“…[46] clearly observed the expected pattern of higher nutrient removal by the alien subspecies, but, when applied in practice, Rodríguez et al . [47] observed a slightly higher nutrient removal by the native subspecies, especially towards phosphorus removal efficiency. According to Rodríguez and Brisson [47], this discrepancy can be related to the higher root biomass of the native P .…”

Functional Response (FR) and Relative Growth Rate (RGR) Do Not Show the Known Invasiveness of Lemna minuta (Kunth)

Growing travel and trade threatens biodiversity as it increases the rate of biological invasions globally, either by accidental or intentional introduction. Therefore, avoiding these impacts by forecasting invasions and impeding further spread is of utmost importance. In this study, three forecasting approaches were tested and combined to predict the invasive behaviour of the alien macrophyte Lemna minuta in comparison with the native Lemna minor: the functional response (FR) and relative growth rate (RGR), supplemented with a combined biomass-based nutrient removal (BBNR). Based on the idea that widespread invasive species are more successful competitors than local, native species, a higher FR and RGR were expected for the invasive compared to the native species. Five different nutrient concentrations were tested, ranging from low (4 mgN.L-1 and 1 mgP.L-1) to high (70 mgN.L-1 and 21 mgP.L-1). After four days, a significant amount of nutrients was removed by both Lemna spp., though significant differences among L. minor and L. minuta were only observed at lower nutrient concentrations (lower than 17 mgN.L-1 and 6 mgP.L-1) with higher nutrient removal exerted by L. minor. The derived FR did not show a clear dominance of the invasive L. minuta, contradicting field observations. Similarly, the RGR ranged from 0.4 to 0.6 d-1, but did not show a biomass-based dominance of L. minuta (0.5 ± 0.1 d-1 versus 0.63 ± 0.09 d-1 for L. minor). BBNR showed similar results as the FR. Contrary to our expectations, all three approaches resulted in higher values for L. minor. Consequently, based on our results FR is sensitive to differences, though contradicted the expectations, while RGR and BBNR do not provide sufficient power to differentiate between a native and an invasive alien macrophyte and should be supplemented with additional ecosystem-based experiments to determine the invasion impact.

“…In addition, studying lineages can help us to understand how variants may impact on environments and how they behave under different management strategies. Recent studies focused on the common reed ( Phragmites australis ) have pointed out that different lineages behave differently with regard to their invasiveness, interspecific competition, and pollutant removal efficiency (Mozdzer, Brisson, & Hazelton, ; Rodríguez & Brisson, ). Different approaches have been developed to control weeds, including physical/mechanical and chemical methods.…”

Identification of independent evolutionary lineages is a modern challenge for biologists especially in crops with high potential. Molecular methods, usually used to explore intraspecific variation, also offer important information regarding how and when lineages have evolved and spread. Today, several tools to define the demarcation of lineages based on single or multi-locus data are available, permitting objective results to be obtained. We tested nuclear and plastid loci using five different approaches to delimit the major lineages and estimate the divergence times in giant reed (Arundo donax L.). It is an emerging energy crop, widespread in sub-tropical and temperate regions but particularly aggressive outside its native range. Our results support the presence of six lineages distributed from the Asian regions to the Mediterranean basin and indicate the western and southern edges of the Qinghai-Tibet Plateau as the putative area of origin and source of ancient and cryptic lineages. We suppose it could be an area that has fertile populations. These results should be considered in breeding programmes to produce new cultivars, especially because the absence of fertility for Mediterranean giant reed lineages reduces the opportunity of crop improvement. Moreover, the description of multiple lineages and identifying its putative ancestral area may be helpful to researchers working on invasiveness management, phytoremediation programmes and conservation biology.

“…Recently, Brezinová and Vymazal have evaluated the accumulation of heavy metals in above-ground biomass of P. australis and P. arundinacea in horizontal flow constructed wetlands for wastewater treatment (Březinová and Vymazal 2015;Vymazal and Březinová 2016). However, both P. arundinacea and P. australis are very competitive, and these plants often develop into the mono-dominant population in the natural ecological community by inhibiting the growth of other species (Adams and Galatowitsch 2005;Perkins and Wilson 2005;Kercher et al 2007;Rodriguez and Brisson 2015).…”

This study investigated the light utilization characteristics of Phalaris arundinacea within the Phalaris arundinacea-Phragmites australis compound community. The investigation was based on the response curve equation of the net photosynthetic rate-photosynthetic photon flux density (Pn-PPFD) of P. arundinacea and on the distribution of PPFD on the surface canopy of P. arundinacea within the compound community. Results showed that P. arundinacea was able to compensate for substantial reduction in available light, and utilize the weak light within the lower part of the compound community. On the one hand, the density of P. australis within the compound community determined the compensatory light utilization rate (CLUR) of P.arundinacea. On the other hand, the CLUR amplitude of P. arundinacea within the compound community with the same P. australis density was relatively small in a day. The results can help people to regulate P. arundinacea-P. australis compound communities to maintain a long-term, stable coexistence in the constructed wetlands.
