Abstract:
... For clonal plants, spatial spread within a site is primarily determined by production of new ramets, which suggests that allocation to this function is a key component of the population and community dynamics of clonal plant species. However, surprisingly few studies, either theoretical or empirical, quantify the amount of resources that is or should be allocated to new daughters. Instead, the foc ...

Despite calls for large-scale reductions in material use and efforts to initiate a “circular economy” that promotes recycling and reuse, a limited decoupling between overall resource extraction and economic growth has been historically found. This is particularly true if resource use is measured with the life-cycle or consumption-based material footprint (MF) indicator that allocates material extr ...
