Metabolomics of tropical forest soils and changes in response to nitrogen deposition.
EMSL Project ID
48871
Abstract
Tropical forests play a key role for mitigating climate change threats by sequestring anthropogenic carbon and are one of the most sensitive systems for global change scenarios. P is very limited in tropical ecosystems compared to N. Soils of tropical ecosystems are one of the most threatened systems under nitrogen deposition due the generation of an increasing imbalance with P that alters the C:N:P ratios of soils. The implementation of the new eco-metabolomics techniques in soils of tropical forests proposed here will show the changes in soil activity at molecular level and will reveal the key phenotypical responses of soils. The obtaining of metabolomic information in tropical soils under global change scenarios is thus crucial to increase the scientific knowledge of the soil metabolic processes that are directly related with the mineralization of soil organic matter and thus with the availability of nutrients for plants and the carbon emissions; a great debate that has already triggered geopolitical disputes. We propose the application of the metabolomics techniques using LC-MS, GC-MS and FT-ICR-MS for the analysis of the tropical soils of French Guaiana within the comprehensive research program of the IMBALANCE-P research project, which aims to understand the unknown consequenses for life, ecosystems and human society of the imbalances of N with P.Project Details
