Abstract:
... We synthesized composite microspheres from cellulose nanocrystal (CNC), polyvinyl alcohol (PVA), and sodium alginate (SA), which were modified with polyethyleneimine (PEI) to introduce a high density of active amino sites onto the surface via the Schiff base reaction. We hypothesized that these (SA/CNC/PVA)@PEI microspheres would have a high adsorption capacity for aqueous diclofenac sodium (DS).T ...

Abstract:
... Coevolution can promote long‐term coexistence of two competing species if selection acts to reduce the fitness inequality between competitors and/or strengthen negative frequency dependence within each population. However, clear coevolution between plant competitors has been rarely documented. Plant invasions offer opportunities to capture the process of coevolution. Here we investigated how the d ...

Abstract:
... The evolution of competitive ability plays an important role in plant invasions. While many studies of the evolution of invasive species have compared populations from native and invaded ranges in terms of their performance, little attention has been paid to the evolution of intraspecific competitive ability within the invaded range during range expansion. In addition, whether the proportional cha ...

Abstract:
... Many of the most invasive plants are clonal, and clonal integration has been proposed as an important mechanism promoting invasiveness. When the availabilities of two essential resources are negatively correlated in space, clonal integration may benefit clonal plants through division of labor. We hypothesized that environments with reciprocal patchiness of light and soil water may induce division ...
