks are sparking a very modern revolution in tropical forest science. In the future, humanity can benefit greatly by nurturing the grassroots communities now collectively capable of generating unique, long-term understanding of Earth's most precious forests.Additional co-authors: Susan Laurance, William Laurance, Francoise Yoko Ishida, Andrew Marshall, Catherine Waite, Hannsjoerg Woell, Jean-Francois Bastin, Marijn Bauters, Hans Beeckman, Pfascal Boeckx, Jan Bogaert, Charles De Canniere, Thales de Haulleville, Jean-Louis Doucet, Olivier Hardy, Wannes Hubau, Elizabeth Kearsley, Hans Verbeeck, Jason Vleminckx, Steven W.

Synthèse sonochimique de nanomatériaux et sonocatalyse

International audienceLes traitements ultrasonores peuvent être réalisés dans une large gamme de conditions opératoires permettant ainsi de générer des effets physiques et chimiques dans des milieux aussi bien à température ambiante qu’en conditions hydrothermales.Grâce à ces spécificités, la sonochimie apparait comme une technique particulièrement intéressante pour la préparation de matériaux de nature chimique variée et permet la conception de voies de synthèses innovantes. Différents protocoles ont ainsi été développés au sein de notre laboratoire mettant notamment en œuvre la réduction sonochimique de métaux nobles mono ou bimétalliques sur des supports polymériques thermosensibles de taille contrôlée sans ajouts de réactifs. Ces matériaux ont ensuite été utilisés comme agents porogènes et vecteurs de la phase active pour la synthèse de catalyseurs supportés à porosité hiérarchique et à designs originaux [1-2]. Une autre approche que nous avons étudiée concerne l’élaboration de nanomatériaux de type cœur coquille Ti@TiO2 obtenus au cours d’un traitement sonohydrohtermal à 200 °C sous 13 bar et irradiation ultrasonore simultanée à 20 kHz. Les propriétés optiques spécifiques de ces catalyseurs ont ensuite été exploitées pour la génération d’hydrogène au cours de l’irradiation, dans le visible et le proche infrarouge, de solutions aqueuses en présence de composés organiques sacrificiels [3].L’utilisation du phénomène de cavitation acoustique ne se limite cependant pas à la synthèse de matériaux et permet également d’envisager des applications en sonocatalyse et en particulier pour les réactions d’oxydation et de dégradation des polluants organiques. En effet, la génération in situ d’espèces oxydantes réactives et peu sélectives comme les radicaux OH·, permet de considérer la sonochimie comme une technique d’oxydation avancée pour la décontamination des effluents aqueux. Cependant, les quantités de radicaux formés restent généralement faibles, de l’ordre de la µmol.min-1, et ne permettent de traiter que des effluents faiblement pollués. Ainsi, différentes études au sein de notre laboratoire ont mis en évidence que le phénomène de cavitation acoustique permettait d’activer certains catalyseurs comme Co3O4/TiO2 pour la défonctionalisation de l’EDTA ou bien d’augmenter les performances catalytique de Pt/TiO2 au cours de la minéralisation des acides carboxyliques à 40 °C en présence d’oxygène sous irradiation ultrasonore à haute fréquence [4-5].[1].

Deciphering the reaction mechanisms of photothermal hydrogen production using H/D kinetic isotope effect

International audienceH/D kinetic isotope effect has been employed to study the mechanism of the thermally assisted photocatalytic hydrogen production over noble metal-free Ti@TiO2 core–shell nanoparticles. We have found that the observed large H/D isotope separation factor (αH = 11.3 ± 1.7–6.2 ± 0.9) is due to the electron hole-mediated cleavage of OH bond. It was concluded that strong H/D isotopic selectivity is associated with significant photothermal effect

Titanium Oxide-Based Noble Metal-Free Core-Shell Photocatalysts for Hydrogen Production

International audiencePhotocatalytic and photo-electrocatalytic production of hydrogen from water is considered as a promising solution for solar energy storage issue. The feasibility of solar fuel technologies depends on the performance of catalysts, which should meet several strict requirements. They should be active under the solar light, chemically and photochemically stable, nontoxic, and cost-effective. In this view, preparation of effective photocatalysts from earth-abundant elements is of great importance for sustainable energetics. Among the large variety of photocatalysts studied during the past decades, the catalysts based on titanium oxide have attracted much attention. However, a quite large bandgap and rapid electron-hole recombination are the serious bottlenecks of TiO2photocatalyst. The recent advances in photocatalysis with TiO2-based materials pointed out several strategies of TiO2bandgap engineering, such as doping of TiO2 with cations or anions and surface sensitization with organic dyes or transition metal complexes. On the other hand, fabrication of TiO2heterojunctions with other semiconductors and TiO2 loading with cocatalysts allows to minimize electron-hole recombination during the photocatalytic process. Design of catalyst morphology is an important strategy to reach maximal photocatalytic activity. This chapter is primarily focused on titania-based core-shell photocatalysts fabricated from earth-abundant elements for efficient and cost-effective hydrogen production. Special attention is also paid to the photothermal effect in solutions, which has recently been proven to be promising for more efficient photocatalytic solar light conversion

Insights into the Photothermal Hydrogen Production from Glycerol Aqueous Solutions over Noble Metal-Free Ti@TiO 2 Core-Shell Nanoparticles

International audiencePhotocatalytic production of hydrogen from renewable sources with platinum group metal‐free catalysts is of great importance for environmentally friendly energetics. Herein, Ti@TiO2 core–shell nanoparticles prepared by sonohydrothermal treatment of titanium metal nanoparticles are examined for hydrogen generation from aqueous glycerol solutions under vis/NIR light irradiation. It is shown that photocatalytic reforming of glycerol in the presence of Ti@TiO2 exhibits strong photothermal effect allowing more efficient use of solar energy. Apparent activation energy equal to E act = 27 ± 2 kJ mol−1 indicates that the thermal effect is related to the diffusion of reaction intermediates at catalyst surface rather than to the activation of chemical bonds. The photoexcitation mechanism of Ti@TiO2 particles involves interband transitions in nonplasmonic Ti metal core followed by nonradiative Landau damping. Effective electron–hole separation between Ti core and nanocrystalline TiO2 anatase shell in Ti@TiO2 nanoparticles is confirmed by photoluminescence spectroscopy. In studied system, photothermal hydrogen production is not accompanied by CO2 emission indicating that glycerol is oxidized to glyceric acid without further decarboxylation
