Invasive and native plants can coexist in the same habitat; however, the decomposition process may be altered by the mixing of invasive and native leaves. Heavy metal contamination may further alter the co-decomposition of both leaf types. This study evaluated the effects of two concentrations (35 mg·L−1 and 70 mg·L−1) and three types (Pb, Cu, and combined Pb + Cu) of heavy metal contamination on the co-decomposition of leaves of the invasive tree Rhus typhina L. and the native tree Koelreuteria paniculata Laxm, as well as the mixed effect intensity of the co-decomposition of the mixed leaves. A polyethylene litterbag experiment was performed over six months. The decomposition coefficient of the two trees, mixed effect intensity of the co-decomposition, soil pH and enzymatic activities, soil bacterial alpha diversity, and soil bacterial community structure were determined. A high concentration of Pb and combined Pb + Cu significantly reduced the decomposition rate of R. typhina leaves. A high concentration of Pb or Cu significantly reduced the decomposition rate of the mixed leaves. In general, R. typhina leaves decomposed faster than K. paniculata leaves did. There were synergistic effects observed for the co-decomposition of the mixed leaves treated with combined Pb + Cu, regardless of concentration, but there were antagonistic effects observed for the co-decomposition of the mixed leaves treated with either Pb or Cu, regardless of concentration. A high concentration of Pb or Cu may increase antagonistic effects regarding the co-decomposition of mixed-leaf groups. Thus, heavy metal contamination can significantly affect the intensity of the mixed effect on the co-decomposition of heterogeneous groups of leaves.

“…Shifts in climate leading to changed local hydrological/thermal conditions tend to favor IAPS range expansion, given their strong dispersal, establishment and stress adaptation traits. For example, alterations to low/high flow periodicity can stress native plants and so create openings for IAPS (Henry et al, 2021; Hood & Naiman, 2000; Truscott et al, 2006). Flow variability shapes the composition and structure of riverine vegetation (Lytle & Merritt, 2004; Poff et al, 1997; Stromberg, Beauchamp, et al, 2007; Tockner et al, 2000), anthropogenic flow regulation can provide insights into the potential effects of disruptions in flood magnitude and timing expected under climate change (Mittal et al, 2016; Slater & Wilby, 2017).…”

Interacting effects of climate change and invasions by alien plant species on the morphodynamics of temperate rivers

This review explores the implications of climate change for the functioning of plant species as biogeomorphic engineers of temperate river systems, including the potential for an increasing role of invasive alien plant species (IAPS). First, we introduce engineer plants as important controls, along with flowing water and transported sediments, on the morphodynamics of river systems and the likelihood that climate change may affect the contributions of species within their native habitats. We then examine through the prism of the fluvial biogeomorphic succession model how climate change may accelerate the establishment of IAPS, the possible consequences for the performance and/or persistence of native engineer plant species, and thus the potential pathways of influence for IAPS on river morphodynamics. Finally, we present examples of the impacts of invasions by specific plant species along particular river systems and consider their potential biogeomorphic impact against a backdrop of climate change. Loss, replacement, or displacement of native plant species in the river corridor by IAPS can potentially alter biogeomorphic phenomena by directly increasing or decreasing erosion and/or sedimentation and the associated development of fluvial landforms. In the shorter term, increased climate disturbance may provide more establishment opportunities for opportunistic IAPS. In the longer term, under heavy establishment, IAPS may alter the coupled assembly of plant communities, fluvial landforms and ecosystem development, potentially resulting in river landscape metamorphosis and significantly changed habitat conditions.This article is categorized under: Science of Water > Water and Environmental Change Water and Life > Nature of Freshwater Ecosystems Water and Life > Stresses and Pressures on Ecosystems Water and Life > Conservation, Management, and Awareness
