“…One such approach is phytoremediation using rapid highbiomass producing plants, which use natural solar energy to stabilize, remove, degrade, or otherwise deal with contaminants (Prasad 2004;Rai 2009). E. densa is one ideal example, as it grows all over the world and produces a large biomass (Mony et al 2007;Maleva et al 2012). Photosynthesis is one of the leading functions of plants.…”

This paper analyzes the effect of exogenous urea in increased concentration gradient (0, 100, 500 and 1,000 mg L −1 ) on photosynthetic pigments (measured spectrophotometrically), uptake of 14 CO 2 (using radioisotope), and urease activity (by measuring ammonia with Nessler's reagent) in leaves of Elodea densa Planch. We have observed that low concentration of urea (100 mg L −1 ) stimulates the accumulation of photosynthetic pigments and intensifies photosynthesis in E. densa, whereas high concentration (1,000 mg L −1 ) suppresses these processes. Urease activity increased by approximately 2.7 and 8 fold when exogenous urea concentrations were 100 and 500 mg L −1 , respectively. However, exogenous urea in high concentration (1,000 mg L −1 ) decreased urease activity by 1.5 fold compared to the control. The necessity of mitigating urea and other nitrogen-containing compounds (NH 3 from urea) in water bodies has been discussed with emphasis on the potential for phytoremediation of urea using common water weed viz. E. densa.

“…A large body of evidence supports rapid contemporary adaptation of introduced plants to novel environments (Prentis et al 2008) and the competitive ability of Hydrilla is well documented (Mony et al, 2007;Spencer and Ksander, 2000 ). However, information on Mayaca is lacking as it has only recently recognized as a problematic plant.…”

“…In one case of herbaceous invasions, there is evidence of higher competitive ability of the secondary invader Fallopia japonica, over the primary invader Gunnea tinctoria, which was displaced by F. japonica over a few years (Gioria et al 2011). In cases of competition between two invaders, higher morphological plasticity is one of the reasons for superior competitive ability of one species (Mony et al 2007).…”

Interaction between invasive and potentially invasive shrub species does not influence relationships between their ecological success and distance from propagule sources

Although interactions between alien and native plant species are well studied, data on interactions between two co-existing alien species with respect to their invasibility are scarce. The aims of this study were (1) to evaluate three factors shaping abundance of the alien shrub species Cornus alternifolia: abundance of another alien (invasive) shrub species (Prunus serotina), type of tree stand (coniferous vs. broadleaved) and distance to propagule sources and (2) to assess the potential dispersal distance of the species studied. Densities of both species were assessed within 194 experimental plots (located in experimental plantations of trees) in Rogów Arboretum (Central Poland). P. serotina occurred on 79 and C. alternifolia on 33 of the 194 plots. The furthest distance of C. alternifolia from the propagule source was 338 m. C. alternifolia reached higher densities in coniferous than broadleaved tree stands. Density of C. alternifolia depended on tree stand type and distance from the propagule source, but did not depend on density of P. serotina. Density of C. alternifolia decreased with increasing distance from the propagule source; however, this relationship was modified by the type of tree stand: densities were lower in broadleaved than in coniferous stands. The presence of the invasive species seems to neither facilitate nor limit the dispersal distance of C. alternifolia, as these two species differ in shade tolerance. The study also provided the first information about C. alternifolia potential invasiveness, because earlier this species was noticed only as casually escaping from cultivation in Slovakia.
