Abstract

A HYPERSPECTRAL REMOTE SENSING APPROACH TO STUDY THE BIOCHEMICAL PROPERTIES OF SENECIO INAEQUIDENS AND JACOBAEA VULGARIS Sabrina Carvalho12, Mirka Macel1, Martin Schlerf2, Wim van der Putten1 and Andrew Skidmore2 1Netherlands Institute of Ecology, Boterhoeksestraat 48, 6666 GA, Heteren, The Netherlands. 2 International Institute for Geo-information Science and Earth Observation-ITC, PO Box 6 7500 AA, Enschede, The Netherlands carvalho@itc.nl Understanding the mechanisms behind invasive species qualitative and quantitative success over time is a worldwide challenge. Ideally it should be possible to study plant gradients more thoroughly, taking specific component properties into account. Here we present how a considerably new technique - Hyperspectral Remote Sensing - offers the possibility for estimating foliar chemical concentrations over large geographic areas by using many subtle reflectance features (or absorption features) of the plant. Because soil-plant interactions cause variation in the chemistry of the plants this should be evident in the spectral signature of the plants when measured with spectroscopic tools and allow inferences over the influence of natural soil enemies in the plants. The project will implement field spectroscopy and spatial imagery to map several biochemicals of Senecio inaequidens, an invasive species, and Jacobaea vulgaris, a native species in the Netherlands. We will compare whether Senecio inaequidens is experiencing negative soil feedback of soil biota in the different successional stages or if the lack of pathogens in the new environment confers immunity. The knowledge gathered will improve our understanding of the plants-soil interactions in each of these groups and potentially allow us to successfully predict which variations may identify a species becoming invasive.
