“…Allelopathy is successfully used to control the growth and spread of competitive plant species both on land and in the ocean. In forestry it has been shown that natural 1 can impact the structure of entire plant communities. , The antagonistic relationship between phytoplankton and rooted aquatic plants has been investigated, and several other studies have described the allelopathic effect of marine natural products on marine algal communities. ,, Several of these characterized marine allelochemicals are of a phenolic nature, displaying structural similarities with the currently studied terrestrial compounds . As such, it is clear that the allelopathic phenomenon is ongoing on land and at sea, but it is nevertheless unclear if powerful terrestrial allelopathic compounds also will effectively target marine organisms to the same extent.…”

The current study reports the first comprehensive evaluation of a class of allelopathic terrestrial natural products as antifoulants in a marine setting. To investigate the antifouling potential of the natural dihydrostilbene scaffold, a library of 22 synthetic dihydrostilbenes with varying substitution patterns, many of which occur naturally in terrestrial plants, were prepared and assessed for their antifouling capacity. The compounds were evaluated in an extensive screen against 16 fouling marine organisms. The dihydrostilbene scaffold was shown to possess powerful general antifouling effects against both marine microfoulers and macrofoulers with inhibitory activities at low concentrations. The species of microalgae examined displayed a particular sensitivity toward the evaluated compounds at low ng/mL concentrations. It was shown that several of the natural and synthetic compounds exerted their repelling activities via nontoxic and reversible mechanisms. The activities of the most active compounds such as 3,5-dimethoxybibenzyl (5), 3,4-dimethoxybibenzyl (9), and 3-hydroxy-3′,4,5′-trimethoxybibenzyl (20) were comparable to the commercial antifouling booster biocide Sea-nine, which was employed as a positive control. The investigation of terrestrial allelopathic natural products to counter marine fouling represents a novel strategy for the design of “green” antifouling technologies, and these compounds offer a potential alternative to traditional biocidal antifoulants.

“…Under natural conditions, especially in eutrophic waters, epiphytic algae can shade submerged plants by up to 90%, decreasing their photosynthesis and growth (Bulthuis & Woelkerling, 1983 ; Koleszár et al, 2021 ; Phillips et al, 2016 ; Tóth, 2013 ). However, both species are able to produce allelopathic substances against blue green algae, thereby partly lowering the shading effect of periphyton (Nakai et al, 1999 ). In this way, those species equipped with a trait such as lower light compensation point might gain extra competitive advantage.…”

The synergy between climate change, eutrophication, and biological invasion is threatening for native submerged plants in many ways. The response of submerged plants to these changes is a key factor that determines the outcome of biological invasion. In order to explain the invasion successes, we investigated the combined effects of climate change and eutrophication‐related environmental factors (temperature, light, and nutrients) on the trait responses of a native (Myriophyllum spicatum) and an alien (Cabomba caroliniana) submerged species. In a factorial design, we cultivated the two species in aquaria containing low (0.5 mg N L−1, 0.05 mg P L−1) and high (2 mg N L−1, 0.2 mg P L−1) nutrient concentrations, incubated at four light intensities (average 25, 67, 230, and 295 μmol m−2 s−1 PAR photon flux density) under two temperature levels (21.5 and 27.5 ± 0.5°C). We used four invasion‐related functional traits (relative growth rate (RGR), specific leaf area (SLA), leaf dry matter content (LDMC), and nitrogen to carbon ratio (N:C molar ratio)) to measure the environmental response of the species. We calculated plasticity indexes to express the trait differences between species. Cabomba caroliniana showed significantly higher RGR and SLA than M. spicatum especially under low light intensity indicating that Cabomba is much more shade tolerant. Elevated temperature resulted in higher SLA and reduced LDMC for C. caroliniana indicating that Cabomba may have higher invasion success. Myriophyllum showed higher LDMC than C. caroliniana. Chemical analyses of the plant tissue revealed that although M. spicatum showed significantly higher N:C molar ratio, nonetheless, the daily nitrogen uptake of C. caroliniana was more than three times faster than that of M. spicatum. Results supported the idea that due to its higher shade tolerance and nitrogen uptake capacity, Cabomba likely has greater invasion success with increasing temperature combined with low light levels.

“…Its dense mats reduce recreational activities and crowd out native species, as well as altering the hydrology. Several authors (Nakai et al, 1999; Vanderstukken et al, 2011; Espinosa-Rodríguez et al, 2016) have found allelochemicals which affect phytoplankton negatively.…”

Allelopathic Effect of the Invasive Ludwigia hexapetala on Growth of Three Macrophyte Species

The release of allelochemicals by plants can affect the performance of other organisms positively or negatively. We tested the effects of aqueous extracts and leachates derived from the leaves and roots of the invasive water primrose (Ludwigia hexapetala) on one submerged native species – Ceratophyllum demersum, and two exotic species – the submerged Egeria densa and the emergent growth form of Myriophyllum aquaticum. The effect of the aqueous extracts and leachates of L. hexapetala on photosynthetic yield, growth (i.e., relative growth rate, leaf area), root length, and length of the lateral shoots of each species were analyzed in spring and in autumn. In autumn, an allelopathic effect was established on the traits of the three macrophytes species. The root extracts stimulated leaf area and the photosynthetic yield of C. demersum and of E. densa, whereas leaf treatments (leachates and extracts) and root leachate reduced the leaf area of M. aquaticum. The autumnal root leachate of L. hexapetala decreased the relative growth rate of C. demersum, whereas it had no effect on the two others plants. The root extract increased the length of lateral branches of M. aquaticum in autumn, suggesting a positive effect of L. hexapetala on the lateral growth of M. aquaticum. Three main allelochemicals were identified in leaves: quercitrin, prunin, myricitrin. The concentrations of these allelochemicals were greater in the leaf extract taken from L. hexapetala in autumn than in spring, and those found in the leaf leachates for both seasons. This assessment of autumnal allelopathy could help to explain the patterns of plant community succession in invaded areas.
