Agricultural systems have a long history of responding to various economic and socio-political forces, including supply and demand, political preferences and power inequalities. Our current food system continues to respond to contemporary forces with a call for sustainable transformations in the face of increased pressure and competition over resources, severe consequences of climatic change, widespread degradation of land and...
Global root traits (GRooT) databaseNARA Subscribed
Motivation Trait data are fundamental to the quantitative description of plant form and function. Although root traits capture key dimensions related to plant responses to changing environmental conditions and effects on ecosystem processes, they have rarely been included in large‐scale comparative studies and global models. For instance, root traits remain absent from nearly all studies that define the global spectrum of plan...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
The importance of plant genotype and contemporary evolution for terrestrial ecosystem processesNARA Subscribed
Plant genetic variation and evolutionary dynamics are predicted to impact ecosystem processes but these effects are poorly understood. Here we test the hypothesis that plant genotype and contemporary evolution influence the flux of energy and nutrients through soil, which then feedback to affect seedling performance in subsequent generations. We conducted a multiyear field evolution experiment using the native biennial plant O...
AgroforestryNARA Subscribed
375Blowing and drifting snow on Minnesota's roadways is a transportation efficiency and safety concern. Living snow fence is an agroforestry system involving planting of woody/tree species such as hybrid poplars, willow, other shrubs and pine trees along drifting snow areas. Establishing living snow fences improves driver visibility and road surface conditions and has the potential to lower costs of road maintenance, reduce ac...
