Alien Invasive Plants

To enhance our understanding on plant invasions in China, we conducted a comparative study of the checklists of the alien invasive plants in China published during 1998-2008. Our results showed that species diversity of the invasive plants in China was relatively small, in consideration of the huge flora and diverse habitats in China. The results also indicated that there was a big turnover of species composition among the seven checklists. The fast-growth of species diversity of alien invasive plants during 1998-2008 and the exponentially increasing trend confirmed the early warnings. There was an increasing trend observed on those from Asia and Africa from 1998-2008. We suggested that extensive and intensive communication was pressingly needed among ecologists, taxonomists and authors of the checklists. The establishment of the checklist of alien invasive plants with high reliability and timely maintenance, which can accommodate the rapid turnover of the invaders, was one of the chief tasks in the research of plant invasions in China.

Abstract Allelopathy of alien invasive plants (AIP) on plant germination performance is essential for their successful invasion. However, the allelopathy of AIP may be reformed or even strengthened under acid deposition. AIP in Asteraceae covers the uppermost number of AIP species at the family level presently in China. It is necessary to estimate the allelopathy of multiple Asteraceae AIP under acid deposition to address the mechanism driving their successful invasion, especially under acid deposition. However, research in this area is very restricted presently. This study purposes to estimate the allelopathy of four Asteraceae AIP, i.e., Conyza canadensis L. Cronq., Erigeron annuus (L.) Pers., Aster subulatus Michx., and Bidens pilosa L., on germination performance of the cultivated Asteraceae plant species Lactuca sativa L. which is sensitive to allelochemicals under acid deposition with different levels of acidity. Of the four Asteraceae AIP, C. canadensis, E. annuus, and B. pilosa create noticeable allelopathy on germination performance of L. sativa. The allelopathy of the four Asteraceae AIP decreases in the following order: E. annuus, C. canadensis, B. pilosa, and A. subulatus. Acid deposition with a low level of acidity reduces the allelopathy of C. canadensis, E. annuus, and B. pilosa. Inversely, acid deposition with a high level of acidity elevates the allelopathy of B. pilosa. The progressively growing level of acid deposition with high acidity may facilitate the invasion process of B. pilosa via the improved level of allelopathy.

Description of the subject. Vegetation of high conservation value can establish in quarries, during or after exploitation. Alien plants could hamper this process and cause additional rehabilitation costs. However, the situation of plant invasion in quarries is largely unknown. Objectives. We aimed to assess alien plant invasion in active and abandoned quarries, and to identify the most invaded quarry sectors. Method. We surveyed 6,692 plots in 31 quarries in Belgium and recorded occurrence, density and cover of the 65 listed alien invasive plants in Belgium. Results. Fourteen species were recorded and 25 quarries contained at least one species. The two most occurring species, Buddleja davidii Franch. and Senecio inaequidens DC., were more widespread in quarries in activity. All sectors of the quarries were affected by alien plant invasion. Conclusions. Alien plant invasion in limestone quarries is highly variable, but significant. Considering the ecological potential of quarry sites, this issue should be better tackled.

Alien Invasive Plants

Invasive alien plants tend to grow much faster than non-invasive plants. The colonization by AM fungi is confirmed by the presence of mycorrhizal structures in the roots of invasive plants. The pattern of hyphae and arbuscules denotes Arum and Paris type of AM fungal morphology. The most common and abundant invasive plants from Asteraceae family were selected for the study. Ageratum conyzoides, Mikania micrantha, Ageratum haustonianum and Bidens Pilosa were selected and eventually showed that they have a high percentage of mycorrhizal colonization. Arum type of morphology is found in three of the plant species and Paris type of morphology is found in one of the species. The extent of AM fungal colonization is fairly high ranging from 60% to 90% among the studied plants. The percentage of arbuscular colonization is highest in Bidens pilosa and the percentage of vesicle and hyphal colonization is highest in Ageratum conyzoides.
