“…On the basis of a hundred-year monitoring experience [7], it can be expected that Himalayan balsam in the study area might already be in the phase of exponential spreading. In principle, in comparison with the available reports from thoroughly investigated parts of Europe [9], we found nothing unusual about the type of vegetation Himalayan balsam invaded nor about the features of its habitat or mode of introduction and spread. The plant available concentrations of potentially harmful elements (Cd, Cr, Pb, and As) were low, below the phytotoxic levels, in a range reported for rural (not industrialized) areas [18].…”

“…The Himalayan balsam has been the focus of much research endeavors lately. In a very recent review [9], about 240 studies on this species published during the last two decades have been reported. In the EU, in particular, Impatiens glandulifera has become one of the 36 invasive alien plants of Union concern, which implies the obligation of the member countries to prevent unintentional introduction and commit to its eradication and management [10].…”

“…These circumstances implied some methodological limitations, most notably difficulties to identify suitable control sites (as discussed by [14,15]) to study the effect of Himalayan balsam on the resident vegetation. Besides, the effect of this alien invasive plant on domicile vegetation in its typical habitats of Europe (except for the southern areas) has been well investigated (reviews by [9,16]). On the other hand, there is very limited knowledge on the effects of environment on the invasion potential of this species, though it has been pointed out that species x environment interactions can importantly modify the invasion process [17].…”

An annual plant, Himalayan balsam (Impatiens glandulifera Royle) is globally widespread and one of Europe’s top invaders. We focused on two questions: does this species indeed not invade the southern areas and does the environment affect some of its key invisibility traits. In an isolated model mountainous valley, we jointly analyzed the soil (21 parameters), the life history traits of the invader (height, stem diameter, aboveground dw), and the resident vegetation (species composition and abundances, Ellenberg indicator values), and supplemented it with local knowledge (semi-structured interviews). Uncontrolled discharge of fecal wastewaters directly into the local dense hydrological network fostered mass infestation of an atypical habitat. The phenotypic plasticity of the measured invasion-related traits was very high in the surveyed early invasion (30–50% invader cover) stages. Different microhabitat conditions consistently correlated with its growth performance. The largest individuals were restricted to the deforested riparian habitats, with extreme soil nutrient enrichment (primarily by P and K) and low-competitive, species-poor resident vegetation. We showed that ecological context can modify invasion-related traits and what could affect a further invasion process. Finally, this species is likely underreported in the wider region; public attitude and loss of traditional ecological knowledge are further management risks.

“…Impatiens glandulifera Royle (Himalayan Balsam) is an annual plant, which is currently one of the most aggressive alien species in Europe [1][2]. The natural range of I. glandulifera is the Western Himalayas, where this species grows along river banks, in floodplain forests and in ruderal places, at altitudes of 1600-4300 m above sea level [3].…”

Distribution, naturalization status, invasion history and plant communities ofImpatiens glanduliferaRoyle (Balsaminaceae) in Siberia

All available data on the distribution of Impatiens glandulifera Royle in Siberia was analyzed. The species appeared in Siberia as an unpretentious ornamental plant around the middle of the 20th century. Cases of withdrawal from culture have been recorded since the 1970s and 1980s; mass naturalization began at the end of the 20th century. Currently, the species is common in many regions of Siberia, but the most active in the Altai Territory, the Altai Republic, Kemerovo, Novosibirsk, Tomsk and Irkutsk Regions. It is common in anthropogenic habitats; it can also often be found in suburban forests, ravines, along the banks of water bodies. It shows tolerance to habitat conditions, but is especially active in areas with a close occurrence of groundwater on humus-rich soils. The species richness of I. glandulifera communities is from 10-15 to 40 species. In total, about 100 species of vascular plants were recorded in I. glandulifera communities in Siberia

Phenological mismatches mitigate the ecological impact of a biological invader on amphibian communities

Horizon scans have emerged as a valuable tool to anticipate the incoming invasive alien species (IAS) by judging species on their potential impacts. However, little research has been conducted on quantifying actual impacts and assessing causes of species‐specific vulnerabilities to particular IAS due to persistent methodological challenges. The underlying interspecific mechanisms driving species‐specific vulnerabilities therefore remain poorly understood, even though they can substantially improve the accuracy of risk assessments. Given that interspecific interactions underlying ecological impacts of IAS are often shaped by phenological synchrony, we tested the hypothesis that temporal mismatches in breeding phenology between native species and IAS can mitigate their ecological impacts. Focusing on the invasive American bullfrog (Lithobates catesbeianus), we combined an environmental DNA (eDNA) quantitative barcoding and metabarcoding survey in Belgium with a global meta‐analysis, and integrated citizen‐science data on breeding phenology. We examined whether the presence of native amphibian species was negatively related to the presence or abundance of invasive bullfrogs and whether this relationship was affected by their phenological mismatches. The field study revealed a significant negative effect of increasing bullfrog eDNA concentrations on native amphibian species richness and community structure. These observations were shaped by species‐specific vulnerabilities to invasive bullfrogs, with late spring‐ and summer‐breeding species being strongly affected, while winter‐breeding species remained unaffected. This trend was confirmed by the global meta‐analysis. A significant negative relationship was observed between phenological mismatch and the impact of bullfrogs. Specifically, native amphibian species with breeding phenology differing by 6 weeks or less from invasive bullfrogs were more likely to be absent in the presence of bullfrogs than species whose phenology differed by more than 6 weeks with that of bullfrogs. Taken together, we present a novel method based on the combination of aqueous eDNA quantitative barcoding and metabarcoding to quantify the ecological impacts of biological invaders at the community level. We show that phenological mismatches between native and invasive species can be a strong predictor of invasion impact regardless of ecological or methodological context. Therefore, we advocate for the integration of temporal alignment between native and IAS's phenologies into invasion impact frameworks.
