Individual and non-additive effects of exotic sap-feeders on root functional and mycorrhizal traits of a shared conifer host

Robert N. Schaeffer, Claire M. Wilson, Laura Radville, Mauri Barrett, Elizabeth Whitney, Sofia Roitman, Esther R. Miller, Benjamin E. Wolfe, Carol S. Thornber, Colin M. Orians, Evan L. Preisser Forest pests, exotic and native, are pervasive agents of tree stress and mortality worldwide. Their impacts are mediated through disruption of host functional traits that are…

Root traits are related to plant water-use among rangeland Mediterranean species

Florian Fort, Florence Volaire, Lydie Guilioni, Karim Barkaoui, Marie-Laure Navas, Catherine Roumet In the context of a global increase in the frequency and intensity of droughts under climate change, root traits need to be explored to better understand their influence on water-use strategies of plants and communities. Perennial Mediterranean herbaceous species are an interesting model…

REVIEW: Sampling roots to capture plant and soil functions

GrĂ©goire T. Freschet, Catherine Roumet The long and complex evolution of plant roots, and their occurrence in multiple environmental conditions, have shaped a large diversity of forms and functions among plant species. With the growing recognition that roots constitute a critical component of ecosystem functioning, an increasingly large research community has begun to unravel the…
