Impact of plant invasion ( Solidago gigantea L.) on soil mesofauna in a riparian wet meadows

Relationships between alien plant species and their aboveground effects have been relatively well studied, but little is known about the effects of invasive plants on belowground faunal communities. Nematodes are abundant, ubiquitous and diverse soil biota, and alterations of their community compositions can illustrate changes in belowground ecosystems. In 2016 and 2017, we determined the response of species diversity, community composition and trophic composition of the soil nematode communities to invasion by the alien plant Solidago gigantea in two ecosystems, forest and grassland, where invasion takes place. Nematode abundance was higher and number of identified nematode species was lower at invaded than uninvaded sites, indicated by lower species diversity, regardless of ecosystem. Herbivorous nematodes were the most affected trophic group. Herbivore abundance was higher at invaded than uninvaded sites and in grassland than forest. The herbivorous species Boleodorus thylactus, Geocenamus sp., Helicotylenchus spp., Paratylenchus bukowinensis, Pratylenchoides crenicauda and Rotylenchus robustus were more abundant at the invaded sites. Abundances of nematodes in the other tropic groups were limited or not affected. The invasion did not significantly affect the ecological and functional indices, except for the Channel Index in 2016. Differences were observed in values of Enrichment Index (indicator of resource availability), Channel Index (indicator of ascendant bacterial/fungal decomposition channel) and Basal Index (indicator of depleted-perturbed soil food webs) between grassland and forests. We can thus conclude that invasion by S. gigantea significantly alters nematode community indicators (abundance, species diversity and specific trophic groups); however, this effect seems to be significantly influenced by the type of ecosystem where invasion takes place.

“…The invasion of goldenrod brings about a strong change in the physical-chemical properties of the soil and causes significant changes in the above-ground communities of arthropods at different trophic levels (Sterzyńska et al, 2017). Goldenrod is very popular among beekeepers because of its rich autumn grazing and in traditional medicine for wound healing and urinary tract inflammation.…”

In nature there are more and more problems caused by invasive alien plant species. They not only threaten and displace native plants, but also cause economic damage. The aim of this study was to investigate and determine the percentage of weeking of prints on papers made from invasive alien plant species, i.e. Japanese knotweed and goldenrod. The same pattern was printed on both invasive alien plant species papers, Japanese knotweed and goldenrod, using two different printing techniques, i.e. inkjet and electrophotographic. We measured the percentage of the appearance of the week on both printing techniques. The highest percentage deviation of 9.42% was found on paper made of cellulose fibres obtained from goldenrod using the inkjet printing process, while the deviation from the ideal print using the electrophotographic printing process on the same paper was 2.02%. From the research results we can conclude that the electrophotographic printing technique is more suitable for printing on papers made from invasive alien plant species.

“…Invasive alien plants present serious problems for biodiversity. Moreover, alien plants can generate environmental and agricultural threats in the areas in which they invade, and then negatively impact upon natural organization, resulting in enormous economic losses [1,2,3,4,5,6]. Therefore, it is desirable that invasive alien plants are converted into useful materials that can provide environmental and economic benefits.…”

Electron Beam Irradiation Isolates Cellulose Nanofiber from Korea “Tall Goldenrod” Invasive Alien Plant Pulp

This work investigates the possibility of isolating cellulose nanofibers from pulps of tall goldenrod plant, which are invasive plants in Korea, by a convenient method, without strong acids or high-pressure homogenization, using electron beam irradiation (EBI). The obtained cellulose nanofibers were characterized by scanning electron microscopy (SEM), ultraviolet–visible (UV–vis) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and in terms of their mechanical properties. SEM showed that the initially isolated 10-μm-diameter cellulose fibers became more finely separated with increasing EBI dose, and that cellulose fibers treated with 300 kGy of EBI were separated into long cellulose nanofibers of around 160 nm in diameter. In addition, the paper samples prepared from more finely separated fibers generated by using higher doses of EBI had enhanced UV–vis transmittance. Via the XRD analysis, we observed that cellulose I in the EBI-treated cellulose fibers were gradually converted into a different type of cellulose similar to cellulose type II, as the EBI dose increased. Meanwhile, the TGA demonstrated that the finely separated cellulose fibers observed after administering the high EBI dose had lowered thermal stability due to the reduction of cellulose I but higher char yield. In addition, tensile strengths of paper samples increased with decreasing the diameters of their constituent fibers that result from the different EBI doses used in the preparation of the paper pulp.
