Upcoming below-ground field-campaign

We have still limited understanding of the mechanisms that shape the immense functional diversity and species richness of plants in tropical ecosystems. Such knowledge gaps hinder our ability to evaluate the impact that deforestation and soil degradation may have on forest regeneration and soil conservation. Our goal in this study is to highlight the importance of belowground processes in maintaining crucial ecosystem functions by investigating relationships among evolutionary phylogeny, morphological and physiological root traits and mycorrhizal associations in relation to soil nutrient availability in an integrated framework.


We aim to create the first curated collection of fine roots from tropical systems that will be accessible via an online library to the scientific community as well as to the general public. We therefore expect that this investigation will fill an important gap in root ecology by providing invaluable information about (1) how tropical trees are able to maintain efficient nutrient acquisition, (2) root functional traits present in tropical areas, and (3) resulting implications for management of forest regeneration and soil degradation under future scenarios.

CEBA thematic school 25-29. Sept. 2017

Remote sensing for tropical biodiversity mapping and management across scales

It has been an incredibly interesting and informative workshop including excellent discussions and exciting excursions to the Centre Spatial Guyanais (including an Ariane 5 rocket launch) and Paracou field station (sighting of a Jaguar!)

Launch of the Ariane 5 rocket

During the extremely informative and successful CEBA thematic school in Kourou, French Guiana CNES has launched an Ariane 5 rocket on Flight VA239 being the ninth launch in 2017. Conducted from the Spaceport’s ELA-3 launch zone the successful mission delivered an estimated payload lift performance of 10,838 kg to geostationary transfer orbit (GTO).

The mission carried Intelsat 37e for global operator Intelsat; along with BSAT-4a, which was launched as part of a turnkey contract between Japan’s Broadcasting Satellite System Corporation (B-SAT) and U.S.-based satellite manufacturer SSL. Intelsat 37e was deployed first in the flight sequence, separating from Ariane 5 at 29 minutes after liftoff, followed approximately 18 minutes later by BSAT-4a.
