Research interests     

Our recent work on light limitation (Loiselle et al 2007, 2008) has introduced new approaches to the study of the controlling factors of primary production. These have been applied with success to tropical and mid-latitude ecosystems. In a recent publication (Loiselle et al. 2009), I have made the first systematic study of the spectral absorption slope of dissolved organic matter of different origins. This new approach addresses an important issue in the optical dynamics of ecosystems, and contributes to resolving a long debate regarding the optimisation of these approaches, as well facilitating comparisons among field studies. The Environmental Spectroscopy Group has made other important developments in the studies of the dynamics of dissolved organic matter (Bracchini et al. 2006, Galgani et al. 2010, Loiselle et al. 2009) and the role of this fundamental component in the aquatic carbon cycle, resulting in nearly 30 publications in peer reviewed journals in the last 5 years.
